<br />Shea Homes Residential Project <br />Environmental Impact Report <br /> <br />Findings and Facts in Support of Findings <br /> <br />Facts in Support ofthe Finding Related to Geology <br /> <br />Implementation of Mitigation Measure G-l would substantially lessen the adverse impacts of the <br />Shea Homes Residential Proj ect related to erosion impacts to a level that would be less than <br />significant. <br /> <br />G-l Prior to issuance of grading permits the project developer shall provide proof of coverage <br />under NPDES General Construction Activity Storm Water Permit that includes a copy of <br />the project's permit issued by the State Water Resources Control Board that identifies the <br />project's permit number and two copies of the Storm Water Pollution Prevention Plan. <br /> <br />Level of Significance of Impacts Related to Geology Impacts <br /> <br />The adverse impacts of the Shea Homes Residential Project related to geologic impacts would be <br />mitigated to below a level of significance based on the implementation of Mitigation Measure <br />G-I, provided above. <br /> <br />4.2.3.1 Impacts Related to Impacts to Geology <br /> <br />According to the preliminary geotechnical report prepared for the proj ect site, the soil conditions <br />on the project site are suitable for the development of the proposed project. However, a <br />construction-level geotechnical report would be needed to evaluate site specific soil liquefaction <br />constraints, soil conditions, building load requirements and to identify design recommendations <br />to ensure the geotechnical stability of the proj ect site. <br /> <br />Findings Related to Geology <br /> <br />A mitigation measure has been incorporated into the project, which avoid or substantially lessen the <br />significant environmental effect as identified in the EIR. <br /> <br />Facts in Support of the Finding Related to Geology <br /> <br />Implementation of Mitigation Measure G-2 below would substantially lessen the adverse impacts <br />of the Shea Homes Residential Project related to geology impacts to a level that would be less <br />than significant. <br /> <br />G-2 Prior to issuance of grading permits a construction-level geotechnical report shall be <br />submitted for review and approval to the Building Department and/or Public Works <br />Agency. The report shall address the potential for seismically induced soil liquefaction <br />and soil instability. Based on the study detailed grading recommendations and foundation <br />design criteria shall be provided. <br /> <br />Level of Significance of Impacts Related to Geology Impacts <br /> <br />The adverse impacts of the Shea Homes Residential Project related to geologic impacts would be <br />mitigated to below a level of significance based on the implementation of Mitigation Measure <br /> <br />Page 9 <br /> <br />75G",7a6 <br />
