Document Description
The San Francisco Public Utilities Commission (SFPUC) proposes to conduct geotechnical investigations at several sites within the SFPUC Peninsula watershed land in unincorporated San Mateo County. These investigations would increase the SFPUC's understanding of local site conditions crucial to successful implementation of the proposed Habitat Reserve Program (HRP) and the Crystal Springs San Andreas Transmission Upgrade Project (CSSA Project) in the SFPUC Peninsula watershed by identifying the geologic, hydrologic, and seismic conditions project areas. The proposed geotechnical investigations for the HRP consists of the installation of ~17 piezometers (water pressure meters) in boreholes as well as trenches, 2 soil test pits, 28 hand augured soil testing sites, and 20 surface soil sampling sites. The proposed geotechnical studies in support of the CSSA Project would consist of up to 5 trenches to locate the San Andreas Fault and determine its slip rate. No permanent facilities would be developed as part of the proposed project. All proposed activities would take place within the boundaries of SFPUC-owned watershed land. The hRP geotechnical investigations would occur over an ~3 week long period, with work at individual sites taking one day or less. The fault trenches that would be conducted in support of the CSSA Project would require ~3 weeks for excavation and mapping. The geotechnical investigations are expected to occur between January 2010 and September 2010.
