Environmental Checklist Geology and Soils Environmental Consistency Checklist Pursuant to CEQA Guidelines Section 15183 51 Action EH-1.1.A: Soils and Geologic Report Require soils and/or geologic reports for development in areas where potentially serious geologic risks exist. These reports should address the degree of hazard, design parameters for the project based on the hazard, and appropriate mitigation measures. San Leandro Municipal Code SLMC Section 7.5.175 details soils and foundations requirements including a Geotechnical Engineer or Civil Engineer review of project plans and specifications before issuing a permit for a building where soil and foundation investigation is required; Geotechnical Engineer or Civil Engineer written field report confirming proper building pad and site preparation activities conform with the soil report and approved plans; and Geotechnical Engineer or Civil Engineer final report confirming that site work conforms to the approved plans, specifications, and investigation associated with the project. SLMC Section 7.12.230 details the measures that erosion control, sedimentation control, and drainage plans must have to ensure that storm water from the project site meets the quality standards dictated by the “Storm Water Management and Discharge Control Program Ordinance No. 92-011,” “Association of Bay Area Governments (ABAG) Manual of Standards for Erosion and Sediment Control Measures,” and the “Handbook for Erosion and Sediment Control.” Project-Specific Impacts Quantum Geotechnical, Inc. prepared a Geotechnical Investigation reporting the geotechnical conditions at the project site in July 2020 (included as Appendix GEO). a.1. Would the project expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? The project site is not located within an Alquist-Priolo Fault Zone (City of San Leandro 2016a). The nearest fault to the site is the Hayward Fault located approximately 0.9 mile east of the project site. The California Geological Survey Seismic Hazard Zones Map for the San Leandro 7.5-Minute Quadrangle excludes the site from areas mapped for fault rupture hazards (Appendix GEO). Therefore, as the site is excluded from fault rupture hazard analysis because of low risk of fault rupture hazard, impacts related to fault hazards would be less than significant. a.2. Would the project expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving strong seismic ground shaking? As with all of the East Bay, the project site is in an area at relatively high risk from seismic shaking. However, the current California Building Code (CBC) contains requirements for structural design, including seismic design specifications. Compliance with mandatory building code structural specifications would result in structures that resist adverse effects from seismic ground-shaking. In addition, the project would be required to comply with recommendations listed in the Geotechnical report (Appendix GEO) in accordance with SLMC Section 7.5.175 which would reduce impacts to structural damage or injuries during strong seismic ground shaking. Therefore, impacts associated to strong seismic ground-shaking would be less than significant.
