Document Description
The New Crystal Springs Bypass Tunnel (NCSBT) would construct a 4,200 foot long tunnel with a 96-inch diameter steel pipeline below Polhemus Road in an unincorporated area of San Mateo County, on the San Francisco Peninsula. The tunnel would convey drinking water to northern San Mateo County and San Francisco customers. An existing 96-inch prestressed concrete pipeline currently conveys water to these customers. The SFPUC determined that the existing pipeline had been subject to significant geologic hazards from slope instability, which could damage the pipeline and interrupt water service. The proposed tunnel would be located approximately parallel to Polhemus Road with one shaft (South Shaft) located adjacent to a decommissioned SFPUC fluoride confluence with Polhemus Creek. Minor ancillary construction would also occur above ground near the North Shaft area. The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement Number 1600-2007-0503-3 pursuant to Section 1602 of the Fish and Game Code to the project Applicant, Husam Masri, San Francisco Public Utilities Commission.
