Our crew is putting the finishing touches on this stream realignment in Annandale, VA. This project included stream restoration, realignment, new sanitary sewer, removal of old asbestos sanitary sewer pipe and a new pedestrian bridge. This was a very effective project using stream restoration techniques to protect infrastructure in a suburban setting just inside the beltway.

Another one in the ground! Thank you to all that helped make our Tenleytown Bioretention a success! We couldn’t have done it without the support of our amazing community partner, Tenleytown Main Street. We had a lovely Ribbon Cutting Ceremony last week with representatives from DDOT, Department of Energy & Environment, PepcoConnect, Tenleytown Main Street, and Ward 3 Councilmember Matt Frumin. This project not only treats over 2,700 gallons of stormwater runoff, but also added traffic and pedestrian safety measures at the intersection. The design and construction was funded by DOEE through an EPA grant, the Ribbon Cutting Ceremony and maintenance training was funded by Pepco and Sustainable Maryland, and the bench was funded by Tenleytown Historical Society. CWP designed the project and Triangle Contracting, LLC constructed it. Thank you all our other supporters, DC Water, DC Office of Planning, Cafe of India, Le Chat Noir Restaurant, and ANC3E.
