repair shall be minimized. All available options sha11 be exp1ored, inc1uding possib1e 10ss of 10ts or the use of more elaborate engineering methods, in order to preserve all existing trees. site drainage shal1 be controlled to minimize landslide instigation or reactivation. All storm drainage except for detention basins, silt ponds, or other special conditions shall be placed in closed conduits. Drainage benches with concrete lined "V" ditches shall be installed at 25' vertical intervals on all cut and fill slopes greater than 30' in vertical height or as otherwise required by the City Engineer. Building setbacks from creek banks, cut slopes, fill slopes, natural slopes, and unstable slopes, and construction of building foundations shall be as specified by the geotechnical engineer and certified engineering geologist. All grading plans and geotechnical reports shall be reviewed by a geotechnical engineering firm retained by the City prior to the commencement of any grading, slope stabilization, or landslide repair on the site. The applicant shall pay the cost of the City's consultant. d. All landslide repair and slope stabilization work shall be done by the applicant before the individual lots are sold. The applicant shall ensure that all recommendations made by the geotechnical engineer and certified engineering geologist are implemented. All earth work, grading, fill placement, slope cutting, and drain installation shall be directly supervised by the geotechnical engineer and certified engineering geologist to verify compliance with recommendations and conditions. stabilization plans may be modified during construction, as recommended by the geotechnical engineer and certified engineering geologist and approved by the city. All landslide repair and slope stabilization grading shall be documented with as-built drawings including an as-built geological map. These maps shall be provided to the City Engineer within 30 Resolution No. PC-91-19 March 13, 1991
