Making Detroit’s GSI Count

Making Detroit’s Green Stormwater Infrastructure Count

Detroit faces significant challenges from unmanaged stormwater, including surface flooding and combined sewer overflows (CSOs). The increased rainfall volumes and intensity expected with climate change will only add to this risk. Therefore, stormwater management that can address increased rainfall, reduce downstream pollution, and support healthy communities will play a critical role in the future of Detroit and the surrounding region.

In this report, The Nature Conservancy in Michigan examines 1) the ongoing needs for stormwater management in Detroit, 2) the opportunity to leverage stormwater management into broader impact, 3) the approaches and perceptions of stormwater management designers, and 4) the costs and benefits of a suite of existing stormwater management projects.
