Document Description
Seismic and functional upgrades to the Upper Crystal Springs Dam Culverts, including seismic strengthening of the Lower Culvert, which crosses the San Andreas Fault rupture zones. Seismic improvements to the Crystal Springs Outlet Structures 1 and 2, including removal of the seismically vulnerable aboveground portions of the towers, and construction of a small onshore control shed for remote valve operation. Major seismic upgrade of the Crystal Springs Pump Station (CS Pump Station), including construction of a new, seismically strengthened Pump Station, and replacement of all related facilities, pipelines, and pipeline connections. The upgrade would also include increasing the pump station booster capability to 120 million gallons per day to meet delivery reliability goals, and construction of a new dissipation structure for releases into San Mateo Creek to meet anticipated DSOD requirements. Seismic upgrades to the existing CS/SA Pipeline that conveys water from CS Pump Station to San Andreas Reservoir (~4.7 miles), including replacement of 2 segments of the pipeline, general pipeline improvements (i.e., corrosion protection, replacement of valves, etc.), and new access roads to ensure access to the pipeline for emergency and maintenance repairs. Seismic upgrade to the San Andreas Outlet Structures 2 and 3, including improvements at both the outlet towers and tunnel portals located at the Harry Tracy Water Treatment Plant. Implementation of habitat mitigation sites including, but not limited to, full implementation of the San Andreas and Adobe Gulch habitat improvements sites.
