Atlanta addresses urban heat through tree-canopy preservation, ATL2050 cool-corridor goals, and Beltline green infrastructure rather than a single ordinance, layering tree, stormwater, and zoning rules.
Atlanta has one of the highest urban tree canopies among large US cities (~46%), and Ch. 158 of the City Code requires recompense for tree loss to maintain that canopy. The ATL2050 Comprehensive Plan includes heat-island mitigation through cool corridors, shade trees, and permeable pavements along the Beltline and MARTA station areas. The Department of City Planning's Sustainability Division coordinates with Watershed Management on green infrastructure that reduces both runoff and surface temperatures. Heat-vulnerability mapping informs capital prioritization, especially in historically underinvested neighborhoods on the city's south and west sides where canopy is thinner.
Mitigation goals are programmatic; enforcement happens indirectly through tree-protection penalties, zoning landscape requirements, and stormwater compliance rather than a heat-specific citation.
