Napa County Stormwater Pollution Prevention Program

The Napa Countywide Stormwater Pollution Prevention Program (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.
