Irvine requires erosion and sediment control for all construction activities under its Grading Code (Title 5, Division 10). Sites disturbing one acre or more must obtain coverage under the state Construction General Permit. The city enforces year-round BMP requirements with enhanced controls during the rainy season. Required measures include silt fences, fiber rolls, sediment basins, and stabilized construction entrances.
Irvine 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.
