Soil liquefaction occurs when loose soil deposits below the water table are subject to large ground accelerations generated from seismic events. According to the City's General Plan Land Use Element ErR, the project site is located in an area that is characterized with low liquefaction hazard potential. To minimize potential liquefaction impacts, the proposed project would be subject Seismic Shaking Standards of the Uniform Building Code. Compliance with the Uniform Building Code would reduce potential liquefaction impacts to a level considered less than significant. A-4. Landslides No Impact The project site is flat without any topographical relief. According to the City's General Plan, there are no landslide planes on the project site. Therefore, implementation of the project would not result in adverse impacts in regards to landslides. B. Would the project result in substantial soil erosion or the loss of topsoil? Potentially Significant Unless Mitigation Incorporated Erosion refers to the removal surfaces by water or wind. intensified with an increase in channels and by the removal of soil exposed. of soil from exposed bedrock The effects of erosion are slope, the narrowing of runoff groundcover, which leaves the Construction operations for the proposed proj ect would require the excavation of onsite soils. The uncovered soils on the project site could potentially result in erosion and sedimentation impacts to onsite and offsite drainage facilities. This potential impact could increase during periods of rain. To reduce potential erosion impacts to a level considered less than significant, the following mitigation measure shall be implemented. Mitigation Measure · Prior to the issuance of a grading permit the applicant shall submit for review and approval a surface drainage/grading plan/erosion control plan, prepared by a 9 31A-31 11 of 48
