Refer to Division of Mines and Geology Special <br />Publication 4Z <br />No Impact. Southern California, including the project area, is subject to the effects of seismic activity <br />due to the active faults that traverse the area. Active faults are defined as those that have experienced <br />surface displacement within Holocene time (approximately the last 11,000 years) and/or are in a State- <br />designated Alquist-Priolo Earthquake Fault Zone. <br />According to the Seismic Safety Element of the City's General Plan, no faults (active, potentially active, <br />or inactive) are known to exist within the City. Since no known faults exist in the site vicinity and the <br />site is not located within an Alquist-Priolo Earthquake Fault Zone, impacts would not occur in this <br />regard. <br />Mitigation Measures: No mitigation is required. <br />JULY 2011 4.6-1 GEOLOGY AND SOILS <br />31A-51
