MITIGATION MONITORING PLAN <br /> <br /> Impact / Specific Plan Measure Timing <br /> <br />4.1-7: General Plan Consistency - Aggregate Mining and <br /> Residential Uses <br /> <br />Implement the Specific Plan measures identified in Section 4.5, Noise, and Prior to commencement of <br />Section 4.6, Air Quality. mining activities. <br /> <br />EARTH RESOURCES (Section 4.2) <br /> <br />4.2-1: Site Seismicity <br /> <br />All structures and constructed slopes shall be designed in accordance with the Prior to issuance of building <br />most recent adopted Uniform Building Code as modified by the California permit. <br />Code of Regulations. A soils and geotechnical report shall be prepared for each <br />individual development (unless otherwise approved by the City Engineer) <br />within the Specific Plan Area. Analysis presented in the geotechnical report <br />shall conform with the California Division of Mines and Geology <br />recommendations presented in the "Guidelines for Evaluating Seismic Hazards <br />in California." Projects located within the alluvial deposit areas of the project <br />site shall specifically address and be designed to withstand the potential for <br />liquefaction. Projects within the upland areas or adjacent to steep slopes of <br />upland areas shall specifically address the potential for seismically-induced <br />landsliding. The report shall be submitted to the City for review by a qualified <br />consulting geotechnical engineer reporting to the City at the applicant's cost. <br />The project shall incorporate all recommendations of the City's consulting <br />engineer into the project design. <br /> <br />4.2-2: Slope Instability <br /> <br />For areas with slopes steeper than 20% or within or adjacent to existing Prior to issuance of grading <br />landslides, a slope stability analysis report (addressing static and pseudo-static permit. <br />conditions) shall be prepared by a licensed Civil Engineer and include the <br />appropriate recommendations from the approved geotechnical report for any <br />proposed residential development or roadway construction. The report shall <br />provide recommendations for control of surface drainage, adequate <br />groundwater drainage, and slide mass removal or stabilization, if necessary. <br />The analysis shall be supported by investigation of site-specific conditions that <br />shall include, but not be limited to: <br /> <br /> estimated recency of slope failures and potential for continued movement; <br /> <br /> depth of landslides or colluvial deposits and characterization of slide <br /> plane (s); <br /> <br />· shear strength data for subsurface materials at the project site; <br /> <br />· location of springs; <br /> <br />· groundwater level data that characterizes seasonal fluctuations; and <br /> <br />· justification of seismic coefficient used in pseudo-static analysis. <br /> <br />Proposed cut and fill slope designs shall have factors of safety not lower than During grading. <br />1.5 under static conditions and 1.0 under seismic shaking conditions. <br /> <br />Vineyard Avenue Corridor Specific Plan Draft EIR MMP-4 Mitigation Monitoring Plan <br /> <br /> <br />
