Stonecrest, GA Environmental Rules: Stormwater Management (2026)

Under Sec. 14-552 of the Stonecrest Code, the City requires a stormwater management plan for any land development that increases the peak runoff rate by more than one cubic foot per second in a ten-year frequency storm, adds 5,000 square feet or more of new impervious cover, disturbs an acre or more, or creates a stormwater hotspot as determined by the Community Development Director. Individual single-family and duplex lots outside a subdivision are exempt unless they trip one of these thresholds. Plans must be stamped by a Georgia-licensed professional engineer and follow the design criteria and rainfall intensities in the Georgia Stormwater Management Manual, covering the drainage system's storm capacity and stream-channel protection standards.

Detention facilities require fencing and a recorded inspection and maintenance agreement that binds future owners, and joint facilities serving more than one property need Zoning Board of Appeals approval. The Director performs periodic inspections, and owners must keep maintenance records. If the responsible party will not maintain a facility, Sec. 14-556(g) lets the Director issue 30 days' written notice, or just 24 hours if the failure is an immediate danger to public health or safety, then have the City perform the repair itself and place the cost as a lien on the property, collectible on the ad valorem tax bill.
