The Green Roof at the Reeves Center                                           The Green Roof at One Judiciary Square

Mayor Fenty has expressed great interest in transforming Washington, DC into a sustainable city for the 21st century. Green roofs were one of many sustainable practices the Fenty Administration highlighted as part of the “100 Days and Beyond” plan*.

A green roof is partially or completely covered with vegetation and soil, or a growing medium, planted over a waterproofing membrane. Green roofs support the City’s vision for restoring the Anacostia by reducing storm water runoff. During heavy rains, storm water run-off can overburden the sanitary sewer system and lead to raw sewage overflows to the river. Green roofs absorb rainwater, preventing it from entering the waste water system. In addition, green roofs perform an insulating function which reduces the energy demand of buildings and thus reduces our greenhouse gas emissions.
