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

Chapter 2-6, Article V exists to control the adverse impacts of stormwater runoff and protect water resources, per § 2-6-81. Under § 2-6-85, no final subdivision plat is approved and no building permit issues until the public works department reviews and approves a stormwater management plan, except for agricultural land management, additions to existing single-family detached homes, developments of four-tenths of an acre or less, and construction of a single-family personal residence. Plans must be prepared and certified by a registered professional engineer or land surveyor and reviewed within five business days of submission under § 2-6-101.

Design criteria in § 2-6-104 require controlled release that prevents more than a 10 percent increase in pre-development runoff, or one cubic foot per second, whichever is greater, for a ten-year storm, with drainage systems sized for a fifty-year, 24-hour storm. 5:1 need at least four feet of permanent fencing. A performance bond covering the estimated construction cost is required before a building permit or plat approval under § 2-6-116, and the county assumes maintenance of single-family subdivision facilities one year after the bond is released, per § 2-6-119. The board of adjustments and appeals hears variance and waiver requests under § 2-6-86.
