<br />. <br /> <br />. <br /> <br />. <br /> <br />According to the project geotechnical report, the earth <br />materials on the project site consist mostly of a thin layer of <br />fill soils overlying native silty sands. The fill soils consist <br />of silty sands that are dry to moist, medium dense to very dense <br />and beige. The maximum depth of fill encountered was 0.5 feet. <br />The native soils also consist of silty fine sands to silty <br />coarse sands that are moist to saturated, medium dense to very <br />dense and beige to gray. The project geotechnical report <br />concluded that construction of the proposed project would be <br />geotechnically feasible with design recommendations incorporated <br />into the project. <br /> <br />Mitigations Measures <br /> <br />The following geotechnical recommendations shall be incorporated <br />into plans and specifications. <br /> <br />. <br /> <br />Foundations for two-story dwellings shall be supported <br />entirely by a homogenous layer of certified compacted <br />fill not less than five feet in thickness and extending <br />three feet beyond the perimeter of the proposed building <br />footprint. <br /> <br />. <br /> <br />The project shall comply with the bearing capacity, <br />lateral design, concrete slap on-grade, asphalt concrete <br />and seismic coefficient design recommendations provided <br />in the geotechncial report prepared for the project by <br />Nunewz Engineering, in May 2002. <br /> <br />. <br /> <br />Prior to grading, existing vegetation, trash, surface <br />structures and debris shall be removed-and disposed off- <br />site at a legal dumpsite. Any existing utility lines, or <br />other subsurface structures, which are not to be utilized <br />should be removed, destroyed, or abandoned in compliance <br />with current governmental regulations. <br /> <br />. <br /> <br />Excavated soil may be used as fill and backfill provided <br />that it is clean and free of debris. All areas where <br />certified compacted fill is to be placed shall first be <br />cleaned of structures, concrete, asphalt concrete, <br />vegetation and debris materials. The excavated bottoms of <br />all fill soil excavations shall be observed and approved by <br />the Soil Engineer and the City Building Inspector before <br />backfill with certified compacted fill begins. The soils to <br />be used for compaction should be mixed and watered to <br />obtain uniform optimum moisture content. The soils shall be <br />placed in a layer not thicker than 8 inches and <br /> <br />12 <br /> <br />!~A>!35 <br />
