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.
The forecasting software has been moved to the cloud and is running several forecasts:
- 7-day forecast from Fox Weather (meteorological consultant);
- 18-hr High Resolution Rapid Refresh (HRRR) forecast from the National Oceanic and Atmospheric Administration (NOAA); and
- 10-day forecast from Scripps Institution of Oceanography’s Center for Western Weather and Water Extremes (CW3E).
In addition, Valley Water receives reservoir inflow forecasts from the California Nevada River Forecast Center, augmenting the existing forecasts. No new forecast points are planned, as the focus remains on leveraging precipitation data and improving the runoff model.
These forecasts have worked well during the recent wet January and have been very beneficial in Valley Water operations.
No current documents.

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.
