Thousand Oaks requires erosion and sediment control measures for all construction and grading activities. Properties on hillsides face stricter requirements. Stormwater pollution prevention plans (SWPPPs) are required for projects disturbing one or more acres.
TOMC Chapter 9 and the city's grading ordinance require erosion and sediment control on all construction sites. Best management practices include silt fences, fiber rolls, construction entrances, and stabilized slopes. Projects disturbing one or more acres must prepare and implement a Stormwater Pollution Prevention Plan (SWPPP) under the state Construction General Permit. Thousand Oaks has significant hillside areas, particularly bordering the Santa Monica Mountains, where erosion risk is elevated. Hillside development requires geotechnical studies and enhanced erosion control measures. The city inspects construction sites during the rainy season (October through April) for BMP compliance. Exposed soil must be stabilized or covered before rain events. Post-fire conditions in Woolsey Fire burn areas created ongoing erosion concerns that continue to require monitoring.
Erosion control failures can result in stop-work orders and fines. SWPPP violations under the state permit carry penalties up to $10,000 per day. Sediment discharge to waterways triggers additional regulatory action.
