VENTURA COUNTY STORMWATER PROGRAM

Stormwater Pollution Prevention

The County Stormwater Program oversees the areas of unincorporated Ventura County for the Federally-mandated stormwater management program. The Program implements requirements and ensures compliance under Ventura Municipal Stormwater Permit Order No. R4-2010-0108. The Program addresses activities including the development of project conditioning, construction site inspections, illicit discharge investigation and enforcement, business compliance inspection, public outreach/education, and County employee training.

This page has Stormwater Training Materials, information about Illicit Discharge, the Technical Guidance Manual for Stormwater Quality Control Measures, Total Maximum Daily Load (TMDL) information, and more!

Illicit Discharge Reporting Hotline

Question: What is an Illicit Discharge?

Answer: An illicit discharge is any activity or event which results in a release, leak, flow, escape or the placement of any material other than rainwater (including liquids or solids) into the storm drain system. Certain exemptions exist for emergency firefighting activities, irrigation runoff, individual residential car washing, or discharges covered by a separate National Pollutant Discharge Elimination System (NPDES) permit.

  • To report an illicit discharge to the storm drain within areas of unincorporated Ventura County, please  email, call (805) 650-4064, or submit a report online (by going to the “Watershed Protection” tab and then “Illicit Discharges or Connections”).
  • To report sewage, wastewater or hazardous material discharges, please contact the Ventura County Environmental Health Division at (805) 654-2813. For after hours on-call emergency response, please call (805) 320-6244.
  • To report an illicit discharge within an incorporated city boundary, please click here for contact information for individual cities.

2011 Update to Ventura Countywide Technical Guidance Manual for Stormwater Quality Control Measures

The 2011 Update to the Ventura County Technical Guidance Manual for Stormwater Quality Control Measures was approved by the Executive Officer of the Regional Water Quality Control Board in July 2011.

The new land development requirements became effective on October 11, 2011. New Development and Redevelopment projects, which applications have not been deemed complete for processing before the effective date, will be subject to new rules if they meet Applicability Criteria defined by the Regional Water Quality Control Board.

For more information on Applicability Criteria, refer to County Stormwater Program’s Policies section here.

For more information on the how the effective date applies to your project see pages 1-8 of the updated Manual available at http://www.vcstormwater.org/technicalguidancemanual.html.

If your project, located within the County Unincorporated area, is subject to new land development requirements for Post-Construction Stormwater Management Plan (PCSMP), refer to the following websites for additional information and forms:
