BENDER READY -MIX CONCRETE MANUFACTURING PROJECT (@0 Initial Study /Mitigated Negative Declaration 1 4.6 GEOLOGY AND SOILS J t a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: 1) 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? Refer to Division of Mines and Geology Special Publication 4Z No Impact. Southern California, including the project area, is subject to the effects of seismic activity due to the active faults that traverse the area. Active faults are defined as those that have experienced surface displacement within Holocene time (approximately the last 11,000 years) and /or are in a State - designated Alquist - Priolo Earthquake Fault Zone. According to the Seismic Safety Element of the City's General Plan, no faults (active, potentially active, or inactive) are known to exist within the City. Since no known faults exist in the site vicinity and the site is not located within an Alquist - Priolo Earthquake Fault Zone, impacts would not occur in this regard. Mitigation Measures: No mitigation is required. JULY 2011 4.6-1 GEOLOGY AND SOILS 31A-51 Less Than Would the pm ect Potentially ,. Slgnificant,_ .
