An asphalt traffic intersection in Colmar Manor, MD was replaced with PaveDrain heavy-duty permeable pavement, along with an in-situ water level sensor for performance monitoring. This project was undertaken to address the frequent stormwater challenges in the Town of Colmar Manor in Prince George’s County, Maryland.
In the two years since it was installed the system is functioning as a roadway and stormwater BMP without maintenance, representing a commitment to environmental justice in this economically disadvantaged neighborhood. Furthermore, the use of sensors has documented stormwater performance well in excess of expected, suitable for crediting towards - giving extra credit towards - local stormwater compliance.
