Date: 01-10-11 DATE: JANUARY 10,2011 TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL FROM: YOLANTA SCHWARTZ, PLANNING DIRECTOR I • THROUGH: ANTON DAHLERBRUCH, CITY MANAGER \()1) SUBJECT: RESOLUTION NO. 2010-30. A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS IN ZONING CASE 757 MODIFICATION GRANTING MODIFICATIONS TO A PREVIOUSLY APPROVED SITE PLAN REVIEW FOR SUBSTANTIAL GRADING FOR SLOPE STABILIZATION AND CONSTRUCTION OF A SINGLE FAMILY RESIDENCE ON A VACANT PARCEL OF LAND AT 3 APPALOOSA LANE (LOT 246-MS), ROLLING HILLS, CA. (FOZOONMEHR). A MITIGATED NEGATIVE DECLARATION WAS ADOPTED FOR THE PREVIOUSLY APPROVED PROJECT. RECOMMENDATION 1. It is recommended that the City Council receive and file this report or provide other direction to staff. REQUEST AND PLANNING COMMISSION ACTION 2. The property owners requested a modification to a previously approved Site Plan Review, which consisted of substantial grading (150,000 cubic yards of cut and 150,000 cubic yards of fill of soil) to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and on two adjacent lots developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive,and grading and construction of a new single family residence with garage and basement, swimming pool and a stable. The modification entails reducing the limits of grading by 18,000 square feet by not grading on adjacent lots, and instead, to construct 20 caissons along a portion of the ZC NO.757 Mod. 410 i i • westerly property line and to reduce the surficial grading quantities by over 17,400 cubic yards of cut and fill. In addition, a drainage terrace with a not to exceed 4.5-foot high wall is planned to be constructed, as is required by the Los Angeles County Drainage Engineer. The applicants have also requested that the Planning Commission waive one of the originally imposed conditions of approval, which requires that a third party consultant be hired by the City, at the owners' expense, to oversee the project. A Mitigated Negative Declaration was adopted for the previously approved project. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. 3. The Planning Commission approved the request unanimously with standard findings of facts and conditions of approval and with the following additional conditions: • That the property line be staked in the area of the caissons throughout the construction process • The resolution includes all of the conditions from the originally approved project. (Resolution 2008-15), including the mitigation measures and conditions relative to the modification request. • All references to grading on adjacent lots and conditions related thereto were excluded from the language of the resolution. • That any further development on the lot may be permitted with Planning Commission review • That the applicants comply with the Waste Diversion and the Water Efficient Landscape Ordinances. BACKGROUND 4. In 2008 the Planning Commission approved a Site Plan Review request to construct an 8,990 square foot residence, 2,050 square foot garage, 462 square feet covered porches, 820 square foot swimming pool, 36 square foot barbecue, 1,264 square feet water feature, 672 square foot future stable with corral and a service yard. A 6,423 square foot basement, 11 feet deep, was also approved. The approved construction required grading and slope stabilization to correct landslide condition on the subject lot and on two adjacent lots at 17 and 19 Buggy Whip Drive. 5. Since the 2008 approval, one of the adjacent property owners, on whose property minor grading was required, withdrew their agreement to allow the applicant to enter their property and conduct stabilization. The applicants, in order to pursue approvals for a new residence, were required to revise their plans to meet the building code requirements for lot stabilization in order to develop the lot. The applicants have therefore proposed to construct caissons along the common property line with their neighbors. The applicants submitted the revised soils, geology and caissons plans to the County and the proposed method of stabilization of the area of construction was approved. The applicants have also submitted a drainage plan to the County, which was reviewed and returned for minor corrections. The plan will need to be re-submitted (with the corrections).to the County drainage engineer. One of the corrections is to provide a drainage terrace along the eastern potion of the lot, which also requires a ZC NO.757 Mod • short wall. The RHCA Architectural Committee approved the residence and construction plans were submitted to the County Building and Safety Department for plan check. 6. The property is zoned RAS-2 and is 9.20 acres (gross) in size and 8.20 acres net, as calculated for development. The lot is currently vacant. Subject lot is irregular in shape with Appaloosa Lane located along the long portion of the lot. 7. Although the property is large, due to the terrain, less than 15% of the property is developable. The areas not proposed for development, and not of need of grading to correct a landslide condition, will remain in current state with mature trees and native and non-native vegetation interspersed throughout this area. Portion of this area will be re-vegetated with native plants, as required as part of the original approval. 8. A new driveway from Appaloosa Lane was approved by the Planning and Traffic Commissions. Access to the future stable will be through an access road not to exceed 25% in slope, and will connect to existing trails and to Appaloosa Lane. A new bridle trail will be constructed near Appaloosa Lane to connect to SI'S trail and another one will be constructed along the western portion of the property to connect to the Glory trail. 9. Recently, the Planning Commission granted the applicants an extension of time to commence the grading and construction. 10. One of the conditions of the original approval requires as follows: "The applicant shall reimburse the City for the cost of an independent construction consultant who shall be hired by the City to act as a construction relations officer to monitor the construction activity, including resolution of issues related to implementation of mitigation measures for this project and to assure that all of the conditions of this approval are being complied with. The applicant shall reimburse the City for the actual direct costs of the consultant plus 20% of the consultant's costs as administrative overhead". The applicants requested that this condition be deleted as they feel the scope of work has diminished where no grading will be done on adjacent lots as well as County's staff oversight of all projects have increased. The applicants' agent also stated that the General Contractor would have a job superintendent on site. MUNICIPAL CODE COMPLIANCE 11. Since submitting the grading, drainage, soils and geology reports and plans to the County, minor modifications were made to the plans. Grading for the residential building pad will require 11,200 cubic yards of cut and 7,940 cubic yards of fill (previously 9,420 cubic yards of cut soil and 9,420 cubic yards of fill). For the landslide remediation and buttress fill (key) construction it is estimated that 121,440 cubic yards of cut and same amount of fill will be necessary. (Previously, grading for stabilization of the entire slide, including the adjacent lots and the building pad, were approved at 150,000 cubic yards of cut and 150,000 c.y. of fill). The total grading will be reduced by over 17,400 cubic yards, each cut and fill. It is anticipated that no more than 2,990 cubic ZC NO.757 Mod • yards of dirt from the basement would be exported. However, depending on the shrinkage of the dirt, the basement dirt may have to be used on site. The applicant is proposing to excavate the failed slope area and replace it with a buttress fill keyed through the ancient slope failure mass, (re-compact using the same material). A buttress is a tightly compacted fill that acts like a retaining wall and is designed to hold land movement.The grading will be done in slots to avoid excessive stockpiling of soil.. 12. Storm drainage system will be installed consisting of two swales located on the remediated areas and a swale behind the retaining wall of the building pad. The County drainage engineer requires a drainage terrace to be located to the east of the residence. The terrace construction requires a 4.5 high wall. A MSE (Mechanically Stabilized Earth) wall with geogrid is proposed for that location and will be planted. Subdrains and catch basins will be constructed throughout the project. A dissipater is planned near the north-easterly property line. 13. A wall, varying in height between 6" curb to 5 feet is proposed to be constructed along the residential building pad and along a portion of the driveway, which was previously approved. 14. With this modification the applicants are now not proposing to construct the water features or stable and corral, that were previously approved, but to set aside an area for a future stable and corral and for calculations purposes show a future 450 square foot stable. The applicants representative shows.a minimum of 1,200 square foot stable pad, which would require 72 cubic yards of grading and a maximum 2,560 square foot set aside area, which would require 143 cubic yards of grading. The net lot area of the lot is 357,280 square feet, (8.2 acres). Two building pads are proposed. The residential building pad is proposed to be 38,080 square feet and will have coverage of 12,502 square feet or 32.8% and with allowances the coverage will be 12,004 or 31.5%. Coverage on the 1,200 square foot future stable pad is proposed at 450 square feet or 37.5%, (on a 2,560 square foot pad, the coverage would be 17.6%). Construction of a stable would require a Conditional Use Permit and would therefore be reviewed by the Planning Commission and the neighbors would have the opportunity to comment on the proposal. 15. The structural net lot coverage proposed is 12,952 square feet or 3.6% (previously 13,638 square feet or 3.8%), which includes all the structures and future 450 s.f. stable. (20% permitted); and the total lot coverage proposed including the structures and • paved areas is 27,180 sq.ft. or 7.6% (previously 27,296 square feet or 7.6%), (35% permitted). 16. Disturbed area for this project will be 119,560 square feet or 33.5%, and with future stable 117,620 square feet or 34.3%. (Previously the disturbance for this lot was approved at 32.3%). Disturbance includes any remedial grading (temporary disturbance), any graded slopes and building pad areas, and any nongraded area where impervious surfaces will remain or are proposed to be added. ZC NO.757 Mod 411 • 17. The Glory Trail traverses the rear easement on the property and will be affected by the repairs. It is required that the applicants restore the trail to the satisfaction of RHCA. 18. As a condition of approval, the utility lines to the structures will be placed underground; the roof material will meet City's standards and all other City and County requirements for construction will be met. ENVIRONMENTAL MITIGATION MEASURES ENVIRONMENTAL REVIEW 19. Pursuant to the requirements of the California Environmental Quality Act, (CEQA), staff prepared an Initial Environmental Study for the original proposal. The study identified environmental factors, which would be potentially affected by the proposed project. Those impacts included air quality due to substantial grading; biological resources due to habitat modification; geology and soils due to the extensive grading; hydrology due to substantially altering of existing drainage pattern; noise generated during construction; and traffic generated during construction. A Mitigated Negative Declaration was adopted for the previously approved project. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. The mitigation measures together with the conditions of the original approval (Resolution No. 2008-15), which are applicable, are incorporated into a modified Resolution. CONCLUSION 20. This approval is conditioned on the applicant obtaining the appropriate approvals from the County, the CA Department of Fish and Game, Regional Water Quality Control Board, AQMD and other agencies. The applicant requested that the condition requiring him to hire a third party project manager be waived, as there are many agencies that will be overseeing this project and the general contractor will have a superintendent who will be available at all times. 21. Staff deemed the proposed construction of caissons, elimination of the grading on adjacent lots, the proposed wall construction behind the terrace and the request to waive one of the conditions of approval as "major" modifications, and therefore required that the applicant submit this application to the Planning Commission. ZC NO.757 Mod • • , 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. 17.46.050 Required findings. A. The Commission shall be required to make findings in acting to approve, conditionally approve, or deny a site plan review application.. B. 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: 1. The project complies with and is consistent with the goals and policies of the general plan and all requirements of the zoning ordinance; 2. The project substantially preserves the natural and undeveloped state of the lot by minimizing building coverage. Lot coverage requirements are regarded as maximums, and the actual amount of lot coverage permitted depends upon the existing buildable area of the lot; 3. The project is harmonious in scale and mass with the site, the natural terrain and surrounding residences; 4. The project preserves and integrates into the site design, to the greatest extent possible, existing topographic features of the site, including surrounding native vegetation, mature trees, drainage courses and land forms (such as hillsides and knolls); • 5. Grading has been designed to follow natural contours of the site and to minimize the amount of grading required to create the building area; 6. Grading will not modify existing drainage channels nor redirect drainage flow, unless such flow is redirected into an existing drainage course; 7. The project preserves surrounding native vegetation and mature trees and supplements these elements with drought-tolerant landscaping which is compatible with and enhances the rural character of the community, and landscaping provides a buffer or transition area between private and public areas; 8. The project is sensitive and not detrimental to the convenient and safe movement of pedestrians and vehicles; and 9. The project conforms to the requirements of the California Environmental Quality Act. SOURCE: City of Rolling Hills Zoning Ordinance ZC NO.757 Mod -6- • RESOLUTION NO. 2010-30 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS IN ZONING CASE 757 MODIFICATION GRANTING MODIFICATIONS TO A PREVIOUSLY APPROVED SITE PLAN REVIEW FOR SUBSTANTIAL GRADING FOR SLOPE STABILIZATION AND CONSTRUCTION OF A SINGLE FAMILY RESIDENCE ON A VACANT PARCEL OF LAND AT 3 APPALOOSA LANE (LOT 246-MS), ROLLING HILLS, CA. (FOZOONMEHR). A MITIGATED NEGATIVE DECLARATION WAS ADOPTED FOR THE PREVIOUSLY APPROVED PROJECT. THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DOES HEREBY FIND, RESOLVE AND ORDER AS FOLLOWS: Section 1. An application was duly filed by Dr.• and Mrs. Shahran Fozoonmehr with respect to real property located at 3 Appaloosa Lane, (Lot 246-MS), Rolling Hills, CA requesting modification to previously approved Site Plan Review consisting of substantial grading (150,000 cubic yards of cut and 150,000 cubic yards of fill of soil) to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and . on two adjacent lots developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive, and grading and construction of a single family residence with garage and basement, swimming pool and a stable. The modification entails reducing the limits of grading by 18,000 square feet by not grading on adjacent lots, and instead, to construct 20 caissons along a portion of the westerly property line and to reduce the surficial grading quantities by a total of over 17,400 cubic yards. In addition, a drainage terrace with a not to exceed 4.5-foot high wall is planned to be constructed, as is required by the Los Angeles County Drainage Engineer. The applicants have also requested that the Planning Commission waive one of the originally imposed conditions of approval, which requires that a third party consultant be hired by the City, at the owners' expense, to oversee the project. Section 2. A Mitigated Negative Declaration was adopted for the previously approved project. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. Section 3. The Planning Commission conducted duly noticed public hearings to consider the application on November 16, 2010. The applicants were 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 and the Planning Commission having reviewed, analyzed and studied said proposal. The applicants and their representatives were in attendance at the hearing. 0 • ' • C Section 4. The property is zoned RAS-2 and is 9.20 acres (gross) in size and 8.20 acres net. The lot is currently vacant. Subject lot is irregular in shape. Portion of Appaloosa Lane is located within the property and does not follow the roadway easement line. Geological studies show an ancient landslide underlying the subject lot and two adjacent lots at 17 and 19 Buggy Whip Drive. To date the lot did not experience any visible earth movement. The proposed construction requires grading and slope stabilization to correct the ancient landslide condition on the subject lot and installation of caissons along the common property lines with the adjacent lots (17 and 19 Buggy Whip). No grading is proposed on the adjacent lots. Section 5. The applicant is proposing to excavate the slope failure area/ancient landslide and replace it with a buttress fill keyed through the ancient slope failure mass. A buttress fill is proposed along the easterly side of the property. A buttress is a tightly compacted fill that acts like a retaining wall and is designed to hold the movement. The grading will be done in progressive slots to avoid stockpiling of soil. Sub-drains drain pipes and catch basins will be installed throughout the project to protect the lot from water erosion. A drainage terrace with a 4.5-foot high plantable wall will also be constructed. Section 6. In 2003, the Planning Commission and the City Council approved an application for the same size development, except that the slope remediation portion of the application was smaller in scope and size. During the detailed soils and geology investigation required by the Los Angeles County Public Works Department for the actual grading of the approved project in 2003, it was determined that the previously delineated ancient landslide extended further than originally found. The 2003 approval expired, and in 2008 the Planning Commission approved same application as in 2003, for an 8,990 square foot residence, 2,050 square foot garage, 462 square feet covered porches, 820 square foot swimming pool, 36 square foot barbecue, 1,264 square feet water feature, 672 square foot future stable with corral and a service yard. A 6,423 square foot basement was also approved. The approved construction required grading and slope stabilization to correct landslide condition on the subject lot and on two adjacent lots at 17 and 19 Buggy Whip Drive. Section 7. Since the 2008 approval, one of the adjacent property owners, on whose property grading was required, withdrew their agreement to allow the applicant to enter their property and conduct stabilization. The applicants, in order to pursue approvals for a new residence, were required to revise their plans to meet the building code requirements for lot stabilization in order to develop the lot. The applicants have therefore proposed to construct caissons along the common property line with their neighbors. The applicants submitted the revised soils, geology and caissons plans to the County Soils and Geology Division and the proposed method of stabilization of the area of construction was approved. Section 8. The Glory Trail and Si's Trail cross the property and will be affected by this project, however they will be restored and improved as part of the mitigation measures in accordance with the requirements of the Rolling Hills Community Association. Resolution No.2010-30 Fozoonmehr 2 ✓ I . • Section 9. In 2008, as part of the mitigation measures, a biological resources study was prepared for the affected properties. The applicants retained a licensed Biological Resources Consultants to study the natural environment in the area to determine the impact, if any the proposed project would have on the natural environment. The consultant's recommendations are incorporated into the conditions of approval of this resolution and mitigation measures accepted by the applicant. Section 10. On July 30, 2008, Planning staff prepared an initial study for the project. The initial study found that the project would not have a significant effect on the environment if certain mitigation measures were included in the project. A Mitigated Negative Declaration was prepared for the project and was circulated to the applicant and other interested parties in accordance with State of California Environmental Quality Act (CEQA). Copies of the Mitigated Negative Declaration were sent to adjacent cities and other governmental agencies. The public notice of the Planning Commission's intent to recommend approval of the Mitigated Negative Declaration was published on July 5, 2008 in the local newspaper. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. Section 11. Section 17.46.030 requires a development plan to be submitted for site plan review and approval before any grading requiring a grading permit or any building or structure may be constructed or any expansion, addition, alteration or repair to existing buildings may be made which involve changes to grading or an increase to the size of the building or structure by at least 1,000 square feet and has the effect of increasing the size of the building by more than twenty-five percent (25%) in any thirty-six (36) month period. With respect to the Site Plan Review application requesting substantial grading to stabilize the land and construction of the new residence, pool and future stable and modification to the 2008 project, the Planning Commission makes the following findings of fact: A. The proposed development is compatible with the General PIan, the Zoning Ordinance and surrounding uses because the proposed structures comply with the General Plan requirement of low profile, low-density residential development with sufficient open space between surrounding structures. The project conforms to Zoning Code setback and lot coverage requirements. The net lot area of the lot is 357,280 square feet, (8.2 acres). The proposed residence (8,990 sq.ft.), garage (2,050 sq.ft.), service yard (96 sq.ft.), swimming pool (820 sq.ft.) and future stable (450 sq.ft.) will have 14,438 square feet of structures, which constitutes 3.6% of the net lot which is within the maximum 20% structural lot coverage requirement. A 6,423 square foot basement is proposed for this development. The structural net lot coverage proposed is 12,952 square feet or 3.6% (previously 13,638 square feet or 3.8%), which includes all the structures and future 450 s.f. stable, (20% permitted); and the total lot coverage proposed including the structures and paved areas is 27,180 sq.ft. or 7.6% (previously 27,296 square feet or 7.6%), (35% permitted). The proposed project is screened from the road so as to reduce the visual impact of the development. Disturbed area for this project will be 114,560 square feet or 32.1%, and with future stable 117,620 square feet or 32.9%. Resolution No.2010-30 Fozoonmehr 3 B. The development plan substantially preserves the natural and undeveloped state of the lot by minimizing building coverage because the new structure will not cause the lot to look overdeveloped. Significant portions of the lot will be left undeveloped so as to maintain open space on the property. The existing trees on the southern portion on the parcel will remain and will screen the residence from the neighbors. The nature, condition, and development of adjacent uses, buildings, and structures and the topography of the lot have been considered, and the construction of the new house, pool and future stable will not adversely affect or be materially detrimental to the adjacent uses, buildings, or structures because the proposed structure will be constructed on a portion of the lot which is least intrusive to surrounding properties, will be screened and landscaped with trees and shrubs, is of sufficient distance from nearby residences so that the proposed structures will not impact the view or privacy of surrounding .neighbors, and will substantially utilize the existing most level area for the building pad for the new construction. C. The proposed development, as conditioned, is harmonious in scale and mass with the site, the natural terrain and surrounding residences. As indicated in Paragraph A, the lot coverage maximum set forth in the Zoning Code will not be exceeded and the proposed project is consistent with the scale of the neighborhood. The stabilization of the slope is necessary to prevent future landslide and shall be implemented in slots (stages), so that the entire affected area is not excavated at the same time. D. The development plan incorporates existing trees and native vegetation to the maximum extent feasible. Specifically, the development plan preserves dense brush and shrubs and supplements it with landscaping that is compatible with and enhances the rural character of the community, including the re-vegetation of the existing native plants to a 4:1 ratio. The project will be conditioned upon compliance with the conditions contained in this Resolution, and 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 trees and shrubs. A re-vegetation and landscaping plan is required as part of this approval. E. The development plan follows natural contours of the site to minimize grading and retain the natural drainage courses. Grading for the residential building pad will require 11,200 cubic yards of cut and 7,940 cubic yards of fill (previously'9,420 cubic yards of cut soil and 9,420 cubic yards of fill). For the landslide remediation and buttress fill (key) construction it is estimated that 121,440 cubic yards of cut and same amount of fill will be necessary. (Previously, grading for stabilization of the entire slide, including the adjacent lots and the building pad, were approved at 150,000 cubic yards of cut and 150,000 c.y. of fill). Upon completion of the project the natural drainage course will be preserved and drainage will continue to the canyons at the east side of the lot, across Appaloosa Lane. As a result of this activity drainage on site will be corrected, thus, preventing further erosion of the slopes. F. The proposed development is sensitive and not detrimental to the convenience and safety of circulation for pedestrians and vehicles because the proposed new driveway will be located to maximize sight distance. With the implementation of Resolution No.2010-30 Fozoonmehr 4 C�r i the mitigation measures, during construction, trucks and equipment will not block Appaloosa Lane and all staging shall be on site. G. With the implementation of the proposed mitigation measures, the project conforms to the requirements of the California Environmental Quality Act. Section 12. Based upon the foregoing findings, the Planning Commission hereby approves the Site Plan Review application for Zoning Case No. 757 MODIFICATION for substantial and remedial grading and for construction of a new residence, pool and future stable as shown on the Development plans dated August 12 and August 21, 2008, and as amended by a plan dated November 5, 2010 subject to the following conditions: A. The Site Plan Review approval shall expire on October 16, 2012, unless construction commences on or prior to that date. This time limit takes into consideration the time extension approved by Resolution No. 2010-24 for Zoning Case No. 757. Pursuant to the Zoning Ordinance, no further extension may be granted. B. It is declared and made a condition of the Site Plan Review approval, that if any conditions thereof are violated, this approval shall be suspended and the privileges granted hereunder 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. C. A project superintendent shall be available on site at all times during regular working hours and prior to start of construction a phone number where he/she can be reached shall be provided to City staff and be available on site. D. All requirements of the Los Angeles County Codes, City's Building and Construction Ordinance, the Zoning Ordinance, and of the zone in which the subject property is located must be complied with unless otherwise set forth in the Permit, or shown otherwise on an approved plan. E. This approval includes 20 caissons, or as maybe required by the L.A. County Soils and Geology Division and no grading or disturbance shall extend onto the adjacent properties, unless mutually agreed on and approved by the City and the Building and Safety and/or Public Works Department. E(1). The property line along the area of grading and caissons installation shall be staked throughout the grading process. Such staking shall be in.place at all times during grading and not be removed or disturbed. F. The working drawings submitted to the County Department of Building and Safety for plan check review must conform to the development plan approved with this application. Prior to submittal of final plans to the Building Department for issuance of grading and/or building permits, the plans for the project shall be submitted to staff for verification that the final plans are in compliance with the plans approved by the Planning Commission and that were approved by the RHCA Architectural Committee. Resolution No.2010-30 Fozoonmehr 5 • ' , • Y G. Grading shall not exceed 11,200 cubic yards of cut and 7,940 cubic yards of fill for the residential building pad. For the landslide remediation and buttress fill (key) construction grading shall be kept to the maximum extent practicable to no more than 121,440 cubic yards of cut and same amount of fill. Grading for the future stable shall not exceed 72 cubic yards of cut and 72 cubic yards of fill for a 1,200-sq.ft pad. Additional grading may be required for a larger stable pad and shall be submitted for approval to the City. H. This approval does not include the construction of a stable and corral. Future construction of a stable and corral shall meet the development standards and process for stables in Section 17.18 of the Zoning Ordinance. I. The remediation shall be conducted in slots to minimize stockpiling of dirt on the lot. Only the dirt from the basement and other excavation activities may be exported. Otherwise, the grading shall be balanced on site. J. Structural net lot coverage shall not exceed 12,952 square feet or 3.6%, which includes all the structures and future 450 s.f. stable; and the total lot coverage including the structures and paved areas shall not exceed 27,180 sq.ft. or 7.6%. K. Disturbed area for this project shall not exceed 114,560 square feet or 32.1%, and with future stable 117,620 square feet or 32.9%, which includes the previously graded area at the north eastern corner of the lot to accommodate slope stabilization on the adjacent lot (5 Sagebrush Lane). L. The residential building pad shall not exceed 38,080 square feet and will . have coverage of 12,004 or 31.5%. Coverage on the 1,200 square foot future stable pad is proposed at 450 square feet or 37.5%. M. The proposed basement shall not exceed 6,423 square feet and shall meet all requirements of the Los Angeles County Building Code and City Zoning Ordinance for basements, including exit door and provision for light and ventilation. N. Prior to final inspection, the disturbed and graded areas shall be landscaped. Landscaping shall include water efficient irrigation, to the maximum extent feasible, that incorporates low gallonage irrigation system, utilizes automatic controllers, incorporates an irrigation design using "hydrozones," considers slope factors and climate conditions and meets the City's Water Efficient Landscaping Ordinance. To the maximum extent practicable, native trees and other native plants shall be utilized. If trees are to be used in the landscaping scheme for this project, they shall be mature when planted and which at full maturity shall not exceed 20 feet in height; shrubs shall be planted so as not to obstruct views of neighboring properties but, to screen the residential structure on site. O. Two copies of the landscaping and irrigation plan for the graded/repaired and revegetated areas as well as for builidng pad areas and a cost estimate for material, labor and irrigation to implement the landscaping plan, shall be submitted for review by the Planning Department and City's landscaping consultant prior to issuance of a grading permit. Fire Department review of the landscaping shall also be required.

A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS IN ZONING CASE 757 MODIFICATION GRANTING MODIFICATIONS TO A PREVIOUSLY APPROVED SITE PLAN REVIEW FOR SUBSTANTIAL GRADING FOR SLOPE STABILIZATION AND CONSTRUCTION OF A SINGLE FAMILY RESIDENCE ON A VACANT PARCEL OF LAND AT 3 APPALOOSA LANE (LOT 246-MS), ROLLING HILLS, CA. (FOZOONMEHR). A MITIGATED NEGATIVE DECLARATION WAS ADOPTED FOR THE PREVIOUSLY APPROVED PROJECT. DATE: DECEMBER 21,2010 REQUEST AND RECOMMENDATION 1. The applicants, Dr. and Mrs. Fozoonmehr, requested modifications to a previously approved Site Plan Review for substantial grading (150,000 cubic yards of cut and 150,000 cubic yards of fill of soil) to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and on two adjacent lots developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive, and grading and construction of a single family residence with garage and basement, swimming pool and a stable on subject property at 3 Appaloosa Lane. The modification entails reducing the limits of grading by 18,000 square feet by not grading on adjacent lots, and instead, to construct 20 caissons along a portion of the westerly property line and to reduce grading quantities by a total of over 17,400 cubic yards. In addition, a drainage terrace with a not to exceed 4.5-foot high wall is planned to be constructed. The applicants also requested that the Planning Commission waive one of the originally imposed conditions of approval, which requires that a third party consultant be hired by the City, at the owners' expense, to oversee the project. -1 - • • 2. A Mitigated Negative Declaration was adopted for the previously approved project. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. 3. It is recommended that the Planning Commission review and adopt Resolution No. 2010-30 granting the modifications. BACKGROUND 4. At the November 16, 2010 public hearing, the Planning Commission directed staff to prepare a resolution of approval, which would reflect the proposed modifications. 5. The attached Resolution (Resolution No. 2010-30) contains the standard findings and facts described in the original project resolution and includes all of the conditions from the originally approved project — (Resolution 2008-15), including the mitigation measures and conditions relative to the modification request. All references to grading on adjacent lots and conditions related thereto were excluded from the language of the resolution. 6. Due to the grading activity that was unintentionally done on subject property by the neighbor, the disturbed area of the lot has increased by 1.4%, for a total disturbance of the lot of 34.3%, which includes future stable, and is incorporated into the amended resolution. 0 • RESOLUTION NO. 2010-30 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS IN ZONING CASE 757 MODIFICATION GRANTING MODIFICATIONS TO A PREVIOUSLY APPROVED SITE PLAN REVIEW FOR SUBSTANTIAL GRADING FOR SLOPE STABILIZATION AND CONSTRUCTION OF A SINGLE FAMILY RESIDENCE ON A VACANT PARCEL OF LAND AT 3 APPALOOSA LANE (LOT 246-MS), ROLLING HILLS, CA. (FOZOONMEHR). A MITIGATED NEGATIVE DECLARATION WAS ADOPTED FOR THE PREVIOUSLY APPROVED PROJECT. THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DOES HEREBY FIND, RESOLVE AND ORDER AS FOLLOWS: Section 1. An application was duly filed by Dr. and Mrs. Shahran Fozoonmehr with respect to real property located at 3 Appaloosa Lane, (Lot 246-MS), Rolling Hills, CA requesting modification to previously approved Site Plan Review consisting of substantial grading (150,000 cubic yards of cut and 150,000 cubic yards of fill of soil) to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and on two adjacent lots developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive, and grading and construction of a single family residence with garage and basement, swimming pool and a stable. The modification entails reducing the limits of grading by 18,000 square feet by not grading on adjacent lots, and instead, to construct 20 caissons along a portion of the westerly property line and to reduce the surficial grading quantities by a total of over 17,400 cubic yards. In addition, a drainage terrace with a not to exceed 4.5-foot high wall is planned to be constructed, as is required by the Los Angeles County Drainage Engineer. The applicants have also requested that the Planning Commission waive one of the originally imposed conditions of approval, which requires that a third party consultant be hired by the City, at the owners' expense, to oversee the project. Section 2. A Mitigated Negative Declaration was adopted for the previously approved project. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. Section 3. The Planning Commission conducted duly noticed public hearings to consider the application on November 16, 2010. The applicants were 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 and the Planning Commission having reviewed, analyzed and studied said proposal. The applicants and their representatives were in attendance at the hearing. • • Section 4. The property is zoned RAS-2 and is 9.20 acres (gross) in size and 8.20 acres net. The lot is currently vacant. Subject lot is irregular in shape. Portion of Appaloosa Lane is located within the property and does not follow the roadway easement line. Geological studies show an ancient landslide underlying the subject lot and two adjacent lots at 17 and 19 Buggy Whip Drive. To date the lot did not experience any visible earth movement. The proposed construction requires grading and slope stabilization to correct the ancient landslide condition on the subject lot and installation of caissons along the common property lines with the adjacent lots (17 and 19 Buggy Whip). No grading is proposed on the adjacent lots. Section 5. The applicant is proposing to excavate the slope failure area/ancient landslide and replace it with a buttress fill keyed through the ancient slope failure mass. A buttress fill is proposed along the easterly side of the property. A buttress is a tightly compacted fill that acts like a retaining wall and is designed to hold the movement. The grading will be done in progressive slots to avoid stockpiling of soil. Sub-drains drain pipes and catch basins will be installed throughout the project to protect the lot from water erosion. A drainage terrace with a 4.5-foot high plantable wall will also be constructed. Section 6. In 2003, the Planning Commission and the City Council approved an application for the same size development, except that the slope remediation portion of the application was smaller in scope and size. During the detailed soils and geology investigation required by the Los Angeles County Public Works Department for the actual grading of the approved project in 2003, it was determined that the previously delineated ancient landslide extended further than originally found. The 2003 approval expired, and in 2008 the Planning Commission approved same application as in 2003, for an 8,990 square foot residence, 2,050 square foot garage, 462 square feet covered porches, 820 square foot swimming pool, 36 square foot barbecue, 1,264 square feet water feature, 672 square foot future stable with corral and a service yard. A 6,423 square foot basement was also approved. The approved construction required grading and slope stabilization to correct landslide condition on the subject lot and on two adjacent lots at 17 and 19 Buggy Whip Drive. Section 7. Since the 2008 approval, one of the adjacent property owners, on whose property grading was required, withdrew their agreement to allow the applicant to enter their property and conduct stabilization. The applicants, in order to pursue approvals for a new residence, were required to revise their plans to meet the building code requirements for lot stabilization in order to develop the lot. The applicants have therefore proposed to construct caissons along the common property line with their neighbors. The applicants submitted the revised soils, geology and caissons plans to the County Soils and Geology Division and the proposed method of stabilization of the area of construction was approved. Section 8. The Glory Trail and Si's Trail cross the property and will be affected by this project, however they will be restored and improved as part of the mitigation measures in accordance with the requirements of the Rolling Hills Community Association. Resolution No.2010-30 Fozoonmehr 2 Q1 • • Section 9. In 2008, as part of the mitigation measures, a biological resources study was prepared for the affected properties. The applicants retained a licensed Biological Resources Consultants to study the natural environment in the area to determine the impact, if any the proposed project would have on the natural environment. The consultant's recommendations are incorporated into the conditions of approval of this resolution and mitigation measures accepted by the applicant. Section 10. On July 30, 2008, Planning staff prepared an initial study for the project. The initial study found that the project would not have a significant effect on the environment if certain mitigation measures were included in the project. A Mitigated Negative Declaration was prepared for the project and was circulated to the applicant and other interested parties in accordance with State of California Environmental Quality Act (CEQA). Copies of the Mitigated Negative Declaration were sent to adjacent cities and other governmental agencies. The public notice of the Planning Commission's intent to recommend approval of the Mitigated Negative Declaration was published on July 5, 2008 in the local newspaper. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. Section 11. Section 17.46.030 requires a development plan to be submitted for site plan review and approval before any grading requiring a grading permit or any building or structure may be constructed or any expansion, addition, alteration or repair to existing buildings may be made which involve changes to grading or an increase to the size of the building or structure by at least 1,000 square feet and has the effect of increasing the size of the building by more than twenty-five percent (25%) in any thirty-six (36) month period. With respect to the Site Plan Review application requesting substantial grading to stabilize the land and construction of the new residence, pool and future stable and modification to the 2008 project, the Planning Commission makes the following findings of fact: A. The proposed development is compatible with the General Plan, the Zoning Ordinance and surrounding uses because the proposed structures comply with the General Plan requirement of low profile, low-density residential development with sufficient open space between surrounding structures. The project conforms to Zoning Code setback and lot coverage requirements. The net lot area of the lot is 357,280 square feet, (8.2 acres). The proposed residence (8,990 sq.ft.), garage (2,050 sq.ft.), service yard (96 sq.ft.), swimming pool (820 sq.ft.) and future stable (450 sq.ft.) will have 14,438 square feet of structures, which constitutes 3.6% of the net lot which is within the maximum 20% structural lot coverage requirement. A 6,423 square foot basement is proposed for this development. The structural net lot coverage proposed is 12,952 square feet or 3.6% (previously 13,638 square feet or 3.8%), which includes all the structures and future 450 s.f. stable, (20% permitted); and the total lot coverage proposed including the structures and paved areas is 27,180 sq.ft. or 7.6% (previously 27,296 square feet or 7.6%), (35% permitted). The proposed project is screened from the road so as to reduce the visual impact of the development. Disturbed area for this project will be 114,560 square feet or 32.1%, and with future stable 117,620 square feet or 32.9%. Resolution No. 2010-30 Fozoonmehr 3 • • c B. The development plan substantially preserves the natural and undeveloped state of the lot by minimizing building coverage because the new structure will not cause the lot to look overdeveloped. Significant portions of the lot will be left undeveloped so as to maintain open space on the property. The existing trees on the southern portion on the parcel will remain and will screen the residence from the • neighbors. The nature, condition, and development of adjacent uses, buildings, and structures and the topography of the lot have been considered, and the construction of the new house, pool and future stable will not adversely affect or be materially detrimental to the adjacent uses, buildings, or structures because the proposed structure will be constructed on a portion of the lot which is least intrusive to surrounding properties, will be screened and landscaped with trees and shrubs, is of sufficient distance from nearby residences so that the proposed structures will not impact the view or privacy of surrounding neighbors, and will substantially utilize the existing most level area for the building pad for the new construction. C. The proposed development, as conditioned, is harmonious in scale and mass with the site, the natural terrain and surrounding residences. As indicated in Paragraph A, the lot coverage maximum set forth in the Zoning Code will not be exceeded and the proposed project is consistent with the scale of the neighborhood. The stabilization of the slope is necessary to prevent future landslide and shall be implemented in slots (stages), so that the entire affected area is not excavated at the same time. D. The development plan incorporates existing trees and native vegetation to the maximum extent feasible. Specifically, the development plan preserves dense brush and shrubs and supplements it with landscaping that is compatible with and enhances the rural character of the community, including the re-vegetation of the existing native plants to a 4:1 ratio. The project will be conditioned upon compliance with the conditions contained in this Resolution, and 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 trees and shrubs. A re-vegetation and landscaping plan is required as part of this approval. E. The development plan follows natural contours of the site to minimize grading and retain the natural drainage courses. Grading for the residential building pad will require 11,200 cubic yards of cut and 7,940 cubic yards of fill (previously 9,420 cubic yards of cut soil and 9,420 cubic yards of fill). For the landslide remediation and buttress fill (key) construction it is estimated that 121,440 cubic yards of cut and same amount of fill will be necessary. (Previously, grading for stabilization of the entire slide, including the adjacent lots and the building pad, were approved at 150,000 cubic yards of cut and 150,000 c.y. of fill). Upon completion of the project the natural drainage course will be preserved and drainage will continue to the canyons at the east side of the lot, across Appaloosa Lane. As a result of this activity drainage on site will be corrected, thus, preventing further erosion of the slopes. F. The proposed development is sensitive and not detrimental to the convenience and safety of circulation for pedestrians and vehicles because the proposed new driveway will be located to maximize sight distance. With the implementation of Resolution No.2010-30 Fozoonmehr 4 • • the mitigation measures, during construction, trucks and equipment will not block Appaloosa Lane and all staging shall be on site. G. With the implementation of the proposed mitigation measures, the project conforms to the requirements of the California Environmental Quality Act. Section 12. Based upon the foregoing findings, the Planning Commission hereby approves the Site Plan Review application for Zoning Case No. 757 MODIFICATION for substantial and remedial grading and for construction of a new residence, pool and future stable as shown on the Development plans dated August 12 and August 21, 2008, and as amended by a plan dated November 5, 2010 subject to the following conditions: A. The Site Plan Review approval shall expire on October 16, 2012, unless construction commences on or prior to that date. This time limit takes into consideration the time extension approved by Resolution No. 2010-24 for Zoning Case No. 757. Pursuant to the Zoning Ordinance, no further extension may be granted. B. It is declared and made a condition of the Site Plan Review approval, that if any conditions thereof are violated, this approval shall be suspended and the privileges granted hereunder 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. C. A project superintendent shall be available on site at all times during regular working hours and prior to start of construction a phone number where he/she can be reached shall be provided to City staff and be available on site. D.

Date: 11-16-10 Agenda Item No: 7A TO: HONORABLE CHAIRPERSON AND MEMBERS OF THE PLANNING COMMISSION FROM: YOLANTA SCHWARTZ,PLANNING DIRECTOR APPLICATION NO. ZONING CASE NO. 757-Modification SITE LOCATION: 3 APPALOOSA LANE (LOT 246-MS) ZONING AND SIZE: RA-S-2, 8.20 ACRES (NET) APPLICANT: DR. AND MRS. FOZOONMEHR REPRESENTATIVE: DOUGLAS McHATTIE, BOLTON ENGINEERING PUBLISHED: NOVEMBER 4,2010 REQUEST AND RECOMMENDATION • 1. The applicants, Dr. and Mrs. Fozoonmehr, request a modification to a previously approved Site Plan Review for substantial grading (150,000 cubic yards of cut and. 150,000 cubic yards of fill of soil) to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and on two adjacent lots developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive, and grading and construction of a single family residence with garage and basement, swimming pool and a stable on subject property at 3 Appaloosa Lane. The modification entails reducing the limits of grading by 18,000 square feet by not grading on adjacent lots, and instead, to construct 20 caissons along a portion of the westerly property line and to reduce grading quantities by a total of over 17,400 cubic yards. In addition, a drainage terrace with a not to exceed 4.5foot high wall is planed to be constructed. The applicants also request that the Planning Commission consider waiving one of the originally imposed conditions of approval, (request is attached), which requires that a third party consultant be hired by the City, at the owners' expense, to oversee the project. 2. A Mitigated Negative Declaration was adopted for the previously approved project. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant -1 - A • • environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. 3. It is recommended that the Planning Commission review the staff report, open the public hearing, take public testimony consider the request and provide direction to staff. BACKGROUND 4. In 2008 the Planning Commission approved a Site Plan Review request to construct an 8,990 square foot residence, 2,050 square foot garage, 462 square feet covered porches, 820 square foot swimming pool, 36 square foot barbecue, 1,264 square feet water feature, 672 square foot future stable with corral and a service yard. A 6,423 square foot basement, 11 feet deep, was also approved. The approved construction required grading and slope stabilization to correct landslide condition on the subject lot and on two adjacent lots at 17 and 19 Buggy Whip Drive. 5. Since the 2008 approval, one of the adjacent property owners, on whose property minor grading was required, withdrew their agreement to allow the applicant to enter their property and conduct stabilization. The applicants, in order to pursue approvals for a new residence, were required to revise their plans to meet the building code requirements for lot stabilization in order to develop the lot. The applicants have therefore proposed to construct caissons along the common property line with their neighbors. The applicants submitted the revised soils, geology and caissons plans to the County and the proposed method of stabilization of the area of construction was approved. The applicants have also submitted a drainage plan to the County, which was reviewed and returned for minor corrections. The plan will need to be re-submitted (with the corrections) to the County drainage engineer. One of the corrections is to provide a drainage terrace along the eastern potion of the lot, which also requires a short wall. The RHCA Architectural Committee approved the residence and construction plans were submitted to the County Building and Safety Department for plan check. 6. The property is zoned RAS-2 and is 9.20 acres (gross) in size and 8.20 acres net, as calculated for development. The lot is currently vacant. Subject lot is irregular in shape with Appaloosa Lane located along the long portion of the lot. 7. Although the property is large, due to the terrain, less than 15% of the property is developable. The areas not proposed for development, and not of need of grading to correct a landslide condition, will remain in current state with mature trees and native and non-native vegetation interspersed throughout this area. Portion of this area will be re-vegetated with native plants, as required as part of the original approval. 8. A new driveway from Appaloosa Lane was approved by the Planning and Traffic Commissions. Access to the stable will be through an access road not to exceed 25% in slope, and will connect to existing trails and to Appaloosa Lane. A new bridle trail will be constructed near Appaloosa Lane to connect to SI'S trail and another one will be constructed along the western portion of the property to connect to the Glory trail. e • 9. Recently, the Planning Commission granted the applicants an extension of time to commence the grading and construction. 10. One of the conditions of the original approval requires as follows: "The applicant shall reimburse the City for the cost of an independent construction consultant who shall be hired by the City to act as a construction relations officer to monitor the construction activity, including resolution of issues related to implementation of mitigation measures for this project and to assure that all of the conditions of this approval are being complied with. The applicant shall reimburse the City for the actual direct costs of the consultant plus 20% of the consultant's costs as administrative overhead". The applicants request that this condition be taken out as they feel the scope of work has diminished where no grading will be done on adjacent lots as well as County's staff oversight of all projects have increased. The applicants' agent also states that the General Contractor would have a job superintendent on site. MUNICIPAL CODE COMPLIANCE 11. Since submitting the grading, drainage, soils and geology reports and plans to the County, minor modifications were made to the plans. Grading for the residential building pad will require 11,200 cubic yards of cut and 7,940 cubic yards of fill (previously 9,420 cubic yards of cut soil and 9,420 cubic yards of fill). For the landslide remediation and buttress fill (key) construction it is estimated that 121,440 cubic yards of cut and same amount of fill will be necessary. (Previously, grading for stabilization of the entire slide, including the adjacent lots and the building pad, were approved at 150,000 cubic yards of cut and 150,000 c.y. of fill). The total grading will be reduced by over 17,400 cubic yards. It is anticipated that no more than 2,990 cubic yards of dirt from the basement would be exported. However, depending on the shrinkage of the dirt, the basement dirt may have to be used on site. The applicant is proposing to excavate the failed slope area and replace it with a buttress fill keyed through the ancient slope failure mass, (re-compact using the same material). A buttress is a tightly compacted fill that acts like a retaining wall and is designed to hold land movement. The grading will be done in slots to avoid excessive stockpiling of soil.. 12. Storm drainage system will be installed consisting of two swales located on the remediated areas and a swale behind the retaining wall of the building pad. The County drainage engineer requires a drainage terrace to be located to the east of the residence. The terrace construction requires a 4.5 high wall. A MSE (Mechanically Stabilized Earth) wall with geogrid is proposed for that location and will be planted. Subdrains and catch basins will be constructed throughout the project. A dissipater is planned to constructed near the north-easterly property line. 13. A wall, varying in height between 6" curb to 5 feet is proposed to be constructed along the residential building pad and along a portion of the driveway, which was previously approved. A Ak IP . 14. With this modification the applicants are now not proposing to construct the water features or stable and corral, that were previously approved, but to set aside an area for a future stable and corral and for calculations purposes show a future 450 square foot stable. The applicants representative shows a minimum of 1,200 square foot stable pad, which would require 72 cubic yards of grading and a maximum 2,560 square foot set aside area, which would require 143 cubic yards of grading. The net lot area of the lot is 357,280. square feet, (8.2 acres). Two building pads are proposed. The residential building pad is proposed to be 38,080 square feet and will have coverage of 12,502 square feet or 32.8% and with allowances the coverage will be 12,004 or 31.5%. Coverage on the 1,200 square foot future stable pad is proposed at 450 square feet or 37.5%, (on a 2,560 square foot pad, the coverage would be 17.6%). Construction of a stable would require a Conditional Use Permit and would therefore be reviewed by the Planning Commission and the neighbors would have the opportunity to comment on the proposal. 15. The structural net lot coverage proposed is 12,952 square feet or 3.6% (previously 13,638 square feet or 3.8%), which includes all the structures and future 450 s.f. stable. (20% permitted); and the total lot coverage proposed including the structures and paved areas is 27,180 sq.ft. or 7.6% (previously 27,296 square feet or 7.6%), (35% permitted). 16. Disturbed area for this project will be 114,560 square feet or 32.1%, and with future stable 117,620 square feet or 32.9%. (Previously the disturbance for this lot was approved at 32.3%). Disturbance includes any remedial grading (temporary disturbance), any graded slopes and building pad areas, and any nongraded area where impervious surfaces will remain or are proposed to be added. 17. The Glory Trail traverses the rear easement on the property and will be affected by the repairs. It is required that the applicants restore the trail to the satisfaction of RHCA. 18. As a condition of approval, the utility lines to the structures will be placed underground; the roof material will meet City's standards and all other City and County requirements for construction will be met. ENVIRONMENTAL MITIGATION MEASURES ENVIRONMENTAL REVIEW 19. Pursuant to the requirements of the California Environmental Quality Act, (CEQA), staff prepared an Initial Environmental Study for the original proposal. The study identified environmental factors, which would be potentially affected by the proposed project. Those impacts included air quality due to substantial grading; biological resources due to habitat modification; geology and soils due to the extensive grading; hydrology due to substantially altering of existing drainage pattern; noise generated during construction; and traffic generated during construction. A Mitigated Negative Declaration was adopted for the previously approved project. The adopted mitigated measures shall be in full force and effect for this modification, as the project modification would not introduce potentially significant environmental impacts that were not previously addressed in the original Mitigated Negative Declaration. i i The mitigation measures together with the conditions of the original approval (Resolution No. 2008-15), which are applicable, will be incorporated into a modified Resolution, should this modification be approved. CONCLUSION 20. This approval is conditioned on the applicant obtaining the appropriate approvals from the County, the CA Department of Fish and Game, Regional Water Quality Control Board, AQMD and other agencies. The applicant requests that the condition requiring him to hire a third party project manager be waived, as there are many agencies that will be overseeing this project and the general contractor will have a superintendent who would be available at all times. 21. Staff deemed the proposed construction of caissons, elimination of the grading on adjacent lots, the proposed wall construction behind the terrace and the request to waive one of the conditions of approval as "major" modifications, and therefore required that the applicant submit this application to the Planning Commission. The remaining modifications, such as reduction in the overall grading quantities, and changes in the disturbance (by 0.6%) and the construction of the drainage terrace (as required by the County engineer) are not considered major modifications and would have been approved administratively. 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. 17.46.050 Required findings. A. The Commission shall be required to make findings in acting to approve, conditionally approve, or deny a site plan review application. B. 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: 1. The project complies with and is consistent with the goals and policies of the general plan and all requirements of the zoning ordinance; 2. The project substantially preserves the natural and undeveloped state of the lot by minimizing building coverage. Lot coverage requirements are regarded as maximums, and the actual amount of lot coverage permitted depends upon the existing buildable area of the lot; 3. The project is harmonious in scale and mass with the site, the natural terrain and surrounding residences; • 4. The project preserves and integrates into the site design, to the greatest extent possible, existing topographic features of the site, including surrounding native vegetation, mature trees, drainage courses and land forms (such as hillsides and knolls); 5. Grading has been designed to follow natural contours of the site and to minimize the amount of grading required to create the building area; 6.

With all of the safeguards that have been put in place since the approval process and there will be a job Superintendent there at all times, it appears unnecessary to have an independent construction consultant on site. The grading operation has shrunk considerably in scope, primarily as the grading is now totally within the property at 3 Appaloosa Lane and not on any neighboring property. The project will be monitored by the State of California, Fish and Game, The Water Control board, and two divisions of Los Angeles County; Soils and Geology and Drainage and Grading, with written reports submitted every two weeks. The City is observing constantly. Based on the foregoing, I believe this to be a very reasonable request. Sincerely, lad.4r4e • Douglas K.

THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DOES HEREBY FIND, RESOLVE AND ORDER AS FOLLOWS: Section 1. An application was duly filed by Dr. and Mrs. Shahran Fozoonmehr with respect to real property Iocated at 3 Appaloosa Lane, (Lot 246-MS), Rolling Hills, CA requesting a Site Plan Review for substantial grading (150,000 cubic yards of cut and 150,000 cubic yards of fill of soil) over an 126,000 square foot area, (2.89 acres), to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and on two adjacent lots, developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive (Lot 246-MS, Lot 6-BW and Lot 247-5-MS), and grading and construction of a 8,990 square foot single family residence, 2,050 square foot garage, 820 square foot swimming pool, service yard, barbecue and a 450 square foot future stable. A 6,423 square foot basement is also proposed. Section 2. The Planning Commission conducted duly noticed public hearings to consider the application on July 15 and August 19, 2008 and at a field trip visit on August 19, 2008. The applicants were 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 and the Planning Commission having reviewed, analyzed and studied said proposal. The applicants and their representatives were in attendance at the hearings. Several neighbors attended the hearings and expressed their opinion and a letter in favor of the project was also submitted. Section 3. The property is zoned RAS-2 and is 9.20 acres (gross) in size and 8.20 acres net. The lot is currently vacant. Subject lot is irregular in shape. Portion of Appaloosa Lane is located within the property and does not follow the roadway easement line. Geological studies show an ancient landslide underlying the subject lot and two adjacent lots at 17 and 19 Buggy Whip Drive. To date the lot did not experience any visible landslide or movement of earth. The proposed construction requires grading and slope stabilization to correct the ancient landslide condition on the subject lots. Section 4. The applicant is proposing to excavate the slope failure area/ancient landslide and replace it with a buttress fill keyed through the ancient slope 111 411 failure mass. A buttress fill is proposed along the easterly side of the property and along the north westerly sides of the lot. A buttress is a tightly compacted fill that acts like a retaining wall and is designed to hold the movement. The grading will be done in progressive slots to avoid stockpiling of soil. Sub-drains, drain pipes and catch basins will be installed throughout the project to protect the lot from water erosion. Section 5. In 2003, the Planning Commission and the City Council approved an application for the same size development, except that the slope remediation portion of the application was smaller in scope and size. During the detailed soils and geology investigation required by the Los Angeles County Public Works Department for the actual grading of the approved project in 2003, it was determined that the previously delineated ancient landslide extended much further than originally found. Therefore, the Los Angeles County Public Works Division would not approve the project without having the applicant remediate the entire slide. The applicant conducted additional investigation and is proposing to remediate the entire slide area, which continues onto adjacent properties, 17 and 19 Buggy Whip Drive. Section 6. The Glory Trail and Si's Trail cross the property and will be affected by this project, however they will be restored and improved as part of the mitigation measures in accordance with the requirements of the Rolling Hills Community Association. Section 7. As part of the mitigation measures, a biological resources study was prepared for the affected properties. The applicants retained a licensed Biological Resources Consultants to study the natural environment in the area to determine the impact, if any, the proposed project would have on the natural environment. The consultant's recommendations are incorporated into the conditions of approval of this resolution and mitigation measures accepted by the applicant. Section 8. On July 30, 2008, Planning staff prepared an initial study for the project. The initial study found that the project would not have a significant effect on the environment if certain mitigation measures were included in the project. A Mitigated Negative Declaration was prepared for the project and was circulated to the applicant and other interested parties in accordance with State of California Environmental Quality Act(CEQA). Copies of the Mitigated Negative Declaration were sent to adjacent cities and other governmental agencies. The public notice of the Planning Commission's intent to recommend approval of the Mitigated Negative Declaration was published on July 5, 2008 in the local newspaper. Section 9. The Planning Commission reviewed the proposed Mitigated Negative Declaration and finds that it represents the independent judgment of the City, that it incorporates comments received from the Air Quality Management District and that it was prepared in compliance with CEQA requirements. Therefore, the Planning • Commission finds that although the proposed project could have an effect on the Resolution No. 2008-15 Fozoonmehr 2 11 • immediate environment, there will not be a significant effect in this case because mitigation measures have been added to the project, and are incorporated herein to reduce the environmental effects to a level of insignificance. Based on these findings, the Planning Commission hereby adopts the Mitigated Negative Declaration and mitigation measures in accordance with the CEQA requirements. Section 10. The Los Angeles County Department of Public Works Land Development Division and Soils and Geology Divisions reviewed the subject application for the slope repair. The Los Angeles County staff found that the proposed approach and methodology for slope repair is appropriate and are working with the applicant to finalize their approval. The applicant's engineer has consulted with other agencies having jurisdiction in this case and is working towards obtaining their permits and certifications No grading or repair work shall be permitted, until the applicant secures all necessary approvals and permits. In addition, no grading or repair work shall be permitted, until the applicant secures agreements with the adjacent property owners to enter their properties for the purpose of remediation of the slope. Section 11. Section 17.46.030 requires a development plan to be submitted for site plan review and approval before any grading requiring a grading permit or any building or structure may be constructed or any expansion, addition, alteration or repair to existing buildings may be made which involve changes to grading or an increase to the size of the building or structure by at least 1,000 square feet and has the effect of increasing the size of the building by more than twenty-five percent (25%) in any thirty-six (36) month period. With respect to the Site Plan Review application requesting substantial grading to stabilize the land and construction of the new residence and stable, the Planning Commission makes the following findings of fact: A. The proposed development is compatible with the General Plan, the Zoning Ordinance and surrounding uses because the proposed structures comply with the General Plan requirement of low profile, low-density residential development with sufficient open space between surrounding structures. The project conforms to Zoning Code setback and lot coverage requirements. The net lot area of the lot is 357,280 square feet, (8.2 acres). The proposed residence (8,990 sq.ft.), garage (2,050 sq.ft.), service yard (96 sq.ft.), swimming pool (820 sq.ft.) and future stable (450 sq.ft.) will have 14,438 square feet of structures, which constitutes 3.6% of the net lot which is within the maximum 20% structural lot coverage requirement. A 6,423 square foot basement is proposed for this development The total lot coverage including all structures, paved areas and driveway will be 25,900 square feet, which constitutes 7.3% of the net lot which is within the 35% maximum overall net lot coverage requirement. The proposed project is screened from the road so as to reduce the visual impact of the development. The disturbed area of the lot will be 32.3%, which is within the 40% maximum permitted, and includes the stable. • Resolution No.2008-15 Fozoonmehr 3 �Z • • The net lot area of 17 Buggy Whip Drive is 70,750 sq.ft., of which 13,680 square feet will be disturbed for slope remediation. The disturbed area of this lot is proposed at 35.9%, which includes the existing and proposed disturbance. The net lot area for 19 Buggy Whip Drive is also 70,750 sq.ft., of which 2,664 square feet will be disturbed for slope remediation. The disturbed area of this lot is proposed at 36.9%, which includes the existing and proposed disturbance. B. The development plan substantially preserves the natural and undeveloped state of the lot by minimizing building coverage because the new structure will not cause the lot to look overdeveloped. Significant portions of the lot will be left undeveloped so as to maintain open space on the property. The existing trees on the southern portion on the parcel will remain and will screen the residence from the neighbors. The nature, condition, and development of adjacent uses, buildings, and structures and the topography of the lot have been considered, and the construction of the new house, pool and future stable will not adversely affect or be materially detrimental to the adjacent uses, buildings, or structures because the proposed structure will be constructed on a portion of the lot which is least intrusive to surrounding properties, will be screened and landscaped with trees and shrubs, is of sufficient distance from nearby residences so that the proposed structure will not impact the view or privacy of surrounding neighbors, and,will substantially utilize the existing most level area for the building pad for the new construction. C. The proposed development, as conditioned, is harmonious in scale and mass with the site, the natural terrain and surrounding residences. As indicated in Paragraph A, the lot coverage maximum set forth in the Zoning Code will not be exceeded and the proposed project is consistent with the scale of the neighborhood. The stabilization of the slope is necessary to prevent future landslide and shall be implemented in slots (stages), so that the entire affected area is not excavated at the same time. D. The development plan incorporates existing trees and native vegetation to the maximum extent feasible. Specifically, the development plan preserves dense brush and shrubs and supplements it with landscaping that is compatible with and enhances the rural character of the community, including the re-vegetation of the existing native • plants to a 4:1 ratio. The project will be conditioned upon compliance with the conditions contained in this Resolution, and 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 trees and shrubs. A re-vegetation and landscaping plan is required as part of this approval. E. The development plan follows natural contours of the site to minimize grading and retain the natural drainage courses. Grading for the construction of the structures will involve 9,420 cubic yards of cut and 9,420 cubic yards of fill and will be balanced on site. Stabilization of the landslide area of 2.89 acres will involve 150,000 cubic yards of cut and 150,000 cubic yards of fill, which will also remain on site and not be exported. Upon completion of the project the natural drainage course will be Resolution No.2008-15 Fozoonmehr (--;-3 4 i • preserved and drainage will continue to the canyons at the east side of the lot, across Appaloosa Lane. As a result of this activity drainage on site will be corrected, thus, preventing further erosion of the slopes. This project will also correct erosion on the adjacent property by installing proper drainage devices. F. The proposed development is sensitive and not detrimental to the convenience and safety of circulation for pedestrians and vehicles because the proposed new driveway will be located to maximize sight distance. With the implementation of the mitigation measures, during construction, trucks and equipment will not block Appaloosa Lane and all staging shall be on site. G. With the implementation of the proposed mitigation measures, the project conforms to the requirements of the California Environmental Quality Act. Section 12. Based upon the foregoing findings, the. Planning Commission hereby approves the Site Plan Review application for Zoning Case No. 757 for substantial and remedial grading and for construction of a new residence, pool and future stable as shown on the Development Plan dated July 9, 2008 and the revised plans dated August 12 and August 21, 2008, subject to the following conditions: A. The Site Plan Review approval shall expire within two years from the effective date of approval if construction pursuant to this approval has not commenced within that time period, as required by Section 17.46.080(A) of the Municipal Code, or the approval granted is otherwise extended pursuant to the requirements of that section. B. It is declared and made a condition of the Site Plan Review approval, that if any conditions thereof are violated, this approval shall be suspended Rolling Hills and the privileges granted hereunder 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. C. The applicant shall reimburse the City for the cost of an independent construction consultant who shall be hired by the City to act as a construction relations officer to monitor the construction activity, including resolution of issues related to implementation of mitigation measures for this project and to assure that all of the conditions of this approval are being complied with. The applicant shall reimburse the City for the actual direct costs of the consultant plus 20% of the consultant's costs as administrative overhead. D. All requirements of the Los Angeles County Codes, City's Building and Construction Ordinance, the Zoning Ordinance, and of the zone in which the subject property is located must be complied with unless otherwise set forth in the Permit, or shown otherwise on an approved plan. • Resolution No.2008-15 Fozoonmehr j 5 �"7 • • E.

THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS DOES HEREBY FIND, RESOLVE AND ORDER AS FOLLOWS: Section 1. An application was duly filed by Dr. and Mrs. Shahran Fozoonmehr with respect to real property located at 3 Appaloosa Lane, (Lot 246-MS), Rolling Hills, CA requesting a Site Plan Review for substantial grading (150,000 cubic yards of cut and 150,000 cubic yards of fill of soil) over an 126,000 square foot area, (2.89 acres), to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and on two adjacent lots, developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive (Lot 246-MS, Lot 6-BW and Lot 247-5-MS), and grading and construction of a 8,990 square foot single family residence, 2,050 square foot garage, 820 square foot swimming pool, service yard, barbecue and a 450 square foot future stable. A 6,423 square foot basement is also proposed. Section 2. The Planning Commission conducted duly noticed public hearings to consider the application on July 15 and August 19, 2008 and at a field trip visit on August 19, 2008. The applicants were 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 and the Planning Commission having reviewed, analyzed and studied said proposal. The applicants and their representatives were in attendance at the hearings. Several neighbors attended the hearings and expressed their opinion and a letter in favor of the project was also submitted. Section 3. The property is zoned RAS-2 and is 9.20 acres (gross) in size and 8.20 acres net. The lot is currently vacant. Subject lot is irregular in shape. Portion of Appaloosa Lane is located within the property and does not follow the roadway easement line. Geological studies show an ancient landslide underlying the subject lot and two adjacent lots at 17 and 19 Buggy Whip Drive. To date the lot did not experience any visible Iandslide or movement of earth. The proposed construction requires grading and slope stabilization to correct the ancient landslide condition on the subject lots. Section 4. The applicant is proposing to excavate the slope failure area/ancient landslide and replace it with a buttress fill keyed through the ancient slope • . y failure mass. A buttress fill is proposed along the easterly side of the property and along the north westerly sides of the lot. A buttress is a tightly compacted fill that acts like a retaining\vall and is designed to hold the movement. The grading will be done in progressive slots to avoid stockpiling of soil. Sub-drains, drain pipes and catch basins will be installed throughout the project to protect the lot from water erosion. • Section 5. In 2003, the Planning Commission and the City Council approved an application for the same size development, except that the slope remediation portion of the application was smaller in scope and size. During the detailed soils and geology investigation required by the Los Angeles County Public Works Department for the actual grading of the approved project in 2003, it was determined that the previously delineated ancient landslide extended much further than originally found. Therefore, the Los Angeles County Public Works Division would not approve the project without having the applicant remediate the entire slide. The applicant conducted additional investigation and is proposing to remediate the entire slide area, which continues onto adjacent properties, 17 and 19 Buggy Whip Drive. Section 6. The Glory Trail and Si's Trail cross the property and will be affected by this project, however they will be restored and improved as part of the mitigation measures in accordance with the requirements of the Rolling Hills Community Association. Section 7. As part of the mitigation measures, a biological resources study was prepared for the affected properties. The applicants retained a licensed Biological Resources Consultants to study the natural environment in the area to determine the impact, if any, the proposed project would have on the natural environment. The consultant's recommendations are incorporated into the conditions of approval of this resolution and mitigation measures accepted by the applicant. Section 8. On July 30, 2008, Planning staff prepared an initial study for the project. The initial study found that the project would not have a significant effect on the environment if certain mitigation measures were included in the project. A Mitigated Negative Declaration was prepared for the project and was circulated to the applicant and other interested parties in accordance with State of California Environmental Quality Act (CEQA). Copies of the Mitigated Negative Declaration were sent to adjacent cities and other governmental agencies. The public notice of the • Planning Commission's intent to recommend approval of the Mitigated Negative Declaration was published on July 5, 2008 in the local newspaper. Section 9. The Planning Commission reviewed the proposed Mitigated Negative Declaration and finds that it represents the independent judgment of the City, that it incorporates comments received from the Air Quality Management District and that it was prepared in compliance with CEQA requirements. Therefore, the Planning Commission finds that although the proposed project could have an effect on the Resolution No.2008-15 Fozoonmehr4110 • 2 • • immediate environment, there will not be a significant effect in this case because mitigation measures have been added to the project, and are incorporated herein to reduce the environmental effects to a level of insignificance. Based on these findings, the Planning Commission hereby adopts the Mitigated Negative Declaration and mitigation measures in accordance with the CEQA requirements. Section 10. The Los Angeles County Department of Public Works Land Development Division and Soils and Geology Divisions reviewed the subject application for the slope repair. The Los Angeles County staff found that the proposed approach and methodology for slope repair is appropriate and are working with the applicant to finalize their approval. The applicant's engineer has consulted with other agencies having jurisdiction in this case and is working towards obtaining their permits and certifications No grading or repair work shall be permitted, until the applicant secures all necessary approvals and permits. In addition, no grading or repair work shall be permitted, until the applicant secures agreements with the adjacent property owners to enter their properties for the purpose of remediation of the slope. Section 11. Section 17.46.030 requires a development plan to be submitted for site plan review and approval before any grading requiring a grading permit or any building or structure may be constructed or any expansion, addition, alteration or repair to existing buildings may be made which involve changes to grading or an increase to the size of the building or structure by at least 1,000 square feet and has the effect of increasing the size of the building by more than twenty-five percent (25O1o) in any thirty-six (36) month period. With respect to the Site Plan Review application requesting substantial grading to stabilize the land and construction of the new residence and stable, the Planning Commission makes the following findings of fact: A. The proposed development is compatible with the General Plan, the Zoning Ordinance and surrounding uses because the proposed structures comply with the General Plan requirement of low profile, low-density residential development with sufficient open space between surrounding structures. The project conforms to Zoning Code setback and lot coverage requirements. The net lot area of the lot is 357,280 square feet, (8.2 acres). The proposed residence (8,990 sq.ft.), garage (2,050 sq.ft.), service yard (96 sq.ft.), swimming pool (820 sq.ft.) and future stable (450 sq.ft.) will have 14,438 square feet of structures, which constitutes 3.6% of the net lot which is within the maximum 20% structural lot coverage requirement. A 6,423 square foot basement is proposed for this development The total lot coverage including all structures, paved areas and driveway will be 25,900 square feet, which constitutes 7.3% of the net lot which is within the 35% maximum overall net lot coverage requirement. The proposed project is screened from the road so as to reduce the visual impact of the development. The disturbed area of the lot will be 32.3%, which is within the 40% maximum permitted, and includes the stable. Resolution No.2008-15 Fozoonmehr 3 • • The net lot area of 17 Buggy Whip Drive is 70,750 sq.ft., of which 13,680 square feet will • be disturbed for slope remediation. The disturbed area of this lot is proposed at 35.9%, which includes the existing and proposed disturbance. The net lot area for 19 Buggy Whip Drive is also 70,750 sq.ft., of which 2,664 square feet will be disturbed for slope remediation. The disturbed area of this lot is proposed at 36.9%, which includes the existing and proposed disturbance. B. The development plan substantially preserves the natural and undeveloped state of the lot by minimizing building coverage because the new structure will not cause the lot to look overdeveloped. Significant portions of the lot will be left undeveloped so as to maintain open space on the properly. The existing trees on the southern portion on the parcel will remain and will screen the residence from the neighbors. The nature, condition, and development of adjacent uses, buildings, and structures and the topography of the lot have been considered, and the construction of the new house, pool and future stable will not adversely affect or be materially detrimental to the adjacent uses, buildings, or structures because the proposed structure will be constructed on a portion of the lot which is least intrusive to surrounding properties, will be screened and landscaped with trees and shrubs, is of sufficient distance from nearby residences so that the proposed structure will not impact the view or privacy of surrounding neighbors, and will substantially utilize the existing most level area for the building pad for the new construction. C. The proposed development, as conditioned, is harmonious in scale and mass with the site, the natural terrain and surrounding residences. As indicated in Paragraph A, the lot coverage maximum set forth in the Zoning Code will not be exceeded and the proposed project is consistent with the scale of the neighborhood. The stabilization of the slope is necessary to prevent future landslide and shall be implemented in slots (stages), so that the entire affected area is not excavated at the same time. D. The development plan incorporates existing trees and native vegetation to the maximum extent feasible. Specifically, the development plan preserves dense brush and shrubs and supplements it with landscaping that is compatible with and enhances the rural character of the community, including the re-vegetation of the existing native plants to a 4:1 ratio. The project will be conditioned upon compliance with the conditions contained in this Resolution, and 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 trees and shrubs. A re-vegetation and landscaping plan is required as part of this approval. E. The development plan follows natural contours of the site to minimize grading and retain the natural drainage courses. Grading for the construction of the structures will involve 9,420 cubic yards of cut and 9,420 cubic yards of fill and will be balanced on site. Stabilization of the landslide area of 2.89 acres will involve 150,000 cubic yards of cut and 150,000 cubic yards of fill, which will also remain on site and not be exported. Upon completion of the project the natural drainage course will be Resolution No.2008-15 Fozoonmehr • • preserved and drainage will continue to the canyons at the east side of the lot, across Appaloosa Lane. As a result of this activity drainage on site will be corrected, thus, preventing further erosion of the slopes. This project will also correct erosion on the adjacent property by installing proper drainage devices. P. The proposed development is sensitive and not detrimental to the convenience and safety of circulation for pedestrians and vehicles because the proposed new driveway lvill be located to maximize sight distance. With the implementation of the mitigation measures, during construction, trucks and equipment will not block Appaloosa Lane and all staging shall be on site. G. With the implementation of the proposed mitigation measures, the project conforms to the requirements of the California Environmental Quality Act. Section 12. Based upon the foregoing findings, the Planning Commission hereby approves the Site Plan Review application for Zoning Case No. 757 for substantial and remedial grading and for construction of a new residence, pool and future stable as shown on the Development Plan dated July 9, 2008 and the revised plans dated August 12 and August 21, 2008, subject to the following conditions: A. The Site Plan Review approval shall expire within two years from the effective date of approval if construction pursuant to this approval has not commenced within that time period, as required by Section 17.46.080(A) of the Municipal Code, or the approval granted is otherwise extended pursuant to the requirements of that section. B. It is declared and made a condition of the Site Plan Review approval, that if any conditions thereof are violated, this approval shall be suspended Rolling Hills and the privileges granted hereunder 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. C. The applicant shall reimburse the City for the cost of an independent construction consultant who shall be hired by the City to act as a construction relations officer to monitor the construction activity, including resolution of issues related to implementation of mitigation measures for this project and to assure that all of the conditions of this approval are being complied with. The applicant shall reimburse the City for the actual direct costs of the consultant plus 20% of the consultant's costs as administrative overhead. D. All requirements of the Los Angeles County Codes, City's Building and Construction Ordinance, the Zoning Ordinance, and of the zone in which the subject property is located must be complied with unless otherwise set forth in the Permit, or shown otherwise on an approved plan.

(Lot 246-MS). Site Plan Review for substantial grading for slope stabilization and grading for a building pad; and construction of a new single-family residence, garage, pool and future stable. BACKGROUND Attached is a request from Dr. and Mrs. Fozonnmehr for a two-year time extension to commence construction of the previously approved project consisting of substantial grading to repair a landslide condition on the subject lot and grading of small areas on two adjacent lots; grading fora building pad and construction of a new single family residence, garage, pool and a future stable in Zoning Case No. 757. The Planning Commission approved this project on September$ 2008 by Resolution No. 2008-15. One of the conditions of approval requires that the project construction commence within two years from the effective date of the resolution, (October 16, 2008). Pursuant to Section 17.46.070 of the Zoning Ordinance, approvals are valid for the time period specified by the Planning Commission, but not to exceed two years from the effective date of a resolution of approval. The Planning Commission may extend the approval for up to maximum two years. The applicant states that after the plans were prepared and submitted to the County for review, the adjacent property owners withdrew their approval to allow the applicant to grade on their properties. The method of the landslide repair had to be re-evaluated and plans revised.The applicants submitted revised -1 - ti , 1 soils, geology and geotechnical plans to the County Soils and Geology Department, which are currently under review. The applicants will return to the Planning Commission with the revised project, under a request for modification. However, meanwhile, they are requesting an extension for the previous approval. RECOMMENDATION It is recommended that the Planning Commission consider the request arid adopt Resolution No. 2010-24 granting two-years extension to commence grading and construction of this project. If granted, the project would expire in October 2012. • -2- • • RESOLUTION NO. 2010-24 RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS.

AND MRS. FOZOONMEHR REPRESENTATIVE: DOUGLAS McHATTIE, BOLTON ENGINEERING PUBLISHED: JULY 5, 2008 REQUEST The applicants, Dr. and Mrs. Fozoonmehr, request a Site Plan Review for substantial grading (150,000 cubic yards of cut and 150,000 cubic yards of fill of soil) over an 126,000 square foot area, (2.89 acres), to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and on two adjacent lots, developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive (Lot 246-MS, Lot 6- BW and Lot 247-5-MS), and grading and construction of a 8,990 sq.ft. single family residence, 2,050 sq.ft. garage, 820 sq.ft. swimming pool, service yard, barbecue and a 450 sq.ft. stable at 3 Appaloosa Lane. A 6,423 sq.ft. basement is also proposed. The residence is proposed to have a height of between 17' and 20' at the highest ridgeline from the finished grade. Several light wells are proposed, ranging in width from 5 to 8 feet. No new construction is proposed at 17 and 19 Buggy Whip Drive. RECOMMENDATION It is recommended that the Planning Commission review the staff report, view the project, take public testimony and provide direction to staff. ZC No.757 1 W ®Printed on Recycled Paper BACKGROUND AND PREVIOUS MEETING 1. The proposed construction requires grading and slope stabilization to correct landslide condition on the subject Iot and on two adjacent lots at 17 and 19 Buggy Whip Drive. To date the lot did not experience any visible landslide or movement of earth. However, the geological studies show an ancient landslide underlying the lots. 2. At a public hearing in July, the Planning Commission expressed concerns with this development, including size of the development, building pad coverage, soils, geology, and environmental impacts such as noise, pollution, effect of grading on the street and on other properties, stability of the lot and method of grading. Since the July meeting the applicants eliminated 1,264 square feet of water feature, reduced the stable from 672 sq.ft. to 450 sq.ft. and provided a larger building pad. The revised building pad area coverage is proposed to be 30.6% (not including covered porch and barbecue — previously 38.5%). The building pad is proposed to be enlarged from 32,580 sq.ft. to 39,208 sq.ft. The proposed grading would still be within the proposed 150,000 cubic yards of cut and fill and 126,000 square feet of disturbed area. 3. In response to the Commissioners' questions and concerns regarding the size of the development, the request to exceed the building pad area and the location of the blue line stream and the native vegetation the applicants' representatives responded as follows: a) Size of development: The proposed size of the structures is similar to that approved in 2003, except that a smaller basement was proposed (4,750 s.f. vs. 6,423 s.f. currently), and a larger stable (1,671 s.f. vs. 450 s.f. currently). The applicant had the plans approved by the City, all of the various departments in the County of LA and RHCA. The applicants stated that they had spend tremendous amount of time, effort and money, including architectural, engineering and plan checking costs to get to this point only to find out that the previous soils/geology reports were faulty and that the County would not approve the landslide repair as proposed in 2003. It would be a financial and time consuming hardship to have to redesign the project and having the structural plans resubmit to the various agencies for review. b) Exceeding the guideline for residential building pad coverage: The 2003 approval was for a 29.5% residential pad coverage on a larger pad. The applicants propose to enlarge the pad (since the July meeting) so that the residential building pad coverage would be 30.6%. The pad could be enlarged further, but it would require additional walls. c) Proximity of grading to the street and would rerouting of the road be possible, if it became necessary: The applicants engineer explained that the area of grading for the key is between 50-65 feet from the roadway easement. The grading for the driveway is proposed adjacent to the roadway easement. It is not unusual to grade for driveway near a roadway easement. It is possible that the work area for the grading would extend beyond the key area, however the "buffer" between the work and the roadway is at a minimum of 50-feet. (Also see LA County response). ZC No.757 • d) The applicant's licensed biologist provided a map of the location of the blue line stream, which is attached. With proper management practices, the blue line stream will not be affected by this project. Approximately 0.39 acres of sensitive/native vegetation will be affected, which is located along the western area of the proposed building pad and on portions of the adjacent properties that will be graded. 4. The Commission also asked several technical questions. Staff forwarded the questions to the Los Angeles County Soils and Geology Division as well as the Air Quality Management District (SCAQMD), as appropriate. The responses are attached. During the discussion at the July meeting a statement was made that when approving a project the Planning Commission must answer and make certain findings for approval of a Site Plan. One of them is "that the proposed project minimizes grading and preserves the natural terrain to the greatest extent possible". Responses to question #1 and #6 from LA County Soils and Geology staff generally answer this question. Generally, in order to repair the landslide condition, grading as proposed would be required. So any size structure proposed to be built on this property would probably require the same amount of work before the County could approve it. 5. As stated at the July meeting, many agencies including several environmental agencies had an opportunity to review the Initial Environmental Study. Only SCAQMD replied and recommended additional mitigation measures. Proposed mitigation measures, including those recommended by the SCAQMD are attached. 6. At the previous meeting, the Commission also requested information on the historical landslide repairs on the adjacent property (5 Sagebrush Lane). City's records indicate as follows: In 1988, grading and building permits were issued for the construction of a residence for Dr. J.W. Greenhut at 5 Sagebrush Lane. The grading was not completed and all of the excavated soil was placed back into the excavated area without compaction tests prior to refilling the cut area. Shortly thereafter, the property was taken over by Del Amo Savings Bank. In June of 1994, Del Amo Savings Bank was granted Site Plan Review approval for investigation to determine whether the underlying strata was sufficiently strong to allow construction and to repair the previously aborted grading at the site. The bank did a limited repair work, after which their consultants determined that the lot was stable for future construction. In January of 1994, the new property owner was granted a Site Plan approval for the construction of a single-family house, garage and a pool. During the winter of 1998, a portion of the fill slope just west of the residence failed, and settlement of the western portion of the structure was observed. This situation was remediated by installation of eight caissons at the top of the slope to underpin the house. In 2001 the property owner noticed damage to the pool and requested permission to reconstruct the pool. It was at that time that their sols/geology consultants determined ZC No.757 0 • v slope failure and that it was enlarging eastward and northward onto the adjacent lot. The County required that both lots be fixed prior to reconstruction of the pool. 7. The property is zoned RAS-2 and is 9.20 acres (gross) in size and 8.20 acres net, as calculated for development. The lot is currently vacant. Subject lot is irregular in shape with Appaloosa Lane located along a portion of the length of the lot. Normally, streets are located along the width of a lot. In addition, portion of Appaloosa Lane lies within the property and does not follow the roadway easement line. 8. Although the property is large, due to the terrain, less than 15% of the property is developable, with grading and remediation. The areas not proposed for development, and not of need of grading to correct a Iandslide condition, will remain in current state with mature trees and native and non-native vegetation interspersed throughout this area. Portion of this area will be re-vegetated with native plants, as recommended in the biological assessment study. The northeastern most portion of this property is adjacent to the property off of Sagebrush Lane, which has undergone slope repairs in the past few years. A portion of the subject lot was graded to augment the grading at 5 and 6 Sagebrush Lane for slope repairs. 9. In 2003, the Planning Commission approved an application for the same size development, except that the slope remediation was lesser in scope and size. Prior to purchasing the property the applicants conducted limited soils and geology studies on the property. The then report stated, in part, that "based on an evaluation of the site conditions and findings of this investigation, it is concluded that the subject property is suitable for the proposed development from a geotechnical engineering viewpoint, provided the following conclusions and recommendations are incorporated into design criteria and project specifications and are implemented during construction." The report then made recommendations and conclusions as to the conditions on the site and for future development. However, during the detailed soils and geology investigation required by the Los Angeles County Public Works Department for the actual grading of the approved project in 2003, it was determined that the previously delineated ancient landslide extended much further than originally found. Therefore, the Los Angeles County would not approve the project without having the applicant remediate the entire slide. The applicant conducted additional investigation and is proposing to remediate the entire slide area, which continues onto adjacent properties, 17 and 19 Buggy Whip. 10. The Los Angeles County Soils, Geology and Grading Divisions preliminarily approved the recently prepared soils and geology report and the proposed grading. The latest correction sheets from the County are attached. 11. The adjacent property owners, whose properties will be affected by this remediation expressed cooperation and consent to this work. However, prior to issuance of any permit it must be demonstrated to the City and the County that such an agreement has been reached. 12. A new 16 foot wide driveway from Appaloosa Lane is proposed with a slope of 14% except that the first 20 feet, which will be 7%. Section 17.16.160 requires that ZC No.757 4 CD ti • • driveways not exceed 12% in slope, unless otherwise approved by the Planning Commission, and the first 20 feet of a driveway must not exceed 7%. A similar driveway approach was previously submitted and approved by the Traffic Commission in September 2003, with conditions that the driveway be moved 10 feet and that the oleander trees across the road be removed to improve the sight distance. The proposed plan shows the relocated driveway as recommended by the Traffic Commission. Access to the stable will be through an access road not to exceed 25% in slope, and will connect to existing trails and to Appaloosa Lane. MUNICIPAL CODE COMPLIANCE 13. Grading for the residential building pad will require 9,420 cubic yards of cut soil and fill. For the smaller pad 8,580 cubic yards was required. However, according to the applicant, the grading will be accomplished within the parameters of the global grading of the lot. A landslide condition exists on the ro er p p ty, which will be stabilized with buttress fill. The amount of grading for stabilization of the entire slide, including the adjacent lots and the building pad, will be 150,000 cubic yards of cut and fill. The applicant is proposing to excavate the failed slope area and replace it with a buttress fill keyed through the ancient slope failure mass, (re-compact using the same material). A buttress is a tightly compacted fill that acts like a retaining wall and is designed to hold the movement. The grading will be done in 50-feet slots to avoid excessive stockpiling of soil. The resulting slopes will be similar in gradient to the existing slopes (other than the building pads). 14. Storm drainage system will be installed consisting of three swales located on the remediated areas, a swale behind the retaining wall of the building pad, and subdrains and catch basins throughout the project. 15. A wall, varying in height between 6" curb to 5 foot, 380 feet long, is proposed to be constructed along the residential building pad. 16. The net lot area of the lot is 357,280 square feet, (8.2 acres). Two building pads are proposed. The residential building pad is proposed to be 39,208 square feet. Building pad coverage on the 39,208 square foot residential building pad is proposed at 12,004 square feet or 30.6%, not including the porches and barbecue. Building pad coverage on the 2,380 square foot stable pad is proposed at 450 square feet or 18.9%. The combined building pad coverage will be 29.9%. 17. The structural net lot coverage proposed is 14,438 square feet or 3.6%, which includes all the structures, except the barbecue, (20% permitted); and the total lot coverage proposed including the structures and paved areas is 25,900 square feet or 7.3%, (35% permitted). 18. Disturbed area for this project will be 112,656 square feet or 31.5%, (40% permitted) of the net lot area. Previously, approximately 3,000 square feet were disturbed for the remediation of the adjacent lots, for a total of disturbed area of 115,656 or 32.3%. Disturbance includes any remedial grading (temporary disturbance), any ZC No.757 5 C9, r • • , graded slopes and building pad areas, and any nongraded area where impervious surfaces will remain or are proposed to be added. The net lot area of 17 Buggy Whip Drive is 70,750 sq.ft., of which 13,680 square feet will be disturbed for slope remediation. The disturbed area of this lot is proposed at 35.9%, which includes the existing and proposed disturbance. The net lot area for 19 Buggy Whip Drive is also 70,750 sq.ft., of which 2,664 square feet will be disturbed for slope remediation. The disturbed area of this lot is proposed at 36.9%, which includes the existing and proposed disturbance. 19. The Glory Trail traverses the rear easement on the property and will be affected by the repairs. It will be required that the applicant restore the trail to the satisfaction of the RHCA. 20. As conditions of approval, if the project is approved, the utility lines to the structures will be placed underground; the roof material will meet City's standards and all other City and County requirements for construction will be met. 21. The Rolling Hills Community Association will review the proposed project at a later date. ENVIRONMENTAL MITIGATION MEASURES ENVIRONMENTAL REVIEW 22. Pursuant to the requirements of the California Environmental uali Act, (CEQA), staff prepared an Initial Environmental Study for the proposed project. The study identifies environmental factors, which would be potentially affected by the proposed project. Those factors that would be impacted include air quality due to substantial grading; biological resources due to habitat modification; geology and soils due to the extensive grading; hydrology due to substantially altering of existing drainage pattern; noise generated during construction; and traffic generated during construction. However, all of these impacts will be temporary in nature and mitigation measures will be included with the project, which will lessen the impacts to level of insignificance. Staff amended the study based on Commissioners' comments at the July meeting. 23. CEQA requires that affected property owners, and local, County and State agencies be given at least 30 days to review the environmental documents prior to it being adopted by the Lead Agency, which is the City. Based on information provided to staff by the applicant and previous research and analysis of the surrounding areas, staff prepared the Initial Environmental Study and submitted it to the appropriate agencies. The agencies were given until August 5, 2008 to respond. Only SCAQMD responded to City's initial study and their responses are incorporated into the mitigation measures. 24. As part of the mitigation measures, staff requested that a biological resources study be conducted for the affected properties. The applicants retained a Licensed ZC No.757 6 • • Biological Resources Consultants to study the natural environment in the area to determine the impact if any, the proposed project will have on the natural environment. Their report is enclosed. Staff prepared a list of mitigated measures, which the applicant agreed to comply with, with the understanding that the Planning Commission, City Council or other local and state agencies may submit comments and require that other conditions be met for this project. 25. The Biological Resources Assessment study was received by the City on July 2, 2008, and is attached. The consultant recommends the following: (see p. 15 and 16 of the report) • the construction to be conducted outside bird breeding season (January 15 through September 15) or special studies/measures to be taken if construction to take place during the breeding season • to account for approximately 0.39 acres of lost native lemonadberry coastal scrub habitat, revegetate on site at a ratio of 4:1, for a total of 1.56 acres • Prepare a revegetation plan to include: Project description Revegetation design Plant material Implementation instructions Maintenance (three-years) Monitoring Success Criteria Reporting to City • Implement erosion control measures to minimize surface runoff and deposition of debris in the blue line stream (also a requirement of the LA County Building Code and Regional Water Quality Control Board) CONCLUSION 26. As stated earlier, any approval by the City will be conditioned on the applicant obtaining the appropriate approvals from the County, the CA Department of Fish and Game, Regional Water Quality Control Board and other agencies. 27. The proposed structures were previously approved. Due to land conditions, the applicant is required to grade and remediate large portion of the lot, as well as adjacent lots. Once remediated, the graded areas will be planted and the slopes will not exceed 2:1 gradient. The resulting slopes will be very similar to the existing slopes, therefore no significant change in natural terrain is expected. 28. The development would not exceed City's development standards and no Variances are required. The residential building pad coverage has been diminished to 30.6% coverage. 29. The proposed development will be the largest as compared to similar properties in the vicinity. However, the lot is much larger than any in the area and the Commission could require that the project be screened. In addition, the same size project was approved in 2003. ZC No.757 7 07.1) 0 • r 30. The Planning Commission must find that the application meets the criteria for granting of a Site Plan Review. Some of the goals and policies of the Land Use Element of the General Plan that would be applicable to this application and should be considered by the Planning Commission include City's desire to "maintain Rolling Hills' distinctive rural residential character". Another goal is for the City "to accommodate development which is compatible with and complements existing land uses". The Land Use Element also calls to "maintain and provide regulations for sufficient setbacks and easements to provide buffers between residential uses" and require that development conform with the City's existing low-profile, ranch style architecture". The residence will be located below existing residences and will not block any views. The lot is large and a small portion will be developed. Once the area is remediated and replanted, it will closely resemble the existing conditions. The Commission could require landscaping to block the residence from view from the road and other properties.

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. 17.46.050 Required findings. A. The Commission shall be required to make findings in acting to approve, conditionally approve, or deny a site plan review application. B. 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: 1. The project complies with and is consistent with the goals and policies of the general plan and all requirements of the zoning ordinance; 2. The project substantially preserves the natural and undeveloped state of the lot by minimizing building coverage. Lot coverage requirements are regarded as maximums, and the actual amount of lot coverage permitted depends upon the existing buildable area of the lot; 3. The project is harmonious in scale and mass with the site, the natural terrain and surrounding residences; 4. The project preserves and integrates into the site design, to the greatest extent possible, existing topographic features of the site, including surrounding native vegetation, mature trees, drainage courses and land forms (such as hillsides and knolls); 5. Grading has been designed to follow natural contours of the site and to minimize the amount of grading required to create the building area; 6. Grading will not modify existing drainage channels nor redirect drainage flow,- unless such flow is redirected into an existing drainage course; 7. The project preserves surrounding native vegetation and mature trees and supplements these elements with drought-tolerant landscaping which is compatible with and enhances the rural character of the community, and landscaping provides a buffer or transition area between private and public areas; 8. The project is sensitive and not detrimental to the convenient and safe movement of pedestrians and vehicles; and 9. The project conforms to the requirements of the California Environmental Quality Act.

ZONING CASE NO. 757 SITE LOCATION: 3 APPALOOSA LANE (LOT 246-MS) 17 BUGGY WHIP DRIVE (LOT-6-BW) 19 BUGGY WHIP DRIVE (LOT 247-5-MS) ZONING AND SIZE: RA-S-2, 8.80 ACRES 1.82 EACH ON BUGGY WHIP APPLICANT: DR. AND MRS. FOZOONMEHR REPRESENTATIVE: DOUGLAS McHATTIE, BOLTON ENGINEERING PUBLISHED: JULY 5, 2008 REQUEST The applicants, Dr. and Mrs. Fozoonmehr, request a Site Plan Review for substantial grading (150,000 cubic yards of cut and 150,000 cubic yards of fill of soil) to achieve slope stabilization on a vacant lot located at 3 Appaloosa Lane and on two adjacent lots, developed with single family residences each, at 17 Buggy Whip Drive and 19 Buggy Whip Drive (Lot 246-MS, Lot 6-BW and Lot 247-5-MS), and grading and construction of a single family residence, swimming pool and a stable at 3 Appaloosa Lane. No new construction is proposed at 17 and 19 Buggy Whip Drive. BACKGROUND 1. The applicants request a Site Plan Review to construct an 8,990 square foot residence, 2,050 square foot garage, 462 square feet covered porches, 820 square foot swimming pool, 36 square foot barbecue, 1,264 square feet water feature, 672 square foot future stable with corral and a service yard. A 4,750 square foot basement, 10 feet deep, is also proposed. The proposed residence will have a height of between 17' and 20' at the highest ridgeline from the finished grade. Several light wells are proposed, ranging in width from 5 to 8 feet. The proposed construction requires grading and slope stabilization to correct landslide condition on the subject lot and on two adjacent lots at 17 and 19 Buggy Whip Drive. To date the lot did not experience a landslide or movement of earth. However, the geological studies show an ancient landslide that could become active with construction. 2. The property is zoned RAS-2 and is 9.20 acres (gross) in size and 8.20 acres net, as calculated for development. The lot is currently vacant. Subject lot is irregular in • ZC No.757 I L./ ®Printed on Recycled Paper • shape with Appaloosa Lane located along a portion of the length of the lot. Normally, streets are located along the width of a lot. In addition, portion of Appaloosa Lane lies within the property and does not follow the roadway easement line. Due to the irregular shape and the unusual location of the street along the lot, the front yard setback is located 50 feet from the roadway easement along the entire length of Appaloosa Lane, which traverses the property. The area just opposite the front yard setback is considered the rear yard and all of the other property lines are considered side yards. 3. Although the property is large, due to the terrain, less than 15% of the property is developable. The areas not proposed for development, and not of need of grading to correct a landslide condition, will remain in current state with mature trees and native and non-native vegetation interspersed throughout this area. Portion of this area will be re-vegetated with native plants, as recommended in the biological study. The northeastern most portion of this property is adjacent to the property off of Sagebrush Lane, which has undergone slope repairs in the past few years. A portion of the subject lot was graded to augment the grading at 5 and 6 Sagebrush Lane for slope repairs. 4. In 2003, the Planning Commission approved an application for the same size development, except that the slope remediation was lesser in scope and size. Prior to purchasing the property the applicants conducted limited soils and geology studies on the property. The then report stated, in part, that " Based on an evaluation of the site conditions and findings of this investigation, it is concluded that the subject property is suitable for the proposed development from a geotechnical engineering viewpoint, provided the following conclusions and recommendations are incorporated into design criteria and project specifications and are implemented during construction." The report then made recommendations and conclusions as to the conditions on the site and for future development. However, during the detailed soils and geology investigation required by the Los Angeles County Public Works Department for the actual grading of the approved project in 2003, it was determined that the previously delineated ancient landslide extended much further than originally found. Therefore, the Los Angeles County would not approve the project without having the applicant remediate the entire slide. The applicant conducted additional investigation and is proposing to remediate the entire slide area, which continues onto adjacent properties, 17 and 19 Buggy Whip. The Los Angeles County Soils, Geology and Grading Divisions preliminarily approved the recently prepared soils and geology report and the proposed grading. The soils and geology reports are on file in the Planning Department. 5. The adjacent property owners, whose properties will be affected by this remediation expressed cooperation and consent to this work. An agreement to that effect will be recorded between the applicant and the property owners on Buggy Whip at a later time, and a copy submitted to the City. 6. A new 16 foot wide driveway from Appaloosa Lane is proposed with a slope of 14% except that the first 20 feet, which will be 7%. Section 17.16.160 requires that driveways not exceed 12% in slope, unless otherwise approved by the Planning ZC No.757 20 f • • Commission, and the first 20 feet of a driveway must not exceed 7%. A similar driveway approach was previously submitted and approved by the Traffic Commission in September 2003, with conditions that the driveway be moved 10 feet and that the oleander trees across the road be removed to improve the sight distance. The proposed plan shows the relocated driveway as recommended by the Traffic Commission. Access to the stable will be through an access road not to exceed 25% in slope, and will connect to existing trails and to Appaloosa Lane. MUNICIPAL CODE COMPLIANCE 7. Grading for the residential building pad will require 8,580 cubic yards of cut soil and 8,580 cubic yards of fill. A landslide condition exists on the property, which will be stabilized with buttress fill. The amount of grading for stabilization of the entire slide, including the adjacent lots and the building pad, will be 150,000 cubic yards of cut and fill. The applicant is proposing to excavate the failed slope area and replace it with a buttress fill keyed through the ancient slope failure mass, (re-compact using the same material). A buttress is a tightly compacted fill that acts like a retaining wall and is designed to hold the movement. The grading will be done in slots to avoid excessive stockpiling of soil. The resulting slopes will be similar to the existing slopes, therefore the general terrain of the property (other than the building pads) will not change. 8. Storm drainage system will be installed consisting of three swales located on the remediated areas, a swale behind the retaining wall of the building pad, and subdrains and catch basins throughout the project. 9. A wall, varying in height between 6" curb to 5 feet is proposed to be constructed along the residential building pad and along a portion of the driveway. 10. The net lot area of the lot is 357,280 square feet, (8.2 acres). Two building pads are proposed. The residential building pad is proposed to be 32,580 square feet. Building pad coverage on the 32,580 square foot residential building pad is proposed at 12,564 square feet or 38.5%. Building pad coverage on the 2,380 square foot stable pad is proposed at 672 square feet or 28.2%. The combined building pad coverage will be 37.8%. 11. The structural net lot coverage proposed is 14,438 square feet or 4.0%, which includes all the structures. Excluding the allowances (800 sq.ft. of detached features) the structural lot coverage is proposed at 13,638 or 3.8%, (20% permitted); and the total lot coverage proposed including the structures and paved areas is 27,296 square feet or 7.6%, (35% permitted). 12. Disturbed area for this project will be 109,656 square feet or 30.7%, (40% permitted) of the net lot area. Previously, approximately 3,000 square feet were disturbed for the remediation of the adjacent lots, for a total of disturbed area of 112,656 or 31.5%. Disturbance includes any remedial grading (temporary disturbance), any graded slopes and building pad areas, and any nongraded area where impervious surfaces will remain or are proposed to be added. ZC No.757 . 3 • • i The net lot area of 17 Buggy Whip Drive is 70,750 sq.ft., of which 13,680 square feet will be disturbed for slope remediation. The disturbed area of this lot is proposed at 35.9%, which includes the existing and proposed disturbance. The net lot area for 19 Buggy Whip Drive is also 70,750 sq.ft., of which 2,664 square feet will be disturbed for slope remediation. The disturbed area of this lot is proposed at 36.9%, which includes the existing and proposed disturbance. 13. The Glory Trail traverses the rear easement on the property and will be affected by the repairs. It will be required that the applicant restore the trail to the satisfaction of the RHCA. 14. As conditions of approval, if the project is approved, the utility lines to the structures will be placed underground; the roof material will meet City's standards and all other City and County requirements for construction will be met. 15. The Rolling Hills Community Association will review the proposed project at a later date. ENVIRONMENTAL MITIGATION MEASURES ENVIRONMENTAL REVIEW 16. Pursuant to the requirements of the California Environmental Quality Act, (CEQA), staff prepared an Initial Environmental Study for the proposed project. The study identifies environmental factors, which would be potentially affected by the proposed project. Those factors that would be impacted include air quality due to substantial grading; biological resources due to habitat modification; geology and soils due to the extensive grading; hydrology due to substantially altering of existing drainage pattern; noise generated during construction; and traffic generated during construction. However, all of these impacts will be temporary and mitigation measures will be included with the project, which will lessen the impacts to level of insignificance. 17. CEQA requires that affected property owners, and local, County and State agencies be given at least 30 days to review the environmental documents prior to it being adopted by the Lead Agency, which is the City. Based on information provided to staff by the applicant and previous research and analysis of the surrounding areas, staff prepared the Initial Environmental Study and submitted it to the appropriate agencies. The agencies were given until August 5, 2008 to respond. 18. As part of the mitigation measures, staff requested that a biological resources study be conducted for the affected properties. The applicants retained a Biological Resources Consultants to study the natural environment in the area to determine the impact if any, the proposed project will have on the natural environment. Their report is enclosed. Staff prepared a list of mitigated measures, which the applicant agreed to comply with, with the understanding that the Planning Commission, City Council or ZC No.757 of • • other local and state agencies may submit comments and require that other conditions be met for this project. The list of mitigated measures prepared by staff is listed in the Environmental Study. 19. The Biological Resources Assessment study was received by the City on July 2, 2008, and is attached. The consultant recommends the following: (see p. 15 and 16 of the report) • the construction to be conducted outside bird breeding season (January 15 through September 15) or special studies/measures to be taken if construction to take place during the breeding season • to account for approximately 0.39 acres of lost native lemonadberry coastal scrub habitat, revegetate on site at a ratio of 4:1, for a total of 1.56 acres • Prepare a revegetation plan to include: Project description Revegetation design Plant material Implementation instructions Maintenance (three-years) Monitoring Success Criteria Reporting to City • Implement erosion control measures to minimize surface runoff and deposition of debris in the blue line stream (also a requirement of the LA County Building Code and Regional Water Quality Control Board) These conditions and the mitigated measures described above, together with all other conditions recommended by other agencies, will be included in a resolution of approval, should this project be approved. CONCLUSION 20. As stated earlier, any approval by the City will be conditioned on the applicant obtaining the appropriate approvals from the County, the CA Department of Fish and Game, Regional Water Quality Control Board and other agencies. 21. The proposed structures were previously approved. Due to land conditions, the applicant is required to grade and remediate large portion of the lot, as well as adjacent lots. Once remediated, the graded areas will be planted and the slopes will not exceed 2:1 gradient. The resulting slopes will be very similar to the existing slopes, therefore no change in natural terrain is expected. 22. The development would not exceed City's development standards and no Variances are required. However, the residential building pad coverage is proposed to exceed the 30% coverage. 23. The proposed development will be the Iargest as compared to similar properties in the vicinity. However, the lot is much larger than any in the area and the ZC No.757 5 � • • Commission could require that the project be screened. In addition, the same size project was approved in 2003. 24.

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. ZC No.757 8 `� ) . S 17.46.050 Required findings. A. The Commission shall be required to make findings in acting to approve, conditionally approve, or deny a site plan review application. B. 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: 1. The project complies with and is consistent with the goals and policies of the general plan and all requirements of the zoning ordinance; 2. The project substantially preserves the natural and undeveloped state of the lot by minimizing building coverage. Lot coverage requirements are regarded as maximums, and the actual amount of lot coverage permitted depends upon the existing buildable area of the lot; 3. The project is harmonious in scale and mass with the site, the natural terrain and surrounding residences; 4. The project preserves and integrates into the site design, to the greatest extent possible, existing topographic features of the site, including surrounding native vegetation, mature trees, drainage courses and land forms (such as hillsides and knolls); 5. Grading has been designed to follow natural contours of the site and to minimize the amount of grading required to create the building area; 6. Grading will not modify existing drainage channels nor redirect drainage flow, unless such flow is redirected into an existing drainage course; 7. The project preserves surrounding native vegetation and mature trees and supplements these elements with drought-tolerant landscaping which is compatible with and enhances the rural character of the community, and landscaping provides a buffer or transition area between private and public areas; 8. The project is sensitive and not detrimental to the convenient and safe movement of pedestrians and vehicles; and 9. The project conforms to the requirements of the California Environmental Quality Act. SOURCE: City of Rolling Hills Zoning Ordinance ZC No.757
