City of Santa Ana <br />7-Eleven Convenience Store and Service Station Project <br />Mitigation Monitoring and Reporting Program <br />Table 1 (cont.): 7-Eleven Convenience Store and Service Station Project Mitigation Monitoring and Reporting Program <br />Mitigation Measures <br />depth of 8 inches, and moisture conditioned to within 0 to 4 <br />percentage points above the optimum moisture content. <br />Hardscape subgrade shall be compacted to at least 90 <br />percent relative compaction. Pavement subgrade shall be <br />compacted to at least 95 percent relative compaction. <br />Field Observation: The Geotechnical Engineer shall check the <br />bottom of excavations. If soft, loose, wet, or otherwise <br />unsuitable soils are encountered, the depth of removal may be <br />extended, or additional recommendations can be provided. <br />Fill Placement and Compaction: Excavated materials <br />determined by the Geotechnical Engineer to be satisfactory <br />can be reused as compacted fill. With the exception of the <br />asphalt and concrete, it is anticipated that the majority of <br />the excavated materials can be re -used as compacted fill <br />soils. The asphalt grinding's may be reused in non -building <br />areas provided they are broken down to less 3 inches and <br />thoroughly mixed with other materials. The existing concrete <br />pavement on the site may be reused within the compacted <br />fill provided all debris such as rebar is removed and the <br />concrete is broken down or crushed to a maximum 3-inch <br />size. The concrete pieces shall be thoroughly mixed with <br />finer soil such that nesting of coarse fragments which could <br />result in voids does not occur. The Geotechnical Engineer <br />shall approve the fill material before placement. <br />Fill shall be placed in 6- to 8-inch thick loose, horizontal lifts, <br />moisture conditioned to within 0 to 4 percentage points <br />above the optimum moisture content, and compacted to at <br />least 95 percent relative compaction. The maximum dry <br />density and optimum moisture content for the evaluation of <br />relative compaction shall be determined in accordance with <br />ASTM D1557. <br />FirstCarbon Solutions <br />Y:\Publications\Client(PN-1N)\0327\03270041\MMRP\03270041 City of Santa Ana 7-Eleven MMRP.docx <br />Verification of Completion <br />Responsible for <br />Method of Verification Timing of Verification Verification Date Initial <br />1-18 <br />
