Implementing Green Infrastructure:
Atlanta’s Post-Development Stormwater Management Ordinance
The Department of Watershed Management has recently updated the Post-Development Stormwater Management Ordinance to promote the use of Green Infrastructure on new and redevelopment projects in the City. Green infrastructure uses natural hydrologic features to manage water and provide environmental and community benefits. On development sites, Green Infrastructure includes engineered practices that are designed to mimic natural hydrology by infiltrating stormwater runoff into the ground, evapotranspiration (uptake of water by plants) in landscaped areas, or capturing and reusing the runoff through rainwater harvesting techniques. For more information on green infrastructure or the revised stormwater management requirements, see the resources below.
