Rock Creek GI Project C

DC Water is excited to announce the next green infrastructure (GI) project in the Rock Creek sewershed, Rock Creek Project C!  Rock Creek Project C is currently in the Design Phase. Construction for Rock Creek Project C is anticipated to begin in 2025. Details regarding the project will be coming soon.  

Overview

Rock Creek Project C is part of DC Water's Clean Rivers GI Projects.It is the third green infrastructure (GI) project constructed in the Rock Creek sewershed. The first and second green infrastructure projects,Rock Creek Project A and Rock Creek Project B, were completed in 2018 and 2023, respectively. DC Water’s Clean Rivers Projects will significantly reduce the level of pollution to the District’s waterways produced by the discharge of stormwater runoff and sanitary sewer flows, known as combined sewer overflows (CSOs).

Rock Creek Project C includes the construction of alley permeable pavement and bioretention sites. These practices manage stormwater 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 transpire it as vapor. In addition to managing stormwater, GI contributes to beautifying the streetscape and making it more welcoming for pedestrians, bicyclists and drivers.

Maintenance

To ensure continued performance of GI and the associated reduction of combined sewer overflows, the GI facilities will be maintained regularly.  DC Water is responsible for maintenance of GI facilities. Facility IDs will be placed at each GI facility that DC Water constructs in your neighborhood and you can contact DC Water if you notice trash or other issues in the facilities.
