  • 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. <br />
  • * Projects total. This is the first 6 <br />
  • Good morning, I’m Andrew Schock from the Conservation Fund. Thank you all for inviting me to talk about collaboration in Green Infrastructure development – we are off to a good start by having all of you in the room at once! First let me tell you a little bit about The Conservation Fund. <br />
  • We facilitate real estate transaction for the Cities, States and Federal governments – In Atlanta we have helped to protect over 50% of the non-beltline greenspace since 2005 – with more on the way <br />
  • But this is only successful because of the collaborative partnerships <br />

  • Department of Watershed Management Promoting Sustainability • Goal of green infrastructure - mimic the natural hydrologic function – preserving conservation areas – reducing impervious surfaces – installing aesthetically-pleasing structural measures such as • green roofs, vegetated swales, permeable pavement, infiltration planters, cisterns, and rain gardens. • An alternative approach to managing stormwater runoff • Decreasing energy consumption • Waste to energy program • Enhancing aesthetics and public access/use
  • Department of Watershed Management 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
