<br />According to the project geotechnical report, ~he projec"C <br />is not located within a current Alquist-Priolo Earthquake <br />Zone :or :ault surface rupture hazard. The surface traces <br />active or potentially active faults are not known to pass <br />directly through or extend towards the project site. Therefore, <br />the po~ential 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 />site <br />Fault <br />of any <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 />_n::>aimLOLsQutherp.Ca l ifornia. A total of 3 8 active faults have <br />been identified within an approximate 60-mlle radlus. 6t . th~ <br />project site. The NewportjInglewood Fault located approximately <br />13 miles south from the City of Santa Ana is considered to be <br />one of the most dominant faults in regard to potential seismic <br />shaking impacts. The proj ect site could potentially be subj ect <br />to a maximum credible hori zontal ground acceleration of 0.3 Og <br />from a magnitude 6.9 earthquake along the Ne~~ort/Inglewood <br />fault zone. A seismic event of this scale could potentially <br />result significant damage to the proposed project. However, the <br />seismic risks at the project site would not be considered <br />significantly different from other areas In the southern <br />California region. To minimize potential selsmlC shaking <br />impacts, the proposed proj ect would be subj ect to the seismic <br />safeLY standards of the Uniform Building Code. Compliance with <br />the Uniform Building Code would reduce potential seismic shaking <br />impacts to a level considered less -chan significant. <br /> <br />A-3. Seismic-related ground failure, including liquefaction? <br /> <br />Less Than Significant Impact <br /> <br />Soil liquefaction occurs when loose soil deposits below the <br />water table are subj ected to large ground accelerations <br />generated from seismic events. Liquefaction is generally known <br />to occur in saturated cohesionless soils at depths shallower <br />than about 50-feet. <br /> <br />According to the project geo-cechnical report, the potential for <br />liquefaction impacts would be considered very low. Therefore, <br />implementation of the proposed projecL would result in less than <br />significant liquefaction risks. <br /> <br />10 <br /> <br />75&42 <br />
