Construction projects in unincorporated Ventura County must implement erosion control BMPs. Projects disturbing 1 acre or more require a SWPPP under the state Construction General Permit. Heightened requirements apply during the rainy season.
All construction disturbing soil must use erosion control Best Management Practices (BMPs) including silt fences, fiber rolls, and stabilized entrances. Projects over 1 acre require a Stormwater Pollution Prevention Plan (SWPPP). Grading permits from Building & Safety include erosion control requirements. The rainy season (October 1 - April 15) has heightened BMP requirements. The Ventura County Watershed Protection District oversees stormwater compliance.
Failure to implement erosion controls may result in stop-work orders and fines. The Regional Water Quality Control Board can impose penalties up to $10,000/day for discharges. Contact Watershed Protection at (805) 654-2001.
