<br />f. A stability analysis to assess the stability of proposed <br />fi11 areas and s10pes sha11 be conducted. The ana1ysis <br />shall use laboratory test results from samples of <br />material to be used as fill. Areas of potential <br />instability shall be identified and recommendations made <br />for stabilization. <br /> <br />g. The entire site shall be incorporated into a geologic <br />hazards abatement district for the repair and on-going <br />maintenance of landslides, unstable slopes, drainage <br />systems, catch basins, siltation ponds, and other <br />geologic hazards. <br /> <br />h. All recommendations of the geotechnical engineer and <br />certified engineering geologist shall be incorporated <br />into the grading plan. <br /> <br />i. Proper building setbacks from creeks and unstable slopes <br />and construction of building foundations and cut and fill <br />slopes shall be as specified by the geotechnical engineer <br />and certified engineering geologist. The landslides for <br />which building setbacks will be determined shall be <br />analyzed under static and dynamic conditions. The <br />results of the stability analyses should include: a) <br />cross sections showing the geometry of the subsurface <br />units or discontinuities, the assumed water table, the <br />search limits (if applicable) and the most critical <br />failure surface(s)j b) the assumed strength parameters <br />for each units as well as the supporting laboratory test <br />data (including normal pressures and strain rates); and <br />c) the method of analysis. Back analysis of existing <br />failures to calibrate strength parameters shall be <br />conducted. <br /> <br />k. All earth work, grading, fill placement, slope cutting, <br />and drain installation shall be directly supervised by <br />the geotechnical engineer and certified engineering <br />geologist to verify compliance with recommendations and <br />conditions. <br /> <br />I. All plans and geotechnical reports shall be reviewed by <br />a geotechnical engineering firm retained by the City <br />prior to the commencement of any grading or slide repair <br />on the site. The applicant shall pay the cost of the <br />city's consultant. All recommendations of the City's <br />consultant shall be incorporated into the project, <br />including those recommendations on the preliminary <br />geologic review by william Cotton and Associates, dated <br />November 30, 1990. <br /> <br />Resolution No. PC-91-9 <br />February 27, 1991 <br />
