MONITORING VERtF{CATION <br />IDENTIFIED IMPACT RELATED MITIGATION MEASURE implementation Monitoring and Timing Signature Date <br /> Ent' Verification Enti Re uirements <br />prone to liquefaction. These possible published by the California Division of <br />responses to anticipated seismic activity Mines and Geology. <br />represent a pofentfaUy significant impact. <br /> The detaited, design-level geotechnical <br /> investigations should include the following: <br /> • Seismic stability analysis of the <br /> existing on-site soil; " <br /> • Evaluation of liquefaction potential <br /> through the performance of <br /> additional cone penetration tests, <br /> borings, andlor equivalent methods; <br /> and <br /> • Determination of site-specific soil <br /> response characteristics and <br /> maximum credib{e ground <br /> acceleration for an earthquake <br /> recurrence interval specified by the <br /> City. <br /> Recommendations from the investigations, <br /> including appropriate soil stabilization and <br /> foundation construction techniques, <br /> minimum setbacks around potentially <br /> unstable areas, and criteria for the <br /> compaction and treatment of on•site fills, <br /> shall be incorporated into the final project <br /> grading and foundation plans. Irr general, <br /> these recommendations are expected to <br /> include the following requirements: <br /> ^ that aA construction comply with the <br /> most current edition of the Uniform <br /> Building Code for Seismic Zone 4, or <br /> with the most recently adapted <br /> building codes; <br /> ^ that ail project structural designs be <br /> based on proper estimates by the <br /> project geotechnical engineer of <br /> peak and maximum repeatable <br /> earthquake-induced ground surface <br /> acceferatlons expected to occur on <br /> the project site; and <br />~~ <br />Page 94 U:1htyDocumentslDowntnwr?
