Most of the rain that falls on walkways and parking lots surrounding Woods Hall is collected by our storm drain systems. While storm drains help to remove stormwater from the site, it has the negative effect on the hydrology of the Chesapeake Bay. The Woods Hall Rain Garden will collect and slow down stormwater flows preventing localized and downstream flooding. Improperly managed runoff during storm events leads to erosion in streambeds and carries harmful pollutants such as oil, sediment, trash, and pet waste. This rain garden also serves to reduce and prevent these types of harmful pollutants from entering into the storm drains. with an average annual precipitation of 42 inches, this rain garden is capturing, infiltrating and reducing the temperature of over 200,000 gallons of rainwater that would otherwise enter from the Anacostia River and then into the Chesapeake Bay.
The Woods Hall Rain Garden was completed in the spring of 2013 in collaboration with public and private partners. In particular, donated materials from Aggregate Industries, major funding support through the Maryland Department of Natural Resources and implementation efforts through the Anacostia Watershed Society in partnership with the University of Maryland made this project possible.
This project also converted
2,495 square feet of lawn into 2,400 square feet of BayScape which will provide habitat for butterflies such as the Baltimore Checkerspot (the official butterfly of the State of Maryland) and other small wildlife.
