Schedule

Start FY 2022 / Finish FY 2036

Funding

Safe, Clean Water Fund ($13.2 million)

This project supports ongoing development and maintenance of a robust flood forecasting system. The system facilitates the efficient dissemination of information to emergency responders and the public.

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

In FY26 Quarter 3 (January 2026 – March 2026),

Testing of the text-based flood notification system was successfully completed. Public release is planned for Fall 2026.
Routine enhancements to the internal alert system are ongoing. These enhancements improve notifications for operations staff and key stakeholders regarding creek levels, reservoir conditions, and rainfall, increasing overall effectiveness and system reliability.
Code updates were deployed to integrate the new version of the USGS API, ensuring uninterrupted access to station data. The old APIs were deprecated by USGS.
High-resolution cameras are currently being tested to improve monitoring of hard-to-access critical sites.
Improvements to data acquisition and processing pipelines are ongoing and will continue as part of routine system maintenance, enhancing data accuracy and speed over time.
Upgrades to the ALERT website are ongoing and will continue to improve usability, as well as the accuracy and reliability of publicly shared data.
Enhancements to the near real-time weather data processing system are ongoing and will continue to support continuous improvement in flood impact estimation.
A machine learning–based flood forecasting model is in testing and is expected to enhance real-time prediction capabilities alongside existing methods.
Initial results have been produced from a multi-year research study on the influence of large-scale and global weather patterns on the San Francisco Bay Area. These findings are expected to improve understanding of significant regional weather events and support both daily operations and emergency management.

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.

View the Safe, Clean Water Program’s annual reports, annual IMC audit reports, and independent audits, including a staff response, on the Valley Water website.

Valley Water invites you to attend a public hearing regarding proposed changes to the San Francisquito Creek Flood Protection Project and Good Neighbor Programs within the Safe, Clean Water Program.
