Phoenix requires erosion control plans as part of grading and drainage permits under City Code Chapter 32A. The Stormwater Policies and Standards Manual specifies erosion control BMPs. Development in the FH (Flood Hazard and Erosion Management) District under Zoning Section 657 faces additional restrictions to preserve watercourses.
Phoenix 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.
