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 is designed to meet a requirement to manage 1.2” of stormwater runoff from at least 25 impervious acres. This requirement will be achieved through the construction and implementation of permeable pavement within alleyways. Rock Creek Project C GI facilities will be located in the public right-of-way in eight project areas throughout the Rock Creek sewershed of Ward 4 (see image below showing the project areas and the corresponding factsheets that provide additional information regarding the proposed sites). Project areas were selected for their feasibility of design and construction, cost-effective implementation, and ability to meet the required stormwater volume capture. GI facilities in this project will not be located on Federal properties or sensitive historical or archeological sites.
Rock Creek Project C includes the construction of alley permeable pavement sites. The main image above shows an example of previously constructed alley permeable pavement. Permeable pavement allows stormwater runoff to infiltrate through the pavement and into the ground and slowly releases any excess stormwater runoff into the combined sewer system.

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.
