Miami FAQ
What erosion controls are needed for waterfront construction?
Waterfront construction near Biscayne Bay requires turbidity barriers in addition to standard BMPs like silt fences and inlet protection due to the sensitivity of the marine environment.
When must erosion controls be installed?
Erosion and sediment controls must be installed before any land-disturbing activity begins and maintained throughout construction until permanent stabilization.
North Miami FAQ
What erosion controls are required on construction sites in North Miami?
All construction sites must install silt fences, inlet protection on nearby storm drains, and stabilized construction entrances. Projects over one acre need a full SWPPP under the FDEP NPDES construction permit with regular inspections.
How often must erosion controls be inspected?
BMPs must be inspected at least every seven days and within 24 hours of any rainfall event of 0.5 inches or more. Damaged or ineffective controls must be repaired or replaced immediately.
What happens if sediment enters the storm drain from my construction site?
You must remove the sediment immediately. Sediment discharge to the stormwater system may result in stop-work orders, city Code Enforcement fines, and FDEP penalties up to $10,000 per day. Discharge reaching Biscayne Bay may also trigger Miami-Dade DERM enforcement.
