Cobb County Stormwater Management Ordinance (Ch. 50, Art. VIII) requires post-development runoff to match pre-development for 25-year storm. MS4 permit (GAEPD). Water-quality volume treatment on all new development >1 acre disturbance.
Cobb County is a Phase I MS4 community under GAEPD NPDES permit GAR041001. The Post-Development Stormwater Management Ordinance (Code Ch. 50, Art. VIII) requires all new development and significant redevelopment to: treat the first 1.2 inches of runoff (Water Quality Volume) for pollutant removal; detain the 25-year / 24-hour storm to pre-development peak flow; address channel-protection storage; and submit a maintenance agreement for BMPs. Common BMPs include wet ponds, bioretention, sand filters, and enhanced swales. The Cobb County Water System's Stormwater Management Division (770-419-6406) reviews plans alongside Community Development. Illicit discharges to the storm drain system are prohibited under Ch. 50, Art. IV with fines up to $10,000/day. Cobb is in the Chattahoochee River, Sweetwater Creek, and Noonday Creek basins — all are federally listed TMDL watersheds.
Failure to install/maintain BMP: stop-work and $500–$10,000 fine. Illicit discharge: up to $10,000/day per §50. Sediment or oil to storm drain: mandatory cleanup + restoration.
