Green Infrastructure Pilot Program

Client: Metropolitan St. Louis Sewer District​
Owner: Metropolitan St. Louis Sewer District​
Year: 2015

M3 Engineering was selected to perform a Green Infrastructure Pilot Program for the Metropolitan St. Louis Sewer District. The scope included site visiting locations within the Bissell Watershed and leading a team for the design of 10 green infrastructure (GI) BMPs that will help reduce Combined Sewer Overflows (CSOs) to the Mississippi River through a reduction in stormwater runoff. The GI BMPs under consideration included: bioretention; pervious parking/alleys/sidewalks; rain barrels, wet ponds; wetlands; dry swales; surface sand filters; organic filters and the combination of several of these techniques into neighborhood-scale stormwater retrofits. As part of their Long Term Control Plan in St. Louis, MSD will spend $100M to construct GI and promote low impact development (LID) in combined watersheds that discharge to the Mississippi River. MSD's goal is to use this Green Infrastructure pilot project to explore how to best develop the approach for the future of green infrastructure in St. Louis.
