TABLE 1. MITIGATION MONITORING AND REPORTING PROGRAM <br /> Mitigation Measures Implementation Monitoring Monitoring and Monitoring Verification of <br /> Procedures Responsibility Reporting Action Schedule Compliance <br /> dimensions, placement,and design shall be determined <br /> in the detailed project plans. <br /> Mitigation Measure 4.4-3c:The final corrective grading <br /> plans shall show detailed locations of keyways, <br /> subdrains,debris benches,and subexcavation areas. <br /> The sequence of grading issues,such as placement of <br /> various cut materials in specific locations, should also be <br /> evaluated during review of the final 40-scale grading <br /> plans. <br /> Mitigation Measure 4.4-3d:The Geotechnical Engineer <br /> or qualified representative should be present during all <br /> phases of grading operations to observe demolition,site <br /> preparation,grading operations,and subdrain <br /> placement.After grading operations commence,geologic <br /> observations of cut areas should be made at frequent <br /> intervals so that revised geologic recommendations can <br /> be incorporated into updated grading plans as grading <br /> proceeds. During slope grading, all cut slopes should be <br /> viewed by the Engineering Geologist for adverse <br /> bedding,seepage,or bedrock conditions that may affect <br /> slope stability. In the event that adverse conditions are <br /> identified,overexcavation and reconstruction of the <br /> slopes may be required.Track rolling to compact slope <br /> faces is not sufficient.All fill slopes should be overbuilt at <br /> least two feet and cut back to design grades. <br /> Mitigation Measure 4.4-3e: Keyways equipped with a <br /> subsurface drainage system shall be constructed. Each <br /> keyway shall be keyed into firm natural materials <br /> unaffected by shrinkage cracks.The keyway shall be <br /> filled with materials derived from the Livermore Gravels <br /> compacted to 95 percent relative compaction for non- <br /> expansive materials and 90 percent relative compaction <br /> for expansive materials.The required depth of the <br /> keyways shall be determined in the field by the <br /> geotechnical engineer during grading. Fill above the <br /> keyways shall be benched into firm,competent soil or <br /> bedrock and drained as appropriate. Unless otherwise <br /> recommended by the Geotechnical Engineer, benches <br /> shall be constructed at vertical intervals of not less than <br /> five feet. <br /> LuND RANCH II-PUD-25 10 JANUARY 2016 <br />
