NEALIS, CITY MANAGER FROM: YOLANTA SCHWARTZ, PLANNING DIRECTOR • INCORPORATED JANUARY 24, 1957 NO. 2 PORTUGUESE BEND ROAD ROLLING HILLS, CALIF. 90274 (310) 377-1521 FAX: (310) 377-7288 E-mail: cityofrh@aol.com Agenda Item No.: 4A Mtg. Date: 1 / 9 / 06 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. ZC No. 716 • • 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.

ZC No. 716 7 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 Tnncicrh 2 • • 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 Toncic,h 3 • • 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: A.

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 Tnnsich 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: A.

SITE LOCATION: ZONING AND SIZE: APPLICANT: REPRESENTATIVE: PUBLISHED: REQUEST 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 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 'o 4�J Printed on Recycled ' ip n. • • 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.

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 PI rnmm 1f1/152HK 2� 2 • • 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.
