Rock Creek Green Infrastructure Project A

Thank You!

Thank you for helping the Rock Creek Project A during the design of green infrastructure (GI) practices and selection of sites to receive GI practices! Your participation during community meetings, local ANC meetings, and written and online surveys was very important! Find GI practices constructed near you within the Rock Creek Project A area by clicking on the interactive map below:


Rock Creek Project A was the first GI project to be constructed in the Rock Creek Sewershed to reduce the level of pollution to Rock Creek produced by the discharge of stormwater runoff and sanitary sewer flows, known as combined sewer overflows (CSOs).

Rock Creek Project A involved the construction of innovative GI technologies that include bioretention on planter strips and curb extensions, permeable pavement on streets and alleys, and downspout disconnection (including rain barrels). 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 that expire it as vapor. In addition to managing stormwater, GI contributes to beautifying the streetscape and making it safer and more welcoming for pedestrians, bicyclists, and drivers.

Construction Start August 2017
Construction Finish October 2018
Monitoring 2019 - 2020

* Note: From 2019 to 2020, the GI practices will be monitored and assessed to evaluate performance.
