  • 12. 122013 3rd Quarter 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
