PLN200"0030; Comerstone at San Leandro Crossings March 20, 2009 Mitigated Negative Declaration VL IDENTIFICATION OF ENVIRONMENTAL EFFECTS An Initial Study conducted by the City of San Leandro (including an attached checklist) determined that the proposed project may have potential significant environmental impacts, however mitigation measures have been incorporated into the project to reduce these impacts to a less than significant level. This Mitigated Negative Declaration has been preparedin accordance with Section 15070 of the State of California Environmental Quality Act (CEQA) Guidelines. VII. SUMMARY OF MITIGATION MEASURES INCORPORATED INTO PROJECT Population and Housing The proposed project implements land uses set forth in the Downtown San Leandro TOD Strategy and analyzed in the TOD Strategy EIR which was certified in September of 2007. The proposed project, as a development project occurring under the TOD Strategy, would be required to follow the General Plan Policies and the Mitigation Measures Master List set forth in the TOD Strategy EIR. Implementation of mitigation measures, as identified below, would result in less than significant impacts for population and housing, Mitigation Measure #1: The applicant shall implement infill development on vacant or underused sites within residential areas in compliance with General Plan Policy 3.04. Mitigation Measure #2: As provided in Section 6-3014 (b) of the San Leandro Zoning Code, a developer may provide off-site construction, land dedication, credit transfers, in -lieu fees or a combination of these alternatives to satisfy the inclusionary housing requirements, which are being pursued in this case. Implementation of Mitigation Measures #1 and #2 reduce potential population and housing impacts to a less than significant level. Geolo2y and Soils In 2002, the U.S. Geologic Survey (USGS) predicted a 62 percent probability of a magnitude 6.7 or greater earthquake occurring in the San Francisco Bay Area by the year 2032. During a major earthquake on a segment of one of the nearby faults, strong shaking is expected to occur at the project site. The project site is also within a designated liquefaction hazard zone. Strong shaking during an earthquake can result in ground failure such as that associated with soil liquefaction, lateral spreading and cyclic densification. Test borings and cone penetration tests were performed on site by Rockridge Geotechnical on December 22, 2008, and these results were used to evaluate the potential for seismic hazards to occur. Based on preliminary field investigations, potentially significant impacts could occur with geologic hazards associated with strong shaking on a nearby fault and the presence of compressible clay zones below the site. Therefore, mitigation of potential liquefaction hazards is required with project implementation. 2
