Southeast Atlanta Green Infrastructure Initiative
Background
• Homes built in historic stream channels; low lying areas
where stormwater naturally drain
Stream channels were piped; floodplains still exist due to
pipe overflows from capacity limitations
Combined sewer area out of conveyance capacity
• Limited capacity often exceeded by high rainfall events
• Stormwater runoff exacerbated by higher amounts of
impervious cover running across hard surfaces at greater
velocities
• Over time, systems cannot accommodate developments
Partial improvements made, leaving other problems
Typical solutions can be disruptive, cost prohibitive

The Problem! Homes built in what used to be the historical stream channels. Capacity limitations in the system so the system can’t handle strong, flashy storm events. DWM prepared a integrated model that simulates the surface conditions based on what the combined system capacity.
