The Hayward Fault is located about 15 miles east of the R-2 project <br />zoning districts, and the Calaveras Fau~ is located about 21 miles east/southeast of the zoning <br />districts. The San Andreas Fault is located approximately 3 miles west of the zoning districts, and is <br />the closest major fault. However, no active fault traces are found at or in the immediate vicinity of the <br />districts, and the site is not located within an Alquist-Priolo Earthquake Fault Zone (Special Study <br />Zone). Therefore, the project would have a less than significant risk from earthquakes and related <br />seismic activity. <br /> <br />The project would have a less than significant impact from seismic-related ground failure, including <br />liquefaction. Site-specific geological and soil conditions will be reviewed at the time of specific <br />developments, and soil remediation and compacting measures will be conditioned where warranted. <br />These would include residential development proposals within the Redwood Shores R-2 zoning district <br />where the USGS has identified high potential for liquefaction. The other R-2 zoning area of Friendly <br />Acres, Oakwood and West Woodside are located in areas with medium liquefaction susceptibility, <br />similar to much of Redwood City. <br /> <br />The project would have no impact from landslides, as none of the R-2 areas are located in terrain with <br />steep slopes which could be susceptible to landslides. <br /> <br />"17l <br /> <br />City of Redwood City, Planning, Housing and Economic Development Department <br />
