Soil liquefaction occurs when loose soil deposits below the water table are subjected to large ground accelerations generated from seismic events. Liquefaction is generally known to occur in saturated cohesionless soils at depths shallower than about 50-feet. According to the City's General Plan Land Use Element EIR, the project site is considered to have very low potential for liquefaction hazard impacts. The proposed project involves the remodeling of an existing building. Implementation of the proposed proj ect would not increase the risk for liquefaction impacts. Additionally, the proposed proj ect would be subj ect to the seismic safety standards of the Uniform Building Code. Compliance with the Uniform Building Code would reduce potential liquefaction hazard impacts to a level considered less than significant. A-4. Landslides No Impact The project area is flat without any topographical relief. According to City's General Plan Land Use Element EIR, there are no landslide planes or slopes on the proj ect si te. Therefore, implementation of the proj ect would not result in adverse impacts in regards to landslides. B. Would the proj ect result in substantial soil erosion or the loss of topsoil? No Impact Erosion refers to the removal of soil from exposed bedrock surfaces by water or wind. The effects of erosion are intensified with an increase in slope, the narrowing of runoff channels and by the removal of groundcover, which leaves the soil exposed. Construction operations for the proposed project would not require excavation and grading activities that would uncover soils on the project site. Therefore, implementation of the proposed project would not result in erosion and sedimentation impacts to onsite and offsite drainage facilities. c. Would the project result in the loss of a unique geological feature? 9 75~:~~18
