As part of an intense effort to clean up the Anacostia River and the Chesapeake Bay region, the Maryland Department of Environment will soon enforce new policies to increase the treatment of impervious areas. The University of Maryland’s College Park campus needs to identify potential projects in order to meet the pending stormwater regulations as part of the new municipal separate storm sewer systems (MS4) permit for UM-CP. This thesis investigates retrofits a poorly maintained stormwater pond that has maintained itself as a wetland. The 4.89-acre site is located in the north part of campus is a part of the Anacostia watershed and includes the pond, two parking lots, and a wet swale. This thesis proposes a stormwater retrofit that includes various state acceptable BMPs including: a constructed wetland, mirco-bioretentions, pervious concrete, and a bio-swale. The BMPs forms a treatment train that reducing runoff by 7%, capturing and treating 113% of a one-year storm of 2.63 inches. This redesign that would provide a range of environmental, recreational, and educational services. While the proposal is site-specific, the model can be adaptable for retrofitting centralized stormwater facilities and by other college campuses within the Chesapeake Bay watershed.
