EXPLANATION: The project area is located within the seismically-active Bay Area, with several faults located within 3-16 mites of the project site, although the area is not included in an Alquist=Priolo Special Studies Zone. Therefore, it is likely that during the lifetime of any future buildings constructed in the project area, they will be subject to seismic shaking and other earthquake-induced effects. The Uniform Building Code requires new building construction to meet requirements for construction in earthquake prone areas, which is intended to n,;n;r,»~ any potential impacts related to seismic events. The project area is currently served by sewers for disposal of wastewater. Future development will be required to connect to the City's sewer system, therefore impacts related to soils types and septic innks are not applicable. Asite-specific geotechnical report has been prepared for the former Yokota Nursery site. This report, which anticipated development of the project site with residential uses, found that on-site soils consisted of silly and sandy clays with a low to' moderate expansion potential. Groundwater was encountered at a depth of 30 feet at the time of drillings. Soil liquefaction potential on the site is anticipated to be low. Because the proposed on-site uses have changed, site- -spe~c~c-a~13~sis~ll~e~gd~r-all~r~ape~es~r-ogosed f~~-~y~19 ' -18caia~n-cam-r . topography and not near a creek or the Bay, potential impacts related to landslides, erosion and modification to streams or bays are . ' not anticipated. The following mitigation measures are recommended in order to reduce potentially significant impacts related to on-site soils arid. grading to a less than significant level: ~ ' • Prior.to Site Plan Review approval for the McKevitt and Batarse Trust sites, the respective future property owners shall be required to submit a site-specific Emil geotechnical report, to be reviewed and approved by the City Engineer and Building Official Any recommendations contained in the reports shall become condititons of approval and be included on the plans submitted for building permit approval. • Prior to issuance of a grading permit for theMcKevitt and Satarse Trust sites, the respective applicants shall submit all information, including a Grading Plan accompanied by.SoiIs Engineering and Engineering Geology Reports, in accordance with requirements of the City of San Leandro Municipal Code Title VII, Chapter.l2. - Marina Square Auto Mall Expansion 5 August 2001 Initial Study Checklist
