Mobile regulates stormwater runoff under MCO Ch. 17 and the city MS4 permit, requiring on-site detention, post-construction BMPs, and prohibiting illicit discharges into Mobile Bay tributaries and Three Mile Creek watershed.
Properties disturbing one acre or more must submit a Stormwater Pollution Prevention Plan (SWPPP) to the Mobile Engineering Department before grading. Smaller residential lots still must control runoff onto neighbors. The city's MS4 permit, issued by ADEM, prohibits dumping oil, paint, soap, or yard chemicals into storm drains, all of which discharge untreated into Mobile Bay. Inspectors patrol commercial sites after rain events. Repeat illicit discharges trigger escalating civil penalties and ADEM referral. Low-impact development incentives apply downtown.
First illicit discharge typically draws a written notice and cleanup order; repeat or commercial violations carry fines up to 500 dollars per day plus ADEM enforcement.
