Santa Clara County, California, USA

The Santa Clara Valley Water District (District) selected HDR to provide planning, environmental and permitting services for the Seismic Retrofit of Anderson Dam. Anderson Dam is the District's largest reservoir (90,400 acre-feet), housing a critical water supply facility for Santa Clara County, California.

This project is the first of several major projects being completed under the District's Dam Safety Program. Successful and timely completion of this project is necessary to meet seismic standards that address the concerns of the Federal Energy Regulatory Commission and the California Division of Safety of Dams, as well as to provide improved public safety.

The project team will be responsible for the development and preparation of planning study documents, including the Problem Definition Report, conceptual engineering evaluations and design, a Planning Study Report, and CEQA/NEPA documents, as well as other project permitting. The ultimate outcome of the planning services will be to recommend a preferred alternative to:

  • Resolve the seismic deficiencies in the dam embankment from the maximum credible earthquake;
  • Resolve and remediate, if necessary, the outlet works for the potential fault rupture risks; and
  • Review and revise the Probable Maximum Flood for the dam, perform flood routing evaluations and develop corrective actions required to address possible deficiencies with the spillway and embankment freeboard.
  • Professional Services: Upgrades, Retrofits and Modifications
  • Project Type: Dams and Hydraulic Structures
  • Related Projects: Water, Water Resource Management
