B2: Interagency Urban Runoff Program

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.


  • Uses partnerships with municipalities and local agencies to reduce contaminants and improve surface water quality in our streams, reservoirs, lakes and wetlands
  • Maintains District compliance with Regional Water Quality Control Board and National Pollutant Discharge Elimination System (NPDES) permits
  • Allows continued participation in SCVURPPP and South County urban runoff programs
  • Promotes stormwater pollution prevention through public outreach

Project Status

(As of September 2017

  • The project is on schedule and within budget
  • The Thompson Creek boom was reinstalled in June. The Lower Silver Creek boom is in the process of being reinstalled after sediment build up was removed. 2 booms managed by the City of Palo Alto were reinstalled in April 2017 
  • Maintained North County partnerships via the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP)  
  • Submitted annual report to the Regional Board 
  • Co-leading Bay Area wide trash committee and participated in developing a receiving water trash monitoring program plan which was submitted to the Regional Board on July 1, 2017 with monitoring to begin in the fall 
  • In December 2016, the District on behalf of SCVURPPP was awarded a Proposition 1 grant to develop a Storm Water Resource Plan for the Santa Clara Basin. Work has begun on the grant,  the District, in addition to managing the grant, participates on the Technical Advisory Committee.
  • Maintained South County partnerships by participating in the South County Stormwater Coordination Committee
  • 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 is being developed. (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.



 Key Performance Indicators

  1. Install at least 2 and operate 4 trash capture devices at stormwater outfalls in Santa Clara County. 
  2. Maintain partnerships with cities and County to address surface water quality improvements. 
  3. Support 5 pollution prevention activities to improve surface water quality in Santa Clara County, either independently or collaboratively with south county organizations.
