Project

Rock Creek Project A is 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 involves 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 will 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 expire it as vapor. In addition to managing stormwater, GI will contribute to beautifying the streetscape and making it safer and more welcoming for pedestrians, bicyclists and drivers.
