Lot 12 Bioswale

Location: WSU Parking Lot 12 
Client: Wayne State University

Goals: Stormwater Management, Wildlife Habitat, Beautification

This site is DBN's first bioswale project, established in partnership with the Rain Gardens to the Rescue program and the WSU Office of Campus Sustainability. It was first planted in Fall 2017 and has since developed into a mature mix of native plant species specifically selected to tolerate varying moisture, heavy clay soils, road salt, and other common pollutants.  

Water from the parking lot is graded toward the center where the plants intercept, retain and filter the stormwater that flows into the swale. The site has since been studied in several research projects by the College of Engineering, Geology, and Biological Sciences departments.



3,243 sq. ft. of bio-retention and native wildlife habitat

54,014.4 sq. ft. impervious surface drainage area

33,650.97 gallons of water per inch of rain managed
