DC Water – Potomac River Green Infrastructure Project A

Potomac River Project A is the first Green Infrastructure (GI) project proposed to be constructed in the Potomac River Sewer shed to reduce the level of pollution to the Potomac River produced by the discharge of storm water runoff and sanitary sewer flows, known as combined sewer overflows (CSOs).

Potomac River Project A involves the construction of innovative GI technologies that include bio retention on planter strips and permeable pavement on streets and alleys. These practices will manage storm water by taking advantage of the earth’s natural processes, such as allowing the water to infiltrate into the soil, evaporate into the air or be used by plants which expire it as vapor. In addition to managing storm water, GI will contribute to beautifying the streetscape and making it safer and more welcoming for pedestrians, bicyclists and drivers.

Potomac River Project A is composed of two areas delineated by Calvert Street NW to Whitehaven Parkway and Fortieth Place NW to Wisconsin Avenue NW and Whitehaven Parkway to Reservoir Road NW and Thirty-Fifth Street NW to Thirty-Nine Street NW in the Glover Park and Burleigh neighborhoods of northwest Washington, DC.

The Clean Rivers Project is DC Water’s ongoing program to reduce combined sewer overflows into the District’s waterways – the Anacostia and Potomac Rivers and Rock Creek.  The Project is a massive infrastructure and support program designed to capture and clean water during heavy rainfalls before it ever reaches the DC area’s rivers.

L. S. Caldwell & Associates, Inc. (LSC) was chosen as the Project Compliance Officers to perform various oversight project functions.
