SFPUC Lower Crystal Springs Dam Improvement Project
EIR - Draft EIR
The San Francisco Public Utilities Commission (SFPUC) proposes to implement the Lower Crystal Springs Dam Improvements (LCSDI) project to left the operating restrictions on Crystal Springs Reservoir imposed by the California Department of Water Resources, Division of Safety of Dams (DSOD), and to restore the reservoir's historical storage capacity. The project would modify various features at the top and toe of the Lower Crystal Springs Dam. The proposed improvements would enable floodwater associated with the Probable Maximum Flood and other very large and infrequent floods to pass safely over the Lower Crystal Dam. In addition, following completion of the proposed improvements, the SFPCU proposes to modify operations of Crystal Springs Reservoir such that the maximum normal water surface elevation would be 287.8 feet, which is 4 feet higher than the currently restricted level and 4 feet lower than the historical maximum level. The proposed project has a 14-month construction schedule, but the majority of the construction would be completed in 9 months, including periods with 24-hour-per-day construction. All project components are located in an unincorporated area of San Mateo County on lands owned by the City and County of San Francisco.
