City of San Leandro
<br />Housing Element Update (2015-2023) Project
<br />Initial Study and Environmental Checklist
<br />a) Would the project expose people or structures to potential substantial adverse effects, including the risk of loss, injury or
<br />death involving. i) rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault
<br />Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Di-
<br />vision of Mines and Geology Special Publication 42; ii) strong seismic round shaking iii) seismic-relatedground failure, in-
<br />cluding liquefaction; iv) landslides, mudslides, or other similar bazards?
<br />San Leandro is listed as a city affected by Alquist-Priolo Earthquake Fault Zones, according to the California
<br />Geological Survey.23 However, while two of the city's available housing sites are located within the Alquist-
<br />Priolo Special Studies Zone, as previously discussed, adoption of the Housing Element would not result in
<br />physical development, nor does it propose specific projects. Rather, the Housing Element only identifies
<br />available sites for future residential development that have previously been zoned for residential use. Residen-
<br />tial development under the Housing Element would be subject to future project -level review and approval to
<br />identify site-specific hazards. Further, compliance with existing federal, State, and local regulations and the
<br />goals, polices, and actions of the 2002 General Plan Environmental Hazards Element, with respect to geolog-
<br />ical and seismic hazards would ensure that the impacts associate with seismic hazards are minimized to the
<br />maximum extent practicable. In addition, City engineering standards require that development in geologically
