SOUTH SAN FRANCISCO BAY PHASE II INVESTIGATIONS
PROJECT LOCATION AND DESCRIPTION
The South San Francisco Bay Shoreline Phase II study area includes the South San Francisco Bay Shoreline extending from San Francisquito Creek in the city of Palo Alto to the Charleston Slough in the city of Mountain View. The study is examining options to reduce the flood risk in this area, while restoring wetland habitat along the bay shoreline. The Phase II study will evaluate options to reduce the flood risk through both structural and non-structural measures.

TOTAL PROJECT COST
1Includes $200,000 mandatory Independent External Peer Review at 100 percent Federal expense per WRDA 2007.
- The U.S. Army Corps of Engineers (USACE) and the Non-Federal Sponsors (NFS) signed a Feasibility Cost Share Agreement (FCSA) in September 2019
- The Project Delivery Team (PDT) has identified potential alternatives to meet the study purpose and has completed the Alternatives Milestone
- An updated Digital Elevation Model (DEM) was developed for use in the Hydraulics & Hydrology analysis
- The team developed a Wetland Accretion Rate Model for Ecosystem Resilience (WARMER) to evaluate ecosystem restoration benefits
- The team developed a structure inventory of over 5,000 industrial, commercial, and residential structures within the 500-year floodplain
- The team has developed a focused array of alternatives to evaluate for potential project implementation
ISSUES AND OTHER INFORMATION
- Although the study had a smaller scope that initially expected, the time and cost required to complete the study exceeds the constraints of the traditional USACE $3 million and 3-year study effort. The San Francisco District has submitted a waiver request for an exemption from these parameters. USACE Headquarters has approved the total study cost of $6.2Million and the Assistant Secretary of the Army’s office is reviewing the request for extending the total study time by 31 months. The requested schedule would have a Chief’s Report complete in late spring 2025.
