<br />. <br /> <br />. <br /> <br />. <br /> <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 horizontal ground acceleration of o. 30g <br />from a magnitude 6.9 earthquake along the Newport/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 seismic shaking <br />impacts, the proposed proj ect would be subj ect to the seismic <br />safety 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 than 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 e.cted 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 proj ect geotechnical report, soils conditions <br />on the proj ect site between 10 and 30 feet are classified as <br />medium dense, between 30 and 50 as dense and higher than 50 as <br />very dense. Most of the soils below a depth of 15-feet, the <br />probable upper limit of groundwater saturation, are classified <br />as dense to very dense. The project geotechnical report <br />concluded that the potential for liquefaëtion at the project <br />site is not likely, nor probable. The upper 5 feet soils, which <br />would be considered the least dense would be removed and <br />compacted. Therefore, implementation of the proposed project <br />would result in less than significant liquefaction risks. <br /> <br />A-4. Landslides <br /> <br />No Impact <br /> <br />The project area is flat without any topographical relief. <br />According to the project geotechnical report, there are no <br />landslide planes or slopes within the project êŒea. Therefore, <br />implementation of the project would not result in adverse <br />impacts in regards to landslides. <br /> <br />10 <br /> <br />3,eÄ~~ <br />
