SUBJECT:ZONING CASE 21-29: REQUEST FOR APPROVAL OF A CONDITIONAL
USE PERMIT AND A VARIANCE TO ALLOW A NEW 934-SQUARE-
FOOT STABLE AND EXISTING 3,500-SQUARE-FOOT CORRAL TO BE
LOCATED WITHIN THE REAR AND SIDE YARD SETBACKS AND
EXCEED THE LOT COVERAGE FOR A PROPERTY LOCATED AT 29
CREST ROAD WEST (LOT 174-C-2-MS), ROLLING HILLS, CA
(PERRIN).
DATE:March 15, 2022
BACKGROUND:
Zoning, Location, and Lot Description
The property located at 29 Crest Road West is zoned RAS-2 and has a net lot area of 59,850
square feet (1.37 acres). The lot is developed with a 5,413-square-foot single family residence
and a 1,125-square-foot garage. The project site slopes downward from the residence to the
rear of the lot. There is a 14-foot grade difference from the residence and pool area to the
proposed stable and corral. The existing residence, garage and pool are located on the first
pad (34,000 square feet) which is the upper portion of the lot located closest to Crest Road
West; the second pad (13,600 square feet) contains a tennis court; the third pad (9,200
square feet) is located in the rear of the property and is currently developed with two
freestanding 12-foot-high wooden chicken coops and a 3,500-square-foot white corral.
DISCUSSION:
Applicant Request
The applicant is proposing to build a new 934-square-foot stable and maintain the existing
3,500-square-foot corral fence in the rear portion of the lot. Two new planter walls with a
maximum height of four feet are proposed to be installed between the existing tennis court and
the stable; this involves 8 cubic yards (cy) of grading (4 cy of cut and 4 cy of fill). In addition,
8
the two existing chicken coops will be demolished. The stable will include 934 square feet of
new flatwork. The new stable would allow the applicant to keep two horses on-site and would
allow direct access to John’s Canyon Trail and a bridle trail which are located adjacent to the
rear and side yard of the project site. No additional landscaping is proposed adjacent to the
existing corral.
In the 1960’s, the project site was vacant and was part of a larger subdivision that was
developed with a community riding ring for use by residents of the City. In 1973, the property
owner sought approval of a new home, tennis court, and a stable to be located in the front
yard. The request for the stable was rejected by the Planning Commission due to concerns
about lot coverage and the proposed location of the stable in the front; however, the property
owner agreed to grant an easement to maintain the rear portion of the lot as a horseback
riding ring for the community (See attached Planning Commission Minutes dated May 1,
1973). The current property owner/applicant has obtained a quit claim for the community riding
ring easement.
Conditional Use Permit (CUP)
As per Rolling Hills Municipal Code Section 17.80.050, a Conditional Use Permit is required
for a stable greater than 200 square feet and a corral that is greater than 550 square feet in
size. The applicant is requesting approval of a Conditional Use Permit for the proposed 934-
square-foot stable and existing 3,500-square-foot corral. The corral was constructed in the
1970s and was used as a community riding ring. The easement for the riding ring has been
removed; however, the corral is still intact. The new stable and corral will be situated
approximately 8-feet below the existing tennis court on gradually sloping area in the rear
portion of the property.
Variances for reduced setbacks and exceedance of lot coverage
The applicant is requesting approval of a variance for a new 934-square-foot stable and an
existing 3,500-square-foot corral that will encroach into the required side and rear yard
setbacks and exceed the maximum 35% lot coverage.
Variance request to allow a new stable to encroach into the required setbacks:
The RAS-2 Zoning district requires a stable to maintain a minimum 35-foot side yard setback
and a 50-foot rear yard setback from other structures. The proposed stable would be setback
32 feet from the east side yard and 30 feet from the west side yard; this would result in an
encroachment of 3 feet and a 5 feet, respectively. The stable would be setback 85 feet from
the eastern rear property line and 80 feet from the western rear property line; this exceeds the
minimum required 50-foot rear yard setback. The setbacks for the proposed stable are shown
in the Table 1 below.

Variance request to allow an existing corral to encroach into the required setbacks:
The RAS-2 Zoning district requires a corral to maintain a minimum 25-foot side yard setback
and a 25-foot rear yard setback. The existing corral was a constructed in the 1970s and was
used as a community riding ring; the easement for the riding ring has been removed, however
the corral is still intact. The corral has an existing setback of 6 feet from the east side yard and
12.5 feet from the west side yard; this results in an encroachment of 19 feet and 12.5 feet into
the required 25-foot side yard setbacks, respectively. The corral has an existing setback of 20
feet from the east rear yard and 10 feet from the west rear yard; this would result in an
encroachment of 5 feet and 15 feet into the 25-foot required rear yard setback, respectively.
The setbacks for the proposed stable are shown in Table 2 below.

Yes. The stable exceeds the
required 35’ setback from
neighboring structures.
Variance request to allow a new stable to exceed the maximum lot coverage.
The minimum lot size for property within the RAS-2 zone is 87,120 square feet. The project
10
site is 59,850 square feet (1.37 acres) in area which is 27,270 square feet smaller than the
minimum lot size for the RAS-2 zoning district. However, since the property was legally
subdivided the lot size is considered legal nonconforming. The lot consists of an unusual lot
configuration; it is wider in the front and narrows in width as it slopes downward toward the
rear of the site.
The proposed structural coverage on the lot is 17,108 square feet (29%) which exceeds the
lot coverage limitations (20% maximum permitted); the proposed 934-square-foot stable
further increases the existing 38% lot coverage by 2%. The proposed total coverage for
structures and flatwork will be 23,933 square feet or 40% which also exceeds the lot coverage
limitation of 35% maximum. Therefore, a Variance is required to allow the increase in
structural and lot coverage for the proposed stable.
Upon subdivision, this property was burdened with an easement in favor of the adjacent
property for a community riding ring. The current property owners were successful in removing
the easement; however, the existence of the easement impacted the nature of the
development of the project. Additionally, the property occupies the northeast corner of the
intersection John’s Canyon and Crest Road West. The property was originally developed with
a driveway off John’s Canyon. To facilitate mail delivery to the corresponding Crest Road East
street address, the driveway was relocated from John’s Canyon to provide access from Crest
Road East. As a result, a large circular motor court was constructed on Crest Road East
which accounts for the majority of the excess lot coverage.
MUNICIPAL CODE COMPLIANCE
Area of Disturbance for the Stable and Corral
The project site has been previously disturbed due to development of two freestanding 12-foot
tall wood chicken coops and the existing 3,500-square-foot corral which was formerly used as
a riding ring. The two chicken coops would be demolished and replaced by a new 934-square-
foot stable and the existing corral will remain intact. The new 934-square-foot stable will
occupy 2% of the lot; the area of disturbance will increase from 38% to 40%.
Access to Stable
The stable and corral will be accessed via a 6-foot-wide service driveway that on the eastern
property line consisting of decomposed granite.
Height of stable and corral fencing
The ridgeline of the new stable would be 14’-6” in height. The existing 3,500-square-foot corral
consists of a white three-rail fence. The new stable and the existing corral would be situated
approximately 8 feet below the existing tennis court on a gradually sloping area in the rear
portion of the property.
Lot Coverage
The proposed structural coverage on the lot will be 17,108 square feet, or 29% of the lot,
which exceeds the lot coverage limitations of 20% maximum. The proposed 934-square-foot
stable increases the lot coverage by 2%. The proposed total coverage including structures and
flatwork will be 23,933 square feet or 40% of the lot area which also exceeds the lot coverage
11
limitation of 35% maximum. Therefore, a Variance is required to allow the minor increase in lot
coverage.
Lot Disturbance
The disturbed area may be up to 60% of the net lot area provided that at no point the slopes
resulting from grading are greater (steeper) than 3:1, or three units horizontal (run) to one unit
vertical (rise). The proposed project does not include grading as the corral area has been
disturbed and has a slope of less than 3:1. Construction of the stable will not increase lot
disturbance.
Environmental Review
The proposed project has been determined to not have a significant effect on the environment
and is categorically exempt from the provisions of CEQA pursuant to Section 15303 (New
Construction or Conversion of Small Structures) of the CEQA Guidelines, which exempts
accessory structures including stables, corrals, and fences.
Public Participation
A resident inquired about the number of horses that will be permitted to occupy the stable;
however, the Municipal Code does not regulate the number of horses. According to the
applicant, there will be no more than two horses in the stable. Secondly, there was a comment
about adding more landscaping along the rear property line where the corral is located; there
is some vegetation along the rear property line but no additional landscaping is proposed as
part of the project.
CRITERIA FOR APPROVAL OF CONDITIONAL USE PERMIT
17.42.050 Basis for approval or denial of Conditional Use Permit.

AT 29 CREST ROAD WEST (LOT 174-C-2-MS), ROLLING HILLS,
CA (PERRIN)
THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DOES
HEREBY FIND, RESOLVE AND ORDER AS FOLLOWS:
Section 1. Property Owners, Patrick and Donna Perrin, ("Applicant") for the
real property located at 29 Crest Road West, Rolling Hills, CA are requesting a
Conditional Use Permit and Variance for a new 934-square-foot stable and existing
3,500-square-foot corral to encroach into the required side and rear yards (the
"Project"). The project includes two planter walls between the tennis court and
corral that will have a maximum height of four feet and requires approximately eight
cubic yards of grading. The Project will be located adjacent to trails on the east and
north of the stable and corral.
Section 2. The Planning Commission conducted duly noticed public
hearings to consider the application at an onsite meeting on March 15, 2022, at
7:30 AM and at its regular meeting on March 15, 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 March 5, 2022. The Owners and their agent were
notified of the public hearings in writing by first class mail and the Owners and their
agent were in attendance at the hearings.
Section 3. The property is zoned RAS-2 with a net lot area of 59,850 square
feet (1.37 acres), which is smaller than 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
5,413-square-foot single family residence and a 1,125-square-foot garage. There are
three existing building pads on site with approximately 14 feet difference in
elevation. The existing residence, garage and pool are located on the highest and
largest pad (37,000 square feet) located near Crest Road West; the secondary pad
(13,060 square feet) is in the middle of the property and is developed with a tennis
court; the third pad (9,200 square feet) is in the rear of the property and includes
two 12-foot tall chicken coops and a 3,500-square-foot corral that was constructed
as part of a former community horseback riding ring.

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 number of new, small facilities or structures, including accessory
structures, such as a stable and corral, because it involves the construction of a
934-square-foot stable and maintenance of an existing 3,500-square-foot corral.
The Project is also exempt from the 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 site involves approximately eight cubic yards of grading for new planter
walls.
Section 5. Section 17.16.020.A of the Rolling Hills Municipal Code requires
a Variance for projects that encroach into the required setbacks and exceed the
maximum allowable lot coverage.
Section 6. Section 17.18.060 of the Zoning Ordinance contains conditions
for a stable and corral, subject to approval of a conditional use permit. The
proposed stable and corral comply with the provisions of this section. With respect
to this request for a Conditional Use Permit, the Planning Commission finds as
follows:
A. That the proposed conditional use is consistent with the General
Plan; The granting of a Conditional Use Permit for the stable and corral would
be consistent with the purposes and objectives of the Zoning Ordinance and
General Plan.
B. That the nature, condition and development of adjacent uses,
buildings and structures have been considered, and that the use will not
adversely affect or be materially detrimental to these adjacent uses, building or
structures; The nature, condition, and development of adjacent structures
have been considered, and the project will not adversely affect or be materially
detrimental to these adjacent uses, buildings, or structures because the
proposed uses (stable and corral) are located of sufficient distance from
nearby residences so as to not impact the view or privacy of surrounding
neighbors.
C. That the site for the proposed conditional use is of adequate size
and shape to accommodate the use and buildings proposed; The property is
adequately sized to accommodate such use, and on an existing level building pad.
The proposed use is appropriately located in that it will be sufficiently separated from
nearby structures.
31
3
D. That the proposed conditional use complies with all applicable
development standards of the zone district; The proposed uses (stable and
corral) meet the standards for the minimum size and height standards set forth in
the Rolling Hill Municipal Code; however, variances are required for
encroachments into the required side yard and rear yard setbacks and for
exceedance of the maximum lot coverage.
E. That the proposed use is consistent with the portions of the Los
Angeles County Hazardous Waste Management Plan relating to siting and siting
criteria for hazardous waste facilities; The proposed conditional use is consistent
with the portions of the Los Angeles County Hazardous Waste Management Plan
relating to siting criteria for hazardous waste facilities because the project site is not
listed on the current State of California Hazardous Waste and Substances Sites List.
F. That the proposed conditional use observes the spirit and intent
of this title. The project is harmonious in scale and mass with the site, the
natural terrain, and surrounding residences because the proposed use
complies with the low-profile residential development pattern of the community
and will not give the property an over-built look. Sufficient areas of the lot will
remain open and unobstructed. The lot is sufficiently large to accommodate
the proposed use.
Section 7. Sections 17.38.010 through 17.38.050 of the Rolling Hills
Municipal Code permit approval of a Variance when exceptional or extraordinary
circumstances applicable to the property, and not applicable to other similar
properties in the same zone, prevent the owner from making use of a parcel of
property to the same extent enjoyed by similar properties in the same vicinity. The
Applicant requests Variances from Sections 17.18.090.3 and17.16.070.A to allow
a stable and corral to encroach into the side and rear yard setbacks, allow the
structural coverage to exceed the maximum 20%, and allow the lot coverage to
exceed the maximum 35%.
With respect to this request for Variances, the Planning Commission finds
as follows:
A. That there are exceptional or extraordinary circumstances or conditions
applicable to the property that do not apply generally to other properties in
the same vicinity and zone.
There are several extraordinary circumstances applicable to this property. The
minimum lot size for property within the RAS-2 zone is 87,120 square feet. The
project site is 59,850 square feet (1.37 acres) which is 27,270 square feet smaller
than the minimum lot size; this is considered legal nonconforming. The lot consists
of an unusual lot configuration; it is wider in the front and narrows in width as it
slopes toward the rear of the site. Upon subdivision, this property was burdened
with an easement in favor of the adjacent property for a community riding ring. No
other property in the vicinity was burdened with such an easement. The property
32
4
owners were successful in removing the easement; however, the existence of the
easement impacted the nature of the development of the property. Additionally, the
property occupies the northeast corner of the intersection of Johns Canyon Road
and Crest Road West. The property has a Crest Road West address but the site
was originally developed with a driveway on Johns Canyon Road. To facilitate mail
delivery to the corresponding street address, the driveway was relocated to provide
access from Crest Road and a large circular motor court was constructed which
accounts for the majority of the excess lot coverage. These circumstances do not
apply to other properties in the vicinity.
B. That such variance is necessary for the preservation and enjoyment of
substantial property rights possessed by other properties in the same vicinity
and zone but which is denied the property in question.
Granting the requested variance for the stable and corral to encroach into the
side and rear yard setbacks and to exceed the maximum lot coverage will
facilitate construction of a stable on the property. The existing structural coverage
is 27% and the existing lot coverage is 38%. The proposed 934-square-foot stable
would increase structural and lot coverage by 2% bringing the total to 29% and
40%, respectively. Construction of the stable will result in a minor increase in lot
coverage and having a stable and corral on-site is a property right enjoyed by
other properties in the vicinity.
C. That the granting of such variance will not be materially detrimental to the
public welfare or injurious to properties or improvements in the vicinity.
Granting a variance to construct the proposed stable and corral will not be
detrimental to the public welfare and will not be injurious to properties in the vicinity;
horse keeping facilities are allowed and encouraged in the Rolling Hills equestrian
community. Further, the project will be consistent with other equestrian
development in the area.
D. That in granting the variance, the spirit and intent of this title will be observed.
The stable and corral are harmonious in scale and mass with the site, the
natural terrain, and surrounding residences because the proposed use
complies with the low-profile residential development pattern of the
community and will not give the property an over-built look. The lot is
sufficient to accommodate the proposed use.
E. That the variance does not grant special privilege to the applicant.
A stable and corral are common amenities enjoyed by many properties
throughout the City. The proposed project, together with the variances, will be
compatible with the objectives, policies, general land uses, and programs
specified in the General Plan.
F. That the variance is consistent with the portions of the County of Los Angeles
Hazardous Waste Management Plan relating to siting and siting criteria for
hazardous waste facilities.
33
5
Granting a variance to construct the proposed stable and maintain an existing
corral will be consistent with the applicable portions of the Los Angeles County
Hazardous Waste Management Plan related to siting criteria for hazardous waste
facilities.
G. That the variance request is consistent with the General Plan of the City of
Rolling Hills.
Granting the variance to exceed the maximum lot coverage to construct a two-stall
stable will be consistent with the General Plan of the City of Rolling Hills, which
allows and encourages horse keeping equestrian facilities in this equestrian
community.
Section 8. Based upon the foregoing findings, the Planning Commission
hereby approves Zoning Case No. 21-29, a request for a Conditional Use Permit for a
934-square-foot stable and a 3,500-square-foot corral and a Variance to 1) allow
the stable to encroach three feet and five feet into the east and west 35-foot side yard
setbacks, respectively, while maintaining a minimum setback of 80 feet from the nearest
adjacent residences and 2) allow the corral to encroach six feet and 12.6 feet into the
east and west side yard setbacks, respectively, and encroach five feet and 15 feet into
east and west rear yard setback, respectively, and 3) allow the 934-square-foot stable
to further increase the structural coverage from 27% to 29% and total lot coverage from
38% to 40%.
A. The Conditional Use Permit and Variance 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
17.42.070 and 17.38.070 of the Rolling Hills Municipal Code, or the approval
granted is otherwise extended pursuant to the requirements of those sections.
B. If any condition of this resolution is violated, the entitlement granted
by this resolution shall be suspended and the privileges granted hereunder shall
lapse and upon receipt of written notice from the City, all construction work being
performed on the subject property shall immediately cease, other than work
determined by the City Manager or his/her designee required to cure the
violation. The suspension and stop work order will be lifted once the Applicant
cures the violation to the satisfaction of the City Manager or his/her designee. In
the event that the Applicant disputes the City Manager or his/her designee's
determination that a violation exists or disputes how the violation must be cured,
the Applicant may request a hearing before the City Council. The hearing shall
be scheduled at the next regular meeting of the City Council for which the agenda
has not yet been posted, the Applicant shall be provided written notice of the
hearing. The stop work order shall remain in effect during the pendency of the
hearing. The City Council shall make a determination as to whether a violation of
this Resolution has occurred. If the Council determines that a violation has not
occurred or has been cured by the time of the hearing, the Council will lift the
suspension and the stop work order. If the Council determines that a violation
34
6
has occurred and has not yet been cured, the Council shall provide the Applicant
with a deadline to cure the violation; no construction work shall be performed on
the property until and unless the violation is cured by the deadline, other than
work designated by the Council to accomplish the cure. If the violation is not
cured by the deadline, the Council may either extend the deadline at the
Applicant's request or schedule a hearing for the revocation of the entitlements
granted by this Resolution pursuant to Chapter 17.58 of the Rolling Hills
Municipal Code (RHMC).

AT 23 CREST ROAD EAST (LOT 132A-MS), ROLLING HILLS, CA 90274
(WILLIAMS).
DATE:March 15, 2022
BACKGROUND:
Zoning, Location, and Lot Description
The property is zoned RAS-2 and excluding the roadway easement the lot is 262,368 square
feet (6.02 acres) in size. The lot is vacant. The existing topography of the project site slopes
down approximately 115 feet from Crest Road East to the lowest portion of the lot.
On January 2017, the City Council adopted a resolution approving an entitlement (ZC 902) for
construction of an 11,500 square foot new single family residence with an 11,500 square foot
basement and appurtenances (See City Council Resolution 1202). On December 12, 2018,
the Planning Commission granted a 2-year time extension for the entitlement ZC 902 to
January 23, 2021. Due to COVID-19 several entitlements were placed on hold and Assembly
Bill 1561 created an automatic extension of time and for ZC 902 which extend the expiration
date to July 22, 2022. However, should the Planning Commission and City Council approve
the proposed Project (ZC 21-11), the previous entitlement (ZC 902) will be superseded and no
38
longer valid.
DISCUSSION:
Applicant Request
The project consists of grading and construction of a new residence, driveway, guest house,
swimming pool, stable and covered turnout and appurtenant structures, on a vacant lot. Four
building pads are proposed. The first pad (Pad 1) is located in the upper northwest portion of
the lot (Pad 1) is proposed to be developed with a Zen garden (125 square feet), landscaped
yard area, concrete stairs, and the primary driveway. The second pad (Pad 2) is located in the
upper northeast portion of the lot and is proposed to be developed with a stable (2,260 square
feet), loft (196 square feet), covered turnout (1,225 square feet), corral (8,050 square feet)
pasture (8,050 square feet) and a secondary service driveway (3,908 square foot) for access
to the stable. The third pad (Pad 3) is located in the center of the lot and is proposed to be
developed with a residence (8,460 square feet) with a full basement (8,460 square feet and
15’ in depth), light wells for the basement emergency egress (124 square feet), two attached
garages (1,150 square feet) the primary driveway and motor court (8,050 square feet), guest
house (800 square feet), attached covered porches (570 square feet), pool and spa (1,130
square feet) with a trough (130 square feet), pool equipment (48 square feet), pond (200
square feet), service yard (120 square feet), an outdoor kitchen (85 square feet), partition
wall (45 square feet), fire pit (30 square feet), and two sheds (120 square feet). The fourth
pad (Pad 4) is located in the lower southern portion of the lot and is proposed to be developed
with a concrete stairway and a raised deck (520 square feet). The project also includes
landscaping, new flatwork including a main driveway and motor court, a secondary driveway to
access the stable, new patio areas, a pool deck, and concrete stairs.
Site Plan Review
As per Rolling Hills Municipal Code Section 17.46.020.A.2.a, a Site Plan Review (SPR) is
required for a swimming pool that exceeds 800 square feet. The proposed 1,130-square-foot
pool and spa exceeds the 800-square-foot limit by 330 square feet. The pool and spa will not
encroach into any required yards. The pool and spa will be located behind the house in an
area with views of the Pacific Ocean and Santa Catalina Island. Locating these proposed
uses on the same pad elevation, behind the residence, eliminates the line of sight to the pool.
Grading
The total grading for the project is proposed to be 64,760 cubic yards (CY): 32,110 CY of cut
and 32,110 CY of fill. Grading will be balanced on site.
The upper northwest portion of the lot (Pad 1) includes 1,515 CY of grading for a Zen garden,
a level front yard area, concrete stairs and the main driveway to the residence; the depth of
the cut will not exceed 6.5’ and the fill will be 2’. The upper northeast portion of the lot (Pad 2)
includes 10,260 CY of grading for a stable and covered turnout, pasture area and a secondary
driveway that would connect to the main driveway as well as provide access to the stable from
Crest Road East; the depth of the cut will range from 7.75’ to 12.75’ and fill will not exceed
6.75’.
The middle portion of the lot (Pad 3) includes 52,425 CY for the new residence, basement, two
39
attached garages, covered porches, outdoor kitchen, fire pit, pond, sheds, guest house and
pool and spa; the depth of the cut will range from 3’ to 22’ and the fill will range from 5’ to 10'.
The lower southern portion of the lot (Pad 4) includes 20 CY of grading for a concrete stairway
and a 520-square-foot raised deck; the fill will be 1.5’ with no cut.
The applicant is proposing to use the excavated dirt to flatten surrounding areas. No dirt will be
exported. Maximizing the amount of fill on the subject property complies with the goals of the
General Plan to balance grading on site. A breakdown of the grading is shown in the table
below.

Conditional Use Permit
As per Rolling Hills Municipal Code section 17.80.050 a conditional use permit is required for a
stable greater than 200 square feet and a corral that is greater than 550 square feet in size.
The proposed 1,130 square foot stable and covered turnout exceed the 200-square-foot limit
by 930 square feet. The proposed stable and turnout will not encroach into any required
setbacks.
As per Rolling Hills Municipal Code section 17.16.210 a conditional use permit is also required
to construct a guest house. The proposed 800 square foot guest house includes an attached
shed and covered porches; none of these structures will not encroach into any required
setbacks.
TRAFFIC COMMISSION REVIEW
Driveways
The proposed primary and secondary driveway aprons require review by the Traffic
Commission. The driveway request together with the project is scheduled for the March 24,
2022 Traffic Commission meeting. The City Council makes the final decision on the Traffic
40
Commission’s recommendations.

Landscape Plans).
Building Height and Pad Elevations (Pads 1 - 4)
The front upper west portion of the lot (Pad 1) will consist of a driveway and Zen garden and
2.5’ high walls and stairs. The stable and covered turnout in the front upper east portion of the
lot (Pad 2) will be 18’-3 5/16” in height; the ridgeline of the structures will be 5.2-feet below
Crest Road East. The new residence and the two attached garages (Pad 3) will be developed
on in the center of the lot and the maximum ridge height will be 15’-7 13/16”; the ridgeline of
these structures will be 16.8 feet below Crest Road East. The guest house, shed and covered
porches (Pad 3) will be 11’-8 11/16” in height; the ridgeline of the structure will be 21.2 feet
below Crest Road East. The lower rear portion of the lot (Pad 4) will consist of concrete stairs

Drainage
A natural drainage course is located along the western portion of the lot and a blue line
stream, which is a part of the Klondike Canyon System, is located approximately 200 feet
south of the southern property line of the lot. The lot is also located in proximity to the
Geotechnical Hazardous area of the City, known as the Flying Triangle. A 2016 geotechnical
and geological report for project site stated that the crown of a landslide (Flying Triangle) is
about 230 feet west of the southwestern portion of the lot.
The lot drains to the southwest and southeast of the property and the run-off from the main
building pad for the residence is proposed to be collected and stored in two cisterns that will
be located on the upper northeast portion of the lot under the driveway and two smaller
cisterns located on the lower pad. Two dissipaters are proposed on each building pad, on both
sides of the development (east and west) to help collect the overflow from the cisterns and to
filter stormwater from the building pads.
This project is subject to the Low Impact Development (LID) requirements pertaining to
stormwater management, including provisions for retention of run-off on the property.
The drainage design will collect and convey storm runoff from the project area to the northwest
corner and discharge into the street, (near the proposed driveway entry). Energy dissipation
will be provided to slow the discharge. Biofiltration unit and other LID best management
practices (BMPs) will be utilized, as required by the Building Department to treat and retain the
runoff. The rear portion of the lot will continue sheet flow to the rear (See Drainage Figure).
Utility Lines / Septic Tank
All utility lines for the development will be required to be placed underground. The Los
Angeles County Public Health department will review the septic system (location to be
determined).
Rolling Hills Community Association Review
Rolling Hills Community Association will review this project at a later date.
Public Participation

No calls or letters were received.
Issues of Concerns
Pad 1 in the northwestern corner of the lot shows a zen garden with 1,515 CY of grading.
Some of this grading is warranted for the driveway, however, the plan can be revised to
minimize the grading to keep as much of the natural topography as possible. This will be
consistent with the City's policy to maintain the existing grade.
There are certain details missing from the plans that need to be included. Plans for walls,
gates, a fountain, outdoor kitchen, fire pit, service yard, and other accessory structures need to
be provided.
Although the septic system needs to be revised by the Los Angeles County Public Health
department, the general location should be identified on the plan.
Environmental Review
The project has been determined to be categorically exempt pursuant to the California
Environmental Quality Act (CEQA) under Class 3, Section 15303. New construction of a
single-family residence and accessory structures.
RECOMMENDATION
It is recommended that the Planning Commission provide direction to the applicant and
continue the public hearing to occur after the Traffic Commission meeting on March 24, 2022.
SITE PLAN REVIEW CRITERIA
17.46.010 Purpose.
The site plan review process is established to provide discretionary review of certain
development projects in the City for the purposes of ensuring that the proposed project is
consistent with the City's General Plan; incorporates environmentally and aesthetically
sensitive grading practices; preserves existing mature vegetation; is compatible and consistent
with the scale, massing and development pattern in the immediate project vicinity; and
otherwise preserves and protects the health, safety and welfare of the citizens of Rolling Hills.
17.46.50 required findings.
1. The Commission shall be required to make findings in acting to approve, conditionally
approve, or deny a site plan review
2. 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
made:
3. The project complies with and is consistent with the goals and policies of the general
plan and all requirements of the zoning ordinance; 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;
4. The project is harmonious in scale and mass with the site, the natural terrain and
surrounding residences;
5. 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
44
trees, drainage courses and land forms (such as hillsides and knolls);
6. Grading has been designed to follow natural contours of the site and to minimize the
amount of grading required to create the building area;
7. Grading will not modify existing drainage channels nor redirect drainage flow, unless
such flow is redirected into an existing drainage course;
8. 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;
9. The project is sensitive and not detrimental to the convenient and safe movement of
pedestrians and vehicles; and
10. The project conforms to the requirements of the California Environmental Quality
CONDITIONAL USE PERMIT CRITERIA
17.42.50 Basis for approval or denial of conditional use permit.
The Commission (and Council on appeal), in acting to approve a conditional use permit
application, may impose conditions as are reasonably necessary to ensure the project is
consistent with the General Plan, compatible with surrounding land use, and meets the
provisions and intent of this title. In making such a determination, the hearing body shall find
that the proposed use is in general accord with the following principles and standards:
1. That the proposed conditional use is consistent with the General Plan;
2. That the nature, condition and development of adjacent uses, buildings and structures
have been considered, and that the use will not adversely affect or be materially
detrimental to these adjacent uses, building or structures;
3. That the site for the proposed conditional use is of adequate size and shape to
accommodate the use and buildings proposed;
4. That the proposed conditional use complies with all applicable development standards of
the zone district;
5. That the proposed use is consistent with the portions of the Los Angeles County
Hazardous Waste Management Plan relating to siting and siting criteria for hazardous
waste facilities;
6. That the proposed conditional use observes the spirit and intent of this title.

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:CONSIDER A POLICY FOR IMPLEMENTING EXPANDED LOW IMPACT
DEVELOPMENT STANDARDS
DATE:March 15, 2022
BACKGROUND:
On September 27, 2021, the City Council and Planning Commission held a joint study session
to discuss stormwater mitigation measures on private improvement projects. Staff gave a
presentation on stormwater harvesting, site design practices, and capital improvements
identified via future monitoring. Staff presented examples of permeable paving to improve
drainage by percolating rainwater into the ground, and the benefits of rain gardens and
bioswales. Staff indicated the City is projected to receive up to $100,000 per year in Safe
Clean Water municipal funds (Measure W) based on a parcel tax of 2.5 cents per square foot
of impermeable surface. These funds can be used to support low impact development (LID)
because they improve surface water quality by reducing stormwater runoff. So far the City has
been using these funds for water quality monitoring and planning, including the canyon
monitoring and hydrology study to document the City’s retention of the 85th%/24-hr storm
runoff. The funds could be used to distribute and install rain barrels, offer incentives to
property owners to replace impervious hardscape with permeable paving, and/or provide
offsets of the differential cost between impervious paving and permeable paving on
discretionary projects.
DISCUSSION:
LID is an approach to managing stormwater on development projects by retaining and
detaining stormwater onsite to preserve natural hydrology, thereby lessening adverse
downstream water quality impacts and simultaneously reducing flooding and erosion impacts
on downstream properties.
88
A fundamental element of LID is effective site design. Effective site design preserves and/or
creates natural landscape features that promote percolation of stormwater on-site, minimizes
impermeable surfaces that create runoff, and uses permeable paving for exterior paved
surfaces. Effective site design can be applied to all new and redevelopment projects during
planning and design in order to protect the natural canyon drainage system and downstream
properties and to support compliance with the municipal stormwater permit.
The following site design requirements are readily implemented without the need for advanced
hydrologic retention calculations or engineering services beyond what would be otherwise
undertaken for development projects, and can be applied to all new and redevelopment
projects:
1. At least 50% of new paved areas with slopes less than 10% to be constructed of
permeable surfaces.
2. Runoff from impermeable surfaces can be diverted to permeable surfaces as follows:
Show on plans that impermeable surfaces (e.g., driveways, roofs, and patios) drain
toward permeable paving or landscaped areas.
A minimum of 90% of impermeable surface areas to be routed toward permeable
paving and/or vegetated areas.
If runoff from impermeable surfaces is directed to landscaped areas
equipped with automatic irrigation systems, such irrigation systems shall be
furnished with a weather-based irrigation controller including a rain shut-off
sensor.
3. If runoff from roofs is collected via rain gutters and downspouts, either direct the runoff to
permeable paving surfaces or to one or more rain gardens following sizing guidelines in
South Bay Homeowner ’s Guide to Rainwater Harvesting. (Properties in the landslide
area are exempt from the requirement to install a rain garden to manage concentrated
flows from roofs and should consult a geotechnical engineer or geologist before doing
so.)
At the project applicant’s discretion, advanced stormwater management technologies that
require specialized engineering design services may be utilized for stormwater management
on new and redevelopment projects to address runoff from some or all of the project areas in
lieu of one or more of the foregoing requirements. Examples of advanced technologies
include:
4. Cisterns to harvest rainwater from roofs for beneficial use for irrigation require complex
design requirements, proper foundation design and/or soils report to support the load,
special plumbing permits and a water balance analysis.
5. Dry wells are an effective method for stormwater retention from impermeable surfaces;
however, they require a geotechnical report and percolation test and must be designed
by a professional engineer or geologist. Additionally, properties in the landslide area
should not install dry wells unless a licensed geotechnical engineer or geologist is
consulted and approves the design.
89
FISCAL IMPACT:
None.
RECOMMENDATION:
Discuss the item and direct staff on implementing a policy for expanding low impact
development.
