TABLE 1:VERNALIS WEST AND EAST PROJECT <br /> MITIGATION MONITORING PLAN <br /> Impact Mitigation Measures Monitoring Agency <br /> 4.2 Earth <br /> 4.2-2 Slope Stability. 4.2-2 Unconfined Compressive Strength tests shall be Public Works Department <br /> conducted every 25 vertical feet, or as deemed <br /> necessary by a geotechnical consulting firm, on <br /> block samples obtained for each major slope face <br /> during the excavation of the mining areas to <br /> confirm the strength values used in the <br /> geotechnical analysis. In addition, as the quarry is <br /> excavated, a geotechnical consulting firm shall <br /> inspect the slopes every 25 vertical feet, or as <br /> deemed necessary by the geotechnical consultant, <br /> to evaluate if the observed soils are consistent with <br /> the soil conditions anticipated in the slope stability <br /> analysis and Identify soil conditions at the site that <br /> would decrease the anticipated stability factors of <br /> safety. Proof of compliance with this measure shall <br /> be provided to the San Joaquin County Public <br /> Works Department as part of the annual review <br /> rocess. <br /> 4.2-3 Exposure of 4.2-3(a) The reclaimed slopes shall be compacted to at least County Engineer <br /> people or 90 percent relative compaction and should not be <br /> structures to steeper than 1.5:1,unless otherwise recommended <br /> Injury or damage by a geotechnical consulting firm under contract <br /> from seismic with the County,and the County Engineer. <br /> activity. <br /> 4.2-3(b) The project applicant shall amend the Vernalis Community Development <br /> Central Emergency Response Plan to include Director <br /> Vernalis West and East prior to beginning <br /> excavation of the site, for the review and approval <br /> of the Community Development Director. <br /> 4.3 Biological Resources <br /> San Joaquin County PA-0600028,PA-05008471Teichert Aggregates <br /> Community Development Page 28 <br /> PA-0500847—Conditions of Approval and Monitoring and Mitigation Reporting Plan 11 <br />
