The mission of the Stormwater Management Program is the management of the surface water resources of unincorporated Fulton County. This includes compliance with State and Federal regulations.

Fulton County has several organizational units that provide stormwater services to the citizens of Fulton County. The primary functions performed by this structure include administration, maintenance, operations, regulation and enforcement. These services are provided for areas in unincorporated Fulton County only.

The Transportation Division has the responsibility for operation and maintenance of the stormwater infrastructure systems within the right-of-way in unincorporated Fulton County. The overall coordination of the SWMP, which includes the NPDES MS4 Phase I Permit requirements, is the responsibility of Environmental Compliance Unit.

Illicit Discharge Detection and Elimination

Illicit discharges to our waterways occur due to illegal connections to our storm drain system from residential or commercial areas.  These connections may be intentional or they could be unknown to the property owner.  Failing septic systems, illegal dumping practices, and improper disposal of sewage (such as from boating or camping) can also be considered illicit discharges. 

Our Illicit Discharge Detection and Elimination (IDDE) program is designed to educate citizens and County employees to identify and report illicit discharges that are contaminating our water resources.  Learn more about how you can help protect water quality in your community by reporting suspicious substances in your local waterways.
