�•���'" <br /> � recyclables shali be provided for each residential tower unit. The City shall that Project <br /> construction inciude these provisions prior to issuance of cert�cates of occupancy <br /> (Mitigation 10-9). <br /> Findings: The mitigation measure idt�tified aiwve is feasible and <br /> reduces the potentially significant environmental impact d�scribed 4bove to a less-than- <br /> significant IeveL - <br /> VIII. SOILS AND GEOLOGY <br /> A. Gradinq. Dredqina and Surface Modifications <br /> Potential Impact: Project grading, dredging and surface mod�cation, ff <br /> not performed appropriately, could cause surface settlement, soil erosion and <br /> unnecessary seismic hazards (Impact 11-1). <br /> Mitigation: The Project will obtain from one or more registered <br /> engineering geologists or geotechnical engineers detailed, design-level <br /> geotechnical investigations to gui�e the design of all Project grading, dredging <br /> and soil stabilization, on a structure-specific basis, and shall provide funds for the <br /> City Engineer to retain an independent engineering geologist or geotechnical <br /> engineer to review and approve the those investigations. All relevant provisions <br /> �;: �, of the approved investigations shall be incorporated into Project plans, and al) <br /> ._ earthwork shall be performed under the direct supervision of a registered <br /> engineering geologist or geotechnical engineer (Mitigation 11-1). <br /> Findings: The mitigation measure identified above is feasible and <br /> reduces the potentially significant environmentat impact described above to a less-than- <br /> significant level. <br /> B. Settlement <br /> Potential Impact: If conventional shallow foundations are used, weak, <br /> compressible Bay mud underlying on-site fill would not adequately support Project <br /> structural loads, causing excessive total and differential settlement (Impact 11-2). <br /> Mitigation: The design-level investigations required by Mitigation 11-1 <br /> shall include laboratory analyses of all material proposed for use as fill meeting the <br /> standards specified in Mitigation 11-2. Fill design shall incorporate the results of these <br /> analyses to minimize the destructive effects of settlement, and all improvements placed <br /> on fill shall aiso be designed in accordance with the design-level investigations required <br /> by Mitigation 11-1 (as further specified and enforced in recommendations in accordance <br /> with Mitigation 11-2). After a final grading plan has been prepared, estimates of <br /> potential settiement shall be prepared for structures and downdrag loads. After fills are <br /> completed, settlement shall be monitored and improvement plans modified as <br /> necessary. Dredged material analysis results shall be included in any appiication or <br /> request for disposal or reuse of dredged material. <br /> i289�o2�ns2�s.z 30 . <br /> Atty/ResWReso.1470 <br /> 052004 <br />
