E1: Coyote Creek Flood Protection*

About This Project

This project is to plan, design and construct improvements along approximately nine (9) miles of Coyote Creek, between Montague Expressway and Tully Road, in San José. The primary objective is to provide protection from floods up to the level that occurred on February 21, 2017, equivalent to approximately a 5% flood (20-year event). In December 2019, the Valley Water Board of Directors voted to allocate local funding for construction of the preferred project; however, Valley Water is also exploring additional external funding sources and partnership opportunities.

Since 2017, Valley Water has implemented several short-term interim projects to help reduce the risk of flooding along Coyote Creek. These include the installation of an interim floodwall and embankment along the creek in the Rock Springs community. This structure protects the Rock Springs community from a flood event equivalent to the February 2017 flood. Other interim projects include repairing a 150-foot levee adjacent to the South Bay Mobile Home Park, installing flood gauges on bridges that provide real-time visual information on water levels and removing invasive vegetation from Valley Water and City property in parts of the creek that experienced the most flooding.

*This project was voter approved as part of the Safe, Clean Water and Natural Flood Protection Program.

The Coyote Creek Flood Protection Project comprises two projects: the Coyote Creek Flood Management Measures for the FERC Order Compliance Project (CCFMMP or Phase 1) and the Coyote Creek Flood Protection Project (CCFPP or Phase 2). The CCFPP is in the design phase, with staff actively evaluating critical data from various sections along Coyote Creek. The map to the right shows reaches 5 and sections of 6 and 7, as part of the CCFMMP, which are in construction and last through the end of 2024. Reaches 4, 8, and parts of 6 and 7 are part of the CCFPP, with construction anticipated to start in mid-2025 and be completed by the end of 2027. Reaches are sections where the work will take place along the creek.  

The CCFPP is currently in the design phase, with various flood reduction elements proposed at different locations along nine miles of Coyote Creek to provide flood protection to the 2017 level of flooding.

Current construction work and sites
Coyote Creek Flood Management Measures Project (CCFMMP) construction started in June 2023. Floodwalls will be installed along various sections of Coyote Creek between Old Oakland Road and Highway 280. Below are maps of the reaches where work is scheduled for the CCFMMP.

Reach 5: San Jose Municipal Golf Course to Mabury Rd and creek ownership map.

Valley Water’s project activities include the installation of floodwalls. To build them, workers will install metal pieces called sheet piles along Coyote Creek, using a press-in method that produces low noise. Some neighboring properties may experience typical construction noise and minor vibrations during this effort. The work is scheduled for Monday through Friday, from 7 a.m. to 7 p.m.

Crews will be installing floodwalls along the west bank of Coyote Creek north and south of Berryessa Rd. and on a portion of Notting Hill Dr. You can expect construction trucks traveling on Old Oakland Rd., Murphy Ave., Lundy Ave., Sierra Rd., Hazlett Wy., Notting Hill Dr., Chessington Dr., Berryessa Rd., Commercial St., Mabury Rd., King Rd., Timothy Dr., and Yard Ct.

Please use caution when driving near the project areas and follow all traffic control measures. Flaggers will be present to guide vehicles and pedestrians safely.

Reach 6Mabury Rd. to U.S. Highway 101 and creek ownership map
Details to be provided once the work in this section is scheduled. 

Reach 7: Santa Clara Street to South end of William Street Park and creek ownership map
Construction of the Coyote Creek Flood Management Measures Project from Santa Clara St. to Margaret St. in San Jose is tentatively scheduled to start on Nov. 27, 2023, with crews set to prepare the site for equipment access, tree removal and vegetation clearing. Floodwall installation in this section of the creek will begin after the site preparations and continue through March 2024. 

Should weekend work be needed, impacted neighbors will be informed. Construction activities will also include demolishing two structures and a garage located south of the E. Santa Clara St. fire station along E. 17th St. The cleared area will be restored with native tree and vegetation plantings.

During the project work, you can expect noise, dust and minor vibrations typical of construction efforts. Additionally, there will be large construction vehicles travelling on E. William St., E. San Salvador St., E. San Carlos St., E. Santa Clara St., Arroyo Way., S. 16th St., and S. 17th St. Please use caution when near the project area and follow all traffic control measures. Flaggers will be present to safely guide vehicles and pedestrians. The construction equipment staging area will be at the Coyote Creek Outdoor Classroom on E. William St. Nearby parking may be limited during scheduled project work hours. The map contains information on the location of planned construction activities.

      History & Background

      Flooding History 

      Flooding has occurred many times within the Coyote Creek Watershed, including along portions of Coyote Creek in 1911, 1917, 1931, 1958, 1969, 1982, 1983, 1997, 1998, and 2017. The largest flow recorded on Coyote Creek was 25,000 cubic feet per second in 1911, before the construction of the current two water-supply reservoirs in the upper watershed. The worst flooding in the project reach since Anderson Reservoir was constructed in 1950 occurred in February 2017. Coyote Creek overtopped its banks at several locations between Montague Expressway and Tully Road. Businesses and hundreds of homes were inundated by creek waters for many hours. Highway 101 near Watson Park and various local streets were closed due to flooding, and thousands of residents had to be evacuated and sheltered.

      Project Background

      The Coyote Creek Flood Protection Project was initially part of the voter-approved Clean, Safe Creeks and Natural Flood Protection Plan (CSC Plan) that came into effect in Fiscal Year 2001-2002 (FY02). The project entailed planning, designing, and partially constructing flood protection measures along an approximately six-mile stretch of Coyote Creek, extending upstream of Montague Expressway to Interstate 280. The project objective was to protect 1,400 parcels from 1% flood eventually. 

      Under the CSC Plan, Valley Water performed geomorphic and floodplain analysis, prepared a problem definition report, held multiple community meetings to receive input, completed conceptual alternatives analysis, and prepared the Planning Study Report (PSR). A range of conceptual alternatives was developed to address the Coyote Creek Project objectives and the cost of all the alternatives significantly exceeded the project budget. In 2011, the 100-year (1%) flood risk reduction improvements cost was estimated between $500 million and $1 billion. With no federal funding, Valley Water proceeded to design only the downstream reaches of the Coyote Creek Project (Montague Expressway to Highway 880). 

      Voters Approve the 2012 Safe, Clean Water Program

      In November 2012, voters approved the Safe, Clean Water and Natural Flood Protection Program (2012 Program), which replaced the CSC Plan. The project was continued in the 2012 Program with the key performance indicator (KPI) to “Complete construction of downstream project elements.” 

      The project was delayed due to various developments, including extremely high project cost estimates and the absence of federal funding, which was critical to Valley Water’s ability to construct the project. Furthermore, potentially feasible project alternatives for a 1% level of protection depended significantly on the outcome of various ongoing projects, including the Anderson Dam Seismic Retrofit Project, which could impact the flows into Coyote Creek. As a result, in FY16, the project was placed on hold until FY19.

      After significant flooding in 2017, the project was modified to extend the project reach by approximately 2.9 miles upstream to Tully Road to include the Rock Springs neighborhood and incorporate the areas impacted by the flood event. In addition, the target protection level was revised to match the February 2017 flood (approximately a 20-to 25-year event), which was the largest flow seen in Coyote Creek since 1950. This allowed Valley Water to address the flood threat to the community without depending on the progress of other projects and their impacts on Coyote Creek flows. Furthermore, Valley Water implemented short-term relief solutions to reduce flood risk. Details about the 2017 modification can be found at

      Following a February 2020 direction from the Federal Energy Regulatory Commission (FERC) regarding the Anderson Dam Seismic Retrofit Project, the Coyote Creek Project was split into two projects: the Coyote Creek Flood Management Measures Project (CCFMMP) and the Coyote Creek Flood Protection Project (CCFPP). The CCFMMP focuses on building flood management measures to handle potential releases from the larger outlet tunnel at Anderson Dam. 

      Voters Approve the Renewed Safe, Clean Water Program

      In November 2020, voters approved the renewed Safe, Clean Water and Natural Flood Protection Program (Safe, Clean Water Program), replacing the 2012 Program. The project has continued in the renewed Safe, Clean Water Program.

      About the Safe, Clean Water and Natural Flood Protection Program

      In November 2020, voters in Santa Clara County overwhelmingly approved Measure S, a renewal of Valley Water’s Safe, Clean Water and Natural Flood Protection Program.

      The program was first passed by voters in 2000 as the Clean, Safe Creeks and Natural Flood Protection Plan, then again in 2012 as the Safe, Clean Water and Natural Flood Protection Program. The renewal of the Safe, Clean Water Program will continue to provide approximately $47 million annually for local projects that deliver safe, clean water, natural flood protection, and environmental stewardship to all the communities we serve in Santa Clara County.

      While evaluating ways to improve the 2012 program, Valley Water gathered feedback from more than 21,000 community members. That helped Valley Water create the six priorities for the renewed Safe, Clean Water Program, which are:

      Priority A: Ensure a Safe, Reliable Water Supply

      Priority B: Reduce Toxins, Hazards and Contaminants in our Waterways

      Priority C: Protect our Water Supply and Dams from Earthquakes and Other Natural Disasters

      Priority D: Restore Wildlife Habitat and Provide Open Space

      Priority E: Provide Flood Protection to Homes, Businesses, Schools, Streets and Highways

      Priority F: Support Public Health and Public Safety for Our Community

      Each year, Valley Water prepares a report providing a progress update for each of these program priorities, along with fiscal year accomplishments.

      To ensure transparency and accountability to the voters, the ballot measure also created an Independent Monitoring Committee, appointed by the Santa Clara Valley Water District Board of Directors. The Independent Monitoring Committee annually reviews the program’s progress to ensure the outcomes are achieved in a cost-efficient manner and reports its findings to the Board. Additionally, the IMC also reviews each proposed 5-year implementation plan prior to its submittal for Board approval.

      In addition, the program requires three independent audits.
