Why: Pursuant to the California Environmental Quality Act, Santa Clara Valley Water District (Valley Water), as the lead agency for the proposed Anderson Dam Seismic Retrofit Project (Project), has prepared a Draft Environmental Impact Report (EIR) to evaluate environmental impacts of the Project.

The proposed Project is located at Anderson Reservoir and areas along Coyote Creek in Santa Clara County, California. Anderson Reservoir is Valley Water’s largest water storage facility, but due to seismic restrictions has not been able to operate to full capacity since 2009.
The Project involves retrofitting and upgrading Anderson Dam and its associated facilities to meet public safety requirements by the Federal Energy Regulatory Commission (FERC) and California Department of Water Resources Division of Safety of Dams (DSOD). Specifically, the Project will correct dam safety deficiencies that were identified between 2008 and 2016. The Project would allow Valley Water to maximize water supply and related benefits, while avoiding and minimizing environmental impacts. The Project also includes decommissioning the hydroelectric facility at the dam, implementing Conservation Measures along Coyote Creek to avoid and minimize adverse impacts, and conducting habitat and species monitoring during construction.
Upon completion of the dam seismic retrofit, Anderson Reservoir will return to its original storage capacity. For post-construction operations, the Project includes: implementing of Fish and Aquatic Habitat Collaborative Effort Phase 1 reservoir releases (flow measures) at the retrofitted Anderson Dam facility, continuing maintenance of the dam once the retrofit has been completed, operations and maintenance of Conservation Measures, and implementing an adaptive management program to monitor and adaptively manage reservoir releases and Conservation Measures to assure that they achieve their objectives.
The Draft EIR identified significant environmental impacts for the following resource topics: aesthetics, air quality, biological resources (wildlife and terrestrial resources), cultural resources, hydrology, geology and soils, groundwater, water supply, water quality, greenhouse gases, hazards and hazardous materials, noise and vibration, public services, recreation, transportation, tribal cultural resources, and wildfire. Many of these impacts were determined to be less than significant after implementing proposed mitigation measures. However, significant impacts would remain significant and unavoidable for the following resource topics: aesthetics, air quality, biological resources (wildlife), hydrology, water quality, and noise. The Project would not be located on a hazardous waste site listed under Government Code Section 65962.5.
