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 a High to Very High potential for liquefaction hazard impacts. Through the City's development review process, the proposed project would be required to prepare a geotechnical report that identifies the liquefaction constraints on the project site and geotechnical recommendations to reduce potential liquefaction impacts to a level that would be 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 FEIR, there are no landslide pl'anes or slopes on the project si te. Therefore, implementation of the proj ect 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 Incorporated Significant Impact Unless Mitigation 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. Even though the proposed proj ect would involve a limited amount of grading, uncovered soils on the project site could result in erosion impacts to nearby drainage facilities. The erosion impacts could potentially increase during periods of rain. To reduce potential erosion impacts to a level that would be less than significant, the proposed project would be required to prepare a Storm Water Pollution Prevention Plan and obtain a General Construction Activity Storm Water Permit.
