4) All landslide repair and slope stabilization <br /> grading shall be documented with as built drawings <br /> including an as-built geological map. These maps <br /> shall be provided to the City Engineer within 30 <br /> days of the completion of grading. <br /> <br /> 5) Landslides in undeveloped areas that are not a <br /> hazard to development shall be left natural and <br /> shall not be repaired. <br /> <br /> e. If the repair and on-going maintenance of landslides, <br /> unstable slopes, drainage systems, siltation ponds, catch <br /> basins, and other geologic hazards are not covered by a <br /> Lighting and Landscape Maintenance district, then the <br /> entire site covered by this development plan shall be <br /> incorporated into a geological hazards abatement <br /> district. <br /> <br />9. Differential Fill <br /> <br /> The applicant shall mitigate the problems of differential fill <br /> settlement as described in the Final EIR. The following <br /> mitigation measures shall be incorporated into the project: <br /> <br /> a. A geotechnical engineer and certified engineering <br /> geologist shall provide detailed recommendations and <br /> plans for site-specific cut and fill slope gradients, <br /> stripping, preparation of sub-grade to receive fill <br /> (including "keying", benching, and construction of <br /> subsurface drains under fill placed on slopes, acceptable <br /> fill material, and fill placement requirements (including <br /> method of placement and degree of fill compaction). <br /> These recommendations and plans shall be incorporated in <br /> the preliminary grading plan as required by the City <br /> Engineer. <br /> <br /> b. Existing fill located north and west of Bernal Avenue not <br /> properly placed or compacted shall be removed and <br /> replaced with engineered fill. However, properly placed <br /> fill that is determined to be adequate to support a <br /> structure with no damaging settlement may remain. <br /> <br /> c. The applicant shall implement the recommendations and <br /> plans addressing differential fill during grading. The <br /> geotechnical engineer and certified engineering geologist <br /> shall provide continuous inspection during grading to <br /> ensure the recommendations and plans are followed. A <br /> compliance report prepared by the geotechnical engineer <br /> and certified engineering geologist shall be submitted to <br /> the City Engineer within 30 days after completion of <br /> grading. <br /> <br /> - 13 - <br /> <br /> <br />
