An Erosion and Sediment Control Plan (ESCP) is required for construction projects in LA. Projects disturbing 1+ acres must file a state SWPPP with the Regional Water Quality Control Board. The LID ordinance requires BMPs to prevent erosion during and after construction. Hillside grading is subject to additional erosion controls under LAMC Chapter IX.
Los Angeles mandates erosion and sediment control for construction sites and land-disturbing activities. Grading permits typically require an erosion control plan. Best management practices include silt fencing, straw wattles, erosion control blankets, stabilized construction entrances, and sediment basins. Disturbed areas must be stabilized within a set timeframe. Inspections required during construction. Permanent stabilization through vegetation or hardscape required upon completion. Violations can result in stop-work orders.
Missing erosion controls: stop-work order and fines $250 to $2,500. Sediment discharge to waterways: fines $1,000 to $25,000 per day. Failure to stabilize: daily fines until corrected.
