<br />VI. GEOLOGY/SOILS <br /> <br />The following analysis is based on a Geotechnical Engineering <br />Evaluation prepared by Nunez Engineering in May of 2002. The <br />Geotechnical Investigation is available for review at the City <br />of Santa Ana Planning Department. <br /> <br />A-l. <br /> <br />Rupture of a known earthquake fault, as delineated on the <br />most recent Alquist-Priolo Earthquake Fault Zoning Map <br />issued by the State geologist for the area or based on <br />other substantial evidence of a known fault? <br /> <br />No Impact <br /> <br />The Seismic Hazards Mapping Act of 1991 established a statewide <br />seismic hazard mapping and technical advisory program to assist <br />cities and counties in protecting the public health and safety <br />from the effects of strong ground shaking, liquefaction, <br />landslides or other ground failure and other seismic hazards <br />caused by earthquakes. Additionally, the Alquist-Priolo Act <br />directs the State Geologist to delineate regulatory zones that <br />encompass surface traces of active faults that have potential <br />for future surface fault rupture to regulate development near <br />active faults in order to mitigate the hazard of surface fault <br />rupture. <br /> <br />The Tustin Quadrangle Official Map of Seismic Hazard Zones dated <br />January 17, 2001 was reviewed to evaluate the site location <br />relative to mapped zones of required investigation for <br />liquefaction and earthquake-induced land slides. <br />According to the Seismic Hazard Zone Map, the project site is <br />not located within a current Alquist-Priolo "Earthquake Fault <br />Zone for fault surface rupture hazard. The surface traces of any <br />active or potentially active faults are not known to pass <br />directly through or extend towards the project site. Therefore, <br />the potential for surface rupture due to faulting occurring <br />beneath the site during the design life of the proposed project <br />is considered low. <br /> <br />A-2. Strong Seismic Ground shaking? <br /> <br />Less Than Significant Impact <br /> <br />The project site is situated within a highly active seismic <br />region of southern California. A total of 38 active faults have <br />been identified within an approximate 60-mile radius of the <br />project site. The Newport/Inglewood Fault located approximately <br /> <br />9 <br /> <br />31~~rn <br />
