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 /> periods and <br /> Mitigation Measure 4.4-3b: Debris catchment measures continuously <br /> shall be constructed along Lots 5 and 25 which are maintained. <br /> located at the mouths of existing drainage courses The <br /> catchment measures shall include a minimum 5-foot <br /> berm placed across the mouth of the drainage with clog- <br /> resistant surface drainage inlets provided.The final <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 /> LUND RANCII II-PUD-25 1 0 JANUARY 2016 <br />
