    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.
