Section 1 : An application was filed by watt Palos Verdes , Inc . for approval of a tentative tract map to create 64 single- family residential lots and 7 open space parcels on a 63 .85 acre site located along the 6500 block of Palos Verdes Drive South, which is zoned Residential Single Family (RS-1 and RS-2 ) and Open Space Hazard ("OH" ) , and a conditional use permit and grading permit to allow development of a Residential Planned Development ( "RPD" ) consisting of 64 detached single-family homes. Section 2 : Public Hearings were duly held by the Planning Commission on June 14, July 26 , August 9, August 23 , and September 27 , 1988 . On October 27 , 1988 , the Planning Commission reviewed and considered Environmental Impact Report ("EIR" ) No . 28 prepared in connection with the application, certified that it was adequate and completed in compliance with the California Environmental Quality Act ("CEQA" ) in regard to Grading Application NO. 1061 and Conditional Use Permit ("CUP") No . 130 , recommended certification of the EIR with regard to Tentative Tract Map No . 45667 and adopted environmental findings , including a statement of overriding consideration, as set forth .in Planning .Commission Resolutions No. 88-55 and 88-56. Section 3 ; The Planning Commission's approval of the Grading Application No. 1061 and CUP No . 130 was appealed to the City Council and public hearings were duly held by the City Council on the appeal , Tentative Tract Map No . 45667 and EIR No . 28 on November 1 , November 15 and December 15 , 1988 , and January 10 , January 17 , January 31 , March 7 , April 10 , and April 18 , 1989. On May 2 , 1989 , the City Council affirmed the Planning Commission decision that EIR No . 28 is adequate and completed in compliance with CEQA in regard to CUP No . 130 and Grading No. 1061 and certified that it is adequate and completed in compliance with CEQA in regard to Tentative Tract Map No. 45667 , The City Council reviewed and considered EIR No . 28 , prior to acting on the appeal of CUP No . 130 and Grading Application No . 1061 and prior to acting on the application for Tentative Tract Map No . 45667 , and made the following environmental f indings A. The EIR identifies as a potential significant environmental impact the effect of grading in areas of steep slopes . Changes or alterations have been required in, or incorporated into , the project which avoid or lessen this impact . The number of housing units has been reduced from 64 to 43 and the location of the housing units and streets has been altered so that grading will not occur on steep slopes and the final plans will be reviewed for compliance with the conditions of approval contained in CUP No . 130 and Grading Permit No . 1061 . It is not possible to entirely eliminate this impact . B. The EIR identifies as a potential significant impact the alteration of the central drainage ravine as a result of filling the ravine . Changes or alterations have been required in, or incorporated into, the project which lessen or eliminate this impact , The number of housing units has been decreased and the location of the houses and streets has been altered so that it is not necessary to fill the ravine . C . The EIR identifies as a potential significant environmental impact a conflict with the City ' s Trails Network Plan. Changes or alterations have been required in, or incorporated into , the project which lessen or avoid this impact . The dedication of trails through portions of lots 48 , 49 , 51 , 52 , 53 and 54 has been required and further engineering analysis is required prior to construction of any trail . D. The EIR identifies as a potential significant impact the noise from construction activities . Changes have been required in, or incorporated into , the project which avoid or lessen this impact . Construction activities will be limited to the hours of 7 ,*.00 a.m. to 7 .900 p .m. on weekdays and 7 :00 a.m. to 5 :00 p.m. on Saturdays and mufflers and noise baffles are required. It is impossible to entirely eliminate this impact , Eo The EIR identifies as a potential significant environmental impact the truck traffic required to export excavated material during construction. Changes or alterations have been required in, or incorporated ed into, the project which avoid or lessen this impact . The reduction in the number of housing units and the relocation of the housing units and streets has reduced the amount of material to be exported from 485 ,000 cubic yards to 250 ,000 cubic yards , truck traffic exporting dirt will be limited to the hours of 7 .-00 a.m. to 7 :00 p .m. on weekdays and 7 :00 a.m. to 5 :00 p .m. Saturdays , and the haul route used must be approved by the City. It is not possible to entirely eliminate this impact , FO The EIR identifies as a potential significant environmental impact the effect of construction on fossiliferous materials . Changes or alterations have been required in, or incorporated into , the project which lessen or avoid this impact . A fully qualified paleontologist will monitor all rough gradinr, on the site and recover any and all fossils produced from the site . Resolution No. 89-39 Page 2 G. In addition to the mitigation set forth above , the mitigation measures set forth in Exhibit A hereto have been required in, or incorporated into the project . These measures will further reduce those impacts identified in the EIR but not found to be significant , Exhibit A further sets forth the mitigation measures described above in greater detail , H. The City shall monitor the project for compliance with the above mitigation measures , I . The social , economic and other benefits of the project outweigh any unavoidable adverse impacts that may occur. The project will provide needed housing in conformity with the general plan and zoning ordinance , This Resolution implements all feasible mitigation measures identified in the EIR and record of the proceedings . The proejct alternatives identified in the EIR either would not achieve the objective of the project - or would do so only with unacceptable adverse impacts . Accordingly, and for the reasons set forth herein, none of the alternatives are feasible . Both the no-project and public park alternatives (Nos. 1 & 7 ) are environmentally superior but would not provide housing, Alternatives Nos . 2 , 5 and 6 would reduce the number - of housing units from the 64 units proposed and would therefore reduce grading, construction impacts and the amount of dirt to be exported, but not to the extent of the 43-unit project approved by this Resolution. Further, Alternatives 2 and 5 would still require some filling of the central ravine and Alternative 6 would be an unattractive row development with steep access roads . Alternative No . 4 would reduce the amount of common open space provided by the project approved by this Resolution and would not reduce the grading required. An alternative site was not considered feasible as few vacant sites suitable for residential uses remain in the City, and the few remaining parcels suitable for such development are already being evaluated for alternate developments and therefore are not available as alternate locations for this development . Due to the overriding benefits and considerations, the City Council affirms that any unavoidable adverse impacts of the project are acceptable . This paragraph constitutes a statement of overriding considerations pursuant to the California Environmental Quality Act . Resolution No . 89-39 Page 3 PASSED, APPROVED and ADOPTED on May 2 , 1989 .

EARTH 1 '6 The consultants (American Geotechnical ) will review and approve the final plans and specifications by manual signature , 2 * All of the recommendations of the consultants (American Geotechnical ) , except as modified by Robert Stone and Associates , Inc . therein, will be incorporated into the design and construction, 3 * An as-graded soils and geologic report , complete with geologic map , will be submitted and reviewed by the City prior to issuance of a building permit , 4* Foundations and flour slabs caston expansive soils will be designed in accordance with Los Angeles County Code Section 2907-i. Foundations.!,will be -set back from, descending ' slopes in accordance with the code and will extend to such a depth as to beiunaffected by- any creep prone - surficial soil and/or weathered bedrock. Field review by the consultants (American Geotechnical ) is required. 69 The proposed grading will comply with the grading code requirements relative to surface drainage control , i.e . , terrace drains , browditch drains, down-drains, building and drainage , storm drains , etc . and subdrains under all canyon fills , if constructed. Backdrains will be provided at the rear .of all retaining walls where proposed. 7 . All cut and fill slopes will be planted, " The developer will use fire retardant orldrought ,.resistant -type landscaping to minimize landscape watering of the slopes. A landscape plan will be prepared and submitted to the City for approval by an expert in that technical area, EXHIBIT "A" Resolution No. 89-39., Page 1 8 . All grading plans will be reviewed and approved by the developer' s geotechnical consultant , and approved plans will be stamped and signed with a wet signature by the site consultants indicating the approval . 9 . All building and construction areas will be evaluated by the site geotechnical consultant relative to expansive soils and the potential effects and remedial design for all structures including street improvements at the rough grade stage and prior to issuance of building permits . B. HYDROLOGY 1 . Paved drainage ditches shall be used in lieu of yard drains whenever possible to eliminate potential clogging and maintenance problems. open paved ditches shall be placed in a storm drain easement and maintained by the Project 's Homeowner 's Association, 2 . The proposed storm drain improvements shall also be analyzed during the final engineering phase for the adequacy of easements for access . to the storm drain system including inlets , and for possible provisions for potential debris production by either construction of debris basins or other facilities to eliminate debris . 3 . Provision shall be made for debris basins and/or other acceptable facilities for the inlets for the major drainage areas to the tract . 4. Construct a top of slope ditch for the blended slopes above Lots 7 through 12 ( lot 12 deleted) and above Lots 21 through 31 ; and, construct slough walls and ditches ("J" walls ) at the rear of said lots for protection from mudf lows or small surface slope failures on the ungraded areas as directed by the City Engineer, 5 . Redesign yard drains to paved drainage ditches for the lower level lots as directed by the City Engineer. b . The upstream drainage inlets will be designed to use 50 year storm intensities . 7 . Erosion control plans will be required prior to grading and shall be provided and maintained until the subdivision has been sufficiently completed so as to not cause mudf low problems to the downstream roads , storm drain systems and properties. 8 . The City will require 50 year design standards for natural water courses or sump conditions . EXHIBIT "A" Resolution No. 89-39 Page 2 90 The downstream drainage capacities shall be identified by the project engineer and verified by L.A. County Flood Control with all storm control devices designed to LACFC standards and relinquished to same , C . PLANT AND ANIMAL LIFE lo To the extent that it is feasible during grading and construction activities, as much of the coastal sage scrub plant community shall be maintained as is possible. Temporary fencing shall be erected around scrub areas immediately adjacent to grading and construction zones to prevent equipment and vehicles from straying into these areas . 2 . Portions of the coastal sage scrub plant community that are damaged temporarily during grading and construction shall be rehabilitated. Also , after the project is completed, portions of the project site that support weedy vegetation shall be restored with flora of the coastal sage scrub plant community. The final landscape plan shall also permit revegetation of portions of the project site with native coastal sage scrub plants . Existing native plant materials should be used to obtain seeds , cuttings , and pads (specifically for the cacti) , which will be used. to revegetate and propagate plant material for other portions of the project site . 3 * The project shall comply with local fire regulations that may require annual disking of certain portions of the project site , although this activity actually promotes the growth of the weeds and annual vegetation, 4* The final landscape plan shall use fire-retardant , drought tolerant , native plants in 'areas transitional between the completed residential community and scrub habitat zones . A combination of traditional fire breaks along with outplantings of fire tolerant native vegetation shall be incorporated into the development plan, thereby minimizing the need to disk annually extensive portions of the parcel . Do TRAILS 1 * The proposed off-street multi-purpose trails through the open space lots shall be designed and constructed in conformance with the Trail Standards Study, Two alternatives to compensate for the overly steep Hawthorne/Vallon to Palos Verdes Drive South trail alignment should be considered. EXHIBIT "A" Resolution No . 89-39 Page 3 0 Construction of stairways to span the steeper portions of the trail ; or, 0 Construction of .a longer trail to reduce its overall grade to 5%, in conformance with the Trail Standards Study (the trail should be increased by 2 ,925 feet to a total length of 4,800 feet ) . As an option to the City's overall trail grade of 5%, a trail utilizing 5% ( leisure walking grades) with 106 (climbing grades) should be investigated , 2 * All trails shall be constructed with appropriate trail engineering techniques to avoid soil erosion, excessive compaction, and degradation. 3 * Final trail alignment shall be designed to avoid as much of the prickly pear cactus (Opuntia littoralis) as possible , E.
