SUBJECT: RESOLUTION NO. 2005-35. A RESOLUTION OF THE
PLANNING COMMISSION OF THE CITY OF ROLLING HILLS
GRANTING APPROVAL FOR A SITE PLAN REVIEW FOR
GRADING AND CONSTRUCTION OF RETAINING WALLS TO
MEET SLOPE STABILITY REQUIREMENT AND DISTANCE
REQUIREMENT BETWEEN STRUCTURES AND TOE OF SLOPES,
AND A VARIANCE TO EXCEED THE MAXIMUM PERMITTED
DISTURBED AREA OF THE LOT AT A PROPERTY WHERE AN
APPROVAL WAS PREVIOUSLY GRANTED FOR GRADING
AND CONSTRUCTION AND WHERE DUE TO EXISTING
STRUCTURAL DEVELOPMENT RESTRICTION THIS PROJECT
REQUIRES PLANNING COMMISSION REVIEW, IN ZONING
CASE NO. 716, AT 40 EASTFIELD DRIVE, (LOT 91-EF),
(TONSICH).
1. The Planning Commission adopted Resolution No. 2005-35, which is
attached, on December 20, 2005 at their regular meeting granting approval in
Zoning Case No. 716. The vote was unanimous by those in attendance.
Commissioner Henke was absent due to illness.
2. In October 2002, the Planning Commission approved Zoning Case No. 653,
which the City Council took under jurisdiction. Ultimately, the City Council
upheld Planning Commission's decision to approve the application with a minor
modification allowing a lesser encroachment of the detached garage into the side
yard setback.
3. The previous approval consisted of construction of a 666 square foot
addition to an existing single family residence, a 596 square foot detached garage
to replace a 400 square foot unauthorized detached garage, an 800 square foot
guest house and a future stable; a Variance to permit the detached garage to
encroach 6 feet into the required side yard setback and the future stable into the
ZCNo.716 1
1,m Veal nn Hocyc:Ir,d I np' r
rear setback on a through lot; and Conditional Use Permits to construct the guest
house and the detached garage.
4. Prior to the project being approved by Los Angeles County Department of
Public Works and Building and Safety Divisions, the applicant was required to
conduct soils, geology and hydrology studies to assure lot stability for the
approved construction and siting for septic tank. The study determined that the
slopes below the proposed addition and below the proposed detached garage do
not meet the factor of stability required by the Los Angeles County Building
Code. In addition, the Los Angeles County Building Code requires a horizontal
setback of between 3 feet to 15 feet, depending on the grade of the slope, between
structures and the ascending slope. This requirement became effective after the
original approval for the structures was granted to the applicant.
5. The current application is proposed to address slope stability issues
identified during soil investigation on the property and to address County
Building Code requirements. The current application, although proposes the
walls discussed below, requires Planning Commission approval due to the
quantity of soil that must be moved (673 cubic yards of cut and fill, 60%
disturbance) to stabilize the site. The proposed walls are also part of the plan to
address slope stability on the site. Approval of this application will permit the
applicant to complete the previously approved development, stabilize the site and
meet County Building Code requirements.
6. Therefore, in order to satisfy the County requirements for slope stability,
the applicant is proposing to trim off a portion of the descending slope below the
existing residence and below the proposed detached garage to a flatter 2:1 slope,
and add planter walls, that would act as retaining walls starting 3 to 5 feet below
the top of slope. The walls will not exceed 5-feet in height. The applicant's
representative states that "introduction of the planter walls will reduce the run of
the slope, allowing a trimming of the unstable soil and provide the required 2:1
(H:V) slope, thus conforming to the 1.5 slope stability factor of safety".
7. In order to meet the distance requirements between the structures and the
ascending slope, the applicant proposes to introduce terraced retaining planter
walls, just as in the requirement to meet the factor of stability. The retaining walls
are proposed to be located above the detached garage, above the proposed
addition, and above the proposed quest house and will not exceed 5 feet in
height. According to the applicant's representative, the walls reinforce and
stabilize the slope and provide the required setback. No new structures are
proposed, except for the walls.
8. To accomplish the two tasks mentioned above (stability factor and distance
of structures to slope) 673 cubic yards of cut and 673 cubic yards of fill are
proposed to be moved, and will be balanced on site. Pursuant to the Zoning
Ordinance remedial grading is deemed disturbance of the lot. Previously 111
cubic yards of cut and 111 cubic yards of fill were approved for the construction.
This new grading activity triggers a requirement for a Variance to exceed the
maximum permitted disturbed area of the lot. 40% of disturbance was approved
ZC No. 716
• •
previously, which is the maximum permitted. This additional remedial work
would bring the disturbed area of the net lot to 60.0% and would create gentler
slopes of 2:1 (H:V) gradient.
9. The property is zoned RAS-1 and the gross lot area is 1.4 acres, (60,984
sq.ft.). The net lot area, as calculated for development purposes, is 39,664 square
feet. Access to this lot is through the neighboring property to the west. A ten -foot
driveway easement serving adjacent property to the southeast traverses along the
entire width of this lot. The two roadways easements, one off of Eastfield and the
second off of Outrider, the driveway leading to the neighbor's house plus ten feet
around the perimeter of the lot are deducted from the gross lot area for calculating
the net lot area for construction purposes.
10. There are two existing building pads on the property. The building pads are
not proposed to be enlarged to accommodate the previously approved
construction or the current request. The existing residential building pad outside
the required setbacks is 10,069 square feet and the guesthouse/stable pad outside
the required setbacks is 2,307 square feet. The residential building pad coverage
was approved at 40.8%, (existing is 35.3%), and the guesthouse/stable pad
coverage was approved at 54.2%, which includes the future stable.
11. The structural lot coverage was previously approved at 5,360 square feet or
13.5% of the net lot area (20% maximum permitted). Total lot coverage, including
structures, driveways, including the driveway serving the adjacent property, and
other paved areas / decking was approved at 11,783 square feet or 29.7% of the net
lot area (35% maximum permitted). With the introduction of 1,824 square feet of
planter retaining walls the structural lot coverage will increase to 18.1% and the
total lot coverage will increase to 34.3%, which is within the allowable
development standards.
12. The applicant's representative summarizes, in part, the request and
justification for a variance as follows:
"This request is made to satisfy the County of Los Angeles, Department of
Public Works, Geotechnical and Material Engineering Division requirements as
well as the Los Angeles County Building and Safety Division requirements to meet
the factor of safety for the subject hillside and the distance requirement between
structures and slopes. All City of Rolling Hills Codes defining planter wall heights
will be maintained and enforced. These improvements will improve the safety of
the hillside."
13. Some of the conditions required by the Planning Commission for this
project include that the above ground swale and dissipaters be of earth tone color
and be screened to the maximum extent feasible from the view of the neighbors
and from Outrider Road, that a landscaping plan and security deposit for the
landscaping of the graded areas be submitted to staff and that any further
development on the property be reviewed by the Planning Commission.

14. The Rolling Hills Community Association will review this project at a later
date.
15. The project has been determined to be categorically exempt pursuant to the
California Environmental Quality Act (CEQA).
RECOMMENDATION
It is recommended that the City Council receive and file the staff report or provide
other direction to staff.

RESOLUTION NO.2005-35
A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF
ROLLING HILLS GRANTING APPROVAL FOR A SITE PLAN REVIEW FOR
GRADING AND CONSTRUCTION OF RETAINING WALLS TO MEET SLOPE
STABILITY REQUIREMENT AND DISTANCE REQUIREMENT BETWEEN
STRUCTURES AND TOE OF SLOPES, AND A VARIANCE TO EXCEED THE
MAXIMUM PERMITTED DISTURBED AREA OF THE LOT AT A PROPERTY
WHERE AN APPROVAL WAS PREVIOUSLY GRANTED FOR GRADING AND
CONSTRUCTION AND WHERE DUE TO EXISTING STRUCTURAL
DEVELOPMENT RESTRICTION THIS PROJECT REQUIRES PLANNING
COMMISSION REVIEW, IN ZONING CASE NO. 716, AT 40 EASTFIELD
DRIVE, (LOT 91-EF), (TONSICH).
THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DOES
HEREBY FIND, RESOLVE AND ORDER AS FOLLOWS:
Section 1. Mr. Nicholas Tonsich duly filed applications with respect to
real property located at 40 Eastfield Drive, Rolling Hills (Lot 91-EF) requesting a
Site Plan Review for remedial grading and construction of walls, including walls
along the driveway, and a Variance to exceed the maximum permitted disturbed
net lot area.
Section 2. The Planning Commission conducted duly noticed public
hearings to consider the applications on October 18, 2005, November 15, 2005,
and at a field trip visit on November 15, 2005. The applicant was notified of the
public hearings in writing by first class mail. Evidence was heard and presented
from all persons interested in affecting said proposal and from members of the
City staff. The Planning Commission reviewed, analyzed and studied said
proposal. The applicant and his representatives were in attendance at the
hearings.
Section 3. The City Council, after taking jurisdiction of the case,
approved Zoning Case No. 653 on October 15, 2002, for a Site Plan Review to
permit construction of a 666 square foot addition to an existing single family
residence, to construct a 596 square foot detached garage to replace a 400 square
foot unauthorized detached garage, to construct an 800 square foot guest house
and a future stable; a Variance request to permit the detached garage to encroach
into the required side yard setback and the future stable into the rear setback on a
through lot; and Conditional Use Permits to construct the guest house and the
detached garage on subject property. The City Council also placed a condition on
the project that the Planning Commission reviews any future development on the
property.
Section 4. During the review process of the application by the Los
Angeles County Department of Public Works, the County required soils and
geology study for the property. The soils and geology study performed by the
applicant's geotechnical consultants revealed that the slopes below the proposed
addition and below the proposed detached garage do not meet the factor of
Reso. 2005-35
Tnncirh
• •
stability as required by the Los Angeles County Building Code. In addition, the
Los Angeles County Department of Building and Safety requires a horizontal
setback of between 3 feet to 15 feet, depending on the slope gradient, between
structures and the ascending slopes.
Section 5. In order to satisfy the County requirements for slope stability,
the applicant is proposing to trim off a portion of the descending slope below the
existing residence and below the proposed detached garage to a flatter 2:1 slope
gradient, and add planter walls, that would act as retaining walls starting 3 to 5
feet below the top of slope, not to exceed 5-feet in height. In order to meet the
distance requirements between the structures and the slope, the applicant
proposes to introduce terraced retaining planter walls. The retaining walls are
proposed to be located above the detached garage, above the proposed addition,
and above the proposed quest house and will not exceed 5 feet in height.
Section 6. To accomplish the requirement of slope stability and
distance of structures to slope, additional grading would be required, which
would triggers a requirement for a Variance to exceed the maximum permitted
disturbed area of the lot. Previous approval, (in Zoning Case No. 653), allowed
40% disturbance of the net lot area, which is the maximum permitted. This
additional remedial work would bring the disturbed area of the net lot to 23,980
square feet or 60.0%. A gentler slopes of 2:1 (H:V) gradient will result. In
addition, in order to provide an adequate turn around to the garage the
driveway will be re -graded and short walls constructed along both sides of the
driveway. The walls will range in height from a 6" curb to 3 feet.
Section 7. Section 17.46.020(A)(1) and (2) requires a Site Plan Review
for projects requiring a grading permit and for construction of structures, which
includes walls. With respect to the Site Plan Review application, the Planning
Commission makes the following findings of fact:
A. The proposed activity is compatible with the General Plan and the
Zoning Ordinance. The Land Use Element of the General Plan establishes the
maintenance of strict grading practices to preserve the community's natural
terrain. The Building Code and the Zoning Ordinance require a balanced cut and
fill ratio and do not permit import or export of soil, except under special
circumstances applicable to a property and with permission from the City
Manager. The General Plan also permits grading to remediate slopes.
B. The proposed activity preserves and integrates into the site design,
to the maximum extent feasible, existing natural topographic features of the lot
including surrounding vegetation, mature trees, and drainage courses. Although
grading of the existing slopes is necessary to correct slope stability and for
meeting the Code requirement for distance separation between structures and
slope, the resulting slope will be less steep and will meet City's requirements of a
2:1 gradient.
Reso. 2005-35

• •
C. The development plan follows natural contours of the site to the
maximum extent practicable. The natural drainage course will be preserved and
drainage will continue to be directed to the rear of the property.
D. The development plan will, based upon compliance with the
conditions contained in this Resolution, supplement the existing vegetation with
landscaping that is compatible with and enhances the rural character of the
community. Upon completion of the project the graded slopes will be re -
vegetated with native vegetation.
E. The development plan substantially preserves the natural and
undeveloped state of the lot by minimizing building coverage because no new
structures are proposed.
F. The proposed development is harmonious in scale and mass with
the site, the natural terrain and other residences on Eastfield Drive. This grading
is necessary to meet the required factor of stability of the slope of the property.
G. The proposed development is sensitive and not detrimental to the
convenience and safety of circulation for pedestrians and vehicles because the
proposed project will utilize the existing driveway access.
H. The project conforms to the requirements of the California
Environmental Quality Act.
Section 8. Sections 17.38.010 through 17.38.050 of the Rolling Hills
Municipal Code permit approval of a Variance from the standards and
requirements of the Zoning Ordinance 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. A
Variance to Section 17.16.070 (B) is required because it states that the lot
disturbance shall be limited. to 40.0% of the net lot area. The applicant is
requesting a Variance because total disturbance of the net lot area is proposed to
be 60.0%. With respect to this request for a Variance, the Planning Commission
finds as follows:
A. There are exceptional and extraordinary circumstances and conditions
applicable to the property or to the intended use that do not apply generally to
the other property or class of use in the same zone. The Variance for the total
disturbance is necessary because of the existence of poor soil condition, which if
not repaired will threaten the existing residence at 40 Eastfield Drive and the
property owner will not be able to construct the structures previously approved.
B. The Variance is necessary for the preservation and enjoyment of a
substantial property right possessed by other property in the same vicinity and
zone, but which is denied to the property in question. The Variance is necessary
because of the unusual situation on the lot. The property owner will not be able
Reso. 2005-35

• •
to improve his property, which does not allow the property owner a normal use
or to enjoy the property possessed by others in vicinity.
C. The granting of the Variance would not be materially detrimental to the
public welfare or injurious to the property or improvements in such vicinity and
zone in which the property is located. All grading and project repair will occur
within the property. The project as conditioned by this Resolution will be
adequately screened to prevent adverse visual impact to surrounding properties.
The proposed development will improve slope stability through the use of
approved drainage and buttressing of the slopes, and will permit the owners to
enjoy their property without deleterious infringement on the rights of
surrounding property owners.
Section 9. Based upon the foregoing findings and the evidence in the
record, the Planning Commission hereby approves the Site Plan Review for
grading and construction of walls, not to exceed 5-feet in height, except along the
driveway, and a Variance to exceed the maximum permitted disturbed (60%) net
lot area in Zoning Case No. 716, subject to the following conditions:

granted is otherwise extended pursuant to the requirements of these Sections.
B. It is declared and made a condition of the Site Plan Review and
Variance approvals, that if any conditions thereof are violated, this approval
shall be suspended and the privileges granted thereunder shall lapse; provided
that the applicants have been given written notice to cease such violation, the
opportunity for a hearing has been provided, and if requested, has been held,
and thereafter the applicant fails to correct the violation within a period of thirty
(30) days from the date of the City's determination.

A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF
ROLLING HILLS GRANTING APPROVAL FOR A SITE PLAN REVIEW FOR
GRADING AND CONSTRUCTION OF RETAINING WALLS TO MEET SLOPE
STABILITY REQUIREMENT AND DISTANCE REQUIREMENT BETWEEN
STRUCTURES AND TOE OF SLOPES, AND A VARIANCE TO EXCEED THE
MAXIMUM PERMITTED DISTURBED AREA OF THE LOT AT A PROPERTY

COMMISSION REVIEW, IN ZONING CASE NO. 716, AT 40 EASTFIELD
DRIVE, (LOT 91-EF), (TONSICH).
THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DOES
HEREBY FIND, RESOLVE AND ORDER AS FOLLOWS:
Section 1. Mr. Nicholas Tonsich duly filed applications with respect to
real property located at 40 Eastfield Drive, Rolling Hills (Lot 91-EF) requesting a
Site Plan Review for remedial grading and construction of walls, including walls
along the driveway, and a Variance to exceed the maximum permitted disturbed
net lot area.
Section 2. The Planning Commission conducted duly noticed public
hearings to consider the applications on October 18, 2005, November 15, 2005,
and at a field trip visit on November 15, 2005. The applicant was notified of the
public hearings in writing by first class mail. Evidence was heard and presented
from all persons interested in affecting said proposal and from members of the
City staff. The Planning Commission reviewed, analyzed and studied said
proposal. The applicant and his representatives were in attendance at the
hearings.
Section 3. The City Council, after taking jurisdiction of the case,
approved Zoning Case No. 653 on October 15, 2002, for a Site Plan Review to
permit construction of a 666 square foot addition to an existing single family
residence, to construct a 596 square foot detached garage to replace a 400 square
foot unauthorized detached garage, to construct an 800 square foot guest house
and a future stable; a Variance request to permit the detached garage to encroach
into the required side yard setback and the future stable into the rear setback on a
through lot; and Conditional Use Permits to construct the guest house and the
detached garage on subject property. The City Council also placed a condition on
the project that the Planning Commission reviews any future development on the
property.
Section 4. During the review process of the application by the Los
Angeles County Department of Public Works, the County required soils and
geology study for the property. The soils and geology study performed by the
applicant's geotechnical consultants revealed that the slopes below the proposed
addition and below the proposed detached garage do not meet the factor of
Reso. 2005-35
Tonsich
•
•
stability as required by the Los Angeles County Building Code. In addition, the
Los Angeles County Department of Building and Safety requires a horizontal
setback of between 3 feet to 15 feet, depending on the slope gradient, between
structures and the ascending slopes.
Section 5. In order to satisfy the County requirements for slope stability,
the applicant is proposing to trim off a portion of the descending slope below the
existing residence and below the proposed detached garage to a flatter 2:1 slope
gradient, and add planter walls, that would act as retaining walls starting 3 to 5
feet below the top of slope, not to exceed 5-feet in height. In order to meet the
distance requirements between the structures and the slope, the applicant
proposes to introduce terraced retaining planter walls. The retaining walls are
proposed to be located above the detached garage, above the proposed addition,
and above the proposed quest house and will not exceed 5 feet in height.
Section 6. To accomplish the requirement of slope stability and
distance of structures to slope, additional grading would be required, which
would triggers a requirement for a Variance to exceed the maximum permitted
disturbed area of the lot. Previous approval, (in Zoning Case No. 653), allowed
40%, disturbance of the net lot area, which is the maximum permitted. This
additional remedial work would bring the disturbed area of the net lot to 23,980
square feet or 60.0%. A gentler slopes of 2:1 (H:V) gradient will result. In
addition, in order to provide an adequate turn around to the garage the
driveway will be re -graded and short walls constructed along both sides of the
driveway. The walls will range in height from a 6" curb to 3 feet.
Section 7. Section 17.46.020(A)(1) and (2) requires a Site Plan Review
for projects requiring a grading permit and for construction of structures, which
includes walls. With respect to the Site Plan Review application, the Planning
Commission makes the following findings of fact:
A. The proposed activity is compatible with the General Plan and the
Zoning Ordinance. The Land Use Element of the General Plan establishes the
maintenance of strict grading practices to preserve the community's natural
terrain. The Building Code and the Zoning Ordinance require a balanced cut and
fill ratio and do not permit import or export of soil, except under special
circumstances applicable to a property and with permission from the City
Manager. The General Plan also permits grading to remediate slopes.
B. The proposed activity preserves and integrates into the site design,
to the maximum extent feasible, existing natural topographic features of the lot
including surrounding vegetation, mature trees, and drainage courses. Although
grading of the existing slopes is necessary to correct slope stability and for
meeting the Code requirement for distance separation between structures and
slope, the resulting slope will be less steep and will meet City's requirements of a
2:1 gradient.
Reso. 2005-35

z�
• •
C. The development plan follows natural contours of the site to the
maximum extent practicable. The natural drainage course will be preserved and
drainage will continue to be directed to the rear of the property.
D. The development plan will, based upon compliance with the
conditions contained in this Resolution, supplement the existing vegetation with
landscaping that is compatible with and enhances the rural character of the
community. Upon completion of the project the graded slopes will be re -
vegetated with native vegetation.
E. The development plan substantially preserves the natural and
undeveloped state of the lot by minimizing building coverage because no new
structures are proposed.
F. The proposed development is harmonious in scale and mass with
the site, the natural terrain and other residences on Eastfield Drive. This grading
is necessary to meet the required factor of stability of the slope of the property.
G. The proposed development is sensitive and not detrimental to the
convenience and safety of circulation for pedestrians and vehicles because the
proposed project will utilize the existing driveway access.
H. The project conforms to the requirements of the California
Environmental Quality Act.
Section 8. Sections 17.38.010 through 17.38.050 of the Rolling Hills
Municipal Code permit approval of a Variance from the standards and
requirements of the Zoning Ordinance 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. A
Variance to Section 17.16.070 (B) is required because it states that the lot
disturbance shall be limited to 40.0% of the net lot area. The applicant is
requesting a Variance because total disturbance of the net lot area is proposed to
be 60.0%. With respect to this request for a Variance, the Planning Commission
finds as follows:
A. There are exceptional and extraordinary circumstances and conditions
applicable to the property or to the intended use that do not apply generally to
the other property or class of use in the same zone. The Variance for the total
disturbance is necessary because of the existence of poor soil condition, which if
not repaired will threaten the existing residence at 40 Eastfield Drive and the
property owner will not be able to construct the structures previously approved.
B. The Variance is necessary for the preservation and enjoyment of a
substantial property right possessed by other property in the same vicinity and
zone, but which is denied to the property in question. The Variance is necessary
because of the unusual situation on the lot. The property owner will not be able
Reso. 2005-35
Tnnsirh
•
•
to improve his property, which does not allow the property owner a normal use
or to enjoy the property possessed by others in vicinity.
C. The granting of the Variance would not be materially detrimental to the
public welfare or injurious to the property or improvements in such vicinity and
zone in which the property is located. All grading and project repair will occur
within the property. The project as conditioned by this Resolution will be
adequately screened to prevent adverse visual impact to surrounding properties.
The proposed development will improve slope stability through the use of
approved drainage and buttressing of the slopes, and will permit the owners to
enjoy their property without deleterious infringement on the rights of
surrounding property owners.
Section 9. Based upon the foregoing findings and the evidence in the
record, the Planning Commission hereby approves the Site Plan Review for
grading and construction of walls, not to exceed 5-feet in height, except along the
driveway, and a Variance to exceed the maximum permitted disturbed (60%) net
lot area in Zoning Case No. 716, subject to the following conditions:

granted is otherwise extended pursuant to the requirements of these Sections.
B. It is declared and made a condition of the Site Plan Review and
Variance approvals, that if any conditions thereof are violated, this approval
shall be suspended and the privileges granted thereunder shall lapse; provided
that the applicants have been given written notice to cease such violation, the

OCTOBER 8, 2005
Request for a Site Plan Review for grading and construction of retaining walls to
meet slope stability requirements and distance requirement between structures
and toe of slope and a Variance to exceed the maximum permitted disturbed area
of the lot at a property where an approval was previously granted for grading and
construction of an addition to an existing residence, a guest house, a detached
garage and a future stable.
BACKGROUND
1. The Planning Commission visited the site earlier today.
2. The Planning Commission approved Zoning Case No. 653 on October 15,
2002, for a Site Plan Review to permit construction of a 666 square foot addition to
an existing single family residence, to construct a 596 square foot detached garage
to replace a 400 square foot unauthorized detached garage, to construct an 800
square foot guest house and a future stable; a Variance request to permit the
detached garage to encroach into the required side yard setback and the future
stable into the rear setback on a through lot; and Conditional Use Permits to
construct the guest house and the detached garage on subject property.
3. On October 21, 2002 the City Council took Zoning Case No. 653 under
jurisdiction, and ultimately upheld Planning Commission's decision with a minor
modification allowing a lesser encroachment of the detached garage into the side
yard setback.
4. During the review stage of the approval process by the Los Angeles
County Department of Public Works, the applicant was required to conduct soils
and geology studies to assure lot stability for the approved construction. The
ZC 716
Dln('nmm 11/1VAC

• •
study determined that the slope below the proposed addition and below the
proposed detached garage does not meet the factor of safety required by the Los
Angeles County Building Code. In addition, the Los Angeles County Department
of Building and Safety requires a horizontal setback of between 3 feet to 15 feet,
depending on the slope gradient, between structures and the ascending slope.
5. In order to satisfy the County requirements for slope stability, the applicant
is proposing to trim off a portion of the descending slope below the existing
residence and below the proposed detached garage to a flatter 2:1 slope gradient,
and add planter walls, that would act as retaining walls starting 3 to 5 feet below
the top of slope, not to exceed 5-feet in height. The applicant's representative
states that "introduction of the planter walls will reduce the run of the slope,
allowing a trimming of the unstable soil and provide the required 2:1 (H:V) slope,
thus conforming and guaranteeing the 1.5 slope stability factor of safety".
6. In order to meet the distance requirements between the structures and the
slope, the applicant proposes to introduce terraced retaining planter walls, just as
in the requirement to meet the factor of stability. The retaining walls are proposed
to be located above the detached garage, above the proposed addition, and above
the proposed quest house and will not exceed 5 feet in height. According to the
applicant's representative, the walls reinforce and stabilize the slope and provide
the required setback. The lot is a through lot and the setback from the rear
roadway easement is 50-feet. No new structures are proposed, except for the
walls.
7. To accomplish the two tasks mentioned above (stability factor and distance
of structures to slope) 673 cubic yards of cut and 673 cubic yards of fill are
proposed to be moved, and will be balanced on site. Pursuant to the Zoning
Ordinance remedial grading is deemed disturbance of the lot. Previously 111
cubic yards of cut and 111 cubic yards of fill were approved for the construction.
This new grading activity triggers a requirement for a Variance to exceed the
maximum permitted disturbed area of the lot. Previous approval allowed 40%
disturbance of the net lot area, which is the maximum permitted. This additional
remedial work would bring the disturbed area of the net lot to 23,980 square feet
or 60.0% and will create gentler slopes of 2:1 (H:V) gradient.
8. The.property is zoned RAS-1 and the gross lot area is 1.4 acres, (60,984
sq.ft.). The net lot area, as calculated for development purposes, is 39,664 square
feet. Access to this lot is through the neighboring property to the west. The subject
lot is a through lot, with two frontages, Eastfield Drive and Outrider Road. A ten -
foot driveway easement serving adjacent property to the southeast traverses along
the entire width of this lot. All of these roadway easements, the driveway leading
to the neighbor's house plus ten feet around the perimeter of the lot, are deducted
from the gross lot area for calculating the net lot area.
9. There are two existing building pads on the property. The residential
building pad is not proposed to be enlarged to accommodate the previously
approved construction or the current request. The existing residential building pad
outside the required setbacks is 10,069 square feet and the guesthouse/stable pad
ZC 716
PI n Cn„,... 1 1 / 14 /(K
2
• •
outside the required setbacks is 2,307 square feet. The residential building pad
coverage was approved to be 40.8%, (existing is 35.3%), and the guesthouse/stable
pad coverage was approved at 54.2%, which includes the future stable.
10. The structural lot coverage was previously approved at 5,360 square feet or
13.5% of the net lot area (20% maximum permitted). Total lot coverage, including
structures, driveways, including the driveway serving the adjacent property, and
other paved areas/decking was approved at 11,783 square feet or 29.7% of the net
lot area (35% maximum permitted). With the introduction of 1,824 square feet of
planter retaining walls the structural lot coverage will increase to 18.1% and the
total lot coverage will increase to 34.3%, which is within the allowable
development standards.
11. The applicant's representative summarizes, in part, the request and
justification for a variance as follows:
"This request is made to satisfy the County of Los Angeles, Department of
Public Works, Geotechnical and Material Engineering Division requirements as
well as the Los Angeles County Building and Safety Division requirements to meet
the factor of safety for the subject hillside and the distance requirement between
structures and slopes. All City of Rolling Hills Codes defining planter wall heights
will be maintained and enforced. These improvements will improve the safety of
the hillside, thus guaranteeing public safety and safeguard from injury."
12. The applicant submitted a preliminary drainage plan. The Planning
Commission may impose a condition, if this project is approved, that the above
ground swales and dissipaters be of earth tone color and be screened to maximum
extent feasible from the view of the neighbors and from Outrider Road.
13. The Rolling Hills Community Association will review this project at a later
date.
14. The project has been determined to be categorically exempt pursuant to the
California Environmental Quality Act (CEQA).
RECOMMENDATION
It is recommended that the Planning Commission open the continued public
hearing, take public testimony and provide direction to staff.

ZONING CASE NO. 716
40 EASTFIELD DRIVE (LOT 91-EF)
RAS-1, 1.4 ACRES (GROSS)
MR. NICHOLAS TONSICH
JERRY RODIN, ARCHITECT
OCTOBER 8, 2005
Request for a Site Plan Review for grading to meet slope stability requirements
and a Variance to exceed the maximum permitted disturbed area of the lot at a
property where an approval was previously granted for grading and construction
of an addition to an existing residence, a guest house, a detached garage and a
future stable at 40 Eastfield Drive.
BACKGROUND
1. The Planning Commission approved Zoning Case No. 653 on October 15,
2002, for a Site Plan Review to permit construction of a 666 square foot addition to
an existing single family residence, to construct a 596 square foot detached garage
to replace a 400 square foot unauthorized detached garage, to construct an 800
square foot guest house and a future stable; a Variance request to permit the
detached garage to encroach into the required side yard setback and the future
stable into the rear setback on a through lot; and Conditional Use Permits to
construct the guest house and the detached garage on subject property.
2. On October 21, 2002 the City Council took Zoning Case No. 653 under
jurisdiction, and ultimately upheld Planning Commission's decision with a minor
modification allowing a lesser encroachment of the detached garage into the side
yard setback.
3. During the review stage of the approval process by the Los Angeles
County Department of Public Works, the applicant was required to conduct soils
and geology studies to assure lot stability for the approved construction. The
study determined that the slope below the proposed addition and below the
proposed detached garage does not meet the factor of safety required by the Los
Angeles County Building Code. In addition, the Los Angeles County Department
ZC 716
Pin rnmm 1A/19/M
Printed on H.:.yr;fr:d f';r•wv
of Building and Safety requires a horizontal setback of between 3 feet to 15 feet,
depending on the slope gradient, between structures and the ascending slope.
4. In order to satisfy the County requirements for slope stability, the applicant
is proposing to trim off a portion of the descending slope below the existing
residence and below the proposed detached garage to a flatter 2:1 slope gradient,
and add planter walls starting 3 to 5 feet below the top of slope, not to exceed 5-
feet in height. The applicant's representative states that "introduction of the
planter walls will reduce the run of the slope, allowing a trimming of the unstable
soil and provide the required 2:1 (H:V) slope, thus conforming and guaranteeing
the 1.5 slope stability factor of safety".
5. In order to meet the distance requirements between the structures ,and the
slope, the applicant proposes to introduce terraced planter walls, just as in the
requirement to meet the factor of stability. According to the applicant's
representative, the walls reinforce and stabilize the slope and provide the
required setback. The lot is a through lot and the setback from the rear roadway
easement is 50-feet.
6. To accomplish the two tasks mentioned above (stability factor and. distance
of structures to slope) 673 cubic yards of cut and 673 cubic yards of fill are
proposed to be moved, and will be balanced on site. Pursuant to the )Zoning
Ordinance remedial grading is deemed disturbance of the lot. Previously 111
cubic yards of cut and 111 cubic yards of fill were approved for the construction.
This new grading activity triggers a requirement for a Variance to exceed the
maximum permitted disturbed area of the lot. Previous approval allowed 40%
disturbance of the net lot area, which is the maximum permitted. This additional
remedial work would bring the disturbed area of the net lot to 23,980 square feet
or 60.0%.
7. The property is zoned RAS-1 and the gross lot area is 1.4 acres, (60,984
sq.ft.). The net lot area, as calculated for development purposes, is 39,664 square
feet. Access to this lot is through the neighboring property to the west. The subject
lot is a through lot, with two frontages, Eastfield Drive and Outrider Road. A ten -
foot driveway easement serving adjacent property to the southeast traverses along
the entire width of this lot. All of these roadway easements, the driveway leading
to the neighbor's house plus ten feet around the perimeter of the lot, are deducted
from the gross lot area for calculating the net lot area.
8. There are two existing building pads on the property. The residential
building pad is not proposed to be enlarged to accommodate the previously
approved construction or the current request. The existing residential building pad
outside the required setbacks is 10,069 square feet and the guesthouse/stable pad
outside the required setbacks is 2,307 square feet. The residential building pad
coverage was approved to be 40.8%, (existing is 35.3%), and the guesthouse/ stable
pad coverage was approved at 54.2%, which includes the future stable.
9. The structural lot coverage was previously approved at 5,360 square feet or
13.5% of the net lot area (20% maximum permitted). Total lot coverage, including
structures, driveways, including the driveway serving the adjacent property, and
ZC 716

other paved areas / decking was approved at 11,783 square feet or 29.7% of the net
lot area (35% maximum permitted). With the introduction of 1,824 square feet of
planter walls the structural lot coverage will increase to 18.1% and the total lot
coverage will increase to 34.3%, which is within the allowable development
standards.
10. The applicant's representative summarizes, in part, the request and
justification for a variance as follows:
"This request is made to satisfy the County of Los Angeles, Department of
Public Works, Geotechnical and Material Engineering Division requirements as
well as the Los Angeles County Building and Safety Division requirements to meet
the factor of safety for the subject hillside and the distance requirement between
structures and slopes. All City of Rolling Hills Codes defining planter wall heights
will be maintained and enforced. These improvements will improve the safety of
the hillside, thus guaranteeing public safety and safeguard from injury."
11. The Rolling Hills Community Association will review this project at a later
date.
12. The project has been determined to be categorically exempt pursuant to the
California Environmental Quality Act (CEQA).
RECOMMENDATION
It is recommended that the Planning Commission review the staff report, open the
public hearing and take public testimony.
