DATE:January 18, 2022 BACKGROUND: With the Governor ’s approval of AB 361, public agencies have been granted the continuing ability to conduct virtual meetings during declared public health emergencies under specified circumstances until January 1, 2024. Based on the requirements of AB 361 (copy attached), in order for the City to hold virtual meetings, the Committee on Trees and Views needs to determine monthly that the following conditions exist: 1) There continues to be a health and safety risk due to COVID-19 as a proclaimed state of emergency with recommended measures to promote social distancing; and 2) Meeting in person during the proclaimed state of emergency would present imminent risks to the health and safety of attendees. The other requirements associated with continued virtual meetings are outlined in the text of AB 361. The recommended action is for the Committee on Trees and Views to find that the following conditions exist and that they necessitate remote Committee meetings for the coming month: 1) There continues to be a health and safety risk due to COVID-19 as a proclaimed state of emergency with recommended measures to promote social distancing; and 2) Meeting in person during the proclaimed state of emergency would present imminent risks to the health and safety of attendees. These findings will need to be made by the City Council each month that the City opts to continue with remote meetings. 4 DISCUSSION: None. FISCAL IMPACT: None. RECOMMENDATION: Approve as presented.

Date: 01/18/2022 TO:HONORABLE CHAIR AND MEMBERS OF THE PLANNING COMMISSION FROM:JOHN SIGNO, DIRECTOR OF PLANNING & COMMUNITY SERVICES THRU:ELAINE JENG P.E., CITY MANAGER SUBJECT:SAFETY ELEMENT UPDATE. DATE:January 18, 2022 BACKGROUND: 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 (Cal OES). The City obtained the professional services of Rincon Consultants, Inc. to prepare the Draft Safety Element. Once completed, the Draft Safety was sent to the California Board of Forestry and Fire Protection for review, but no recommendations or changes were made. DISCUSSION: 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. The Safety Element 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)). The Safety Element 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 10 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)). 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. Next Steps The Safety Element will be brought back to the Planning Commission with the Housing Element Update at a future meeting. Also to be considered is a negative declaration prepared pursuant to the California Environmental Quality Act (CEQA) Guidelines. The purpose of tonight's meeting is to introduce the Safety Element to the Planning Commission and solicit discussion. FISCAL IMPACT: The City obtained a grant from CalOES for $47,624 to update the Safety Element. Certification of the Element provides an indirect positive fiscal impact by reducing legal risks and qualifying the City for State planning grants. RECOMMENDATION: Discuss the update to the Safety Element and direct staff to prepare a final version for the Planning Commission and City Council's consideration.

Report 14 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, Table 1 Rolling Hills Climate Summary Climate Character Estimate Annual Average Observed Maximum Temperature from 1961 - 1990 (Fahrenheit) 71 Annual Average Observed Minimum Temperature from 1961 – 1990 (Fahrenheit) 50 Annual Average Observed Precipitation from 1961 – 1990 (inches) 19 Source: Cal-Adapt 2021 1 An older adult is any adult over the age of 65 years old. 15 City of Rolling Hills Rolling Hills General Plan 2 Table 2 Rolling Hills Demographic Characteristics Demographic Characteristics Estimate General Total Population 1,739 Population under 10 years 7 percent Population over 65 years 28 percent1 Race 77 percent White, 18 percent Asian, 5 percent Hispanic/Latino Disability (hearing, vision, cognitive, ambulatory) 12 percent Housing Total Households 6451 Average Household Size 2.76 Owner-occupied Households 96 percent Population over 65 years living alone 15 percent of those over 65 years Employment Unemployment Rate 6 percent Poverty Rate 2 percent Median Income $ 239,000 Insurance Coverage 97 percent Source: U.S. Census 2018 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, 16 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: Rolling Hills City Hall: 2 Portuguese Bend Road, Rolling Hills, CA Rolling Hills Community Association: 1 Portuguese Bend Road, Rolling Hills, CA Rancho Del Mar High School: 38 Crest Road West, Rolling Hills, CA Storm Hill Park: Agua Magna Canyon, Rolling Hills, CA Los Angeles County Sheriff’s Lomita Station: 26123 Narbonne Avenue, Lomita, CA Los Angeles County Fire Station No. 56: 12 Crest Road West, Rolling Hills, CA Los Angeles County Communications Tower: 5741 Crestridge Road, Rancho Palos Verdes, CA Southern California Edison Electrical Substation: Crestridge Road, Rancho Palos Verdes, CA Southern California Edison Electrical Substation: Tarragon Road, Rancho Palos Verdes, CA Southern California Edison Electrical Substation: 27873 Hawthorn Boulevard, Rancho Palos Verdes, CA California Water Service Reservoir: Palos Verdes Drive North/Palos Verdes Drive East (SW corner), Rolling Hills Estates, CA California Water Service Reservoir: 3960 East Crest Road, Rancho Palos Verdes, CA California Water Service Reservoir: Via Canada, Rancho Palos Verdes, CA California Water Service Reservoir: 1 Spur Lane, Rolling Hills, CA California Water Service Reservoir: 60 Eastfield Drive, Rolling Hills, CA Portuguese Bend Road Crest Road 17 City of Rolling Hills Rolling Hills General Plan 4 Rolling Hills Community Association 18 Introduction Safety Element 5 Figure 1 Critical Facilities Map 19 City of Rolling Hills Rolling Hills General Plan 6 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. 20 Hazards of Concern Safety Element 7 Figure 2 Landslide Hazard Zones 21 City of Rolling Hills Rolling Hills General Plan 8 Figure 3 Faults in the Vicinity of Rolling Hills 22 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. Table 3 Active Faults Located less than 50 Miles from 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 in the City boundaries Santa Monica 20 miles north-northwest *All faults listed are active. An active fault is one that has experienced surface movement in the past 11,000 years. 23 City of Rolling Hills Rolling Hills General Plan 10 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. 24 Hazards of Concern Safety Element 11 Figure 4 Rolling Hills Earthquake Shaking Potential 25 City of Rolling Hills Rolling Hills General Plan 12 Figure 5 Rolling Hills Liquefaction Hazard Areas 26 Hazards of Concern Safety Element 13 Figure 6 Dam Inundation Areas 27 City of Rolling Hills Rolling Hills General Plan 14 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 Los Angeles County Fire Station No. 56 28 Hazards of Concern Safety Element 15 Figure 7 Fire Hazard Zones 29 City of Rolling Hills Rolling Hills General Plan 16 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. Existing Fire Risk Reduction Strategies ▪ Rolling Hills Municipal Code (RHMC) Chapter 8.24 Abatement of Nuisances, Chapter 8.30: Fire Fuel Abatement, and Chapter 15.20 Fire Code ▪ Los Angeles County Fire Department Fuel Modification Plans ▪ Los Angeles County Fire Code Section 4908 ▪ Rolling Hills Community Wildfire Protection Plan vegetation management standard recommendations ▪ Rolling Hills Community Association fire fuel management strategies Portuguese Bend Road, south of Crest Road 30 Community Communication Safety Element 17 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 31 City of Rolling Hills Rolling Hills General Plan 18 Figure 8 Existing Evacuation Routes 32 Community Communication Safety Element 19 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. 33 City of Rolling Hills Rolling Hills General Plan 20 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. 34 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 35 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 36 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. 37 City of Rolling Hills Rolling Hills General Plan 24 Goals, Policies, and Implementation Hazard Mitigation Goal 1 Minimization of Loss of Life, Injury, and Property Damage Resulting from Geologic Hazards Policy 1.1 Ensure that existing structures throughout the City meet seismic safety standards and that new facilities are developed to updated standards.

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. 61 City of Rolling Hills Rolling Hills General Plan Safety Element 2 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. Table 1 Rolling Hills Climate Summary Climate Character Estimate Annual Average Observed Maximum Temperature from 1961 - 1990 (Fahrenheit) 71 Annual Average Observed Minimum Temperature from 1961 – 1990 (Fahrenheit) 50 Annual Average Observed Precipitation from 1961 – 1990 (inches) 19 Source: Cal-Adapt 2021 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. 1 An older adult is any adult over the age of 65 years old. 62 Introduction Existing Conditions Report 3 Table 2 Rolling Hills Demographic Characteristics Demographic Characteristics Estimate General Total Population 1,8601 Population under 10 years 7 percent Population over 65 years 28 percent1 Race 77 percent White, 18 percent Asian, 5 percent Hispanic/Latino Disability (hearing, vision, cognitive, ambulatory) 12 percent Housing Total Households 6451 Average Household Size 2.76 Owner-occupied Households 96 percent Population over 65 years living alone 15 percent of those over 65 years Employment Unemployment Rate 6 percent Poverty Rate 2 percent Median Income $ 239,000 Insurance Coverage 97 percent Source: U.S. Census 2018 1Information obtained from the Community Wildfire Protection Plan, which is includes more recent data than the U.S Census 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: Rolling Hills City Hall: 2 Portuguese Bend Road, Rolling Hills, CA Rolling Hills Community Association: 1 Portuguese Bend Road, Rolling Hills, CA Rancho Del Mar High School: 38 Crest Road West, Rolling Hills, CA Storm Hill Park: Agua Magna Canyon, Rolling Hills Los Angeles County Sheriff’s Lomita Station: 26123 Narbonne Avenue, Lomita, CA Los Angeles County Fire Station No. 56: 12 Crest Road West, Rolling Hills, CA Los Angeles County Communications Tower: 5741 Crestridge Road, Rancho Palos Verdes, CA Southern California Edison Electrical Substation: Crestridge Road, Rancho Palos Verdes, CA Southern California Edison Electrical Substation: Tarragon Road, Rancho Palos Verdes, CA 63 City of Rolling Hills Rolling Hills General Plan Safety Element 4 Southern California Edison Electrical Substation: 27873 Hawthorn Boulevard, Rancho Palos Verdes, CA California Water Service Reservoir: Palos Verdes Drive North/Palos Verdes Drive East (SW corner), Rolling Hills Estates, CA California Water Service Reservoir: 3960 East Crest Road, Rancho Palos Verdes, CA California Water Service Reservoir: Via Canada, Rancho Palos Verdes, CA California Water Service Reservoir: 1 Spur Lane, Rolling Hills, CA California Water Service Reservoir: 60 Eastfield Drive, Rolling Hills, CA Portuguese Bend Road Crest Road 64 Introduction Existing Conditions Report 5 Figure 1 Critical Facilities Map 65 City of Rolling Hills Rolling Hills General Plan Safety Element 6 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 66 Hazards of Concern Existing Conditions Report 7 Figure 2 Landslide Hazard Zones 67 City of Rolling Hills Rolling Hills General Plan Safety Element 8 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. 68 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. 69 City of Rolling Hills Rolling Hills General Plan Safety Element 10 Figure 3 Faults in the Vicinity of Rolling Hills 70 Hazards of Concern Existing Conditions Report 11 Figure 4 Rolling Hills Liquefaction Hazard Areas 71 City of Rolling Hills Rolling Hills General Plan Safety Element 12 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. Existing Fire Risk Reduction Strategies  Rolling Hills Municipal Code (RHMC) Chapter 8.30: Fire Fuel Abatement  VHRHSZ building requirements 72 Hazards of Concern Existing Conditions Report 13  Los Angeles County Fire Department property line and structure vegetation buffer requirements  Rolling Hills Community Wildfire Protection Plan vegetation management standard recommendations  Rolling Hills Community Association 73 City of Rolling Hills Rolling Hills General Plan Safety Element 14 Figure 5 Dam Inundation Areas 74 Hazards of Concern Existing Conditions Report 15 Figure 6 Fire Hazard Zones 75 City of Rolling Hills Rolling Hills General Plan Safety Element 16 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 76 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. 77 City of Rolling Hills Rolling Hills General Plan Safety Element 18 Figure 7 Existing Evacuation Routes 78 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) 79 City of Rolling Hills Rolling Hills General Plan Safety Element 20  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. 80 Climate Change Vulnerability 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 to rise strongly through 2050 and plateau around 2100) 81 City of Rolling Hills Rolling Hills General Plan Safety Element 22 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. 6 Chart shows the number of days in a year when daily maximum temperature is above the extreme hear threshold of 91.7 ̊F for Rolling Hills (Grid Cell 33.78125, -118.34375) under RCP 8.5 82 Climate Change Vulnerability Existing Conditions Report 23 Table 4 Changes in Annual Average Precipitation Scenario Annual Precipitation Minimum (inches) Average (inches) Maximum (inches) Historical Average (1950-2005) 6.7 19.2 37.0 Medium Emissions Scenario (2030-2099) 6.0 21.3 48.2 High Emissions Scenario (2030-2099) 4.8 22.2 57.0 Source: CEC 2020 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 83 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”) 8 Chart shows estimated intensity (Return Level) of Extreme Precipitation events which are exceeded on average once every 20 years (Return Period) for Rolling Hills (Grid Cell 33.78125, -118.34375) under RCP 8.5 emissions scenario. Extreme precipitation events are described as days during a water year (Oct-Sept) with 2-day rainfall totals above an extreme threshold of 1.02 inches. 84 Climate Change Vulnerability Existing Conditions Report 25 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. 85 City of Rolling Hills Rolling Hills General Plan Safety Element 26 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 86 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 87 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. 88 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, 89 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. 90 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.

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. 91 City of Rolling Hills Rolling Hills General Plan Safety Element 32 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 92 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. 93 City of Rolling Hills Rolling Hills General Plan Safety Element 34 Table 7 Vulnerability Assessment Results Community Sensitivity Storms/Extreme Weather Extreme Heat Wildfire Landslides Population Children V-3 V-2 V-2 Persons with Chronic Health Conditions V-2 V-4 V-4 V-2 Persons in Poverty V-2 V-3 V-4 V-2 Renters V-3 V-2 V-2 Older Adults V-2 V-4 V-4 V-2 Limited English Speaking V-2 V-2 Infrastructure Access Roads V-2 V-4 V-3 Bridle Trails V-2 V-3 V-2 Electrical Substations V-1 V-2 V-3 Electrical Utility Lines V-2 V-1 V-3 V-2 Natural Gas Transmission Pipelines V-2 V-2 Water Reservoirs and Systems V-1 V-2 V-3 V-3 Buildings and Facilities Residential Structures V-1 V-5 V-3 Community Facilities and Government Buildings V-1 V-4 V-1 Community Parks V-1 V-1 V-3 V-3 Schools V-1 V-3 V-1 Public Safety Facilities V-1 V-3 V-1 94 Climate Change Vulnerability Existing Conditions Report 35 Community Sensitivity Storms/Extreme Weather Extreme Heat Wildfire Landslides Services Public Safety Response V-2 V-3 V-1 Water Services V-2 V-2 V-3 V-2 Energy Delivery V-2 V-3 V-4 V-2 Notes: Drought was not included in this table because the city’s vulnerability to drought is primarily low.

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 96 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. 97 City of Rolling Hills Rolling Hills General Plan Safety Element 38 References California Department of Toxic Substances and Control (DTSC). 2020.

Date: 01/18/2022 TO:HONORABLE CHAIR AND MEMBERS OF THE PLANNING COMMISSION FROM:JOHN SIGNO, DIRECTOR OF PLANNING & COMMUNITY SERVICES THRU:ELAINE JENG P.E., CITY MANAGER SUBJECT: ZONING CASE NO. 21-13: REQUEST FOR APPROVAL OF A SITE PLAN REVIEW FOR A POOL, SPA, GRADING, AND OTHER IMPROVEMENTS FOR A PROPERTY LOCATED AT 4 STORM HILL LANE (GRZYWACZ) DATE:January 18, 2022 BACKGROUND: Zoning, Location, and Lot Description The property is zoned RAS-2 and has a net lot area of 298,606 square feet (6.86 acres). The lot is developed with a 5,453-square-foot single family residence and a 950-square-foot garage. There are five existing building pads on site with approximately 40 feet difference in elevation. The existing residence, garage and project area are located on the highest and largest pad (45,702 square feet) in the middle of the property; the secondary pad (16,311 square feet) is located behind the main pad and contains a tennis court and guesthouse; the third pad (18,228 square feet) is in the southern portion of the property and contains an arena and corral; the fourth pad (3,869 square feet) is located south of the main pad and includes a corral; the fifth pad (8,065 square feet) in the front of the property is developed with a corral and stable. The existing topography of the project site has a gradual slope and is an ideal location for a swimming pool and spa in that it is located outside of required setbacks. DISCUSSION: Project Description The applicant is proposing to construct a 920-square-foot swimming pool and spa, pool equipment, barbecue and kitchen area, patio extension, water feature, trellis, garden, garden walls, and landscaping. The project includes 4,761 square feet of new flatwork: 2,719 square feet of patio area and 2,042 square 110 for a pool deck. The proposed project will create 2,843 square feet of newly disturbed land and includes 496 cubic yards of grading, which wills be balanced on site. Excavation for the swimming pool is exempt from grading calculations, but is included as part of the project to level the grade. No import or export of dirt will occur. Site Plan Review The applicant is requesting a Site Plan Review (SPR) to exceed the 800 square feet allowed by-right for a swimming pool, and conduct 496 square feet of total grading. Swimming Pool The proposed swimming pool and spa is 920 square feet. A Site Plan Review is required because the pool and spa exceeds the 800 square feet allowed by right. Section 17.46.020.A.2.a of the Rolling Hills Municipal Code states: “A swimming pool and spa, which is less than eight hundred square feet in area (area of surface water), that do not require grading and when such construction would not cause exceedance of the requirements for structural and total net lot coverage and disturbed area of the lot. For the purpose of this section, the actual excavation for the swimming pool or spa is not considered grading. However, should there be a need to create a buildable pad for the purpose of locating the swimming pool or spa on the pad, and if such construction does not meet the exemption criteria pursuant to Section 15.04.120 of the Building and Construction Code, a site plan review shall be required.” The proposed pool and spa is more than 800 square feet, which is the maximum size allowed without a Site Plan Review. The proposed pool and spa will not encroach into any required yards and will be on relatively flat land. The proposed uses will be located behind the house in an area with views of the Los Angeles basin. There are other locations on site for the proposed uses, however, the other locations are on separate building pads and are much smaller. Locating the proposed uses on a higher elevation, behind the residence, eliminates the line of sight to the pool and does not block the view from adjacent residences. As such, the proposed location is viable and safe for a pool and spa due to the existing topography. Grading The applicant is requesting to use the excavated dirt from the proposed swimming pool area to flatten the surrounding area. Typically, dirt excavated for a swimming pool and spa is exempt from grading calculations, however, the applicant will be using the 113 cubic yards (CY) of dirt from the swimming pool/spa to flatten the surrounding area. As a result, no export of dirt will occur. The total grading for the project is 496 cubic yards (CY): 248 CY of cut and 248 CY of fill. A second area of grading near the front of the property will be done to create a garden area. A third area of grading occurs in the northern portion of the site to improve bio-infiltration of storm water. Balancing grading on site complies with the goals of the General Plan by eliminating the need to import or export dirt. The proposed grading will not impact site drainage. Section 17.46.050 - Required Site Plan Review findings. The Commission shall be required to make findings in acting to approve, conditionally approve, or deny a site plan review application. No project which requires Site Plan Review approval shall be approved by the Commission, or by the City Council on appeal, unless the following findings can be 111 made: 1. The project complies with and is consistent with the goals and policies of the General Plan and all requirements of the Zoning Ordinance; 2. The project substantially preserves the natural and undeveloped state of the lot by minimizing building coverage. Lot coverage requirements are regarded as maximums, and the actual amount of lot coverage permitted depends upon the existing buildable area of the lot; 3. The project is harmonious in scale and mass with the site, the natural terrain and surrounding residences; 4. The project preserves and integrates into the site design, to the greatest extent possible, existing topographic features of the site, including surrounding native vegetation, mature trees, drainage courses and land forms (such as hillsides and knolls); 5. Grading has been designed to follow natural contours of the site and to minimize the amount of grading required to create the building area; 6. Grading will not modify existing drainage channels nor redirect drainage flow, unless such flow is redirected into an existing drainage course; 7. The project preserves surrounding native vegetation and mature trees and supplements these elements with drought-tolerant landscaping which is compatible with and enhances the rural character of the community, and landscaping provides a buffer or transition area between private and public areas; 8. The project is sensitive and not detrimental to the convenient and safe movement of pedestrians and vehicles; and 9. The project conforms to the requirements of the California Environmental Quality Act. If all of the above findings cannot be made with regard to the proposed project, or cannot be made even with changes to the project through project conditions imposed by City staff and/or the Planning Commission, the Site Plan Review application shall be denied. Findings to support the proposed project are included in the resolution. Public Participation No calls or letters were received. Environmental Review The proposed project has been determined not to have a significant effect on the environment and is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) Guidelines pursuant to Section 15303 (New Construction or Conversion of Small Structures), which exempts accessory structures including garages, carports, patios, swimming pools, and fences. FISCAL IMPACT: None. RECOMMENDATION: Adopt Resolution No. 2022-01 approving a Site Plan Review for a swimming pool, spa, grading, and other improvements.

Property Owner, Claudia Grzywacz, (“Applicant”) for the real property located at 4 Storm Hill Lane, Rolling Hills, CA is requesting a Site Plan Review for the construction of a new 920-square-foot swimming pool and spa; and 496 cubic yards of grading located on the main building pad (the “Project”). Also included in the Project, but not subject to discretionary review, is a request for a pool deck, pool equipment, barbecue and kitchen area, patio extension, water feature, trellis, garden, garden walls with a maximum height of three feet, and landscaping. The Project will be located adjacent to the residence and outside of all required setbacks. Section 2. The Planning Commission conducted duly noticed public hearings to consider the application at an onsite meeting on January 18, 2022, at 7:34 AM and at their regular meeting on January 18, 2022, at 6:30 PM. Neighbors within a 1,000-foot radius were notified of the public hearings and a notice was published in the Daily Breeze on January 7, 2022. The Applicant and her agent were notified of the public hearings in writing by first class mail and the Applicant and her agent were in attendance at the hearings. Section 3. The property is zoned RAS-2 with a net lot area of 298,606 square feet (6.86 acres), which exceeds the requirements of the RAS-2 zone that requires a minimum net lot area of 87,120 square feet. The lot is developed with a 5,453-square- foot single family residence and a 950-square-foot garage. There are five existing building pads on site with approximately 40 feet difference in elevation. The existing residence, garage, and Project area are located on the highest and largest pad (45,702 square feet) in the middle of the property; the secondary pad (16,311 square feet) is located behind the main pad and contains a tennis court and guesthouse; the third pad (18,228 square feet) is in the southern portion of the property and contains an arena and corral; the fourth pad (3,869 square feet) is located south of the main pad and includes a corral; the fifth pad (8,065 square feet) in the front of the property is developed with a corral and stable. 129 2 Resolution 2022-01 4 Storm Hill Lane Section 4. The Project is exempt from the California Environmental Quality Act (CEQA) Guidelines pursuant to Section 15303, Class 3 (New Construction or Conversion of Small Structures), which exempts the construction and location of a limited numbers of new, small facilities or structures, including accessory structures, such as swimming pools, because it involves the construction of a 920-square-foot swimming pool. The Project is also exempt from CEQA Guidelines pursuant to Section 15301, Class 1 (Existing Facilities), which exempts the minor alteration of topographical features involving negligible or no expansion of use beyond that existing, because the Project involves minimal grading totaling 496 cubic yards (248 cubic yards cut and 248 cubic yards of fill) that will be balanced on site and will not affect the natural topography of the site. Section 5. Section 17.16.020.A of the Rolling Hills Municipal Code requires Site Plan Review approval for a swimming pool/spa that is eight hundred square feet or greater, and for projects that require grading. The Applicant proposes the construction of a 920-square-foot swimming pool/spa and 496 cubic yards of grading. The Project also includes a pool deck, pool equipment, barbecue and kitchen area, patio extension, water feature, trellis, garden, garden walls with a maximum height of three feet, and landscaping, which are not subject to discretionary approval. With respect to the aforementioned request for a Discretionary Approval for a Site Plan Review, the Planning Commission finds as follows: A. The proposed Project complies with and is consistent with the goals and policies of the general plan and all requirements of the zoning ordinance. The proposed pool/spa and other improvements will be constructed on the existing main building pad in the northern portion of the subject property. While disturbance is generally limited to forty percent of the net lot area, the disturbed area may be a maximum of fifty percent of the net lot area in order to encourage a gradual transition in grade and undulated and natural-appearing terrain between building pads and the surrounding slope, provided that no more than fifty percent of the slopes resulting from grading are greater (steeper) than 3:1, or three units horizontal (run to one unit vertical (rise). The Project creates areas of 2:1 slope adjacent to the new garden area and north of the new spa, but these areas are less than fifty percent of the slopes resulting from grading. The Project adds 1% of newly disturbed area to the 41% already disturbed, which will not exceed the maximum permitted amount of 50% since no more than 50% of the slopes resulting from the grading are greater (steeper) than 3:1, and development will be located outside of required setbacks. The granting of a Site Plan Review for the new pool/spa is consistent with the purposes and objectives of the General Plan because the proposed Project is consistent with similar amenities in the community, meets all the applicable code development standards and is located in an area on the property that is adequately sized to accommodate the proposed project. Additionally, the proposed 496 cubic yards of grading will be balanced on site and no export of dirt is required. 130 3 Resolution 2022-01 4 Storm Hill Lane B. The Project substantially preserves the natural and undeveloped state of the lot by minimizing building coverage. The Project substantially preserves the natural and undeveloped state of the lot by balancing grading on site. The topography and the configuration of the irregular-shaped lot have been considered, and it was determined that the proposed Project will not adversely affect or be materially detrimental to adjacent uses, buildings, or structures. The proposed pool/spa will be located in the northern portion of the property on an existing building pad currently used for backyard activities. The pool equipment will be located behind the garage and be screened by a wooden fence. The Project will not impact the view or privacy of surrounding neighbors. The Project requires 496 cubic yards of grading, which will be balanced on site. C. The Project is harmonious in scale and mass with the site, the natural terrain and surrounding residences. The Project is harmonious in scale and mass with the site and preserves the natural terrain. It poses no adverse impacts to the surrounding residences. The proposed Project will be orderly, attractive, and will not affect the rural character of the community. The proposed pool/spa and other improvements are located in the northern portion of the property, and the proposed pool equipment area will be located behind the garage and screened by a wooden fence. No impacts to views from the surrounding residences will occur. D. The Project preserves and integrates into the site design, to the greatest extent possible, existing topographic features of the site, including surrounding native vegetation, mature trees, drainage courses and land forms (such as hillsides and knolls). The proposed pool will be built on an existing pad. The net lot is 6.86 acres and is sufficient to accommodate the proposed use. There will be no significant changes to the site design, as the residential uses will remain and the pool/spa and deck will be constructed in an already disturbed area. The existing topography or topographic features will not be affected and the trees, vegetation, plants, flowers, and natural landscaping will remain. New landscaping will be planted to match or complement existing landscape features. There will be no change to the drainage course. E. Grading has been designed to follow natural contours of the site and to minimize the amount of grading required to create the building area. Grading will not affect the natural topography of the site. The proposed Project will be built on an existing pad. The Project proposes minimal grading totaling 496 cubic yards. Overall grading will include 248 cubic yards cut and 248 cubic yards of fill, which will be balanced on site. Excavated dirt from the pool will be used to flatten adjacent areas. No dirt will be exported. 131 4 Resolution 2022-01 4 Storm Hill Lane F. Grading will not modify existing drainage channels nor redirect drainage flow. No drainage channels will be affected by the proposed grading. The proposed grading is already located in a disturbed area currently used as a backyard for the house. G. The Project preserves surrounding native vegetation and mature trees and supplements these elements with drought-tolerant landscaping which is compatible with and enhances the rural character of the community and landscaping provides a buffer or transition area between private and public areas. Disturbed areas will be re-landscaped to match or complement existing landscape features. H. The Project is sensitive and not detrimental to the convenient and safe movement of pedestrians and vehicles. The proposed pool/spa and deck are located in the northern portion of the property and in the center of the back yard on the main building pad. The pool equipment will be located behind the existing garage. The Project is not located near any roads, driveways, garages, or any vehicular areas. There are safe walkways surrounding the proposed location of the pool/spa and deck. The existing vehicular road accesses are not near the Project site. I. The Project conforms to the requirements of the California Environmental Quality Act. The Project is exempt from the CEQA Guidelines pursuant to Section 15303, Class 3 (New Construction or Conversion of Small Structures), which exempts the construction and location of a limited numbers of new, small facilities or structures, including accessory structures, such as swimming pools, because it involves the construction of a 920 square foot swimming pool. The Project is also exempt from CEQA Guidelines pursuant to Section 15301, Class 1 (Existing Facilities), which exempts the minor alteration of topographical features involving negligible or no expansion of use beyond that existing, because the Project involves minimal grading totaling 496 cubic yards (248 cubic yards cut and 248 cubic yards of fill) that will be balanced on site and will not affect the natural topography of the site Section 6. Based upon the foregoing findings, the Planning Commission hereby approves the Site Plan Review in Zoning Case No. 21-13 for the construction of a new 920-square-foot swimming pool and spa, and grading subject to the following conditions: A. The Site Plan Review Permit approval shall expire within two years from the effective date of approval if construction pursuant to this approval has not commenced within that time period, as required by Section 17.46.080 of the Rolling Hills Municipal Code, or the approval granted is otherwise extended pursuant to the requirements of those sections. 132 5 Resolution 2022-01 4 Storm Hill Lane B.
