TO:HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM:JOHN SIGNO, DIRECTOR OF PLANNING & COMMUNITY SERVICES
THRU:ELAINE JENG P.E., CITY MANAGER
SUBJECT:RECEIVE AND FILE THE ANNUAL PROGRESS REPORTS FOR THE
GENERAL PLAN AND HOUSING ELEMENT.
DATE:March 28, 2022
BACKGROUND:
The annual progress reports (APRs) for the General Plan and Housing Element are due on
April 1, 2022. Government Code Section 65400 and 65700 mandates that all cities and
counties submit an annual report on the status of the General Plan and progress in its
implementation to their legislative bodies, the Governor's Office of Planning and Research
(OPR), and the Housing and Community Development (HCD). Government Code section
65400 also requires that each city, county, or city and county, including charter cities, prepare
an APR on the status of the housing element of its general plan and progress in its
implementation, using forms and definitions adopted by the California Department of Housing
and Community Development (HCD).
The APRs provide local legislative bodies and the public with information regarding the
implementation of the General Plan for their city or county. APRs also inform the public of the
progress in meeting the community’s goals. APRs must be presented to the local legislative
body for its review and acceptance, usually as a consent or discussion item on a regular
meeting agenda.
DISCUSSION:
The General Plan APR provides an overview of recent updates to elements and how the City
complies with OPR's guidelines. It summarizes the actions related to the General Plan over
the past year, including adopted ordinances and resolutions. It also summarizes the City's
efforts in updating the Housing Element and Safety Element.
The Housing Element APR is provided on a spreadsheet prepared by HCD. Activity in the City
over the past year include the submittal of nine accessory dwelling unit (ADU) applications and
issuance of two building permits for a new single-family residence at 11 Upper Blackwater
Canyon Road and an ADU at 1 Packsaddle Road. The new residence is reported as an above
moderate-income unit, while the ADU is reported as being a non-deed restricted moderate-
26
income unit. A report on the Local Early Action Planning (LEAP) is included in the Housing
Element APR as required by HCD.
FISCAL IMPACT:
None.
RECOMMENDATION:
Receive and file.

SUBJECT: ROLLING HILLS’ 2021 GENERAL PLAN ANNUAL PROGRESS REPORT
Dear Sir or Madam:
This serves as the City of Rolling Hills’ 2021 General Plan Annual Progress Report (GP APR) to
the Governor’s Office of Planning and Research (OPR).
The Rolling Hills General Plan was last updated in its entirety on June 25, 1990. Its purpose is to
comply with State law in guiding the physical development of the City; provide a long-range plan
for future development in the City, which is sensitive to existing development patterns; and
represents the desires of the community through an extensive public outreach process. The
Rolling Hills General Plan includes the following elements:
Land Use Element (Amended February 8, 2021)
Housing Element (5th Cycle adopted June 14, 2021)
Circulation Element
Open Space/Conservation Element
Safety Element (Currently being updated)
Noise Element
Compliance
The Rolling Hills General Plan complies with OPR’s General Plan Guidelines. The following is a
summary of actions related to the General Plan over the past year, including adopted ordinances
and resolutions:
The City currently has no moratoriums related to the General Plan.
On January 25, 2021, Ordinance No. 368 was adopted to establish a process by which
persons can request short-term use that might not meet the normal development or use
standards of the applicable zoning district, but may otherwise be acceptable on a
temporary basis.
On February 8, 2021, the City Council adopted Resolution No. 1270 amending the Land
Use Element and Land Use Policy Map to allow for multifamily housing, single room
occupancy, and emergency shelters.
28
Page 2 of 2
On February 22, 2021, Ordinance No. 369 was adopted to establish the Rancho Del Mar
Housing Opportunity Overlay Zone to accommodate housing in compliance with the 5th
Cycle Housing Element Update.
On June 14, 2021, City Council adopted Resolution No. 1277 adopting amendments to
the 2014-2021 Rolling Hills Housing Element (5th Cycle).
On December 14, 2021, Urgency Ordinance No. 372-U was passed to implement Senate
Bill 9 (“SB 9”), which involve urban lot splits and two-unit projects.
On December 14, 2021, Urgency Ordinance No. 373-U was passed to amend the Building
Code and adopt reference to the Los Angeles County Code because of local climatic,
geological, and topographical conditions.
On January 10, 2022, Ordinance Nos. 372 and 373 were adopted to permanently codify
the issues discussed in Urgency Ordinance Nos. 372-U and 373-U above, respectively.
Housing Element Update
The City has been diligently working on its 6th Cycle Housing Element. The Draft Housing
Element was sent to the Department of Housing and Community Development (HCD) on January
11, 2022 for review and comment. Although the 6th Cycle Housing Element was due in October
2021, the City was delayed because it was required to first adopt its 5th Cycle Housing Element,
which HCD certified on July 7, 2021. The City is currently awaiting comments from HCD on the
6th Cycle Housing Element, which it expects to receive by April 11, 2022. The City intends on
addressing HCD’s comments and adopting a Housing Element that meets HCD’s requirements.
This is expected to occur later on this year.
Safety Element Update
The City began its efforts to update the Safety Element in mid-2020 after being awarded a grant
from the Governor's Office of Emergency Services (CalOES). The City obtained the professional
services of Rincon Consultants, Inc. to prepare the Safety Element. Once completed, the Safety
Element was sent to the California Board of Forestry and Fire Protection for review, but no
recommendations or changes were made. On January 18, 2022, a presentation on the Safety
Element was made to the Planning Commission. The presentation provided an overview on new
legislation, policies, and topics included in the Safety Element. On February 15, 2022, the
Planning Commission held a public hearing and recommended unanimously that the City Council
adopt the Safety Element Update. On March 14, 2022, the City Council considered adopting the
Safety Element Update, however, due to concerns regarding the environmental document, the
Council continued the item to March 28, 2022. Staff has requested a time extension from CalOES
on the grant and expects to complete all requirements by mid-July 2022.
Thank you for your consideration. If you have any questions regarding the contents of this letter,
please feel free to contact me at 310-377-1521 or email jsigno@cityofrh.net.
Sincerely,
John F. Signo, AICP

TO:HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM:JOHN SIGNO, DIRECTOR OF PLANNING & COMMUNITY SERVICES
THRU:ELAINE JENG P.E., CITY MANAGER
SUBJECT:CONSIDER AND APPROVE THE PLANNED EXPENDITURES FOR
FISCAL YEAR 2022-2023 SAFE CLEAN WATER MUNICIPAL
PROGRAM FUNDS FOR SUBMISSION TO LOS ANGELES COUNTY
FLOOD CONTROL DISTRICT.
DATE:March 28, 2022
BACKGROUND:
In 2018, Los Angeles County voters approved Measure W (Safe Clean Water Municipal
Program Funds), a tax measure that is estimated to raise about $280 million annually for
storm water projects that build up the county’s water self-sufficiency. Funding is provided
through a parcel tax of 2.5 cents per square foot of impermeable land area (building, concrete,
etc.). The measure provides cities, watershed areas, and Los Angeles County with the funds
to capture, treat, and recycle storm water. The City Council has been involved in the planning
efforts and has approved the plans for how these funds have been and will be utilized to
advance the goals of the enabling legislation tied to Measure W.
DISCUSSION:
The LA County Flood Control District administers the program, distributes funds, provides staff
support and oversees capacity building programs. Cities receive funding through the Municipal
Program proportional to the revenues generated within its boundaries. The funds provide local
agencies the opportunity to identify programs that will best address its stormwater and urban
runoff. The funding
can be used for eligible activities such as project development, design, construction,
effectiveness monitoring, operations and maintenance, as well as for other programs and
studies related to protecting and improving water quality in lakes, rivers and ocean. To
receive funds, cities must submit their Safe Clean Water Municipal Program annually for
review and approval.
It is projected that the City will receive approximately $90,000 during FY2022/2023 in
Municipal Program Funds. The City must spend at least 70% of its Municipal Program Funds
on eligible expenses related to new projects or programs. Up to 30% of a City’s Municipal
Program Funds may be used to pay for eligible costs and expenses related to the continuation
38
of programs. Twenty percent (20%) of the City’s projected Municipal Program Funds will be
set aside in case revenues are lower than anticipated. Program funds are allocated as
described in the attached expenditure budget.
FISCAL IMPACT:
The City will receive approximately $90,000 during Fiscal Year 2022-2023 in Municipal
Program Funds. Previous revenue projections were $100,000.
RECOMMENDATION:
Approve as presented.

SUBJECT:RECEIVE AND FILE THE INITIAL JURISDICTION COMPLIANCE
REPORT TO BE SUBMITTED TO CALRECYCLE BY APRIL 1, 2022.
DATE:March 28, 2022
BACKGROUND:
CalRecycle requires each jurisdiction to report on its implementation and compliance with the
requirements of the regulations to implement Senate Bill 1383 (regulations), Title 14, Division
7, Chapter 12 of the California Code of Regulations (CCR). The attached form is used to
comply with the reporting requirement. The initial compliance report must be submitted to the
Department by April 1, 2022.
DISCUSSION:
Rolling Hills has been granted a low population waiver from CalRecycle due to its disposal of
less than 5,000 tons of solid waste in 2014 and the City's population being under 7,500. As
such, staff contact CalRecycle to ask if the reporting is necessary. CalRecycle staff indicated
that reporting is required, however, since the City is mostly single-family residential most
questions in the compliance report will be marked "not applicable." CalRecycle does require
recent ordinances dealing with waste, landscaping, and the Building Code to be included in
the submittal. Staff will include Ordinance No. 361 (Water Efficient Landscape Ordinance),
Ordinance No. 362 (Construction or Demolition Waste), Ordinance No. 373 (Building
Code/Fire Code), and Ordinance No. 374 (Edible Food Recovery) as part of the submittal.
These ordinances have all been passed by the City Council and are not attached to this
report.
FISCAL IMPACT:
None.

Proposal to the City of Rolling Hills
Fuel Load Reduction in 2022(Phase 4)
Submitted by the Palos Verdes Peninsula Land Conservancy
The Palos Verdes Peninsula Land Conservancy (Conservancy) is continues to be intimately
aware of the fire concerns on the Palos Verdes Peninsula, and continues to discuss measures
to reduce fire risk with the four peninsula cities. Conservancy staff members work with City of
Rolling Hills staff to implement fuel modification work as required by County Department of
Agriculture Weights and Measures as part of landowner responsibilities for fuel modification
near adjacent homes as well as measures above and beyond. Additionally, the Conservancy
clears over 90 acres of weeds in restoration sites within the Palos Verdes Nature Preserve and
clears 30+ miles of trails annually. This weeding approach is very specialized and must be
accomplished while complying with the NCCP/HCP implementation guidelines and respecting
the natural resources on the preserve. We understand that the city desires to continue to
prioritize efforts to reduce fuel load in Preserve areas, and the Conservancy understands that
vegetation exists beyond current fuel mod zones that pose fire threats. Therefore, the
Conservancy is offering technical expertise to aid the City and augment city staff in the effort
to continue reduce fuel load vegetation by targeting the removal of invasive plants such as
Acacia and Mustard and other non-native plants, which in turn improves habitat for local
wildlife, including the federally threatened coastal California gnatcatcher, the cactus wren, a
state species of concern and the federally endangered Palos Verdes Blue Butterfly.
This proposal outlines the potential areas for this extra 2022 work. The areas identified in
Portuguese Bend Reserve include the areas abutting and leading into Rolling Hills in Portuguese
Canyon, Ishibashi Canyon and Paintbrush Canyon. In total, an approximate 7 acres are
proposed for fuel load reduction in the Preserve. This work can be completed in less
than 4 weeks by simultaneously removing Acacia and mowing dry brush in order to
complete this work in a timely manner during fire season. For these additional
efforts, the Conservancy requests a one-time grant from the city up to $39,000 for
the proposed work outlined herein. The Conservancy understands the city’s timing
considerations and would be prepared to begin the work as soon as funding is made available.
The Conservancy has identified the priority removal of tall Acacia shrubs due to their combustible
nature (Acacia shrub contain an estimated 90% dry plant matter and volatile resins) and their
prevalence throughout the Preserve and border areas. The locations for the proposed Acacia
removal were chosen due to prior fires occurring in those areas, proximity to homes and risk to
the community as well as the ecological benefits of invasive plant removal. Fire agencies agree
that Acacia is a highly flammable plant and that it should be removed wherever possible. It was
included as a high-hazard plant in the L.A. County Fire Department’s recently published “Ready!
Set! Go!” pamphlet. This proposal also includes the removal of other non-native shrubs and trees
67
2
like Chinese Pistache, Myoporum and Ash trees. Mustard when dry, continues to be a high fire
risk species. The continued expansion of mowing areas is also included in this proposal.
The Conservancy, as Habitat Managers for the Preserve, has qualified experts on staff with the
experience required to oversee the work to be performed and will assure the correct and safe
removal of the invasive plants using the best techniques at the most efficient cost. The results of
this work will be shared with the City provided at the conclusion of the work performed.
Where possible and with simpler tasks, volunteers will be deployed to augment the work volume
and control costs. In ongoing maintenance activities, the Conservancy will create internship and
volunteer opportunities for invasive plant management to keep the Acacia from re-invading the
areas and to assist in monitoring activities. In this way, additional valuable learning opportunities
will be made available to local youth.
As projects are completed and conditions are assessed, restoration in these locations may be
appropriate and funding may be pursued, since this proposal does not include replanting in the
Acacia removal sites.
Acacia Removal
Approximately 1.5 acres
These Acacia removal sites are situated in the northern portion of Portuguese Bend Reserve along
the border with the city of Rolling Hills. A fire occurred at this location in 2009 burning
approximately 230 acres. Much of the vegetation was burned, including the non-native Acacia,
which has since begun to grow back from stump sprouting and seed germination.
It is recommended that crews enter the area on foot as possible and remove shrubs with
chainsaws and lighter equipment. Trees should be chipped in designated areas and treated to
prevent regrowth. The site will be monitored for seed germination and removal.
The Acacia throughout this area totals approximately 1.5 acres. This site is known habitat of
the federally threatened coastal California gnatcatcher and the cactus wren, a state species of
concern as well as other species of concern.
Mowing Area
Approximately 5.5 acres
There is a large stand of invasive mustard in west of Paintbrush Canyon that is dry and can be
mowed. This site is adjacent to historical farmland and were disked in subsequent years, so
the loose soils have provided a disturbance regime which is particularly favorable to mustard
and non-native grasses and weeds. Approximately 5.5 acres of mustard is at this location.
Slopes are very steep and high quality coastal sage scrub habitat is scattered throughout the
slope. Careful consideration to not damage native plants and close oversight will be needed.
In response to community concern about the vast expanse of dry mustard growth at
Portuguese Bend Reserve, the Conservancy will oversee mowing in this area and conduct
bird nesting surveys.

Budget
The budget reflects a typical detailed tree and shrub removal project within the preserve with
minimal disturbance to native habitat and to the surrounding vegetation, following NCCP/HCP
protocols. Careful non-native tree removals proposed in this project, increase the habitat value
for the federally threatened coastal California gnatcatcher and cactus wren, a state species of
concern, as well as other native species while providing public benefit. These costs reflect the
estimated time it would take the contractors to complete the project using hand tools and
machinery to either chip tree material or haul plant material offsite and oversight and bird
monitoring by Conservancy biologists to assure that best management practices are
implemented (ie. minimization and avoidance measures such as nesting bird surveys are required
by the NCCP/HCP).
These costs are based on best estimates provided by contractors for the Acacia removal and for
mowing as two separate projects. For maximum benefit for fuel load reduction and habitat,
both projects are recommended to be completed concurrently.
Project Acres Budget
Acacia Cutting and Chipping ~1.5 $13,200
Mowing of mustard ~5.5 $25,800
One-time Project Total ~7.5 $39,000

Other Project Considerations
This project is a worthwhile investment into the long-term benefit of the communities adjacent
to the open space and wildlife within. While more costly per acre to implement new, labor-
intensive work than annual fuel modification weed whacking efforts, removing Acacia and other
non-native trees is a positive, visible impact to the landscape and a one-time project cost to the
City in these target areas. This is unlike areas of mustard which, while needed to reduce fire
threat, require annual treatment and ongoing maintenance costs. To help ensure that this
investment is successful, the Conservancy recommends annual monitoring of areas to prevent
regrowth. This project strategy is supported by the Fire Department, which has identified Acacia
removal as a priority effort to reduce fire fuel load in the Preserve. This project is also
responding to the nearby community requests to respond to nuisance Acacia and mustard near
homes on the Preserve border.
Community Partnerships
As part of the Conservancy’s collaborative approach, we partner with various organizations to
complete projects and provide various benefits to the community. If the timing and logistics are
appropriate, we would work with some of our partner organizations to add to the costs savings.
We work with the Los Angeles Zoo and Botanical Gardens which accept fresh Acacia greenery
for the enhancement of their animal’s physical and mental health. We will save many of the
straight long branches from the Acacia tree for delineation of trails and to provide ground snags
for lizards and insects. We also have a partnership with the local schools that offer
woodworking classes for instructional teaching. Lastly, if the material does not contain seeds,
we will use the chipped wood as a mulch in fuel modification zones to keep weeds down into
the future.
The Conservancy will also engage the local colleges with applicable internships which allow
students to gain a better understanding of the natural world, resource management and gain
experience to prepare to enter the workforce. Thousands of hours of intern assistance with
projects have been logged and counting. By engaging these students who span from across
the globe, we are creating a lasting experience and leaving a lasting impression of the great
natural habitat that exists on the peninsula.
Currently the Conservancy is hosting an Americorp team and if schedule permits, the team
will assist with this project.
Potential for Restoration and Supplemental Work
As these projects are completed, the cleared land can provide opportunity for habitat restoration
and enhancement. A species that is potentially applicable to many of the local habitat types of
Palos Verdes, is our local cactus. While no plant is fireproof, there are certain characteristics
which make some plants more resistive to fire, such as cactus. Where applicable cactus can be
71
13
planted and maintained until establishment, if supplemental funding is available. Mature cactus
holds a mutual relationship with the cactus wren, a state species of concern, since the cacti
needles protect young nestlings from predators, providing the best habitat.
To make a larger impact, the Conservancy typically plants mature cactus that is appropriate for
immediate nesting, giving us more value per dollar spent. The approximate cost for planting and
maintaining a 1 acre cactus restoration project over a 5 year span is approximately $30,000, and
the Conservancy would be pleased to provide a restoration plan for lands along the Rolling
Hills border of the Preserve for the benefit of community and wildlife.

TO:HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM:ROBERT SAMARIO, FINANCE DIRECTOR
THRU:ELAINE JENG P.E., CITY MANAGER
SUBJECT:REVIEW SOLID WASTE COLLECTION SERVICE FEE INCREASE FOR
FY 2022-2023 AND CONSIDER SETTING PROPOSITION 218
REQUIRED PROTEST HEARING DATE.
DATE:March 28, 2022
BACKGROUND:
In March of each fiscal year, the City's refuse provider, Republic Services, requests an annual
increase to their rates pursuant to the agreement between the City of Rolling Hills and
Republic. Per Section 11.5b of the agreement, Republic can request an increase based on the
Consumer Price Index (CPI). For the twelve months ended June 2021, the CPI for "All Urban
Consumers" rose by 3.45%. As a result, Republic has requested an increase to t he current
rate per resident of $45.95 and would result in the current rate of $1,332.41 per year
increasing to $1,378.36 ($1,332.41 x 1.0345) starting July 1, 2021.
Although the City's payment to Republic per resident would increase to $1,378.36, the City
only charges City residents $1,100 per year. Beginning in fiscal year 2015/16, the City Council
has annually elected to forego passing on the rate increases to City residents and thereby
subsidizing trash rates from General Fund revenues, including taxes. The projected subsidy to
be provided to City residents from the General Fund for fiscal year 2022-23 is $190,677.
DISCUSSION:
Per state law, local governments that provide refuse and other utility services (e.g., water,
wastewater, etc.) are allowed to charge customers for the full cost to provide these services. In
addition, any proposed rate increases must be noticed, and a public hearing must be held 45
days after the date of the notice, prior to the implementation of rate increases. Residents can
reject any proposed rate increases with written protests by a majority of affected property
owners.
If the City Council wishes to increase refuse rates charged to City residents starting July 1,
2022, staff would need to send out notices to all City residents of such proposed rate
increases soon. If City Council elects not to pass on the rate increase and continue to
subsidize rates from the General Fund, no communication from staff to residents will be
73
necessary.
FISCAL IMPACT:
The fiscal impact to the General Fund would be an increase in the current refuse subsidy of
$159,199.48 to $190,676.60.
RECOMMENDATION:
Review refuse rate increase and provide direction for setting Proposition 218 protest hearing
date.

TO:HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM:CHRISTIAN HORVATH,
THRU:ELAINE JENG P.E., CITY MANAGER
SUBJECT:RECEIVE ADDITIONAL INFORMATION ON HQE SYSTEMS'
PROPOSED OUTDOOR SIREN SYSTEM AND DIRECT STAFF TO
CONDUCT A COMMUNITY SURVEY FOR FEEDBACK ON AN
OUTDOOR SIREN SYSTEM.
DATE:March 28, 2022
BACKGROUND:
In Fiscal Years 2019-2020 and 2020-2021, the City Council provided funding for the Block
Captain Program investigate communication platforms in the event of complete power failure
in the community. The Block Captains and city staff used funds to purchase two-way radios
and when the handheld radio option proved to be ineffective, a Request for Proposal (RFP)
was issued to solicit proposals on other communication systems. City staff presented a
feasibility proposal from HQE System Inc. (HQE) for an outdoor siren system.
On April 26, 2021, staff recommended that City Council engage the services of HQE. The City
Council directed Councilmember Jeff Pieper to work with staff to better understand the
evolution of the communication project and the scope of the feasibility study. As directed, staff
met with Councilmember Pieper on four occasions: May 20, 2021, July 15, 2021, July 23,
2021 and August 12, 2021. Some of the meetings with Councilmember Pieper included the
Lead Block Captains Arlene and Gene Honbo. Staff also worked with Project Manager Alan
Palermo and HQE to provide technical information requested by Councilmember Pieper. The
feasibility study by HQE Systems Inc. is intended to identify the hardware, location of the
hardware, software, system integration, and a detailed cost estimate to install a siren system
for the community. The Lead Block Captains, along with many members of the Block Captains
were in support of a feasibility study. The City Council ultimately engaged HQE to provide a
feasibility study.
At the January 10, 2022 City Council meeting staff presented the final feasibility report from
HQE and recommended the City Council to conduct a community survey to gauge interest for
an outdoor siren system. In review of the feasibility report, the City Council requested
information relating to the annual maintenance cost of the proposed outdoor siren system. The
City Council also requested a street level map of Option A and Option B presented in the
79
feasibility study.
DISCUSSION:
At the February 28, 2022 City meeting, the City Council had additional questions on HQE's
feasibility study. In Option A outlined in the feasibility report, Councilmember Leah Mirsch
asked if the poles have camouflage capability. HQE responded that all proposed poles can be
camouflaged.
In response to the City Council's request for street level maps to identify approximately
locations of proposed poles, HQE sent personnel to the city on March 9, 2022 to revisit sound
propagation points from their software to precisely locate proposed pole locations in the
community. HQE also took photos of proposed pole locations to enhance the review of street
level maps.
At the February 28, 2022 City Council meeting, Mayor Pro Tem Jim Black noted that the
community survey should include a question asking residents if they want a siren system if
poles needed to be placed on private property. Staff added one question to the community
survey for consideration.
FISCAL IMPACT:
Should the City Council decide to move forward with an outdoor siren system as proposed in
HQE's feasibility study, Solution A considered aesthetic for an estimated construction cost of
$310,602. Solution B offers the most reliable solution in the market today for an estimate of
$144,573. The anticipated annual m aintenance Cost is: $12,000.00 (increased at 3% inflation
rate per year).
The Fiscal Year 2021- 2022 adopted budget does not include funding for implementing an
outdoor siren system. The city has an annual subscription to Survey Monkey - online survey
system - funded by the operation budget for Fiscal Year 2021-2022. There would be no fiscal
impact should the City Council moves forward with a community survey.
RECOMMENDATION:
Receive additional information on HQE Systems' feasibility report and direct staff to conduct a
community survey.

Mass Notifications Systems Installation Report
The City of Rolling Hills, CA
1. Executive Summary
To the distinguished City of Rolling Hills’s City Council Members,
HQE Systems,Inc.(HQE)is a Minority-Owned,FEMA Certified Service-Disabled Veteran-Owned Small
Business (SDVOSB)with its global headquarters in Temecula,CA.Since 2014,HQE has been designing,
engineering,installing,and maintaining Mass Notification Systems (Central Control Units,Outdoor
Sirens,Control Cabinets,Radios,Solar Chargers,and Subcomponents of Mass Notification Systems)
solutions for a host of clients worldwide.HQE is a brand agnostic systems integrator that has installed
over 1,000+ Mass Notification Systems for all levels of the Government and Federal Agencies.
HQE was retained by The City of Rolling Hills,California,to investigate the feasibility of installing an
effective Mass Notification System.The intent of the system is to provide Mass Alerting and Warning in
the event of natural and manmade disasters including wildfires,terrorist events,and severe weather.
HQE’s Mass Notification Systems installation Report would provide the decision-makers with the
information needed to identify the ideal solution for The City of Rolling Hills.
To develop the report,HQE conducted an installation study.The study includes open-source data
research, site survey, and sound propagation analysis.
❖Open Source Data:Researching the latest solution from the key manufacturers.This includes
technical/operational features and rough order of magnitude pricing.
❖Site Survey:Study of the local environment/infrastructure to include the availability of power,
potential installation points,residential buildings,and topography (manmade and natural).In
addition,to analyze the presence and signal capabilities of cellular,radio,and other
communications channels.
❖Sound Propagation Analysis:Utilizing the information gathered during the site survey,GIS,and
DoD planning maps,HQE utilizes a proprietary machine-learning algorithm Sound Propagation
Analysis to determine the ideal locations for the Mass Notification points.
With all of the information reviewed and analyzed during the report development,HQE’s Mass
Notification Subject Matter Experts have determined two ideal installation options for The City of Rolling
Hills.These options were developed with the following priorities (not in order):Alerting Effectiveness,
Initial Budget, Sustainment Budget, Project Timeline, and System Installed Visibility.
Solution A (Low Visual Signature Installation Option):This solution was developed to provide The City
of Rolling Hills with a solution that provides the best visually pleasing option.This option will utilize the
SiRcom-Vector outdoor speaker arrays.These modern intelligible speakers will provide the “best-look”
for the City. The rough order of magnitude pricing for Solution A is, $310,601.53
Solution B (Lowest Cost Installation Option):This solution was developed to provide the best price
while maintaining the highest quality of outdoor warning capabilities.The solution utilizes the SiRcom
outdoor warning intelligible sirens.Although lowest in price,SiRcom is determined to be the most
reliable solution in the market today.The rough order of magnitude pricing for Solution B is,
$144,572.93

Mass Notifications Systems Installation Report
The City of Rolling Hills, CA
2. Background
The City of Rolling Hills (City)sought an installation report for Mass Notifications System (MNS).The
requirement specifically desired an effective outdoor solution that could operate in any threat event
environment.
The City of Rolling Hills relies primarily on communication tools that require electricity,cellular signal,or
access to the internet during an emergency.These methods include The City of Rolling Hills Website,
Alert Southbay,and local television/radio networks.Areas of California regularly experience power
outages during adverse,especially windy,weather conditions.The local utility provider utilizes a Public
Safety Power Shut-off (PSPS)program during inclement weather conditions.Because of the PSPS
program,residents of The City of Rolling Hills could possibly be without power during periods of
heightened fire danger,resulting in an increased risk of not receiving important communications,
including evacuation orders,via phone,internet,or radio.Unfortunately,disruption to the electrical
power also has a negative impact on local cellular towers which have limited generator power to sustain
its operational needs from the planned PSPS or electrical systems failures from the hazard (fire,wind,
etc).Environmental events like these must be fully understood when planning and designing an MNS,
so the system can clearly and effectively communicate alerts to residents and visitors.The MNS must be
designed to rely on solar power and have enough battery-backup capacity to send critical alerts,when
required, at night, or days when the sun may be blocked by smoke or clouds.
The infamous 2020 wildfires that overtook the northern regions of Los Angeles and Ventura County
exposed the dangers of only relying on web-based or cellular-based emergency alert systems.With over
33 deaths,many of the Cities and Counties have since implemented a radio-based mass notifications
system to mitigate this unnecessary risk in the future.
The City of Rolling Hills contracted with HQE Systems,Inc.(HQE)to develop a comprehensive and
actionable MNS report to enhance its ability to disseminate emergency alerts,especially in wildfire
situations.Since then,HQE has utilized its expertise in Mass Notifications Systems (MNS)to develop
this report to assist The City of Rolling Hills in the pursuit to save lives and protect property.

HQE has studied The City of Rolling Hills’s general and topographic information.These factors will be
taken into careful consideration when developing the final solution options.
3. Report Development Methodology
2.1 Kick-Off Meeting (Clear Project Guidelines)
HQE conducted a project kickoff meeting in October 2020 with The City of Rolling Hills that established
mutual acquaintance,clarified roles,and confirmed the desired outcomes and deliverables.Utilizing its
experience and expertise in MNS,HQE was able to help better understand the constraints of the project
and how HQE could best serve The City of Rolling Hills in achieving its ultimate goal of Saving Lives and
Protecting Property.
2.2 Site Survey (Gathering Information)
HQE conducted a detailed site survey and spent time on-site gathering information to fully understand
the constraints that could impact the system’s operational and technical performances.During the
on-site interview,HQE reviewed each element of an MNS and documented expectations and
requirements of the system.The City of Rolling Hills provided site information based on the current
desires of The City of Rolling Hills and potential pitfalls to consider when planning for the new MNS.
HQE’s analysis began with the initial City provided project considerations to ensure that HQE’s efforts
would be aligned with The City of Rolling Hills’s desires.While on-site,HQE assessed the power options
and locations.In addition,HQE’s sound engineer assessed the residential and commercial building
layouts to determine the best locations of the new MNS points to maximize sound coverage.
2.3 Sound Propagation Analysis (Data-Driven Planning)
HQE conducted a sound propagation analysis to ensure the outdoor emergency alert signal is distributed
optimally throughout The City of Rolling Hills.HQE produced sound propagation maps using site
collected data and HQE’s proprietary outdoor siren planning software to determine the levels of
coverage achieved from potential sites.The coverage models take into consideration varying
geographical topology and environmental factors such as foliage and building density.

4.3.2 The Leading Outdoor Warning Siren System
Outdoor Warning Sirens Reviewed:Intelligible Sound Advantage
Higher intelligibility:High Power Speaker Array ’s (HPSA)’s
vertical line arrays provide a narrow vertical output pattern for
focusing sound at audiences,without wasting output energy on
the floor and up in the air;the more narrow the beam,the less
distortion due to reflections, resulting in higher intelligibility
Equalized intelligibility:HPSA’s vertical line arrays approximate
a line source of sound,creating a nearly cylindrical sound
propagation pattern,resulting in balanced sound power output;
messages are clearly heard at 100 feet as well as 1,500 feet
Directing sound where you need it:HPSA speakers can be
mounted for omni-directional and directional speaker coverage
Intelligibility ratings:0.8 Common Intelligibility Scale (CIS)
rating;Phonetically Balanced Word Score Test—better than
95%*This very high intelligibility rating ensures the clearest
voice alerts.
1.Energy Efficient HPSAs only need one 100-watt driver per horn;two drivers needed for 360°
coverage,equalling a fraction of the number of drivers required for traditional speaker system
designs
2.Better Power Management utilizing Class D amplification technology,the HPSA amplifier is better
than 90%efficient,enables lower current draw and increased battery life,requiring fewer speakers
and significantly less power for a substantially larger range

5. Proposed Solution Options
5.1 Installation Solution Options
HQE has developed the below two (2)options for The City of Rolling Hills’s considerations.Both options
provide the desired intelligible emergency voice alert coverage.
❖Option A:The Low Visibility Installation Option utilizes nine (9)30’poles throughout the City
(see image below).The 30’poles are mounted with the modern designed intelligible speakers.
At 30’,the outdoor warning speakers will be slightly above the height of the residential homes.
This will allow for the best sound transmission without placing the poles too high above the
roofline.In addition,these 30’poles can be covered with tree facades that will blend in with the
local vegetation.
❖Option B:The Low Cost Installation Option utilizes the standard 50’poles mounted with the
intelligible horns positioned in a 360 degree transmission position.The 50’pole allows for the
sound to be projected from a higher elevation.This allows for a greater coverage area which
reduces overall equipment requirements.

6.0 Conclusion of Report
HQE is pleased to conclude this report for The City of Rolling Hills.Although The City of Rolling Hills faces
several challenges that were identified by HQE,the solutions being proposed mitigates all of the
challenges.The report proposes two (2)unique outdoor warning systems installation options for the
City.These options were designed and proposed after careful analysis of the strengths and weaknesses
of all of the current options in the market today.The SiRcom Mass Notifications System allows The City
of Rolling Hills to meet the initial mass alerting requirements and to scale later with any indoor alerting
and security systems integrations that the City may require.This solution being proposed is truly a
capability that will allow The City of Rolling Hills to install a solution that will not be outdated due to the
modern unified mass notifications system design.
The proposed Mass Notifications System is the world’s most comprehensive solution with multiple
redundant alerting channels pre-built into the system.The SiRcom SMART Alert System enables The City
of Rolling Hills to provide the desired emergency response alerting in the event that the power or cellular
communications have failed.It is a Fully Certified Federal Emergency Management Agency (FEMA)
System.The above Unified Mass Notifications System solution ensures that The City of Rolling Hills is
able to maximize the resources available in the mission to Save Lives and Protect Property.The unified
solution doesn’t rely on a single network but a family of networks to ensure that when the Emergency
System is required to perform its purpose, even in the event of power outages, the system WILL WORK!
The proposed solution installed will provide The City of Rolling Hills with the solution to mitigate the risks
faced by the Cities and Counties of California in the infamous 2019 wildfires.In addition to the actual
installation options for the outdoor warning system,HQE would suggest a community outreach program
that would allow the residents of the community to talk directly with Mass Notification Systems experts.
This will allow The City of Rolling Hills to help the residents better understand why the solution is so
important for the life safety program of The City of Rolling Hills.

ROLLING HILLS RESIDENT SURVEY
Improving Our City’s Emergency Preparedness:
The City of Rolling Hills is a rural environment with vegetation and steep hillsides. Due to the
habitat of the environment, the city is susceptible to wildfires, landslides, earthquakes and
the potential for catastrophic damage. Emergency preparedness is one of the most
important things residents can do to make our city safer.
The city is considering investing in more communication products for emergency scenarios:
power outage and loss of cell-phone service. How will residents be notified in an emergency?
What if notifications cannot be sent?
The City recently retained HQE Systems to evaluate the feasibility of installing a siren system
called Mass Notification System. The intent of the siren system is to provide Mass Alerting and
Warning in the event of natural and manmade disasters: wildfires, severe weather,
earthquakes.
The purpose of this survey is to solicit resident feedback on the need/interest of
purchasing outdoor emergency sirens for emergency/evacuation. This evaluation will

March 14, 2022
Dear Honorable Mayor and RH City Councilmembers:
An important priority of the Block Captain program since 2019 is Emergency Communications.
How will residents be notified of an emergency evacuation? Will notification be limited to people
who pre-register to receive emergency alerts? What happens in the event of no electricity or
phone service?
We support the RH City Council to approve the installation of an outdoor siren system by HQE
Systems to notify residents in the event of an emergency. This important safety measure will
help ensure that all our residents who live in Rolling Hills, a designated high-fire severity zone,
can be notified when there is no electricity or internet service. Many residents support the cost
investment necessary to install and maintain either three or nine poles necessary for coverage
of Rolling Hills; we understand Federal and State grant funds are available for cities, especially
those cities designated as high-fire severity zones.
Safety of all our residents is directly dependent on reliable emergency notifications to residents.
LA County Fire Department have stated that given the close proximity to a potential wildfire
starting on the peninsula, residents in Rolling Hills would not have the benefit of an evacuation
alert or warning; residents would likely be asked to evacuate immediately. Thus, we support
having an emergency plan that considers all potential scenarios, including a worst-case one.

Dear Mr. Palermo.
This is normal actually. We are very famiar with SCE and other utility companies
requirements when it comes to outdoor warning sirens. Bottom line upfront, none of the
sirens installed will violate any compliance policies or agreements. At this feasibility phase
that information is not detailed out. That level of detail is only clarified and planned out during
the "Design Phase" of an outdoor warning siren project.
The proposed outdoor warning sirens locations identified on the sound propagation map and
or images are proposed general areas for review. The final install points will take into
consideration not just SCE's policies but the City's actual approval of that specified site (may
require a slight location change based on the residents' input and the Board's final decision),
soil suitability, wind assessment, religious/historic site survey, and general geological studies
to ensure the install and maintenance efforts can be performed without significant distrubance
of the site. Which are all detailed out in the Design Phase. The key issue to take away is that
this outdoor warning sirens report is enable the City to determine the ideal install types of the
sirens and the general understanding of the coverage install plan. Based on that final decision
for approval for installation, a detailed POA&M will be provided with the design installation
plans that will meet all compliance requirements. At this phase of the project, HQE is
providing the information that highlights the importance of the outdoor warning sirens for life
safety plans for the City and and the options that would be available to the City.
Please let me know if any other questions can be answered.

Jamie,
The City shared your latest information with SCE. SCE replied, see below.
I let the City know your document is not a final plan but just a more detailed proposed
layout/street level views to comply with a request from City Council. Final plans should the
city proceed with this project would be required to take into account all existing
titles/conflicts.
Is there any other response/information on SCE’s comment I can pass along to the City?
Thanks.

Elaine and City Council:I will be there at 7 but must leave by 7:50 for a zoom mtg
at home. I think the issue re new safety equipment blocking views etc. is easily
solvable. To start put siren equipment including cameras on top of the flagpoles at
the 3 gates plus a giant pole (RPV has a communication tower that is extendable
in a disaster) just outside the Crest East gate on property the City owns. It’s
camera could see the whole peninsula! There are other locations where no one’s
views would be materially affected including on slim neutral color metal poles in
canyons or on top of telephone poles like at Crest and PBRd. I would be willing
to have a camera on my home eves that would see the entire area facing the
Pacific. Plus a siren if requested. Thanks. Don

Good morning Arlene,
I think that an emergency notification system is a good idea, but I have several questions about
the HQE system.
1) Will it have the capability to give verbal information after the siren? A siren will certainly
cause panic, and we would need to have accurate info and directions.
2) Who will be responsible for sounding the siren and disseminating the information?
3) Where will the poles be placed, and will they be camouflaged to look like a pine tree?
4) Have other cities used HQE?
Thank you!
Nancy

For those who need more information I am happy to send the Feasibility Study by
HQE Systems, which includes the potential locations of poles (3 poles and 9
poles), pole types, and other information. The siren study was initiated to see
what options are available for the city when there is no electricity or cell phone
service, that is, a worst case scenario.
Remember, if you are not in favor please voice or send a letter with your concerns
to the City Council...it is important they hear from us on this important issue.

Dear Block Captains and Block Captain Support Team,
On Monday, March 14 the City Council will discuss an outdoor siren system by
HQE Systems. This outdoor siren system will provide emergency
communications to residents, even when there is no electricity or no cell phone
service.
The feasibility study was completed and the study includes 2 options: one with
the installation of nine poles (30 feet) for $310,600 and one for the installation of
three poles (50 feet) for $144,575.
We have prepared a letter to the City Council stating our support to move forward
with the installation of this outdoor siren system. Please let me know if you
would like to add your name to the letter (below). We need your approval
for this important priority. Reply by Monday morning and your email reply
will serve as a signature.
You are welcome to send in your own letter to the RH City Clerk and attend the
City Council meeting. Remember, let your opinion be heard.

Dear Honorable Mayor and RH City Councilmembers:
An important priority of the Block Captain program since 2019 is Emergency
Communications. How will residents be notified of an emergency evacuation?
Will notification be limited to people who pre-register to receive emergency
alerts? What happens in the event of no electricity or phone service?
We support the RH City Council to approve the installation of an outdoor siren
system by HQE Systems to notify residents in the event of an emergency. This
important safety measure will help ensure that all our residents who live in
Rolling Hills, a designated high-fire severity zone, can be notified when there is
163
no electricity or internet service. Many residents support the cost investment
necessary to install and maintain either three or nine poles necessary for
coverage of Rolling Hills; we understand Federal and State grant funds are
available for cities, especially those cities designated as high-fire severity
zones.
Safety of all our residents is directly dependent on reliable emergency
notifications to residents. LA County Fire Department have stated that given
the close proximity to a potential wildfire starting on the peninsula, residents in
Rolling Hills would not have the benefit of an evacuation alert or warning;
residents would likely be asked to evacuate immediately. Thus, we support
having an emergency plan that considers all potential scenarios, including a
worst-case one.

Agenda Item No.: 12.B
Mtg. Date: 03/28/2022
TO:HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM:CHRISTIAN HORVATH,
THRU:ELAINE JENG P.E., CITY MANAGER
SUBJECT:APPROVE PRIORITIES/GOALS FOR FISCAL YEARS 2022-2023 AND
2023-2024 DEVELOPED AS A PART OF THE 2022 STRATEGIC
PLANNING WORKSHOP; DISCUSS POTENTIAL BUDGET ITEMS TO
SUPPORT THE 2022 CITY COUNCIL PRIORITIES; AND PROVIDE
DIRECTION TO STAFF.
DATE:March 28, 2022
BACKGROUND:
On Saturday, January 22, 2022, the City Council held a bi-annual Strategic Planning Session
facilitated by City Manager. Staff summarized the workshop and presented a summary of the
priorities and goals the City Council set for the next two fiscal years (FY 2022-2023 and 2023-
2024) at the February 14, 2022 City Council meeting. The City Council reviewed the
summary, expressed concurrence with the summarized priorities/goals and directed staff to
make the following additions to the summary:
Add "Consider wildfire cameras" to the Wildfire Mitigation/Emergency Preparedness
Evacuation priority.
Add the capital improvement projects discussed at the January 22, 2022 Strategic
Planning Workshop. At the workshop, the City Council discussed two capital projects:
Tennis Courts ADA Improvements and City Hall ADA Improvements.
The revised summary of priorities/goals is attached to this report. It was also discussed at the
February 14, 2022 City Council meeting that staff will be utilizing the final summary of
priorities/goals to develop budget items for the upcoming Fiscal Year 2022-2023.
DISCUSSION:
The following briefly describes the proposed budget items for Fiscal Year 2022-2023:
Wildfire Mitigation/Emergency Preparedness
Proposed budget items include allocations to the Block Captain Program, fire fuel reduction in
the Preserve in the areas closest to the border of Rolling Hills, and consultant to support the
enforcement of dead vegetation abatement ordinance and other ordinances relating to fire fuel
167
abatement for a total of $163,000.
Utility Undergrounding
Proposed budget items include allocations for the two CalOES/FEMA grant projects to
underground utility lines along Crest Road East and Eastfield Drive. The City's Rule 20A Tariff
balance will be used as match funds to the grant projects, totaling $1,041,000. Proposed
budget items for this priority also included a budget of $15,000 to support residents that want
to form assessment districts to underground utility lines in the community.
Capital Improvement Projects
The estimated construction cost for the Tennis Courts ADA Improvements was $350,000 in
2018. An approximate fifteen percent cost escalation was added to the estimate from 2018 to
characterize the anticipated construction cost of the Tennis Courts ADA Improvements at
$400,000. The latest estimated construction cost for the City Hall ADA Improvements was
$1,000,000. The City Council is still considering layout options for the project and the cost of
construction could increase depending on the ultimate layout selection. In total, the proposed
budget for this priority is approximately $1,400,000. Staff is inquiring if the American Rescue
Plan Act (ARPA) allocation of $441,000 is eligible for infrastructure improvement at City Hall.
The final ARPA regulations listed water, sewer and broadband infrastructure as eligible
expenses. There would be a significant General Fund offset if the ARAP allocation can be
used for the City Hall ADA Improvements project.
Drainage
The proposed budget items for this priority include storm water monitoring to demonstrate to
the Los Angeles Regional Water Quality Control Board that the City is retaining the design
storm, investigate provisions on the land development side to retain additional storm water on
private property, and research ownership/agreements with Los Angeles County on
maintenance and operation responsibilities for a total of $54,000.
Communication with residents
The proposed budget items for this priority includes outsourcing the production of the Blue
Newsletter, on-going technical support for the Emergency Information System/Trading Post,
and on-going subscription to Everbridge (Alert South Bay) and E-Notify for a total of $30,000.
City personnel recruitment/retention plan
The proposed budget items for this priority includes hiring a human resources professional for
personnel support, and increase city contribution to employees medical/dental/vision coverage
for a total of $26,000.
Expand resident services
The proposed budget items for this priority include summer outdoor movie nights at the City
Hall campus and providing a notary at City Hall one day per month to residents for a total of
$7,000.
Sewer
The proposed budget item for this priority includes hiring a grant writer to secure construction
funds for the 8" sewer main along Rolling Hills Road/Portuguese Bend Road for $15,000.
The proposed budget items to support the City Council's priorities/goals for Fiscal Year 2022-
2023 total $2,751,000 with Rule 20A Tariff and $1,695,000 without Rule 20A Tariff (General
168
Fund only).
FISCAL IMPACT:
The 2022 strategic planning workshop was facilitated by staff. There was no fiscal impact to
conducting the workshop. Depending on the direction to staff, the proposed budget items will
be incorporated in the budget preparation for Fiscal Year 2022-2023.
RECOMMENDATION:
Approve priorities and goals; discuss potential budget items and provide direction to staff.

2022 CITY COUNCIL STRATEGIC PLANNING WORKSHOP
CITY COUNCIL’S REVIEW AND DISCUSSION OF THE 2020 ESTABLISHED
PRIORITIES/GOALS
2020 Established Priorities and Goals 2022 Council Comments on 2020 Priorities and Goals
1 Sewer The City Council stated that the cost of sewer installation is cost
prohibitive given the available general funds to construct the 8”
main line. One Councilmember expressed that this priority
should be moved to the bottom of the list for the next two years
pending availability of grant funds. Another Councilmember
expressed that this priority should be entirely removed from the
list. The City Council expressed consensus for staff to pursue
grant funds to install the sewer lines. There was no discussion
on the current activities relating to this priority and whether if
the activities should be abandoned or continued (preparation of
8” sewer main).
2 Wildfire/Emergency Preparedness The City Council expressed consensus that the activities, actions,
and pursuits on the wildfire mitigation and emergency
preparedness front were good and should continue. Individual
Council members provided input on aspects of this priority (i.e.,
balance between cost and fire fuel abatement) but there was
not consensus on the actions items relating to those input.
3 Utility Undergrounding The City Council expressed consensus that the Crest Road East
Utility Undergrounding grant project, and the Eastfied Drive
Utility Undergrounding grant project – if awarded, should be the
focus on fulfilling this priority.
4 Drainage The City Council expressed consensus that the work to date on
finding alternative compliance solutions to the MS4 permit
should continue, including retaining more stormwater discharge
on private property. On drainage issues in the community
172
2
(erosion, and unclaimed drains accepting stormwater discharges
from easement areas), majority of the Council expressed the
need to investigate to find out the City’s obligations on this
front. Investigation includes research into the ownership of the
drains accepting flow from easement areas of the community.
Investigation includes identify the responsible party for
maintaining and operating the drains accepting flow from
easement areas of the community. One Councilmember
expressed opposing views on the investigation needed but later
agreed to it if the amount of staff time spent on the
investigation was minimal.
A. Ease permit process – no action identified in 2020 Remove from list.
B. Communication with residents – keep blue newsletter.
Periodically increase content. Come back with costs regarding
outsourcing.
The City Council recognized that the blue newsletter is a popular
item and expressed that the contents should continue to be
povided by staff but that the production of the newsletter can
be contracted out to eliminate tedious manual labor for a small
staff.
C. Shorter council meetings – have staff bring the City Council back
to focus to keep meeting moving forward.
The City Council expressed that this item should be removed
from the priority/goal list for the next two Fiscal Years.
D. Minimize legal liability – Support ADA project to decrease
potential liabilities. Staff to define and narrow breadth of legal
inquiries.
The City Council discussed that inherent to the city operations,
minimize legal liability is a core function of the city and therefore
does not need to be listed as a priority/goal.
E. Public Safety – Use advocacy to promote safety, if needed City
Council will exercise more authority in the future. Ensure armed
school resource officer is armed as a provision of contract.
As with the item on minimize legal liability, the City Council
discussed that public safety is an obligation of the city and
therefore does not need to be listed as a priority/goal.
F. Reinstate view ordinance – Support waiting for outcome of
current complaints before changing current process.
A member of the City Council expressed that only one case has
been processed with the current view case and that the City
should collect more experience with the current view ordinance
before changes are implemented. Another member of the City
Council expressed that the fee on view application ($2,000 per
application for case against unlimited properties) is insufficient
for cost recovery and the fee should be increased. There was no
consensus among the City Council to change the current view
ordinance.
173
3
G. Purchase property for open space – not acquire The City Council agreed to eliminate this item as a priority/goal
due to the Surplus Land Act.
H. Refund the residents – staff coming back with recommendations
on how to spend surplus: services, drainage, firebreak, etc.
Come back after fiscal year. City Council committing money
TBD.
Staff recommended that the City Council hold community events
such as outdoor moving nights at the City Hall campus during
the summer time. The City Council expressed consensus to fund
community events. There was also consensus among the
Council that surplus should not be used to refund the residents
but the surplus funds should be used to provide more services to
the residents. With the capital improvement backlog, there was
discussion that there would no surplus until after all the capital
improvements were completed.

SUBJECT:APPEAL OF COMMITTEE ON TREES AND VIEWS' DECISION ON VIEW
PRESERVATION COMPLAINT - 61 EASTFIELD DRIVE (JUGE -
COMPLAINANT) AND 59 EASTFIELD DRIVE (TAMAYO/SIERRA -
VEGETATION OWNER)
DATE:March 28, 2022
BACKGROUND:
On September 4, 2019, the City received a View Preservation Application from Mr. Joseph
Juge at 61 Eastfield Drive (Complainant) regarding vegetation located on Mr. Julio Sierra and
Dr. Beatriz Tamayo's property at 59 Eastfield Drive (Vegetation Owners). The application was
found to be insufficient because the parties had not gone through initial reconciliation and
mediation as described in Rolling Hills Municipal Code (RHMC) Section 17.26.040.
On October 28, 2020, Mr. Juge filed another application requesting review by the Committee
on Trees and Views (CTV). The application included correspondences showing initial
reconciliation and meditation were attempted, which continued until October 9, 2020, when the
Vegetation owners asked about the responsibility for the mediator's fee. Records show that
the Complainant never responded to the question, thus ending all communication between the
two parties. Complainant claimed that he met the requirements of the Municipal Code because
the mediation phase exceeded the 60-day period. Per the Municipal Code, the Complainant
may proceed to an advisory hearing before the CTV if the Vegetation Owners fail to respond
within 60 days. In this case, the Vegetation Owners responded to the request for mediation,
however, the Complainant stopped communicating. Based on this action, the mediation phase
was not completed.
On June 1, 2021, staff informed the CTV on the actions that had taken place. The parties were
advised to continue and complete the mediation phase with the caveat for an end date.
On August 17, 2021, staff reported to the CTV that both parties had not settled on a mediator
and a new deadline was set for October 5, 2021.
On September 1, 2021, the Vegetation Owners emailed the Complainant and copied staff that
177
they have decided to withdraw their intention to mediate.
On October 5, 2021, November 2, 2021, November 3, 2021 (site visit), November 9, 2021,
and November 16, 2021, the CTV held meetings to discuss the application. Ultimately, it was
decided that an arborist be selected to provide an evaluation of the vegetation.
On November 17, 2021, the Complainant sent the City a list of four arborists. The City
contacted all four, but only one responded, Mr. Gregory MacDonald. Mr. MacDonald was
ultimately retained after both parties agreed to his services.
On November 30, 2021, at 10:00 a.m., the arborist conducted a site inspection at both
properties and prepared a written report for tree maintenance and restoration that was
presented to the CTV at its evening meeting on November 30, 2021 at 5:30 p.m. At the
evening meeting, the CTV adopted Resolution No. 2021-21-CTV advising on the view
preservation dispute. The Committee made several recommendations for restorative actions
and preventative measures, which are described in Resolution No. 2021-21-CTV.
On January 27, 2022, the City received an appeal of Resolution No. 2021-21-CTV from the
Vegetation Owners' attorney, Mr. Edgar Coronado.
DISCUSSION:
Pursuant to RHMC Section 17.25.040.D, if either party is not satisfied by the
recommendations of the CTV, said party may request a public hearing before the City Council
to review the decision of the CTV. The City Council shall be guided by the evaluation criteria
set forth in Section 17.26.050, and the heirarchy of restorative actions set forth in Section
17.26.060.
17.26.050 - Considerations for applying the view preservation ordinance.
A . The following nonexclusive factors, for which the parties can prove by a preponderance of
the evidence, are to be considered in determining whether a pre-existing view has been
obstructed:
1. The viewing point(s) from which the view is observed;
2. The extent of the view obstruction, both currently and at the maximum height the
tree/vegetation is likely to reach (as described by the most current edition of the New
Sunset Western Garden Book);
3. The quality of the view, including the existence of landmarks, vistas, or other unique view
features;
4. The extent to which trees and/or vegetation have grown to obscure the enjoyment of the
view from the claimant's property since the claimant acquired his/her property;
5. The extent to which the vegetation on the property preserves privacy (visual and
auditory), wind screening, energy conservation, and/or climate control;
6. The extent to which the vegetation owner can establish the earliest known date when the
complained of vegetation was planted or existed on the vegetation owner's real property;
and
7. The degree to which the complainant diligently tried to protect and maintain their view
through informal agreements with the vegetation owner or prior vegetation owner(s) and
to initiate initial discussions with the current vegetation owner; and the degree to which
the current vegetation owner has reasonably participated in initial discussions.
B . The following applicable, nonexclusive factors, for which the parties can prove by a
178
preponderance of the evidence, may be considered in determining the appropriate restorative
action, if any is necessary:
1. The variety of tree, its projected rate of growth (as described by the most current edition
of the New Sunset Western Garden Book) and maintenance requirements;
2. The aesthetic quality of the tree(s), including but not limited to species characteristics,
size, growth, form and vigor;
3. Location with respect to overall appearance, design or use of the tree on the vegetation
owner's property, including, but not limited to blending, buffering, or reduction in the
scale or mass of a structure;
4. Soil stability provided by the tree(s), considering soil structure, degree of slope and
extent of the tree's root system;
5. The extent to which the vegetation owner can establish the earliest known date when the
complained of vegetation was planted or existed on the vegetation owner's real property;
6. Privacy (visual and auditory) and wind screening provided by the tree(s) to the tree
owner and to neighbors;
7. Energy conservation, shade and/or climate control provided by the trees;
8. Wildlife habitat provided by the trees.
17.26.060 - Restorative action.
A. Restorative actions may include, but are not limited to, the following, in order of preference,
assuming no countervailing health or safety interest(s) exist:
1. Lacing. Lacing is the most preferable pruning technique that removes excess foliage and
can improve the structure of the tree.
2. Crown Raising.
3. Crown Reduction. Crown reduction is preferable to tree removal, if it is determined that
the impact of crown reduction does not destroy the visual proportions of the tree,
adversely affect the tree's growth pattern or health, or otherwise constitute a detriment to
the tree(s) in question.
4. Heading Back. Heading back is only to be permitted for trees specifically planted and
maintained as a hedge, espalier, bonsai, or in pollard form and if restoration actions in
subsections (A) through (C) of this section will not accomplish the determined
preservation action and the subsequent growth characteristics will not create a future
obstruction of greater proportions.
5. Topping. Topping is only to be permitted for trees/vegetation species for which it is
appropriate.
6. Removal. Removal may be considered when the above-mentioned restoration actions
are judged to be ineffective and may be accompanied by replacement plantings or
appropriate plant materials to restore the maximum benefits lost due to vegetation
removal.
B . Restorative action shall include written conditions (including ongoing maintenance),
directions, and a schedule by which the mandates must be completed, and may be made to
run with the land and apply to successors in interest. The complainant may bear the cost of
the initial restorative action, unless the parties agree to share the costs in some other manner.
Subsequent maintenance of the vegetation in question may be performed at the cost and
expense of the owner of the property on which the vegetation is growing, unless otherwise
agreed to by the parties or required pursuant to any final arbitration agreement or court order.
The vegetation shall be maintained so as not to allow for future view impairments.
179
C . In cases where restorative action may affect the health of a tree, such actions should be
carried out in accordance with standards established by the International Society of
Arboriculture for use in the State of California. Severe pruning (heading back and/or topping)
should be avoided due to the damage such practice causes to the vegetation's form and
health. Where removal is required, replacement by appropriate species should be considered.
FISCAL IMPACT:
None.
RECOMMENDATION:
Consider the appeal and provide direction to staff.

SUBJECT:VIEW PRESERVATION COMPLAINT - 61 EASTFIELD DRIVE (JUGE -
COMPLAINANT) AND 59 EASTFIELD DRIVE (TAMAYO/SIERRA -
VEGETATION OWNER)
DATE:November 30, 2021
BACKGROUND:
At the Committee on Trees and Views teleconference meeting on November 16, 2021, The Committee
continued the meeting until November 30, 2021 at 5:30 p.m. This would give the City more time to
select an arborist that was affordable for the Complainant, meet the City's requirements and
certifications, and Vegetation Owners' approval.
On November 17, 2021, Joe Juge (Complainant) sent the City a list of 4 arborists. The City contacted all
four arborists, and only one arborist responded, Mr. Gregory MacDonald.
On November 22, 2021, Gregory MacDonald (Arborist) provided the City with his qualifications and
proposal.
On November 22, 2021, City Staff reviewed Gregory MacDonald's certifications and qualifications.
Staff determined he met all of the City's requirements and certifications.
On November 22, 2021, Joe Juge (Complainant) agreed to the Arborist rate of $120 per hour for
services and 12% required City Administrative fee of the total cost of arborist services.
On November 24, 2021, Dr. Tamayo and Mr. Sierra (Vegetation Owners) reviewed all of the Arborist
information and approved Gregory MacDonald to serve as the arborist. They also agreed to grant the
arborist access to their property, with the request that a 48 notice is provided before he enters onto their
property. The Vegetation Owner's requested the inspection be scheduled on either Tuesdays or
Thursdays. It was also requested that the arborist understand the view preservation standards provided
by the RHMC before any recommendations are made.
On November 24, 2021, Mr. Joe Juge came into the City to pay the arborist fees a total of $480 ($120
per hour) and $57 (12% required City Administrative fee).
1254
On November 29, 2021, the City will enter into a contract agreement with Gregory MacDonald to
provide arborist services. The arborist and Complainant will enter into a contract agreement for services.
On November 30, 2021 at 10:00 a.m., the arborist will conduct site inspections at 61 Eastfield Drive
(Complainant) and 59 Eastfield Drive (Vegetation Owners) and prepare a written report for tree
maintenance and restoration that will be presented at the Committee on Trees and Views evening
meeting on November 30, 2021 at 5:30 p.m. The arborist's recommendations, along with the
Committees' recommendations will be included into the resolution that will be drafted by Staff.
DISCUSSION:
This meeting is a continuation of the Committee on Trees and Views virtual meeting held on November
16, 2021 at 5:30 p.m.
FISCAL IMPACT:
None.
RECOMMENDATION:
Direct Staff to prepare a resolution.

ARBORIST REPORT for
61 Eastfield Drive, Rolling Hills, CA - View restoration
On November 30, 2021, I, Gregory MacDonald, Certified Arborist #WE 6469A did a site visit
to assess recommendations for view restoration. There are a number of trees and some shrubs
involved. Starting from the far left of the view issue, there is a Toyon shrub that should be fine
with some reduction trimming up to 25% of foliage. It could possibly be trimmed lower at the
next years trimming if it responds well to the first trim.
Much lower on the slope, there is an apparently fully dead Eucalyptus that should be
removed down to near ground level. It may or may not be a view issue but as a course of
regular maintenance and safety needs to be addressed. The entire root system should probably
be left in place to not disturb the slope.
The large ash tree appears to be 60 + years old and in less than great health. It has dieback
typical of drought stress but should not be adversely affected by the recommended reduction
and lacing. As a deciduous tree, it has systems in place to deal with foliage loss. I would add the
need for crown cleaning to remove all completely dead branches.
The two relatively young Canary Island Pine Trees should do fine with crown reduction
trimming to an appropriate side branch/whorl. I would advise not removing more than 30% of
the foliage at this time. If possible, the side branches should not be cut at this time but could
possible be reduced in following years. This action will completely change the natural form of
these two trees, but if follow-up trimming is done with care, they can be good shade and slope
stabilizing trees.
The Avocado appears to be in decline and needs no trimming.
The large Pepper tree was recommended to be reduced to the roofline of the adjacent
structure. This tree has well developed branching, so this should be fine if reduction cuts are
used and no topping cuts are done. The request to remove the large trunk growing over the
pathway down towards the pool house is not recommended. I feel it would be far better
reduced both vertically at the end as well as laterally. This would reduce the weight out to the
side. The tree has survived being cut significantly at the base (many years ago) and I would not
suggest adding to that by removing a trunk of the tree. I would advise against cuts larger than
4” diameter as Schinus molle are not known to compartmentalize decay very well.
The Loquat tree close to the structure should be fine with crown reduction trimming. It too,
has well developed branching that allows for smaller cuts.
The pomegranate tree will do fine with reduction trimming. As a deciduous tree, it has
systems in place to deal with foliage loss.
3256
The Oleander hedge is suffering from “Oleander Leaf Scorch” also called “Bacterial Leaf Scorch”
(BLS) and there is no known cure. It is possible to prolong the life of these shrubs with
additional watering, and I strongly recommend adding a drip irrigation system. If screening and
sound reduction are the goal, I would suggest interplanting with True Bay, Wax leaf Privet, or
Australian Brush Cherry. They can be planted in between the existing Oleanders and as the
Oleander continue to die, the new shrubs can take over the role of a hedge. The insect that
carries the bacterial disease (Xylella fastidiosa), gets the bacteria by feeding on diseased shrubs
and trees, so removal of these diseased shrubs may be a consideration. Once infected, the
shrubs slowly lose the ability to transport water through their Xylem to other parts of the
shrub. Trimming this hedge at the roof line should be fine.
The Schefflera shrub can be reduced in height one branch at a time with a lower risk of
damage to it.
An inspection and Arborist Report with recommendations do not in any way give or imply any
warrantee against tree or limb failures. Trees and their limbs can and do fail. No inspection can
prevent that, and recommendations given here are simply given as options to consider. Every
tree can react differently to trimming, climate, soil conditions, and watering. Any action taken
are the responsibility of the property owner and the company doing the physical work.
I thank you for the opportunity to be of help with these trees,

Mtg. Date: 03/28/2022
TO:HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM:JOHN SIGNO, DIRECTOR OF PLANNING & COMMUNITY SERVICES
THRU:ELAINE JENG P.E., CITY MANAGER
SUBJECT:CONSIDER AND APPROVE RESOLUTION NO. 1291 OF THE CITY
COUNCIL OF THE CITY OF ROLLING HILLS ADOPTING THE SAFETY
ELEMENT UPDATE AND A NEGATIVE DECLARATION FOR THE
SAFETY ELEMENT
DATE:March 28, 2022
BACKGROUND:
This item was continued from the March 14, 2022 City Council meeting.
The City began its efforts to update the Safety Element in mid-2020 after being awarded
funding from the Governor's Office of Emergency Services (CalOES). The City obtained the
professional services of Rincon Consultants, Inc. to prepare the Safety Element. Once
completed, the Safety Element was sent to the California Board of Forestry and Fire
Protection for review, but no recommendations or changes were made.
On January 18, 2022, a presentation on the Safety Element was made to the Planning
Commission. The presentation provided an overview on new legislation, policies, and topics
included in the Safety Element. On February 15, 2022, the Planning Commission held a public
hearing and recommended unanimously that the City Council adopt the Safety Element
Update.
DISCUSSION:
Since the March 14, 2022 City Council meeting, the negative declaration has been bifurcated
and an errata has been prepared to: (1) show the changes made to the draft negative
declaration to remove the Housing Element as part of the Project; and (2) explain why
recirculation under CEQA Guidelines Section 15088.5 is not triggered (i.e., not a substantial
revision).
Originally, s taff intended the Safety Element to be considered at the same time as the Housing
Element. However, the City cannot adopt the Housing Element until it receives and considers
comments from HCD. The City sent the Housing Element to HCD for review on January 11,
2022. HCD now has 90 days, or by April 11, 2022, to submit its comments to the City. Since
278
the Housing Element is not ready for adoption, staff is moving forward with the Safety Element
separately since it still must report to CalOES on the progress in order to receive funding
reimbursement. The grant completion date is currently May 9, 2022, however, staff has
requested an extension from CalOES because there is a 45-day review period by CalOES and
a 30-day close-out period to receive reimbursement. An item is included in the March 28, 2022
agenda to inform Council of the requested time extension to July 15, 2022.
The Safety Element provides the City of Roll ing Hills’ (City’s) goals, policies, and actions to
minimize the hazards to safety in and around Rolling Hills. It evaluates natural and human-
caused safety hazards that affect existing and future development and provides guidelines for
protecting the community from harm. It describes existing and potential future conditions and
sets policies for improved public safety. The goal is to reduce the risk of injury, death, property
loss, and other hardships to acceptable levels. It is required to be reviewed and updated as
necessary to address the risk of fire for land classified as state responsibility areas and land
classified as very high fire hazard severity zones (Gov. Code, § 65302(g)(3)). It is required to
include:
Fire hazard severity zone maps available from the Department of Forestry and Fire
Protection.
Any historical data on wildfires available from local agencies or a reference to where the
data can be found.
Information about wildfire hazard areas that may be available from the United States
Geological Survey.
The general location and distribution of existing and planned uses of land in very high fire
hazard severity zones (VHFHSZs) and in state responsibility areas (SRAs), including
structures, roads, utilities, and essential public facilities.
The location and distribution of planned uses of land shall not require defensible space
compliance measures required by state law or local ordinance to occur on publicly
owned lands or open space designations of homeowner associations.
The local, state, and federal agencies with responsibility for fire protection, including
special districts and local offices of emergency services (Gov. Code, § 65302(g)(3)(A)).
Based on that information, the Safety Element shall include goals, policies, and objectives that
protect the community from the unreasonable risk of wildfire. (Gov. Code, § 65302(g)(3)(B)).
To carry out those goals, policies, and objectives, feasible implementation measures shall be
included in the Safety Element, which include but are not limited to:
Avoiding or minimizing the wildfire hazards associated with new uses of land.
Locating, when feasible, new essential public facilities outside of high fire risk areas,
including, but not limited to, hospitals and health care facilities, emergency shelters,
emergency command centers, and emergency communications facilities, or identifying
construction methods or other methods to minimize damage if these facilities are located
in the SRA or VHFHSZ.
Designing adequate infrastructure if a new development is located in the SRA or
VHFHSZ, including safe access for emergency response vehicles, visible street signs,
and water supplies for structural fire suppression.
Working cooperatively with public agencies with responsibility for fire protection (Gov.
Code, § 65302(g)(3)(C)).
279
The Safety Element shall also attach or reference any fire safety plans or other documents
adopted by the City that fulfill the goals and objectives or contains the information required
above (Gov. Code, § 65302(g)(3)(D)). This might include Local Hazard Mitigation Plans, Unit
Fire Plans, Community Wildfire Protection Plans, or other plans.
FISCAL IMPACT:
The City obtained a grant from CalOES for $47,624 to update the Safety Element. The City is
committed to providing $15,875 in local match (General Fund) to meet the total project cost of
$63,499. As of the end of 2021, the City spent $53,115.50 in consultant and administrative
costs. Certification of the Element provides an indirect positive fiscal impact by reducing legal
risks and qualifying the City for State planning grants.
RECOMMENDATION:
Approve Resolution No. 1291 adopting the Safety Element update and a negative declaration
for the Safety Element.

Introduction
Safety Element 1
Introduction
The Safety Element provides the City of
Rolling Hills’ (City’s) goals, policies, and
actions to minimize the hazards to safety in
and around Rolling Hills. The Element
evaluates natural and human-caused safety
hazards that affect existing and future
development and provides guidelines for
protecting the community from harm. The
Element describes existing and potential
future conditions and sets policies for
improved public safety. The goal of the Safety
Element is to reduce the risk of injury, death,
property loss, and other hardships to
acceptable levels.
City Setting
Rolling Hills covers an area of approximately
three square-miles on the Palos Verdes
peninsula, approximately 18 miles south of
downtown Los Angeles. The topography of
the city and peninsula area is unique in that it
rises above the Los Angeles Basin with rolling
hills, steep slopes, and canyons. The city itself
is in the San Pedro Hills. Due to its location
near the coast, the area is generally cooler
and has fewer air quality concerns compared
to the nearby Los Angeles Basin. Table 1
summarizes the climatology of the area.
Rolling Hills City Hall
Rolling Hills is a residential community that
consists of large parcels and ranch-style
homes and has a sizable older adult1
population of about 513 (28% of the city’s
total population). Important community
demographic data for Rolling Hills is included
in Table 2. The city is also an equestrian
community, as many of residents are horse
owners or have horses on their property.
Regulatory Setting
Section 65302(g) of the California
Government Code requires that the General
Plans include a Safety Element for the
protection of the community from any
unreasonable risks associated with the effects
of seismically induced surface rupture,
ground shaking, ground failure, tsunami,

seiche, and dam failure; slope instability
leading to mudslides and landslides;
subsidence and other geologic hazards;
flooding, and wildland and urban fire. In
addition, Safety Elements are required to
address non-hazard specific issues such as
peak load water supply, evacuation routes,
and military installations.
Senate Bill 379, adopted on October 8, 2015,
requires cities to include climate change
adaptation and resilience into the general
plan process. To comply with SB 379, this
Safety Element includes a vulnerability
assessment; adaptation and resilience goals,
polices, and objectives; and feasible
implementation measures.
Senate Bill 99, adopted August 30, 2020,
requires the cities to “identify residential
developments in any hazard area identified in
the safety element that does not have at least
two emergency evacuation routes.” SB 99
does not define neighborhood and cities are
expected to define neighborhoods based on
their community.
Relationship to Other Documents
The Rolling Hills Safety Element is one of
several plans that address safety in the City.
The Safety Element must be consistent with
these other plans to ensure the City has a
unified strategy to address safety issues. The
Safety Element includes information and
policies from the following documents to
ensure consistency.
Other General Plan Elements
The Safety Element is one section of the
Rolling Hills General Plan. Other elements
include Land Use, Transportation, Housing,
285
Introduction
Safety Element 3
Conservation, Open Space and Recreation
and Noise. Policies in these other elements
may be related to safety issues. Information
and policies in the Safety Element should not
conflict with those in other elements.
Hazard Mitigation Plan
The City’s Hazard Mitigation Plan includes
resources and information to assist the City of
Rolling Hills, its residents, and public and
private sector organizations in planning for
hazard events. The Plan provides a list of
activities that may assist the City in reducing
risk and preventing loss from future hazard
events. The action items address multi-hazard
issues, as well as activities specifically for
reducing risk and preventing losses relating to
earthquake, land movement, wildfire, and
drought.
Community Wildfire Protection Plan
The City’s Community Wildfire Protection
Plan (CWPP), adopted in July 2020, seeks to
reduce wildfire risk in Rolling Hills. The Plan
was developed collaboratively among
stakeholders including the community, the
City of Rolling Hills, the Rolling Hills
Community Association, and the Los Angeles
County Fire Department, and the Los Angeles
Sheriff’s Department. The Plan includes fire
mitigation and evacuation strategies for the
community.
Critical Facilities and
Infrastructure
Critical facilities are places that provide
emergency services or serve people who
would be impacted by an emergency.
Examples include hospitals, fire stations,
police stations, emergency services facilities,
utility facilities, and communication facilities.
Critical facilities can also include the
transportation system and schools. Due to
the size and composition of Rolling Hills,
many of the critical facilities that serve the
city are located outside of city limits. No areas
in Rolling Hills have been identified as lacking
emergency service. Critical facilities that serve
the city are shown in Figure 1 and include:

Hazards of Concern
Geologic Hazards
Geologic processes that pose a threat to life,
health, property, or infrastructure are
considered geologic hazards. Natural geologic
hazards that have the potential to affect
Rolling Hills include seismic hazards,
landslides, liquefaction, expansive soils, and
weathering. In most cases, these natural
processes cannot be prevented; however, the
magnitude of destruction resulting from
natural geologic hazards can be reduced
through planning policies and measures.
Landslide Hazards
Landslide activity refers to a wide range of
gravity driven downslope earth movement,
including rockslides, rotational slips,
mudslides, and shallow debris flows.
Geological and geomorphological conditions
such as soil type, soil strength, slope angle,
and slope height predispose slopes for failure.
Other factors affecting the susceptibility to
slope failure include the amount of
precipitation, vegetation on the slope,
groundwater seepage, and human
modifications to the slope. Landslides often
result in damage to property and roadways
and can cause them to become unsafe due to
displacement of the subsurface.
Much of the existing development in Rolling
Hills is located on hilly terrain and have a
greater potential to experience landslide
hazards. Many of the canyons in Rolling Hills
exhibit steep slopes with little vegetation
coverage, leaving them susceptible to slope
failure. Figure 2 shows the landslide zones in
the City of Rolling Hills, as mapped by the
California Geological Survey (CGS). Landslide
activity has been well documented in the
region. Relicts of landslides and rockslides are
present throughout the City of Rolling Hills.
2 “Beginning in” is defined as the first noted event of major
rock movement
The following major landslides have occurred
in and adjacent to the city. All are in the
landslide hazards areas identified in Figure 2:
▪ Portuguese Bend Landslide: Beginning in2
1956 over approximately 270 acres in
Rancho Palos Verdes
▪ Abalone Cove Landslide: Beginning in
1974 over 80 acres in Rancho Palos
Verdes
▪ Klondike Canyon Landslide: Beginning in
1979 over to the south near the coastline
▪ Flying Triangle Landslide: Beginning in
1970s or 1980s over approximately 70
acres in the southeast area of the city
The Flying Triangle Landslide, shown in Figure
2, continues to impact the southeast portion
of the city through impacts to private roads
and above-ground utility lines. This area is
relatively unsuitable for development due to
the ongoing changes in topography.
Seismic Hazards
Rolling Hills is in a seismically active region of
southern California. The last major
earthquake in the Los Angeles area was the
5.1 magnitude La Habra earthquake in 2014.
Rolling Hills is within 50 miles of the Whittier
fault, Newport-Inglewood fault, Palos Verdes
fault, Malibu Coast fault, Cabrillo fault, Santa
Monica fault, and Redondo Canyon fault.
Analysis of seismic data from the region
indicates that the Whittier and Newport-
Inglewood faults may generate a maximum
credible earthquake of magnitude 7.2 and
7.4, respectively (SCEC 2013). Figure 3 shows
the faults in the vicinity of Rolling Hills.
Typically, seismic shaking and fault rupture
are primary hazards as they occur as a direct
result of the interaction between the seismic
wave energy and the earth’s surface.
Secondary hazards, such as liquefaction and
earthquake-induced landslides, occur as a
result of the primary earthquake hazards.

Hazards of Concern
Safety Element 9
Often, earthquake activity can result in other
effects such as building damage/collapse,
infrastructure failure, pipeline breakage, and
damage to transportation and
communication facilities. The size of the
earthquake and distance from the fault
rupture zone typically determine the severity
of these events.
Seismic Shaking
Seismic shaking, or ground shaking, refers to
the movement of the earth’s surface resulting
from the energy release by an earthquake.
Seismic shaking is typically the primary cause
of property damage resulting from
earthquake activity. Seismic shaking can
destroy buildings, roadways, powerlines, and
pipelines. Energy transmitted through the
ground can travel hundreds of miles and may
cause damage in many locations
simultaneously. Closer proximity to the fault
rupture area results in stronger shaking in
that location.
The amount of ground shaking that occurs in
a location depends on the magnitude of the
earthquake, the distance from the epicenter,
and local soil conditions. The intensity of
ground shaking is related to the peak ground
velocity during an earthquake. As shown in
Figure 4, the earthquake shaking potential for
Rolling Hills is low to moderate. The intensity
of seismic shaking is measured using the
Modified Mercalli scale.
According to the CGS, an active fault is one
that has experienced surface movement in
the past 11,000 years. The city is located near
a number of active faults, including the
Cabrillo Fault in city limits. Table 3 includes a
list of nearby faults, their respective distance
from the city, the maximum credible
earthquake generated from each fault, and
the likelihood of earthquake occurrence in
each case.
The San Andreas fault is located
approximately 80 miles to the east of Rolling
Hills. Although the San Andreas fault is
located at a greater distance from the city,
seismic shaking originating from earthquakes
occurring along the San Andreas fault poses a
threat to the city. Figure 3 identifies the
active and inactive faults located in the city
and vicinity.
Fault Rupture
Fault Rupture occurs when seismic movement
on a fault break through the earth’s surface.
Hazards related to fault rupture arise when
structures are built near or on top of an active
fault. While there are a number of seismically
active faults in the city and region, there are
no active faults with the potential for ground
rupture, defined by the Alquist-Priolo
Earthquake Fault Zoning Act and delineated
by CGS. Figure 3 shows the designated
Alquist-Priolo study zones, the closest of
which is the Newport-Inglewood Fault
approximately nine miles northeast of the
city.

Liquefaction and Settlement
Liquefaction is a ground failure phenomenon
that occurs as a result of a seismic event.
Liquefaction increases water content in
surface soils until the soil reaches a semi-
liquid state, contributing to a reduction in
support, and ultimately resulting in shifting or
subsidence of buildings and utilities. Ground
failure typically occurs when the following
conditions exist:
▪ Loose, unconsolidated granular soils
▪ Shallow groundwater
▪ Strong seismic ground shaking
While Rolling Hills has moderate to high
seismic shaking potential, the subsurface soils
generally lack saturated alluvial deposits and
thick, granular soils. Figure 5 shows the
liquefaction hazard areas, which are in the
low-lying areas to the east and north,
generally surrounding the Los Angeles Harbor
and Harbor Lake. Liquefaction potential for
Rolling Hills is low, as shown in Figure 5.
Earthquake Induced Landslides
Ground failure or destabilization of slopes
resulting from an earthquake can also occur
following seismic activity in the form of
Earthquake-Induced Landslides. Earthquake-
induced landslides typically occur in areas
with steep slopes or unstable soil conditions.
As discussed above under Landslide Hazards,
the risk of landslide activity in Rolling Hills is
high. Much of the city overlies areas that have
been identified as landslide zones by the CGS.
Risk of landslide activity increases following
rainfall events that result in saturated soils.
Both shallow and deep seeded landslides
have historically occurred in the city.
Flooding
Rolling Hills participates in the Federal
Emergency Management Agency’s (FEMA)
National Flood Insurance Program. According
to the FEMA flood maps, the city is not
located in a flood hazard area and currently
has a less than 0.2 percent annual chance to
be inundated by flood waters as a result of a
storm event (FEMA 2008). Overall, the city is
not in any immediate risk from flooding
caused by overflowing water bodies or heavy
rains. However, runoff and minor flooding
pose a risk if drainage systems fail along
canyon bottoms, where natural drainage
leads.
Dam Inundation
No water storage facilities that the State of
California identifies as dams are located in
Rolling Hills. Just outside city limits are three
water storage facilities identified as dams,
which include:
▪ Palos Verdes Reservoir. Owned by the
Metropolitan Water District of Southern
California and located at the southeast
corner of Palos Verdes Drive East and
Palos Verdes Drive North. According to
the California Department of Water
Resources, the reservoir can hold
approximately 1,100 gallons of water and
has an extremely high downstream
hazard.
▪ 10 MG Walteria and 18 MG Walteria.
Two reinforced concrete tanks which are
owned by the City of Torrance and
located at Crenshaw Boulevard and Crest
Road. The tanks can hold 31 and 58 acre-
feet (AF) of water, respectively.
Senate Bill 92, adopted in 2017, is a new dam
safety requirement that requires dam owners
to map the downstream inundation areas for
dams governed by the Department of Water
Resources. Figure 6 shows the inundation
areas for the nearby water storage facilities.
Due to their locations and the topography of
the area, the inundation areas do not enter or
affect any portion of the city.

Wildland and Urban Fires
The entire City of Rolling Hills is designated a
Very High Fire Hazard Severity Zone (VHFHSZ)
by the California Department of Forestry and
Fire Protection (CalFire), as shown in Figure 7.
Rolling Hills terrain is comprised of several
large and steep canyons that limit and
challenge vegetation management and
present conditions where a fire can quickly
travels up and downslope to nearby homes.
Due to the rural nature and large residential
lots, many homes are surrounded by more
substantial vegetation and dense brush than
in more suburban settings. The bridle trails
for hikers and equestrian access also contain
dense vegetation and management
difficulties, which contributes to the fire risk
of the city. Electrical power lines pose a
hazard to starting fires in the city if lines are
not automatically de-energized when
knocked down by extreme weather or if the
surrounding vegetation is not adequately
managed.
There is a history of fires in the city and the
surrounding Palos Verdes Peninsula. Three
major fires have been documented on the
Peninsula and in the city in:
▪ 1923: an estimated 4,000 acres burned in
Palos Verdes Hills
▪ 1945: 3,000 acres burned
▪ 1973: approximately 900-925 acres
burned, 12 homes destroyed, and 10
homes damaged
▪ 2005: 212 acres burned near Del Cero
Park
▪ 2009: 230 acres burned, 6 homes
damaged, and forced 1,200 residents on
the Peninsula to evacuate
▪ 2015: 3 acres burned

For many of the developed residences in the
city that are vulnerable to fires, their risk may
increase with construction techniques that
may not meet current wildfire standards.
Rolling Hills Building Code and Los Angeles
County Fire Department, under the VHFHSZ
standards, require new development to
include more stringent design and material
standards for roofing, eaves, and rafter tails
as well as exterior finishes and fire buffer
zones. While compliance with these
standards reduces the vulnerability to new
structures, existing structures that have not
complied with these standards may be
susceptible to undue fire risk.

Hazardous Materials
According to the Department of Toxic
Substances Control (DTSC), there are no
hazardous waste sites or facilities in Rolling
Hills (DTSC 2020). The city and surrounding
area do not contain heavy industrial uses that
would create a hazardous material risk in the
event of a spill, release, or natural disaster.
The city is not located near any major transit
routes involving transport of a substantial
quantity of hazardous material through the
city. However, the nearby oil refineries
(located along Sepulveda Boulevard
approximately six miles northeast) and Port
operations (located approximately three
miles to the east) could create air quality
impacts if wind patterns and release events
occur. Air quality impacts are discussed in the
Open Space and Conservation Element of the
Rolling Hills General Plan.
Community
Communication
Emergency Response and
Evacuation
Police Response and Crime
The Los Angeles County Sheriff’s Department
is contracted with the city to provide police
services and protection to the city. The
Lomita Station of the Sheriff’s Department
located at 26123 Narbonne Avenue serves
the city.
According to the Lomita Station crimes report
from January 1, 2020, through December 31,
2020, Rolling Hills had 7 reported crimes
(LACSD 2020). The crimes were related to
theft, burglary, and arson. Outside the city
limits and in the Lomita District, 401 crimes
were reported during this same period, 79 of
which were violent crimes (LACSD 2021). The
difference in crimes in the city and the
surrounding area is attributed to the private
nature of the city. There are three entrances
to the city, all of which are gated and staffed
24 hours a day. Visitors are required to be on
a resident’s guest list to enter city limits,
reducing crime in the city and demand on Los
Angeles County Sheriff’s Department.
Fire Response
The Los Angeles County Fire Department
provides emergency operations support to
the City and participates in the California
mutual aid system. Mutual aid is emergency
assistance that is dispatched upon request
across jurisdictional boundaries. Fire Station
56, located at 12 Crest Road West, serves the
city under Battalion 14, which also serves the
remaining Palos Verdes Peninsula, Lomita,
and Avalon Canyon. Fire response constraints
in the city include ability to access certain
homes or areas due to inadequate road
widths for fire maneuvering. One of the major
topics of concern related to fire response in
the city relates to vegetation clearing along
roadways. Ten-foot clearance on each side of
the roadway, especially the limited access
roads, is important for fire response and
evacuation during a fire, according to Scott
Hale, Assistant Fire Chief.
Evacuation Strategies and Routes
Because a variety of hazards could affect city
residents, it is vital to identify critical routes
for evacuation in the event of a major event.
Senate Bill 99, adopted August 30, 2020,
requires cities to “identify residential
developments in any hazard area identified in
the safety element that does not have at least
two emergency evacuation routes.” Due to
the size of Rolling Hills and that it has four
evacuation routes, no neighborhoods have
been identified as not having two evacuation
routes. As shown on the Figure 8, the
evacuation routes also connect to major
300

roadways in the area that are multi-
directional such as Crenshaw Boulevard, Palos
Verdes Drive North and Palos Verdes Drive
East.
Figure 8 identifies the existing evacuation
routes in the city, which are:
▪ Main Gate at Rolling Hills Road and Palos
Verdes Drive North
▪ Crest Gate at Crest Road near Crenshaw
Blvd
▪ Eastfield Gate at Eastfield Drive and Palos
Verdes Drive East
▪ Crest Road East Gate at the end of Crest
Road East
Crest Road East Gate has been updated with a
motor and has no guards. This gate is
available as an emergency exit to the city
during emergencies. The City’s recently
adopted CWPP establishes evacuation
strategies and methodologies, including:
▪ Using the City’s Block Captains3 as
important coordinators for residents
▪ Communication goals between the City,
emergency responders, Rolling Hills
Community Association, and residents
▪ Details for residents regarding how
people get notified during an evacuation
▪ Responsibilities and operations of the
Emergency Operations Center
Disease Prevention
As evidenced by the COVID-19 pandemic,
unforeseen infectious diseases can be
disastrous for communities, especially
vulnerable groups such as older adults, and
people with compromised immune systems.
The City worked diligently during the
pandemic to minimize risk to community
members. The Block Captains regularly
checked in on old adults in the community,
Fire Station Trail
3 The Rolling Hills Block Captain Program is a city-sponsored,
resident-based community program of volunteers. Their role is
to get to know neighbors, help them to prepare for an
emergency, and be a liaison between first responders and City
of Rolling Hills during an emergency.

finding out what residents needed, helping
run errands, and providing hand sanitizer
Additionally, the City disseminated
information regularly including where to buy
groceries at the beginning of the pandemic,
testing information, and more. Policies
regarding infectious disease can help expedite
recovery and prepare the community for
future risks.
Climate Change
Climate change is expected to affect future
occurrences of natural hazards in and around
Rolling Hills. Some hazards are projected to
become more frequent and intense in the
coming decades, and in some cases, climate
impacts have already begun.
In developing the Safety Element, the City
competed a Climate Change Vulnerability
Assessment consistent with Government
Code Section 65302(g), which assesses how
the populations and assets in Rolling Hills are
vulnerable to different climate hazards. The
full Climate Change Vulnerability Assessment
can be found in Appendix A: Existing
Conditions Report. According to the
Vulnerability Assessment, the city is most
vulnerable to wildfire impacts, extreme heat,
and landslide impacts from climate change.
According to the Vulnerability Assessment
and the California’s Fourth Climate Change
Assessment, Rolling Hills can expect the
following changes to natural hazard events:
▪ Projected annual average maximum
temperature is expected to increase in
Rolling Hills between 1.8- and 6.6-degrees
Fahrenheit (°F) compared to 1990,
depending on the greenhouse gas (GHG)
emissions scenario.4
4 The Vulnerability Assessment uses two GHG emissions
scenarios: Representative Concentration Pathway (RCP) 4.5
and RCP 8.5. RCP 4.5 describes a scenario in which GHG
▪ Extreme heat events are also expected to
increase in Rolling Hills. The annual
number of average extreme heat days is
projected to increase from a baseline of 4
between 1950 and 2005 to 8 or 14
between 2030 and 2099, depending on
the GHG emissions scenario.
▪ Although only small changes in average
precipitation are projected, the Los
Angeles Region, which includes Rolling
Hills, is expected to experience dry and
wet precipitation extremes and higher
frequency and severity of storms.
Increasing storm intensity may
exacerbate landslide hazards in the city.
Warmer and drier conditions state-wide
could increase the prevalence of drought
conditions that could impact Rolling Hills.
▪ Wildfire is projected to increase over all
of southern California.
Vulnerable Populations
and Assets
As climate change occurs, communities will
be affected to varying degrees and impacts
depending on the hazard as well as how
sensitive the communities are to impacts.
Virtually all people and assets in a community
will be affected by climate change in some
way, but some communities may be more
sensitive. The Vulnerability Assessment
identified the following sensitivities:
Populations
▪ Children. Approximately 6.6 percent of
the total population in Rolling Hills are
ten years old or younger.
▪ Persons in Poverty. This is identified for
people living in households with an
income below the poverty limit, which is
$26,200 for a household of four people.
There are approximately 26 people in
emissions peak around 2050 and then decline. RCP 8.5 is the
scenario in which GHG emissions continue to rise through 2050
before leveling off around 2100.

Safety Element 21
Rolling Hills who live in poverty, or
approximately 1.6 percent of the total
population for whom poverty status can
be determined.
▪ Persons with Chronic Health Conditions.
These are people who have a long-term
or permanent health condition that can
create regular challenges in their day-to-
day lives. These health problems include
obesity, cancer, heart disease, and
arthritis. In addition, those with any kind
of disability, including mobility challenges,
hearing, or vision impairments,
behavioral disabilities, and challenges
living independently or taking care of
themselves. Approximately 11.5 percent
of the population have identified having a
disability.
▪ Renters. These are people who live in
homes that they (or the head of their
household) do not own. Approximately 24
housing units, or 4 percent of the housing
units in Rolling Hills, are renter-occupied.
▪ Older Adults. These are persons 65 years
or older are more at risk for climate
change impacts, especially those living
alone. 28 percent of the population of
Rolling Hills are over 65 years, and 15
percent of those over 65 years live alone.
▪ Limited English Proficiency.
Approximately three percent of
households have identified being limited
English-speaking. Of those, a majority
spoke Asian and Pacific Island languages
and Spanish.
Infrastructure
▪ Access Roads. These roadways are one of
a few, or the only, ways in and out of
some communities or neighborhoods.
The single or limited number of entry and
exit points does not make the road itself
more vulnerable than other roads, but
loss of these roadways can effectively cut
off large numbers of people from other
areas in the Palos Verdes Peninsula and
the rest of Los Angeles County.
Portuguese Bend Road and Crest Road
are the primary access roads into and out
of the city.
▪ Bridle Trails. Throughout the community
are over 25 miles of trails available to
residents and non-city residents who
obtain permits. The trails are maintained
by the Rolling Hills Community
Association and located primarily in
canyon areas.
▪ Electrical Substations. Electrical
substations are facilities that convert
electricity from one voltage to another,
making it suitable for long-distance
transmission or for use by homes,
businesses, and other electrical
customers. There are no electrical
substations located in city limits, but
three are located near the city in Rancho
Palos Verdes and owned/operated by
Southern California Edison.
▪ Electrical Utility Lines. These lines
transmit and deliver electricity from
Southern California Edison to the city. The
city has both underground and overhead
electric utility lines.
▪ Natural Gas Transmission Pipelines.
Natural gas pipelines carry large volumes
of natural gas between communities.
There are no transmission lines in the
city. One transmission line ends at the
intersection of Rolling Hills Road and
Palos Verdes Drive North, adjacent to city
limits.
▪ Water Reservoirs and System. The
system that stores and supplies drinking
water for residents. Palos Verdes Water
District of the California Water Service
supplies water to Rolling Hills. There are
two California Water Service water
reservoirs in the city limits.
Services
▪ Public Safety Response. Public safety
services are provided by law enforcement
304
City of Rolling Hills
Rolling Hills General Plan
22
and fire agencies. These agencies include
the Los Angeles County Sheriff and Fire
Departments.
▪ Water Services. These services involve
treating and transporting water to be
used by customers and transporting and
treating wastewater so it can be safely
released into the environment. California
Water Service provides drinking water to
the city.
▪ Energy Delivery. Energy services in
Rolling Hills include electricity and natural
gas delivered through utility lines from
Southern California Edison and Southern
California Gas Company.
Vulnerability Assessment
Results
The Vulnerability Assessment indicates that
the city’s populations, infrastructure, and
services are most vulnerable to wildfire,
extreme heat, and extreme precipitation
events.
Populations
Vulnerable populations such as older adults,
residents with chronic health conditions, and
those with financial trouble are most at risk to
extreme heat and wildfire impacts.
28 percent of the city’s population is over 65
years. Older adults do not adjust as well as
young people to sudden changes in
temperature and are more likely to have
medical conditions that can worsen with
extreme heat (CDC 2017a). Older adults who
are living alone are even more at risk as the
actions necessary to mitigation extreme heat
are more difficult alone. Getting water,
changing clothes, showering, or turning on
the air conditioner may be more difficult for
older adults with physical disabilities and do
not have a partner to assist them. Extreme
heat can be highly dangerous to persons with
chronic health conditions, because very high
temperatures can exacerbate diabetes,
cardiovascular conditions, respiratory
ailments, and other diseases. Some of these
people have weakened immune systems
which can make them more likely to contract
illnesses and vulnerable to human health
hazards. In addition, they may be taking
medications that make the effects of extreme
heat worse (CDC 2017b). While there are not
many households in poverty in the city, those
who are have limited financial resources to
upgrade their homes to have air conditioning
to better resist extreme heat.
Older adults, residents with chronic health
conditions, and those with financial trouble
are the populations most at risk to wildfire
impacts. Older adults are almost three times
more likely to die in a fire than the overall
population (USFA 2017), and typically have
increased mobility or mental health issues.
Therefore, older adults, especially those in
the city living alone, have more difficulties
evacuating to safe areas when there is a
need. Those in Rolling Hills with limited
financial resources are more unlikely to
retrofit their homes to better resist climate-
related hazards such as wildfires. In addition
to direct impacts, indirect impacts such as
poor air quality also creates public health
hazards to the city. Recent California wildfires
in August and September 2020 had areas of
California recording the worst air quality in
the world and highlighted the hazards of
secondary impacts from wildfires, which
could impact the city from fires throughout
the State. Older adults and individuals with
chronic health conditions are likely to be
impacted most by these secondary impacts.
Also, those with limited finances or without
air conditioning would be impacted by
secondary smoke impacts that occur during
local and regional wildfires.
Infrastructure
Access roads, residential structures, and
community facilities and government
buildings are the most vulnerable
305
Climate Change
Safety Element 23
infrastructure to wildfire and extreme
precipitation impacts from climate change.
All city infrastructure is located in a VHFHSZ.
Portuguese Bend Road and Crest Road are
critical for access to and evacuation from
many areas of the city. Wildfires may not
significantly damage the infrastructure, but
they could result in closure or the inability to
travel on them during wildfire events, which
can isolate areas of the city and create severe
health and safety risks. Wildfires are unlikely
to substantially damage trails directly, but
they can force widespread trail closures
which are an important asset to the
community.
The greatest potential impact of life and well-
being would be to residential structures,
which are the primary structures in the city.
In addition, impacts to Rolling Hills
Community Association and City Hall
structures would impact community functions
and government services.
Critical infrastructure most at risk in Rolling
Hills to minor flooding impacts and landslides
from increased storms would be access roads,
bridle trails, electrical utility lines, and water
systems. Because Portuguese Bend Road and
Crest Road are critical for access to and
evacuation from the city, any damage or
closure can effectively isolate areas of the
city, potentially creating severe health and
safety risks. Bridle trails are predominantly
located in canyon areas, which would be
more susceptible to flooding and landslides.
Landslides could impact utilities, as seen in
the existing Flying Triangle Landslide area,
which has moved utility lines above ground in
certain areas due to the continuous
movement of the earth in this area. Due to
the limited accessibility of the city, there is a
medium potential for impacts to access roads
and bridle trails and a low potential impact
for the remaining vulnerable infrastructure.
Services
Energy delivery, specifically electricity
delivery, could be impacted from increased
wildfires. Direct impacts to Southern
California Edison electricity transmission
infrastructure could impact power in the city.
In addition, utility companies have begun
shutting off power to areas to avoid wildfires
during times when weather creates high
wildfire risk. Public safety services could be
strained during wildfire events, which are
expected to increase.
Overall, climate change impacts from wildfire
are projected to have the greatest potential
impact to the city.

Summary
Key Findings
The city is most at risks to impacts from wildfire, extreme heat, and landslide events, which are
all anticipated to increase as a result of climate change impacts. Vulnerable populations such as
older adults and residents with chronic health conditions are most at risk to extreme heat and
wildfire impacts. Access roads and residential structures are also the most vulnerable to wildfire
and landslide impacts from climate change.
The city has a moderate risk for shaking potential from earthquakes.
Flood risks in the city are minimal and limited to natural drainage areas in the canyons.
Vegetation clearing along roadways is a concern and major goal for improving fire response and
evacuation in the city.
Evacuation strategies and education are important to reduce risk from hazards due to the lack
of evacuation routes in the city and the remote development on private roads. The need to
further analyze evacuation routes and access is one of the most recent changes in Safety
Element requirements. A key opportunity for the Safety Element update is to address specific
evacuation needs.
The City has recently adopted a number of planning documents such as the Hazard Mitigation
Plan and Community Wildfire Protection Plan, which seek to reduce the risk of hazards in the
city. An opportunity for the Safety Element update would be to utilize existing
recommendations from the Community Wildfire Protection Plan as implementation tools for the
Safety Element.

Introduction
Section 65302(g) of the California Government Code requires that the General Plan include a Safety
Element for the protection of the community from any unreasonable risks associated with the
effects of seismically induced surface rupture, ground shaking, ground failure, tsunami, seiche, and
dam failure; slope instability leading to mudslides and landslides; subsidence and other geologic
hazards; flooding, wildland and urban fire, and climate change adaptation and resilience. In
addition, Safety Elements are required to address non-hazard specific issues such as peak load water
supply, evacuation routes, and military installations.
This Existing Conditions Report is a comprehensive assessment of natural and man-made hazards
for the City of Rolling Hills. The report serves as the foundation for the Safety Element and includes
detailed Geographic Information System (GIS) hazard mapping and analyses. The following City
plans were also utilized for this report along with existing local data from governmental agencies
and scientific research: Hazard Mitigation Plan, Community Wildfire Protection Plan, and the
existing Safety Element.
Setting
Rolling Hills covers an area of approximately three square-miles on the Palos Verdes peninsula,
approximately 18 miles south of downtown Los Angeles. The topography of the city and peninsula
area is unique in that it rises above the Los Angeles Basin with rolling hills, steep slopes, and
canyons. The city itself is located in the San Pedro Hills. Due to its location near the coast, the area is
cooler and has fewer air quality concerns compared to the nearby Los Angeles Basin. Table 1
summarizes the climatology of the area.

Rolling Hills is a residential community that consists of large parcels and ranch-style homes and has
a sizable older adult 1 population of about 513 (28% of the city’s total population). The city is also an
equestrian community, as many of residents are horse owners or have horses on their property.
Important community demographic data for Rolling Hills is included in Table 2.

Critical Facilities and Infrastructure
Critical facilities are places that provide emergency services or serve people who would be impacted
by an emergency. Examples include hospitals, fire stations, police stations, emergency services
facilities, utility facilities, and communication facilities. Critical facilities can also include the
transportation system and schools. Due to the size and composition of Rolling Hills, most of the
critical facilities that serve the city are located outside of City limits. Critical facilities that serve the

Hazards of Concern
Geologic Hazards
Geologic processes that pose a threat to life, health, property, or infrastructure are considered
geologic hazards. Natural geologic hazards that have the potential to affect Rolling Hills include
seismic hazards, landslides, liquefaction, expansive soils, and weathering. In most cases, these
natural processes cannot be prevented; however, the magnitude of destruction resulting from
natural geologic hazards can be reduced through planning policies and measures.
Landslide Hazards
Landslide activity refers to a wide range of gravity driven downslope earth movement, including
rockslides, rotational slips, mudslides, and shallow debris flows. Geological and geomorphological
conditions such as soil type, soil strength, slope angle, and slope height predispose slopes to failure.
Other factors affecting the susceptibility to slope failure include the amount of precipitation,
vegetation on the slope, groundwater seepage, and human modifications to the slope. Landslides
often result in damage to property and roadways and can cause them to become unsafe due to
displacement of the subsurface.
A majority of the existing development in Rolling Hills is located on hilly terrain and have a greater
potential to experience landslide hazards. Many of the canyons in Rolling Hills exhibit steep slopes
with little vegetation coverage, leaving them susceptible to slope failure. Figure 2 shows the
landslide zones within the City of Rolling Hills, as mapped by the California Geological Survey.
Landslide activity has been well documented in the region. Relicts of landslides and rockslides are
present throughout the City of Rolling Hills. The following major landslides have occurred within and
adjacent to the city. All are within the landslide hazards areas identified in Figure 2:
Portuguese Bend Landslide: Beginning in 2 1956 over approximately 270 acres in Rancho Palos
Verdes
Abalone Cove Landslide: Beginning in 1974 over 80 acres in Rancho Palos Verdes
Klondike Canyon Landslide: Beginning in 1979 over to the south near the coastline
Flying Triangle Landslide: Beginning in 1970s or 1980s over approximately 70 acres in the south
area of the city
The Flying Triangle Landslide continues to impact the southeast portion of the city through impacts
to private roads and requiring above-ground utility lines. This area is relatively unsuitable for
development due to the ongoing changes in topography.
Seismic Hazards
Rolling Hills is located in a seismically active region of southern California. The last major earthquake
in the Los Angeles area was the 5.1 magnitude La Habra earthquake in 2014. Rolling Hills is located
within 50 miles of the Whittier fault, Newport-Inglewood fault, Palos Verdes fault, Malibu Coast
2 “Beginning in” is defined as the first noted event of major rock movement

fault, Cabrillo fault, Santa Monica fault, and Redondo Canyon fault. Analysis of seismic data from the
region indicates that the Whittier and Newport-Inglewood faults may generate a maximum credible
earthquake of magnitude 7.2 and 7.4, respectively (Southern California Earthquake Center 2013).
Figure 3 shows the faults in the vicinity of Rolling Hills.
Typically, seismic shaking and fault rupture are primary hazards as they occur as a direct result of
the interaction between the seismic wave energy and the earth’s surface. Secondary hazards, such
as liquefaction and earthquake-induced landslides, occur as a result of the primary earthquake
hazards. Often, earthquake activity can result in other effects such as building damage/collapse,
infrastructure failure, pipeline breakage, and damage to transportation and communication
facilities. The size of the earthquake and distance from the fault rupture zone typically determine
the severity of these events.
Seismic Shaking
Seismic shaking, or ground shaking, refers to the movement of the earth’s surface resulting from the
energy release by an earthquake. Seismic shaking is typically the primary cause of property damage
resulting from earthquake activity. Seismic shaking has the ability to destroy buildings, roadways,
powerlines, and pipelines. Energy transmitted through the ground has the potential to travel
hundreds of miles and may cause damage in many locations simultaneously. Closer proximity to the
fault rupture area results in stronger shaking in that location.
The amount of ground shaking that occurs in a location is dependent on the magnitude of the
earthquake, the distance from the epicenter, and local soil conditions. The intensity of ground
shaking is related to the peak ground velocity during an earthquake. According to the CGS Map
Sheet 48, the earthquake shaking potential for Rolling Hills is moderate. The intensity of seismic
shaking is measured using the Modified Mercalli scale.
According to the California Geologic Survey, an active fault is one that has experienced surface
movement in the past 11,000 years. The city is located near a number of active faults, including the
Cabrillo Fault within city limits. Table 3 includes a list of nearby faults, their respective distance from
the city, the maximum credible earthquake generated from each fault, and the likelihood of
earthquake occurrence in each case.
Table 3 Faults Located within 50 Miles of Rolling Hills
Fault Name Approximate Distance from Rolling Hills
Whittier 25 miles east
Newport-Inglewood 9 miles east
Palos Verdes <1 mile north
Malibu Coast 20 miles northwest
Cabrillo Located within the City boundaries in the southwest
Santa Monica 20 miles north-northwest
The San Andreas fault is located approximately 80 miles to the east of Rolling Hills. Although the San
Andreas fault is located at a greater distance from the city, seismic shaking originating from
earthquakes occurring along the San Andreas fault poses a threat to the city. Figure 3 identifies the
active and inactive faults located within the city and vicinity.
337
Hazards of Concern
Existing Conditions Report 9
Fault Rupture
Fault Rupture occurs when seismic movement on a fault breaks through the earth’s surface. Hazards
related to fault rupture arise when structures are built near or on top of an active fault. While there
are a number of seismically active faults in the city and region, there are no active faults with the
potential for ground rupture, defined by the Alquist-Priolo Earthquake Fault Zoning Act and
delineated by CGS. Figure 3 shows the designated Alquist-Priolo study zones, the closest of which is
the Newport-Inglewood Fault approximately nine miles northeast of the city.
Liquefaction and Settlement
Liquefaction is a ground failure phenomenon that occurs as a result of a seismic event. Liquefaction
increases water content in surface soils until the soil reaches a semi-liquid state, contributing to a
reduction in support, and ultimately resulting in shifting or subsidence of buildings and utilities.
Ground failure typically occurs when the following conditions exist:
Loose, unconsolidated granular soils
Shallow groundwater
Strong seismic ground shaking
While the Rolling Hills has moderate to high seismic shaking potential, the subsurface soils generally
lack saturated alluvial deposits and thick, granular soils. Figure 4 shows the liquefaction hazard
areas, which are located in the low-lying areas to the east and north, generally surrounding the Los
Angeles Harbor and Harbor Lake. Liquefaction potential for Rolling Hills is low, as shown in Figure 4.
Earthquake Induced Landslides
Ground failure or destabilization of slopes resulting from an earthquake can also occur following
seismic activity in the form of Earthquake-Induced Landslides. Earthquake-induced landslides
typically occur in areas with steep slopes or unstable soil conditions. As discussed above under
Landslide Hazards, the risk of landslide activity in Rolling Hills is high. Much of the city overlies areas
that have been identified as landslide zones by the California Geological Survey. Risk of landslide
activity increases following rainfall events that result in saturated soils. Both shallow and deep
seeded landslides have historically occurred in the city.
Flooding
Rolling Hills participates in the Federal Emergency Management Agency’s (FEMA) National Flood
Insurance Program. According to the FEMA flood maps, the city is not located in a flood hazard area
and currently has a less than 0.2 percent annual chance to be inundated by flood waters as a result
of a storm event (FEMA 2008). Overall, the city is not in any immediate risk from flooding caused by
overflowing water bodies or heavy rains. However, runoff and minor flooding pose a risk if drainage
systems fail along canyon bottoms, where natural drainage leads to.

Dam Inundation
No water storage facilities that the State of California identifies as dams are located in Rolling Hills.
Just outside city limits are three water storage facilities identified as dams, which include:
Palos Verdes Reservoir: Owned by the Metropolitan Water District of Southern California and
located at the southeast corner of Palos Verdes Drive East and Palos Verdes Drive North.
According to the California Department of Water Resources, the reservoir can hold
approximately 1,100 gallons of water and has an extremely high downstream hazard.
10 MG Walteria and 18 MG Walteria: Two reinforced concrete tanks which are owned by the
City of Torrance and located at Crenshaw Boulevard and Crest Road. The tanks can hold 31 and
58 acre-feet (AF) of water respectively.
Senate Bill 92, adopted in 2017, is a new dam safety requirement that requires dam owners to map
the downstream inundation areas for dams governed by the Department of Water Resources.
Figure 5 shows the inundation areas for the nearby water storage facilities. Due to their locations
and the topography of the area, the inundation areas do not enter or affect any portion of the city.
Wildland and Urban Fires
The entire City of Rolling Hills is designated a Very High Fire Hazard Severity Zone (VHFHSZ) by the
California Department of Forestry and Fire Protection (CalFire), as shown in Figure 6. Rolling Hills
terrain is comprised of several large and steep canyons that limit and challenge vegetation
management and present conditions where a fire can quickly travels up and downslope to nearby
homes. Due to the rural nature and large residential lots, many homes are surrounded by
substantial vegetation and dense brush than in more suburban settings. The bridle trails for hikers
and equestrian access also contain dense vegetation and management difficulties, which
contributes to the fire risk of the city. Electrical power lines pose a hazard to starting fires in the city
if lines are not automatically de-energized when knocked down by extreme weather or if the
surrounding vegetation is not adequately managed.
There is a history of fires in the city and the surrounding Palos Verdes Peninsula. Three major fires
have been documented on the Peninsula and in the city in:
1973: almost 1,000 acres burned, and 13 homes destroyed
2005: 212 acres burned near Del Cero Park
2009: 230 acres burned and forced 1,200 residents on the Peninsula to evacuate
For many of the developed residences in the city that are vulnerable to fires, their risk may increase
with the presence of construction techniques that may not meet current wildfire standards. Rolling
Hills Building Code and Los Angeles County Fire Department, under the VHFHSZ standards, require
new development to include more stringent design and material standards for roofing, eaves, and
rafter tails as well as exterior finishes and fire buffer zones. While compliance with these standards
reduces the vulnerability to new structures, existing structures that have not complied with these
standards may be susceptible to undue fire risk.

Hazardous Materials
According to the Department of Toxic Substances Control (DTSC), there are no hazardous waste
sites or facilities in Rolling Hills (DTSC 2020). The city and surrounding area do not contain heavy
industrial uses that would create a hazardous material risk in the event of a spill, release, or natural
disaster.
The city is not located near any major transit routes involving transport of a substantial quantity of
hazardous material through the city. However, the nearby oil refineries (located along Sepulveda
Boulevard approximately six miles northeast) and Port operations (located approximately three
miles to the east) could create air quality impacts if wind patterns and release events occur. Air
quality impacts are discussed in the Open Space and Conservation Element of the Rolling Hills
General Plan.
Emergency Response and Evacuation
Police Response and Crime
The Los Angeles County Sheriff’s Department is contracted with the city to provide police services
and protection to the city. The Lomita Station of the Sheriff’s Department located at 26123
Narbonne Avenue, approximately 1.5 miles northeast of the Portuguese Bend Road entrance, serves
the city.
According to the Lomita Station crimes report from January 1, 2020, through June 30, 2020, Rolling
Hills had three reported crimes (LACSD 2020). The crimes were related to theft, assault, and
burglary. Outside the city limits and in the Lomita District, 433 crimes were reported during this
same period, 71 of which were violent crimes (LACSD 2020). The difference in crimes in the city and
the surrounding area is attributed to the private nature of the City. There are three entrances to the
city, all of which are gated and staffed 24 hours a day. Visitors are required to be on a resident’s
guest list in order to enter city limits. This reduces crime within the city and demand on Los Angeles
County Sheriff’s Department.
Fire Response
The Los Angeles County Fire Department provides emergency operations support to the City. Fire
Station 56, located at 12 Crest Road West, serves the city under Battalion 14, which also serves the
remaining Palos Verdes Peninsula, Lomita, and Catalina Island. Fire response constraints in the city
include ability to access certain homes or areas due to inadequate road widths for fire maneuvering.
One of the major topics of concern related to fire response in the city relates to vegetation clearing
along roadways. Ten-foot clearance on each side of the roadway, especially the limited access
roads, is important for fire response and evacuation during a fire, according to Scott Hale, Assistant
Fire Chief.
Evacuation Strategies and Routes
Because a variety of hazards could affect city residents, it is vital to identify critical routes for
evacuation in the event of a major event. Figure 7 identifies the existing evacuation routes in the
city, which are limited to:
Main Gate at Rolling Hills Road and Palos Verdes Drive North

Crest Road East Gate at the end of Crest Road East gate has recently been updated with a motor and
has no guards. This gate is available as an emergency exit to the city during emergencies. The
recently adopted Community Wildfire Protection Plan for the city establishes evacuation strategies
and methodologies for the city, which include:
Using the City’s Block Captains as important coordinators and managers of residents in the 24
City zones 3
Communication goals between the City, emergency responders, Rolling Hills Community
Association, and residents
Details for residents regarding how people get notified during an actual evacuation and the
responsibilities and operations of the Emergency Operations Center
Traffic control responsibilities and levels
Identification of special need residents who may need specific attention and/or assistance
3 The city is divided into 24 zones and each zone has 2-3 block captains to represent the residents within the zone.

Climate Change Vulnerability
Existing Conditions Report 19
Climate Change Vulnerability
In accordance with Senate Bill 379, this section provides a climate change vulnerability assessment
for Rolling Hills, which evaluates the potential impacts of climate change on community assets and
populations. The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report
defines vulnerability as “the propensity or predisposition to be adversely affected.” It adds that
vulnerability “encompasses a variety of concepts and elements including sensitivity or susceptibility
to harm and lack of capacity to cope and adapt” (IPCC, 2013). Understanding the vulnerabilities that
the city may face due to climate change provides a foundation to define future adaptation strategies
for the Safety Element update and other planning efforts in Rolling Hills and the region.
Consistent with the California Adaptation Planning Guide (Cal OES 2020) the assessment is
comprised of the following five elements:
Exposure – the nature and degree to which the community experiences a stress or hazard;
Sensitivity – the aspects of the community (i.e., people, structures, and functions) most affected
by the identified exposures;
Potential Impacts – the nature and degree to which the community is affected by a given
stressor, change, or disturbance;
Adaptive Capacity – the ability to cope with extreme events, to make changes, or to transform
to a greater extent, including the ability to moderate potential damages and to take advantage
of opportunities; and
Vulnerability Scoring – systematic scoring based on potential impacts and adaptive capacity, to
inform major climate vulnerabilities to address adaptation framework strategies.
In addition to City data, Cal-Adapt was used to complete the assessment. Cal-Adapt is an interactive,
online platform developed by the University of California and Berkeley to synthesize climate change
projections and climate impact research for California’s scientists and planners. This assessment
uses Cal-Adapt to study potential future changes in average and extreme temperatures,
precipitation, wildfire, and storms. Cal-Adapt is consistent with State guidance to use the “best
available science” for evaluating climate change vulnerability.
This assessment uses two greenhouse gas (GHG) emissions scenarios included in Cal-Adapts
analysis: Representative Concentration Pathway (RCP) 4.5 and RCP 8.5. RCP 4.5 describes a scenario
in which GHG emissions peak around 2050, decline over the next 30 years and then stabilize by
2100 while RCP 8.5 is the scenario in which GHG emissions continue to rise through the middle of
the century before leveling off around 2100. The climate projections used in this report are from
four models selected by California’s Climate Action Team Research Working Group and the
California Department of Water Resources. These models include:
A warm/dry simulation (HadGEM2-ES)
A cooler/wetter simulation (CNRM-CM5)
An average simulation (CanESM2)
348

The model that presents a simulation most unlike these three and incorporates 10 other
models, for full representation of possible forecasts (MIROC5)4
The average of the model projections is used in this analysis.
Exposure
Climate change is a global phenomenon that has the potential to adversely affect local health,
natural resources, infrastructure, emergency response, and many other facets of society. Projected
changes to climate are dependent on location. According to Cal-Adapt, climate change could lead to
increasing temperatures, temperature extremes, and changes in precipitation patterns in Rolling
Hills. These conditions could lead to exposure associated with extreme heat, drought, wildfires, and
extreme storms in the region. The climate hazards of concern for Rolling Hills addressed in this
analysis are:
Extreme Heat
Storms and Extreme Weather
Drought
Wildfire
Extreme Heat
Figure 8 below shows observed and projected annual average maximum temperature in Rolling
Hills. As shown in Figure 8, average temperatures in the city and region have increased, which is a
trend at both the local scale and the global scale. Compared to 1990, annual average maximum
temperatures in Rolling Hills are expected to rise between 1.8°F and 6.6°F by the end of the century,
depending on the GHG emissions scenario (CEC 2020).
4 There were 10 California GCM models that were ranked from 1-10 by California’s Climate Action Team Research Working Group and the
California Department of Water Resources for different temperature and precipitation factors. The models ranged from the “warm/dry”
model which had all metrics closest to 1 to the “cool/wet” model which had all metrics closest to 10. The MIROC5 displays a pattern of
ranking that is most unlike the other 3 models and therefore, is included to represent the full spread of all 10 model simulations.

Existing Conditions Report 21
Figure 8 Historical and Projected Annual Average Maximum Temperature in Rolling
Hills 5
Extreme heat is a period when temperatures are abnormally high relative to the normal
temperature range. There are generally three types of extreme heat events:
Extreme Heat Days: a day during which the maximum temperature surpasses 98 percent of all
historic high temperatures for the area, using the time between April and October from 1950 to
2005 as the baseline
Warm Nights: a day between April to October when the minimum temperature exceeds 98
percent of all historic minimum daytime temperatures observed between 1950 to 2005
Extreme Heat Waves: a successive series of extreme heat days and warm nights where extreme
temperatures do not abate. While no universally accepted minimum length of time for a
heatwave event exists, Cal-Adapt considers four, successive extreme heat days and warm nights
to be the minimum threshold for an extreme heatwave
Extreme heat events will feel different from region to region since different areas have different
historic high temperatures. For example, an extreme heat day on the coast will feel different than
an extreme heat day in the desert. According to Cal-Adapt, an extreme heat day in Rolling Hills
involves a temperature that exceeds 91.7 ̊F (CEC 2020).
Historically (between 1950 and 2005), Rolling Hills experienced an average four extreme heat days
per year, typically occurring between April and October. As a result of rising average temperatures
and climate change as discussed above, the city is projected to experience between 8 and 14
extreme heat days annually from 2030 to 2099 under medium and high emissions projections (CEC
5 Chart shows annual average maximum temperature for Rolling Hills (Grid Cell 33.78125, -118.34375) under RCP 8.5 (emissions continue

2020). As shown in Figure 9, the number of extreme heat days each year is variable, but overall they
are increasing from historic averages and would continue to increase through the century.
Figure 9 Number of Extreme Heat Days by Year in Rolling Hills 6
Extreme heat waves are defined as four or more consecutive extreme heat days. These events have
been historically infrequent in Rolling Hills, with the historical average being 0.3 heat waves
annually. The city is expected to experience a minor increase in heat wave frequency as the climate
changes. Between 2030 and 2099, the city is projected to experience between 0.4 and 1.1 heat
waves per year (CEC 2020).
Drought
Droughts are somewhat frequent in California, and currently approximately 42 percent of
California’s population are in a drought, or in an abnormally dry area (NIDIS 2020). Changes in
weather patterns resulting in increases in global average temperatures are already causing
decreases in snowpack, which provides as much as a third of California’s water supply (DWR 2019).
According to the U.S. Drought Monitor, Los Angeles County and Rolling Hills are not currently
experiencing drought conditions based on this mapping (National Drought Mitigation Center 2020).
Southern California is not currently considered to be in a drought condition, while other parts of the
State (northern California and the Sierra Nevada mountain range) are experiencing moderate
drought conditions due to lower than average precipitation.
The projected changes in annual precipitation for Rolling Hills are shown in Table 4. Under both the
medium and high GHG emissions scenarios, Rolling Hills is not expected to experience substantial
changes in average precipitation. However, the city would experience increased variability in
precipitation. The city’s minimum annual precipitation would decrease while the maximum annual
precipitation would increase under both emissions scenarios.

While overall precipitation levels are expected to change substantially in the city, a drought may
occur when conditions in areas where water sources are located experience drought conditions,
even though the local region does not. Rolling Hills obtains its water from the Palos Verdes District
of the California Water Service. Water supply from the District to this area is purchased from the
Metropolitan Water District of Southern California (MWD), which imports its water from the
Colorado River and State Water Project from northern California.
Recent research suggests that extended drought occurrence could become more pervasive in future
decades (CEC 2020). An extended drought scenario is predicted for all of California from 2051 to
2070 under a climate model using business as usual conditions. The extended drought scenario is
based on the average annual precipitation over 20 years. This average value equates to 78 percent
of the historic median annual precipitation averaged for the North Coast and Sierra California
Climate Tracker regions. Overall precipitation levels in the city are not expected to be significantly
impacted. However, variability in precipitation and drought conditions in other areas of the state
could impact water supply.
Wildfire
Wildfire hazards to the city are widespread and discussed above under Hazards of Concern.
Wildfires in the city are influenced by a range of factors including droughts, severe winds, wildfire
fuel (i.e. dry vegetation), and previous wildfire suppression activity. Climate change is expected to
exacerbate wildfire risk by creating hotter and drier landscapes, as discussed above under Extreme
Heat, which are more susceptible to burning.
Cal-Adapt provides projections for annual mean hectares burned. This projection only accounts for
areas that could experience wildfire events. Los Angeles County wildfire occurrence is anticipated to
increase under all emissions and population scenarios from historic averages (CEC 2020). In 2020
alone, California has experienced six of the 20 largest fires in modern history and as of the date of
this report, over three million acres of land have burned. These fires arose during extreme fire
weather conditions and record-breaking heat waves across California. The observed frequency of
autumn days with extreme fire weather, which are associated with extreme autumn wildfires, has
more than doubled in California since the early 1980s (Goss et al. 2020). Due to the increases in
factors that contribute to wildfires (variability in precipitation, hotter and dryer landscapes) and
because the city is in a VHFZSZ, it is expected to see an increase in wildfire hazards due to climate
change.
Storms and Extreme Weather
A warming climate is likely to influence the frequency and intensity of storms. Both increased
temperatures and altered precipitation patterns can lead to altered seasons and intense rainstorms
in Rolling Hills. As depicted in Figure 10, there is a high degree of variability in these extreme
352
City of Rolling Hills
Rolling Hills General Plan Safety Element
24
precipitation event projections, with some models projecting little to no change while others project
increased intensity (CEC 2020) These projections further vary depending on the return period7
selected. Increasing intensity of rainstorms could result in more flooding, which could adversely
affect human safety in Rolling Hills. During years of intense levels of precipitation and storms, the
city could also see an increase in the number of landslides or make landslides greater than usual.
Due to the number of landslide hazard zones in the city, as shown in 2, Rolling Hills may see an
increase in landslides due to changes in precipitation from climate change.
Figure 10 Changes in Intensity of Extreme Precipitation Events in Rolling Hills8
Community Sensitivity
As climate change occurs, communities will be affected to varying degrees depending on the
exposure levels as well as how sensitive the communities are to impacts. Virtually all people and
assets in a community will be affected by climate change in some way. However, it is not usually
feasible to assess the vulnerability of every population group or every asset in the community. The
sensitivity of a community depends on the aspects of the community (i.e., specific populations and
assets) most affected by the identified exposures, and how prevalent they are in the community.
As described in the Exposure section above, the most likely primary impacts of climate change that
Rolling Hills may experience include extreme heat, increases in wildfire risk and prevalence, and
drought conditions affecting water supply. This section of the Vulnerability Analysis identifies the
7 Average time between extreme events (e.g., “1 in 100-year event”)

described as days during a water year (Oct-Sept) with 2-day rainfall totals above an extreme threshold of 1.02 inches.

sensitive areas of the Rolling Hills community from the demographic and community facility
information in the Introduction section above and is based on the following categories:
Populations
Infrastructure
Buildings and Facilities
Services
Populations
The vulnerability assessment considers the following population groups that may be
disproportionally harmed by the impacts of climate change in Rolling Hills.
Children: Approximately 6.6 percent of the total population in Rolling Hills are ten years old or
younger.
Persons in poverty: This is identified for people living in households with an income below the
poverty limit, which is $26,200 for a household of four people. There are approximately 26 people in
Rolling Hills who live in poverty, or approximately 1.6 percent of the total population for whom
poverty status can be determined.
Persons with chronic health conditions: These are people who have a long-term or permanent
health condition that can create regular challenges in their day-to-day lives. These health problems
include obesity, cancer, heart disease, and arthritis. In addition, those with any kind of disability,
including mobility challenges, hearing, or vision impairments, behavioral disabilities, and challenges
living independently or taking care of themselves. Approximately 11.5 percent of the population
have identified having a disability.
Renters: These are people who live in homes that they (or the head of their household) do not own.
Approximately 24 housing units, or 4 percent of the housing units in Rolling Hills, are renter-
occupied.
Older adults: These are persons 65 years or older are more at risk for climate change impacts,
especially those living alone. 28 percent of the population of Rolling Hills are over 65 years, and 15
percent of those over 65 years live alone.
Limited English proficiency: Approximately three percent of households have identified being
limited English-speaking. Of those, a majority spoke Asian and Pacific Island languages and Spanish.
Infrastructure
The vulnerability assessment considers the following infrastructure in the city that was identified as
bring sensitive to climate change impacts.
Access Roads: These roadways are one of a few, or the only, ways in and out of some communities
or neighborhoods. The single or limited number of entry and exit points does not make the road
itself more vulnerable than other roads, but loss of these roadways can effectively cut off large
numbers of people from other areas in the Palos Verdes Peninsula and the rest of Los Angeles
County. Portuguese Bend Road and Crest Road are the primary access roads into and out of the city.
Bridle Trails: Throughout the community are over 25 miles of trails available to city residents and
non-city residents who obtain permits. The trails are maintained by the Rolling Hills Community
Association and located primarily in canyon areas.

Electrical Substations: Electrical substations are facilities that convert electricity from one voltage to
another, making it suitable for long-distance transmission or for use by homes, businesses, and
other electrical customers. There are no electrical substations located within city limits, but three
are located near the city in Rancho Palos Verdes and owned/operated by Southern California
Edison.
Electrical Utility Lines: These lines transmit and deliver electricity from Southern California Edison to
the city. The city has both underground and overhead electric utility lines.
Natural Gas Transmission Pipelines: Natural gas pipelines carry large volumes of natural gas
between communities. There are no transmissions lines in the city. One transmission line ends at
the intersection of Rolling Hills Road and Palos Verdes Drive, adjacent to city limits.
Water Reservoirs and System: The system that stores and supplies drinking water for residents.
Palos Verdes Water District of the California Water Service supplies water to Rolling Hills. There are
two California Water Service water reservoirs within the city limits.
Building and Facilities
Residential Structures: Residential structures in Rolling Hills consist of single-family dwellings and
are the main type of building in the city.
Community Facilities and Government Buildings: Community and government facilities are public
properties and are important to the residents as well as the operation of the city. Rolling Hills is a
private community. Therefore, community and government facilities are available only to its
residents, which are the Rolling Hills Community Association and City Hall.
Community Parks: Storm Hill is an open space area owned by the City which is utilized for
equestrian purposes. The City also has two equestrian rings and tennis courts.
Schools: Rancho Del Mar High School is the only school in the city
Public Safety Facilities: Public safety facilities include sheriff and fire buildings. Los Angeles County
Fire Station 56 is located within the city. The Lomita Station of the Los Angeles County Sheriff serves
the city but is not located within the city limits.
Services
Public Safety Response: Public safety services are provided by law enforcement and fire agencies.
These agencies include the Los Angeles County Sheriff and Fire Departments.
Water Services: These services involve treating and transporting water to be used by customers and
transporting and treating wastewater so it can be safely released into the environment. California
Water Service provides drinking water to the city.
Energy delivery: Energy services in Rolling Hills include electricity and natural gas delivered through
utility lines from Southern California Edison and Southern California Gas Company.
Potential Impacts
Impact vulnerability is the nature and degree to which the community is affected by a given
stressor, change, or disturbance. As climate change continues to progress, increased stress to
vulnerable community populations, infrastructure, building and facilities, and services are expected.
As described in the Exposure section above, the most likely primary impacts of climate change
355
Climate Change Vulnerability
Existing Conditions Report 27
Rolling Hills may experience include extreme heat, wildfire, and drought conditions impacting water
supply. The vulnerability of Rolling Hills to the primary exposures of climate change is discussed
below. The vulnerability scores discussed in the Vulnerability Scoring section are based on the
potential impact analysis below. Each of the vulnerable areas in the city were given a low, medium,
or high vulnerability to the potential impacts, based off the descriptions in the Vulnerability Scoring
section.
Temperature and Extreme Heat
As describe in the Exposure section above, Rolling Hills may experience a variety of impacts from
climate change, which include an increase of average annual maximum temperature between 1.8°F
and 6.6°F by the end of the century (CEC 2020) This increase in temperature may result in changes
in seasonal patterns, an increase in heat waves, drought, and potentially increased storm frequency
and intensity. Rolling Hills is expected to experience between 8 and 14 extreme heat days annually.
Overall quality of life in the city would be impacted during extreme heat events as outdoor activities
would be limited and overall comfort reduced.
The potential direct and indirect impacts to community populations, infrastructure, building and
facilities, and services are described below.
Populations
The vulnerable populations discussed above that are most at risk to extreme heat impacts from
climate change are older adults, individuals with chronic conditions such as heart and lung disease,
diabetes, and mental illnesses, children, and those who are economically disadvantaged.
The primary vulnerable population to temperature increases and extreme heat in Rolling Hills is
older adults, as 28 percent of the city’s population is over 65 years. Older adults do not adjust as
well as young people to sudden changes in temperature and are more likely to have medical
conditions that can worsen with extreme heat (CDC 2017a). Older adults who are living along are
even more at risk as the actions necessary to mitigation extreme heat are more difficult alone.
Getting water, changing clothes, showering, or turning on the air conditioner may be more difficult
for older adults with physical disabilities and do not have a living partner to assist them. Children are
also at risk to extreme heat impacts, especially those under the age of four, due to their less-
developed physiology, immune system, and dependence on others (CDC 2019).
Extreme heat can be highly dangerous to persons with chronic health conditions, because very high
temperatures can exacerbate diabetes, cardiovascular conditions, respiratory ailments, and other
diseases. Some of these people have weakened immune systems which can make them more likely
to contract illnesses and vulnerable to human health hazards. In addition, they may be taking
medications that make the effects of extreme heat worse (CDC 2017b).
While there are not many households in poverty in the city, those who are have limited financial
resources to upgrade their homes and use air conditioning to better resist extreme heat.
Each of the vulnerable populations has a high potential impact from extreme heat.
Infrastructure
Extreme heat and temperature increase due to climate change would not directly impact
infrastructure in Rolling Hills. Indirect impacts on electrical substations and utility lines could occur
from increased use of the system from running air conditioners, leading to power outages in the
356
City of Rolling Hills
Rolling Hills General Plan Safety Element
28
city. In addition, indirect impacts to the water system through increased evaporation or water use
could occur. These infrastructure facilities would have a medium potential impact from extreme
heat.
Building and Facilities
Extreme heat and temperature increase due to climate change
would not directly affect buildings or facilities in Rolling Hills. Extreme heat and temperature
increases could impact the ability for residents to enjoy community park facilities. In addition,
extreme heat could create wildfire conditions which could indirectly impact all buildings and
facilities within the city. Overall, there is a low potential impact from extreme heat to City buildings
and facilities.
Services
The important services discussed above that are most at risk to extreme heat impacts from climate
change are water services and energy delivery.
High temperatures would contribute to a reduced water supply. For instance, higher temperatures
will melt the Sierra snowpack earlier and drive the snowline higher. In addition to a reduction in
precipitation falling as snow, higher temperatures would result in less snowpack to supply water to
California users (CNRA 2009). Increased temperatures could therefore result in decreased potable
water supply for the city which relies on imported water from the State Water Project and Colorado
River water (Cal Water 2016). Therefore, there is a medium potential impact for high temperatures
and drought on the city.
Long periods of intense heat may result in increased use of electricity for home cooling purposes
that could tax the overall electrical system and result in electricity restrictions or blackouts. During
extreme heat events in August 2020, California had its first rolling blackouts since 2001. Therefore,
the city will experience greater potential for power outages due to climate change and has a
medium potential impact.
Storms/Extreme Weather and Drought
As mentioned in the Exposure section above, the storm and extreme weather projections for Rolling
Hills show variability, with some models projecting little to no change while others project increased
intensity. This could result in impacts to community populations, infrastructure, building and
facilities, and services, particularly related to temporary flooding and landslides which can be
triggered from intense rainfall events. The city currently has a less than 0.2 percent annual chance
to be inundated by flood waters as a result of a storm event (FEMA 2008). Increases in intense
precipitation could result in slope failures in landslide prone areas shown in Figure 2, including the
existing Flying Triangle Landslide area.
As discussed in the Exposure section above, Rolling Hills is not expected to experience substantial
changes in average precipitation. However, the city receives its water from the Colorado River and
State Water Project from northern California, and extended drought scenario is predicted for these
areas, which equates to 78 percent of the historic median annual precipitation. Therefore, areas
that supply water to Rolling Hills and other jurisdictions are expected to see a 22 percent reduction
of their water supply, which could reduce the amount of potable water available for delivery to the
city.
357
Climate Change Vulnerability
Existing Conditions Report 29
Populations
The city’s older adults and those with chronic health conditions are the populations in Rolling Hills
that are more at risk of injury and or death resulting from minor floods or fallen trees created by
more intense storms induced by climate change. Indirect impacts to these populations from impacts
to the transportation system could include reduced access to emergency response and health
centers for those who need consistent medical care. There is a medium potential for impacts to
these vulnerable populations.
Infrastructure
Critical infrastructure most at risk in Rolling Hills to minor flooding impacts and landslides from
increased storms would be access roads, bridle trails, electrical utility lines, and water systems.
Because Portuguese Bend Road and Crest Road are critical for access to and evacuation from the
city, any damage or closure can effectively isolate areas of the city, potentially creating severe
health and safety risks. Bridle trails are predominantly located in canyon areas, which would be
more susceptible to flooding and landslides. Landslides could impact utilities, as seen in the existing
Flying Triangle Landslide area, which has moved utility lines above ground in certain areas due to
the continuous movement of the earth in this area. Due to the limited accessibility of the city, there
is a medium potential impact for access roads and bridle trails and a low potential impact for the
remaining vulnerable infrastructure.
Building and Facilities
Buildings and facilities most at risk from impacts of more intense storms would be residential
structures and community parks. The proper functioning residential septic systems could be
impacted by more intense rainfall and minor flooding. In addition, landslides could be triggered as
indirect impacts from more intense storms and rainfall. Residential structures located in landslide
hazard areas shown in Figure 2 could be impacted. In addition, the Storm Hill open space area is an
important facility in the city and is also located in a landslide area. Due to the variability in weather
projections, there is a low potential impact for buildings and facilities.
Services
Increased storm intensity and drought conditions from climate change could impact public safety
response, energy delivery and water services in the city. Emergency response systems could be
impacted from flooding or landslides within or outside of city limits, which could restrict the ability
for emergency response to access the city and impact response times.
More intense storms could adversely affect electricity delivery from Southern California Edison from
power outages caused by downed electrical utility lines from wind of landslide events. In addition,
water service from the California Water Service Palos Verdes District could be affected by increased
drought conditions throughout the state. There is a medium potential impact for buildings and
facilities.
Wildfire
Wildfires in Los Angeles County are projected to increase under all emissions and population
scenarios. As discussed in the Exposure section above, wildfire hazards to the city are widespread
and wildfire conditions are expected to be exacerbated by a range of factors including droughts,
358
City of Rolling Hills
Rolling Hills General Plan Safety Element
30
more severe winds, wildfire fuel (i.e., dry vegetation), and hotter and drier landscapes from
increased temperatures and extreme heat.
Populations
The vulnerable populations discussed above that are most at risk to increases in wildfire from
climate change are older adults, persons in poverty, and persons with chronic health conditions.
Older adults are almost three times more likely to die in a fire than the overall population (USFA
2017), and typically have increased mobility issues or mental health. Therefore, older adults,
especially those in the city living alone, have more difficulties evacuating to safe areas when there is
a need. Those in Rolling Hills with limited financial resources are more unlikely to retrofit their
homes to better resist climate-related hazards such as wildfires.
In addition to direct impacts, indirect impacts such as poor air quality also creates public health
hazards to the city. Recent California wildfires in August and September 2020 had areas of California
recording the worst air quality in the world and highlighted the hazards of secondary impacts from
wildfires, which could impact the city from fires throughout the State. Older adults and individuals
with chronic health conditions are likely to be impacted most by these secondary impacts. Also,
those with limited finances or without air conditioning would be impacted by secondary smoke
impacts that occur during local and regional wildfires. There is a high potential for wildfire impacts
on the vulnerable populations.
Infrastructure
All city infrastructure is located in a VHFHSZ. The critical infrastructure most at risk to increased
wildfire impacts would be access roads, bridle trails, above ground electrical utility lines, and water
systems. Portuguese Bend Road and Crest Road are critical for access to and evacuation from many
areas of the city. Wildfires may not significantly damage the infrastructure, but they could result in
closure or the inability to travel on them during wildfire events, which can isolate areas of the city
and create severe health and safety risks. There is a high potential for impacts to access roads from
wildfires.
Wildfires are unlikely to substantially damage trails directly, but they can force widespread trail
closures which are an important asset to the community. Above ground electrical lines are also at
risk from wildfires and could impact electricity services to residents in Rolling Hills. Water systems
could be directly affected by wildfires in addition to indirect impacts from water use from
firefighting activities and peak load water supply in remote portions of the city. There is a medium
potential for impact to these infrastructures.
Building and Facilities
As discussed under Hazards of Concern section, all of Rolling Hills is designated a VHFHSZ.
Therefore, all buildings and facilities within the city are at risk of increased wildfires caused by
climate change. The greatest potential impact of life and well-being would be to residential
structures, which are the primary structures in the city. In addition, impacts to Rolling Hills
Community Association and City Hall structures would impact community functions and government
services. There is a high potential for impact to buildings and facilities from wildfire.

Existing Conditions Report 31
Services
Energy delivery, specifically electricity delivery, could be impacted from increased wildfires. Direct
impacts to Southern California Edison electricity transmission infrastructure could impact power in
the city. In addition, utility companies have begun shutting off power to areas to avoid wildfires
during times when weather creates high wildfire risk. In addition, public safety services could be
strained during wildfire events, which are expected to increase. There is a medium potential for
impacts to services in the city from wildfire.
Adaptive Capacity
Adaptive capacity is the current ability to cope with climate change impacts to community
populations and assets (Cal OES 2020). Specifically, adaptative capacity is the ability to mitigate the
potential impacts and damages or take advantage of the opportunities from climate change. Many
communities have adaptive capacity in the form of policies, plans, programs, or institutions. Rolling
Hills has actively taken steps to increase the city’s adaptive capacity, which include preparing a
community wildfire protection plan, hazard mitigation plan, undergrounding utility lines, and
adopting strict new building standards. Table 5 lists various guiding documents, projects, plans, and
policies that have an underlying emphasis on adaptive capacity in the city.

Rolling Hills has a number of plans and policies specific to wildfire hazards. The city’s recently
adopted the Community Wildfire Protection Plan that includes fire mitigation strategies and
evacuations strategies specific for the city. In addition, the Hazard Mitigation Plan provides an
analysis of historical hazards, a local hazard assessment, hazard impacts on the community, and
recommended mitigation strategies. The City requires the undergrounding of utility lines with
specific home upgrades and has a reimbursement program for utility pole replacement. In addition,
building code requirements for development within VHFHSZ, such as Class A roofing, would help
reduce wildfire impacts to structures in the city.
360

The Rolling Hills Building and Zoning Codes include controls on development on steep slopes and
canyon bottoms. In addition, development requires proof of stability of the property through
geotechnical reports and only a percentage of each lot can be disturbed.
The Palos Verdes Water District’s Urban Water Management Plan (UWMP) provides water supply
and demand projections and includes a climate change analysis. The 2015 UWMP projected that
water supply reductions to the District due to climate change would be small for through the end of
the century. In addition, the UWMP includes a water shortage contingency plan and demand
reduction measures in the event water supply to the District is impacts from drought due to climate
change.
In addition, the city’s population has a high degree of adaptive capacity due to the high levels of
home ownership, low poverty levels, and high average income levels. These characteristics improve
resident’s ability to upgrade their homes and come back from potential impacts to their property
from wildfire and extreme storm events.
Vulnerability Scoring
Vulnerability scores are based on the combination of potential impacts from climate hazards and
adaptive capacity in order to identify the climate vulnerabilities in the city to address with additional
adaptation strategies. A vulnerability score was determined for each sensitivity area based on the
potential impacts and adaptive capacity from climate change in the city. Vulnerability was accessed
on a scale from 1 to 5:
V-1: Minimal Vulnerability
V-2: Low Vulnerability
V-3: Moderate Vulnerability
V-4: High
V-5: Severe
Cal OES recommended the following scoring rubric to determine the vulnerability score for the
potential impacts and adaptive capacity.
Low Potential Impact: Impact is unlikely based on projected exposure; would
result in minor consequences to public health, safety, and/or other metrics of concern
Medium Potential Impact: Impact is somewhat likely based on projected exposure; would
result in some consequences to public health, safety, and/or other metrics of concern
High Potential Impact: Impact is highly likely based on projected exposure; would result in
substantial consequences to public health, safety, and/or other metrics of concern
Low Adaptive Capacity: The population or asset lacks capacity to manage climate impact; major
changes would be required
Medium Adaptive Capacity: The population or asset has some capacity to manage climate
impact; some changes would be required
High Adaptive Capacity: The population or asset has high capacity to manage climate impact;
minimal to no changes are required
Table 6 shows how the final vulnerability score was determined. To summarize, potential impacts
from climate change that are highly likely to occur in the city based on projected exposure would
361
Climate Change Vulnerability
Existing Conditions Report 33
create a high vulnerability score. However, if the city has a high adaptive capacity to manage the
impact, then the overall vulnerability score would be reduced.
Table 6 Vulnerability Score Matrix Potential Impacts High V-3 V-4 V-5
Medium V-2 V-3 V-4
Low V-1 V-2 V-3
High Medium Low
Adaptive Capacity
The vulnerability scoring for the identified population and assets for each climate impact is included
below in Table 7 and based on Cal OES California Adaptation Planning Guide. For those populations
and assets that are not anticipated to be impacted directly or indirectly from the identified climate
impacts, no vulnerabilty score or color is provided. For example, drought impacts on children were
determined to not be a threat in Rolling Hills.
For the purposes of this vulnerability assessment, a score of V-4 or V-5 is considered significant.
Populations and assets that score at least a V-4 for one or more exposures are considered
substantially vulnerable. As shown in Table 7, the potential impacts from climate change the city’s
population and assets are most vulnerable to are wildfire, extreme heat, and landslides. Vulnerable
populations such as older adults, residents with chronic health conditions, and those with financial
trouble are most at risk to extreme heat and wildfire impacts and are substantially vulnerable to
climate change impacts in the city. Access roads and residential structures are also the most
vulnerable to wildfire and landslide impacts from climate change. Overall, climate change impacts
on wildfire are the greatest potential impact to the city. While the City has adopted a significant
number of adaptation strategies related to wildfire impacts, because they were recently adopted
and some of the strategies were included as recommendations, it will be important to determine
and monitor if implementation is occurring and which recommendations should be included in the
Safety Element update.
This vulnerability assessment and the results in Table 7 will be used to identify specific policies and
implementable strategies for adapting to climate change in the Safety Element, thus making the
Rolling Hills community more resilient.

Summary of Issues and Opportunities
Existing hazards of concern in the city that should be a major focus of the Safety Element update
include landslide and wildfire hazards. In addition, emergency response and evacuation should be a
focus due to the city’s accessibility issues. Climate change is expected to increase potential hazards
the city experiences. From the vulnerability analysis, the city is most vulnerable to wildfire impacts,
extreme heat, and landslides impacts from climate change.
Hazards of Concern and Community Sensitivity
While there are a number of hazards that could impacts the city, the following are hazards of
concern that pose the greatest challenge to the city.
Wildfire
The greatest hazard of concern for the city is wildfire as the entire city limits are within a VHFHSZ
and the city contains many remote areas and limited evacuation routes. Some existing residential
and accessory structures are not built to current standards that apply to VHFHSZ and as a result
many of these structures may require mitigation and retrofit to reduce this potential threat. The
area’s most vulnerable to wildfire impacts include older adults, persons with chronic health
conditions, residential structures, government and community buildings, and access roads.
Landslides
Landslides are also a major concern for the city, whether they are earthquake induced, induced
from high precipitation events, or occur due to the underlying soil conditions. Existing landslides are
impacting the southern portion of the city. Climate change has the potential to create more
landslide events if Rolling Hills experiences more intense storms and precipitation events. The area’s
most vulnerable to landslide impacts include access roads, residential structures, and community
parks.
Extreme Heat
The city is expected to see increases in the number and length of extreme heat days and events due
to climate change, which could impact vulnerable people in the city and lead to increased wildfire
risks. The area’s most vulnerable to extreme heat impacts from climate change include older adults,
persons with chronic health conditions, and the energy system.
Opportunities
The need to further analyze evacuation routes and access is one of the most recent changes in
Safety Element requirements. These new requirements focus on the identification of areas where
routes are lacking or inadequate. A key opportunity for the Safety Element update is address
specific evacuation needs.
The City has recently adopted a number of planning documents, such as the Hazard Mitigation Plan
and Community Wildfire Protection Plan, that seek to reduce the risk of hazards in the city. Many of
the strategies included in these documents are recommendations and are used for educational
purposes. An opportunity for the Safety Element update would be to include the recommendations
365
Summary of Issues and Opportunities
Existing Conditions Report 37
as implementation tools for the Safety Element and to conduct outreach with the community to
determine if community preparedness is occurring.
The California Legislature recently adopted Senate Bill 182 (SB 182) and is awaiting Governor
approval. SB 182 would require the Safety Element to include a comprehensive retrofit strategy as
necessary to reduce the risk of property loss and damage during wildfires. Additionally, in order to
reduce development pressures in the VHFHSZ through the Regional Housing Needs Allocation
process, SB 182 requires a lower proportion of state housing allocation to jurisdictions that meet
specified conditions. The City should monitor and incorporate these elements as necessary.

SECTION 1.0 – INTRODUCTION
1.1 DRAFT INITIAL STUDY / NEGATIVE DECLARATION
An Initial Study Negative Declaration (IS/ND) was prepared for both the Housing Element Update and
Safety Element Update for the City of Rolling Hills. On January 13, 2022, the City of Rolling Hills circulated
a Draft IS/ND to public agencies and the general public. In accordance with the California Environmental
Quality Act (CEQA) Section 21091 and State CEQA Guidelines Section 15073, a 30-day public review period
for the Draft IS/ND was provided from January 13, 2022 to February 12, 2022.
The City has not yet received comments back from the California Department of Housing and Community
Development (HCD) on the Housing Element Update, and does not wish to approve the Housing Element
Update without such comments. The City has removed the Housing Element Update from the Project (and
associated IS/ND). The changes to the IS/ND do not affect the overall conclusions of the environmental
document; the analysis of the Safety Element Update is wholly bounded by the analysis and findings in
the previously circulated Draft IS/ND. An errata has been prepared to clarify and modify the Project.
1.2 AVAILABILITY OF THE NOI AND IS/ND
The Notice of Intent (NOI) and the IS/ND were available for review at the following locations:

SECTION 2.0 – PROJECT DESCRIPTION AND SETTING
2.1 INTRODUCTION
The City of Rolling Hills (City) is a rural, equestrian residential community, consisting entirely of large lot
residential parcels of one acre or more. The community encompasses 2.99 square miles of land
(approximately 1,910 acres) on the Palos Verdes Peninsula in the County of Los Angeles (Figure 2.2-1:
Project Location). The City’s General Plan was drafted and adopted in 1990. The City is proposing updates
to the Safety Element of the General Plan, one of the six elements.
The Safety Element Update (SEU), (Appendix A of the Draft IS/ND) provides the City’s goals, policies, and
actions to minimize the hazards to safety in and around the City. The SEU evaluates natural and human-
caused safety hazards that affect existing and future development and provides guidelines for protecting
the community from harm. The SEU describes existing and potential future conditions and sets policies
for improved public safety. The goal of the SEU is to reduce the risk of injury, death, property loss, and
other hardships to acceptable levels. A detailed description of the update is provided below.
2.2 SAFETY ELEMENT UPDATE
2.2.1 Background
Throughout its history as a city, the City has dealt with various natural hazards, including earthquakes,
wildfires, droughts, and land movement. Developments in high landslide areas have occurred, and the
City has been identified as being located in a Very High Fire Hazard Severity Zone (VHFHSZ). As a result,
the City has amended its building and safety codes to include special requirements such as fire-rated
materials for new construction and a requirement for geotechnical studies in active fault zones.
2.2.2 Safety Element Overview
The City’s SEU addresses hazards of concern relevant to the City and provides goals, policies, and
implementation measures to minimize these hazards. Figures 2 through 6 of the SEU show exact locations
of these hazards, which are described in the following paragraphs.
Landslide Hazards
Much of the existing development in the City is located on hilly terrain and has a greater potential to
experience landslide hazards. Many of the canyons in the City exhibit steep slopes with little vegetation
coverage, leaving them susceptible to slope failure.
Seismic Hazards
The City is in a seismically active region of southern California. The last major earthquake in the Los
Angeles area was the 5.1 magnitude La Habra earthquake in 2014. The City is within 50 miles of the
Whittier fault, Newport-Inglewood fault, Palos Verdes fault, Malibu Coast fault, Cabrillo fault, Santa
Monica fault, and Redondo Canyon fault. Analysis of seismic data from the region indicates that the
Whittier and Newport-Inglewood faults may generate a maximum credible earthquake of magnitude 7.2
and 7.4, respectively. The earthquake shaking potential for the City is moderate. A number of seismically
active faults are present in the City and region; however, none are active faults with the potential for

City of Rolling Hills Safety Element Update
Rolling Hills, Los Angeles County, California

ground rupture, defined by the Alquist-Priolo Earthquake Fault Zoning Act and delineated by California
Geological Survey. The City has a low potential for liquefaction, as the subsurface soils generally lack
saturated alluvial deposits and thick, granular soils.
Flooding
The City is not in any immediate risk from flooding caused by overflowing water bodies or heavy rains.
However, runoff and minor flooding pose a risk if drainage systems fail along canyon bottoms, where
natural drainage leads. Due to dam locations and the topography of the area, the inundation areas do not
enter or affect any portion of the City.
Wildland and Urban Fires
The entire City is designated a Very High Fire Hazard Severity Zone (VHFHSZ) by the California Department
of Forestry and Fire Protection (CAL FIRE 2011). The terrain in the City is composed of several large and
steep canyons that limit and challenge vegetation management and present conditions where a fire can
quickly travels up and downslope to nearby homes. Due to the rural nature and large residential lots,
many homes are surrounded by more substantial vegetation and dense brush than in more suburban
settings.
Hazardous Materials
According to the Department of Substances Control (DTSC 2021), no hazardous waste sites or facilities are
present in the City. The City and surrounding area do not contain heavy industrial uses that would create
a hazardous material risk in the event of a spill, release, or natural disaster.
2.2.3 Goals and Policies
The SEU is a policy document; no actual development or rezoning of parcels is included as part of the
approval. In addition to goals and policies, the SEU includes implementation measures for action items
for the City. The goals, policies, and implementation for hazard mitigation, community communication,
and climate change adaptation and resilience are listed at the end of the SEU.

SECTION 3.0 – FINDINGS
An IS / ND was prepared to assess the proposed Project's potential impacts on the environment and the
significance of those impacts. Based on this IS / ND, it was determined that the proposed Project would
not have any significant impacts on the environment. This conclusion is supported by the following
findings:
No potential was found for adverse impacts on Aesthetics, Agriculture, Air Quality, Biological
Resources, Cultural Resources, Energy, Geology and Soils, Greenhouse Gases, Hazards and
Hazardous Materials, Hydrology, Land Use and Planning, Mineral Resources, Noise, Population
and Housing, Public Services, Recreation, Transportation, Utilities and Service Systems, Tribal
Cultural Resources, and Wildfire associated with the Proposed Project.
The proposed Project will not have the potential to substantially degrade the quality of the
environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife
population to drop below self-sustaining levels, threaten to eliminate a plant or animal
community, substantially reduce the number or restrict the range of an endangered, rare or
threatened species or eliminate important examples of the major periods of California history or
prehistory with the implementation of the recommended mitigation.
The proposed Project will not have impacts that are individually limited but cumulatively
considerable.
The proposed Project will not have environmental effects which will cause substantially adverse
effects on human beings, either directly or indirectly

SECTION 5.0 – RESPONSE TO COMMENTS
CEQA Guidelines Section 15204 (b) outlines parameters for submitting comments and reminds persons
and public agencies that the focus of review and comment of negative declarations should be, “on the
proposed finding that the project will not have a significant effect on the environment. If persons and
public agencies believe that the project may have a significant effect, they should: (1) Identify the specific
effect; (2) Explain why they believe the effect would occur, and; (3) Explain why they believe the effect
would be significant.”
CEQA Guidelines Section 15204 (c) further advises, “Reviewers should explain the basis for their
comments, and should submit data or references offering facts, reasonable assumptions based on facts,
or expert opinion supported by facts in support of the comments. Pursuant to Section 15064, an effect
shall not be considered significant in the absence of substantial evidence.” Section 15204 (d) also states,
“Each responsible agency and trustee agency shall focus its comments on environmental information
germane to that agency’s statutory responsibility.” Section 15204 (e) states, “This section shall not be
used to restrict the ability of reviewers to comment on the general adequacy of a document or of the lead
agency to reject comments not focused as recommended by this section.”
In accordance with Public Resources Code 21092.5 (b) of the CEQA Guidelines, the lead agency shall notify
any public agency which comments on a negative declaration of the public hearing or hearings, if any, on
the project for which the negative declaration was prepared. If notice to the commenting public agency
is provided pursuant to Section 21092, the notice shall satisfy the requirement of this subdivision.
5.1 COMMENTS AND RESPONSES TO COMMENTS
Written comments on the Draft IS / ND are reproduced on the following pages, along with responses to
those comments. To assist in referencing comments and responses, the letters are coded using numbers
(e.g., Comment Letter 1) and each issue raised in the comment letter is assigned a number that correlates
with the letter (e.g., 1-1, 1-2, 1-3, etc.).

RESPONSE TO COMMENT LETTER 1
Commenter: Miya Edmonson, IGR/CEQA Branch Chief, California Department of Transportation
Date of Letter: January 27, 2022
Response to Comment 1-1: The commenter acknowledges receipt of the environmental document
and discusses the Project components. However, it should be noted that clarifications and insignificant
modifications to the negative declaration have been made to remove the Housing Element Update part
of the Project. The comment also provides population and housing information regarding the City of
Rolling Hills. No response is required.
Response to Comment 1-2: The commenter discusses the shift in transportation analysis as a result
of Senate Bill 743 which utilizes vehicle miles traveled (VMT) as the analysis metric as required for CEQA
projects and notes the challenges that the region faces in identifying viable solutions to alleviating
congestion on state and local facilities. The commenter suggests use of road diets, complete streets, and
use of pedestrian safety measures to increase road safety and notes the environmental report should
ensure all modes are served well by planning and development activities. This comment is noted,
and no further response is required.
Response to Comment 1-3: The commenter encourages the lead agency to use Transportation
Demand Management strategies for future specific projects to support transit and pedestrian services,
while providing reference manuals for these strategies. This comment is noted, and no further response
is required.
Response to Comment 1-4: The commenter acknowledges the lack of public roads or streets in the
City and notes the City’s circulation infrastructure does not support high volume trips. The commenter
also notes impacts associated with future development would require project-specific mitigation
measures. Any potentially significant environmental impacts identified from future development would
be addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City.
Response to Comment 1-5: The commenter concludes the letter and provides contact information
for questions related to the letter. This comment is noted, and no further response is required.

RESPONSE TO COMMENT LETTER 2
Commenter: Erinn Wilson-Olgin, Environmental Program Manager I, South Coast Region, California
Department of Fish and Wildlife
Date of Letter: February 4, 2022
Response to Comment 2-1: The commenter notes that California Department of Fish and Wildlife
(CDFW) has reviewed the proposed Project and Negative Declaration. The commenter accurately notes
that they are a Trustee Agency per CEQA Guidelines Section 15386 subdivision (a). The commenter also
notes that they are submitting comments as a Responsible Agency; however, per CEQA Guidelines Section
15381, a responsible agency is a public agency with discretionary approval authority over a portion of a
CEQA project (e.g., required permits). The commenter also notes that CDFW’s regulatory authority is
derived from the potential need for a lake and streambed alteration agreement or take permit; however,
neither will be required for the Project. As the proposed Project requires no permits, there are no
responsible agencies. However, it should be noted that clarifications and insignificant modifications to the
negative declaration have been made to remove the Housing Element Update part of the Project. None
of the clarifications and modifications are considered “substantial revisions” because they do not show
that the Project has a new, avoidable significant effect and the City has determined that project revisions
are not required to reduce potential effects to less than significant. None of the clarifications and
modifications substantially modify the analysis or conclusions of the IS/ND, but they instead merely
remove discussion of the Housing Element Update. As noted above, the clarified and modified Project
would continue to result in no impacts without any need for mitigation.
Response to Comment 2-2: The commenter provides a description of the Project. However, it
should be noted that clarifications and insignificant modifications to the negative declaration have been
made to remove the Housing Element Update part of the Project. No response is required.
Response to Comment 2-3: The commenter introduces their comments and provides
recommendations regarding perceived impacts tied to future development. The commenter also
proposes potential mitigation measures for protection of biological resources including wildlife and
plant species that exist within the City.
The City is proposing an updates to the Safety Element of the General Plan, one of the six General Plan
elements that cover long-range planning for the community’s growth and development.
CEQA Guidelines Section 15126.4 notes that mitigation measures are not required for effects, which are
not found to be significant. Since the Project is the adoption of a policy document and not an application
for development of any particular parcel or site in the City or change in zoning, no impacts to biological
resources were identified and no mitigation is required. However, it should be noted that clarifications
and insignificant modifications to the negative declaration have been made to remove the Housing
Element Update part of the Project. None of the clarifications and modifications are considered
“substantial revisions” because they do not show that the Project has a new, avoidable significant effect
and the City has determined that project revisions are not required to reduce potential effects to less than
significant. None of the clarifications and modifications substantially modify the analysis or conclusions of
the IS/ND, but they instead merely remove discussion of the Housing Element Update. As noted above,
the clarified and modified Project would continue to result in no impacts without any need for mitigation.

Response to Comment 2-4: The commenter raised concern regarding potential impacts to the coastal
California Gnatcatcher and noted that 14 of the 20 identified sites overlap with habitat for the species.
The commenter also provided suggested mitigation measures to reduce perceived impacts.
All future projects would be treated as individual projects and may be subject to specific environmental
analysis including potential impacts to the coastal California gnatcatcher. All future projects, especially
the 14 sites identified with habitat for the species, would be required to address any potential impacts
to the species. As necessary, future projects will analyze direct, indirect, and cumulative biological
impacts and will include specific mitigation or avoidance measures as suggested to offset impacts.
Additionally, CEQA Guidelines Section 15126.4 notes that mitigation measures are not required for
effects, which are not found to be significant. Since the Project is the adoption of a policy document and
not an application for development of any particular parcel or site in the City or change in zoning, no
impacts to the coastal California gnatcatcher were identified and no mitigation is required. However, it
should be noted that clarifications and insignificant modifications to the negative declaration have been
made to remove the Housing Element Update part of the Project. None of the clarifications and
modifications are considered “substantial revisions” because they do not show that the Project has a
new, avoidable significant effect and the City has determined that project revisions are not required to
reduce potential effects to less than significant. None of the clarifications and modifications
substantially modify the analysis or conclusions of the IS/ND, but they instead merely remove discussion
of the Housing Element Update. As noted above, the clarified and modified Project would continue to
result in no impacts without any need for mitigation.
Response to Comment 2-5: Comments were provided regarding impacts on streams and associated
natural communities. The commenter notes that the City consists of canyons of the San Pedro Hills; and
within these canyons are streams, whether ephemeral, intermittent, or perennial. The commenter also
provides suggested mitigation measures and recommendations regarding perceived impacts to these
noted streams.
All future projects would be treated as individual projects and may be subject to specific environmental
analysis including potential impacts on streams. All future projects, especially those in areas with streams
(ephemeral, intermittent, or perennial) would be required to prepare hydrology reports and / or obtain
appropriate permits in order to evaluate potential impacts on these watercourses and permit any
potential impacts. As necessary, future projects will analyze direct, indirect, and cumulative biological
impacts and will include specific mitigation or avoidance measures as suggested to offset impacts.
Additionally, CEQA Guidelines Section 15126.4 notes that mitigation measures are not required for
effects, which are not found to be significant. Since the Project is the adoption of a policy document and
not an application for development of any particular parcel or site in the City or change in zoning, no
impacts to streams were identified and no mitigation is required. However, it should be noted that
clarifications and insignificant modifications to the negative declaration have been made to remove the
Housing Element Update part of the Project. None of the clarifications and modifications are considered
“substantial revisions” because they do not show that the Project has a new, avoidable significant effect
and the City has determined that project revisions are not required to reduce potential effects to less than
significant. None of the clarifications and modifications substantially modify the analysis or conclusions of
the IS/ND, but they instead merely remove discussion of the Housing Element Update. As noted above,
the clarified and modified Project would continue to result in no impacts without any need for mitigation.

Response to Comment 2-6: The commenter raises concerns regarding potential impacts to nesting
birds and noted that all 20 of the sites identified for potential development contain vegetation suitable
as habitat for nesting birds and raptors. The commenter also provided suggested mitigation measures
for perceived impacts to nesting birds.
All future projects would be treated as individual projects and may be subject to specific environmental
analysis, including potential impacts to nesting birds and / or raptors. All future projects, especially those
removing potential habitat for bird and raptor species, would be required to address any potential
impacts. As necessary, future projects will analyze direct, indirect, and cumulative biological impacts and
will include specific mitigation or avoidance measures as suggested to offset impacts. Additionally, CEQA
Guidelines Section 15126.4, notes that mitigation measures are not required for effects, which are not
found to be significant. Since the Project is the adoption of a policy document and not an application for
development of any particular parcel or site in the City or change in zoning, no impacts to birds were
identified and no mitigation is required. However, it should be noted that clarifications and insignificant
modifications to the negative declaration have been made to remove the Housing Element Update part
of the Project. None of the clarifications and modifications are considered “substantial revisions” because
they do not show that the Project has a new, avoidable significant effect and the City has determined that
project revisions are not required to reduce potential effects to less than significant. None of the
clarifications and modifications substantially modify the analysis or conclusions of the IS/ND, but they
instead merely remove discussion of the Housing Element Update. As noted above, the clarified and
modified Project would continue to result in no impacts without any need for mitigation.
Response to Comment 2-7: The commenter raises concern regarding potential impacts to bats
and noted that all 20 of the sites identified for potential development contain vegetation suitable
roosting habitat for bats. The commenter also provided suggested mitigation measures for perceived
impacts to bat species.
All future projects would be treated as individual projects and may be subject to specific environmental
analysis, including potential impacts to bats. All future projects, especially those removing potential
roosting habitat for bats, would be required to address any potential impacts to the species. As
necessary, future projects will analyze direct, indirect, and cumulative biological impacts and will include
specific mitigation or avoidance measures as suggested to offset impacts. Additionally, CEQA Guidelines
Section 15126.4 notes that mitigation measures are not required for effects, which are not found to be
significant. Since the Project is the adoption of a policy document and not an application for
development of any particular parcel or site in the City or change in zoning, no impacts to bats were
identified and no mitigation is required. However, it should be noted that clarifications and insignificant
modifications to the negative declaration have been made to remove the Housing Element Update part
of the Project. None of the clarifications and modifications are considered “substantial revisions”
because they do not show that the Project has a new, avoidable significant effect and the City has
determined that project revisions are not required to reduce potential effects to less than significant.
None of the clarifications and modifications substantially modify the analysis or conclusions of the
IS/ND, but they instead merely remove discussion of the Housing Element Update. As noted above, the
clarified and modified Project would continue to result in no impacts without any need for mitigation.
Response to Comment 2-8: The commenter provides further recommendations that information
developed in CEQA documents be included in databases (i.e., California Natural Diversity Database) for
use in future CEQA documents. Additionally, the commenter recommends that the City include the
411
City of Rolling Hills Safety Element Update
Rolling Hills, Los Angeles County, California
Chambers Group, Inc.
21330
43
mitigation measures mentioned in the comment letter and provide a Mitigation Monitoring and
Reporting Program (MMRP).
Any future development would provide information to appropriate databases as necessary. Additionally,
any potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. As previously noted, CEQA Guidelines Section 15126.4 notes that
mitigation measures are not required for effects, which are not found to be significant. Since the Project
is the adoption of a policy document and not an application for development of any particular parcel or
site in the City or change in zoning, no impacts were identified and no mitigation is required. However, it
should be noted that clarifications and insignificant modifications to the negative declaration have been
made to remove the Housing Element Update part of the Project. None of the clarifications and
modifications are considered “substantial revisions” because they do not show that the Project has a
new, avoidable significant effect and the City has determined that project revisions are not required to
reduce potential effects to less than significant. None of the clarifications and modifications
substantially modify the analysis or conclusions of the IS/ND, but they instead merely remove discussion
of the Housing Element Update. As noted above, the clarified and modified Project would continue to
result in no impacts without any need for mitigation.
Response to Comment 2-9: The commenter notes that the proposed Project is required to pay the
CDFW filing fees. No development projects are proposed at this time or with implementation of the
Project. The Project is the adoption of the Safety Element Update. The SEU is a policy document and
does not include any changes to land use designations, zoning, building heights and intensities, or
residential densities. Therefore, the Project is the adoption of a policy document and not an application
for development of any particular parcel or site in the City. Nevertheless, as directed by the CDFW, filing
fees will be submitted at the time the Notice of Determination is filed.
Response to Comment 2-10: The commenter concludes the comment letter and provides references
and attachments associated with the comment letter. The attachments have been reviewed as part of
the responses to comments as above, and no further response is required.

SECTION 6.0 – ERRATA TO THE DRAFT NEGATIVE DECLARATION
An errata was prepared for the Draft IS/ND and is included as Appendix A of this document. The changes
to the IS/ND do not affect the overall conclusions of the environmental document; the analysis of the
environmental impacts of the Safety Element Update are fully covered in the previously circulated Draft
IS/ND. The changes that have been made to the Draft IS/ND in the errata do not constitute a “substantial
revision” to the IS/ND because the revisions (1) do not identify a new, avoidable significant effect and
mitigation measure or project revisions that must be added in order to reduce the effect to insignificance;
or (2) do not result in a change to any mitigation measures that were previously disclosed (none were).
(State CEQA Guidelines, section 15073.5.) Because the project revisions do not result in any new
avoidable significant effects, recirculation is not required. (Ibid.) The errata was prepared to clarify and
modify the Project.

BACKGROUND
An Initial Study Negative Declaration (IS/ND) was prepared for both the Housing Element Update and
Safety Element Update for the City of Rolling Hills. On January 13, 2022, the City of Rolling Hills circulated
a Draft IS/ND to public agencies and the general public. In accordance with the California Environmental
Quality Act (CEQA) Section 21091 and State CEQA Guidelines Section 15073, a 30-day public review period
for the Draft IS/ND was provided from January 13, 2022 to February 12, 2022.
The City has not yet received comments back from the California Department of Housing and Community
Development (HCD) on the Housing Element Update, and does not wish to approve the Housing Element
Update without such comments. The City has removed the Housing Element Update from the Project (and
associated IS/ND). The changes to the IS/ND do not affect the overall conclusions of the environmental
document; the analysis of the Safety Element Update is wholly bounded by the analysis and findings in
the previously circulated Draft IS/ND. This errata has been prepared to clarify and modify the Project.
PURPOSE OF ERRATA
The CEQA Guidelines Section 15073.5 requires that a lead agency recirculate a negative declaration “when
the document must be substantially revised.” A “substantial revision” includes: (1) identification of a new,
avoidable significant effect requiring mitigation measures or project revisions, and/or (2) determination
that proposed mitigation measures or project revisions will not reduce potential effects to less than
significance and new measures and revisions must be required.
The CEQA Guidelines specify situations in which recirculation of a negative declaration is not required.
This includes, but is not limited to, situations in which “new information is added to the negative
declaration which merely clarifies, amplifies, or makes insignificant modifications to the negative
declaration.” This errata addresses technical changes on the IS/ND. None of the clarifications and
insignificant modifications are considered “substantial revisions” because they do not show that the
Project has a new, avoidable significant effect and the City has determined that Project revisions are not
required to reduce potential effects to less than significant. None of the clarifications and modifications
substantially modify the analysis or conclusions of the IS/ND, but they instead merely remove discussion
of the Housing Element Update. As noted above, the clarified and modified Project would continue to
result in no impacts without any need for mitigation. The overall findings and analysis do not change.
Recirculation of the negative declaration is therefore not required in accordance with CEQA Guidelines
Section 15073.5.
Changes to the text are noted with underline (for added text) or strikeout type (for deleted text). The full
modified Negative Declaration is provided below.

CHAPTER 2.0 – PROJECT DESCRIPTION AND SETTING
2.1 INTRODUCTION
The City of Rolling Hills (City) is a rural, equestrian residential community, consisting entirely of large lot
residential parcels of one acre or more. The community encompasses 2.99 square miles of land
(approximately 1,910 acres) on the Palos Verdes Peninsula in the County of Los Angeles (Figure 2.2-1:
Project Location). The City’s General Plan was drafted and adopted in 1990. The City is proposing updates
to both the Housing Element and Safety Element of the General Plan, two one of the six elements. A
description of each of the updates is provided below.
2.1.1 Housing Element Update
The 2020 Census indicates a citywide population of 1,739 residents, making the City the fifth smallest of
the 88 cities in Los Angeles County. The City is proposing to adopt the Housing Element for the Sixth Cycle
planning period from 2021 to 2029. The proposed Housing Element Update (HEU) is attached hereto as
Appendix A. The Housing Element, which is part of the City’s General Plan, is a policy document designed
to provide the City a coordinated and comprehensive strategy for promoting the production of safe,
decent, and affordable housing within the community. California Government Code Section 65580 states
the following regarding the importance of creating housing elements:
The availability of housing is of vital statewide importance, and the early attainment of decent
housing and a suitable living environment for every Californian, including farmworkers, is a priority
of the highest order.
Per State law, the housing element has two main purposes:
1. To provide an assessment of both current and future housing needs and constraints in meeting
these needs; and
2. To provide a strategy that establishes housing goals, policies, and programs.
2.1.2 Safety Element Update
The Safety Element Update (SEU), (Appendix AB) provides the City’s goals, policies, and actions to
minimize the hazards to safety in and around the City. The SEU evaluates natural and human-caused safety
hazards that affect existing and future development and provides guidelines for protecting the community
from harm. The SEU describes existing and potential future conditions and sets policies for improved
public safety. The goal of the SEU is to reduce the risk of injury, death, property loss, and other hardships
to acceptable levels. A detailed description of the update is provided below.
2.2 SAFETY ELEMENT UPDATE
2.2.1 Background
Throughout its history as a city, the City has dealt with various natural hazards, including earthquakes,
wildfires, droughts, and land movement. Developments in high landslide areas have occurred, and the
City has been identified as being located in a Very High Fire Hazard Severity Zone (VHFHSZ). As a result,
430
City of Rolling Hills 2021-2029 Housing Element Update and Safety Element Update
Rolling Hills, Los Angeles County, California
Chambers Group, Inc.
21330
3
the City has amended its building and safety codes to include special requirements such as fire-rated
materials for new construction and a requirement for geotechnical studies in active fault zones.
2.2.2 Safety Element Overview
The City’s SEU addresses hazards of concern relevant to the City and provides goals, policies, and
implementation measures to minimize these hazards. Figures 2 through 6 of the SEU show exact locations
of these hazards, which are described in the following paragraphs.
Landslide Hazards
Much of the existing development in the City is located on hilly terrain and has a greater potential to
experience landslide hazards. Many of the canyons in the City exhibit steep slopes with little vegetation
coverage, leaving them susceptible to slope failure.
Seismic Hazards
The City is in a seismically active region of southern California. The last major earthquake in the Los
Angeles area was the 5.1 magnitude La Habra earthquake in 2014. The City is within 50 miles of the
Whittier fault, Newport-Inglewood fault, Palos Verdes fault, Malibu Coast fault, Cabrillo fault, Santa
Monica fault, and Redondo Canyon fault. Analysis of seismic data from the region indicates that the
Whittier and Newport-Inglewood faults may generate a maximum credible earthquake of magnitude 7.2
and 7.4, respectively. The earthquake shaking potential for the City is moderate. A number of seismically
active faults are present in the City and region; however, none are active faults with the potential for
ground rupture, defined by the Alquist-Priolo Earthquake Fault Zoning Act and delineated by California
Geological Survey. The City has a low potential for liquefaction, as the subsurface soils generally lack
saturated alluvial deposits and thick, granular soils.
Flooding
The City is not in any immediate risk from flooding caused by overflowing water bodies or heavy rains.
However, runoff and minor flooding pose a risk if drainage systems fail along canyon bottoms, where
natural drainage leads. Due to dam locations and the topography of the area, the inundation areas do not
enter or affect any portion of the City.
Wildland and Urban Fires
The entire City is designated a Very High Fire Hazard Severity Zone (VHFHSZ) by the California Department
of Forestry and Fire Protection (CAL FIRE 2011). The terrain in the City is composed of several large and
steep canyons that limit and challenge vegetation management and present conditions where a fire can
quickly travels up and downslope to nearby homes. Due to the rural nature and large residential lots,
many homes are surrounded by more substantial vegetation and dense brush than in more suburban
settings.

Hazardous Materials
According to the Department of Substances Control (DTSC 2021), no hazardous waste sites or facilities are
present in the City. The City and surrounding area do not contain heavy industrial uses that would create
a hazardous material risk in the event of a spill, release, or natural disaster.
2.2.3 Goals and Policies
Similar to the HEU, The SEU is a policy document; no actual development or rezoning of parcels is included
as part of the approval. In addition to goals and policies, the SEU includes implementation measures for
action items for the City. The goals, policies, and implementation for hazard mitigation, community
communication, and climate change adaptation and resilience are listed at the end of the SEU.

2.3 HOUSING ELEMENT UPDATE
2.3.1 Background
The City’s Housing Element serves as an integrated part of the General Plan and is subject to detailed
statutory requirements, including a requirement to be updated every eight years and mandatory review
by the California Department of Housing and Community Development (HCD). This action includes the
adoption of the HEU, which is a policy document; no actual development or rezoning of parcels is included
as part of the HEU. The proposed HEU is an eight-year plan for the 2021-2029 period.
Pursuant to Government Code Section 65583, a housing element is required to consist of an identification
and analysis of existing and projected housing needs and a statement of goals, policies, quantified
objectives, financial resources, and scheduled programs for the preservation, improvement, and
development of housing. Specifically, a housing element is required to contain the following:
An assessment of housing needs and an inventory of resources and constraints relevant to
meeting those needs (Government Code Section 65583[a])
A statement of the community’s goals, quantified objectives, and policies relative to the
maintenance, preservation, improvement, and development of housing (Government Code
Section 65583[a])
A program that sets forth a schedule of actions during the planning period, each with a timeline
for implementation of the policies and to achieve the goals and objectives of the housing element
(Government Code Section 65583[c])
Southern California Association of Governments (SCAG) began the Regional Housing Needs Allocation
(RHNA) process for the Sixth Cycle in Fall 2019, exploring different methodologies for allocating the
regional need to individual cities and counties. As other cities began work on their Sixth Cycle Elements,
the City was required to first amend its Fifth Cycle Element to accommodate both the current (Fifth) cycle
and the prior (Fourth) cycle RHNA allocations due to its noncompliant status. The combined RHNA for the
two cycles was 28 units. Accommodating this need meant that City was also required to amend its General
Plan and zoning to create additional housing capacity.
The Fifth Cycle Housing Element was adopted June 14, 2021. The Fifth Cycle Housing Element was
submitted to HCD and found to be in compliance on July 7, 2021. As a result of the compliance
determination, the City does not have to carry over its prior allocation and may plan only for the 45 units
identified in the Sixth Cycle RHNA.
2.3.2 Housing Element Overview
The City’s HEU consists of the following major components:
A review of the prior housing element and goals that were accomplished (Section 2, Evaluation of
Prior Housing Element)
434
City of Rolling Hills 2021-2029 Housing Element Update and Safety Element Update
Rolling Hills, Los Angeles County, California
Chambers Group, Inc.
21330

An assessment of housing needs in the City including profile and analysis of the City’s
demographics, housing characteristics, and existing and future housing needs (Section 3, Housing
Needs Assessment)
An assessment of resources available to meet the City’s objectives regarding housing production
and preservation. Resources include land available for new construction and redevelopment, as
well as financial and administrative resources available (Section 4, Housing Sites)
A review of the constraints to housing production and preservation. Constraints include potential
market, governmental policy, and environmental limitations to meeting the City’s identified
housing needs (Section 5, Constraints to Housing Production)
A statement of the housing plan to address the City’s identified housing needs, including housing
goals, policies, and programs (Section 6, Housing Goals, Policies, Objectives, and Programs)
2.3.3 Regional Housing Needs Allocation (RHNA)
State housing element law requires housing elements to be updated regularly to reflect a community’s
changing housing needs, including preparation of a RHNA plan [Government Code Section 65584(a)]. A
critical measure of compliance is the ability of a jurisdiction to accommodate its share of the regional
housing needs based on a RHNA prepared by HCD for each Council of Governments in the state that
identifies projected housing units needed for all economic segments based on Department of Finance
population estimates. The SCAG is responsible for allocating this total to each of the six counties and 191
cities in the SCAG area. This process is known as the RHNA and occurs every eight years.
SCAG calculates each city and county’s “fair share” of the regional need using a computer model that
weighs factors such as existing population and employment, growth potential, proximity to transit, and
social equity. For each jurisdiction, SCAG distributes the RHNA among four different income groups. This
ensures that each city or county is planning for housing that meet the needs of all economic segments of
the community, including lower income households.
For the City, the RHNA for 2021-2029 is 45 units (SCAG 2020). This includes 20 very low income units, 9
low income units, 11 moderate income units, and 5 above moderate income units. The 2021-2029 Housing
Element demonstrates that the City has the capacity to accommodate this assignment.
2.3.4 Summary of Ability to Meet RHNA
As shown in Table 2.3-1 below, the combination of recently approved housing units (expected to be
occupied in 2022), future affordable units on the Rancho Del Mar site 1, and new accessory dwelling units
(ADUs) can accommodate the RHNA allocation in all income categories. The table illustrates a surplus
capacity of seven lower income units based on projected ADU production over the planning period.
1 In March 2021, the City adopted an Affordable Housing Overlay Zone on the 31-acre Palos Verdes Peninsula
Unified School District (PVPUSD) property located at 38 Crest Road (Rancho Del Mar site). Although the site is
technically non-vacant, roughly three-quarters of the property (23 acres) is open space. The remaining areas are
underutilized and could be repurposed. Consistent with the General Plan and Zoning amendments completed in
2021, the site is viable for 16 units of low/very low income housing.

2.3.5 2021-2029 Goals and Policies
As previously mentioned, based on the City’s ability to meet RHNA allocation as described above, the HEU
is a policy document; no actual development nor rezoning of parcels is included as part of the approval.
The housing goals, policies, objectives, and programs which can be found in Chapter 6 of the HEU reflect
the City’s continued commitment to actively support residential development and plan for the City’s fair
share of regional housing needs.

CHAPTER 3.0 – ENVIRONMENTAL DETERMINATION
3.1 ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED:
The environmental factors checked below would potentially be affected by this project, involving at least
one impact that is a “Potentially Significant Impact," as indicated by the checklists on the following pages.
For each of the potentially affected factors, mitigation measures are recommended that would reduce the
impacts to less than significant levels.
Aesthetics Agriculture and Forestry Resources Air Quality
Biological Resources Cultural Resources Energy
Geology /Soils Greenhouse Gas Emissions Hazards & Hazardous Materials
Hydrology /Water Quality Land Use / Planning Mineral Resources
Noise Population / Housing Public Services
Recreation Transportation Tribal Cultural Resources
Utilities /Service Systems Wildfire Mandatory Findings of Significance
3.2 DETERMINATION
On the basis of this initial evaluation:
1. I find that the project could not have a significant effect on the environment, and a
NEGATIVE DECLARATION will be prepared.
2. I find that although the proposed project could have a significant effect on the
environment, there will not be a significant effect in this case because revisions in the
project have been made by or agreed to by the project proponent. A MITIGATED
NEGATIVE DECLARATION will be prepared.
3. I find the proposed project may have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
4. I find that the proposed project may have a “potentially significant impact” or
“potentially significant unless mitigated impact” on the environment, but at least one
effect (1) has been adequately analyzed in an earlier document pursuant to applicable
legal standards, and (2) has been addressed by mitigation measures based on the earlier
analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is
required, but it must analyze only the effects that remain to be addressed.
5. I find that although the proposed project could have a significant effect on the
environment, because all potentially significant effects (a) have been analyzed
adequately in an earlier EIR or Negative Declaration pursuant to applicable standards,
and (b) have been avoided or mitigated pursuant to that earlier EIR or Negative
Declaration, including revisions or mitigation measures that are imposed upon the
proposed project, nothing further is required.

CHAPTER 4.0 – EVALUATION OF ENVIRONMENTAL IMPACTS
1. A brief explanation is required for all answers except “No Impact” answers that are adequately
supported by the information sources a lead agency cites. A “No Impact” answer is adequately
supported if the referenced information sources show that the impact simply does not apply to
projects like the one involved (e.g., the project falls outside a fault rupture zone). A “No Impact”
answer should be explained where it is based on project-specific factors as well as general standards
(e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific
screening analysis).
2. All answers must take account of the whole action involved, including offsite as well as onsite,
cumulative as well as project-level, indirect as well as direct, and construction as well as operational
impacts.
3. Once the lead agency has determined that a particular physical impact may occur, then the checklist
answers must indicate whether the impact is potentially significant, less than significant with
mitigation, or less than significant. “Potentially Significant Impact” is appropriate if substantial
evidence exists that an effect may be significant. If one or more “Potentially Significant Impact” entries
are marked when the determination is made, an EIR is required.
4. “Negative Declaration: Less Than Significant With Mitigation Incorporated” applies where the
incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a
“Less Than Significant Impact.” The lead agency must describe the mitigation measures and briefly
explain how they reduce the effect to a less than significant level (mitigation measures from earlier
analyses may be cross-referenced).
5. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other California
Environmental Quality Act (CEQA) process, an effect has been adequately analyzed in an earlier
Environmental Impact Report (EIR) or negative declaration. Section 15063(c)(3)(D). In this case, a brief
discussion should identify the following:
a. Earlier Analysis Used. Identify and state where they are available for review.
b. Impacts Adequately Addressed. Identify which effects from the above checklist were within the
scope of and adequately analyzed in an earlier document pursuant to applicable legal standards,
and state whether such effects were addressed by mitigation measures based on the earlier
analysis.
c. Mitigation Measures. For effects that are “Less than Significant with Mitigation Measures
Incorporated,” describe the mitigation measures which were incorporated or refined from the
earlier document and the extent to which they address site-specific conditions for the project.
6. Lead agencies are encouraged to incorporate into the checklist references to information sources for
potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or
outside document should, where appropriate, include a reference to the page or pages where the
statement is substantiated.

would the project conflict with applicable zoning and
other regulations governing scenic quality?
(d) Create a new source of substantial light or glare
which would adversely affect day or nighttime views
in the area?
5.1.1 Impact Analysis
a) Would the project have a substantial adverse effect on a scenic vista?
b) Would the project substantially damage scenic resources, including, but not limited to, trees, rock
outcroppings, and historic buildings within a state scenic highway?
No Impact. The HEU and SEU are is aboth policy documents and does not include any changes to land
use designations, zoning, building heights and intensities, or residential densities. Further, the
Housing Element and Safety Element includes policies intended to continue to make the City a safe
and desirable place to work and live. All future development in the City would require project-specific
environmental evaluation in order to determine any potential impacts to scenic vistas. Additionally,
no officially designated State scenic highway is located in the City (Caltrans 2021). Potential aesthetic-
related impacts are unique to a project’s location and cannot be meaningfully determined until a
project site has been defined. Any future development would be subject to the City’s zoning
requirements, and any potentially significant impacts identified would be addressed through
mitigation measures specific to the impact. The Project would result in no impacts to scenic vistas or
scenic resources within a State scenic highway.
c) Would the project, in non-urbanized areas, substantially degrade the existing visual character or
quality of public views of the site and its surroundings? (Public views are those that are experienced
from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict
with applicable zoning and other regulations governing scenic quality?
No Impact. As previously mentioned, the Project would implement policies intended to continue to
make the City a safe and desirable place to work and live including efforts such as development and
landscaping policies, among others. The City’s current Zoning Code contains standards intended to
preserve the natural beauty of the City and to maintain visual orderliness, including provisions related
440
City of Rolling Hills 2021-2029 Housing Element Update and Safety Element Update
Rolling Hills, Los Angeles County, California
Chambers Group, Inc.
21330
2
to building standards (height, setbacks, intensities), screening of utilities in development, and outdoor
improvements. All future development in the City would be required to comply with the provisions of
the City’s Zoning Code and undergo project-specific environmental evaluation in order to determine
any potential impacts. The Project would result in no impacts to the visual character or quality of
public views or conflict with applicable zoning and other regulations governing scenic quality.
d) Create a new source of substantial light or glare which would adversely affect day or nighttime views
in the area?
No Impact. Sources of light present throughout the City include residential uses of both interior and
exterior lighting and vehicular traffic, while sources of glare include highly finished building materials
such as glass, and roadway traffic. The Project consists of two a policy documents and would not
directly enable construction or development. Nevertheless, all future residential development
enabled by the City’s General Plan is anticipated to introduce light and glare sources typical of
development; and all future development in the City would be subject to the City’s zoning
requirements. The City’s current Zoning Code contains lighting requirements intended to maintain
public health, safety, and welfare from noxious or offensive illumination, glare, or similar effects. All
future development in the City would be required to comply with the provisions of the City’s Zoning
Code and undergo project-specific environmental evaluation in order to determine any potential
impacts. The Project would result in no impact to the creation of light or glare that would adversely
affect views.

to use in assessing impacts on agriculture and
farmland. In determining whether impacts to
forest resources, including timberland, are
significant environmental effects, lead agencies
may refer to information compiled by the
California Department of Forestry and Fire
Protection regarding the state’s inventory of forest
land, including the Forest and Range Assessment
Project and the Forest Legacy Assessment project;
and forest carbon measurement methodology
provided in Forest Protocols adopted by the

5.2.1 Impact Analysis
a) Would the project convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance
(Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring
Program of the California Resources Agency, to non-agricultural use?
b) Would the project conflict with existing zoning for agricultural use, or a Williamson Act contract?
c) Would the project conflict with existing zoning for, or cause rezoning of, forest land (as defined in
Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section
4526), or timberland zoned Timberland Production (as defined by Government Code section
51104(g))?
d) Would the project result in the loss of forest land or conversion of forest land to non-forest use?
e) Would the project involve other changes in the existing environment which, due to their location or
nature, could result in conversion of Farmland, to non-agricultural use or the conversion of forest land
to non-forest use?
No Impact. The City does not contain any Prime Farmland, Unique Farmland, or Farmland of
Statewide Importance (DOC 2021a). Additionally, no land within the City is under a Williamson Act
contract (DOC 2017). The Project involves updates to the City’s Housing Element and Safety Element,
with no proposed changes to land use designations or zoning of parcels within the City. The City is a
residential community, and no provisions contained in the Housing Element Update or the Safety
Element Update would convert Prime Farmland or any farmland of unique or Statewide importance.
Further, no development is proposed on forestland or timber property zoned Timberland Production.
Any future development proposals would not conflict with an existing Williamson Act contract; that
would result in the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide
Importance to nonagricultural use or result in conversion or loss of forest land. Any future
development on properties zoned agricultural would be analyzed in a future site-specific
environmental document. Therefore, no impacts to agricultural or forestry resources would occur.

any criteria pollutant for which the project region is
non-attainment under an applicable federal or state
ambient air quality standard?
(c) Expose sensitive receptors to substantial pollutant
concentrations?
(d) Result in other emissions (such as those leading to
odors) adversely affecting a substantial number of
people?
5.3.1 Impact Analysis
a) Would the project conflict with or obstruct implementation of the applicable air quality plan?
b) Would the project result in a cumulatively considerable net increase of any criteria pollutant for which
the project region is non-attainment under an applicable federal or state ambient air quality standard?
No Impact. The City is located within the South Coast Air Basin, which is currently designated
nonattainment for ozone and fine particulate matter less than 2.5 microns in diameter (PM2.5)
(SCAQMD 1999). The South Coast Air Quality Management District (SCAQMD) prepared an air quality
management plan (AQMP) for both pollutants in 2016 and is currently working on the 2022 AQMP
(SCAQMD 2021). The Project would not directly result in construction or development activity, nor
would it enable development beyond that which is currently provided for in the City’s General Plan.
The number of residential units that could be developed under the HEU is consistent with the City’s
current General Plan and zoning designations. Potential air quality-related impacts are location-
specific and cannot be assessed in a meaningful way until the location of a project site is known. At
such time that a development proposal is considered, that project will be subject to adopted
development air quality standards; and any impacts identified with the development project will be
addressed through mitigation measures specific to the impact. Short-term air quality impacts resulting
from construction activities, such as dust generated by clearing and grading activities, exhaust
emissions from gas- and diesel-powered construction equipment, and vehicular emissions associated
with the commuting of construction workers, will be subject to SCAQMD air quality management
plans identified above and all other relevant SCAQMD rules and regulations.
Thus, the Project would result in no impacts related to implementation of any applicable air quality
plan, nor would it result in a cumulatively considerable net increase of any criteria pollutant for which
the Project region is nonattainment under an applicable federal or State ambient air quality standard.
c) Would the project expose sensitive receptors to substantial pollutant concentrations?
No Impact. As mentioned, the HEU and SEU are bothis a policy documents and does not include any
changes to land use designations or zoning. Moreover, the Project does not directly enable
construction or development activities. Potential air quality-related impacts are location-specific and
cannot be assessed in a meaningful way until the location of a project site is known. The City’s General
Plan and Municipal Code contain policies and measures related to maintaining air quality in residential
neighborhoods, including protecting neighborhoods from air pollution-generating activities through
site-specific environmental review and appropriate development buffers. At the time that a
development proposal is considered, that project will be subject to the development review process,
and any potentially significant impacts identified would be addressed through mitigation measures
443

specific to the impact. Thus, the Project would result in no impacts related to the exposure of sensitive
receptors to substantial pollutant concentrations.
d) Would the project result in other emissions (such as those leading to odors) adversely affecting a
substantial number of people?
No Impact. Impacts would be considered potentially significant if the Project were to result in the
creation of objectionable odors with the potential to affect substantial numbers of people, or if
construction or operation of the Project would result in the creation of nuisance odors that would be
noxious to a substantial number of people. The City’s General Plan and Municipal Code contain
policies and measures related to maintaining air quality in residential neighborhoods, including
protecting neighborhoods from odor-generating activities through site-specific environmental review
and appropriate development buffers.
Residential development, such as that described in the HEU, is not a land use typically associated with
odor complaints or noxious emissions. Moreover, tThe SEU contains policies to prevent health threats
due to air quality impacts such as those associated with wildfire. The Project would not directly enable
construction or development activities upon implementation. At the time that a development
proposal is considered, that project will be subject to the development review process; and any
potentially significant impacts identified would be addressed through mitigation measures specific to
the impact. The Project would therefore not result in impacts related to emissions adversely affecting
a substantial number of people.

5.4.1 Impact Analysis
a) Would the project have a substantial adverse effect, either directly or through habitat modification,
on any species identified as candidate, sensitive or special status species in local or regional plans,
policies or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife
Service?
No Impact. The City’s environs have the capacity to house a range of plant and wildlife species,
including State and federally listed species. To protect candidate, sensitive, or special status species
all future development in the City would require project-specific environmental evaluation in order
to determine any potential impacts. Potential impacts related to biological resources are unique to a
project’s location and cannot be meaningfully determined until a project site has been defined. Any
future development would be subject to federal, State, regional, and local regulatory requirements
related to biological resources.
Further, the HEU and SEU includes policies intended to lessen impacts to biological resources,
including policies to minimize housing construction in environmentally sensitive areas and policies for
climate change adaptation and resiliency. Additionally, future projects would be evaluated by the City
for their compliance with goals, policies, and measures contained in the City’s General Plan intended
to mitigate potential impacts to natural and biological resources, including those contained in the
Open Space and Conservation Element. Any potentially significant environmental impacts identified
from future development would be addressed through project specific mitigation measures identified
at the time a specific development project is considered by the City. Therefore, the Project would
have no impacts on any candidate, sensitive, or special status species.
b) Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies or regulations, or by the California Department
of Fish and Wildlife or U.S. Fish and Wildlife Service?
c) Would the project have a substantial adverse effect on state or federally protected wetlands (including
but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological
interruption, or other means?
No Impact. A substantial amount of land in the City is constrained from development due to steep
hillsides and canyons, many of which contain intermittently flooded riparian and wetland habitat
(USFWS 2021). However, the HEU and SEU are bothis a policy documents and would not directly
enable construction or development activity. Potential impacts related to sensitive natural
communities, such as riparian or wetland habitats, are unique to a project’s location and cannot be

meaningfully determined until a project site has been defined. Thus, all future development in the
City would require project-specific environmental evaluation. Any potentially significant
environmental impacts identified from future development would be addressed through project-
specific mitigation measures identified at the time a specific development project is considered by
the City. Therefore, the Project would have no impacts on any riparian habitat, other sensitive natural
communities, or on State or federally protected wetlands.
d) Would the project Interfere substantially with the movement of any native resident or migratory fish
or wildlife species or with established native resident or migratory wildlife corridors, or impede the use
of native wildlife nursery sites?
No Impact. The City is a heavily landscaped residential community interspersed with undeveloped
steep hillsides and canyons (City 1990). Within these undeveloped areas, the potential exists for
nesting birds and other species to occur. Nonetheless, the HEU and SEU are is a policy documents
consistent with the City’s General Plan and does not propose any land use or zoning changes. Further,
future development will require site-specific environmental analysis. Potential environmental impacts
identified from future development would be addressed through project-specific mitigation measures
identified at the time a specific development project is considered by the City. Therefore, the Project
would have no impacts to the movement of native resident or migratory fish or wildlife species,
corridors, or nursery sites.
e) Would the project conflict with any local policies or ordinances protecting biological resources, such
as a tree preservation policy or ordinance?
f) Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural
Conservancy Conservation Plan, or other approved local, regional, or state habitat conservation plan?
No Impact. The County of Los Angeles’s Significant Ecological Area (SEA) Program was originally
established as a part of the 1980 County General Plan, to help conserve the genetic and physical
diversity in the County. The SEA Ordinance, which codified the SEA Program, establishes the
permitting, design standards and review process for development within SEAs. The City contains
portions of the Palos Verdes Peninsula and Coastline SEA; however, only areas within unincorporated
Los Angeles County are subject to this ordinance. Further, policies and programs of the HEU promote
infill housing including ADUs. No development would occur pursuant to the SEU. Any development
that occurs pursuant to HEU or SEU policies will occur in already disturbed areas of the community
and will be reviewed and processed in accordance with City planning policies. Therefore, the Project
would not conflict with any local policies, ordinances, or plans protecting biological resources; and no
impacts would occur.

pursuant to §15064.5?
b) Would the project cause a substantial adverse change in the significance of an archaeological resource
pursuant to §15064.5?
c) Would the project disturb any human remains, including those interred outside of formal cemeteries?
No Impact. The Project involves adoption of two a policy documents, the HEU and SEU, which does
not directly propose any ground disturbance. Potential impacts related to cultural resources are
unique to a project’s location and cannot be meaningfully determined until a project site has been
defined. Thus, all future development in the City would require project-specific environmental
evaluation in order to determine any potential impacts. Future development would be subject to
federal, State, and local regulatory requirements related to the discovery and proper handling of
cultural and historic resources, including Public Resource Code (PRC) Section 211083.2, which requires
avoidance and other measures in the event of discovery. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Therefore,
no impacts to cultural resources would occur with implementation of the Project.

a) Would the project result in potentially significant environmental impact due to wasteful, inefficient, or
unnecessary consumption of energy resources, during project construction or operation?
No Impact. The HEU and SEU are is consistent with the City’s General Plan and contain policies to
conserve energy resources. However, potential impacts related to energy resources are unique to a
project and cannot be meaningfully determined until a project has been defined. The HEU also seeks
to conserve energy through public education on the reduction of residential energy use. Any future
development would also be subject to individual review for compliance with federal, State, and local

regulatory requirements related to energy efficiency. Future development projects would incorporate
site-specific infrastructure improvements, as necessary, and would be reviewed by relevant energy
providers to identify necessary energy facility and service connections. Additionally, future projects
would be evaluated by the City for their compliance with goals, policies, and measures contained in
the City’s General Plan intended to mitigate potential impacts to energy resources. Any potentially
significant environmental impacts identified from future development would be addressed through
project-specific mitigation measures identified at the time a specific development project is
considered by the City. Thus, no impacts would occur.
b) Would the project conflict with or obstruct a state or local plan for renewable energy or energy
efficiency?
No Impact. Any future development in the City would be subject to federal, State, and local regulatory
requirements related to energy efficiency. Additionally, goals, policies, and programs related to
reducing greenhouse gas (GHG) emissions (as discussed in Section 5.8: Greenhouse Gas Emissions)
are closely related to reducing energy consumption through the use of alternative forms of energy or
sustainable design features.
Future projects would be evaluated by the City for their compliance with goals, policies, and measures
contained in the City’s General Plan intended to mitigate potential impacts to energy resources. Any
potentially significant environmental impacts identified from future development would be

risk of loss, injury, or death involving seismic-related ground failure, including liquefaction?
iv) Would the project directly or indirectly cause potential substantial adverse effects, including the
risk of loss, injury, or death involving landslides?
No Impact. Rolling Hills is in a seismically active region of southern California, with the Whittier fault,
Newport-Inglewood fault, Palos Verdes fault, Malibu Coast fault, Cabrillo fault, Santa Monica fault,
and Redondo Canyon fault all within 50 miles of the City. The closest active fault to the City is the
Palos Verdes Fault, located within the City boundaries. While there are a number of seismically active
faults in the City and region, there are no active faults with the potential for ground rupture, defined
by the Alquist-Priolo Earthquake Fault Zoning Act. The closest Alquist-Priolo Fault Zone is the
Newport-Inglewood Fault approximately nine miles northeast of the City (City 1990).
Regarding other geologic hazards, much of the existing development in Rolling Hills is located on hilly
terrain highly susceptible to landslide risks. However, the potential for liquefaction, lateral spreading,
and seismically induced dynamic settlement is low (City 1990).
The SEU addresses the protection of the existing and future population and development from both
natural and man-made hazards through a number of goals, policies, implementation programs,
principles, and standards. Among these is Goal 1 of the SEU, which aims for “minimization of loss of
life, injury, and property damage resulting from geologic hazards”. Additionally, the Project includes
implementation of two a policy documents and no development is proposed at this time. All future
development in the City would require project-specific environmental evaluation in order to
determine that any potential impacts are less than significant. Any future development would be
subject to federal, State, and local regulatory requirements related to building design and

construction. Any potentially significant impacts identified would be addressed through mitigation
measures specific to the impact. Therefore, the Project would result in no impacts related to the direct
or indirect cause of potential substantial adverse effects, including the risk of loss, injury, or death,
involving rupture of a known earthquake fault, strong seismic ground shaking, and seismic-related
ground failure, including liquefaction or landslides.
b) Would the project result in substantial soil erosion or the loss of topsoil?
No Impact. The Project consists of two a policy documents and would not directly enable construction
or development activities. Any future development in the City would be subject to State, regional, and
local requirements related to the prevention of erosion of onsite soils, as well as discharge of other
construction-related pollutants, through the preparation and implementation of a Stormwater
Pollution Prevention Plan (SWPPP) and Best Management Practices (BMPs). Additionally, future
projects would be evaluated by the City for their compliance with goals, policies, and measures
contained in the SEU intended to protect lives and property. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Therefore,
the Project would have no impacts related to soil erosion or the loss of topsoil.
c) Would the project be located on a geologic unit or soil that is unstable, or that would become unstable
as a result of the project, and potentially result in on- or off-site landslide, lateral spreading,
subsidence, liquefaction or collapse?
No Impact. As previously discussed, much of the existing development in Rolling Hills is located on
hilly terrain; and many of the City’s canyons exhibit steep slopes with little vegetation coverage. These
areas are highly susceptible to landslide risks. However, the City generally lacks the thick, loose, sandy
soils which lead to liquefaction and ground failure hazards. Thus, the potential for liquefaction, lateral
spreading, and seismically induced dynamic settlement is low (City 1990).
The HEU and SEU are is a policy documents; thus, the Project does not directly propose physical
changes in the environment and does not, in and of itself, enable future development. To account for
any potential instability, all future development projects would be evaluated on a site-specific basis
and would be subject to federal, State, and local regulatory requirements related to building design
and construction. Any potentially significant environmental impacts identified from future
development would be addressed through project-specific mitigation measures identified at the time
a specific development project is considered by the City. Thus, the Project would have no impacts
related to location on a geologic unit or soil that is unstable or that would become unstable as a result
of the Project and potentially result in on or offsite landslide, lateral spreading, subsidence,
liquefaction, or collapse.
d) Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code
(1994), creating substantial direct or indirect risks to life or property?
No Impact. Expansive soils are characterized as fine-grained, such as silts and clays or soils with
variable amounts of expansive clay minerals that can change in volume due to changes in water
content. According to the General Plan, soil types within the City consist predominantly of fertile clays
with some loams and shales (City 1990). Nevertheless, the HEU and SEU are is a policy documents;
thus, the Project does not directly propose physical changes in the environment and does not, in and
450

of itself, enable future development. Future development would be evaluated in separate, site-
specific CEQA documents and would be subject to federal, State, and local regulatory requirements
related to building design and construction. Potential environmental impacts from future
development would be addressed through project-specific mitigation measures identified at the time
a development project is considered by the City.
e) Would the project have soils incapable of adequately supporting the use of septic tanks or alternative
waste water disposal systems where sewers are not available for the disposal of waste water?
No Impact. With the exception of a Palos Verdes Unified School District site and 13 residences that
have individually or collectively (through the creation of a small sewer district) connected to an
adjacent jurisdiction’s sewer systems, no sanitary sewer system exists in Rolling Hills. Residences are
served by individual septic tanks and seepage pits. These systems are designed to serve single-family
residences and are not conducive to multi-family housing; particularly given the geologic, slope, and
soil constraints in Rolling Hills. However, the HEU and SEU are is a policy documents consistent with
the City’s General Plan and does not propose any land use or zoning changes. Moreover, all future
development would be evaluated on a site-specific basis and subject to federal, State, and local
regulatory requirements related to building design and construction. Any potentially significant
environmental impacts identified from future development would be addressed through project-
specific mitigation measures identified at the time a specific development project is considered by
the City. The Project would have no impacts related to soils incapable of adequately supporting the
use of septic tanks or alternative wastewater disposal systems.
f) Would the project directly or indirectly destroy a unique paleontological resource or site or unique
geological feature?
No Impact. All future development in the City would require project-specific environmental
evaluation in order to determine that any potential impacts are less than significant. Potential impacts
related to paleontological and geologic resources are unique to a project and site and cannot be
meaningfully determined until a project has been defined. In the event that paleontological resources
are discovered during future development projects, applicants will be required to comply with
regulatory standards enumerated under in PRC Section 5097.574, which sets the protocol for proper
handling. Any potentially significant environmental impacts from future development would be
analyzed in a separate CEQA document and addressed through project-specific mitigation measures
identified at the time a development project is considered by the City. Therefore, the Project would
have no impacts related to the direct or indirect destruction of a unique paleontological resource or
site or unique geologic feature.

5.9.1 Impact Analysis
a) Would the project create a significant hazard to the public or the environment through the routine
transport, use, or disposal of hazardous materials?
No Impact. The HEU and SEU are is a policy documents consistent with the City’s General Plan. The
Project does not directly propose physical changes in the environment and does not, in and of itself,
enable future development. Moreover, the SEU addresses the protection of the existing and future
population and development from both natural and man-made hazards through a number of goals,
policies, implementation programs, principles, and standards. Among these are measures to mitigate
the risk from hazardous materials.
Construction activities associated with future individual development projects would likely involve the
temporary transportation, management, and use of oils, fuels and other potentially flammable
substances, such as paints, solvents, and cleaners. Hazardous materials that may be present during
operation of future individual projects are usually associated with landscaping and building
maintenance. Nevertheless, any future development in the City would be subject to federal, State,
and local regulatory requirements related to the transport, use, or disposal of hazardous materials.
All potential environmental impacts resulting from future development would be analyzed in a
separate environmental document and addressed through project-specific mitigation measures
identified at the time a specific development project is considered by the City.
b) Would the project create a significant hazard to the public or the environment through reasonably
foreseeable upset and accident conditions involving the release of hazardous materials into the
environment?
No Impact. Residential uses enabled by the City’s HEU are generally not characterized as substantial
generators of hazardous materials, nor are they anticipated to result in upset or accident conditions
involving the release thereof. Further, Tthe SEU addresses the protection of the existing and future
population and development from both natural and man-made hazards, including hazardous
materials. Regardless, the Project involves two a policy documents and would not directly result in
physical changes in the environment. Any future development would be subject to all applicable
regulatory requirements concerning the proper handling, treatment, and disposal of hazardous
materials. Any potentially significant environmental impacts identified from future development
would be addressed through project-specific mitigation measures identified at the time a specific
development project is considered by the City.
c) Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials,
substances, or waste within one-quarter mile of an existing or proposed school?
No Impact. The City only has one school in its boundary: Rancho Del Mar High School located in the
western portion of the City. Potential hazardous material-related impacts are location-specific and
453

cannot be assessed in a meaningful way until the location of a project site is known. At such time that
a development proposal is considered, that project will be subject to the development review process;
and any potentially significant impacts would be addressed through mitigation measures specific to
the impact. Since the current Project involves two a policy documents and does not directly propose
physical changes in the environment, no impacts related to the emission or handling of hazardous or
acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed
school would occur.
d) Would the project be located on a site which is included on a list of hazardous materials sites compiled
pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to
the public or the environment?
No Impact. According to the Department of Toxic Substances Control (DTSC), no potential hazardous
waste sites are under evaluation in Rolling Hills (DTSC 2021; SWRCB 2021). The City and surrounding
area do not contain heavy industrial uses that would create a hazardous material risk in the event of
a spill, release, or natural disaster. Additionally, the City is not located near any major transit routes
involving transport of a substantial quantity of hazardous material through the City (City 1990).
The Project involves two a policy documents and does not directly propose physical changes in the
environment. Any future development would be subject to all applicable regulatory requirements
concerning the proper handling, treatment, and disposal of hazardous materials. Any potentially
significant environmental impacts identified from future development would be addressed through
project-specific mitigation measures identified at the time a specific development project is
considered by the City. The Project would result in no impacts related to location on a site which is
included on a list of hazardous materials sites compiled pursuant to Government Code Section
65962.5.
e) For a project located within an airport land use plan or, where such a plan has not been adopted,
within 2 miles of a public airport or public use airport, would the project result in a safety hazard or
excessive noise for people residing or working in the project area?
No Impact. The HEU and SEU is aare policy documents that analyzes housing and safety needs in the
City. The City is within 2 miles of the Torrance Airport, which is approximately 1.4 miles from the
northern boundary of the City. However, the City is not located within the airport or airfield safety
hazard zone (ALUC 2003). The Project proposes adoption of the SEU, which is a policy document that
would not result in direct development or construction. Any development that occurs pursuant to
Housing Element or Safety Element policies will be subject to State and local regulations regarding the
transport, use, and disposal of hazardous materials and to City planning, engineering, and building
requirements. No impacts relative to noise hazards are expected to occur as a result of the Project.
f) Would the project impair implementation of or physically interfere with an adopted emergency
response plan or emergency evacuation plan?
No Impact. The City’s Community Wildfire Protection Plan (CWPP) identifies the potential evacuation
routes listed below, which include options for rapid egress from areas within the City if threatened by
a wildfire.

The SEU addresses the protection of the existing and future population and development from both
natural and man-made hazards through a number of goals, policies, implementation programs,
principles, and standards. Among these are measures to provide and maintain an emergency response
system for the City. Moreover, future development in the City would be required to comply with the
provisions of the City’s General Plan and Hazard Mitigation Plan during construction and operation.
Any potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Thus, the Project would result in no impacts related to the
impairment of or physical interference with an adopted emergency response plan or emergency
evacuation plan.
g) Would the project expose people or structures, either directly or indirectly, to a significant risk of loss,
injury or death involving wildland fires?
No Impact. The entire City is designated as Very High Fire Hazard Severity Zone (VHFHSZ) by CAL FIRE
(2011). The SEU and HEU addresses the protection of the existing and future population and
development from both natural and man-made hazards through a number of goals, policies,
implementation programs, principles, and standards. Among these are measures to mitigate the risk
from the hazards of fire and ensure the protection of people and wildlife from hazardous materials in
the community.
Further, future development in the City would be required to comply with the provisions of the City’s
General Plan and CWPP during construction and operation. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Thus, the
Project would not expose people or structures to loss, injury, or death involving wildland fires; and no
impacts would result.

5.10.1 Impact Analysis
a) Would the project violate any water quality standards or waste discharge requirements, or otherwise
substantially degrade surface or ground water quality?
No Impact. The Project involves twoa policy documents which arethat is consistent with the City’s
General Plan and does not directly propose physical changes to the environment. Future development
in the City would be required to follow State, regional, and local regulations regarding onsite
stormwater retention, so that surface waters and the groundwater aquifer are not contaminated with
Project-related pollutants. To comply with federal National Pollutant Discharge Elimination System
(NPDES) requirements and maintain its Municipal Separate Storm Sewer System (MS4) permit, the
City is required to screen and monitor its runoff to avoid compromising downstream water quality
standards. It is also required to implement a number of programs, such as an Illicit Discharge
Elimination Program. The City requires BMPs for construction in order to avoid erosion, pollution,
sedimentation, and runoff that would degrade water quality. Any potentially significant
environmental impacts identified from future development would be addressed through project-
specific mitigation measures identified at the time a specific development project is considered by
the City. Thus, the Project would have no impact related to violation of any water quality standards
or waste discharge requirements or otherwise substantially degrade surface or groundwater quality.
b) Would the project substantially decrease groundwater supplies or interfere substantially with
groundwater recharge such that the project may impede sustainable groundwater management of
the basin?
No Impact. The City’s water infrastructure is owned, maintained, and operated by California Water
Service Palos Verdes District (District). According to the District’s 2020 Urban Water Management
Plan (UWMP), the current water supply for the customers of the District is purchased imported water
and groundwater is not being used as a source of supply (CalWater 2021). Further, all future
development in the City would require project-specific environmental evaluation in order to
determine any potentially significant impacts to groundwater and required project-specific mitigation

measures. Any future development would also be subject to all applicable State, regional, and local
regulatory requirements concerning the efficient use and conservation of water resources, including
measures identified in the City’s General Plan. Therefore, the Project would result in no impacts
related to groundwater supplies or groundwater recharge.
c) Would the project substantially alter the existing drainage pattern of the site or area, including
through the alteration of the course of a stream or river or through the addition of impervious surfaces,
in a manner which would:
i) result in substantial erosion or siltation on- or off-site;
ii) substantially increase the rate or amount of surface runoff in a manner which would result in
flooding on- or off-site;
iii) create or contribute runoff water which would exceed the capacity of existing or planned
stormwater drainage systems or provide substantial additional sources or polluted runoff; or
iv) impede or redirect flood flows?
No Impact. The Project involves two a policy documents which are is consistent with the City’s
General Plan and does not directly propose physical changes to the environment. The City’s SEU
also contains principles and standards intended to minimize risk from flooding or erosion.
Nonetheless, potential impacts related to drainage are unique to a project and cannot be
meaningfully determined until a project site has been defined. Future development in the City
would be required to follow State, regional, and local regulations regarding drainage, erosion, and
runoff. As mentioned, the City is required to screen and monitor its runoff to avoid compromising
downstream water quality standards to comply with federal NPDES requirements and maintain
its MS4 permit. The City also requires BMPs for construction in order to avoid erosion, pollution,
sedimentation, and runoff that would degrade water quality. Any potentially significant
environmental impacts identified from future development would be addressed through project-
specific mitigation measures identified at the time a specific development project is considered
by the City. Thus, the Project would have no impacts.
d) Would the project in flood hazard, tsunami, or seiche zones, risk release of pollutants due to project
inundation?
No Impact. According to Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map
(FIRM) panels 06037C2026G, 06037C2027G, and 06037C1940F, the City is not located in a flood hazard
area and currently has a less than 0.2 percent annual chance to be inundated by flood waters as a
result of a storm event (FEMA 2021). Additionally, the City is not located within a tsunami or seiche
zone (DOC 2021b; DWR 2021). Regardless, all future development in the City would require project-
specific environmental evaluation in order to determine any potential impacts. Future development
would be subject to all applicable federal, State, and local regulatory requirements concerning flood
hazards, including measures identified in the City’s General Plan intended to minimize impacts. Any
potentially significant environmental impacts identified from future development would be addressed
through project-specific mitigation measures identified at the time a specific development project is
considered by the City. Therefore, the Project would result in no impact related to risking release of
pollutants due to Project inundation in flood hazard, tsunami, or seiche zones.
e) Would the project conflict with or obstruct implementation of a water quality control plan or
sustainable groundwater management plan?
457

No Impact. The Project involves updating two a policy documents and does not propose any zoning
or land use changes, or authorize any physical development. Any future development that occurs
pursuant to the HEU or SEU in the City will be subject to State and local regulations regarding water
quality, run-off, and hydrology and to City planning, engineering and building requirements. The
Project would not conflict with or obstruct implementation of a water quality control plan or
sustainable groundwater management plan; thus, no impacts would occur.

5.11.1 Impact Analysis
a) Would the project physically divide an established community?
b) Would the project cause a significant environmental impact due to a conflict with any land use plan,
policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?
No Impact. The City has prepared its HEU and SEU in accordance with Section 65580 and Section
65302(g) of the Government Code, respectively. The updates has have also been prepared consistent
with the City General Plan and the community’s vision of its housing and safety needs and objectives.
Accordingly, the HEU examines the City’s housing needs as they exist today and projects future
housing needs based on RHNA allocation. No change to the land use plan or zoning map is proposed
as part of the HEU. The SEU identifies and offers goals, policies, and actions to minimize the City’s
hazards which pose a risk of injury, death, property loss, and other hardships. Any subsequent
discretionary actions or development that occur pursuant to HEU policies will be reviewed and
processed in accordance with City planning policies. The HEU and SEU hasve been prepared in full
compliance with the State law, and no potential adverse impacts relative to land use would occur.

b) Would the project result in the loss of availability of a locally-important mineral resource recovery site
delineated on a local general plan, specific plan or other land use plan?
No Impact. The City is not designated as having any known mineral resources. Although mineral
resources exist in the area, they are outside the City limits and outside the boundaries of the General
Plan (City 1990). Additionally, the Project proposes implementation of the HEU and SEU, which are is
a policy documents consistent with the General Plan. No land use or zoning changes are proposed,
and the Project would not result in direct physical changes to the environment. All future
development would require project-specific environmental evaluation in order to determine any
potentially significant impacts and would integrate project-specific mitigation measures if needed.
Therefore, the Project would have no impacts on the availability of any known resources or locally

5.14.1 Impact Analysis
a) Would the project induce substantial unplanned population growth in an area, either directly (for
example, by proposing new homes and businesses) or indirectly (for example, through extension of
roads or other infrastructure)?
b) Would the project displace substantial numbers of existing people or housing, necessitating the
construction of replacement housing elsewhere?
No Impact. As the regional planning agency for the Los Angeles region, SCAG is responsible for
preparing jurisdiction-level forecasts for each city and county in the region. The latest forecasts were
adopted in September 2020 and describe conditions in a base year (2016) and forecast year (2045).
SCAG forecasts indicate that City growth will be flat through 2045, with the latest published forecasts
showing 700 households in 2016 and 700 households in 2045. Population in the City over the
equivalent period is shown as increasing from 1,900 to 2,000, a growth rate of about 5 percent over
29 years (SCAG 2020).
The 2021-2029 RHNA allocation for the City is 45 units, including 20 very low income units, 9 low
income units, 11 moderate income units, and 5 above moderate income units. As previously shown in

Table 2.3-1, the combination of recently approved housing units (expected to be occupied in 2022),
future affordable units on the Rancho Del Mar site, and new ADUs, which have been made easier to
develop under a series of recently passed legislation, can accommodate the RHNA allocation in all
income categories. The table illustrates a surplus capacity of seven lower income units based on
projected ADU production over the planning period. Any subsequent development accomplished
pursuant to the HEU or SEU will be consistent with State and regional growth mandates. The Project
does not include any development that would increase population directly or indirectly and The
Project will not displace housing or people. but, conversely, is intended to promote affordability and
increase housing supply, which can support retention of households in all income categories. No
impacts relative to population or housing would occur as a result of the Project.

not authorize future development. All future development would require project-specific
environmental evaluation in order to determine any potential impacts to recreational facilities.
Further, future development would be required to adhere to State and local regulations as well as the
policies, principles, standards, and mitigation outlined in other sections of the General Plan.
Therefore, the Project would have no impact on existing recreational facilities.
b) Does the project include recreational facilities or require the construction or expansion of recreational
facilities which might have an adverse physical effect on the environment?
No Impact. The Project proposes adoption of the HEU and SEU, both of which are is a policy
documents that would not result in direct development or construction. Therefore, the Project would
not construct any recreational facilities or require the expansion of any recreational facilities. No
impacts would occur to or from recreational facilities.

a) Would the project conflict with a program, plan, ordinance or policy addressing the circulation system,
including transit, roadways, bicycle and pedestrian facilities?
b) Would the project Conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)?
c) Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves
or dangerous intersections) or incompatible uses (e.g. farm equipment)?
No Impact. Rolling Hills has no public roads or streets; thus the City's circulation infrastructure is not
conducive to uses generating high trip volumes (City 2014). Nonetheless, the HEU and SEU are is a
policy documents consistent with the General Plan. The updates does not include any changes to land
use designations, zoning, building heights and intensities, or residential densities. Any future
development would be required to adhere to all programs, ordinances, and policies that address
circulation, including those in the General Plan Circulation Element and the City’s Municipal Code. Any
potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Thus, no circulation-related impacts would result from the Project.
d) Would the project result in inadequate emergency access?
No Impact. Many streets in the community are “dead ends” without emergency vehicle access
alternatives in the event that ingress and egress is blocked (City 2014). However, the SEU addresses
the protection of the existing and future population and development from both natural and man-
made hazards through a number of goals, policies, implementation programs, principles, and
standards. To ensure adequate emergency access, future development in the City would be required
to undergo environmental analysis and comply with the provisions of the Municipal Code during
construction and operation. Any potentially significant environmental impacts identified from future
development would be addressed through project-specific mitigation measures identified at the time
a specific development project is considered by the City. Thus, the Project would result in no impacts
related to emergency access.

subdivision (c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance
of the resource to a California Native American tribe?
According to the California PRC Section 21084, a project may have a significant effect on the
environment if the project “may cause a substantial adverse change in the significance of an historical
resource.” Assembly Bill 52 (AB 52) specifies that a project with the potential for adverse effects on
tribal cultural resources may be considered a significant effect on the environment. Additionally,
Senate Bill 18 (SB 18) requires a government-to-government consultation process initiated by the local
governmental agency prior to adoption or amendment of a General or Specific Plan.
The City, as the Lead Agency pursuant to CEQA and as required by AB 52 and SB 18, has consulted
with the local Native American Tribes in the Project Area. Tribes that are located regionally include:
Gabrieleno Band of Mission Indians - Kizh Nation, Gabrieleno/Tongva San Gabriel Band of Mission

Indians, Gabrielino /Tongva Nation, Gabrielino Tongva Indians of California, Gabrielino-Tongva Tribe,
Santa Rosa Band of Cahuilla Indians, and Soboba Band of Luiseño Indians. Letters were sent to these
Tribes on December 13, 2021. Tribes were requested to respond to AB 52 by January 12, 2022, and
SB 18 by January 27, 2022.
As of the release of this document, the Gabrieleño Band of Mission Indians - Kizh Nation responded
with two separate letters on December 21, 2021 noting that they had no comments or concerns and
no additional information to provide regarding the HEU or SEU, but requesting consultation for any
and all future projects with ground disturbance as shown in Appendix BC: Tribal Consultation
Response. Additionally, the Gabrielino Tongva Indians of California responded noting that the City is
a highly culturally sensitive area and expressed interest in finding out more information regarding the
project, however, after review of the project, they submitted a follow up email stating that they have
no concerns, but requested notification on future projects.
The HEU and SEU are is a policy documents that would not result in direct development or
construction. As noted, to date, two Tribes responded during the consultation process and did not
have any comments or concerns. Similar to the Project, future projects would be required comply
with AB 52 and SB 18, which require consultation with any Tribes that request consultation. The
Project would not cause a substantial adverse change in the significance of a Tribal Cultural Resource
listed or eligible for listing in the California Register of Historical Resources or in the local register of
historical resources as defined in PRC Section 5020.1(k). Thus, no impacts to Tribal Cultural Resources
would occur.

5.19.1 Impact Analysis
a) Would the project require or result in the relocation or construction of new or expanded water,
wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications
facilities, the construction or expansion of which could cause significant environmental effects?
No Impact. The Project is for the adoption of the City’s HEU and SEU, which are is a policy documents
that would not result in direct development or construction. The HEU identifies approved housing
developments and the construction of ADUs within the City to meet RHNA allocation. According to
the HEU, the principal site improvements required upon development of a vacant property in the City
are the undergrounding of electrical lines to the structure, installation of a septic system, and
conformance to the City’s outdoor lighting standards.
All future development in the City would require project-specific environmental evaluation and would
be subject to all applicable State, regional, and local regulatory requirements concerning the
installation of utilities. Any potentially significant environmental impacts identified from future
development would be addressed through project-specific mitigation measures identified at the time
a specific development project is considered by the City. The HEU and SEU are is a policy documents
that would not result in direct development or construction. Therefore, the Project would have no
impacts regarding the construction or expansion of new or expanded water, wastewater treatment
or stormwater drainage, electric power, natural gas, or telecommunications facilities.
b) Would the project have sufficient water supplies available to serve the project and reasonably
foreseeable future development during normal dry and multiple dry years?
No Impact. According to the 2020 UWMP, the District’s only source of water supply is imported,
purchased water from the West Basin Municipal Water District (WBMWD) (CalWater 2021). The
WBMWD Draft 2020 UWMP states that it will be able to serve 100 percent of projected demands in
normal, single-dry and multiple-dry years. As such, the District expects that, under all hydrologic
conditions, purchased water supplies (in combination with the future recycled supplies) will fully serve
future potable demands (CalWater 2021).
Further, all future development in the City would require project-specific environmental evaluation
in order to determine any potential impacts to groundwater. Any future development would also be
subject to all applicable State, regional, and local regulatory requirements concerning the efficient
use and conservation of water resources, including measures identified in the City’s General Plan. Any
potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Therefore, the Project would result in no impacts related to water
supply availability.
c) Would the project result in a determination by the wastewater treatment provider which serves or
may serve the project that it has adequate capacity to serve the project’s projected demand in addition
to the provider’s existing commitments?
467

No Impact. Wastewater treatment in the City generally occurs through private septic tanks, as only
several parcels on the western periphery of the City have access to sanitary sewer. For these several
parcels, the Los Angeles County Sanitation Districts (LACSD) owns, operates, and maintains the sewer
system consisting of gravity sewers, pumping stations, and force mains to collect wastewater from
the Palos Verdes District service area (Sanitation District #5). The LACSD’s Joint Water Pollution
Control Plant (JWPCP) provides the wastewater service for the District service area. It provides
advanced primary and partial secondary treatment for 400 million gallons per day (MGD) of
wastewater and serves a population of approximately 4.8 million people (LACSD 2021). This plant
currently processes 260 MGD; thus, the system has adequate capacity for the Project (CalWater 2021).
Since the Project proposes adoption of two a policy documents, all future development in the City
would require project-specific environmental evaluation in order to determine any potential impacts
related to wastewater. Any future development would also be subject to all applicable State, regional,
and local regulatory requirements concerning the efficient use and conservation of water resources,
including measures identified in the City’s General Plan. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Therefore,
the Project would result in no impacts related to wastewater treatment.
d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local
infrastructure, or otherwise impair the attainment of solid waste reduction goals?
e) Would the project comply with federal, state, and local management and reduction statutes and
regulations related to solid waste?
No Impact. The closest landfill to the City is the Savage Canyon Landfill in Whittier, California. This
landfill has a remaining capacity of 9,510,833 tons and is not expected to close until 2055 (CalRecycle
2021). Since the Project proposes adoption of twoa policy documents, all future development projects
would require an environmental analysis to ensure compliance with the State and local standards and
the federal, State, and local management and reduction statutes and regulations related to solid
waste. Therefore, the Project would have no impact in regard to an increase in solid waste generation
or complying with applicable regulations related to solid waste.

5.20.1 Impact Analysis
a) Would the project impair an adopted emergency response plan or emergency evacuation plan?
No Impact. The entire City is designated as a VHFHSZ by CAL FIRE (CAL FIRE 2011). As mentioned in
Section 5.9, the City’s CWPP identifies the potential evacuation routes described below, which include
options for rapid egress from areas within the City if threatened by a wildfire.
Main Gate at Rolling Hills Road and Palos Verdes Drive North
Crest Gate at Crest Road near Crenshaw Boulevard
Eastfield Gate at Eastfield Drive and Palos Verdes Drive East
Crest Road East (emergency access only)
The SEU and HEU addresses the protection of the existing and future population and development
from both natural and man-made hazards through a number of goals, policies, implementation
programs, principles, and standards. Among these are measures to mitigate the risk from the hazards
of fire. Regardless, potential impacts related to emergency response and evacuation are unique to a
project and cannot be meaningfully determined until a project has been defined. Therefore, future
development in the City would require individual environmental analysis to ensure compliance with
the provisions of the City’s General Plan and CWPP during construction and operation. Any potentially
significant environmental impacts identified from future development would be addressed through
project-specific mitigation measures identified at the time a specific development project is
considered by the City. Thus, the Project would result in no impacts related to the impairment of or
physical interference with an adopted emergency response plan or emergency evacuation plan.
b) Would the project, due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and
thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled
spread of a wildfire?
No Impact. As mentioned above, the entire City is designated a VHFHSZ by CAL FIRE, and a substantial
amount of land in the City is steep hillsides and canyons (CAL FIRE 2011). Although the SEU and HEU
includes measures to mitigate the risk of fire hazards, potential impacts related to fire exacerbation
are unique to a project and cannot be meaningfully determined until a project has been defined. Thus,
future development in the City would require separate environmental analysis to ensure compliance
with the provisions of the City’s General Plan and CWPP during construction and operation. Any
potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Thus, the Project would result in no impacts related to wildfire
exacerbation.

c) Would the project require the installation or maintenance of associated infrastructure (such as roads,
fuel breaks, emergency water sources, power lines, or other utilities) that may exacerbate fire risk or
that may result in temporary or ongoing impacts to the environment?
No Impact. Principal site improvements required upon development of a vacant property in the City
are the undergrounding of electrical lines to the structure, installation of a septic system, and
conformance to the City’s outdoor lighting standards. The entire City is designated a VHFHSZ by CAL
FIRE; however, the SEU includes measures to mitigate the risk of fire hazards. Although not anticipated
under the HEU or the SEU, potential impacts related to utility installation and fire exacerbation are
unique to a project and cannot be meaningfully determined until a project has been defined. Thus,
future development in the City would require separate environmental analysis to ensure compliance
with the provisions of the City’s General Plan and CWPP during construction and operation. Any
potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Thus, the Project would result in no impacts related to wildfire
exacerbation.
d) Would the project expose people or structures to significant risks, including downslope or downstream
flooding or landslides, as a result of runoff, post-fire slope instability or drainage changes?
No Impact. As mentioned above, the entire City is designated a VHFHSZ by CAL FIRE, and a substantial
amount of land in the City is steep hillsides and canyons highly susceptible to landslide risks (CAL FIRE
2011). Although the SEU includes measures to mitigate the risk of fire hazards, potential impacts
related to post-fire instability and drainage changes are unique to a project and cannot be
meaningfully determined until a project has been defined. Thus, future development in the City would
require separate environmental analysis to ensure compliance with the provisions of the City’s
General Plan and CWPP during construction and operation. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Thus, the
Project would result in no impacts related to post-fire slope instability or drainage changes.

c) Does the project have environmental effects which will cause substantial adverse effects on human
beings, either directly or indirectly?
No Impact. As demonstrated throughout this document, the Project would have no impacts to
Aesthetics, Agricultural Resources, Air Quality, Biological Resources, Cultural Resources, Energy,
Geology and Soils, Greenhouse Gas Emissions, Hazards and Hazardous Materials, Hydrology and
Water Quality, Land Use and Planning, Mineral Resources, Noise, Population and Housing, Public
Services, Recreation, Transportation, Tribal Cultural Resources, Utilities and Service Systems, or
Wildfires. Implementation of the City’s HEU and SEU will not create any significant or adverse impacts
and would therefore not contribute to any cumulatively considerable impacts. Potential site-specific
impacts that cannot be known at this time would be addressed in conjunction with any development
proposal submitted for the individual project sites. The Project involves adoption of two a policy
documents consistent with the General Plan and does not include any changes to land use
designations, zoning, building heights and intensities, or residential densities. Therefore, the Project
would have no impacts or cumulatively considerable impacts on the environment or human beings.

Introduction
Safety Element 1
Introduction
The Safety Element provides the City of
Rolling Hills’ (City’s) goals, policies, and
actions to minimize the hazards to safety in
and around Rolling Hills. The Element
evaluates natural and human-caused safety
hazards that affect existing and future
development and provides guidelines for
protecting the community from harm. The
Element describes existing and potential
future conditions and sets policies for
improved public safety. The goal of the Safety
Element is to reduce the risk of injury, death,
property loss, and other hardships to
acceptable levels.
City Setting
Rolling Hills covers an area of approximately
three square-miles on the Palos Verdes
peninsula, approximately 18 miles south of
downtown Los Angeles. The topography of
the city and peninsula area is unique in that it
rises above the Los Angeles Basin with rolling
hills, steep slopes, and canyons. The city itself
is in the San Pedro Hills. Due to its location
near the coast, the area is generally cooler
and has fewer air quality concerns compared
to the nearby Los Angeles Basin. Table 1
summarizes the climatology of the area.
Rolling Hills City Hall
Rolling Hills is a residential community that
consists of large parcels and ranch-style
homes and has a sizable older adult1
population of about 513 (28% of the city’s
total population). Important community
demographic data for Rolling Hills is included
in Table 2. The city is also an equestrian
community, as many of residents are horse
owners or have horses on their property.
Regulatory Setting
Section 65302(g) of the California
Government Code requires that the General
Plans include a Safety Element for the
protection of the community from any
unreasonable risks associated with the effects
of seismically induced surface rupture,
ground shaking, ground failure, tsunami,

seiche, and dam failure; slope instability
leading to mudslides and landslides;
subsidence and other geologic hazards;
flooding, and wildland and urban fire. In
addition, Safety Elements are required to
address non-hazard specific issues such as
peak load water supply, evacuation routes,
and military installations.
Senate Bill 379, adopted on October 8, 2015,
requires cities to include climate change
adaptation and resilience into the general
plan process. To comply with SB 379, this
Safety Element includes a vulnerability
assessment; adaptation and resilience goals,
polices, and objectives; and feasible
implementation measures.
Senate Bill 99, adopted August 30, 2020,
requires the cities to “identify residential
developments in any hazard area identified in
the safety element that does not have at least
two emergency evacuation routes.” SB 99
does not define neighborhood and cities are
expected to define neighborhoods based on
their community.
Relationship to Other Documents
The Rolling Hills Safety Element is one of
several plans that address safety in the City.
The Safety Element must be consistent with
these other plans to ensure the City has a
unified strategy to address safety issues. The
Safety Element includes information and
policies from the following documents to
ensure consistency.
Other General Plan Elements
The Safety Element is one section of the
Rolling Hills General Plan. Other elements
include Land Use, Transportation, Housing,
479
Introduction
Safety Element 3
Conservation, Open Space and Recreation
and Noise. Policies in these other elements
may be related to safety issues. Information
and policies in the Safety Element should not
conflict with those in other elements.
Hazard Mitigation Plan
The City’s Hazard Mitigation Plan includes
resources and information to assist the City of
Rolling Hills, its residents, and public and
private sector organizations in planning for
hazard events. The Plan provides a list of
activities that may assist the City in reducing
risk and preventing loss from future hazard
events. The action items address multi-hazard
issues, as well as activities specifically for
reducing risk and preventing losses relating to
earthquake, land movement, wildfire, and
drought.
Community Wildfire Protection Plan
The City’s Community Wildfire Protection
Plan (CWPP), adopted in July 2020, seeks to
reduce wildfire risk in Rolling Hills. The Plan
was developed collaboratively among
stakeholders including the community, the
City of Rolling Hills, the Rolling Hills
Community Association, and the Los Angeles
County Fire Department, and the Los Angeles
Sheriff’s Department. The Plan includes fire
mitigation and evacuation strategies for the
community.
Critical Facilities and
Infrastructure
Critical facilities are places that provide
emergency services or serve people who
would be impacted by an emergency.
Examples include hospitals, fire stations,
police stations, emergency services facilities,
utility facilities, and communication facilities.
Critical facilities can also include the
transportation system and schools. Due to
the size and composition of Rolling Hills,
many of the critical facilities that serve the
city are located outside of city limits. No areas
in Rolling Hills have been identified as lacking
emergency service. Critical facilities that serve
the city are shown in Figure 1 and include:

Hazards of Concern
Geologic Hazards
Geologic processes that pose a threat to life,
health, property, or infrastructure are
considered geologic hazards. Natural geologic
hazards that have the potential to affect
Rolling Hills include seismic hazards,
landslides, liquefaction, expansive soils, and
weathering. In most cases, these natural
processes cannot be prevented; however, the
magnitude of destruction resulting from
natural geologic hazards can be reduced
through planning policies and measures.
Landslide Hazards
Landslide activity refers to a wide range of
gravity driven downslope earth movement,
including rockslides, rotational slips,
mudslides, and shallow debris flows.
Geological and geomorphological conditions
such as soil type, soil strength, slope angle,
and slope height predispose slopes for failure.
Other factors affecting the susceptibility to
slope failure include the amount of
precipitation, vegetation on the slope,
groundwater seepage, and human
modifications to the slope. Landslides often
result in damage to property and roadways
and can cause them to become unsafe due to
displacement of the subsurface.
Much of the existing development in Rolling
Hills is located on hilly terrain and have a
greater potential to experience landslide
hazards. Many of the canyons in Rolling Hills
exhibit steep slopes with little vegetation
coverage, leaving them susceptible to slope
failure. Figure 2 shows the landslide zones in
the City of Rolling Hills, as mapped by the
California Geological Survey (CGS). Landslide
activity has been well documented in the
region. Relicts of landslides and rockslides are
present throughout the City of Rolling Hills.
2 “Beginning in” is defined as the first noted event of major
rock movement
The following major landslides have occurred
in and adjacent to the city. All are in the
landslide hazards areas identified in Figure 2:
▪ Portuguese Bend Landslide: Beginning in2
1956 over approximately 270 acres in
Rancho Palos Verdes
▪ Abalone Cove Landslide: Beginning in
1974 over 80 acres in Rancho Palos
Verdes
▪ Klondike Canyon Landslide: Beginning in
1979 over to the south near the coastline
▪ Flying Triangle Landslide: Beginning in
1970s or 1980s over approximately 70
acres in the southeast area of the city
The Flying Triangle Landslide, shown in Figure
2, continues to impact the southeast portion
of the city through impacts to private roads
and above-ground utility lines. This area is
relatively unsuitable for development due to
the ongoing changes in topography.
Seismic Hazards
Rolling Hills is in a seismically active region of
southern California. The last major
earthquake in the Los Angeles area was the
5.1 magnitude La Habra earthquake in 2014.
Rolling Hills is within 50 miles of the Whittier
fault, Newport-Inglewood fault, Palos Verdes
fault, Malibu Coast fault, Cabrillo fault, Santa
Monica fault, and Redondo Canyon fault.
Analysis of seismic data from the region
indicates that the Whittier and Newport-
Inglewood faults may generate a maximum
credible earthquake of magnitude 7.2 and
7.4, respectively (SCEC 2013). Figure 3 shows
the faults in the vicinity of Rolling Hills.
Typically, seismic shaking and fault rupture
are primary hazards as they occur as a direct
result of the interaction between the seismic
wave energy and the earth’s surface.
Secondary hazards, such as liquefaction and
earthquake-induced landslides, occur as a
result of the primary earthquake hazards.

Hazards of Concern
Safety Element 9
Often, earthquake activity can result in other
effects such as building damage/collapse,
infrastructure failure, pipeline breakage, and
damage to transportation and
communication facilities. The size of the
earthquake and distance from the fault
rupture zone typically determine the severity
of these events.
Seismic Shaking
Seismic shaking, or ground shaking, refers to
the movement of the earth’s surface resulting
from the energy release by an earthquake.
Seismic shaking is typically the primary cause
of property damage resulting from
earthquake activity. Seismic shaking can
destroy buildings, roadways, powerlines, and
pipelines. Energy transmitted through the
ground can travel hundreds of miles and may
cause damage in many locations
simultaneously. Closer proximity to the fault
rupture area results in stronger shaking in
that location.
The amount of ground shaking that occurs in
a location depends on the magnitude of the
earthquake, the distance from the epicenter,
and local soil conditions. The intensity of
ground shaking is related to the peak ground
velocity during an earthquake. As shown in
Figure 4, the earthquake shaking potential for
Rolling Hills is low to moderate. The intensity
of seismic shaking is measured using the
Modified Mercalli scale.
According to the CGS, an active fault is one
that has experienced surface movement in
the past 11,000 years. The city is located near
a number of active faults, including the
Cabrillo Fault in city limits. Table 3 includes a
list of nearby faults, their respective distance
from the city, the maximum credible
earthquake generated from each fault, and
the likelihood of earthquake occurrence in
each case.
The San Andreas fault is located
approximately 80 miles to the east of Rolling
Hills. Although the San Andreas fault is
located at a greater distance from the city,
seismic shaking originating from earthquakes
occurring along the San Andreas fault poses a
threat to the city. Figure 3 identifies the
active and inactive faults located in the city
and vicinity.
Fault Rupture
Fault Rupture occurs when seismic movement
on a fault break through the earth’s surface.
Hazards related to fault rupture arise when
structures are built near or on top of an active
fault. While there are a number of seismically
active faults in the city and region, there are
no active faults with the potential for ground
rupture, defined by the Alquist-Priolo
Earthquake Fault Zoning Act and delineated
by CGS. Figure 3 shows the designated
Alquist-Priolo study zones, the closest of
which is the Newport-Inglewood Fault
approximately nine miles northeast of the
city.

Liquefaction and Settlement
Liquefaction is a ground failure phenomenon
that occurs as a result of a seismic event.
Liquefaction increases water content in
surface soils until the soil reaches a semi-
liquid state, contributing to a reduction in
support, and ultimately resulting in shifting or
subsidence of buildings and utilities. Ground
failure typically occurs when the following
conditions exist:
▪ Loose, unconsolidated granular soils
▪ Shallow groundwater
▪ Strong seismic ground shaking
While Rolling Hills has moderate to high
seismic shaking potential, the subsurface soils
generally lack saturated alluvial deposits and
thick, granular soils. Figure 5 shows the
liquefaction hazard areas, which are in the
low-lying areas to the east and north,
generally surrounding the Los Angeles Harbor
and Harbor Lake. Liquefaction potential for
Rolling Hills is low, as shown in Figure 5.
Earthquake Induced Landslides
Ground failure or destabilization of slopes
resulting from an earthquake can also occur
following seismic activity in the form of
Earthquake-Induced Landslides. Earthquake-
induced landslides typically occur in areas
with steep slopes or unstable soil conditions.
As discussed above under Landslide Hazards,
the risk of landslide activity in Rolling Hills is
high. Much of the city overlies areas that have
been identified as landslide zones by the CGS.
Risk of landslide activity increases following
rainfall events that result in saturated soils.
Both shallow and deep seeded landslides
have historically occurred in the city.
Flooding
Rolling Hills participates in the Federal
Emergency Management Agency’s (FEMA)
National Flood Insurance Program. According
to the FEMA flood maps, the city is not
located in a flood hazard area and currently
has a less than 0.2 percent annual chance to
be inundated by flood waters as a result of a
storm event (FEMA 2008). Overall, the city is
not in any immediate risk from flooding
caused by overflowing water bodies or heavy
rains. However, runoff and minor flooding
pose a risk if drainage systems fail along
canyon bottoms, where natural drainage
leads.
Dam Inundation
No water storage facilities that the State of
California identifies as dams are located in
Rolling Hills. Just outside city limits are three
water storage facilities identified as dams,
which include:
▪ Palos Verdes Reservoir. Owned by the
Metropolitan Water District of Southern
California and located at the southeast
corner of Palos Verdes Drive East and
Palos Verdes Drive North. According to
the California Department of Water
Resources, the reservoir can hold
approximately 1,100 gallons of water and
has an extremely high downstream
hazard.
▪ 10 MG Walteria and 18 MG Walteria.
Two reinforced concrete tanks which are
owned by the City of Torrance and
located at Crenshaw Boulevard and Crest
Road. The tanks can hold 31 and 58 acre-
feet (AF) of water, respectively.
Senate Bill 92, adopted in 2017, is a new dam
safety requirement that requires dam owners
to map the downstream inundation areas for
dams governed by the Department of Water
Resources. Figure 6 shows the inundation
areas for the nearby water storage facilities.
Due to their locations and the topography of
the area, the inundation areas do not enter or
affect any portion of the city.

Wildland and Urban Fires
The entire City of Rolling Hills is designated a
Very High Fire Hazard Severity Zone (VHFHSZ)
by the California Department of Forestry and
Fire Protection (CalFire), as shown in Figure 7.
Rolling Hills terrain is comprised of several
large and steep canyons that limit and
challenge vegetation management and
present conditions where a fire can quickly
travels up and downslope to nearby homes.
Due to the rural nature and large residential
lots, many homes are surrounded by more
substantial vegetation and dense brush than
in more suburban settings. The bridle trails
for hikers and equestrian access also contain
dense vegetation and management
difficulties, which contributes to the fire risk
of the city. Electrical power lines pose a
hazard to starting fires in the city if lines are
not automatically de-energized when
knocked down by extreme weather or if the
surrounding vegetation is not adequately
managed.
There is a history of fires in the city and the
surrounding Palos Verdes Peninsula. Three
major fires have been documented on the
Peninsula and in the city in:
▪ 1923: an estimated 4,000 acres burned in
Palos Verdes Hills
▪ 1945: 3,000 acres burned
▪ 1973: approximately 900-925 acres
burned, 12 homes destroyed, and 10
homes damaged
▪ 2005: 212 acres burned near Del Cero
Park
▪ 2009: 230 acres burned, 6 homes
damaged, and forced 1,200 residents on
the Peninsula to evacuate
▪ 2015: 3 acres burned

For many of the developed residences in the
city that are vulnerable to fires, their risk may
increase with construction techniques that
may not meet current wildfire standards.
Rolling Hills Building Code and Los Angeles
County Fire Department, under the VHFHSZ
standards, require new development to
include more stringent design and material
standards for roofing, eaves, and rafter tails
as well as exterior finishes and fire buffer
zones. While compliance with these
standards reduces the vulnerability to new
structures, existing structures that have not
complied with these standards may be
susceptible to undue fire risk.

Hazardous Materials
According to the Department of Toxic
Substances Control (DTSC), there are no
hazardous waste sites or facilities in Rolling
Hills (DTSC 2020). The city and surrounding
area do not contain heavy industrial uses that
would create a hazardous material risk in the
event of a spill, release, or natural disaster.
The city is not located near any major transit
routes involving transport of a substantial
quantity of hazardous material through the
city. However, the nearby oil refineries
(located along Sepulveda Boulevard
approximately six miles northeast) and Port
operations (located approximately three
miles to the east) could create air quality
impacts if wind patterns and release events
occur. Air quality impacts are discussed in the
Open Space and Conservation Element of the
Rolling Hills General Plan.
Community
Communication
Emergency Response and
Evacuation
Police Response and Crime
The Los Angeles County Sheriff’s Department
is contracted with the city to provide police
services and protection to the city. The
Lomita Station of the Sheriff’s Department
located at 26123 Narbonne Avenue serves
the city.
According to the Lomita Station crimes report
from January 1, 2020, through December 31,
2020, Rolling Hills had 7 reported crimes
(LACSD 2020). The crimes were related to
theft, burglary, and arson. Outside the city
limits and in the Lomita District, 401 crimes
were reported during this same period, 79 of
which were violent crimes (LACSD 2021). The
difference in crimes in the city and the
surrounding area is attributed to the private
nature of the city. There are three entrances
to the city, all of which are gated and staffed
24 hours a day. Visitors are required to be on
a resident’s guest list to enter city limits,
reducing crime in the city and demand on Los
Angeles County Sheriff’s Department.
Fire Response
The Los Angeles County Fire Department
provides emergency operations support to
the City and participates in the California
mutual aid system. Mutual aid is emergency
assistance that is dispatched upon request
across jurisdictional boundaries. Fire Station
56, located at 12 Crest Road West, serves the
city under Battalion 14, which also serves the
remaining Palos Verdes Peninsula, Lomita,
and Avalon Canyon. Fire response constraints
in the city include ability to access certain
homes or areas due to inadequate road
widths for fire maneuvering. One of the major
topics of concern related to fire response in
the city relates to vegetation clearing along
roadways. Ten-foot clearance on each side of
the roadway, especially the limited access
roads, is important for fire response and
evacuation during a fire, according to Scott
Hale, Assistant Fire Chief.
Evacuation Strategies and Routes
Because a variety of hazards could affect city
residents, it is vital to identify critical routes
for evacuation in the event of a major event.
Senate Bill 99, adopted August 30, 2020,
requires cities to “identify residential
developments in any hazard area identified in
the safety element that does not have at least
two emergency evacuation routes.” Due to
the size of Rolling Hills and that it has four
evacuation routes, no neighborhoods have
been identified as not having two evacuation
routes. As shown on the Figure 8, the
evacuation routes also connect to major
494

roadways in the area that are multi-
directional such as Crenshaw Boulevard, Palos
Verdes Drive North and Palos Verdes Drive
East.
Figure 8 identifies the existing evacuation
routes in the city, which are:
▪ Main Gate at Rolling Hills Road and Palos
Verdes Drive North
▪ Crest Gate at Crest Road near Crenshaw
Blvd
▪ Eastfield Gate at Eastfield Drive and Palos
Verdes Drive East
▪ Crest Road East Gate at the end of Crest
Road East
Crest Road East Gate has been updated with a
motor and has no guards. This gate is
available as an emergency exit to the city
during emergencies. The City’s recently
adopted CWPP establishes evacuation
strategies and methodologies, including:
▪ Using the City’s Block Captains3 as
important coordinators for residents
▪ Communication goals between the City,
emergency responders, Rolling Hills
Community Association, and residents
▪ Details for residents regarding how
people get notified during an evacuation
▪ Responsibilities and operations of the
Emergency Operations Center
Disease Prevention
As evidenced by the COVID-19 pandemic,
unforeseen infectious diseases can be
disastrous for communities, especially
vulnerable groups such as older adults, and
people with compromised immune systems.
The City worked diligently during the
pandemic to minimize risk to community
members. The Block Captains regularly
checked in on old adults in the community,
Fire Station Trail
3 The Rolling Hills Block Captain Program is a city-sponsored,
resident-based community program of volunteers. Their role is
to get to know neighbors, help them to prepare for an
emergency, and be a liaison between first responders and City
of Rolling Hills during an emergency.

finding out what residents needed, helping
run errands, and providing hand sanitizer
Additionally, the City disseminated
information regularly including where to buy
groceries at the beginning of the pandemic,
testing information, and more. Policies
regarding infectious disease can help expedite
recovery and prepare the community for
future risks.
Climate Change
Climate change is expected to affect future
occurrences of natural hazards in and around
Rolling Hills. Some hazards are projected to
become more frequent and intense in the
coming decades, and in some cases, climate
impacts have already begun.
In developing the Safety Element, the City
competed a Climate Change Vulnerability
Assessment consistent with Government
Code Section 65302(g), which assesses how
the populations and assets in Rolling Hills are
vulnerable to different climate hazards. The
full Climate Change Vulnerability Assessment
can be found in Appendix A: Existing
Conditions Report. According to the
Vulnerability Assessment, the city is most
vulnerable to wildfire impacts, extreme heat,
and landslide impacts from climate change.
According to the Vulnerability Assessment
and the California’s Fourth Climate Change
Assessment, Rolling Hills can expect the
following changes to natural hazard events:
▪ Projected annual average maximum
temperature is expected to increase in
Rolling Hills between 1.8- and 6.6-degrees
Fahrenheit (°F) compared to 1990,
depending on the greenhouse gas (GHG)
emissions scenario.4
4 The Vulnerability Assessment uses two GHG emissions
scenarios: Representative Concentration Pathway (RCP) 4.5
and RCP 8.5. RCP 4.5 describes a scenario in which GHG
▪ Extreme heat events are also expected to
increase in Rolling Hills. The annual
number of average extreme heat days is
projected to increase from a baseline of 4
between 1950 and 2005 to 8 or 14
between 2030 and 2099, depending on
the GHG emissions scenario.
▪ Although only small changes in average
precipitation are projected, the Los
Angeles Region, which includes Rolling
Hills, is expected to experience dry and
wet precipitation extremes and higher
frequency and severity of storms.
Increasing storm intensity may
exacerbate landslide hazards in the city.
Warmer and drier conditions state-wide
could increase the prevalence of drought
conditions that could impact Rolling Hills.
▪ Wildfire is projected to increase over all
of southern California.
Vulnerable Populations
and Assets
As climate change occurs, communities will
be affected to varying degrees and impacts
depending on the hazard as well as how
sensitive the communities are to impacts.
Virtually all people and assets in a community
will be affected by climate change in some
way, but some communities may be more
sensitive. The Vulnerability Assessment
identified the following sensitivities:
Populations
▪ Children. Approximately 6.6 percent of
the total population in Rolling Hills are
ten years old or younger.
▪ Persons in Poverty. This is identified for
people living in households with an
income below the poverty limit, which is
$26,200 for a household of four people.
There are approximately 26 people in
emissions peak around 2050 and then decline. RCP 8.5 is the
scenario in which GHG emissions continue to rise through 2050
before leveling off around 2100.
497
Climate Change
Safety Element 21
Rolling Hills who live in poverty, or
approximately 1.6 percent of the total
population for whom poverty status can
be determined.
▪ Persons with Chronic Health Conditions.
These are people who have a long-term
or permanent health condition that can
create regular challenges in their day-to-
day lives. These health problems include
obesity, cancer, heart disease, and
arthritis. In addition, those with any kind
of disability, including mobility challenges,
hearing, or vision impairments,
behavioral disabilities, and challenges
living independently or taking care of
themselves. Approximately 11.5 percent
of the population have identified having a
disability.
▪ Renters. These are people who live in
homes that they (or the head of their
household) do not own. Approximately 24
housing units, or 4 percent of the housing
units in Rolling Hills, are renter-occupied.
▪ Older Adults. These are persons 65 years
or older are more at risk for climate
change impacts, especially those living
alone. 28 percent of the population of
Rolling Hills are over 65 years, and 15
percent of those over 65 years live alone.
▪ Limited English Proficiency.
Approximately three percent of
households have identified being limited
English-speaking. Of those, a majority
spoke Asian and Pacific Island languages
and Spanish.
Infrastructure
▪ Access Roads. These roadways are one of
a few, or the only, ways in and out of
some communities or neighborhoods.
The single or limited number of entry and
exit points does not make the road itself
more vulnerable than other roads, but
loss of these roadways can effectively cut
off large numbers of people from other
areas in the Palos Verdes Peninsula and
the rest of Los Angeles County.
Portuguese Bend Road and Crest Road
are the primary access roads into and out
of the city.
▪ Bridle Trails. Throughout the community
are over 25 miles of trails available to
residents and non-city residents who
obtain permits. The trails are maintained
by the Rolling Hills Community
Association and located primarily in
canyon areas.
▪ Electrical Substations. Electrical
substations are facilities that convert
electricity from one voltage to another,
making it suitable for long-distance
transmission or for use by homes,
businesses, and other electrical
customers. There are no electrical
substations located in city limits, but
three are located near the city in Rancho
Palos Verdes and owned/operated by
Southern California Edison.
▪ Electrical Utility Lines. These lines
transmit and deliver electricity from
Southern California Edison to the city. The
city has both underground and overhead
electric utility lines.
▪ Natural Gas Transmission Pipelines.
Natural gas pipelines carry large volumes
of natural gas between communities.
There are no transmission lines in the
city. One transmission line ends at the
intersection of Rolling Hills Road and
Palos Verdes Drive North, adjacent to city
limits.
▪ Water Reservoirs and System. The
system that stores and supplies drinking
water for residents. Palos Verdes Water
District of the California Water Service
supplies water to Rolling Hills. There are
two California Water Service water
reservoirs in the city limits.
Services
▪ Public Safety Response. Public safety
services are provided by law enforcement
498
City of Rolling Hills
Rolling Hills General Plan
22
and fire agencies. These agencies include
the Los Angeles County Sheriff and Fire
Departments.
▪ Water Services. These services involve
treating and transporting water to be
used by customers and transporting and
treating wastewater so it can be safely
released into the environment. California
Water Service provides drinking water to
the city.
▪ Energy Delivery. Energy services in
Rolling Hills include electricity and natural
gas delivered through utility lines from
Southern California Edison and Southern
California Gas Company.
Vulnerability Assessment
Results
The Vulnerability Assessment indicates that
the city’s populations, infrastructure, and
services are most vulnerable to wildfire,
extreme heat, and extreme precipitation
events.
Populations
Vulnerable populations such as older adults,
residents with chronic health conditions, and
those with financial trouble are most at risk to
extreme heat and wildfire impacts.
28 percent of the city’s population is over 65
years. Older adults do not adjust as well as
young people to sudden changes in
temperature and are more likely to have
medical conditions that can worsen with
extreme heat (CDC 2017a). Older adults who
are living alone are even more at risk as the
actions necessary to mitigation extreme heat
are more difficult alone. Getting water,
changing clothes, showering, or turning on
the air conditioner may be more difficult for
older adults with physical disabilities and do
not have a partner to assist them. Extreme
heat can be highly dangerous to persons with
chronic health conditions, because very high
temperatures can exacerbate diabetes,
cardiovascular conditions, respiratory
ailments, and other diseases. Some of these
people have weakened immune systems
which can make them more likely to contract
illnesses and vulnerable to human health
hazards. In addition, they may be taking
medications that make the effects of extreme
heat worse (CDC 2017b). While there are not
many households in poverty in the city, those
who are have limited financial resources to
upgrade their homes to have air conditioning
to better resist extreme heat.
Older adults, residents with chronic health
conditions, and those with financial trouble
are the populations most at risk to wildfire
impacts. Older adults are almost three times
more likely to die in a fire than the overall
population (USFA 2017), and typically have
increased mobility or mental health issues.
Therefore, older adults, especially those in
the city living alone, have more difficulties
evacuating to safe areas when there is a
need. Those in Rolling Hills with limited
financial resources are more unlikely to
retrofit their homes to better resist climate-
related hazards such as wildfires. In addition
to direct impacts, indirect impacts such as
poor air quality also creates public health
hazards to the city. Recent California wildfires
in August and September 2020 had areas of
California recording the worst air quality in
the world and highlighted the hazards of
secondary impacts from wildfires, which
could impact the city from fires throughout
the State. Older adults and individuals with
chronic health conditions are likely to be
impacted most by these secondary impacts.
Also, those with limited finances or without
air conditioning would be impacted by
secondary smoke impacts that occur during
local and regional wildfires.
Infrastructure
Access roads, residential structures, and
community facilities and government
buildings are the most vulnerable
499
Climate Change
Safety Element 23
infrastructure to wildfire and extreme
precipitation impacts from climate change.
All city infrastructure is located in a VHFHSZ.
Portuguese Bend Road and Crest Road are
critical for access to and evacuation from
many areas of the city. Wildfires may not
significantly damage the infrastructure, but
they could result in closure or the inability to
travel on them during wildfire events, which
can isolate areas of the city and create severe
health and safety risks. Wildfires are unlikely
to substantially damage trails directly, but
they can force widespread trail closures
which are an important asset to the
community.
The greatest potential impact of life and well-
being would be to residential structures,
which are the primary structures in the city.
In addition, impacts to Rolling Hills
Community Association and City Hall
structures would impact community functions
and government services.
Critical infrastructure most at risk in Rolling
Hills to minor flooding impacts and landslides
from increased storms would be access roads,
bridle trails, electrical utility lines, and water
systems. Because Portuguese Bend Road and
Crest Road are critical for access to and
evacuation from the city, any damage or
closure can effectively isolate areas of the
city, potentially creating severe health and
safety risks. Bridle trails are predominantly
located in canyon areas, which would be
more susceptible to flooding and landslides.
Landslides could impact utilities, as seen in
the existing Flying Triangle Landslide area,
which has moved utility lines above ground in
certain areas due to the continuous
movement of the earth in this area. Due to
the limited accessibility of the city, there is a
medium potential for impacts to access roads
and bridle trails and a low potential impact
for the remaining vulnerable infrastructure.
Services
Energy delivery, specifically electricity
delivery, could be impacted from increased
wildfires. Direct impacts to Southern
California Edison electricity transmission
infrastructure could impact power in the city.
In addition, utility companies have begun
shutting off power to areas to avoid wildfires
during times when weather creates high
wildfire risk. Public safety services could be
strained during wildfire events, which are
expected to increase.
Overall, climate change impacts from wildfire
are projected to have the greatest potential
impact to the city.

Summary
Key Findings
The city is most at risks to impacts from wildfire, extreme heat, and landslide events, which are
all anticipated to increase as a result of climate change impacts. Vulnerable populations such as
older adults and residents with chronic health conditions are most at risk to extreme heat and
wildfire impacts. Access roads and residential structures are also the most vulnerable to wildfire
and landslide impacts from climate change.
The city has a moderate risk for shaking potential from earthquakes.
Flood risks in the city are minimal and limited to natural drainage areas in the canyons.
Vegetation clearing along roadways is a concern and major goal for improving fire response and
evacuation in the city.
Evacuation strategies and education are important to reduce risk from hazards due to the lack
of evacuation routes in the city and the remote development on private roads. The need to
further analyze evacuation routes and access is one of the most recent changes in Safety
Element requirements. A key opportunity for the Safety Element update is to address specific
evacuation needs.
The City has recently adopted a number of planning documents such as the Hazard Mitigation
Plan and Community Wildfire Protection Plan, which seek to reduce the risk of hazards in the
city. An opportunity for the Safety Element update would be to utilize existing
recommendations from the Community Wildfire Protection Plan as implementation tools for the
Safety Element.

Introduction
Section 65302(g) of the California Government Code requires that the General Plan include a Safety
Element for the protection of the community from any unreasonable risks associated with the
effects of seismically induced surface rupture, ground shaking, ground failure, tsunami, seiche, and
dam failure; slope instability leading to mudslides and landslides; subsidence and other geologic
hazards; flooding, wildland and urban fire, and climate change adaptation and resilience. In
addition, Safety Elements are required to address non-hazard specific issues such as peak load water
supply, evacuation routes, and military installations.
This Existing Conditions Report is a comprehensive assessment of natural and man-made hazards
for the City of Rolling Hills. The report serves as the foundation for the Safety Element and includes
detailed Geographic Information System (GIS) hazard mapping and analyses. The following City
plans were also utilized for this report along with existing local data from governmental agencies
and scientific research: Hazard Mitigation Plan, Community Wildfire Protection Plan, and the
existing Safety Element.
Setting
Rolling Hills covers an area of approximately three square-miles on the Palos Verdes peninsula,
approximately 18 miles south of downtown Los Angeles. The topography of the city and peninsula
area is unique in that it rises above the Los Angeles Basin with rolling hills, steep slopes, and
canyons. The city itself is located in the San Pedro Hills. Due to its location near the coast, the area is
cooler and has fewer air quality concerns compared to the nearby Los Angeles Basin. Table 1
summarizes the climatology of the area.

Rolling Hills is a residential community that consists of large parcels and ranch-style homes and has
a sizable older adult 1 population of about 513 (28% of the city’s total population). The city is also an
equestrian community, as many of residents are horse owners or have horses on their property.
Important community demographic data for Rolling Hills is included in Table 2.

Critical Facilities and Infrastructure
Critical facilities are places that provide emergency services or serve people who would be impacted
by an emergency. Examples include hospitals, fire stations, police stations, emergency services
facilities, utility facilities, and communication facilities. Critical facilities can also include the
transportation system and schools. Due to the size and composition of Rolling Hills, most of the
critical facilities that serve the city are located outside of City limits. Critical facilities that serve the
city are shown in Figure 1 and include:

Hazards of Concern
Geologic Hazards
Geologic processes that pose a threat to life, health, property, or infrastructure are considered
geologic hazards. Natural geologic hazards that have the potential to affect Rolling Hills include
seismic hazards, landslides, liquefaction, expansive soils, and weathering. In most cases, these
natural processes cannot be prevented; however, the magnitude of destruction resulting from
natural geologic hazards can be reduced through planning policies and measures.
Landslide Hazards
Landslide activity refers to a wide range of gravity driven downslope earth movement, including
rockslides, rotational slips, mudslides, and shallow debris flows. Geological and geomorphological
conditions such as soil type, soil strength, slope angle, and slope height predispose slopes to failure.
Other factors affecting the susceptibility to slope failure include the amount of precipitation,
vegetation on the slope, groundwater seepage, and human modifications to the slope. Landslides
often result in damage to property and roadways and can cause them to become unsafe due to
displacement of the subsurface.
A majority of the existing development in Rolling Hills is located on hilly terrain and have a greater
potential to experience landslide hazards. Many of the canyons in Rolling Hills exhibit steep slopes
with little vegetation coverage, leaving them susceptible to slope failure. Figure 2 shows the
landslide zones within the City of Rolling Hills, as mapped by the California Geological Survey.
Landslide activity has been well documented in the region. Relicts of landslides and rockslides are
present throughout the City of Rolling Hills. The following major landslides have occurred within and
adjacent to the city. All are within the landslide hazards areas identified in Figure 2:
Portuguese Bend Landslide: Beginning in 2 1956 over approximately 270 acres in Rancho Palos
Verdes
Abalone Cove Landslide: Beginning in 1974 over 80 acres in Rancho Palos Verdes
Klondike Canyon Landslide: Beginning in 1979 over to the south near the coastline
Flying Triangle Landslide: Beginning in 1970s or 1980s over approximately 70 acres in the south
area of the city
The Flying Triangle Landslide continues to impact the southeast portion of the city through impacts
to private roads and requiring above-ground utility lines. This area is relatively unsuitable for
development due to the ongoing changes in topography.
Seismic Hazards
Rolling Hills is located in a seismically active region of southern California. The last major earthquake
in the Los Angeles area was the 5.1 magnitude La Habra earthquake in 2014. Rolling Hills is located
within 50 miles of the Whittier fault, Newport-Inglewood fault, Palos Verdes fault, Malibu Coast
2 “Beginning in” is defined as the first noted event of major rock movement

fault, Cabrillo fault, Santa Monica fault, and Redondo Canyon fault. Analysis of seismic data from the
region indicates that the Whittier and Newport-Inglewood faults may generate a maximum credible
earthquake of magnitude 7.2 and 7.4, respectively (Southern California Earthquake Center 2013).
Figure 3 shows the faults in the vicinity of Rolling Hills.
Typically, seismic shaking and fault rupture are primary hazards as they occur as a direct result of
the interaction between the seismic wave energy and the earth’s surface. Secondary hazards, such
as liquefaction and earthquake-induced landslides, occur as a result of the primary earthquake
hazards. Often, earthquake activity can result in other effects such as building damage/collapse,
infrastructure failure, pipeline breakage, and damage to transportation and communication
facilities. The size of the earthquake and distance from the fault rupture zone typically determine
the severity of these events.
Seismic Shaking
Seismic shaking, or ground shaking, refers to the movement of the earth’s surface resulting from the
energy release by an earthquake. Seismic shaking is typically the primary cause of property damage
resulting from earthquake activity. Seismic shaking has the ability to destroy buildings, roadways,
powerlines, and pipelines. Energy transmitted through the ground has the potential to travel
hundreds of miles and may cause damage in many locations simultaneously. Closer proximity to the
fault rupture area results in stronger shaking in that location.
The amount of ground shaking that occurs in a location is dependent on the magnitude of the
earthquake, the distance from the epicenter, and local soil conditions. The intensity of ground
shaking is related to the peak ground velocity during an earthquake. According to the CGS Map
Sheet 48, the earthquake shaking potential for Rolling Hills is moderate. The intensity of seismic
shaking is measured using the Modified Mercalli scale.
According to the California Geologic Survey, an active fault is one that has experienced surface
movement in the past 11,000 years. The city is located near a number of active faults, including the
Cabrillo Fault within city limits. Table 3 includes a list of nearby faults, their respective distance from
the city, the maximum credible earthquake generated from each fault, and the likelihood of
earthquake occurrence in each case.
Table 3 Faults Located within 50 Miles of Rolling Hills
Fault Name Approximate Distance from Rolling Hills
Whittier 25 miles east
Newport-Inglewood 9 miles east
Palos Verdes <1 mile north
Malibu Coast 20 miles northwest
Cabrillo Located within the City boundaries in the southwest
Santa Monica 20 miles north-northwest
The San Andreas fault is located approximately 80 miles to the east of Rolling Hills. Although the San
Andreas fault is located at a greater distance from the city, seismic shaking originating from
earthquakes occurring along the San Andreas fault poses a threat to the city. Figure 3 identifies the
active and inactive faults located within the city and vicinity.
531
Hazards of Concern
Existing Conditions Report 9
Fault Rupture
Fault Rupture occurs when seismic movement on a fault breaks through the earth’s surface. Hazards
related to fault rupture arise when structures are built near or on top of an active fault. While there
are a number of seismically active faults in the city and region, there are no active faults with the
potential for ground rupture, defined by the Alquist-Priolo Earthquake Fault Zoning Act and
delineated by CGS. Figure 3 shows the designated Alquist-Priolo study zones, the closest of which is
the Newport-Inglewood Fault approximately nine miles northeast of the city.
Liquefaction and Settlement
Liquefaction is a ground failure phenomenon that occurs as a result of a seismic event. Liquefaction
increases water content in surface soils until the soil reaches a semi-liquid state, contributing to a
reduction in support, and ultimately resulting in shifting or subsidence of buildings and utilities.
Ground failure typically occurs when the following conditions exist:
Loose, unconsolidated granular soils
Shallow groundwater
Strong seismic ground shaking
While the Rolling Hills has moderate to high seismic shaking potential, the subsurface soils generally
lack saturated alluvial deposits and thick, granular soils. Figure 4 shows the liquefaction hazard
areas, which are located in the low-lying areas to the east and north, generally surrounding the Los
Angeles Harbor and Harbor Lake. Liquefaction potential for Rolling Hills is low, as shown in Figure 4.
Earthquake Induced Landslides
Ground failure or destabilization of slopes resulting from an earthquake can also occur following
seismic activity in the form of Earthquake-Induced Landslides. Earthquake-induced landslides
typically occur in areas with steep slopes or unstable soil conditions. As discussed above under
Landslide Hazards, the risk of landslide activity in Rolling Hills is high. Much of the city overlies areas
that have been identified as landslide zones by the California Geological Survey. Risk of landslide
activity increases following rainfall events that result in saturated soils. Both shallow and deep
seeded landslides have historically occurred in the city.
Flooding
Rolling Hills participates in the Federal Emergency Management Agency’s (FEMA) National Flood
Insurance Program. According to the FEMA flood maps, the city is not located in a flood hazard area
and currently has a less than 0.2 percent annual chance to be inundated by flood waters as a result
of a storm event (FEMA 2008). Overall, the city is not in any immediate risk from flooding caused by
overflowing water bodies or heavy rains. However, runoff and minor flooding pose a risk if drainage
systems fail along canyon bottoms, where natural drainage leads to.

Dam Inundation
No water storage facilities that the State of California identifies as dams are located in Rolling Hills.
Just outside city limits are three water storage facilities identified as dams, which include:
Palos Verdes Reservoir: Owned by the Metropolitan Water District of Southern California and
located at the southeast corner of Palos Verdes Drive East and Palos Verdes Drive North.
According to the California Department of Water Resources, the reservoir can hold
approximately 1,100 gallons of water and has an extremely high downstream hazard.
10 MG Walteria and 18 MG Walteria: Two reinforced concrete tanks which are owned by the
City of Torrance and located at Crenshaw Boulevard and Crest Road. The tanks can hold 31 and
58 acre-feet (AF) of water respectively.
Senate Bill 92, adopted in 2017, is a new dam safety requirement that requires dam owners to map
the downstream inundation areas for dams governed by the Department of Water Resources.
Figure 5 shows the inundation areas for the nearby water storage facilities. Due to their locations
and the topography of the area, the inundation areas do not enter or affect any portion of the city.
Wildland and Urban Fires
The entire City of Rolling Hills is designated a Very High Fire Hazard Severity Zone (VHFHSZ) by the
California Department of Forestry and Fire Protection (CalFire), as shown in Figure 6. Rolling Hills
terrain is comprised of several large and steep canyons that limit and challenge vegetation
management and present conditions where a fire can quickly travels up and downslope to nearby
homes. Due to the rural nature and large residential lots, many homes are surrounded by
substantial vegetation and dense brush than in more suburban settings. The bridle trails for hikers
and equestrian access also contain dense vegetation and management difficulties, which
contributes to the fire risk of the city. Electrical power lines pose a hazard to starting fires in the city
if lines are not automatically de-energized when knocked down by extreme weather or if the
surrounding vegetation is not adequately managed.
There is a history of fires in the city and the surrounding Palos Verdes Peninsula. Three major fires
have been documented on the Peninsula and in the city in:
1973: almost 1,000 acres burned, and 13 homes destroyed
2005: 212 acres burned near Del Cero Park
2009: 230 acres burned and forced 1,200 residents on the Peninsula to evacuate
For many of the developed residences in the city that are vulnerable to fires, their risk may increase
with the presence of construction techniques that may not meet current wildfire standards. Rolling
Hills Building Code and Los Angeles County Fire Department, under the VHFHSZ standards, require
new development to include more stringent design and material standards for roofing, eaves, and
rafter tails as well as exterior finishes and fire buffer zones. While compliance with these standards
reduces the vulnerability to new structures, existing structures that have not complied with these
standards may be susceptible to undue fire risk.

Hazardous Materials
According to the Department of Toxic Substances Control (DTSC), there are no hazardous waste
sites or facilities in Rolling Hills (DTSC 2020). The city and surrounding area do not contain heavy
industrial uses that would create a hazardous material risk in the event of a spill, release, or natural
disaster.
The city is not located near any major transit routes involving transport of a substantial quantity of
hazardous material through the city. However, the nearby oil refineries (located along Sepulveda
Boulevard approximately six miles northeast) and Port operations (located approximately three
miles to the east) could create air quality impacts if wind patterns and release events occur. Air
quality impacts are discussed in the Open Space and Conservation Element of the Rolling Hills
General Plan.
Emergency Response and Evacuation
Police Response and Crime
The Los Angeles County Sheriff’s Department is contracted with the city to provide police services
and protection to the city. The Lomita Station of the Sheriff’s Department located at 26123
Narbonne Avenue, approximately 1.5 miles northeast of the Portuguese Bend Road entrance, serves
the city.
According to the Lomita Station crimes report from January 1, 2020, through June 30, 2020, Rolling
Hills had three reported crimes (LACSD 2020). The crimes were related to theft, assault, and
burglary. Outside the city limits and in the Lomita District, 433 crimes were reported during this
same period, 71 of which were violent crimes (LACSD 2020). The difference in crimes in the city and
the surrounding area is attributed to the private nature of the City. There are three entrances to the
city, all of which are gated and staffed 24 hours a day. Visitors are required to be on a resident’s
guest list in order to enter city limits. This reduces crime within the city and demand on Los Angeles
County Sheriff’s Department.
Fire Response
The Los Angeles County Fire Department provides emergency operations support to the City. Fire
Station 56, located at 12 Crest Road West, serves the city under Battalion 14, which also serves the
remaining Palos Verdes Peninsula, Lomita, and Catalina Island. Fire response constraints in the city
include ability to access certain homes or areas due to inadequate road widths for fire maneuvering.
One of the major topics of concern related to fire response in the city relates to vegetation clearing
along roadways. Ten-foot clearance on each side of the roadway, especially the limited access
roads, is important for fire response and evacuation during a fire, according to Scott Hale, Assistant
Fire Chief.
Evacuation Strategies and Routes
Because a variety of hazards could affect city residents, it is vital to identify critical routes for
evacuation in the event of a major event. Figure 7 identifies the existing evacuation routes in the
city, which are limited to:
Main Gate at Rolling Hills Road and Palos Verdes Drive North

Hazards of Concern
Existing Conditions Report 17
Crest Gate at Crest Road near Crenshaw Blvd
Eastfield Gate at Eastfield Drive and Palos Verdes Drive East
Crest Road East Gate at the end of Crest Road East
Crest Road East Gate at the end of Crest Road East gate has recently been updated with a motor and
has no guards. This gate is available as an emergency exit to the city during emergencies. The
recently adopted Community Wildfire Protection Plan for the city establishes evacuation strategies
and methodologies for the city, which include:
Using the City’s Block Captains as important coordinators and managers of residents in the 24
City zones 3
Communication goals between the City, emergency responders, Rolling Hills Community
Association, and residents
Details for residents regarding how people get notified during an actual evacuation and the
responsibilities and operations of the Emergency Operations Center
Traffic control responsibilities and levels
Identification of special need residents who may need specific attention and/or assistance
3 The city is divided into 24 zones and each zone has 2-3 block captains to represent the residents within the zone.

Climate Change Vulnerability
In accordance with Senate Bill 379, this section provides a climate change vulnerability assessment
for Rolling Hills, which evaluates the potential impacts of climate change on community assets and
populations. The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report
defines vulnerability as “the propensity or predisposition to be adversely affected.” It adds that
vulnerability “encompasses a variety of concepts and elements including sensitivity or susceptibility
to harm and lack of capacity to cope and adapt” (IPCC, 2013). Understanding the vulnerabilities that
the city may face due to climate change provides a foundation to define future adaptation strategies
for the Safety Element update and other planning efforts in Rolling Hills and the region.
Consistent with the California Adaptation Planning Guide (Cal OES 2020) the assessment is
comprised of the following five elements:
Exposure – the nature and degree to which the community experiences a stress or hazard;
Sensitivity – the aspects of the community (i.e., people, structures, and functions) most affected
by the identified exposures;
Potential Impacts – the nature and degree to which the community is affected by a given
stressor, change, or disturbance;
Adaptive Capacity – the ability to cope with extreme events, to make changes, or to transform
to a greater extent, including the ability to moderate potential damages and to take advantage
of opportunities; and
Vulnerability Scoring – systematic scoring based on potential impacts and adaptive capacity, to
inform major climate vulnerabilities to address adaptation framework strategies.
In addition to City data, Cal-Adapt was used to complete the assessment. Cal-Adapt is an interactive,
online platform developed by the University of California and Berkeley to synthesize climate change
projections and climate impact research for California’s scientists and planners. This assessment
uses Cal-Adapt to study potential future changes in average and extreme temperatures,
precipitation, wildfire, and storms. Cal-Adapt is consistent with State guidance to use the “best
available science” for evaluating climate change vulnerability.
This assessment uses two greenhouse gas (GHG) emissions scenarios included in Cal-Adapts
analysis: Representative Concentration Pathway (RCP) 4.5 and RCP 8.5. RCP 4.5 describes a scenario
in which GHG emissions peak around 2050, decline over the next 30 years and then stabilize by
2100 while RCP 8.5 is the scenario in which GHG emissions continue to rise through the middle of
the century before leveling off around 2100. The climate projections used in this report are from
four models selected by California’s Climate Action Team Research Working Group and the
California Department of Water Resources. These models include:
A warm/dry simulation (HadGEM2-ES)
A cooler/wetter simulation (CNRM-CM5)
An average simulation (CanESM2)

models, for full representation of possible forecasts (MIROC5)4
The average of the model projections is used in this analysis.
Exposure
Climate change is a global phenomenon that has the potential to adversely affect local health,
natural resources, infrastructure, emergency response, and many other facets of society. Projected
changes to climate are dependent on location. According to Cal-Adapt, climate change could lead to
increasing temperatures, temperature extremes, and changes in precipitation patterns in Rolling
Hills. These conditions could lead to exposure associated with extreme heat, drought, wildfires, and
extreme storms in the region. The climate hazards of concern for Rolling Hills addressed in this
analysis are:
Extreme Heat
Storms and Extreme Weather
Drought
Wildfire
Extreme Heat
Figure 8 below shows observed and projected annual average maximum temperature in Rolling
Hills. As shown in Figure 8, average temperatures in the city and region have increased, which is a
trend at both the local scale and the global scale. Compared to 1990, annual average maximum
temperatures in Rolling Hills are expected to rise between 1.8°F and 6.6°F by the end of the century,
depending on the GHG emissions scenario (CEC 2020).
4 There were 10 California GCM models that were ranked from 1-10 by California’s Climate Action Team Research Working Group and the
California Department of Water Resources for different temperature and precipitation factors. The models ranged from the “warm/dry”
model which had all metrics closest to 1 to the “cool/wet” model which had all metrics closest to 10. The MIROC5 displays a pattern of
ranking that is most unlike the other 3 models and therefore, is included to represent the full spread of all 10 model simulations.

Figure 8 Historical and Projected Annual Average Maximum Temperature in Rolling
Hills 5
Extreme heat is a period when temperatures are abnormally high relative to the normal
temperature range. There are generally three types of extreme heat events:
Extreme Heat Days: a day during which the maximum temperature surpasses 98 percent of all
historic high temperatures for the area, using the time between April and October from 1950 to
2005 as the baseline
Warm Nights: a day between April to October when the minimum temperature exceeds 98
percent of all historic minimum daytime temperatures observed between 1950 to 2005
Extreme Heat Waves: a successive series of extreme heat days and warm nights where extreme
temperatures do not abate. While no universally accepted minimum length of time for a
heatwave event exists, Cal-Adapt considers four, successive extreme heat days and warm nights
to be the minimum threshold for an extreme heatwave
Extreme heat events will feel different from region to region since different areas have different
historic high temperatures. For example, an extreme heat day on the coast will feel different than
an extreme heat day in the desert. According to Cal-Adapt, an extreme heat day in Rolling Hills
involves a temperature that exceeds 91.7 ̊F (CEC 2020).
Historically (between 1950 and 2005), Rolling Hills experienced an average four extreme heat days
per year, typically occurring between April and October. As a result of rising average temperatures
and climate change as discussed above, the city is projected to experience between 8 and 14
extreme heat days annually from 2030 to 2099 under medium and high emissions projections (CEC
5 Chart shows annual average maximum temperature for Rolling Hills (Grid Cell 33.78125, -118.34375) under RCP 8.5 (emissions continue

2020). As shown in Figure 9, the number of extreme heat days each year is variable, but overall they
are increasing from historic averages and would continue to increase through the century.
Figure 9 Number of Extreme Heat Days by Year in Rolling Hills 6
Extreme heat waves are defined as four or more consecutive extreme heat days. These events have
been historically infrequent in Rolling Hills, with the historical average being 0.3 heat waves
annually. The city is expected to experience a minor increase in heat wave frequency as the climate
changes. Between 2030 and 2099, the city is projected to experience between 0.4 and 1.1 heat
waves per year (CEC 2020).
Drought
Droughts are somewhat frequent in California, and currently approximately 42 percent of
California’s population are in a drought, or in an abnormally dry area (NIDIS 2020). Changes in
weather patterns resulting in increases in global average temperatures are already causing
decreases in snowpack, which provides as much as a third of California’s water supply (DWR 2019).
According to the U.S. Drought Monitor, Los Angeles County and Rolling Hills are not currently
experiencing drought conditions based on this mapping (National Drought Mitigation Center 2020).
Southern California is not currently considered to be in a drought condition, while other parts of the
State (northern California and the Sierra Nevada mountain range) are experiencing moderate
drought conditions due to lower than average precipitation.
The projected changes in annual precipitation for Rolling Hills are shown in Table 4. Under both the
medium and high GHG emissions scenarios, Rolling Hills is not expected to experience substantial
changes in average precipitation. However, the city would experience increased variability in
precipitation. The city’s minimum annual precipitation would decrease while the maximum annual
precipitation would increase under both emissions scenarios.

While overall precipitation levels are expected to change substantially in the city, a drought may
occur when conditions in areas where water sources are located experience drought conditions,
even though the local region does not. Rolling Hills obtains its water from the Palos Verdes District
of the California Water Service. Water supply from the District to this area is purchased from the
Metropolitan Water District of Southern California (MWD), which imports its water from the
Colorado River and State Water Project from northern California.
Recent research suggests that extended drought occurrence could become more pervasive in future
decades (CEC 2020). An extended drought scenario is predicted for all of California from 2051 to
2070 under a climate model using business as usual conditions. The extended drought scenario is
based on the average annual precipitation over 20 years. This average value equates to 78 percent
of the historic median annual precipitation averaged for the North Coast and Sierra California
Climate Tracker regions. Overall precipitation levels in the city are not expected to be significantly
impacted. However, variability in precipitation and drought conditions in other areas of the state
could impact water supply.
Wildfire
Wildfire hazards to the city are widespread and discussed above under Hazards of Concern.
Wildfires in the city are influenced by a range of factors including droughts, severe winds, wildfire
fuel (i.e. dry vegetation), and previous wildfire suppression activity. Climate change is expected to
exacerbate wildfire risk by creating hotter and drier landscapes, as discussed above under Extreme
Heat, which are more susceptible to burning.
Cal-Adapt provides projections for annual mean hectares burned. This projection only accounts for
areas that could experience wildfire events. Los Angeles County wildfire occurrence is anticipated to
increase under all emissions and population scenarios from historic averages (CEC 2020). In 2020
alone, California has experienced six of the 20 largest fires in modern history and as of the date of
this report, over three million acres of land have burned. These fires arose during extreme fire
weather conditions and record-breaking heat waves across California. The observed frequency of
autumn days with extreme fire weather, which are associated with extreme autumn wildfires, has
more than doubled in California since the early 1980s (Goss et al. 2020). Due to the increases in
factors that contribute to wildfires (variability in precipitation, hotter and dryer landscapes) and
because the city is in a VHFZSZ, it is expected to see an increase in wildfire hazards due to climate
change.
Storms and Extreme Weather
A warming climate is likely to influence the frequency and intensity of storms. Both increased
temperatures and altered precipitation patterns can lead to altered seasons and intense rainstorms
in Rolling Hills. As depicted in Figure 10, there is a high degree of variability in these extreme
546
City of Rolling Hills
Rolling Hills General Plan Safety Element
24
precipitation event projections, with some models projecting little to no change while others project
increased intensity (CEC 2020) These projections further vary depending on the return period7
selected. Increasing intensity of rainstorms could result in more flooding, which could adversely
affect human safety in Rolling Hills. During years of intense levels of precipitation and storms, the
city could also see an increase in the number of landslides or make landslides greater than usual.
Due to the number of landslide hazard zones in the city, as shown in 2, Rolling Hills may see an
increase in landslides due to changes in precipitation from climate change.
Figure 10 Changes in Intensity of Extreme Precipitation Events in Rolling Hills8
Community Sensitivity
As climate change occurs, communities will be affected to varying degrees depending on the
exposure levels as well as how sensitive the communities are to impacts. Virtually all people and
assets in a community will be affected by climate change in some way. However, it is not usually
feasible to assess the vulnerability of every population group or every asset in the community. The
sensitivity of a community depends on the aspects of the community (i.e., specific populations and
assets) most affected by the identified exposures, and how prevalent they are in the community.
As described in the Exposure section above, the most likely primary impacts of climate change that
Rolling Hills may experience include extreme heat, increases in wildfire risk and prevalence, and
drought conditions affecting water supply. This section of the Vulnerability Analysis identifies the

sensitive areas of the Rolling Hills community from the demographic and community facility
information in the Introduction section above and is based on the following categories:
Populations
Infrastructure
Buildings and Facilities
Services
Populations
The vulnerability assessment considers the following population groups that may be
disproportionally harmed by the impacts of climate change in Rolling Hills.
Children: Approximately 6.6 percent of the total population in Rolling Hills are ten years old or
younger.
Persons in poverty: This is identified for people living in households with an income below the
poverty limit, which is $26,200 for a household of four people. There are approximately 26 people in
Rolling Hills who live in poverty, or approximately 1.6 percent of the total population for whom
poverty status can be determined.
Persons with chronic health conditions: These are people who have a long-term or permanent
health condition that can create regular challenges in their day-to-day lives. These health problems
include obesity, cancer, heart disease, and arthritis. In addition, those with any kind of disability,
including mobility challenges, hearing, or vision impairments, behavioral disabilities, and challenges
living independently or taking care of themselves. Approximately 11.5 percent of the population
have identified having a disability.
Renters: These are people who live in homes that they (or the head of their household) do not own.
Approximately 24 housing units, or 4 percent of the housing units in Rolling Hills, are renter-
occupied.
Older adults: These are persons 65 years or older are more at risk for climate change impacts,
especially those living alone. 28 percent of the population of Rolling Hills are over 65 years, and 15
percent of those over 65 years live alone.
Limited English proficiency: Approximately three percent of households have identified being
limited English-speaking. Of those, a majority spoke Asian and Pacific Island languages and Spanish.
Infrastructure
The vulnerability assessment considers the following infrastructure in the city that was identified as
bring sensitive to climate change impacts.
Access Roads: These roadways are one of a few, or the only, ways in and out of some communities
or neighborhoods. The single or limited number of entry and exit points does not make the road
itself more vulnerable than other roads, but loss of these roadways can effectively cut off large
numbers of people from other areas in the Palos Verdes Peninsula and the rest of Los Angeles
County. Portuguese Bend Road and Crest Road are the primary access roads into and out of the city.
Bridle Trails: Throughout the community are over 25 miles of trails available to city residents and
non-city residents who obtain permits. The trails are maintained by the Rolling Hills Community
Association and located primarily in canyon areas.

Electrical Substations: Electrical substations are facilities that convert electricity from one voltage to
another, making it suitable for long-distance transmission or for use by homes, businesses, and
other electrical customers. There are no electrical substations located within city limits, but three
are located near the city in Rancho Palos Verdes and owned/operated by Southern California
Edison.
Electrical Utility Lines: These lines transmit and deliver electricity from Southern California Edison to
the city. The city has both underground and overhead electric utility lines.
Natural Gas Transmission Pipelines: Natural gas pipelines carry large volumes of natural gas
between communities. There are no transmissions lines in the city. One transmission line ends at
the intersection of Rolling Hills Road and Palos Verdes Drive, adjacent to city limits.
Water Reservoirs and System: The system that stores and supplies drinking water for residents.
Palos Verdes Water District of the California Water Service supplies water to Rolling Hills. There are
two California Water Service water reservoirs within the city limits.
Building and Facilities
Residential Structures: Residential structures in Rolling Hills consist of single-family dwellings and
are the main type of building in the city.
Community Facilities and Government Buildings: Community and government facilities are public
properties and are important to the residents as well as the operation of the city. Rolling Hills is a
private community. Therefore, community and government facilities are available only to its
residents, which are the Rolling Hills Community Association and City Hall.
Community Parks: Storm Hill is an open space area owned by the City which is utilized for
equestrian purposes. The City also has two equestrian rings and tennis courts.
Schools: Rancho Del Mar High School is the only school in the city
Public Safety Facilities: Public safety facilities include sheriff and fire buildings. Los Angeles County
Fire Station 56 is located within the city. The Lomita Station of the Los Angeles County Sheriff serves
the city but is not located within the city limits.
Services
Public Safety Response: Public safety services are provided by law enforcement and fire agencies.
These agencies include the Los Angeles County Sheriff and Fire Departments.
Water Services: These services involve treating and transporting water to be used by customers and
transporting and treating wastewater so it can be safely released into the environment. California
Water Service provides drinking water to the city.
Energy delivery: Energy services in Rolling Hills include electricity and natural gas delivered through
utility lines from Southern California Edison and Southern California Gas Company.
Potential Impacts
Impact vulnerability is the nature and degree to which the community is affected by a given
stressor, change, or disturbance. As climate change continues to progress, increased stress to
vulnerable community populations, infrastructure, building and facilities, and services are expected.
As described in the Exposure section above, the most likely primary impacts of climate change
549
Climate Change Vulnerability
Existing Conditions Report 27
Rolling Hills may experience include extreme heat, wildfire, and drought conditions impacting water
supply. The vulnerability of Rolling Hills to the primary exposures of climate change is discussed
below. The vulnerability scores discussed in the Vulnerability Scoring section are based on the
potential impact analysis below. Each of the vulnerable areas in the city were given a low, medium,
or high vulnerability to the potential impacts, based off the descriptions in the Vulnerability Scoring
section.
Temperature and Extreme Heat
As describe in the Exposure section above, Rolling Hills may experience a variety of impacts from
climate change, which include an increase of average annual maximum temperature between 1.8°F
and 6.6°F by the end of the century (CEC 2020) This increase in temperature may result in changes
in seasonal patterns, an increase in heat waves, drought, and potentially increased storm frequency
and intensity. Rolling Hills is expected to experience between 8 and 14 extreme heat days annually.
Overall quality of life in the city would be impacted during extreme heat events as outdoor activities
would be limited and overall comfort reduced.
The potential direct and indirect impacts to community populations, infrastructure, building and
facilities, and services are described below.
Populations
The vulnerable populations discussed above that are most at risk to extreme heat impacts from
climate change are older adults, individuals with chronic conditions such as heart and lung disease,
diabetes, and mental illnesses, children, and those who are economically disadvantaged.
The primary vulnerable population to temperature increases and extreme heat in Rolling Hills is
older adults, as 28 percent of the city’s population is over 65 years. Older adults do not adjust as
well as young people to sudden changes in temperature and are more likely to have medical
conditions that can worsen with extreme heat (CDC 2017a). Older adults who are living along are
even more at risk as the actions necessary to mitigation extreme heat are more difficult alone.
Getting water, changing clothes, showering, or turning on the air conditioner may be more difficult
for older adults with physical disabilities and do not have a living partner to assist them. Children are
also at risk to extreme heat impacts, especially those under the age of four, due to their less-
developed physiology, immune system, and dependence on others (CDC 2019).
Extreme heat can be highly dangerous to persons with chronic health conditions, because very high
temperatures can exacerbate diabetes, cardiovascular conditions, respiratory ailments, and other
diseases. Some of these people have weakened immune systems which can make them more likely
to contract illnesses and vulnerable to human health hazards. In addition, they may be taking
medications that make the effects of extreme heat worse (CDC 2017b).
While there are not many households in poverty in the city, those who are have limited financial
resources to upgrade their homes and use air conditioning to better resist extreme heat.
Each of the vulnerable populations has a high potential impact from extreme heat.
Infrastructure
Extreme heat and temperature increase due to climate change would not directly impact
infrastructure in Rolling Hills. Indirect impacts on electrical substations and utility lines could occur
from increased use of the system from running air conditioners, leading to power outages in the
550
City of Rolling Hills
Rolling Hills General Plan Safety Element
28
city. In addition, indirect impacts to the water system through increased evaporation or water use
could occur. These infrastructure facilities would have a medium potential impact from extreme
heat.
Building and Facilities
Extreme heat and temperature increase due to climate change
would not directly affect buildings or facilities in Rolling Hills. Extreme heat and temperature
increases could impact the ability for residents to enjoy community park facilities. In addition,
extreme heat could create wildfire conditions which could indirectly impact all buildings and
facilities within the city. Overall, there is a low potential impact from extreme heat to City buildings
and facilities.
Services
The important services discussed above that are most at risk to extreme heat impacts from climate
change are water services and energy delivery.
High temperatures would contribute to a reduced water supply. For instance, higher temperatures
will melt the Sierra snowpack earlier and drive the snowline higher. In addition to a reduction in
precipitation falling as snow, higher temperatures would result in less snowpack to supply water to
California users (CNRA 2009). Increased temperatures could therefore result in decreased potable
water supply for the city which relies on imported water from the State Water Project and Colorado
River water (Cal Water 2016). Therefore, there is a medium potential impact for high temperatures
and drought on the city.
Long periods of intense heat may result in increased use of electricity for home cooling purposes
that could tax the overall electrical system and result in electricity restrictions or blackouts. During
extreme heat events in August 2020, California had its first rolling blackouts since 2001. Therefore,
the city will experience greater potential for power outages due to climate change and has a
medium potential impact.
Storms/Extreme Weather and Drought
As mentioned in the Exposure section above, the storm and extreme weather projections for Rolling
Hills show variability, with some models projecting little to no change while others project increased
intensity. This could result in impacts to community populations, infrastructure, building and
facilities, and services, particularly related to temporary flooding and landslides which can be
triggered from intense rainfall events. The city currently has a less than 0.2 percent annual chance
to be inundated by flood waters as a result of a storm event (FEMA 2008). Increases in intense
precipitation could result in slope failures in landslide prone areas shown in Figure 2, including the
existing Flying Triangle Landslide area.
As discussed in the Exposure section above, Rolling Hills is not expected to experience substantial
changes in average precipitation. However, the city receives its water from the Colorado River and
State Water Project from northern California, and extended drought scenario is predicted for these
areas, which equates to 78 percent of the historic median annual precipitation. Therefore, areas
that supply water to Rolling Hills and other jurisdictions are expected to see a 22 percent reduction
of their water supply, which could reduce the amount of potable water available for delivery to the
city.
551
Climate Change Vulnerability
Existing Conditions Report 29
Populations
The city’s older adults and those with chronic health conditions are the populations in Rolling Hills
that are more at risk of injury and or death resulting from minor floods or fallen trees created by
more intense storms induced by climate change. Indirect impacts to these populations from impacts
to the transportation system could include reduced access to emergency response and health
centers for those who need consistent medical care. There is a medium potential for impacts to
these vulnerable populations.
Infrastructure
Critical infrastructure most at risk in Rolling Hills to minor flooding impacts and landslides from
increased storms would be access roads, bridle trails, electrical utility lines, and water systems.
Because Portuguese Bend Road and Crest Road are critical for access to and evacuation from the
city, any damage or closure can effectively isolate areas of the city, potentially creating severe
health and safety risks. Bridle trails are predominantly located in canyon areas, which would be
more susceptible to flooding and landslides. Landslides could impact utilities, as seen in the existing
Flying Triangle Landslide area, which has moved utility lines above ground in certain areas due to
the continuous movement of the earth in this area. Due to the limited accessibility of the city, there
is a medium potential impact for access roads and bridle trails and a low potential impact for the
remaining vulnerable infrastructure.
Building and Facilities
Buildings and facilities most at risk from impacts of more intense storms would be residential
structures and community parks. The proper functioning residential septic systems could be
impacted by more intense rainfall and minor flooding. In addition, landslides could be triggered as
indirect impacts from more intense storms and rainfall. Residential structures located in landslide
hazard areas shown in Figure 2 could be impacted. In addition, the Storm Hill open space area is an
important facility in the city and is also located in a landslide area. Due to the variability in weather
projections, there is a low potential impact for buildings and facilities.
Services
Increased storm intensity and drought conditions from climate change could impact public safety
response, energy delivery and water services in the city. Emergency response systems could be
impacted from flooding or landslides within or outside of city limits, which could restrict the ability
for emergency response to access the city and impact response times.
More intense storms could adversely affect electricity delivery from Southern California Edison from
power outages caused by downed electrical utility lines from wind of landslide events. In addition,
water service from the California Water Service Palos Verdes District could be affected by increased
drought conditions throughout the state. There is a medium potential impact for buildings and
facilities.
Wildfire
Wildfires in Los Angeles County are projected to increase under all emissions and population
scenarios. As discussed in the Exposure section above, wildfire hazards to the city are widespread
and wildfire conditions are expected to be exacerbated by a range of factors including droughts,
552
City of Rolling Hills
Rolling Hills General Plan Safety Element
30
more severe winds, wildfire fuel (i.e., dry vegetation), and hotter and drier landscapes from
increased temperatures and extreme heat.
Populations
The vulnerable populations discussed above that are most at risk to increases in wildfire from
climate change are older adults, persons in poverty, and persons with chronic health conditions.
Older adults are almost three times more likely to die in a fire than the overall population (USFA
2017), and typically have increased mobility issues or mental health. Therefore, older adults,
especially those in the city living alone, have more difficulties evacuating to safe areas when there is
a need. Those in Rolling Hills with limited financial resources are more unlikely to retrofit their
homes to better resist climate-related hazards such as wildfires.
In addition to direct impacts, indirect impacts such as poor air quality also creates public health
hazards to the city. Recent California wildfires in August and September 2020 had areas of California
recording the worst air quality in the world and highlighted the hazards of secondary impacts from
wildfires, which could impact the city from fires throughout the State. Older adults and individuals
with chronic health conditions are likely to be impacted most by these secondary impacts. Also,
those with limited finances or without air conditioning would be impacted by secondary smoke
impacts that occur during local and regional wildfires. There is a high potential for wildfire impacts
on the vulnerable populations.
Infrastructure
All city infrastructure is located in a VHFHSZ. The critical infrastructure most at risk to increased
wildfire impacts would be access roads, bridle trails, above ground electrical utility lines, and water
systems. Portuguese Bend Road and Crest Road are critical for access to and evacuation from many
areas of the city. Wildfires may not significantly damage the infrastructure, but they could result in
closure or the inability to travel on them during wildfire events, which can isolate areas of the city
and create severe health and safety risks. There is a high potential for impacts to access roads from
wildfires.
Wildfires are unlikely to substantially damage trails directly, but they can force widespread trail
closures which are an important asset to the community. Above ground electrical lines are also at
risk from wildfires and could impact electricity services to residents in Rolling Hills. Water systems
could be directly affected by wildfires in addition to indirect impacts from water use from
firefighting activities and peak load water supply in remote portions of the city. There is a medium
potential for impact to these infrastructures.
Building and Facilities
As discussed under Hazards of Concern section, all of Rolling Hills is designated a VHFHSZ.
Therefore, all buildings and facilities within the city are at risk of increased wildfires caused by
climate change. The greatest potential impact of life and well-being would be to residential
structures, which are the primary structures in the city. In addition, impacts to Rolling Hills
Community Association and City Hall structures would impact community functions and government
services. There is a high potential for impact to buildings and facilities from wildfire.
553
Climate Change Vulnerability
Existing Conditions Report 31
Services
Energy delivery, specifically electricity delivery, could be impacted from increased wildfires. Direct
impacts to Southern California Edison electricity transmission infrastructure could impact power in
the city. In addition, utility companies have begun shutting off power to areas to avoid wildfires
during times when weather creates high wildfire risk. In addition, public safety services could be
strained during wildfire events, which are expected to increase. There is a medium potential for
impacts to services in the city from wildfire.
Adaptive Capacity
Adaptive capacity is the current ability to cope with climate change impacts to community
populations and assets (Cal OES 2020). Specifically, adaptative capacity is the ability to mitigate the
potential impacts and damages or take advantage of the opportunities from climate change. Many
communities have adaptive capacity in the form of policies, plans, programs, or institutions. Rolling
Hills has actively taken steps to increase the city’s adaptive capacity, which include preparing a
community wildfire protection plan, hazard mitigation plan, undergrounding utility lines, and
adopting strict new building standards. Table 5 lists various guiding documents, projects, plans, and
policies that have an underlying emphasis on adaptive capacity in the city.

Rolling Hills has a number of plans and policies specific to wildfire hazards. The city’s recently
adopted the Community Wildfire Protection Plan that includes fire mitigation strategies and
evacuations strategies specific for the city. In addition, the Hazard Mitigation Plan provides an
analysis of historical hazards, a local hazard assessment, hazard impacts on the community, and
recommended mitigation strategies. The City requires the undergrounding of utility lines with
specific home upgrades and has a reimbursement program for utility pole replacement. In addition,
building code requirements for development within VHFHSZ, such as Class A roofing, would help
reduce wildfire impacts to structures in the city.

The Rolling Hills Building and Zoning Codes include controls on development on steep slopes and
canyon bottoms. In addition, development requires proof of stability of the property through
geotechnical reports and only a percentage of each lot can be disturbed.
The Palos Verdes Water District’s Urban Water Management Plan (UWMP) provides water supply
and demand projections and includes a climate change analysis. The 2015 UWMP projected that
water supply reductions to the District due to climate change would be small for through the end of
the century. In addition, the UWMP includes a water shortage contingency plan and demand
reduction measures in the event water supply to the District is impacts from drought due to climate
change.
In addition, the city’s population has a high degree of adaptive capacity due to the high levels of
home ownership, low poverty levels, and high average income levels. These characteristics improve
resident’s ability to upgrade their homes and come back from potential impacts to their property
from wildfire and extreme storm events.
Vulnerability Scoring
Vulnerability scores are based on the combination of potential impacts from climate hazards and
adaptive capacity in order to identify the climate vulnerabilities in the city to address with additional
adaptation strategies. A vulnerability score was determined for each sensitivity area based on the
potential impacts and adaptive capacity from climate change in the city. Vulnerability was accessed
on a scale from 1 to 5:
V-1: Minimal Vulnerability
V-2: Low Vulnerability
V-3: Moderate Vulnerability
V-4: High
V-5: Severe
Cal OES recommended the following scoring rubric to determine the vulnerability score for the
potential impacts and adaptive capacity.
Low Potential Impact: Impact is unlikely based on projected exposure; would
result in minor consequences to public health, safety, and/or other metrics of concern
Medium Potential Impact: Impact is somewhat likely based on projected exposure; would
result in some consequences to public health, safety, and/or other metrics of concern
High Potential Impact: Impact is highly likely based on projected exposure; would result in
substantial consequences to public health, safety, and/or other metrics of concern
Low Adaptive Capacity: The population or asset lacks capacity to manage climate impact; major
changes would be required
Medium Adaptive Capacity: The population or asset has some capacity to manage climate
impact; some changes would be required
High Adaptive Capacity: The population or asset has high capacity to manage climate impact;
minimal to no changes are required
Table 6 shows how the final vulnerability score was determined. To summarize, potential impacts
from climate change that are highly likely to occur in the city based on projected exposure would
555
Climate Change Vulnerability
Existing Conditions Report 33
create a high vulnerability score. However, if the city has a high adaptive capacity to manage the
impact, then the overall vulnerability score would be reduced.
Table 6 Vulnerability Score Matrix Potential Impacts High V-3 V-4 V-5
Medium V-2 V-3 V-4
Low V-1 V-2 V-3
High Medium Low
Adaptive Capacity
The vulnerability scoring for the identified population and assets for each climate impact is included
below in Table 7 and based on Cal OES California Adaptation Planning Guide. For those populations
and assets that are not anticipated to be impacted directly or indirectly from the identified climate
impacts, no vulnerabilty score or color is provided. For example, drought impacts on children were
determined to not be a threat in Rolling Hills.
For the purposes of this vulnerability assessment, a score of V-4 or V-5 is considered significant.
Populations and assets that score at least a V-4 for one or more exposures are considered
substantially vulnerable. As shown in Table 7, the potential impacts from climate change the city’s
population and assets are most vulnerable to are wildfire, extreme heat, and landslides. Vulnerable
populations such as older adults, residents with chronic health conditions, and those with financial
trouble are most at risk to extreme heat and wildfire impacts and are substantially vulnerable to
climate change impacts in the city. Access roads and residential structures are also the most
vulnerable to wildfire and landslide impacts from climate change. Overall, climate change impacts
on wildfire are the greatest potential impact to the city. While the City has adopted a significant
number of adaptation strategies related to wildfire impacts, because they were recently adopted
and some of the strategies were included as recommendations, it will be important to determine
and monitor if implementation is occurring and which recommendations should be included in the
Safety Element update.
This vulnerability assessment and the results in Table 7 will be used to identify specific policies and
implementable strategies for adapting to climate change in the Safety Element, thus making the
Rolling Hills community more resilient.

Summary of Issues and Opportunities
Existing hazards of concern in the city that should be a major focus of the Safety Element update
include landslide and wildfire hazards. In addition, emergency response and evacuation should be a
focus due to the city’s accessibility issues. Climate change is expected to increase potential hazards
the city experiences. From the vulnerability analysis, the city is most vulnerable to wildfire impacts,
extreme heat, and landslides impacts from climate change.
Hazards of Concern and Community Sensitivity
While there are a number of hazards that could impacts the city, the following are hazards of
concern that pose the greatest challenge to the city.
Wildfire
The greatest hazard of concern for the city is wildfire as the entire city limits are within a VHFHSZ
and the city contains many remote areas and limited evacuation routes. Some existing residential
and accessory structures are not built to current standards that apply to VHFHSZ and as a result
many of these structures may require mitigation and retrofit to reduce this potential threat. The
area’s most vulnerable to wildfire impacts include older adults, persons with chronic health
conditions, residential structures, government and community buildings, and access roads.
Landslides
Landslides are also a major concern for the city, whether they are earthquake induced, induced
from high precipitation events, or occur due to the underlying soil conditions. Existing landslides are
impacting the southern portion of the city. Climate change has the potential to create more
landslide events if Rolling Hills experiences more intense storms and precipitation events. The area’s
most vulnerable to landslide impacts include access roads, residential structures, and community
parks.
Extreme Heat
The city is expected to see increases in the number and length of extreme heat days and events due
to climate change, which could impact vulnerable people in the city and lead to increased wildfire
risks. The area’s most vulnerable to extreme heat impacts from climate change include older adults,
persons with chronic health conditions, and the energy system.
Opportunities
The need to further analyze evacuation routes and access is one of the most recent changes in
Safety Element requirements. These new requirements focus on the identification of areas where
routes are lacking or inadequate. A key opportunity for the Safety Element update is address
specific evacuation needs.
The City has recently adopted a number of planning documents, such as the Hazard Mitigation Plan
and Community Wildfire Protection Plan, that seek to reduce the risk of hazards in the city. Many of
the strategies included in these documents are recommendations and are used for educational
purposes. An opportunity for the Safety Element update would be to include the recommendations
559
Summary of Issues and Opportunities
Existing Conditions Report 37
as implementation tools for the Safety Element and to conduct outreach with the community to
determine if community preparedness is occurring.
The California Legislature recently adopted Senate Bill 182 (SB 182) and is awaiting Governor
approval. SB 182 would require the Safety Element to include a comprehensive retrofit strategy as
necessary to reduce the risk of property loss and damage during wildfires. Additionally, in order to
reduce development pressures in the VHFHSZ through the Regional Housing Needs Allocation
process, SB 182 requires a lower proportion of state housing allocation to jurisdictions that meet
specified conditions. The City should monitor and incorporate these elements as necessary.

Consult Request
Good morning John,
If the Gabrielino Tongva Indians of California Tribal Council wish to consult under SB 18 or AB 52
concerning these proposed Element Updates please contact John Signo, AICP, at the City of
Rolling Hills (jsigno@cityofrh.net - City Of Rolling Hills – City Hall 2; Portuguese Bend Road,
Rolling Hills CA 90274; O: 310.377.1521 | F: 310.377.7288). Alternatively, feel free to contact
either Kellie or myself and we will coordinate with the City.
Please let Kellie or me know if you have any questions or concerns, and we will be happy to
help.
Thank you,
Richard
We are in receipt of your 21330 City of Rolling Hills Housing & Safety Element Project SB 18/AB 52
Consult Request. Thank you for reaching out.
After conferring with Tribal Chair Dorame (the Most Likely Descendent), this property is highly culturally
sensitive to the Gabrielino Tongva Indians of California (GTIOC) as it resides near one of our villages. The
Gabrielino Tongva Indians of California request an AB52 and SB18 consultation for this project.
There are a minimum of 7 identified sties near the project area; LAN 110, LAN 191, LAN 276, LAN277,
LAN278, LAN 279, LAN 280 (LAN 275 borders your project area).
The concern with all of these sites is that they are significant evidence of the existence of a village site
and the area may still yield evidence of buried deposits. Artifacts unearthed in previous projects
included obsidian projectiles, sandstone bowls, cog stones and more importantly, human remains.
The Gabrielino Tongva Indians of California tribe is deeply concerned with any ground disturbances in
your project area and this project will need a monitor from the Gabrielino Tongva Indians of California
for only ground disturbances.
Attached are our treatment plans for your project site.
Please let us know what your next steps are and how we may assist you.
Take good care and happy new year,
Christina

Subject: 21330 City of Rolling Hills Housing & Safety Element Project SB 18/AB 52
Consult Request
Dear Christina Conley,
The City of Rolling Hills (City) is commencing its Senate Bill (SB) 18 and
Assembly Bill (AB) 52 consultation processes for the Housing and Safety Element
Updates Project (Project). Pursuant to Government Codes §65352.3 and §65352.4
SB 18 require local governments to consult with California Native American
tribes identified by the Native American Heritage Commission (NAHC) for the
purpose of avoiding, protecting, and/or mitigating impacts to cultural places
when creating or amending General Plans, Specific Plans and Community Plans.
Additionally, AB 52 (Public Resources Codes §21080.3.1 and §21080.3.2) requires
public agencies to consult with California Native American tribes identified by
the NAHC for the purpose of avoiding, protecting, and/or mitigating impacts to
tribal cultural resources (TCRs) as defined, for California Environmental Quality
Act (CEQA) projects. This letter is being provided to you because your Tribe, the
Gabrielino Tongva Indians of California Tribal Council, was listed on the NAHC
directory as an individual or group who may have additional knowledge
pertaining to tribal cultural resources within this geographic area.
The Project consists of a Housing Element Update of the City of Rolling Hills
General Plan and an update to the City’s Safety Element to address various
natural and human-caused hazards the City has dealt with including
earthquakes, wildfires, droughts, and land movement.
569
4
The Housing Element and Safety Element Updates are policy updates only, and
no specific developments are proposed at this time. A description of each of the
updates is provided below.
Housing Element Update
The City’s Housing Element serves as an integrated part of the General Plan, and
is subject to detailed statutory requirements, including a requirement to be
updated every eight years, and mandatory review by the California Department
of Housing and Community Development (HCD). The City is currently adopting
their 6thcycle Housing Element Update (HEU). The City’s Regional Housing
Needs Allocation (RHNA) for this 6th cycle, is 45 units which the City determined
can be met with existing approved developments, the underutilized Rancho Del
Mar school site, and Accessory Dwelling Units (ADUs). Therefore, the HEU, is a
policy document; no actual development nor rezoning of parcels is included as
part of the approval.
Safety Element Update
The Safety Element Update (SEU) provides the City goals, policies, and actions to
minimize the hazards to safety in and around the City. The SEU evaluates
natural and human-caused safety hazards that affect existing and future
development and provides guidelines for protecting the community from harm.
The SEU describes existing and potential future conditions and sets policies for
improved public safety. The goal of the SEU is to reduce the risk of injury, death,
property loss, and other hardships to acceptable levels.
As part of the proposed updates the City has requested a Sacred Lands File (SLF)
search by the NAHC. The result of the SLF search conducted through the NAHC
was negative for the Project site. The City of Rolling Hills is a rural, equestrian
residential community, consisting entirely of large lot residential parcels of one
acre or more (Figure 1). The community encompasses 2.99 square miles of land
(approximately 1,910 acres) on the Palos Verdes Peninsula in the County of Los
Angeles.
Please consider this letter notification and preliminary Project information as the
initiation of the SB 18 and AB 52 requests for consultation. Pursuant to PRC
21080.3.1(d), the Gabrielino Tongva Indians of California Tribal Council have 30
days upon receipt of this letter to provide a request for AB 52 consultation on the
Project. Pursuant to GC 65352.3, the Gabrielino Tongva Indians of California
Tribal Council have 90 days upon receipt of this letter to provide a request for SB
18 consultation. Due to the abbreviated timeline regarding funding opportunities
for this affordable housing Project, we respectfully ask that requests for SB 18
consultation also be provided within 45 days, if practicable.

Your comments are important to the City of Rolling Hills. If the Gabrielino Tongva
Indians of California Tribal Council have any concerns regarding the proposed Project as
it relates to Native American issues or interests, or has any information regarding sacred
sites in the vicinity of the proposed Project that may help avoid impacts to those sites,

City of Rolling Hills Safety Element Update
Rolling Hills, Los Angeles County, California
Chambers Group, Inc. 1
21330
BACKGROUND
An Initial Study Negative Declaration (IS/ND) was prepared for both the Housing Element Update and
Safety Element Update for the City of Rolling Hills. On January 13, 2022, the City of Rolling Hills circulated
a Draft IS/ND to public agencies and the general public. In accordance with the California Environmental
Quality Act (CEQA) Section 21091 and State CEQA Guidelines Section 15073, a 30-day public review period
for the Draft IS/ND was provided from January 13, 2022 to February 12, 2022.
The City has not yet received comments back from the California Department of Housing and Community
Development (HCD) on the Housing Element Update, and does not wish to approve the Housing Element
Update without such comments. The City has removed the Housing Element Update from the Project (and
associated IS/ND). The changes to the IS/ND do not affect the overall conclusions of the environmental
document; the analysis of the Safety Element Update is wholly bounded by the analysis and findings in
the previously circulated Draft IS/ND. This errata has been prepared to clarify and modify the Project.
PURPOSE OF ERRATA
The CEQA Guidelines Section 15073.5 requires that a lead agency recirculate a negative declaration “when
the document must be substantially revised.” A “substantial revision” includes: (1) identification of a new,
avoidable significant effect requiring mitigation measures or project revisions, and/or (2) determination
that proposed mitigation measures or project revisions will not reduce potential effects to less than
significance and new measures and revisions must be required.
The CEQA Guidelines specify situations in which recirculation of a negative declaration is not required.
This includes, but is not limited to, situations in which “new information is added to the negative
declaration which merely clarifies, amplifies, or makes insignificant modifications to the negative
declaration.” This errata addresses technical changes on the IS/ND. None of the clarifications and
insignificant modifications are considered “substantial revisions” because they do not show that the
Project has a new, avoidable significant effect and the City has determined that Project revisions are not
required to reduce potential effects to less than significant. None of the clarifications and modifications
substantially modify the analysis or conclusions of the IS/ND, but they instead merely remove discussion
of the Housing Element Update. As noted above, the clarified and modified Project would continue to
result in no impacts without any need for mitigation. The overall findings and analysis do not change.
Recirculation of the negative declaration is therefore not required in accordance with CEQA Guidelines
Section 15073.5.
Changes to the text are noted with underline (for added text) or strikeout type (for deleted text). The full
modified Negative Declaration is provided below.

CHAPTER 2.0 – PROJECT DESCRIPTION AND SETTING
2.1 INTRODUCTION
The City of Rolling Hills (City) is a rural, equestrian residential community, consisting entirely of large lot
residential parcels of one acre or more. The community encompasses 2.99 square miles of land
(approximately 1,910 acres) on the Palos Verdes Peninsula in the County of Los Angeles (Figure 2.2-1:
Project Location). The City’s General Plan was drafted and adopted in 1990. The City is proposing updates
to both the Housing Element and Safety Element of the General Plan, two one of the six elements. A
description of each of the updates is provided below.
2.1.1 Housing Element Update
The 2020 Census indicates a citywide population of 1,739 residents, making the City the fifth smallest of
the 88 cities in Los Angeles County. The City is proposing to adopt the Housing Element for the Sixth Cycle
planning period from 2021 to 2029. The proposed Housing Element Update (HEU) is attached hereto as
Appendix A. The Housing Element, which is part of the City’s General Plan, is a policy document designed
to provide the City a coordinated and comprehensive strategy for promoting the production of safe,
decent, and affordable housing within the community. California Government Code Section 65580 states
the following regarding the importance of creating housing elements:
The availability of housing is of vital statewide importance, and the early attainment of decent
housing and a suitable living environment for every Californian, including farmworkers, is a priority
of the highest order.
Per State law, the housing element has two main purposes:
1. To provide an assessment of both current and future housing needs and constraints in meeting
these needs; and
2. To provide a strategy that establishes housing goals, policies, and programs.
2.1.2 Safety Element Update
The Safety Element Update (SEU), (Appendix AB) provides the City’s goals, policies, and actions to
minimize the hazards to safety in and around the City. The SEU evaluates natural and human-caused safety
hazards that affect existing and future development and provides guidelines for protecting the community
from harm. The SEU describes existing and potential future conditions and sets policies for improved
public safety. The goal of the SEU is to reduce the risk of injury, death, property loss, and other hardships
to acceptable levels. A detailed description of the update is provided below.
2.2 SAFETY ELEMENT UPDATE
2.2.1 Background
Throughout its history as a city, the City has dealt with various natural hazards, including earthquakes,
wildfires, droughts, and land movement. Developments in high landslide areas have occurred, and the
City has been identified as being located in a Very High Fire Hazard Severity Zone (VHFHSZ). As a result,
579
City of Rolling Hills 2021-2029 Housing Element Update and Safety Element Update
Rolling Hills, Los Angeles County, California
Chambers Group, Inc.
21330
3
the City has amended its building and safety codes to include special requirements such as fire-rated
materials for new construction and a requirement for geotechnical studies in active fault zones.
2.2.2 Safety Element Overview
The City’s SEU addresses hazards of concern relevant to the City and provides goals, policies, and
implementation measures to minimize these hazards. Figures 2 through 6 of the SEU show exact locations
of these hazards, which are described in the following paragraphs.
Landslide Hazards
Much of the existing development in the City is located on hilly terrain and has a greater potential to
experience landslide hazards. Many of the canyons in the City exhibit steep slopes with little vegetation
coverage, leaving them susceptible to slope failure.
Seismic Hazards
The City is in a seismically active region of southern California. The last major earthquake in the Los
Angeles area was the 5.1 magnitude La Habra earthquake in 2014. The City is within 50 miles of the
Whittier fault, Newport-Inglewood fault, Palos Verdes fault, Malibu Coast fault, Cabrillo fault, Santa
Monica fault, and Redondo Canyon fault. Analysis of seismic data from the region indicates that the
Whittier and Newport-Inglewood faults may generate a maximum credible earthquake of magnitude 7.2
and 7.4, respectively. The earthquake shaking potential for the City is moderate. A number of seismically
active faults are present in the City and region; however, none are active faults with the potential for
ground rupture, defined by the Alquist-Priolo Earthquake Fault Zoning Act and delineated by California
Geological Survey. The City has a low potential for liquefaction, as the subsurface soils generally lack
saturated alluvial deposits and thick, granular soils.
Flooding
The City is not in any immediate risk from flooding caused by overflowing water bodies or heavy rains.
However, runoff and minor flooding pose a risk if drainage systems fail along canyon bottoms, where
natural drainage leads. Due to dam locations and the topography of the area, the inundation areas do not
enter or affect any portion of the City.
Wildland and Urban Fires
The entire City is designated a Very High Fire Hazard Severity Zone (VHFHSZ) by the California Department
of Forestry and Fire Protection (CAL FIRE 2011). The terrain in the City is composed of several large and
steep canyons that limit and challenge vegetation management and present conditions where a fire can
quickly travels up and downslope to nearby homes. Due to the rural nature and large residential lots,
many homes are surrounded by more substantial vegetation and dense brush than in more suburban
settings.

Hazardous Materials
According to the Department of Substances Control (DTSC 2021), no hazardous waste sites or facilities are
present in the City. The City and surrounding area do not contain heavy industrial uses that would create
a hazardous material risk in the event of a spill, release, or natural disaster.
2.2.3 Goals and Policies
Similar to the HEU, The SEU is a policy document; no actual development or rezoning of parcels is included
as part of the approval. In addition to goals and policies, the SEU includes implementation measures for
action items for the City. The goals, policies, and implementation for hazard mitigation, community
communication, and climate change adaptation and resilience are listed at the end of the SEU.

2.3 HOUSING ELEMENT UPDATE
2.3.1 Background
The City’s Housing Element serves as an integrated part of the General Plan and is subject to detailed
statutory requirements, including a requirement to be updated every eight years and mandatory review
by the California Department of Housing and Community Development (HCD). This action includes the
adoption of the HEU, which is a policy document; no actual development or rezoning of parcels is included
as part of the HEU. The proposed HEU is an eight-year plan for the 2021-2029 period.
Pursuant to Government Code Section 65583, a housing element is required to consist of an identification
and analysis of existing and projected housing needs and a statement of goals, policies, quantified
objectives, financial resources, and scheduled programs for the preservation, improvement, and
development of housing. Specifically, a housing element is required to contain the following:
An assessment of housing needs and an inventory of resources and constraints relevant to
meeting those needs (Government Code Section 65583[a])
A statement of the community’s goals, quantified objectives, and policies relative to the
maintenance, preservation, improvement, and development of housing (Government Code
Section 65583[a])
A program that sets forth a schedule of actions during the planning period, each with a timeline
for implementation of the policies and to achieve the goals and objectives of the housing element
(Government Code Section 65583[c])
Southern California Association of Governments (SCAG) began the Regional Housing Needs Allocation
(RHNA) process for the Sixth Cycle in Fall 2019, exploring different methodologies for allocating the
regional need to individual cities and counties. As other cities began work on their Sixth Cycle Elements,
the City was required to first amend its Fifth Cycle Element to accommodate both the current (Fifth) cycle
and the prior (Fourth) cycle RHNA allocations due to its noncompliant status. The combined RHNA for the
two cycles was 28 units. Accommodating this need meant that City was also required to amend its General
Plan and zoning to create additional housing capacity.
The Fifth Cycle Housing Element was adopted June 14, 2021. The Fifth Cycle Housing Element was
submitted to HCD and found to be in compliance on July 7, 2021. As a result of the compliance
determination, the City does not have to carry over its prior allocation and may plan only for the 45 units
identified in the Sixth Cycle RHNA.
2.3.2 Housing Element Overview
The City’s HEU consists of the following major components:
A review of the prior housing element and goals that were accomplished (Section 2, Evaluation of
Prior Housing Element)
583
City of Rolling Hills 2021-2029 Housing Element Update and Safety Element Update
Rolling Hills, Los Angeles County, California
Chambers Group, Inc.
21330

An assessment of housing needs in the City including profile and analysis of the City’s
demographics, housing characteristics, and existing and future housing needs (Section 3, Housing
Needs Assessment)
An assessment of resources available to meet the City’s objectives regarding housing production
and preservation. Resources include land available for new construction and redevelopment, as
well as financial and administrative resources available (Section 4, Housing Sites)
A review of the constraints to housing production and preservation. Constraints include potential
market, governmental policy, and environmental limitations to meeting the City’s identified
housing needs (Section 5, Constraints to Housing Production)
A statement of the housing plan to address the City’s identified housing needs, including housing
goals, policies, and programs (Section 6, Housing Goals, Policies, Objectives, and Programs)
2.3.3 Regional Housing Needs Allocation (RHNA)
State housing element law requires housing elements to be updated regularly to reflect a community’s
changing housing needs, including preparation of a RHNA plan [Government Code Section 65584(a)]. A
critical measure of compliance is the ability of a jurisdiction to accommodate its share of the regional
housing needs based on a RHNA prepared by HCD for each Council of Governments in the state that
identifies projected housing units needed for all economic segments based on Department of Finance
population estimates. The SCAG is responsible for allocating this total to each of the six counties and 191
cities in the SCAG area. This process is known as the RHNA and occurs every eight years.
SCAG calculates each city and county’s “fair share” of the regional need using a computer model that
weighs factors such as existing population and employment, growth potential, proximity to transit, and
social equity. For each jurisdiction, SCAG distributes the RHNA among four different income groups. This
ensures that each city or county is planning for housing that meet the needs of all economic segments of
the community, including lower income households.
For the City, the RHNA for 2021-2029 is 45 units (SCAG 2020). This includes 20 very low income units, 9
low income units, 11 moderate income units, and 5 above moderate income units. The 2021-2029 Housing
Element demonstrates that the City has the capacity to accommodate this assignment.
2.3.4 Summary of Ability to Meet RHNA
As shown in Table 2.3-1 below, the combination of recently approved housing units (expected to be
occupied in 2022), future affordable units on the Rancho Del Mar site 1, and new accessory dwelling units
(ADUs) can accommodate the RHNA allocation in all income categories. The table illustrates a surplus
capacity of seven lower income units based on projected ADU production over the planning period.
1 In March 2021, the City adopted an Affordable Housing Overlay Zone on the 31-acre Palos Verdes Peninsula
Unified School District (PVPUSD) property located at 38 Crest Road (Rancho Del Mar site). Although the site is
technically non-vacant, roughly three-quarters of the property (23 acres) is open space. The remaining areas are
underutilized and could be repurposed. Consistent with the General Plan and Zoning amendments completed in
2021, the site is viable for 16 units of low/very low income housing.

2.3.5 2021-2029 Goals and Policies
As previously mentioned, based on the City’s ability to meet RHNA allocation as described above, the HEU
is a policy document; no actual development nor rezoning of parcels is included as part of the approval.
The housing goals, policies, objectives, and programs which can be found in Chapter 6 of the HEU reflect
the City’s continued commitment to actively support residential development and plan for the City’s fair
share of regional housing needs.

CHAPTER 3.0 – ENVIRONMENTAL DETERMINATION
3.1 ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED:
The environmental factors checked below would potentially be affected by this project, involving at least
one impact that is a “Potentially Significant Impact," as indicated by the checklists on the following pages.
For each of the potentially affected factors, mitigation measures are recommended that would reduce the
impacts to less than significant levels.
Aesthetics Agriculture and Forestry Resources Air Quality
Biological Resources Cultural Resources Energy
Geology /Soils Greenhouse Gas Emissions Hazards & Hazardous Materials
Hydrology /Water Quality Land Use / Planning Mineral Resources
Noise Population / Housing Public Services
Recreation Transportation Tribal Cultural Resources
Utilities /Service Systems Wildfire Mandatory Findings of Significance
3.2 DETERMINATION
On the basis of this initial evaluation:
1. I find that the project could not have a significant effect on the environment, and a
NEGATIVE DECLARATION will be prepared.
2. I find that although the proposed project could have a significant effect on the
environment, there will not be a significant effect in this case because revisions in the
project have been made by or agreed to by the project proponent. A MITIGATED
NEGATIVE DECLARATION will be prepared.
3. I find the proposed project may have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
4. I find that the proposed project may have a “potentially significant impact” or
“potentially significant unless mitigated impact” on the environment, but at least one
effect (1) has been adequately analyzed in an earlier document pursuant to applicable
legal standards, and (2) has been addressed by mitigation measures based on the earlier
analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is
required, but it must analyze only the effects that remain to be addressed.
5. I find that although the proposed project could have a significant effect on the
environment, because all potentially significant effects (a) have been analyzed
adequately in an earlier EIR or Negative Declaration pursuant to applicable standards,
and (b) have been avoided or mitigated pursuant to that earlier EIR or Negative
Declaration, including revisions or mitigation measures that are imposed upon the
proposed project, nothing further is required.

CHAPTER 4.0 – EVALUATION OF ENVIRONMENTAL IMPACTS
1. A brief explanation is required for all answers except “No Impact” answers that are adequately
supported by the information sources a lead agency cites. A “No Impact” answer is adequately
supported if the referenced information sources show that the impact simply does not apply to
projects like the one involved (e.g., the project falls outside a fault rupture zone). A “No Impact”
answer should be explained where it is based on project-specific factors as well as general standards
(e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific
screening analysis).
2. All answers must take account of the whole action involved, including offsite as well as onsite,
cumulative as well as project-level, indirect as well as direct, and construction as well as operational
impacts.
3. Once the lead agency has determined that a particular physical impact may occur, then the checklist
answers must indicate whether the impact is potentially significant, less than significant with
mitigation, or less than significant. “Potentially Significant Impact” is appropriate if substantial
evidence exists that an effect may be significant. If one or more “Potentially Significant Impact” entries
are marked when the determination is made, an EIR is required.
4. “Negative Declaration: Less Than Significant With Mitigation Incorporated” applies where the
incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a
“Less Than Significant Impact.” The lead agency must describe the mitigation measures and briefly
explain how they reduce the effect to a less than significant level (mitigation measures from earlier
analyses may be cross-referenced).
5. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other California
Environmental Quality Act (CEQA) process, an effect has been adequately analyzed in an earlier
Environmental Impact Report (EIR) or negative declaration. Section 15063(c)(3)(D). In this case, a brief
discussion should identify the following:
a. Earlier Analysis Used. Identify and state where they are available for review.
b. Impacts Adequately Addressed. Identify which effects from the above checklist were within the
scope of and adequately analyzed in an earlier document pursuant to applicable legal standards,
and state whether such effects were addressed by mitigation measures based on the earlier
analysis.
c. Mitigation Measures. For effects that are “Less than Significant with Mitigation Measures
Incorporated,” describe the mitigation measures which were incorporated or refined from the
earlier document and the extent to which they address site-specific conditions for the project.
6. Lead agencies are encouraged to incorporate into the checklist references to information sources for
potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or
outside document should, where appropriate, include a reference to the page or pages where the
statement is substantiated.

7. Supporting Information Sources: A source list should be attached, and other sources used or
individuals contacted should be cited in the discussion.
8. The explanation of each issue should identify:
a. the significance criteria or threshold, if any, used to evaluate each question; and
b. the mitigation measure identified, if any, to reduce the impact to less than significant.

would the project conflict with applicable zoning and
other regulations governing scenic quality?
(d) Create a new source of substantial light or glare
which would adversely affect day or nighttime views
in the area?
5.1.1 Impact Analysis
a) Would the project have a substantial adverse effect on a scenic vista?
b) Would the project substantially damage scenic resources, including, but not limited to, trees, rock
outcroppings, and historic buildings within a state scenic highway?
No Impact. The HEU and SEU are is aboth policy documents and does not include any changes to land
use designations, zoning, building heights and intensities, or residential densities. Further, the
Housing Element and Safety Element includes policies intended to continue to make the City a safe
and desirable place to work and live. All future development in the City would require project-specific
environmental evaluation in order to determine any potential impacts to scenic vistas. Additionally,
no officially designated State scenic highway is located in the City (Caltrans 2021). Potential aesthetic-
related impacts are unique to a project’s location and cannot be meaningfully determined until a
project site has been defined. Any future development would be subject to the City’s zoning
requirements, and any potentially significant impacts identified would be addressed through
mitigation measures specific to the impact. The Project would result in no impacts to scenic vistas or
scenic resources within a State scenic highway.
c) Would the project, in non-urbanized areas, substantially degrade the existing visual character or
quality of public views of the site and its surroundings? (Public views are those that are experienced
from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict
with applicable zoning and other regulations governing scenic quality?
No Impact. As previously mentioned, the Project would implement policies intended to continue to
make the City a safe and desirable place to work and live including efforts such as development and
landscaping policies, among others. The City’s current Zoning Code contains standards intended to
preserve the natural beauty of the City and to maintain visual orderliness, including provisions related
589
City of Rolling Hills 2021-2029 Housing Element Update and Safety Element Update
Rolling Hills, Los Angeles County, California
Chambers Group, Inc.
21330
2
to building standards (height, setbacks, intensities), screening of utilities in development, and outdoor
improvements. All future development in the City would be required to comply with the provisions of
the City’s Zoning Code and undergo project-specific environmental evaluation in order to determine
any potential impacts. The Project would result in no impacts to the visual character or quality of
public views or conflict with applicable zoning and other regulations governing scenic quality.
d) Create a new source of substantial light or glare which would adversely affect day or nighttime views
in the area?
No Impact. Sources of light present throughout the City include residential uses of both interior and
exterior lighting and vehicular traffic, while sources of glare include highly finished building materials
such as glass, and roadway traffic. The Project consists of two a policy documents and would not
directly enable construction or development. Nevertheless, all future residential development
enabled by the City’s General Plan is anticipated to introduce light and glare sources typical of
development; and all future development in the City would be subject to the City’s zoning
requirements. The City’s current Zoning Code contains lighting requirements intended to maintain
public health, safety, and welfare from noxious or offensive illumination, glare, or similar effects. All
future development in the City would be required to comply with the provisions of the City’s Zoning
Code and undergo project-specific environmental evaluation in order to determine any potential
impacts. The Project would result in no impact to the creation of light or glare that would adversely
affect views.
5.2 AGRICULTURE & FORESTRY RESOURCES

AGRICULTURE & FOREST RESOURCES.
(In determining whether impacts to agricultural
resources are significant environmental effects,
lead agencies may refer to the California
Agricultural Land Evaluation and Site Assessment
Model (1997) prepared by the California
Department of Conservation as an optional model
to use in assessing impacts on agriculture and
farmland. In determining whether impacts to
forest resources, including timberland, are
significant environmental effects, lead agencies
may refer to information compiled by the
California Department of Forestry and Fire
Protection regarding the state’s inventory of forest
land, including the Forest and Range Assessment
Project and the Forest Legacy Assessment project;
and forest carbon measurement methodology
provided in Forest Protocols adopted by the
California Air Resources Board. Would the project:

(e) Involve other changes in the existing environment
which, due to their location or nature, could result in

5.2.1 Impact Analysis
a) Would the project convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance
(Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring
Program of the California Resources Agency, to non-agricultural use?
b) Would the project conflict with existing zoning for agricultural use, or a Williamson Act contract?
c) Would the project conflict with existing zoning for, or cause rezoning of, forest land (as defined in
Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section
4526), or timberland zoned Timberland Production (as defined by Government Code section
51104(g))?
d) Would the project result in the loss of forest land or conversion of forest land to non-forest use?
e) Would the project involve other changes in the existing environment which, due to their location or
nature, could result in conversion of Farmland, to non-agricultural use or the conversion of forest land
to non-forest use?
No Impact. The City does not contain any Prime Farmland, Unique Farmland, or Farmland of
Statewide Importance (DOC 2021a). Additionally, no land within the City is under a Williamson Act
contract (DOC 2017). The Project involves updates to the City’s Housing Element and Safety Element,
with no proposed changes to land use designations or zoning of parcels within the City. The City is a
residential community, and no provisions contained in the Housing Element Update or the Safety
Element Update would convert Prime Farmland or any farmland of unique or Statewide importance.
Further, no development is proposed on forestland or timber property zoned Timberland Production.
Any future development proposals would not conflict with an existing Williamson Act contract; that
would result in the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide
Importance to nonagricultural use or result in conversion or loss of forest land. Any future
development on properties zoned agricultural would be analyzed in a future site-specific
environmental document. Therefore, no impacts to agricultural or forestry resources would occur.

ambient air quality standard?
(c) Expose sensitive receptors to substantial pollutant
concentrations?
(d) Result in other emissions (such as those leading to
odors) adversely affecting a substantial number of
people?
5.3.1 Impact Analysis
a) Would the project conflict with or obstruct implementation of the applicable air quality plan?
b) Would the project result in a cumulatively considerable net increase of any criteria pollutant for which
the project region is non-attainment under an applicable federal or state ambient air quality standard?
No Impact. The City is located within the South Coast Air Basin, which is currently designated
nonattainment for ozone and fine particulate matter less than 2.5 microns in diameter (PM2.5)
(SCAQMD 1999). The South Coast Air Quality Management District (SCAQMD) prepared an air quality
management plan (AQMP) for both pollutants in 2016 and is currently working on the 2022 AQMP
(SCAQMD 2021). The Project would not directly result in construction or development activity, nor
would it enable development beyond that which is currently provided for in the City’s General Plan.
The number of residential units that could be developed under the HEU is consistent with the City’s
current General Plan and zoning designations. Potential air quality-related impacts are location-
specific and cannot be assessed in a meaningful way until the location of a project site is known. At
such time that a development proposal is considered, that project will be subject to adopted
development air quality standards; and any impacts identified with the development project will be
addressed through mitigation measures specific to the impact. Short-term air quality impacts resulting
from construction activities, such as dust generated by clearing and grading activities, exhaust
emissions from gas- and diesel-powered construction equipment, and vehicular emissions associated
with the commuting of construction workers, will be subject to SCAQMD air quality management
plans identified above and all other relevant SCAQMD rules and regulations.
Thus, the Project would result in no impacts related to implementation of any applicable air quality
plan, nor would it result in a cumulatively considerable net increase of any criteria pollutant for which
the Project region is nonattainment under an applicable federal or State ambient air quality standard.
c) Would the project expose sensitive receptors to substantial pollutant concentrations?
No Impact. As mentioned, the HEU and SEU are bothis a policy documents and does not include any
changes to land use designations or zoning. Moreover, the Project does not directly enable
construction or development activities. Potential air quality-related impacts are location-specific and
cannot be assessed in a meaningful way until the location of a project site is known. The City’s General
Plan and Municipal Code contain policies and measures related to maintaining air quality in residential
neighborhoods, including protecting neighborhoods from air pollution-generating activities through
site-specific environmental review and appropriate development buffers. At the time that a
development proposal is considered, that project will be subject to the development review process,
and any potentially significant impacts identified would be addressed through mitigation measures
592

specific to the impact. Thus, the Project would result in no impacts related to the exposure of sensitive
receptors to substantial pollutant concentrations.
d) Would the project result in other emissions (such as those leading to odors) adversely affecting a
substantial number of people?
No Impact. Impacts would be considered potentially significant if the Project were to result in the
creation of objectionable odors with the potential to affect substantial numbers of people, or if
construction or operation of the Project would result in the creation of nuisance odors that would be
noxious to a substantial number of people. The City’s General Plan and Municipal Code contain
policies and measures related to maintaining air quality in residential neighborhoods, including
protecting neighborhoods from odor-generating activities through site-specific environmental review
and appropriate development buffers.
Residential development, such as that described in the HEU, is not a land use typically associated with
odor complaints or noxious emissions. Moreover, tThe SEU contains policies to prevent health threats
due to air quality impacts such as those associated with wildfire. The Project would not directly enable
construction or development activities upon implementation. At the time that a development
proposal is considered, that project will be subject to the development review process; and any
potentially significant impacts identified would be addressed through mitigation measures specific to
the impact. The Project would therefore not result in impacts related to emissions adversely affecting
a substantial number of people.

5.4.1 Impact Analysis
a) Would the project have a substantial adverse effect, either directly or through habitat modification,
on any species identified as candidate, sensitive or special status species in local or regional plans,
policies or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife
Service?
No Impact. The City’s environs have the capacity to house a range of plant and wildlife species,
including State and federally listed species. To protect candidate, sensitive, or special status species
all future development in the City would require project-specific environmental evaluation in order
to determine any potential impacts. Potential impacts related to biological resources are unique to a
project’s location and cannot be meaningfully determined until a project site has been defined. Any
future development would be subject to federal, State, regional, and local regulatory requirements
related to biological resources.
Further, the HEU and SEU includes policies intended to lessen impacts to biological resources,
including policies to minimize housing construction in environmentally sensitive areas and policies for
climate change adaptation and resiliency. Additionally, future projects would be evaluated by the City
for their compliance with goals, policies, and measures contained in the City’s General Plan intended
to mitigate potential impacts to natural and biological resources, including those contained in the
Open Space and Conservation Element. Any potentially significant environmental impacts identified
from future development would be addressed through project specific mitigation measures identified
at the time a specific development project is considered by the City. Therefore, the Project would
have no impacts on any candidate, sensitive, or special status species.
b) Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies or regulations, or by the California Department
of Fish and Wildlife or U.S. Fish and Wildlife Service?
c) Would the project have a substantial adverse effect on state or federally protected wetlands (including
but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological
interruption, or other means?
No Impact. A substantial amount of land in the City is constrained from development due to steep
hillsides and canyons, many of which contain intermittently flooded riparian and wetland habitat
(USFWS 2021). However, the HEU and SEU are bothis a policy documents and would not directly
enable construction or development activity. Potential impacts related to sensitive natural
communities, such as riparian or wetland habitats, are unique to a project’s location and cannot be

meaningfully determined until a project site has been defined. Thus, all future development in the
City would require project-specific environmental evaluation. Any potentially significant
environmental impacts identified from future development would be addressed through project-
specific mitigation measures identified at the time a specific development project is considered by
the City. Therefore, the Project would have no impacts on any riparian habitat, other sensitive natural
communities, or on State or federally protected wetlands.
d) Would the project Interfere substantially with the movement of any native resident or migratory fish
or wildlife species or with established native resident or migratory wildlife corridors, or impede the use
of native wildlife nursery sites?
No Impact. The City is a heavily landscaped residential community interspersed with undeveloped
steep hillsides and canyons (City 1990). Within these undeveloped areas, the potential exists for
nesting birds and other species to occur. Nonetheless, the HEU and SEU are is a policy documents
consistent with the City’s General Plan and does not propose any land use or zoning changes. Further,
future development will require site-specific environmental analysis. Potential environmental impacts
identified from future development would be addressed through project-specific mitigation measures
identified at the time a specific development project is considered by the City. Therefore, the Project
would have no impacts to the movement of native resident or migratory fish or wildlife species,
corridors, or nursery sites.
e) Would the project conflict with any local policies or ordinances protecting biological resources, such
as a tree preservation policy or ordinance?
f) Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural
Conservancy Conservation Plan, or other approved local, regional, or state habitat conservation plan?
No Impact. The County of Los Angeles’s Significant Ecological Area (SEA) Program was originally
established as a part of the 1980 County General Plan, to help conserve the genetic and physical
diversity in the County. The SEA Ordinance, which codified the SEA Program, establishes the
permitting, design standards and review process for development within SEAs. The City contains
portions of the Palos Verdes Peninsula and Coastline SEA; however, only areas within unincorporated
Los Angeles County are subject to this ordinance. Further, policies and programs of the HEU promote
infill housing including ADUs. No development would occur pursuant to the SEU. Any development
that occurs pursuant to HEU or SEU policies will occur in already disturbed areas of the community
and will be reviewed and processed in accordance with City planning policies. Therefore, the Project
would not conflict with any local policies, ordinances, or plans protecting biological resources; and no
impacts would occur.

pursuant to §15064.5?
b) Would the project cause a substantial adverse change in the significance of an archaeological resource
pursuant to §15064.5?
c) Would the project disturb any human remains, including those interred outside of formal cemeteries?
No Impact. The Project involves adoption of two a policy documents, the HEU and SEU, which does
not directly propose any ground disturbance. Potential impacts related to cultural resources are
unique to a project’s location and cannot be meaningfully determined until a project site has been
defined. Thus, all future development in the City would require project-specific environmental
evaluation in order to determine any potential impacts. Future development would be subject to
federal, State, and local regulatory requirements related to the discovery and proper handling of
cultural and historic resources, including Public Resource Code (PRC) Section 211083.2, which requires
avoidance and other measures in the event of discovery. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Therefore,
no impacts to cultural resources would occur with implementation of the Project.

a) Would the project result in potentially significant environmental impact due to wasteful, inefficient, or
unnecessary consumption of energy resources, during project construction or operation?
No Impact. The HEU and SEU are is consistent with the City’s General Plan and contain policies to
conserve energy resources. However, potential impacts related to energy resources are unique to a
project and cannot be meaningfully determined until a project has been defined. The HEU also seeks
to conserve energy through public education on the reduction of residential energy use. Any future
development would also be subject to individual review for compliance with federal, State, and local

regulatory requirements related to energy efficiency. Future development projects would incorporate
site-specific infrastructure improvements, as necessary, and would be reviewed by relevant energy
providers to identify necessary energy facility and service connections. Additionally, future projects
would be evaluated by the City for their compliance with goals, policies, and measures contained in
the City’s General Plan intended to mitigate potential impacts to energy resources. Any potentially
significant environmental impacts identified from future development would be addressed through
project-specific mitigation measures identified at the time a specific development project is
considered by the City. Thus, no impacts would occur.
b) Would the project conflict with or obstruct a state or local plan for renewable energy or energy
efficiency?
No Impact. Any future development in the City would be subject to federal, State, and local regulatory
requirements related to energy efficiency. Additionally, goals, policies, and programs related to
reducing greenhouse gas (GHG) emissions (as discussed in Section 5.8: Greenhouse Gas Emissions)
are closely related to reducing energy consumption through the use of alternative forms of energy or
sustainable design features.
Future projects would be evaluated by the City for their compliance with goals, policies, and measures
contained in the City’s General Plan intended to mitigate potential impacts to energy resources. Any
potentially significant environmental impacts identified from future development would be

risk of loss, injury, or death involving seismic-related ground failure, including liquefaction?
iv) Would the project directly or indirectly cause potential substantial adverse effects, including the
risk of loss, injury, or death involving landslides?
No Impact. Rolling Hills is in a seismically active region of southern California, with the Whittier fault,
Newport-Inglewood fault, Palos Verdes fault, Malibu Coast fault, Cabrillo fault, Santa Monica fault,
and Redondo Canyon fault all within 50 miles of the City. The closest active fault to the City is the
Palos Verdes Fault, located within the City boundaries. While there are a number of seismically active
faults in the City and region, there are no active faults with the potential for ground rupture, defined
by the Alquist-Priolo Earthquake Fault Zoning Act. The closest Alquist-Priolo Fault Zone is the
Newport-Inglewood Fault approximately nine miles northeast of the City (City 1990).
Regarding other geologic hazards, much of the existing development in Rolling Hills is located on hilly
terrain highly susceptible to landslide risks. However, the potential for liquefaction, lateral spreading,
and seismically induced dynamic settlement is low (City 1990).
The SEU addresses the protection of the existing and future population and development from both
natural and man-made hazards through a number of goals, policies, implementation programs,
principles, and standards. Among these is Goal 1 of the SEU, which aims for “minimization of loss of
life, injury, and property damage resulting from geologic hazards”. Additionally, the Project includes
implementation of two a policy documents and no development is proposed at this time. All future
development in the City would require project-specific environmental evaluation in order to
determine that any potential impacts are less than significant. Any future development would be
subject to federal, State, and local regulatory requirements related to building design and

construction. Any potentially significant impacts identified would be addressed through mitigation
measures specific to the impact. Therefore, the Project would result in no impacts related to the direct
or indirect cause of potential substantial adverse effects, including the risk of loss, injury, or death,
involving rupture of a known earthquake fault, strong seismic ground shaking, and seismic-related
ground failure, including liquefaction or landslides.
b) Would the project result in substantial soil erosion or the loss of topsoil?
No Impact. The Project consists of two a policy documents and would not directly enable construction
or development activities. Any future development in the City would be subject to State, regional, and
local requirements related to the prevention of erosion of onsite soils, as well as discharge of other
construction-related pollutants, through the preparation and implementation of a Stormwater
Pollution Prevention Plan (SWPPP) and Best Management Practices (BMPs). Additionally, future
projects would be evaluated by the City for their compliance with goals, policies, and measures
contained in the SEU intended to protect lives and property. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Therefore,
the Project would have no impacts related to soil erosion or the loss of topsoil.
c) Would the project be located on a geologic unit or soil that is unstable, or that would become unstable
as a result of the project, and potentially result in on- or off-site landslide, lateral spreading,
subsidence, liquefaction or collapse?
No Impact. As previously discussed, much of the existing development in Rolling Hills is located on
hilly terrain; and many of the City’s canyons exhibit steep slopes with little vegetation coverage. These
areas are highly susceptible to landslide risks. However, the City generally lacks the thick, loose, sandy
soils which lead to liquefaction and ground failure hazards. Thus, the potential for liquefaction, lateral
spreading, and seismically induced dynamic settlement is low (City 1990).
The HEU and SEU are is a policy documents; thus, the Project does not directly propose physical
changes in the environment and does not, in and of itself, enable future development. To account for
any potential instability, all future development projects would be evaluated on a site-specific basis
and would be subject to federal, State, and local regulatory requirements related to building design
and construction. Any potentially significant environmental impacts identified from future
development would be addressed through project-specific mitigation measures identified at the time
a specific development project is considered by the City. Thus, the Project would have no impacts
related to location on a geologic unit or soil that is unstable or that would become unstable as a result
of the Project and potentially result in on or offsite landslide, lateral spreading, subsidence,
liquefaction, or collapse.
d) Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code
(1994), creating substantial direct or indirect risks to life or property?
No Impact. Expansive soils are characterized as fine-grained, such as silts and clays or soils with
variable amounts of expansive clay minerals that can change in volume due to changes in water
content. According to the General Plan, soil types within the City consist predominantly of fertile clays
with some loams and shales (City 1990). Nevertheless, the HEU and SEU are is a policy documents;
thus, the Project does not directly propose physical changes in the environment and does not, in and

of itself, enable future development. Future development would be evaluated in separate, site-
specific CEQA documents and would be subject to federal, State, and local regulatory requirements
related to building design and construction. Potential environmental impacts from future
development would be addressed through project-specific mitigation measures identified at the time
a development project is considered by the City.
e) Would the project have soils incapable of adequately supporting the use of septic tanks or alternative
waste water disposal systems where sewers are not available for the disposal of waste water?
No Impact. With the exception of a Palos Verdes Unified School District site and 13 residences that
have individually or collectively (through the creation of a small sewer district) connected to an
adjacent jurisdiction’s sewer systems, no sanitary sewer system exists in Rolling Hills. Residences are
served by individual septic tanks and seepage pits. These systems are designed to serve single-family
residences and are not conducive to multi-family housing; particularly given the geologic, slope, and
soil constraints in Rolling Hills. However, the HEU and SEU are is a policy documents consistent with
the City’s General Plan and does not propose any land use or zoning changes. Moreover, all future
development would be evaluated on a site-specific basis and subject to federal, State, and local
regulatory requirements related to building design and construction. Any potentially significant
environmental impacts identified from future development would be addressed through project-
specific mitigation measures identified at the time a specific development project is considered by
the City. The Project would have no impacts related to soils incapable of adequately supporting the
use of septic tanks or alternative wastewater disposal systems.
f) Would the project directly or indirectly destroy a unique paleontological resource or site or unique
geological feature?
No Impact. All future development in the City would require project-specific environmental
evaluation in order to determine that any potential impacts are less than significant. Potential impacts
related to paleontological and geologic resources are unique to a project and site and cannot be
meaningfully determined until a project has been defined. In the event that paleontological resources
are discovered during future development projects, applicants will be required to comply with
regulatory standards enumerated under in PRC Section 5097.574, which sets the protocol for proper
handling. Any potentially significant environmental impacts from future development would be
analyzed in a separate CEQA document and addressed through project-specific mitigation measures
identified at the time a development project is considered by the City. Therefore, the Project would
have no impacts related to the direct or indirect destruction of a unique paleontological resource or
site or unique geologic feature.

through sustainable design and renewable energy considerations. Any potentially significant
environmental impacts would be analyzed in a project-specific environmental document and
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. The Project would have no impacts related to the generation of GHG
emissions or conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing
the emission of GHGs.

5.9.1 Impact Analysis
a) Would the project create a significant hazard to the public or the environment through the routine
transport, use, or disposal of hazardous materials?
No Impact. The HEU and SEU are is a policy documents consistent with the City’s General Plan. The
Project does not directly propose physical changes in the environment and does not, in and of itself,
enable future development. Moreover, the SEU addresses the protection of the existing and future
population and development from both natural and man-made hazards through a number of goals,
policies, implementation programs, principles, and standards. Among these are measures to mitigate
the risk from hazardous materials.
Construction activities associated with future individual development projects would likely involve the
temporary transportation, management, and use of oils, fuels and other potentially flammable
substances, such as paints, solvents, and cleaners. Hazardous materials that may be present during
operation of future individual projects are usually associated with landscaping and building
maintenance. Nevertheless, any future development in the City would be subject to federal, State,
and local regulatory requirements related to the transport, use, or disposal of hazardous materials.
All potential environmental impacts resulting from future development would be analyzed in a
separate environmental document and addressed through project-specific mitigation measures
identified at the time a specific development project is considered by the City.
b) Would the project create a significant hazard to the public or the environment through reasonably
foreseeable upset and accident conditions involving the release of hazardous materials into the
environment?
No Impact. Residential uses enabled by the City’s HEU are generally not characterized as substantial
generators of hazardous materials, nor are they anticipated to result in upset or accident conditions
involving the release thereof. Further, Tthe SEU addresses the protection of the existing and future
population and development from both natural and man-made hazards, including hazardous
materials. Regardless, the Project involves two a policy documents and would not directly result in
physical changes in the environment. Any future development would be subject to all applicable
regulatory requirements concerning the proper handling, treatment, and disposal of hazardous
materials. Any potentially significant environmental impacts identified from future development
would be addressed through project-specific mitigation measures identified at the time a specific
development project is considered by the City.
c) Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials,
substances, or waste within one-quarter mile of an existing or proposed school?
No Impact. The City only has one school in its boundary: Rancho Del Mar High School located in the
western portion of the City. Potential hazardous material-related impacts are location-specific and
602

cannot be assessed in a meaningful way until the location of a project site is known. At such time that
a development proposal is considered, that project will be subject to the development review process;
and any potentially significant impacts would be addressed through mitigation measures specific to
the impact. Since the current Project involves two a policy documents and does not directly propose
physical changes in the environment, no impacts related to the emission or handling of hazardous or
acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed
school would occur.
d) Would the project be located on a site which is included on a list of hazardous materials sites compiled
pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to
the public or the environment?
No Impact. According to the Department of Toxic Substances Control (DTSC), no potential hazardous
waste sites are under evaluation in Rolling Hills (DTSC 2021; SWRCB 2021). The City and surrounding
area do not contain heavy industrial uses that would create a hazardous material risk in the event of
a spill, release, or natural disaster. Additionally, the City is not located near any major transit routes
involving transport of a substantial quantity of hazardous material through the City (City 1990).
The Project involves two a policy documents and does not directly propose physical changes in the
environment. Any future development would be subject to all applicable regulatory requirements
concerning the proper handling, treatment, and disposal of hazardous materials. Any potentially
significant environmental impacts identified from future development would be addressed through
project-specific mitigation measures identified at the time a specific development project is
considered by the City. The Project would result in no impacts related to location on a site which is
included on a list of hazardous materials sites compiled pursuant to Government Code Section
65962.5.
e) For a project located within an airport land use plan or, where such a plan has not been adopted,
within 2 miles of a public airport or public use airport, would the project result in a safety hazard or
excessive noise for people residing or working in the project area?
No Impact. The HEU and SEU is aare policy documents that analyzes housing and safety needs in the
City. The City is within 2 miles of the Torrance Airport, which is approximately 1.4 miles from the
northern boundary of the City. However, the City is not located within the airport or airfield safety
hazard zone (ALUC 2003). The Project proposes adoption of the SEU, which is a policy document that
would not result in direct development or construction. Any development that occurs pursuant to
Housing Element or Safety Element policies will be subject to State and local regulations regarding the
transport, use, and disposal of hazardous materials and to City planning, engineering, and building
requirements. No impacts relative to noise hazards are expected to occur as a result of the Project.
f) Would the project impair implementation of or physically interfere with an adopted emergency
response plan or emergency evacuation plan?
No Impact. The City’s Community Wildfire Protection Plan (CWPP) identifies the potential evacuation
routes listed below, which include options for rapid egress from areas within the City if threatened by
a wildfire.

The SEU addresses the protection of the existing and future population and development from both
natural and man-made hazards through a number of goals, policies, implementation programs,
principles, and standards. Among these are measures to provide and maintain an emergency response
system for the City. Moreover, future development in the City would be required to comply with the
provisions of the City’s General Plan and Hazard Mitigation Plan during construction and operation.
Any potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Thus, the Project would result in no impacts related to the
impairment of or physical interference with an adopted emergency response plan or emergency
evacuation plan.
g) Would the project expose people or structures, either directly or indirectly, to a significant risk of loss,
injury or death involving wildland fires?
No Impact. The entire City is designated as Very High Fire Hazard Severity Zone (VHFHSZ) by CAL FIRE
(2011). The SEU and HEU addresses the protection of the existing and future population and
development from both natural and man-made hazards through a number of goals, policies,
implementation programs, principles, and standards. Among these are measures to mitigate the risk
from the hazards of fire and ensure the protection of people and wildlife from hazardous materials in
the community.
Further, future development in the City would be required to comply with the provisions of the City’s
General Plan and CWPP during construction and operation. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Thus, the
Project would not expose people or structures to loss, injury, or death involving wildland fires; and no
impacts would result.

5.10.1 Impact Analysis
a) Would the project violate any water quality standards or waste discharge requirements, or otherwise
substantially degrade surface or ground water quality?
No Impact. The Project involves twoa policy documents which arethat is consistent with the City’s
General Plan and does not directly propose physical changes to the environment. Future development
in the City would be required to follow State, regional, and local regulations regarding onsite
stormwater retention, so that surface waters and the groundwater aquifer are not contaminated with
Project-related pollutants. To comply with federal National Pollutant Discharge Elimination System
(NPDES) requirements and maintain its Municipal Separate Storm Sewer System (MS4) permit, the
City is required to screen and monitor its runoff to avoid compromising downstream water quality
standards. It is also required to implement a number of programs, such as an Illicit Discharge
Elimination Program. The City requires BMPs for construction in order to avoid erosion, pollution,
sedimentation, and runoff that would degrade water quality. Any potentially significant
environmental impacts identified from future development would be addressed through project-
specific mitigation measures identified at the time a specific development project is considered by
the City. Thus, the Project would have no impact related to violation of any water quality standards
or waste discharge requirements or otherwise substantially degrade surface or groundwater quality.
b) Would the project substantially decrease groundwater supplies or interfere substantially with
groundwater recharge such that the project may impede sustainable groundwater management of
the basin?
No Impact. The City’s water infrastructure is owned, maintained, and operated by California Water
Service Palos Verdes District (District). According to the District’s 2020 Urban Water Management
Plan (UWMP), the current water supply for the customers of the District is purchased imported water
and groundwater is not being used as a source of supply (CalWater 2021). Further, all future
development in the City would require project-specific environmental evaluation in order to
determine any potentially significant impacts to groundwater and required project-specific mitigation

measures. Any future development would also be subject to all applicable State, regional, and local
regulatory requirements concerning the efficient use and conservation of water resources, including
measures identified in the City’s General Plan. Therefore, the Project would result in no impacts
related to groundwater supplies or groundwater recharge.
c) Would the project substantially alter the existing drainage pattern of the site or area, including
through the alteration of the course of a stream or river or through the addition of impervious surfaces,
in a manner which would:
i) result in substantial erosion or siltation on- or off-site;
ii) substantially increase the rate or amount of surface runoff in a manner which would result in
flooding on- or off-site;
iii) create or contribute runoff water which would exceed the capacity of existing or planned
stormwater drainage systems or provide substantial additional sources or polluted runoff; or
iv) impede or redirect flood flows?
No Impact. The Project involves two a policy documents which are is consistent with the City’s
General Plan and does not directly propose physical changes to the environment. The City’s SEU
also contains principles and standards intended to minimize risk from flooding or erosion.
Nonetheless, potential impacts related to drainage are unique to a project and cannot be
meaningfully determined until a project site has been defined. Future development in the City
would be required to follow State, regional, and local regulations regarding drainage, erosion, and
runoff. As mentioned, the City is required to screen and monitor its runoff to avoid compromising
downstream water quality standards to comply with federal NPDES requirements and maintain
its MS4 permit. The City also requires BMPs for construction in order to avoid erosion, pollution,
sedimentation, and runoff that would degrade water quality. Any potentially significant
environmental impacts identified from future development would be addressed through project-
specific mitigation measures identified at the time a specific development project is considered
by the City. Thus, the Project would have no impacts.
d) Would the project in flood hazard, tsunami, or seiche zones, risk release of pollutants due to project
inundation?
No Impact. According to Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map
(FIRM) panels 06037C2026G, 06037C2027G, and 06037C1940F, the City is not located in a flood hazard
area and currently has a less than 0.2 percent annual chance to be inundated by flood waters as a
result of a storm event (FEMA 2021). Additionally, the City is not located within a tsunami or seiche
zone (DOC 2021b; DWR 2021). Regardless, all future development in the City would require project-
specific environmental evaluation in order to determine any potential impacts. Future development
would be subject to all applicable federal, State, and local regulatory requirements concerning flood
hazards, including measures identified in the City’s General Plan intended to minimize impacts. Any
potentially significant environmental impacts identified from future development would be addressed
through project-specific mitigation measures identified at the time a specific development project is
considered by the City. Therefore, the Project would result in no impact related to risking release of
pollutants due to Project inundation in flood hazard, tsunami, or seiche zones.
e) Would the project conflict with or obstruct implementation of a water quality control plan or
sustainable groundwater management plan?
606

No Impact. The Project involves updating two a policy documents and does not propose any zoning
or land use changes, or authorize any physical development. Any future development that occurs
pursuant to the HEU or SEU in the City will be subject to State and local regulations regarding water
quality, run-off, and hydrology and to City planning, engineering and building requirements. The
Project would not conflict with or obstruct implementation of a water quality control plan or
sustainable groundwater management plan; thus, no impacts would occur.

5.11.1 Impact Analysis
a) Would the project physically divide an established community?
b) Would the project cause a significant environmental impact due to a conflict with any land use plan,
policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?
No Impact. The City has prepared its HEU and SEU in accordance with Section 65580 and Section
65302(g) of the Government Code, respectively. The updates has have also been prepared consistent
with the City General Plan and the community’s vision of its housing and safety needs and objectives.
Accordingly, the HEU examines the City’s housing needs as they exist today and projects future
housing needs based on RHNA allocation. No change to the land use plan or zoning map is proposed
as part of the HEU. The SEU identifies and offers goals, policies, and actions to minimize the City’s
hazards which pose a risk of injury, death, property loss, and other hardships. Any subsequent
discretionary actions or development that occur pursuant to HEU policies will be reviewed and
processed in accordance with City planning policies. The HEU and SEU hasve been prepared in full
compliance with the State law, and no potential adverse impacts relative to land use would occur.

b) Would the project result in the loss of availability of a locally-important mineral resource recovery site
delineated on a local general plan, specific plan or other land use plan?
No Impact. The City is not designated as having any known mineral resources. Although mineral
resources exist in the area, they are outside the City limits and outside the boundaries of the General
Plan (City 1990). Additionally, the Project proposes implementation of the HEU and SEU, which are is
a policy documents consistent with the General Plan. No land use or zoning changes are proposed,
and the Project would not result in direct physical changes to the environment. All future
development would require project-specific environmental evaluation in order to determine any
potentially significant impacts and would integrate project-specific mitigation measures if needed.
Therefore, the Project would have no impacts on the availability of any known resources or locally
important mineral resource recovery sites.

example, by proposing new homes and businesses) or indirectly (for example, through extension of
roads or other infrastructure)?
b) Would the project displace substantial numbers of existing people or housing, necessitating the
construction of replacement housing elsewhere?
No Impact. As the regional planning agency for the Los Angeles region, SCAG is responsible for
preparing jurisdiction-level forecasts for each city and county in the region. The latest forecasts were
adopted in September 2020 and describe conditions in a base year (2016) and forecast year (2045).
SCAG forecasts indicate that City growth will be flat through 2045, with the latest published forecasts
showing 700 households in 2016 and 700 households in 2045. Population in the City over the
equivalent period is shown as increasing from 1,900 to 2,000, a growth rate of about 5 percent over
29 years (SCAG 2020).
The 2021-2029 RHNA allocation for the City is 45 units, including 20 very low income units, 9 low
income units, 11 moderate income units, and 5 above moderate income units. As previously shown in

Table 2.3-1, the combination of recently approved housing units (expected to be occupied in 2022),
future affordable units on the Rancho Del Mar site, and new ADUs, which have been made easier to
develop under a series of recently passed legislation, can accommodate the RHNA allocation in all
income categories. The table illustrates a surplus capacity of seven lower income units based on
projected ADU production over the planning period. Any subsequent development accomplished
pursuant to the HEU or SEU will be consistent with State and regional growth mandates. The Project
does not include any development that would increase population directly or indirectly and The
Project will not displace housing or people. but, conversely, is intended to promote affordability and
increase housing supply, which can support retention of households in all income categories. No
impacts relative to population or housing would occur as a result of the Project.

No Impact. The Los Angeles County Fire Department provides fire protection services to the City. Fire
Station 56, located at 12 Crest Road West, serves the City under Battalion 14. The Project, which
involves the SEU and HEU, would implement policies to promote maintenance of acceptable service
ratios, response times, and other performance objectives for fire protection. Additionally, since the
City is within the CAL FIRE VHFHSZ, the SEU includes policies to enforce VHFHSZ-specific standards
during development. Compliance with these standards reduces the fire vulnerability of new structures
built in the City. The HEU and SEU are is onlya policy documents, and all future development would
require project-specific environmental evaluation in order to determine any potential impacts to fire
protection. Further, future development would be required to adhere to State and local regulations
as well as the policies, principles, standards, and mitigation as outlined in other sections of the General

5.16.1 Impact Analysis
a) Would the project increase the use of existing neighborhood and regional parks or other recreational
facilities such that substantial physical deterioration of the facility would occur or be accelerated?
No Impact. Impacts to recreational facilities depend upon the location and intensity of a project.
There is one public park, numerous trails, open space areas, three tennis courts, and two equestrian
facilities that will not be impacted by the Project. The HEU and SEU are is a policy documents and does
not authorize future development. All future development would require project-specific
environmental evaluation in order to determine any potential impacts to recreational facilities.
Further, future development would be required to adhere to State and local regulations as well as the
policies, principles, standards, and mitigation outlined in other sections of the General Plan.
Therefore, the Project would have no impact on existing recreational facilities.
b) Does the project include recreational facilities or require the construction or expansion of recreational
facilities which might have an adverse physical effect on the environment?
No Impact. The Project proposes adoption of the HEU and SEU, both of which are is a policy
documents that would not result in direct development or construction. Therefore, the Project would
not construct any recreational facilities or require the expansion of any recreational facilities. No
impacts would occur to or from recreational facilities.

including transit, roadways, bicycle and pedestrian facilities?
b) Would the project Conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)?
c) Would the project substantially increase hazards due to a geometric design feature (e.g., sharp curves
or dangerous intersections) or incompatible uses (e.g. farm equipment)?
No Impact. Rolling Hills has no public roads or streets; thus the City's circulation infrastructure is not
conducive to uses generating high trip volumes (City 2014). Nonetheless, the HEU and SEU are is a
policy documents consistent with the General Plan. The updates does not include any changes to land
use designations, zoning, building heights and intensities, or residential densities. Any future
development would be required to adhere to all programs, ordinances, and policies that address
circulation, including those in the General Plan Circulation Element and the City’s Municipal Code. Any
potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Thus, no circulation-related impacts would result from the Project.
d) Would the project result in inadequate emergency access?
No Impact. Many streets in the community are “dead ends” without emergency vehicle access
alternatives in the event that ingress and egress is blocked (City 2014). However, the SEU addresses
the protection of the existing and future population and development from both natural and man-
made hazards through a number of goals, policies, implementation programs, principles, and
standards. To ensure adequate emergency access, future development in the City would be required
to undergo environmental analysis and comply with the provisions of the Municipal Code during
construction and operation. Any potentially significant environmental impacts identified from future
development would be addressed through project-specific mitigation measures identified at the time
a specific development project is considered by the City. Thus, the Project would result in no impacts
related to emergency access.

According to the California PRC Section 21084, a project may have a significant effect on the
environment if the project “may cause a substantial adverse change in the significance of an historical
resource.” Assembly Bill 52 (AB 52) specifies that a project with the potential for adverse effects on
tribal cultural resources may be considered a significant effect on the environment. Additionally,
Senate Bill 18 (SB 18) requires a government-to-government consultation process initiated by the local
governmental agency prior to adoption or amendment of a General or Specific Plan.
The City, as the Lead Agency pursuant to CEQA and as required by AB 52 and SB 18, has consulted
with the local Native American Tribes in the Project Area. Tribes that are located regionally include:
Gabrieleno Band of Mission Indians - Kizh Nation, Gabrieleno/Tongva San Gabriel Band of Mission

Indians, Gabrielino /Tongva Nation, Gabrielino Tongva Indians of California, Gabrielino-Tongva Tribe,
Santa Rosa Band of Cahuilla Indians, and Soboba Band of Luiseño Indians. Letters were sent to these
Tribes on December 13, 2021. Tribes were requested to respond to AB 52 by January 12, 2022, and
SB 18 by January 27, 2022.
As of the release of this document, the Gabrieleño Band of Mission Indians - Kizh Nation responded
with two separate letters on December 21, 2021 noting that they had no comments or concerns and
no additional information to provide regarding the HEU or SEU, but requesting consultation for any
and all future projects with ground disturbance as shown in Appendix BC: Tribal Consultation
Response. Additionally, the Gabrielino Tongva Indians of California responded noting that the City is
a highly culturally sensitive area and expressed interest in finding out more information regarding the
project, however, after review of the project, they submitted a follow up email stating that they have
no concerns, but requested notification on future projects.
The HEU and SEU are is a policy documents that would not result in direct development or
construction. As noted, to date, two Tribes responded during the consultation process and did not
have any comments or concerns. Similar to the Project, future projects would be required comply
with AB 52 and SB 18, which require consultation with any Tribes that request consultation. The
Project would not cause a substantial adverse change in the significance of a Tribal Cultural Resource
listed or eligible for listing in the California Register of Historical Resources or in the local register of
historical resources as defined in PRC Section 5020.1(k). Thus, no impacts to Tribal Cultural Resources
would occur.

5.19.1 Impact Analysis
a) Would the project require or result in the relocation or construction of new or expanded water,
wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications
facilities, the construction or expansion of which could cause significant environmental effects?
No Impact. The Project is for the adoption of the City’s HEU and SEU, which are is a policy documents
that would not result in direct development or construction. The HEU identifies approved housing
developments and the construction of ADUs within the City to meet RHNA allocation. According to
the HEU, the principal site improvements required upon development of a vacant property in the City
are the undergrounding of electrical lines to the structure, installation of a septic system, and
conformance to the City’s outdoor lighting standards.
All future development in the City would require project-specific environmental evaluation and would
be subject to all applicable State, regional, and local regulatory requirements concerning the
installation of utilities. Any potentially significant environmental impacts identified from future
development would be addressed through project-specific mitigation measures identified at the time
a specific development project is considered by the City. The HEU and SEU are is a policy documents
that would not result in direct development or construction. Therefore, the Project would have no
impacts regarding the construction or expansion of new or expanded water, wastewater treatment
or stormwater drainage, electric power, natural gas, or telecommunications facilities.
b) Would the project have sufficient water supplies available to serve the project and reasonably
foreseeable future development during normal dry and multiple dry years?
No Impact. According to the 2020 UWMP, the District’s only source of water supply is imported,
purchased water from the West Basin Municipal Water District (WBMWD) (CalWater 2021). The
WBMWD Draft 2020 UWMP states that it will be able to serve 100 percent of projected demands in
normal, single-dry and multiple-dry years. As such, the District expects that, under all hydrologic
conditions, purchased water supplies (in combination with the future recycled supplies) will fully serve
future potable demands (CalWater 2021).
Further, all future development in the City would require project-specific environmental evaluation
in order to determine any potential impacts to groundwater. Any future development would also be
subject to all applicable State, regional, and local regulatory requirements concerning the efficient
use and conservation of water resources, including measures identified in the City’s General Plan. Any
potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Therefore, the Project would result in no impacts related to water
supply availability.
c) Would the project result in a determination by the wastewater treatment provider which serves or
may serve the project that it has adequate capacity to serve the project’s projected demand in addition
to the provider’s existing commitments?
616

No Impact. Wastewater treatment in the City generally occurs through private septic tanks, as only
several parcels on the western periphery of the City have access to sanitary sewer. For these several
parcels, the Los Angeles County Sanitation Districts (LACSD) owns, operates, and maintains the sewer
system consisting of gravity sewers, pumping stations, and force mains to collect wastewater from
the Palos Verdes District service area (Sanitation District #5). The LACSD’s Joint Water Pollution
Control Plant (JWPCP) provides the wastewater service for the District service area. It provides
advanced primary and partial secondary treatment for 400 million gallons per day (MGD) of
wastewater and serves a population of approximately 4.8 million people (LACSD 2021). This plant
currently processes 260 MGD; thus, the system has adequate capacity for the Project (CalWater 2021).
Since the Project proposes adoption of two a policy documents, all future development in the City
would require project-specific environmental evaluation in order to determine any potential impacts
related to wastewater. Any future development would also be subject to all applicable State, regional,
and local regulatory requirements concerning the efficient use and conservation of water resources,
including measures identified in the City’s General Plan. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Therefore,
the Project would result in no impacts related to wastewater treatment.
d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local
infrastructure, or otherwise impair the attainment of solid waste reduction goals?
e) Would the project comply with federal, state, and local management and reduction statutes and
regulations related to solid waste?
No Impact. The closest landfill to the City is the Savage Canyon Landfill in Whittier, California. This
landfill has a remaining capacity of 9,510,833 tons and is not expected to close until 2055 (CalRecycle
2021). Since the Project proposes adoption of twoa policy documents, all future development projects
would require an environmental analysis to ensure compliance with the State and local standards and
the federal, State, and local management and reduction statutes and regulations related to solid
waste. Therefore, the Project would have no impact in regard to an increase in solid waste generation
or complying with applicable regulations related to solid waste.

5.20.1 Impact Analysis
a) Would the project impair an adopted emergency response plan or emergency evacuation plan?
No Impact. The entire City is designated as a VHFHSZ by CAL FIRE (CAL FIRE 2011). As mentioned in
Section 5.9, the City’s CWPP identifies the potential evacuation routes described below, which include
options for rapid egress from areas within the City if threatened by a wildfire.
Main Gate at Rolling Hills Road and Palos Verdes Drive North
Crest Gate at Crest Road near Crenshaw Boulevard
Eastfield Gate at Eastfield Drive and Palos Verdes Drive East
Crest Road East (emergency access only)
The SEU and HEU addresses the protection of the existing and future population and development
from both natural and man-made hazards through a number of goals, policies, implementation
programs, principles, and standards. Among these are measures to mitigate the risk from the hazards
of fire. Regardless, potential impacts related to emergency response and evacuation are unique to a
project and cannot be meaningfully determined until a project has been defined. Therefore, future
development in the City would require individual environmental analysis to ensure compliance with
the provisions of the City’s General Plan and CWPP during construction and operation. Any potentially
significant environmental impacts identified from future development would be addressed through
project-specific mitigation measures identified at the time a specific development project is
considered by the City. Thus, the Project would result in no impacts related to the impairment of or
physical interference with an adopted emergency response plan or emergency evacuation plan.
b) Would the project, due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and
thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled
spread of a wildfire?
No Impact. As mentioned above, the entire City is designated a VHFHSZ by CAL FIRE, and a substantial
amount of land in the City is steep hillsides and canyons (CAL FIRE 2011). Although the SEU and HEU
includes measures to mitigate the risk of fire hazards, potential impacts related to fire exacerbation
are unique to a project and cannot be meaningfully determined until a project has been defined. Thus,
future development in the City would require separate environmental analysis to ensure compliance
with the provisions of the City’s General Plan and CWPP during construction and operation. Any
potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development
project is considered by the City. Thus, the Project would result in no impacts related to wildfire
exacerbation.

No Impact. Principal site improvements required upon development of a vacant property in the City
are the undergrounding of electrical lines to the structure, installation of a septic system, and
conformance to the City’s outdoor lighting standards. The entire City is designated a VHFHSZ by CAL
FIRE; however, the SEU includes measures to mitigate the risk of fire hazards. Although not anticipated
under the HEU or the SEU, potential impacts related to utility installation and fire exacerbation are
unique to a project and cannot be meaningfully determined until a project has been defined. Thus,
future development in the City would require separate environmental analysis to ensure compliance
with the provisions of the City’s General Plan and CWPP during construction and operation. Any
potentially significant environmental impacts identified from future development would be
addressed through project-specific mitigation measures identified at the time a specific development

d) Would the project expose people or structures to significant risks, including downslope or downstream
flooding or landslides, as a result of runoff, post-fire slope instability or drainage changes?
No Impact. As mentioned above, the entire City is designated a VHFHSZ by CAL FIRE, and a substantial
amount of land in the City is steep hillsides and canyons highly susceptible to landslide risks (CAL FIRE
2011). Although the SEU includes measures to mitigate the risk of fire hazards, potential impacts
related to post-fire instability and drainage changes are unique to a project and cannot be
meaningfully determined until a project has been defined. Thus, future development in the City would
require separate environmental analysis to ensure compliance with the provisions of the City’s
General Plan and CWPP during construction and operation. Any potentially significant environmental
impacts identified from future development would be addressed through project-specific mitigation
measures identified at the time a specific development project is considered by the City. Thus, the
Project would result in no impacts related to post-fire slope instability or drainage changes.

c) Does the project have environmental effects which will cause substantial adverse effects on human
beings, either directly or indirectly?
No Impact. As demonstrated throughout this document, the Project would have no impacts to
Aesthetics, Agricultural Resources, Air Quality, Biological Resources, Cultural Resources, Energy,
Geology and Soils, Greenhouse Gas Emissions, Hazards and Hazardous Materials, Hydrology and
Water Quality, Land Use and Planning, Mineral Resources, Noise, Population and Housing, Public
Services, Recreation, Transportation, Tribal Cultural Resources, Utilities and Service Systems, or
Wildfires. Implementation of the City’s HEU and SEU will not create any significant or adverse impacts
and would therefore not contribute to any cumulatively considerable impacts. Potential site-specific
impacts that cannot be known at this time would be addressed in conjunction with any development
proposal submitted for the individual project sites. The Project involves adoption of two a policy
documents consistent with the General Plan and does not include any changes to land use
designations, zoning, building heights and intensities, or residential densities. Therefore, the Project
would have no impacts or cumulatively considerable impacts on the environment or human beings.

Introduction
Safety Element 1
Introduction
The Safety Element provides the City of
Rolling Hills’ (City’s) goals, policies, and
actions to minimize the hazards to safety in
and around Rolling Hills. The Element
evaluates natural and human-caused safety
hazards that affect existing and future
development and provides guidelines for
protecting the community from harm. The
Element describes existing and potential
future conditions and sets policies for
improved public safety. The goal of the Safety
Element is to reduce the risk of injury, death,
property loss, and other hardships to
acceptable levels.
City Setting
Rolling Hills covers an area of approximately
three square-miles on the Palos Verdes
peninsula, approximately 18 miles south of
downtown Los Angeles. The topography of
the city and peninsula area is unique in that it
rises above the Los Angeles Basin with rolling
hills, steep slopes, and canyons. The city itself
is in the San Pedro Hills. Due to its location
near the coast, the area is generally cooler
and has fewer air quality concerns compared
to the nearby Los Angeles Basin. Table 1
summarizes the climatology of the area.
Rolling Hills City Hall
Rolling Hills is a residential community that
consists of large parcels and ranch-style
homes and has a sizable older adult1
population of about 513 (28% of the city’s
total population). Important community
demographic data for Rolling Hills is included
in Table 2. The city is also an equestrian
community, as many of residents are horse
owners or have horses on their property.
Regulatory Setting
Section 65302(g) of the California
Government Code requires that the General
Plans include a Safety Element for the
protection of the community from any
unreasonable risks associated with the effects
of seismically induced surface rupture,
ground shaking, ground failure, tsunami,

seiche, and dam failure; slope instability
leading to mudslides and landslides;
subsidence and other geologic hazards;
flooding, and wildland and urban fire. In
addition, Safety Elements are required to
address non-hazard specific issues such as
peak load water supply, evacuation routes,
and military installations.
Senate Bill 379, adopted on October 8, 2015,
requires cities to include climate change
adaptation and resilience into the general
plan process. To comply with SB 379, this
Safety Element includes a vulnerability
assessment; adaptation and resilience goals,
polices, and objectives; and feasible
implementation measures.
Senate Bill 99, adopted August 30, 2020,
requires the cities to “identify residential
developments in any hazard area identified in
the safety element that does not have at least
two emergency evacuation routes.” SB 99
does not define neighborhood and cities are
expected to define neighborhoods based on
their community.
Relationship to Other Documents
The Rolling Hills Safety Element is one of
several plans that address safety in the City.
The Safety Element must be consistent with
these other plans to ensure the City has a
unified strategy to address safety issues. The
Safety Element includes information and
policies from the following documents to
ensure consistency.
Other General Plan Elements
The Safety Element is one section of the
Rolling Hills General Plan. Other elements
include Land Use, Transportation, Housing,
628
Introduction
Safety Element 3
Conservation, Open Space and Recreation
and Noise. Policies in these other elements
may be related to safety issues. Information
and policies in the Safety Element should not
conflict with those in other elements.
Hazard Mitigation Plan
The City’s Hazard Mitigation Plan includes
resources and information to assist the City of
Rolling Hills, its residents, and public and
private sector organizations in planning for
hazard events. The Plan provides a list of
activities that may assist the City in reducing
risk and preventing loss from future hazard
events. The action items address multi-hazard
issues, as well as activities specifically for
reducing risk and preventing losses relating to
earthquake, land movement, wildfire, and
drought.
Community Wildfire Protection Plan
The City’s Community Wildfire Protection
Plan (CWPP), adopted in July 2020, seeks to
reduce wildfire risk in Rolling Hills. The Plan
was developed collaboratively among
stakeholders including the community, the
City of Rolling Hills, the Rolling Hills
Community Association, and the Los Angeles
County Fire Department, and the Los Angeles
Sheriff’s Department. The Plan includes fire
mitigation and evacuation strategies for the
community.
Critical Facilities and
Infrastructure
Critical facilities are places that provide
emergency services or serve people who
would be impacted by an emergency.
Examples include hospitals, fire stations,
police stations, emergency services facilities,
utility facilities, and communication facilities.
Critical facilities can also include the
transportation system and schools. Due to
the size and composition of Rolling Hills,
many of the critical facilities that serve the
city are located outside of city limits. No areas
in Rolling Hills have been identified as lacking
emergency service. Critical facilities that serve
the city are shown in Figure 1 and include:

Hazards of Concern
Geologic Hazards
Geologic processes that pose a threat to life,
health, property, or infrastructure are
considered geologic hazards. Natural geologic
hazards that have the potential to affect
Rolling Hills include seismic hazards,
landslides, liquefaction, expansive soils, and
weathering. In most cases, these natural
processes cannot be prevented; however, the
magnitude of destruction resulting from
natural geologic hazards can be reduced
through planning policies and measures.
Landslide Hazards
Landslide activity refers to a wide range of
gravity driven downslope earth movement,
including rockslides, rotational slips,
mudslides, and shallow debris flows.
Geological and geomorphological conditions
such as soil type, soil strength, slope angle,
and slope height predispose slopes for failure.
Other factors affecting the susceptibility to
slope failure include the amount of
precipitation, vegetation on the slope,
groundwater seepage, and human
modifications to the slope. Landslides often
result in damage to property and roadways
and can cause them to become unsafe due to
displacement of the subsurface.
Much of the existing development in Rolling
Hills is located on hilly terrain and have a
greater potential to experience landslide
hazards. Many of the canyons in Rolling Hills
exhibit steep slopes with little vegetation
coverage, leaving them susceptible to slope
failure. Figure 2 shows the landslide zones in
the City of Rolling Hills, as mapped by the
California Geological Survey (CGS). Landslide
activity has been well documented in the
region. Relicts of landslides and rockslides are
present throughout the City of Rolling Hills.
2 “Beginning in” is defined as the first noted event of major
rock movement
The following major landslides have occurred
in and adjacent to the city. All are in the
landslide hazards areas identified in Figure 2:
▪ Portuguese Bend Landslide: Beginning in2
1956 over approximately 270 acres in
Rancho Palos Verdes
▪ Abalone Cove Landslide: Beginning in
1974 over 80 acres in Rancho Palos
Verdes
▪ Klondike Canyon Landslide: Beginning in
1979 over to the south near the coastline
▪ Flying Triangle Landslide: Beginning in
1970s or 1980s over approximately 70
acres in the southeast area of the city
The Flying Triangle Landslide, shown in Figure
2, continues to impact the southeast portion
of the city through impacts to private roads
and above-ground utility lines. This area is
relatively unsuitable for development due to
the ongoing changes in topography.
Seismic Hazards
Rolling Hills is in a seismically active region of
southern California. The last major
earthquake in the Los Angeles area was the
5.1 magnitude La Habra earthquake in 2014.
Rolling Hills is within 50 miles of the Whittier
fault, Newport-Inglewood fault, Palos Verdes
fault, Malibu Coast fault, Cabrillo fault, Santa
Monica fault, and Redondo Canyon fault.
Analysis of seismic data from the region
indicates that the Whittier and Newport-
Inglewood faults may generate a maximum
credible earthquake of magnitude 7.2 and
7.4, respectively (SCEC 2013). Figure 3 shows
the faults in the vicinity of Rolling Hills.
Typically, seismic shaking and fault rupture
are primary hazards as they occur as a direct
result of the interaction between the seismic
wave energy and the earth’s surface.
Secondary hazards, such as liquefaction and
earthquake-induced landslides, occur as a
result of the primary earthquake hazards.

Hazards of Concern
Safety Element 9
Often, earthquake activity can result in other
effects such as building damage/collapse,
infrastructure failure, pipeline breakage, and
damage to transportation and
communication facilities. The size of the
earthquake and distance from the fault
rupture zone typically determine the severity
of these events.
Seismic Shaking
Seismic shaking, or ground shaking, refers to
the movement of the earth’s surface resulting
from the energy release by an earthquake.
Seismic shaking is typically the primary cause
of property damage resulting from
earthquake activity. Seismic shaking can
destroy buildings, roadways, powerlines, and
pipelines. Energy transmitted through the
ground can travel hundreds of miles and may
cause damage in many locations
simultaneously. Closer proximity to the fault
rupture area results in stronger shaking in
that location.
The amount of ground shaking that occurs in
a location depends on the magnitude of the
earthquake, the distance from the epicenter,
and local soil conditions. The intensity of
ground shaking is related to the peak ground
velocity during an earthquake. As shown in
Figure 4, the earthquake shaking potential for
Rolling Hills is low to moderate. The intensity
of seismic shaking is measured using the
Modified Mercalli scale.
According to the CGS, an active fault is one
that has experienced surface movement in
the past 11,000 years. The city is located near
a number of active faults, including the
Cabrillo Fault in city limits. Table 3 includes a
list of nearby faults, their respective distance
from the city, the maximum credible
earthquake generated from each fault, and
the likelihood of earthquake occurrence in
each case.
The San Andreas fault is located
approximately 80 miles to the east of Rolling
Hills. Although the San Andreas fault is
located at a greater distance from the city,
seismic shaking originating from earthquakes
occurring along the San Andreas fault poses a
threat to the city. Figure 3 identifies the
active and inactive faults located in the city
and vicinity.
Fault Rupture
Fault Rupture occurs when seismic movement
on a fault break through the earth’s surface.
Hazards related to fault rupture arise when
structures are built near or on top of an active
fault. While there are a number of seismically
active faults in the city and region, there are
no active faults with the potential for ground
rupture, defined by the Alquist-Priolo
Earthquake Fault Zoning Act and delineated
by CGS. Figure 3 shows the designated
Alquist-Priolo study zones, the closest of
which is the Newport-Inglewood Fault
approximately nine miles northeast of the
city.

Liquefaction and Settlement
Liquefaction is a ground failure phenomenon
that occurs as a result of a seismic event.
Liquefaction increases water content in
surface soils until the soil reaches a semi-
liquid state, contributing to a reduction in
support, and ultimately resulting in shifting or
subsidence of buildings and utilities. Ground
failure typically occurs when the following
conditions exist:
▪ Loose, unconsolidated granular soils
▪ Shallow groundwater
▪ Strong seismic ground shaking
While Rolling Hills has moderate to high
seismic shaking potential, the subsurface soils
generally lack saturated alluvial deposits and
thick, granular soils. Figure 5 shows the
liquefaction hazard areas, which are in the
low-lying areas to the east and north,
generally surrounding the Los Angeles Harbor
and Harbor Lake. Liquefaction potential for
Rolling Hills is low, as shown in Figure 5.
Earthquake Induced Landslides
Ground failure or destabilization of slopes
resulting from an earthquake can also occur
following seismic activity in the form of
Earthquake-Induced Landslides. Earthquake-
induced landslides typically occur in areas
with steep slopes or unstable soil conditions.
As discussed above under Landslide Hazards,
the risk of landslide activity in Rolling Hills is
high. Much of the city overlies areas that have
been identified as landslide zones by the CGS.
Risk of landslide activity increases following
rainfall events that result in saturated soils.
Both shallow and deep seeded landslides
have historically occurred in the city.
Flooding
Rolling Hills participates in the Federal
Emergency Management Agency’s (FEMA)
National Flood Insurance Program. According
to the FEMA flood maps, the city is not
located in a flood hazard area and currently
has a less than 0.2 percent annual chance to
be inundated by flood waters as a result of a
storm event (FEMA 2008). Overall, the city is
not in any immediate risk from flooding
caused by overflowing water bodies or heavy
rains. However, runoff and minor flooding
pose a risk if drainage systems fail along
canyon bottoms, where natural drainage
leads.
Dam Inundation
No water storage facilities that the State of
California identifies as dams are located in
Rolling Hills. Just outside city limits are three
water storage facilities identified as dams,
which include:
▪ Palos Verdes Reservoir. Owned by the
Metropolitan Water District of Southern
California and located at the southeast
corner of Palos Verdes Drive East and
Palos Verdes Drive North. According to
the California Department of Water
Resources, the reservoir can hold
approximately 1,100 gallons of water and
has an extremely high downstream
hazard.
▪ 10 MG Walteria and 18 MG Walteria.
Two reinforced concrete tanks which are
owned by the City of Torrance and
located at Crenshaw Boulevard and Crest
Road. The tanks can hold 31 and 58 acre-
feet (AF) of water, respectively.
Senate Bill 92, adopted in 2017, is a new dam
safety requirement that requires dam owners
to map the downstream inundation areas for
dams governed by the Department of Water
Resources. Figure 6 shows the inundation
areas for the nearby water storage facilities.
Due to their locations and the topography of
the area, the inundation areas do not enter or
affect any portion of the city.

Wildland and Urban Fires
The entire City of Rolling Hills is designated a
Very High Fire Hazard Severity Zone (VHFHSZ)
by the California Department of Forestry and
Fire Protection (CalFire), as shown in Figure 7.
Rolling Hills terrain is comprised of several
large and steep canyons that limit and
challenge vegetation management and
present conditions where a fire can quickly
travels up and downslope to nearby homes.
Due to the rural nature and large residential
lots, many homes are surrounded by more
substantial vegetation and dense brush than
in more suburban settings. The bridle trails
for hikers and equestrian access also contain
dense vegetation and management
difficulties, which contributes to the fire risk
of the city. Electrical power lines pose a
hazard to starting fires in the city if lines are
not automatically de-energized when
knocked down by extreme weather or if the
surrounding vegetation is not adequately
managed.
There is a history of fires in the city and the
surrounding Palos Verdes Peninsula. Three
major fires have been documented on the
Peninsula and in the city in:
▪ 1923: an estimated 4,000 acres burned in
Palos Verdes Hills
▪ 1945: 3,000 acres burned
▪ 1973: approximately 900-925 acres
burned, 12 homes destroyed, and 10
homes damaged
▪ 2005: 212 acres burned near Del Cero
Park
▪ 2009: 230 acres burned, 6 homes
damaged, and forced 1,200 residents on
the Peninsula to evacuate
▪ 2015: 3 acres burned

For many of the developed residences in the
city that are vulnerable to fires, their risk may
increase with construction techniques that
may not meet current wildfire standards.
Rolling Hills Building Code and Los Angeles
County Fire Department, under the VHFHSZ
standards, require new development to
include more stringent design and material
standards for roofing, eaves, and rafter tails
as well as exterior finishes and fire buffer
zones. While compliance with these
standards reduces the vulnerability to new
structures, existing structures that have not
complied with these standards may be
susceptible to undue fire risk.

Hazardous Materials
According to the Department of Toxic
Substances Control (DTSC), there are no
hazardous waste sites or facilities in Rolling
Hills (DTSC 2020). The city and surrounding
area do not contain heavy industrial uses that
would create a hazardous material risk in the
event of a spill, release, or natural disaster.
The city is not located near any major transit
routes involving transport of a substantial
quantity of hazardous material through the
city. However, the nearby oil refineries
(located along Sepulveda Boulevard
approximately six miles northeast) and Port
operations (located approximately three
miles to the east) could create air quality
impacts if wind patterns and release events
occur. Air quality impacts are discussed in the
Open Space and Conservation Element of the
Rolling Hills General Plan.
Community
Communication
Emergency Response and
Evacuation
Police Response and Crime
The Los Angeles County Sheriff’s Department
is contracted with the city to provide police
services and protection to the city. The
Lomita Station of the Sheriff’s Department
located at 26123 Narbonne Avenue serves
the city.
According to the Lomita Station crimes report
from January 1, 2020, through December 31,
2020, Rolling Hills had 7 reported crimes
(LACSD 2020). The crimes were related to
theft, burglary, and arson. Outside the city
limits and in the Lomita District, 401 crimes
were reported during this same period, 79 of
which were violent crimes (LACSD 2021). The
difference in crimes in the city and the
surrounding area is attributed to the private
nature of the city. There are three entrances
to the city, all of which are gated and staffed
24 hours a day. Visitors are required to be on
a resident’s guest list to enter city limits,
reducing crime in the city and demand on Los
Angeles County Sheriff’s Department.
Fire Response
The Los Angeles County Fire Department
provides emergency operations support to
the City and participates in the California
mutual aid system. Mutual aid is emergency
assistance that is dispatched upon request
across jurisdictional boundaries. Fire Station
56, located at 12 Crest Road West, serves the
city under Battalion 14, which also serves the
remaining Palos Verdes Peninsula, Lomita,
and Avalon Canyon. Fire response constraints
in the city include ability to access certain
homes or areas due to inadequate road
widths for fire maneuvering. One of the major
topics of concern related to fire response in
the city relates to vegetation clearing along
roadways. Ten-foot clearance on each side of
the roadway, especially the limited access
roads, is important for fire response and
evacuation during a fire, according to Scott
Hale, Assistant Fire Chief.
Evacuation Strategies and Routes
Because a variety of hazards could affect city
residents, it is vital to identify critical routes
for evacuation in the event of a major event.
Senate Bill 99, adopted August 30, 2020,
requires cities to “identify residential
developments in any hazard area identified in
the safety element that does not have at least
two emergency evacuation routes.” Due to
the size of Rolling Hills and that it has four
evacuation routes, no neighborhoods have
been identified as not having two evacuation
routes. As shown on the Figure 8, the
evacuation routes also connect to major
643

roadways in the area that are multi-
directional such as Crenshaw Boulevard, Palos
Verdes Drive North and Palos Verdes Drive
East.
Figure 8 identifies the existing evacuation
routes in the city, which are:
▪ Main Gate at Rolling Hills Road and Palos
Verdes Drive North
▪ Crest Gate at Crest Road near Crenshaw
Blvd
▪ Eastfield Gate at Eastfield Drive and Palos
Verdes Drive East
▪ Crest Road East Gate at the end of Crest
Road East
Crest Road East Gate has been updated with a
motor and has no guards. This gate is
available as an emergency exit to the city
during emergencies. The City’s recently
adopted CWPP establishes evacuation
strategies and methodologies, including:
▪ Using the City’s Block Captains3 as
important coordinators for residents
▪ Communication goals between the City,
emergency responders, Rolling Hills
Community Association, and residents
▪ Details for residents regarding how
people get notified during an evacuation
▪ Responsibilities and operations of the
Emergency Operations Center
Disease Prevention
As evidenced by the COVID-19 pandemic,
unforeseen infectious diseases can be
disastrous for communities, especially
vulnerable groups such as older adults, and
people with compromised immune systems.
The City worked diligently during the
pandemic to minimize risk to community
members. The Block Captains regularly
checked in on old adults in the community,
Fire Station Trail
3 The Rolling Hills Block Captain Program is a city-sponsored,
resident-based community program of volunteers. Their role is
to get to know neighbors, help them to prepare for an
emergency, and be a liaison between first responders and City
of Rolling Hills during an emergency.
645

finding out what residents needed, helping
run errands, and providing hand sanitizer
Additionally, the City disseminated
information regularly including where to buy
groceries at the beginning of the pandemic,
testing information, and more. Policies
regarding infectious disease can help expedite
recovery and prepare the community for
future risks.
Climate Change
Climate change is expected to affect future
occurrences of natural hazards in and around
Rolling Hills. Some hazards are projected to
become more frequent and intense in the
coming decades, and in some cases, climate
impacts have already begun.
In developing the Safety Element, the City
competed a Climate Change Vulnerability
Assessment consistent with Government
Code Section 65302(g), which assesses how
the populations and assets in Rolling Hills are
vulnerable to different climate hazards. The
full Climate Change Vulnerability Assessment
can be found in Appendix A: Existing
Conditions Report. According to the
Vulnerability Assessment, the city is most
vulnerable to wildfire impacts, extreme heat,
and landslide impacts from climate change.
According to the Vulnerability Assessment
and the California’s Fourth Climate Change
Assessment, Rolling Hills can expect the
following changes to natural hazard events:
▪ Projected annual average maximum
temperature is expected to increase in
Rolling Hills between 1.8- and 6.6-degrees
Fahrenheit (°F) compared to 1990,
depending on the greenhouse gas (GHG)
emissions scenario.4
4 The Vulnerability Assessment uses two GHG emissions
scenarios: Representative Concentration Pathway (RCP) 4.5
and RCP 8.5. RCP 4.5 describes a scenario in which GHG
▪ Extreme heat events are also expected to
increase in Rolling Hills. The annual
number of average extreme heat days is
projected to increase from a baseline of 4
between 1950 and 2005 to 8 or 14
between 2030 and 2099, depending on
the GHG emissions scenario.
▪ Although only small changes in average
precipitation are projected, the Los
Angeles Region, which includes Rolling
Hills, is expected to experience dry and
wet precipitation extremes and higher
frequency and severity of storms.
Increasing storm intensity may
exacerbate landslide hazards in the city.
Warmer and drier conditions state-wide
could increase the prevalence of drought
conditions that could impact Rolling Hills.
▪ Wildfire is projected to increase over all
of southern California.
Vulnerable Populations
and Assets
As climate change occurs, communities will
be affected to varying degrees and impacts
depending on the hazard as well as how
sensitive the communities are to impacts.
Virtually all people and assets in a community
will be affected by climate change in some
way, but some communities may be more
sensitive. The Vulnerability Assessment
identified the following sensitivities:
Populations
▪ Children. Approximately 6.6 percent of
the total population in Rolling Hills are
ten years old or younger.
▪ Persons in Poverty. This is identified for
people living in households with an
income below the poverty limit, which is
$26,200 for a household of four people.
There are approximately 26 people in
emissions peak around 2050 and then decline. RCP 8.5 is the
scenario in which GHG emissions continue to rise through 2050
before leveling off around 2100.
646
Climate Change
Safety Element 21
Rolling Hills who live in poverty, or
approximately 1.6 percent of the total
population for whom poverty status can
be determined.
▪ Persons with Chronic Health Conditions.
These are people who have a long-term
or permanent health condition that can
create regular challenges in their day-to-
day lives. These health problems include
obesity, cancer, heart disease, and
arthritis. In addition, those with any kind
of disability, including mobility challenges,
hearing, or vision impairments,
behavioral disabilities, and challenges
living independently or taking care of
themselves. Approximately 11.5 percent
of the population have identified having a
disability.
▪ Renters. These are people who live in
homes that they (or the head of their
household) do not own. Approximately 24
housing units, or 4 percent of the housing
units in Rolling Hills, are renter-occupied.
▪ Older Adults. These are persons 65 years
or older are more at risk for climate
change impacts, especially those living
alone. 28 percent of the population of
Rolling Hills are over 65 years, and 15
percent of those over 65 years live alone.
▪ Limited English Proficiency.
Approximately three percent of
households have identified being limited
English-speaking. Of those, a majority
spoke Asian and Pacific Island languages
and Spanish.
Infrastructure
▪ Access Roads. These roadways are one of
a few, or the only, ways in and out of
some communities or neighborhoods.
The single or limited number of entry and
exit points does not make the road itself
more vulnerable than other roads, but
loss of these roadways can effectively cut
off large numbers of people from other
areas in the Palos Verdes Peninsula and
the rest of Los Angeles County.
Portuguese Bend Road and Crest Road
are the primary access roads into and out
of the city.
▪ Bridle Trails. Throughout the community
are over 25 miles of trails available to
residents and non-city residents who
obtain permits. The trails are maintained
by the Rolling Hills Community
Association and located primarily in
canyon areas.
▪ Electrical Substations. Electrical
substations are facilities that convert
electricity from one voltage to another,
making it suitable for long-distance
transmission or for use by homes,
businesses, and other electrical
customers. There are no electrical
substations located in city limits, but
three are located near the city in Rancho
Palos Verdes and owned/operated by
Southern California Edison.
▪ Electrical Utility Lines. These lines
transmit and deliver electricity from
Southern California Edison to the city. The
city has both underground and overhead
electric utility lines.
▪ Natural Gas Transmission Pipelines.
Natural gas pipelines carry large volumes
of natural gas between communities.
There are no transmission lines in the
city. One transmission line ends at the
intersection of Rolling Hills Road and
Palos Verdes Drive North, adjacent to city
limits.
▪ Water Reservoirs and System. The
system that stores and supplies drinking
water for residents. Palos Verdes Water
District of the California Water Service
supplies water to Rolling Hills. There are
two California Water Service water
reservoirs in the city limits.
Services
▪ Public Safety Response. Public safety
services are provided by law enforcement
647
City of Rolling Hills
Rolling Hills General Plan
22
and fire agencies. These agencies include
the Los Angeles County Sheriff and Fire
Departments.
▪ Water Services. These services involve
treating and transporting water to be
used by customers and transporting and
treating wastewater so it can be safely
released into the environment. California
Water Service provides drinking water to
the city.
▪ Energy Delivery. Energy services in
Rolling Hills include electricity and natural
gas delivered through utility lines from
Southern California Edison and Southern
California Gas Company.
Vulnerability Assessment
Results
The Vulnerability Assessment indicates that
the city’s populations, infrastructure, and
services are most vulnerable to wildfire,
extreme heat, and extreme precipitation
events.
Populations
Vulnerable populations such as older adults,
residents with chronic health conditions, and
those with financial trouble are most at risk to
extreme heat and wildfire impacts.
28 percent of the city’s population is over 65
years. Older adults do not adjust as well as
young people to sudden changes in
temperature and are more likely to have
medical conditions that can worsen with
extreme heat (CDC 2017a). Older adults who
are living alone are even more at risk as the
actions necessary to mitigation extreme heat
are more difficult alone. Getting water,
changing clothes, showering, or turning on
the air conditioner may be more difficult for
older adults with physical disabilities and do
not have a partner to assist them. Extreme
heat can be highly dangerous to persons with
chronic health conditions, because very high
temperatures can exacerbate diabetes,
cardiovascular conditions, respiratory
ailments, and other diseases. Some of these
people have weakened immune systems
which can make them more likely to contract
illnesses and vulnerable to human health
hazards. In addition, they may be taking
medications that make the effects of extreme
heat worse (CDC 2017b). While there are not
many households in poverty in the city, those
who are have limited financial resources to
upgrade their homes to have air conditioning
to better resist extreme heat.
Older adults, residents with chronic health
conditions, and those with financial trouble
are the populations most at risk to wildfire
impacts. Older adults are almost three times
more likely to die in a fire than the overall
population (USFA 2017), and typically have
increased mobility or mental health issues.
Therefore, older adults, especially those in
the city living alone, have more difficulties
evacuating to safe areas when there is a
need. Those in Rolling Hills with limited
financial resources are more unlikely to
retrofit their homes to better resist climate-
related hazards such as wildfires. In addition
to direct impacts, indirect impacts such as
poor air quality also creates public health
hazards to the city. Recent California wildfires
in August and September 2020 had areas of
California recording the worst air quality in
the world and highlighted the hazards of
secondary impacts from wildfires, which
could impact the city from fires throughout
the State. Older adults and individuals with
chronic health conditions are likely to be
impacted most by these secondary impacts.
Also, those with limited finances or without
air conditioning would be impacted by
secondary smoke impacts that occur during
local and regional wildfires.
Infrastructure
Access roads, residential structures, and
community facilities and government
buildings are the most vulnerable
648
Climate Change
Safety Element 23
infrastructure to wildfire and extreme
precipitation impacts from climate change.
All city infrastructure is located in a VHFHSZ.
Portuguese Bend Road and Crest Road are
critical for access to and evacuation from
many areas of the city. Wildfires may not
significantly damage the infrastructure, but
they could result in closure or the inability to
travel on them during wildfire events, which
can isolate areas of the city and create severe
health and safety risks. Wildfires are unlikely
to substantially damage trails directly, but
they can force widespread trail closures
which are an important asset to the
community.
The greatest potential impact of life and well-
being would be to residential structures,
which are the primary structures in the city.
In addition, impacts to Rolling Hills
Community Association and City Hall
structures would impact community functions
and government services.
Critical infrastructure most at risk in Rolling
Hills to minor flooding impacts and landslides
from increased storms would be access roads,
bridle trails, electrical utility lines, and water
systems. Because Portuguese Bend Road and
Crest Road are critical for access to and
evacuation from the city, any damage or
closure can effectively isolate areas of the
city, potentially creating severe health and
safety risks. Bridle trails are predominantly
located in canyon areas, which would be
more susceptible to flooding and landslides.
Landslides could impact utilities, as seen in
the existing Flying Triangle Landslide area,
which has moved utility lines above ground in
certain areas due to the continuous
movement of the earth in this area. Due to
the limited accessibility of the city, there is a
medium potential for impacts to access roads
and bridle trails and a low potential impact
for the remaining vulnerable infrastructure.
Services
Energy delivery, specifically electricity
delivery, could be impacted from increased
wildfires. Direct impacts to Southern
California Edison electricity transmission
infrastructure could impact power in the city.
In addition, utility companies have begun
shutting off power to areas to avoid wildfires
during times when weather creates high
wildfire risk. Public safety services could be
strained during wildfire events, which are
expected to increase.
Overall, climate change impacts from wildfire
are projected to have the greatest potential
impact to the city.

Summary
Key Findings
The city is most at risks to impacts from wildfire, extreme heat, and landslide events, which are
all anticipated to increase as a result of climate change impacts. Vulnerable populations such as
older adults and residents with chronic health conditions are most at risk to extreme heat and
wildfire impacts. Access roads and residential structures are also the most vulnerable to wildfire
and landslide impacts from climate change.
The city has a moderate risk for shaking potential from earthquakes.
Flood risks in the city are minimal and limited to natural drainage areas in the canyons.
Vegetation clearing along roadways is a concern and major goal for improving fire response and
evacuation in the city.
Evacuation strategies and education are important to reduce risk from hazards due to the lack
of evacuation routes in the city and the remote development on private roads. The need to
further analyze evacuation routes and access is one of the most recent changes in Safety
Element requirements. A key opportunity for the Safety Element update is to address specific
evacuation needs.
The City has recently adopted a number of planning documents such as the Hazard Mitigation
Plan and Community Wildfire Protection Plan, which seek to reduce the risk of hazards in the
city. An opportunity for the Safety Element update would be to utilize existing
recommendations from the Community Wildfire Protection Plan as implementation tools for the
Safety Element.

Introduction
Section 65302(g) of the California Government Code requires that the General Plan include a Safety
Element for the protection of the community from any unreasonable risks associated with the
effects of seismically induced surface rupture, ground shaking, ground failure, tsunami, seiche, and
dam failure; slope instability leading to mudslides and landslides; subsidence and other geologic
hazards; flooding, wildland and urban fire, and climate change adaptation and resilience. In
addition, Safety Elements are required to address non-hazard specific issues such as peak load water
supply, evacuation routes, and military installations.
This Existing Conditions Report is a comprehensive assessment of natural and man-made hazards
for the City of Rolling Hills. The report serves as the foundation for the Safety Element and includes
detailed Geographic Information System (GIS) hazard mapping and analyses. The following City
plans were also utilized for this report along with existing local data from governmental agencies
and scientific research: Hazard Mitigation Plan, Community Wildfire Protection Plan, and the
existing Safety Element.
Setting
Rolling Hills covers an area of approximately three square-miles on the Palos Verdes peninsula,
approximately 18 miles south of downtown Los Angeles. The topography of the city and peninsula
area is unique in that it rises above the Los Angeles Basin with rolling hills, steep slopes, and
canyons. The city itself is located in the San Pedro Hills. Due to its location near the coast, the area is
cooler and has fewer air quality concerns compared to the nearby Los Angeles Basin. Table 1
summarizes the climatology of the area.

Rolling Hills is a residential community that consists of large parcels and ranch-style homes and has
a sizable older adult 1 population of about 513 (28% of the city’s total population). The city is also an
equestrian community, as many of residents are horse owners or have horses on their property.
Important community demographic data for Rolling Hills is included in Table 2.

Critical Facilities and Infrastructure
Critical facilities are places that provide emergency services or serve people who would be impacted
by an emergency. Examples include hospitals, fire stations, police stations, emergency services
facilities, utility facilities, and communication facilities. Critical facilities can also include the
transportation system and schools. Due to the size and composition of Rolling Hills, most of the
critical facilities that serve the city are located outside of City limits. Critical facilities that serve the
city are shown in Figure 1 and include:

Hazards of Concern
Geologic Hazards
Geologic processes that pose a threat to life, health, property, or infrastructure are considered
geologic hazards. Natural geologic hazards that have the potential to affect Rolling Hills include
seismic hazards, landslides, liquefaction, expansive soils, and weathering. In most cases, these
natural processes cannot be prevented; however, the magnitude of destruction resulting from
natural geologic hazards can be reduced through planning policies and measures.
Landslide Hazards
Landslide activity refers to a wide range of gravity driven downslope earth movement, including
rockslides, rotational slips, mudslides, and shallow debris flows. Geological and geomorphological
conditions such as soil type, soil strength, slope angle, and slope height predispose slopes to failure.
Other factors affecting the susceptibility to slope failure include the amount of precipitation,
vegetation on the slope, groundwater seepage, and human modifications to the slope. Landslides
often result in damage to property and roadways and can cause them to become unsafe due to
displacement of the subsurface.
A majority of the existing development in Rolling Hills is located on hilly terrain and have a greater
potential to experience landslide hazards. Many of the canyons in Rolling Hills exhibit steep slopes
with little vegetation coverage, leaving them susceptible to slope failure. Figure 2 shows the
landslide zones within the City of Rolling Hills, as mapped by the California Geological Survey.
Landslide activity has been well documented in the region. Relicts of landslides and rockslides are
present throughout the City of Rolling Hills. The following major landslides have occurred within and
adjacent to the city. All are within the landslide hazards areas identified in Figure 2:
Portuguese Bend Landslide: Beginning in 2 1956 over approximately 270 acres in Rancho Palos
Verdes
Abalone Cove Landslide: Beginning in 1974 over 80 acres in Rancho Palos Verdes
Klondike Canyon Landslide: Beginning in 1979 over to the south near the coastline
Flying Triangle Landslide: Beginning in 1970s or 1980s over approximately 70 acres in the south
area of the city
The Flying Triangle Landslide continues to impact the southeast portion of the city through impacts
to private roads and requiring above-ground utility lines. This area is relatively unsuitable for
development due to the ongoing changes in topography.
Seismic Hazards
Rolling Hills is located in a seismically active region of southern California. The last major earthquake
in the Los Angeles area was the 5.1 magnitude La Habra earthquake in 2014. Rolling Hills is located
within 50 miles of the Whittier fault, Newport-Inglewood fault, Palos Verdes fault, Malibu Coast
2 “Beginning in” is defined as the first noted event of major rock movement

fault, Cabrillo fault, Santa Monica fault, and Redondo Canyon fault. Analysis of seismic data from the
region indicates that the Whittier and Newport-Inglewood faults may generate a maximum credible
earthquake of magnitude 7.2 and 7.4, respectively (Southern California Earthquake Center 2013).
Figure 3 shows the faults in the vicinity of Rolling Hills.
Typically, seismic shaking and fault rupture are primary hazards as they occur as a direct result of
the interaction between the seismic wave energy and the earth’s surface. Secondary hazards, such
as liquefaction and earthquake-induced landslides, occur as a result of the primary earthquake
hazards. Often, earthquake activity can result in other effects such as building damage/collapse,
infrastructure failure, pipeline breakage, and damage to transportation and communication
facilities. The size of the earthquake and distance from the fault rupture zone typically determine
the severity of these events.
Seismic Shaking
Seismic shaking, or ground shaking, refers to the movement of the earth’s surface resulting from the
energy release by an earthquake. Seismic shaking is typically the primary cause of property damage
resulting from earthquake activity. Seismic shaking has the ability to destroy buildings, roadways,
powerlines, and pipelines. Energy transmitted through the ground has the potential to travel
hundreds of miles and may cause damage in many locations simultaneously. Closer proximity to the
fault rupture area results in stronger shaking in that location.
The amount of ground shaking that occurs in a location is dependent on the magnitude of the
earthquake, the distance from the epicenter, and local soil conditions. The intensity of ground
shaking is related to the peak ground velocity during an earthquake. According to the CGS Map
Sheet 48, the earthquake shaking potential for Rolling Hills is moderate. The intensity of seismic
shaking is measured using the Modified Mercalli scale.
According to the California Geologic Survey, an active fault is one that has experienced surface
movement in the past 11,000 years. The city is located near a number of active faults, including the
Cabrillo Fault within city limits. Table 3 includes a list of nearby faults, their respective distance from
the city, the maximum credible earthquake generated from each fault, and the likelihood of
earthquake occurrence in each case.
Table 3 Faults Located within 50 Miles of Rolling Hills
Fault Name Approximate Distance from Rolling Hills
Whittier 25 miles east
Newport-Inglewood 9 miles east
Palos Verdes <1 mile north
Malibu Coast 20 miles northwest
Cabrillo Located within the City boundaries in the southwest
Santa Monica 20 miles north-northwest
The San Andreas fault is located approximately 80 miles to the east of Rolling Hills. Although the San
Andreas fault is located at a greater distance from the city, seismic shaking originating from
earthquakes occurring along the San Andreas fault poses a threat to the city. Figure 3 identifies the
active and inactive faults located within the city and vicinity.
680
Hazards of Concern
Existing Conditions Report 9
Fault Rupture
Fault Rupture occurs when seismic movement on a fault breaks through the earth’s surface. Hazards
related to fault rupture arise when structures are built near or on top of an active fault. While there
are a number of seismically active faults in the city and region, there are no active faults with the
potential for ground rupture, defined by the Alquist-Priolo Earthquake Fault Zoning Act and
delineated by CGS. Figure 3 shows the designated Alquist-Priolo study zones, the closest of which is
the Newport-Inglewood Fault approximately nine miles northeast of the city.
Liquefaction and Settlement
Liquefaction is a ground failure phenomenon that occurs as a result of a seismic event. Liquefaction
increases water content in surface soils until the soil reaches a semi-liquid state, contributing to a
reduction in support, and ultimately resulting in shifting or subsidence of buildings and utilities.
Ground failure typically occurs when the following conditions exist:
Loose, unconsolidated granular soils
Shallow groundwater
Strong seismic ground shaking
While the Rolling Hills has moderate to high seismic shaking potential, the subsurface soils generally
lack saturated alluvial deposits and thick, granular soils. Figure 4 shows the liquefaction hazard
areas, which are located in the low-lying areas to the east and north, generally surrounding the Los
Angeles Harbor and Harbor Lake. Liquefaction potential for Rolling Hills is low, as shown in Figure 4.
Earthquake Induced Landslides
Ground failure or destabilization of slopes resulting from an earthquake can also occur following
seismic activity in the form of Earthquake-Induced Landslides. Earthquake-induced landslides
typically occur in areas with steep slopes or unstable soil conditions. As discussed above under
Landslide Hazards, the risk of landslide activity in Rolling Hills is high. Much of the city overlies areas
that have been identified as landslide zones by the California Geological Survey. Risk of landslide
activity increases following rainfall events that result in saturated soils. Both shallow and deep
seeded landslides have historically occurred in the city.
Flooding
Rolling Hills participates in the Federal Emergency Management Agency’s (FEMA) National Flood
Insurance Program. According to the FEMA flood maps, the city is not located in a flood hazard area
and currently has a less than 0.2 percent annual chance to be inundated by flood waters as a result
of a storm event (FEMA 2008). Overall, the city is not in any immediate risk from flooding caused by
overflowing water bodies or heavy rains. However, runoff and minor flooding pose a risk if drainage
systems fail along canyon bottoms, where natural drainage leads to.

Dam Inundation
No water storage facilities that the State of California identifies as dams are located in Rolling Hills.
Just outside city limits are three water storage facilities identified as dams, which include:
Palos Verdes Reservoir: Owned by the Metropolitan Water District of Southern California and
located at the southeast corner of Palos Verdes Drive East and Palos Verdes Drive North.
According to the California Department of Water Resources, the reservoir can hold
approximately 1,100 gallons of water and has an extremely high downstream hazard.
10 MG Walteria and 18 MG Walteria: Two reinforced concrete tanks which are owned by the
City of Torrance and located at Crenshaw Boulevard and Crest Road. The tanks can hold 31 and
58 acre-feet (AF) of water respectively.
Senate Bill 92, adopted in 2017, is a new dam safety requirement that requires dam owners to map
the downstream inundation areas for dams governed by the Department of Water Resources.
Figure 5 shows the inundation areas for the nearby water storage facilities. Due to their locations
and the topography of the area, the inundation areas do not enter or affect any portion of the city.
Wildland and Urban Fires
The entire City of Rolling Hills is designated a Very High Fire Hazard Severity Zone (VHFHSZ) by the
California Department of Forestry and Fire Protection (CalFire), as shown in Figure 6. Rolling Hills
terrain is comprised of several large and steep canyons that limit and challenge vegetation
management and present conditions where a fire can quickly travels up and downslope to nearby
homes. Due to the rural nature and large residential lots, many homes are surrounded by
substantial vegetation and dense brush than in more suburban settings. The bridle trails for hikers
and equestrian access also contain dense vegetation and management difficulties, which
contributes to the fire risk of the city. Electrical power lines pose a hazard to starting fires in the city
if lines are not automatically de-energized when knocked down by extreme weather or if the
surrounding vegetation is not adequately managed.
There is a history of fires in the city and the surrounding Palos Verdes Peninsula. Three major fires
have been documented on the Peninsula and in the city in:
1973: almost 1,000 acres burned, and 13 homes destroyed
2005: 212 acres burned near Del Cero Park
2009: 230 acres burned and forced 1,200 residents on the Peninsula to evacuate
For many of the developed residences in the city that are vulnerable to fires, their risk may increase
with the presence of construction techniques that may not meet current wildfire standards. Rolling
Hills Building Code and Los Angeles County Fire Department, under the VHFHSZ standards, require
new development to include more stringent design and material standards for roofing, eaves, and
rafter tails as well as exterior finishes and fire buffer zones. While compliance with these standards
reduces the vulnerability to new structures, existing structures that have not complied with these
standards may be susceptible to undue fire risk.

Hazardous Materials
According to the Department of Toxic Substances Control (DTSC), there are no hazardous waste
sites or facilities in Rolling Hills (DTSC 2020). The city and surrounding area do not contain heavy
industrial uses that would create a hazardous material risk in the event of a spill, release, or natural
disaster.
The city is not located near any major transit routes involving transport of a substantial quantity of
hazardous material through the city. However, the nearby oil refineries (located along Sepulveda
Boulevard approximately six miles northeast) and Port operations (located approximately three
miles to the east) could create air quality impacts if wind patterns and release events occur. Air
quality impacts are discussed in the Open Space and Conservation Element of the Rolling Hills
General Plan.
Emergency Response and Evacuation
Police Response and Crime
The Los Angeles County Sheriff’s Department is contracted with the city to provide police services
and protection to the city. The Lomita Station of the Sheriff’s Department located at 26123
Narbonne Avenue, approximately 1.5 miles northeast of the Portuguese Bend Road entrance, serves
the city.
According to the Lomita Station crimes report from January 1, 2020, through June 30, 2020, Rolling
Hills had three reported crimes (LACSD 2020). The crimes were related to theft, assault, and
burglary. Outside the city limits and in the Lomita District, 433 crimes were reported during this
same period, 71 of which were violent crimes (LACSD 2020). The difference in crimes in the city and
the surrounding area is attributed to the private nature of the City. There are three entrances to the
city, all of which are gated and staffed 24 hours a day. Visitors are required to be on a resident’s
guest list in order to enter city limits. This reduces crime within the city and demand on Los Angeles
County Sheriff’s Department.
Fire Response
The Los Angeles County Fire Department provides emergency operations support to the City. Fire
Station 56, located at 12 Crest Road West, serves the city under Battalion 14, which also serves the
remaining Palos Verdes Peninsula, Lomita, and Catalina Island. Fire response constraints in the city
include ability to access certain homes or areas due to inadequate road widths for fire maneuvering.
One of the major topics of concern related to fire response in the city relates to vegetation clearing
along roadways. Ten-foot clearance on each side of the roadway, especially the limited access
roads, is important for fire response and evacuation during a fire, according to Scott Hale, Assistant
Fire Chief.
Evacuation Strategies and Routes
Because a variety of hazards could affect city residents, it is vital to identify critical routes for
evacuation in the event of a major event. Figure 7 identifies the existing evacuation routes in the
city, which are limited to:
Main Gate at Rolling Hills Road and Palos Verdes Drive North

Crest Gate at Crest Road near Crenshaw Blvd
Eastfield Gate at Eastfield Drive and Palos Verdes Drive East
Crest Road East Gate at the end of Crest Road East
Crest Road East Gate at the end of Crest Road East gate has recently been updated with a motor and
has no guards. This gate is available as an emergency exit to the city during emergencies. The
recently adopted Community Wildfire Protection Plan for the city establishes evacuation strategies
and methodologies for the city, which include:
Using the City’s Block Captains as important coordinators and managers of residents in the 24
City zones 3
Communication goals between the City, emergency responders, Rolling Hills Community
Association, and residents
Details for residents regarding how people get notified during an actual evacuation and the
responsibilities and operations of the Emergency Operations Center
Traffic control responsibilities and levels
Identification of special need residents who may need specific attention and/or assistance
3 The city is divided into 24 zones and each zone has 2-3 block captains to represent the residents within the zone.

Climate Change Vulnerability
In accordance with Senate Bill 379, this section provides a climate change vulnerability assessment
for Rolling Hills, which evaluates the potential impacts of climate change on community assets and
populations. The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report
defines vulnerability as “the propensity or predisposition to be adversely affected.” It adds that
vulnerability “encompasses a variety of concepts and elements including sensitivity or susceptibility
to harm and lack of capacity to cope and adapt” (IPCC, 2013). Understanding the vulnerabilities that
the city may face due to climate change provides a foundation to define future adaptation strategies
for the Safety Element update and other planning efforts in Rolling Hills and the region.
Consistent with the California Adaptation Planning Guide (Cal OES 2020) the assessment is
comprised of the following five elements:
Exposure – the nature and degree to which the community experiences a stress or hazard;
Sensitivity – the aspects of the community (i.e., people, structures, and functions) most affected
by the identified exposures;
Potential Impacts – the nature and degree to which the community is affected by a given
stressor, change, or disturbance;
Adaptive Capacity – the ability to cope with extreme events, to make changes, or to transform
to a greater extent, including the ability to moderate potential damages and to take advantage
of opportunities; and
Vulnerability Scoring – systematic scoring based on potential impacts and adaptive capacity, to
inform major climate vulnerabilities to address adaptation framework strategies.
In addition to City data, Cal-Adapt was used to complete the assessment. Cal-Adapt is an interactive,
online platform developed by the University of California and Berkeley to synthesize climate change
projections and climate impact research for California’s scientists and planners. This assessment
uses Cal-Adapt to study potential future changes in average and extreme temperatures,
precipitation, wildfire, and storms. Cal-Adapt is consistent with State guidance to use the “best
available science” for evaluating climate change vulnerability.
This assessment uses two greenhouse gas (GHG) emissions scenarios included in Cal-Adapts
analysis: Representative Concentration Pathway (RCP) 4.5 and RCP 8.5. RCP 4.5 describes a scenario
in which GHG emissions peak around 2050, decline over the next 30 years and then stabilize by
2100 while RCP 8.5 is the scenario in which GHG emissions continue to rise through the middle of
the century before leveling off around 2100. The climate projections used in this report are from
four models selected by California’s Climate Action Team Research Working Group and the
California Department of Water Resources. These models include:
A warm/dry simulation (HadGEM2-ES)
A cooler/wetter simulation (CNRM-CM5)
An average simulation (CanESM2)

The model that presents a simulation most unlike these three and incorporates 10 other
models, for full representation of possible forecasts (MIROC5)4
The average of the model projections is used in this analysis.
Exposure
Climate change is a global phenomenon that has the potential to adversely affect local health,
natural resources, infrastructure, emergency response, and many other facets of society. Projected
changes to climate are dependent on location. According to Cal-Adapt, climate change could lead to
increasing temperatures, temperature extremes, and changes in precipitation patterns in Rolling
Hills. These conditions could lead to exposure associated with extreme heat, drought, wildfires, and
extreme storms in the region. The climate hazards of concern for Rolling Hills addressed in this
analysis are:
Extreme Heat
Storms and Extreme Weather
Drought
Wildfire
Extreme Heat
Figure 8 below shows observed and projected annual average maximum temperature in Rolling
Hills. As shown in Figure 8, average temperatures in the city and region have increased, which is a
trend at both the local scale and the global scale. Compared to 1990, annual average maximum
temperatures in Rolling Hills are expected to rise between 1.8°F and 6.6°F by the end of the century,
depending on the GHG emissions scenario (CEC 2020).
4 There were 10 California GCM models that were ranked from 1-10 by California’s Climate Action Team Research Working Group and the
California Department of Water Resources for different temperature and precipitation factors. The models ranged from the “warm/dry”
model which had all metrics closest to 1 to the “cool/wet” model which had all metrics closest to 10. The MIROC5 displays a pattern of
ranking that is most unlike the other 3 models and therefore, is included to represent the full spread of all 10 model simulations.

Figure 8 Historical and Projected Annual Average Maximum Temperature in Rolling
Hills 5
Extreme heat is a period when temperatures are abnormally high relative to the normal
temperature range. There are generally three types of extreme heat events:
Extreme Heat Days: a day during which the maximum temperature surpasses 98 percent of all
historic high temperatures for the area, using the time between April and October from 1950 to
2005 as the baseline
Warm Nights: a day between April to October when the minimum temperature exceeds 98
percent of all historic minimum daytime temperatures observed between 1950 to 2005
Extreme Heat Waves: a successive series of extreme heat days and warm nights where extreme
temperatures do not abate. While no universally accepted minimum length of time for a
heatwave event exists, Cal-Adapt considers four, successive extreme heat days and warm nights
to be the minimum threshold for an extreme heatwave
Extreme heat events will feel different from region to region since different areas have different
historic high temperatures. For example, an extreme heat day on the coast will feel different than
an extreme heat day in the desert. According to Cal-Adapt, an extreme heat day in Rolling Hills
involves a temperature that exceeds 91.7 ̊F (CEC 2020).
Historically (between 1950 and 2005), Rolling Hills experienced an average four extreme heat days
per year, typically occurring between April and October. As a result of rising average temperatures
and climate change as discussed above, the city is projected to experience between 8 and 14
extreme heat days annually from 2030 to 2099 under medium and high emissions projections (CEC
5 Chart shows annual average maximum temperature for Rolling Hills (Grid Cell 33.78125, -118.34375) under RCP 8.5 (emissions continue

2020). As shown in Figure 9, the number of extreme heat days each year is variable, but overall they
are increasing from historic averages and would continue to increase through the century.
Figure 9 Number of Extreme Heat Days by Year in Rolling Hills 6
Extreme heat waves are defined as four or more consecutive extreme heat days. These events have
been historically infrequent in Rolling Hills, with the historical average being 0.3 heat waves
annually. The city is expected to experience a minor increase in heat wave frequency as the climate
changes. Between 2030 and 2099, the city is projected to experience between 0.4 and 1.1 heat
waves per year (CEC 2020).
Drought
Droughts are somewhat frequent in California, and currently approximately 42 percent of
California’s population are in a drought, or in an abnormally dry area (NIDIS 2020). Changes in
weather patterns resulting in increases in global average temperatures are already causing
decreases in snowpack, which provides as much as a third of California’s water supply (DWR 2019).
According to the U.S. Drought Monitor, Los Angeles County and Rolling Hills are not currently
experiencing drought conditions based on this mapping (National Drought Mitigation Center 2020).
Southern California is not currently considered to be in a drought condition, while other parts of the
State (northern California and the Sierra Nevada mountain range) are experiencing moderate
drought conditions due to lower than average precipitation.
The projected changes in annual precipitation for Rolling Hills are shown in Table 4. Under both the
medium and high GHG emissions scenarios, Rolling Hills is not expected to experience substantial
changes in average precipitation. However, the city would experience increased variability in
precipitation. The city’s minimum annual precipitation would decrease while the maximum annual
precipitation would increase under both emissions scenarios.

While overall precipitation levels are expected to change substantially in the city, a drought may
occur when conditions in areas where water sources are located experience drought conditions,
even though the local region does not. Rolling Hills obtains its water from the Palos Verdes District
of the California Water Service. Water supply from the District to this area is purchased from the
Metropolitan Water District of Southern California (MWD), which imports its water from the
Colorado River and State Water Project from northern California.
Recent research suggests that extended drought occurrence could become more pervasive in future
decades (CEC 2020). An extended drought scenario is predicted for all of California from 2051 to
2070 under a climate model using business as usual conditions. The extended drought scenario is
based on the average annual precipitation over 20 years. This average value equates to 78 percent
of the historic median annual precipitation averaged for the North Coast and Sierra California
Climate Tracker regions. Overall precipitation levels in the city are not expected to be significantly
impacted. However, variability in precipitation and drought conditions in other areas of the state
could impact water supply.
Wildfire
Wildfire hazards to the city are widespread and discussed above under Hazards of Concern.
Wildfires in the city are influenced by a range of factors including droughts, severe winds, wildfire
fuel (i.e. dry vegetation), and previous wildfire suppression activity. Climate change is expected to
exacerbate wildfire risk by creating hotter and drier landscapes, as discussed above under Extreme
Heat, which are more susceptible to burning.
Cal-Adapt provides projections for annual mean hectares burned. This projection only accounts for
areas that could experience wildfire events. Los Angeles County wildfire occurrence is anticipated to
increase under all emissions and population scenarios from historic averages (CEC 2020). In 2020
alone, California has experienced six of the 20 largest fires in modern history and as of the date of
this report, over three million acres of land have burned. These fires arose during extreme fire
weather conditions and record-breaking heat waves across California. The observed frequency of
autumn days with extreme fire weather, which are associated with extreme autumn wildfires, has
more than doubled in California since the early 1980s (Goss et al. 2020). Due to the increases in
factors that contribute to wildfires (variability in precipitation, hotter and dryer landscapes) and
because the city is in a VHFZSZ, it is expected to see an increase in wildfire hazards due to climate
change.
Storms and Extreme Weather
A warming climate is likely to influence the frequency and intensity of storms. Both increased
temperatures and altered precipitation patterns can lead to altered seasons and intense rainstorms
in Rolling Hills. As depicted in Figure 10, there is a high degree of variability in these extreme
695
City of Rolling Hills
Rolling Hills General Plan Safety Element
24
precipitation event projections, with some models projecting little to no change while others project
increased intensity (CEC 2020) These projections further vary depending on the return period7
selected. Increasing intensity of rainstorms could result in more flooding, which could adversely
affect human safety in Rolling Hills. During years of intense levels of precipitation and storms, the
city could also see an increase in the number of landslides or make landslides greater than usual.
Due to the number of landslide hazard zones in the city, as shown in 2, Rolling Hills may see an
increase in landslides due to changes in precipitation from climate change.
Figure 10 Changes in Intensity of Extreme Precipitation Events in Rolling Hills8
Community Sensitivity
As climate change occurs, communities will be affected to varying degrees depending on the
exposure levels as well as how sensitive the communities are to impacts. Virtually all people and
assets in a community will be affected by climate change in some way. However, it is not usually
feasible to assess the vulnerability of every population group or every asset in the community. The
sensitivity of a community depends on the aspects of the community (i.e., specific populations and
assets) most affected by the identified exposures, and how prevalent they are in the community.
As described in the Exposure section above, the most likely primary impacts of climate change that
Rolling Hills may experience include extreme heat, increases in wildfire risk and prevalence, and
drought conditions affecting water supply. This section of the Vulnerability Analysis identifies the
7 Average time between extreme events (e.g., “1 in 100-year event”)

sensitive areas of the Rolling Hills community from the demographic and community facility
information in the Introduction section above and is based on the following categories:
Populations
Infrastructure
Buildings and Facilities
Services
Populations
The vulnerability assessment considers the following population groups that may be
disproportionally harmed by the impacts of climate change in Rolling Hills.
Children: Approximately 6.6 percent of the total population in Rolling Hills are ten years old or
younger.
Persons in poverty: This is identified for people living in households with an income below the
poverty limit, which is $26,200 for a household of four people. There are approximately 26 people in
Rolling Hills who live in poverty, or approximately 1.6 percent of the total population for whom
poverty status can be determined.
Persons with chronic health conditions: These are people who have a long-term or permanent
health condition that can create regular challenges in their day-to-day lives. These health problems
include obesity, cancer, heart disease, and arthritis. In addition, those with any kind of disability,
including mobility challenges, hearing, or vision impairments, behavioral disabilities, and challenges
living independently or taking care of themselves. Approximately 11.5 percent of the population
have identified having a disability.
Renters: These are people who live in homes that they (or the head of their household) do not own.
Approximately 24 housing units, or 4 percent of the housing units in Rolling Hills, are renter-
occupied.
Older adults: These are persons 65 years or older are more at risk for climate change impacts,
especially those living alone. 28 percent of the population of Rolling Hills are over 65 years, and 15
percent of those over 65 years live alone.
Limited English proficiency: Approximately three percent of households have identified being
limited English-speaking. Of those, a majority spoke Asian and Pacific Island languages and Spanish.
Infrastructure
The vulnerability assessment considers the following infrastructure in the city that was identified as
bring sensitive to climate change impacts.
Access Roads: These roadways are one of a few, or the only, ways in and out of some communities
or neighborhoods. The single or limited number of entry and exit points does not make the road
itself more vulnerable than other roads, but loss of these roadways can effectively cut off large
numbers of people from other areas in the Palos Verdes Peninsula and the rest of Los Angeles
County. Portuguese Bend Road and Crest Road are the primary access roads into and out of the city.
Bridle Trails: Throughout the community are over 25 miles of trails available to city residents and
non-city residents who obtain permits. The trails are maintained by the Rolling Hills Community
Association and located primarily in canyon areas.

Electrical Substations: Electrical substations are facilities that convert electricity from one voltage to
another, making it suitable for long-distance transmission or for use by homes, businesses, and
other electrical customers. There are no electrical substations located within city limits, but three
are located near the city in Rancho Palos Verdes and owned/operated by Southern California
Edison.
Electrical Utility Lines: These lines transmit and deliver electricity from Southern California Edison to
the city. The city has both underground and overhead electric utility lines.
Natural Gas Transmission Pipelines: Natural gas pipelines carry large volumes of natural gas
between communities. There are no transmissions lines in the city. One transmission line ends at
the intersection of Rolling Hills Road and Palos Verdes Drive, adjacent to city limits.
Water Reservoirs and System: The system that stores and supplies drinking water for residents.
Palos Verdes Water District of the California Water Service supplies water to Rolling Hills. There are
two California Water Service water reservoirs within the city limits.
Building and Facilities
Residential Structures: Residential structures in Rolling Hills consist of single-family dwellings and
are the main type of building in the city.
Community Facilities and Government Buildings: Community and government facilities are public
properties and are important to the residents as well as the operation of the city. Rolling Hills is a
private community. Therefore, community and government facilities are available only to its
residents, which are the Rolling Hills Community Association and City Hall.
Community Parks: Storm Hill is an open space area owned by the City which is utilized for
equestrian purposes. The City also has two equestrian rings and tennis courts.
Schools: Rancho Del Mar High School is the only school in the city
Public Safety Facilities: Public safety facilities include sheriff and fire buildings. Los Angeles County
Fire Station 56 is located within the city. The Lomita Station of the Los Angeles County Sheriff serves
the city but is not located within the city limits.
Services
Public Safety Response: Public safety services are provided by law enforcement and fire agencies.
These agencies include the Los Angeles County Sheriff and Fire Departments.
Water Services: These services involve treating and transporting water to be used by customers and
transporting and treating wastewater so it can be safely released into the environment. California
Water Service provides drinking water to the city.
Energy delivery: Energy services in Rolling Hills include electricity and natural gas delivered through
utility lines from Southern California Edison and Southern California Gas Company.
Potential Impacts
Impact vulnerability is the nature and degree to which the community is affected by a given
stressor, change, or disturbance. As climate change continues to progress, increased stress to
vulnerable community populations, infrastructure, building and facilities, and services are expected.
As described in the Exposure section above, the most likely primary impacts of climate change
698
Climate Change Vulnerability
Existing Conditions Report 27
Rolling Hills may experience include extreme heat, wildfire, and drought conditions impacting water
supply. The vulnerability of Rolling Hills to the primary exposures of climate change is discussed
below. The vulnerability scores discussed in the Vulnerability Scoring section are based on the
potential impact analysis below. Each of the vulnerable areas in the city were given a low, medium,
or high vulnerability to the potential impacts, based off the descriptions in the Vulnerability Scoring
section.
Temperature and Extreme Heat
As describe in the Exposure section above, Rolling Hills may experience a variety of impacts from
climate change, which include an increase of average annual maximum temperature between 1.8°F
and 6.6°F by the end of the century (CEC 2020) This increase in temperature may result in changes
in seasonal patterns, an increase in heat waves, drought, and potentially increased storm frequency
and intensity. Rolling Hills is expected to experience between 8 and 14 extreme heat days annually.
Overall quality of life in the city would be impacted during extreme heat events as outdoor activities
would be limited and overall comfort reduced.
The potential direct and indirect impacts to community populations, infrastructure, building and
facilities, and services are described below.
Populations
The vulnerable populations discussed above that are most at risk to extreme heat impacts from
climate change are older adults, individuals with chronic conditions such as heart and lung disease,
diabetes, and mental illnesses, children, and those who are economically disadvantaged.
The primary vulnerable population to temperature increases and extreme heat in Rolling Hills is
older adults, as 28 percent of the city’s population is over 65 years. Older adults do not adjust as
well as young people to sudden changes in temperature and are more likely to have medical
conditions that can worsen with extreme heat (CDC 2017a). Older adults who are living along are
even more at risk as the actions necessary to mitigation extreme heat are more difficult alone.
Getting water, changing clothes, showering, or turning on the air conditioner may be more difficult
for older adults with physical disabilities and do not have a living partner to assist them. Children are
also at risk to extreme heat impacts, especially those under the age of four, due to their less-
developed physiology, immune system, and dependence on others (CDC 2019).
Extreme heat can be highly dangerous to persons with chronic health conditions, because very high
temperatures can exacerbate diabetes, cardiovascular conditions, respiratory ailments, and other
diseases. Some of these people have weakened immune systems which can make them more likely
to contract illnesses and vulnerable to human health hazards. In addition, they may be taking
medications that make the effects of extreme heat worse (CDC 2017b).
While there are not many households in poverty in the city, those who are have limited financial
resources to upgrade their homes and use air conditioning to better resist extreme heat.
Each of the vulnerable populations has a high potential impact from extreme heat.
Infrastructure
Extreme heat and temperature increase due to climate change would not directly impact
infrastructure in Rolling Hills. Indirect impacts on electrical substations and utility lines could occur
from increased use of the system from running air conditioners, leading to power outages in the
699
City of Rolling Hills
Rolling Hills General Plan Safety Element
28
city. In addition, indirect impacts to the water system through increased evaporation or water use
could occur. These infrastructure facilities would have a medium potential impact from extreme
heat.
Building and Facilities
Extreme heat and temperature increase due to climate change
would not directly affect buildings or facilities in Rolling Hills. Extreme heat and temperature
increases could impact the ability for residents to enjoy community park facilities. In addition,
extreme heat could create wildfire conditions which could indirectly impact all buildings and
facilities within the city. Overall, there is a low potential impact from extreme heat to City buildings
and facilities.
Services
The important services discussed above that are most at risk to extreme heat impacts from climate
change are water services and energy delivery.
High temperatures would contribute to a reduced water supply. For instance, higher temperatures
will melt the Sierra snowpack earlier and drive the snowline higher. In addition to a reduction in
precipitation falling as snow, higher temperatures would result in less snowpack to supply water to
California users (CNRA 2009). Increased temperatures could therefore result in decreased potable
water supply for the city which relies on imported water from the State Water Project and Colorado
River water (Cal Water 2016). Therefore, there is a medium potential impact for high temperatures
and drought on the city.
Long periods of intense heat may result in increased use of electricity for home cooling purposes
that could tax the overall electrical system and result in electricity restrictions or blackouts. During
extreme heat events in August 2020, California had its first rolling blackouts since 2001. Therefore,
the city will experience greater potential for power outages due to climate change and has a
medium potential impact.
Storms/Extreme Weather and Drought
As mentioned in the Exposure section above, the storm and extreme weather projections for Rolling
Hills show variability, with some models projecting little to no change while others project increased
intensity. This could result in impacts to community populations, infrastructure, building and
facilities, and services, particularly related to temporary flooding and landslides which can be
triggered from intense rainfall events. The city currently has a less than 0.2 percent annual chance
to be inundated by flood waters as a result of a storm event (FEMA 2008). Increases in intense
precipitation could result in slope failures in landslide prone areas shown in Figure 2, including the
existing Flying Triangle Landslide area.
As discussed in the Exposure section above, Rolling Hills is not expected to experience substantial
changes in average precipitation. However, the city receives its water from the Colorado River and
State Water Project from northern California, and extended drought scenario is predicted for these
areas, which equates to 78 percent of the historic median annual precipitation. Therefore, areas
that supply water to Rolling Hills and other jurisdictions are expected to see a 22 percent reduction
of their water supply, which could reduce the amount of potable water available for delivery to the
city.
700
Climate Change Vulnerability
Existing Conditions Report 29
Populations
The city’s older adults and those with chronic health conditions are the populations in Rolling Hills
that are more at risk of injury and or death resulting from minor floods or fallen trees created by
more intense storms induced by climate change. Indirect impacts to these populations from impacts
to the transportation system could include reduced access to emergency response and health
centers for those who need consistent medical care. There is a medium potential for impacts to
these vulnerable populations.
Infrastructure
Critical infrastructure most at risk in Rolling Hills to minor flooding impacts and landslides from
increased storms would be access roads, bridle trails, electrical utility lines, and water systems.
Because Portuguese Bend Road and Crest Road are critical for access to and evacuation from the
city, any damage or closure can effectively isolate areas of the city, potentially creating severe
health and safety risks. Bridle trails are predominantly located in canyon areas, which would be
more susceptible to flooding and landslides. Landslides could impact utilities, as seen in the existing
Flying Triangle Landslide area, which has moved utility lines above ground in certain areas due to
the continuous movement of the earth in this area. Due to the limited accessibility of the city, there
is a medium potential impact for access roads and bridle trails and a low potential impact for the
remaining vulnerable infrastructure.
Building and Facilities
Buildings and facilities most at risk from impacts of more intense storms would be residential
structures and community parks. The proper functioning residential septic systems could be
impacted by more intense rainfall and minor flooding. In addition, landslides could be triggered as
indirect impacts from more intense storms and rainfall. Residential structures located in landslide
hazard areas shown in Figure 2 could be impacted. In addition, the Storm Hill open space area is an
important facility in the city and is also located in a landslide area. Due to the variability in weather
projections, there is a low potential impact for buildings and facilities.
Services
Increased storm intensity and drought conditions from climate change could impact public safety
response, energy delivery and water services in the city. Emergency response systems could be
impacted from flooding or landslides within or outside of city limits, which could restrict the ability
for emergency response to access the city and impact response times.
More intense storms could adversely affect electricity delivery from Southern California Edison from
power outages caused by downed electrical utility lines from wind of landslide events. In addition,
water service from the California Water Service Palos Verdes District could be affected by increased
drought conditions throughout the state. There is a medium potential impact for buildings and
facilities.
Wildfire
Wildfires in Los Angeles County are projected to increase under all emissions and population
scenarios. As discussed in the Exposure section above, wildfire hazards to the city are widespread
and wildfire conditions are expected to be exacerbated by a range of factors including droughts,
701
City of Rolling Hills
Rolling Hills General Plan Safety Element
30
more severe winds, wildfire fuel (i.e., dry vegetation), and hotter and drier landscapes from
increased temperatures and extreme heat.
Populations
The vulnerable populations discussed above that are most at risk to increases in wildfire from
climate change are older adults, persons in poverty, and persons with chronic health conditions.
Older adults are almost three times more likely to die in a fire than the overall population (USFA
2017), and typically have increased mobility issues or mental health. Therefore, older adults,
especially those in the city living alone, have more difficulties evacuating to safe areas when there is
a need. Those in Rolling Hills with limited financial resources are more unlikely to retrofit their
homes to better resist climate-related hazards such as wildfires.
In addition to direct impacts, indirect impacts such as poor air quality also creates public health
hazards to the city. Recent California wildfires in August and September 2020 had areas of California
recording the worst air quality in the world and highlighted the hazards of secondary impacts from
wildfires, which could impact the city from fires throughout the State. Older adults and individuals
with chronic health conditions are likely to be impacted most by these secondary impacts. Also,
those with limited finances or without air conditioning would be impacted by secondary smoke
impacts that occur during local and regional wildfires. There is a high potential for wildfire impacts
on the vulnerable populations.
Infrastructure
All city infrastructure is located in a VHFHSZ. The critical infrastructure most at risk to increased
wildfire impacts would be access roads, bridle trails, above ground electrical utility lines, and water
systems. Portuguese Bend Road and Crest Road are critical for access to and evacuation from many
areas of the city. Wildfires may not significantly damage the infrastructure, but they could result in
closure or the inability to travel on them during wildfire events, which can isolate areas of the city
and create severe health and safety risks. There is a high potential for impacts to access roads from
wildfires.
Wildfires are unlikely to substantially damage trails directly, but they can force widespread trail
closures which are an important asset to the community. Above ground electrical lines are also at
risk from wildfires and could impact electricity services to residents in Rolling Hills. Water systems
could be directly affected by wildfires in addition to indirect impacts from water use from
firefighting activities and peak load water supply in remote portions of the city. There is a medium
potential for impact to these infrastructures.
Building and Facilities
As discussed under Hazards of Concern section, all of Rolling Hills is designated a VHFHSZ.
Therefore, all buildings and facilities within the city are at risk of increased wildfires caused by
climate change. The greatest potential impact of life and well-being would be to residential
structures, which are the primary structures in the city. In addition, impacts to Rolling Hills
Community Association and City Hall structures would impact community functions and government
services. There is a high potential for impact to buildings and facilities from wildfire.
702
Climate Change Vulnerability
Existing Conditions Report 31
Services
Energy delivery, specifically electricity delivery, could be impacted from increased wildfires. Direct
impacts to Southern California Edison electricity transmission infrastructure could impact power in
the city. In addition, utility companies have begun shutting off power to areas to avoid wildfires
during times when weather creates high wildfire risk. In addition, public safety services could be
strained during wildfire events, which are expected to increase. There is a medium potential for
impacts to services in the city from wildfire.
Adaptive Capacity
Adaptive capacity is the current ability to cope with climate change impacts to community
populations and assets (Cal OES 2020). Specifically, adaptative capacity is the ability to mitigate the
potential impacts and damages or take advantage of the opportunities from climate change. Many
communities have adaptive capacity in the form of policies, plans, programs, or institutions. Rolling
Hills has actively taken steps to increase the city’s adaptive capacity, which include preparing a
community wildfire protection plan, hazard mitigation plan, undergrounding utility lines, and
adopting strict new building standards. Table 5 lists various guiding documents, projects, plans, and
policies that have an underlying emphasis on adaptive capacity in the city.

Rolling Hills has a number of plans and policies specific to wildfire hazards. The city’s recently
adopted the Community Wildfire Protection Plan that includes fire mitigation strategies and
evacuations strategies specific for the city. In addition, the Hazard Mitigation Plan provides an
analysis of historical hazards, a local hazard assessment, hazard impacts on the community, and
recommended mitigation strategies. The City requires the undergrounding of utility lines with
specific home upgrades and has a reimbursement program for utility pole replacement. In addition,
building code requirements for development within VHFHSZ, such as Class A roofing, would help
reduce wildfire impacts to structures in the city.

The Rolling Hills Building and Zoning Codes include controls on development on steep slopes and
canyon bottoms. In addition, development requires proof of stability of the property through
geotechnical reports and only a percentage of each lot can be disturbed.
The Palos Verdes Water District’s Urban Water Management Plan (UWMP) provides water supply
and demand projections and includes a climate change analysis. The 2015 UWMP projected that
water supply reductions to the District due to climate change would be small for through the end of
the century. In addition, the UWMP includes a water shortage contingency plan and demand
reduction measures in the event water supply to the District is impacts from drought due to climate
change.
In addition, the city’s population has a high degree of adaptive capacity due to the high levels of
home ownership, low poverty levels, and high average income levels. These characteristics improve
resident’s ability to upgrade their homes and come back from potential impacts to their property
from wildfire and extreme storm events.
Vulnerability Scoring
Vulnerability scores are based on the combination of potential impacts from climate hazards and
adaptive capacity in order to identify the climate vulnerabilities in the city to address with additional
adaptation strategies. A vulnerability score was determined for each sensitivity area based on the
potential impacts and adaptive capacity from climate change in the city. Vulnerability was accessed
on a scale from 1 to 5:
V-1: Minimal Vulnerability
V-2: Low Vulnerability
V-3: Moderate Vulnerability
V-4: High
V-5: Severe
Cal OES recommended the following scoring rubric to determine the vulnerability score for the
potential impacts and adaptive capacity.
Low Potential Impact: Impact is unlikely based on projected exposure; would
result in minor consequences to public health, safety, and/or other metrics of concern
Medium Potential Impact: Impact is somewhat likely based on projected exposure; would
result in some consequences to public health, safety, and/or other metrics of concern
High Potential Impact: Impact is highly likely based on projected exposure; would result in
substantial consequences to public health, safety, and/or other metrics of concern
Low Adaptive Capacity: The population or asset lacks capacity to manage climate impact; major
changes would be required
Medium Adaptive Capacity: The population or asset has some capacity to manage climate
impact; some changes would be required
High Adaptive Capacity: The population or asset has high capacity to manage climate impact;
minimal to no changes are required
Table 6 shows how the final vulnerability score was determined. To summarize, potential impacts
from climate change that are highly likely to occur in the city based on projected exposure would
704
Climate Change Vulnerability
Existing Conditions Report 33
create a high vulnerability score. However, if the city has a high adaptive capacity to manage the
impact, then the overall vulnerability score would be reduced.
Table 6 Vulnerability Score Matrix Potential Impacts High V-3 V-4 V-5
Medium V-2 V-3 V-4
Low V-1 V-2 V-3
High Medium Low
Adaptive Capacity
The vulnerability scoring for the identified population and assets for each climate impact is included
below in Table 7 and based on Cal OES California Adaptation Planning Guide. For those populations
and assets that are not anticipated to be impacted directly or indirectly from the identified climate
impacts, no vulnerabilty score or color is provided. For example, drought impacts on children were
determined to not be a threat in Rolling Hills.
For the purposes of this vulnerability assessment, a score of V-4 or V-5 is considered significant.
Populations and assets that score at least a V-4 for one or more exposures are considered
substantially vulnerable. As shown in Table 7, the potential impacts from climate change the city’s
population and assets are most vulnerable to are wildfire, extreme heat, and landslides. Vulnerable
populations such as older adults, residents with chronic health conditions, and those with financial
trouble are most at risk to extreme heat and wildfire impacts and are substantially vulnerable to
climate change impacts in the city. Access roads and residential structures are also the most
vulnerable to wildfire and landslide impacts from climate change. Overall, climate change impacts
on wildfire are the greatest potential impact to the city. While the City has adopted a significant
number of adaptation strategies related to wildfire impacts, because they were recently adopted
and some of the strategies were included as recommendations, it will be important to determine
and monitor if implementation is occurring and which recommendations should be included in the
Safety Element update.
This vulnerability assessment and the results in Table 7 will be used to identify specific policies and
implementable strategies for adapting to climate change in the Safety Element, thus making the
Rolling Hills community more resilient.

Summary of Issues and Opportunities
Existing hazards of concern in the city that should be a major focus of the Safety Element update
include landslide and wildfire hazards. In addition, emergency response and evacuation should be a
focus due to the city’s accessibility issues. Climate change is expected to increase potential hazards
the city experiences. From the vulnerability analysis, the city is most vulnerable to wildfire impacts,
extreme heat, and landslides impacts from climate change.
Hazards of Concern and Community Sensitivity
While there are a number of hazards that could impacts the city, the following are hazards of
concern that pose the greatest challenge to the city.
Wildfire
The greatest hazard of concern for the city is wildfire as the entire city limits are within a VHFHSZ
and the city contains many remote areas and limited evacuation routes. Some existing residential
and accessory structures are not built to current standards that apply to VHFHSZ and as a result
many of these structures may require mitigation and retrofit to reduce this potential threat. The
area’s most vulnerable to wildfire impacts include older adults, persons with chronic health
conditions, residential structures, government and community buildings, and access roads.
Landslides
Landslides are also a major concern for the city, whether they are earthquake induced, induced
from high precipitation events, or occur due to the underlying soil conditions. Existing landslides are
impacting the southern portion of the city. Climate change has the potential to create more
landslide events if Rolling Hills experiences more intense storms and precipitation events. The area’s
most vulnerable to landslide impacts include access roads, residential structures, and community
parks.
Extreme Heat
The city is expected to see increases in the number and length of extreme heat days and events due
to climate change, which could impact vulnerable people in the city and lead to increased wildfire
risks. The area’s most vulnerable to extreme heat impacts from climate change include older adults,
persons with chronic health conditions, and the energy system.
Opportunities
The need to further analyze evacuation routes and access is one of the most recent changes in
Safety Element requirements. These new requirements focus on the identification of areas where
routes are lacking or inadequate. A key opportunity for the Safety Element update is address
specific evacuation needs.
The City has recently adopted a number of planning documents, such as the Hazard Mitigation Plan
and Community Wildfire Protection Plan, that seek to reduce the risk of hazards in the city. Many of
the strategies included in these documents are recommendations and are used for educational
purposes. An opportunity for the Safety Element update would be to include the recommendations
708
Summary of Issues and Opportunities
Existing Conditions Report 37
as implementation tools for the Safety Element and to conduct outreach with the community to
determine if community preparedness is occurring.
The California Legislature recently adopted Senate Bill 182 (SB 182) and is awaiting Governor
approval. SB 182 would require the Safety Element to include a comprehensive retrofit strategy as
necessary to reduce the risk of property loss and damage during wildfires. Additionally, in order to
reduce development pressures in the VHFHSZ through the Regional Housing Needs Allocation
process, SB 182 requires a lower proportion of state housing allocation to jurisdictions that meet
specified conditions. The City should monitor and incorporate these elements as necessary.

Good morning John,
If the Gabrielino Tongva Indians of California Tribal Council wish to consult under SB 18 or AB 52
concerning these proposed Element Updates please contact John Signo, AICP, at the City of
Rolling Hills (jsigno@cityofrh.net - City Of Rolling Hills – City Hall 2; Portuguese Bend Road,
Rolling Hills CA 90274; O: 310.377.1521 | F: 310.377.7288). Alternatively, feel free to contact
either Kellie or myself and we will coordinate with the City.
Please let Kellie or me know if you have any questions or concerns, and we will be happy to
help.
Thank you,
Richard
We are in receipt of your 21330 City of Rolling Hills Housing & Safety Element Project SB 18/AB 52
Consult Request. Thank you for reaching out.
After conferring with Tribal Chair Dorame (the Most Likely Descendent), this property is highly culturally
sensitive to the Gabrielino Tongva Indians of California (GTIOC) as it resides near one of our villages. The
Gabrielino Tongva Indians of California request an AB52 and SB18 consultation for this project.
There are a minimum of 7 identified sties near the project area; LAN 110, LAN 191, LAN 276, LAN277,
LAN278, LAN 279, LAN 280 (LAN 275 borders your project area).
The concern with all of these sites is that they are significant evidence of the existence of a village site
and the area may still yield evidence of buried deposits. Artifacts unearthed in previous projects
included obsidian projectiles, sandstone bowls, cog stones and more importantly, human remains.
The Gabrielino Tongva Indians of California tribe is deeply concerned with any ground disturbances in
your project area and this project will need a monitor from the Gabrielino Tongva Indians of California
for only ground disturbances.
Attached are our treatment plans for your project site.
Please let us know what your next steps are and how we may assist you.
Take good care and happy new year,
Christina

Consult Request
Dear Christina Conley,
The City of Rolling Hills (City) is commencing its Senate Bill (SB) 18 and
Assembly Bill (AB) 52 consultation processes for the Housing and Safety Element
Updates Project (Project). Pursuant to Government Codes §65352.3 and §65352.4
SB 18 require local governments to consult with California Native American
tribes identified by the Native American Heritage Commission (NAHC) for the
purpose of avoiding, protecting, and/or mitigating impacts to cultural places
when creating or amending General Plans, Specific Plans and Community Plans.
Additionally, AB 52 (Public Resources Codes §21080.3.1 and §21080.3.2) requires
public agencies to consult with California Native American tribes identified by
the NAHC for the purpose of avoiding, protecting, and/or mitigating impacts to
tribal cultural resources (TCRs) as defined, for California Environmental Quality
Act (CEQA) projects. This letter is being provided to you because your Tribe, the
Gabrielino Tongva Indians of California Tribal Council, was listed on the NAHC
directory as an individual or group who may have additional knowledge
pertaining to tribal cultural resources within this geographic area.
The Project consists of a Housing Element Update of the City of Rolling Hills
General Plan and an update to the City’s Safety Element to address various
natural and human-caused hazards the City has dealt with including
earthquakes, wildfires, droughts, and land movement.
718
4
The Housing Element and Safety Element Updates are policy updates only, and
no specific developments are proposed at this time. A description of each of the
updates is provided below.
Housing Element Update
The City’s Housing Element serves as an integrated part of the General Plan, and
is subject to detailed statutory requirements, including a requirement to be
updated every eight years, and mandatory review by the California Department
of Housing and Community Development (HCD). The City is currently adopting
their 6thcycle Housing Element Update (HEU). The City’s Regional Housing
Needs Allocation (RHNA) for this 6th cycle, is 45 units which the City determined
can be met with existing approved developments, the underutilized Rancho Del
Mar school site, and Accessory Dwelling Units (ADUs). Therefore, the HEU, is a
policy document; no actual development nor rezoning of parcels is included as
part of the approval.
Safety Element Update
The Safety Element Update (SEU) provides the City goals, policies, and actions to
minimize the hazards to safety in and around the City. The SEU evaluates
natural and human-caused safety hazards that affect existing and future
development and provides guidelines for protecting the community from harm.
The SEU describes existing and potential future conditions and sets policies for
improved public safety. The goal of the SEU is to reduce the risk of injury, death,
property loss, and other hardships to acceptable levels.
As part of the proposed updates the City has requested a Sacred Lands File (SLF)
search by the NAHC. The result of the SLF search conducted through the NAHC
was negative for the Project site. The City of Rolling Hills is a rural, equestrian
residential community, consisting entirely of large lot residential parcels of one
acre or more (Figure 1). The community encompasses 2.99 square miles of land
(approximately 1,910 acres) on the Palos Verdes Peninsula in the County of Los
Angeles.
Please consider this letter notification and preliminary Project information as the
initiation of the SB 18 and AB 52 requests for consultation. Pursuant to PRC
21080.3.1(d), the Gabrielino Tongva Indians of California Tribal Council have 30
days upon receipt of this letter to provide a request for AB 52 consultation on the
Project. Pursuant to GC 65352.3, the Gabrielino Tongva Indians of California
Tribal Council have 90 days upon receipt of this letter to provide a request for SB
18 consultation. Due to the abbreviated timeline regarding funding opportunities
for this affordable housing Project, we respectfully ask that requests for SB 18
consultation also be provided within 45 days, if practicable.

Your comments are important to the City of Rolling Hills. If the Gabrielino Tongva
Indians of California Tribal Council have any concerns regarding the proposed Project as
it relates to Native American issues or interests, or has any information regarding sacred
sites in the vicinity of the proposed Project that may help avoid impacts to those sites,
please send your response to:

John F. Signo, AICP
Planning Director
City of Rolling Hills
On December 14, 2021, Chambers Group, on behalf of the City of Rolling Hills , submitted Assembly Bill 52 (AB 52)
and Senate Bill 18 (SB 18) notification letters to eight tribal representatives from seven Native American tribal
governments that included the Gabrieleño Band of Mission Indians - Kizh Nation, the Gabrieleno/Tongva San Gabriel
Band of Mission Indians, the Gabrielino/Tongva Nation, the Gabrielino Tongva Indians of California Tribal Council, the
Gabrielino-Tongva Tribe, the Santa Rosa Band of Cahuilla Indians, and the Soboba Band of Luiseño Indian tribes for
the proposed General Plan Update to the Housing and Safety Elements (Project). Tribes had 30 days to respond to
AB 52 requests for consultation, or until January 13, 2022. Under GC 65352.3 tribes have 90 days to respond to SB 1 8
or until March 14 2022, however due to the abbreviated timeline for the Project, tribes were asked that consultation
be provided within 45 days , or by January 28, 2022. In addition, on December 15, 2021, an electronic version of the
letter was emailed to each of the eight designated tribal representatives , and a follow-up email that was sent on
December 29, 2021. Of the seven tribes and eight tribal representatives contacted, the City received responses from
two of the tribes, and those responses are detailed in the section below. As a final courtesy at an attempt for a
response, on January 19, 2022 a follow-up phone call was made to the remaining tribal governments that had not yet
responded, the Gabrieleno/Tongva San Gabriel Band of Mission Indians, the Santa Rosa Band of Cahuilla Indians, the
Soboba Band of Luiseño Indians, the Gabrielino/Tongva Nation, and the Gabrielino-Tongva Tribe. Messages were left
for these five remaining tribes and as of the date of this summary no responses have been received.
Responses and consultation requests were received from the following tribes within 30-days :
• Gabrieleño Band of Mission Indians - Kizh Nation (December 21, 2021): The tribe responded via email
within the 30-day timeframe under AB 52 and stated that we concur to be in agreement with the Housing
and Safety Elements Update. However, our Tribal government would like to request consultation for any
and all future projects when ground disturbance will be occurring within this location.
• Gabrielino Tongva Indians of California Tribal Council (December 31, 2021; January 6, 2022): The tribe
responded within the 30-day timeframe under AB 52 and requested formal government -to-government
consultation under AB 52 and SB 18.
o December 31, 2021, via email: Received email response requesting AB52 consultation for
development on the aforementioned project area. “The Tribe is deeply concerned with any
ground disturbances in your project area and this project will need a monitor.” This request
prompted a follow-up email from Richard Shultz with the clarification that there are no planned
projects or work activities that would warrant monitoring at this time, which was sent on January
3, 2022.
o January 6, 2022, via follow-up email: “At this time, as there are no specific developments planned,
we have no concerns. We are requesting to be notified on any future projects in the City of Rolling
Hills as aforementioned, it is a sensitive area for our tribe. We want to consult and perform
monitoring.”

A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
ROLLING HILLS ADOPTING THE SAFETY ELEMENT
UPDATE AND A NEGATIVE DECLARATION FOR THE
SAFETY ELEMENT
THE CITY COUNCIL DOES HEREBY FIND, RESOLVE, AND ORDER AS FOLLOWS:
Section 1. Recitals
A. On January 4, 1957, the City of Rolling Hills was established as a duly
organized municipal corporation of the State of California.
B. The City of Rolling Hills adopted its current General Plan on June 25, 1990.
The General Plan establishes goals, objectives, and strategies to achieve the
community’s vision for its future. A Safety Element was adopted as part of the General
Plan.
C. Section 65302(g) of the California Government Code requires that the
General Plan include a Safety Element for the protection of the community from any
unreasonable risks associated with the effects of seismically-induced surface rupture,
ground shaking, grand failure, tsunami, seiche, and dam failure; slope instability leading
to mudslides and landslides; subsidence and other geologic hazards; flooding, and
wildland and urban fire.
D. Senate Bill 99, effective January 1, 2020, requires the City to identify
residential developments in any hazard area identified in the safety element that does not
have at least two emergency evacuation routes.
E. Cities and counties in California are required to have a Safety Element that
is consistent with all other elements of the General Plan. The City’s 5th Cycle Housing
Element was certified by the California Department of Housing and Community
Development (HCD) on July 7, 2021, and the City is currently awaiting comments from
HCD on the 6th Cycle Housing Element. The Safety Element has been prepared to be
consistent with the Housing Element.
F. On January 18, 2022, the Planning Commission held a workshop to discuss
the Safety Element update.
G. On February 15, 2022, the Planning Commission held a public hearing in
accordance with law to consider making a written recommendation on the amendment of
the General Plan for purposes of the Safety Element update and on adoption of the
related Negative Declaration. At that meeting, the Planning Commission adopted
Resolution No. 2022-02 recommending that the City Council adopt the Safety Element
update.
727
Resolution No. 1291 -2- Safety Element
H. Pursuant to the provisions of the California Environmental Quality Act
(CEQA), Public Resources Code Sections 21000 et seq. and the State CEQA Guidelines
California Code of Regulations, Title 14, Sections 15000 et seq., the City prepared an
Initial Study (IS) and determined that there was no substantial evidence that adoption of
the update to the Safety Element may have a significant effect on the environment.
Accordingly, a draft Negative Declaration (ND) was prepared and notice of that fact was
given in the manner required by law. The City subsequently prepared an Errata to the
Draft IS/ND to clarify and insignificantly modify the Project. Specifically, the City removed
the Housing Element update from the Project. The changes do not affect the overall
conclusions of the environmental document; the analysis of the environmental impacts of
the Safety Element Update are fully covered in the previously circulated Draft IS/ND. The
changes that have been made to the Draft IS/ND in the errata do not constitute a
“substantial revision” to the IS/ND because the revisions (1) do not identify a new,
avoidable significant effect and mitigation measure or project revisions that must be
added in order to reduce the effect to insignificance; or (2) do not result in a change to
any mitigation measures that were previously disclosed (none were). (State CEQA
Guidelines, section 15073.5.) Because the project revisions do not result in any new
avoidable significant effects, recirculation is not required. (Id.)
I. On March 14, 2022, the City Council held a public hearing in accordance
with law to consider adoption of the Negative Declaration and Safety Element update.
The City Council continued the public hearing to March 28, 2022.
Section 2. Findings. Based upon the facts contained in this Resolution, those
contained in the staff report and other components of the legislative record, the City
Council finds that:
A. All environmental impacts of the amendment to the Safety Element are
either less than significant or no impact as outlined in the Negative Declaration and the
Initial Study. There is no substantial evidence in the record supporting a fair argument
that the amendment to the Safety Element may result in any significant environmental
impacts. The Negative Declaration contains a complete, objective, and accurate reporting
of the environmental impacts associated with the amendment to the Safety Element and
reflects the independent judgment and analysis of the City.
B. The Safety Element is consistent with the other elements of the General
Plan, including the Land Use Element, Circulation Element, and Open Space and
Conservation Element as set forth below:
Land Use Element Goal 3: Accommodate development that is sensitive to the
natural environment and accounts for environmental hazards.
The Safety Element is consistent with this goal in that it addresses the natural
environmental and accounts for environmental hazards.
Circulation Element Goal 2: Provide a circulation system that contributes to
residents’ quality of life and minimizes impacts on the environment.
728
Resolution No. 1291 -3- Safety Element
The Safety Element is consistent with this goal in that it plans for escape routes
that utilize the existing circulation system in the event of an emergency.
Open Space and Conservation Element Goal 1: Conserve and enhance the City’s
natural resources, facilitating development in a manner which reflects the
characteristics, sensitivities and constraints of these resources.
The Safety Element is consistent with this goal in that it considers safety factors
and hazard constraints in facilitating development.
C. The safety goals, objectives, and policies stated in the Safety Element are
appropriate for the City of Rolling Hills. The Safety Element will aid the City’s efforts for
the protection of the community and is in the public interest.
Section 3. The City Council of the City of Rolling Hills hereby adopts the Safety
Element, provided as Exhibit A, attached hereto and incorporated herein by reference,
and adopts the Negative Declaration, provided as Exhibit B, attached hereto and
incorporated herein by reference.
PASSED, APPROVED AND ADOPTED THIS 28th DAY OF MARCH 2022.
