This project supports Valley Water’s continued participation in the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) and South County stormwater programs. These programs enable Valley Water to reduce stormwater pollution through technical support and regional leadership. In addition, this project supports stormwater pollution prevention activities in South County Watersheds and green stormwater infrastructure (GSI). GSI allows rainwater runoff from roads, parking lots and other impervious surfaces to soak into the ground and be filtered by soil rather than discharge into storm drains that transport the water to creeks.
The project allows Valley Water to participate in the regulatory development process related to stormwater by participating in stormwater permit re-issuance and providing review, analysis and comments on various water quality regulatory efforts. This project also allows Valley Water to collaborate with local agencies on public education and outreach activities to help prevent urban runoff pollution at the source.
Multi-benefit projects, such as green stormwater infrastructure, are important strategies to address water quality. Green infrastructure uses plants to soak water into the ground, which slows down, spreads and helps absorb rainwater instead of having it go down a storm drain. This improves water quality, can increase groundwater supplies and reduces peak flows to a creek.
Trash capture devices
Two trash booms are currently deployed in Lower Silver Creek and Thompson Creek.
Trash booms managed by the City of Palo Alto in Matadero and Adobe Creeks were removed in December for the winter season as required by the joint agreement and have been re-deployed.
Valley Water staff regularly inspect these trash booms while deployed, and trash is removed as needed.
Municipal stormwater compliance program
Valley Water is maintaining the program as required by the Municipal Regional Stormwater National Pollutant Discharge Elimination System (NPDES) Permit.
Valley Water maintains North County partnerships through participation in the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP). Valley Water staff chairs the SCVURPPP Management Committee.
Valley Water participates in various regional stormwater workgroups in cooperation with SCVURPPP and other countywide stormwater organizations.
Valley Water is maintaining South County partnerships by participating in the South County Stormwater Coordination Committee. The committee includes representatives from Valley Water, the County and the cities of Gilroy and Morgan Hill. The committee meets regularly to discuss pollution prevention, stormwater permit compliance and other relevant issues.
Valley Water serves on California Stormwater Quality Association (CASQA) workgroups.

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.
