B2: Interagency Urban Runoff Program*

About This Project

This project supports the District’s continued participation in the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) and South County programs that help the District reduce stormwater pollution and meet regulatory requirements to reduce contaminants in surface water.

The District also participates in the regulatory development process related to stormwater by providing review, analysis and commentary on various basin plan amendments, Total Maximum Daily Loads (TMDLs) and water bodies listed as impaired or threatened under the federal Clean Water Act. Project B2 also allows the District to maintain regional public education and outreach activities to help prevent urban runoff pollution at the source.


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

Pollution prevention activities 

  • Pollution Prevention Activity #1: South County Pajaro River Watershed Pathogen and Microbial Source Tracking Study - field monitoring was completed in April 2016, assisted in further monitoring of pathogen sources. A final project report was completed. (Pajaro River Watershed Microbial Source)

  • Pollution Prevention Activity #2: South County Nutrient Program - The Pajaro River Basin Nutrient TMDL affects agricultural growers and municipalities in south Santa Clara County. Performed a spatial data analysis identifying agricultural parcels vulnerable to nutrient and pesticide pollution. The analysis was presented to the South County stormwater group. The District is currently developing next steps to reduce nutrient loading in the Uvas/Llagas Watershed.

      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, the District 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.
