E7: San Francisco Bay Shoreline Study

This project is a partnership with the California State Coastal Conservancy, the U.S. Army Corps of Engineers (Corps) and regional stakeholders. The purpose of the San Francisco Bay Shoreline Study is to: provide tidal flood protection, restore and enhance tidal marsh and related habitats, and provide recreational and public access opportunities. Initial design and construction for flood protection is planned for Economic Impact Area 11 (EIA11), which is the urban area of North San Jose and includes the community of Alviso and the San Jose-Santa Clara Regional Wastewater Facility. The project relies on federal participation from the Corps. Without federal participation, the district cannot implement additional planning, design and construction due to limited available funding.

Planning efforts for the other EIAs 1-10 are currently ongoing to assess potential tidal vulnerability of the areas behind the existing shoreline levees with three future sea level rise scenarios on a risk and uncertainty basis. The study effort will also evaluate cost/benefit for the preferred alternative of a protective shoreline levee under one percent tidal flood protection with three sea level rise conditions.

The proposed Safe, Clean Water funding provides the district’s cost share to complete the planning study for the full project area, and provides a portion of the district’s cost share toward construction of flood protection improvements in the North San Jose (EIA11) area, in and near Alviso.

  • Provides planning and design to protect nearly 4,700 acres and more than 5,000 structures, including roads, highways, parks, airports and sewage treatment plants in all of Santa Clara County
  • Provides educational, recreational, and public access opportunities in all of Santa Clara County
  • Protects more than 1,100 structures and a population at risk of 5,500 in EIA11
  • Allows for the restoration of 2,900 acres of tidal marsh and related habitats in EIA 11
  • Provides educational, recreational, and public access opportunities

Project Status

(As of June 2017)

The study effort for EIAs 1-10 will now focus on preparing material for a workshop meeting with the Corps which is anticipated in late 2017, pending Corps receipt of federal funding.

Key Performance Indicators

  1. Provide portion of the local share of funding for planning and design phases for the former salt production ponds and Santa Clara County shoreline area

  2. Provide portion of the local share of funding toward estimated cost of initial project phase (Economic Impact Area 11)
