E7: San Francisco Bay Shoreline Study

This project is a partnership with the California State Coastal Conservancy, the U.S. Army Corps of Engineers (USACE) and regional stakeholders to provide tidal flood protection, restore and enhance tidal marsh and related habitats, and provide recreational and public access opportunities. Initial construction for flood protection is planned for Economic Impact Area  (EIA) 11, which is the urban area of North San Jose and includes the community of Alviso. The project relies on federal participation from the USACE to review and approve the plans. Without federal participation, the istrict cannot implement additional planning, design and construction due to limited available funding. The proposed Safe, Clean Water funding provides the District’s cost share to complete the planning study for EIAs 1-10, and provides a portion of the District’s cost share toward design and construction of flood protection improvements in the North San Jose (EIA11), in and near Alviso.

Benefits

  • Protects more than 1,000 structures and 100 non-residential structures 
  • 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
  • Allows for the restoration of 2,900 acres of tidal marsh and related habitats (EIA 11)
  • Provides educational, recreational, and public access opportunities


Project Status

(As of June 2017)

  • The USACE 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.

    In July of 2016, the partnering agencies signed a design agreement to begin the design phase. Design and construction will be conducted in phases beginning with Reach 1 which is from the Alviso Marina to the Union Pacific Railroad. Reach 1 levee design began in October and is scheduled to be completed by December 2017. Concurrently the partnering agencies are coordinating with the permitting agencies to secure permits by early 2018. If permits can be secured, construction of Reach 1 could begin in 2018, however, to begin construction the project also requires USACE construction authorization and a signed construction partnership agreement. This project has strong federal support and the study partners are hopeful construction authorization will occur to support construction to begin in 2018.

  • EIAs 1-10: Ahead of working with the USACE on the next EIA or set of EIAs, the district began a Preliminary Feasibility Study for EIAs 1 -10. The preliminary study’s goal was to identify a preliminary 1-percent tidal flood risk management alignment and its related benefits and costs for the EIAs 1-10 coastal area to aid in determining the district’s next study phase or phases and to identify potential study partners. The preliminary alignment was identified in June 2015 and was used to move forward with conducting the study analysis.

    The 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 Mid-Peninsula Open Space Authority were all consulted in the identification of the preliminary alignment. In March 2017, the Preliminary Feasibility Study for EIAs 1-10 was completed and finalized. Prior to finalizing the report, a meeting was held with the consultant agenices to fully discuss the final report. 

    Final Preliminary Feasibility Study for South San Francisco Bay Shoreline 

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