CITY OF SANTA ANA <br />Planning and Building Agency <br />April 16, 2025 Project Plumber 25129-25 <br />Page 12 Approved <br />FOR PERMIT ISSUANCE <br />SPECIFICATIONS FOR PLACEMENT OF COMPACTED FILL <br />Master ID: <br />Excavation Date: <br />Any existing low -density soils and/or saturated soils shall be removed to competent natural soil <br />under the inspection of the Geotechnical Engineering Firm. After the exposed surface has been <br />cleansed of debris and/or vegetation, it shall be scarified until it is uniform in consistency, <br />brought to the proper moisture content and compacted to a minimum of 90% relative <br />compaction (in accordance with ASTM: D 1557). <br />In any area where a transition between fill and native soil or between bedrock and soil are <br />encountered, additional excavation beneath foundations and slabs will be necessary in order to <br />provide uniform support and avoid differential settlement of the structure. <br />Material for Fill <br />The on -site soils or approved import soils may be utilized for the compacted fill provided they <br />are free of any deleterious materials and shall not contain any rocks, brick, asphaltic concrete, <br />concrete or other hard materials greater than eight inches in maximum dimensions. Any import <br />soil must be approved by the Geotechnical Engineering firm a minimum of 72 hours prior to <br />importation of site. <br />Placement of Compacted Fill Soils <br />The approved fill soils shall be placed in layers not in excess of six inches in thickness. Each lift <br />shall be uniform in thickness and thoroughly blended. The fill soils shall be brought to within 2% <br />of the optimum moisture content, unless otherwise specified by the Geotechnical Engineering <br />firm. Each lift shall be compacted to a minimum of 90% relative compaction (in accordance with <br />ASTM: D 1557) and approved prior to the placement of the next layer of soil. Compaction tests <br />shall be obtained at the discretion of the Geotechnical Engineering firm but to a minimum of one <br />test for every 500 cubic yards placed and/or for every 2 feet of compacted fill placed. <br />NorCal Engineering <br />
