County Stormwater Program is a part of the Ventura Countywide Stormwater Quality Management Program (VCSQMP) including ten incorporated cities in the Ventura County and Ventura County Watershed Protection District. The VCSQMP is managed through Management Committee and six subcommittees: Construction, Public Outreach, Public Agency Activities, Land Development, Business Outreach and Illicit Discharge, and Capital Improvement Projects. This is a very comprehensive program as can be expressed by its Mission Statement:

Enhance, protect and preserve water quality in Ventura County water bodies using proactive and innovative ideas for preservation of biodiversity, ecological viability and human health.  Works as a Countywide team with public agencies, private enterprise, the environmental community and the general public to locally implement the Clean Water Act requirements, balancing the actions taken with social and economic constraints.
