M m <br /> D Table 2-2 <br /> Summary of Impacts and Mitigation Measures <br /> C„ Significance Significance <br /> 3 Impacts Before Mitigation Measures After <br /> v <br /> Mitigation Mitigation <br /> measures are deemed insufficient,the geotechnical engineer <br /> shall prepare supplemental site-specific geotechnical report(s) <br /> with appropriate recommendations sufficient to ensure the safety <br /> of project structures and site occupants.These measures could <br /> include,but are not limited to,the construction of deep <br /> foundations,installation of driven piles,and extra reinforcement <br /> of foundation slabs.At a minimum,these measures shall <br /> demonstrate that the proposed project design would meet CBC <br /> and City design standards. <br /> b. During project design and construction,all measures outlined in <br /> project geotechnical reports for the proposed project and,if <br /> necessary,measures included in the supplemental site-specific <br /> geotechnical report(s)shall be implemented to ensure that <br /> project structures and site occupants would be safe during <br /> seismic events. <br /> N <br /> c. The on-site soils will likely be saturated by rainfall in the winter <br /> and early spring months.If the construction schedule requires <br /> continued work during the wet months,the City shall consult <br /> with a qualified civil engineer and implement any additional <br /> recommendations provided,as conditions warrant. <br /> 4.7-3: Construction-Related Erosion Hazards.Based on soil PS 4.7-3:Construction-Related Erosion Hazards.
