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
(As of December 2016)
- EIA 11: The Shoreline Study completed the Feasibility Phase of EIA 11 on Dec. 18, 2015 when the Chief of Engineers signed the Chief's Report. EIA 11 includes the urban area of North San Jose, the community of Alviso and the San Jose-Santa Clara Regional Wastewater Facility. The report makes a recommendation to Congress to authorize design and construction of EIA 11's recommended plan. The Chief's Report is available to download from here.
On March 22, 2016, the Water District Board of Directors adopted a resolution certifying the environmental impact report (EIR) for EIA 11. The conformed Board agenda memo is available to download from here. The Corps is in the process of issuing a record of decision for EIA 11's environmental impact statement (EIS).

The Corps has received $3 million to proceed into the Design Phase of EIA 11 in 2016 and is expected to receive another $500,000 in 2017. The Water Resources Development Act of 2016, also known as the Water Infrastructure Improvement for the Nation Act, was signed by President Obama which authorizes the EIA 11 Shoreline Project for construction. The District and State Coastal Conservancy are working closely with the Corps to prepare plans and specifications and secure permits for constructing the first elements of EIA 11, pending continued federal funding, may be as soon as 2008.
- EIAs 1-10: The preliminary coastal flood protection levee alignment along the EIAs 1-10 coastal area was completed by the end of June 2015. This proposed alignment has incorporated all the comments from City of Palo Alto, City of Mountain View, City of Sunnyvale, City of San Jose, NASA Moffett Field, US Fish and Wildlife Service, California State Coastal Conservancy and Mild Peninsula Open Space Authority.
The Feasibility Study for EIAs 1-10 is progressing per schedule. The draft final report was submitted to all concerned agencies for review and comments by end of December 2016. The final report will be completed after the project team has responded and updated the report with all review comments and suggestions in January 2017.
