Project location: Annapolis, MD

Problem:  The watershed of Cabin Branch Stream contains the Annapolis Mall and associated commercial areas.  Due to a high concentration of impervious surfaces in this area, water quality in the stream has been deteriorating.

Project location: Annapolis, MD

Problem: Parking lots typically contain significant amounts of impervious cover, and they can be a major source of pollutants to nearby streams. The parking lot of Blackwall Hitch, a seafood restaurant in downtown Annapolis, drains directly into Spa Creek, a major tributary of the Severn River.  Prior to this project, pollutant-laden rainwater flowed from the parking area and surrounding streets into the Creek.
