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). These phases cover a 9-mile stretch of Coyote Creek between Montague Expressway and Tully Road. This area is divided into several geographic segments known as reaches, which are shown on the map to the right.

Phase 1 (CCFMMP) has been completed, and flood risk reduction measures have been constructed in the most vulnerable areas in reaches 5, 6, and 7. Valley Water’s Board of Directors accepted the work as complete and filed the Notice of Completion of Contract in June, 2025.

Phase 2 (CCFPP) is in the final design phase, with staff actively evaluating critical data from various areas along Coyote Creek. This phase will implement the remaining flood risk reduction measures in reaches 4 through 8. Construction is anticipated to commence in mid-2026 and is expected to be completed by the end of 2028.

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 https://scvwd.legistar.com/LegislationDetail.aspx?ID=3064265&GUID=D843FFA6-6EA4-4825-9A8F-76221C76BB82.

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.
