Bulloch County, GA Environmental Rules: Stormwater Management (2026)

5-68, part of the county stormwater control ordinance adopted April 4, 2023, requires that development, excavation, construction or land-disturbing activity in the unincorporated area comply with the article's standards, be preceded by an approved stormwater management and drainage plan (SDP) and permit, and be maintained afterward under the design and maintenance standards of Division 2. 6 acres of impervious surface, utility installations outside easements, agricultural or silvicultural projects on land zoned for those uses, and state projects. 5-70, the SDP must be filed with the planning and development department and prepared under a Georgia-registered professional engineer, including a site location map, topographic contours, a hydrologic analysis comparing pre- and post-development runoff for storms up to the 100-year event, and delineation of the 100-year floodplain from FEMA maps.

5-83 require detention or retention for any development that raises peak runoff by more than one cubic foot per second in a ten-year, 24-hour storm, with release rates capped at the pre-development 25-year peak, and drainage systems sized to carry a 25-year storm, or a 100-year storm for major drainage canals. A permit lapses if the approved activity is not started within 12 months.
