Roswell, GA Environmental Rules: Stormwater Management (2026)

2, Post-Development Stormwater Management) states its purpose as controlling the adverse effects of increased post-development runoff and nonpoint source pollution, aiming to keep new development's post-development hydrology as close as practicable to pre-development conditions. 2 sets the numeric triggers: the ordinance applies to new development creating 5,000 square feet or more of impervious cover, or one acre or more of land-disturbing activity of any kind, and to redevelopment meeting the same thresholds, plus any project the engineering division manager or public works director designates a 'hotspot land use' regardless of size.

Non-residential projects adding between 1,000 and 5,000 square feet of impervious cover must still provide water quality protection using approved low-impact-development methods. Four categories are exempt outright: individual single-family or duplex lots not part of a subdivision, additions to existing single-family or duplex homes, agricultural or silvicultural activity on properly zoned land, and repairs to existing stormwater facilities ordered by the public works director. 4 ties technical design to 'the latest edition of the Georgia Stormwater Management Manual' plus any local procedures the department adopts.

7: a written notice of violation must state the violation, the site, required remedial measures and a completion date, and the recipient has 30 days to appeal (24 hours where the violation endangers public health or safety). 3, the city's general penalty section, which caps fines at $2,000, imprisonment at 180 days, and community service at 180 days, with each day of continued violation a separate offense.
