Napa Countywide Stormwater Pollution Prevention Program (NCSPPP)
The NCSPPP is a joint effort of the County of Napa, cities of American Canyon, Napa, St. Helena and Calistoga, and the Town of Yountville to:
- Prevent stormwater pollution
- Protect and enhance water quality in creeks and wetlands
- Preserve beneficial uses of local waterways
- Comply with State and federal regulations
Though the entities of the NCSPPP carry out their own individual stormwater pollution prevention programs, the NCSPPP provides for the coordination and consistency of approaches between the individual participants and documents their efforts in annual reports.
How the NCSPPP is Funded
The NCSPPP is funded by the member agencies and is administered by the Napa County Flood Control and Water Conservation District’s Stormwater Program Manager.
The purpose of this website is to provide solutions for residents and businesses to help control water pollution. We hope this information helps you join our effort to eliminate stormwater pollution in Napa County.
