SAN FRANCISQUITO CREEK, CALIFORNIA
CONTINUING AUTHORITIES PROGRAM, SECTION 205
PROJECT LOCATION AND DESCRIPTION
The U.S. Army Corps of Engineers, San Francisco District (USACE), in partnership with the non-federal sponsor, the San Francisquito Creek Joint Powers Authority (SFCJPA) – a regional government agency whose members are the Cities of Palo Alto, Menlo Park, and East Palo Alto; the San Mateo County Flood Control District, and the Santa Clara Valley Water District – has reinitiated the San Francisquito Creek Flood Risk Management Feasibility Study under the authority of Section 205 of the Continuing Authorities Program (CAP) of the River and Harbor Act of 1962 (P.L. 87-874), as amended, to continue to evaluate alternatives for managing the risk of fluvial flooding along San Francisquito Creek. The study area is generally the San Francisquito Creek from Highway 101 to El Camino Real (commonly known as Reach 2).
San Francisquito Creek has a well-documented history of flooding, with documented flood events occurring in 1955, 1958, 1986, 1998, 2005, and 2012. The flood of record occurred in 1998 and resulted in $28 Million in documented damages. This event has been estimated to be nearly a 2% Annual Chance of Exceedance (ACE) (50-year) flood event. The third largest flow on record occurred in 2012 and resulted in $9 Million in documented damages. The second largest flow of record occurred in 1955, but economic damages from that event were not well documented.
Alternatives for consideration will consist of one or more measures and will include both structural and non-structural measures. Structural measures under consideration include levees, floodwalls, channel widening, channel smoothing, by-pass culvert, and detention basin. Non-structural measures include flood warning systems, relocation of structures out of the floodplain, flood insurance, and floodplain management plan.
FY 21 ACCOMPLISHMENTS
- Executed a Feasibility Cost Sharing Agreement
- Project kickoff
- Continued feasibility analysis
ISSUES AND OTHER INFORMATION
This study was converted from General Investigations (GI) to CAP Section 205. A feasibility study for San Francisquito Creek was initiated in 2005, in accordance with the Flood Control Act of 1941, P.L. 77-228, 55 Stat. 638 (July 24, 1941). The tentatively selected plan was identified in October 2018 and included widening sections of the channel and replacing the Pope Chaucer Street Bridge in Reach 2. The project cost of the tentatively selected plan was found to potentially fit within the federal cost limit for CAP Section 205 ($10 million Fed, cost shared 65% / 35%). The study was converted to CAP Section 205 in June 2021 and the study team will continue the feasibility level analysis in partnership with the SFCJPA.
