SUMMARY:
BACKGROUND
The Anderson Dam Seismic Retrofit Project (ADSRP) will correct dam seismic deficiencies and meet all current Federal Energy Regulatory Commission (FERC) and California Department of Water Resources, Division of Safety of Dams (DSOD) dam safety design standards. The full reservoir capacity will be restored upon completion of the project.

Valley Water is undertaking the Anderson Dam Federal Energy Regulatory Commission Order Compliance Project (FOCP) to comply with the February 20, 2020, directive from FERC. The construction improvements necessary to complete the FOCP have been grouped into five sub-projects to be completed before the ADSRP construction, including the Anderson Dam Tunnel Project (ADTP) and the Coyote Creek Flood Management Measures Project (CCFMMP). The CCFMMP is considered Phase 1 of the Coyote Creek Flood Protection Project (CCFPP). The CCFPP is funded by the renewed Safe, Clean Water and Natural Flood Protection Program, a special parcel tax overwhelmingly approved by voters in November 2020. The CCFMMP was included as a sub-project in the FOCP to minimize flood risk to downstream urban areas ...
