This project supports the Valley Water’s continued participation in the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) and South County programs that help Valley Water reduce stormwater pollution and meet regulatory requirements to reduce contaminants in surface water.
Valley Water 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 Valley Water to maintain regional public education and outreach activities to help prevent urban runoff pollution at the source.
The project is on schedule and within budget.
Trash capture devices
- All four trash booms are currently deployed. Valley Water staff regularly inspects the booms. Valley Water Staff removed five (5) cubic yards of trash from the Thompson Creek boom in April 2019 and two (2) cubic yards of trash from the Lower Silver Creek boom in May 2019.
Valley Water maintained North County partnerships via the SCVURPPP. Valley Water staff chairs the Management Committee for SCVURPPP.
Valley Water staff represents SCVURPP at the Bay Area Stormwater Management Agencies Association and chairs the Bay Area-wide trash committee.
In December 2016, Valley Water, on behalf of SCVURPPP, was awarded a California Proposition 1 grant to develop a Stormwater Resource Plan for the Santa Clara Basin. The plan under the grant was completed by the State Water Resources Control Board. The Stormwater Resource Plan is coordinated with Valley Water’s One Water Plan and stakeholders from the One Water effort are participating. For more information, visit the Valley Water's One Water Plan website. Please see the Stormwater Resource Plan website for more information: www.scvurppp.org/scvurppp_2018/swrp/.
Valley Water maintained South County partnerships by participating in the South County Stormwater Coordination Committee.
Pollution prevention activities
Pollution Prevention Activity #1: South County Pajaro River Watershed Pathogen and Microbial Source Tracking Study
Valley Water staff completed field monitoring in April 2016, assisted in further monitoring of pathogen sources, and prepared a final project report (Pajaro River Watershed Microbial Source). For a summary of the report, please see here.
- Pollution Prevention Activity #2: South County Nutrient Program
Valley Water performed a spatial analysis of South County agricultural parcels to identify farms at high risk for nutrient and pesticide pollution. The prioritization considered a robust collection of attributes, including, but not limited to, predicted nitrate concentrations in shallow groundwater, crop and irrigation type, and soil erosivity. Valley Water presented the analysis to the South County Stormwater Coordination Committee. Valley Water is currently developing follow-up actions to reduce nutrient loading in the Uvas/Llagas Watershed.
Pollution Prevention Activity #3: South County Storm Water Resource Plan
Valley Water is developing a Storm Water Resource Plan (SWRP) in collaboration with stormwater permittees in South County (Gilroy, Morgan Hill, and County of Santa Clara) to identify and prioritize Green Stormwater Infrastructure (GSI) opportunities that could be eligible for funding. The SWRP is a planning document that uses a map-based approach to identify and prioritize local and regional GSI projects that can be implemented to improve local surface water quality through enhanced stormwater management. GSI reduces the quantity and improves the quality of water flowing into our creeks, while also providing other possible benefits, including groundwater infiltration, flood attenuation, aesthetics, reduction in heat islands, and other community benefits.

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.
