2012 C2: Emergency Response Upgrades*

About This Project

This project covers the development of an automated flood warning system that uses real-time rainfall data to predict stream flows and potential flood risk. The system efficiently disseminates information to emergency responders and the public using the web, text, automated calls and other technologies, allowing more time to activate flood-fighting measures and reduce flood damage.

 

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

This past winter was relatively dry which resulted in very little live testing of the flood forecast system. The current system has 5 general locations: Upper Guadalupe River (which includes Ross Creek and Guadalupe River); West Little Llagas Creek; San Francisquito Creek; Uvas Creek; and Upper Penitencia Creek. Additionally, reservoir inflows are included for many Valley Water facilities.

We have also launched a beta version of the new ALERT surface water monitoring website. This new site is under testing and consolidates several existing web pages which display recorded sensor data and flood stages. In addition, the stream and reservoir forecasts are also being displayed.

Coordination continues with NOAA’s Advanced Quantitative Precipitation Information (AQPI) Project, with NOAA working on providing an additional “blend forecast”, which will combine their best short, mid, and long range rainfall forecasting models.

    History & Background

    About the Safe, Clean Water and Natural Flood Protection Program

    In November 2012 the voters of Santa Clara County overwhelmingly approved Measure B, the Safe, Clean Water and Natural Flood Protection Program, as a countywide special parcel tax for 15 years with a sunset date of June 30, 2028. This Program replaced the Clean, Safe Creeks and Natural Flood Protection Plan, which voters approved in November 2000.

    The Safe, Clean Water Program was developed with input from more than 16,000 residents and stakeholders and was created to match the community’s needs and values. The voters of Santa Clara County identified five priorities:

    Priority A: Ensure a Safe, Reliable Water Supply

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

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

    Priority D: Restore Wildlife Habitat and Provide Open Space

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

    Other: Six projects from the Clean, Safe, Creeks Plan have been carried forward into the Safe, Clean Water Program.  

    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.

    In addition, the Program requires three independent audits, the first of which was conducted in FY 2017.
