NYC Green Infrastructure Program

New York City’s Green Infrastructure Program is a multiagency effort led by the Department of Environmental Protection. DEP and agency partners design, construct and maintain a variety of sustainable green infrastructure practices such as green roofs, rain gardens, and Right-of-way Bioswales on City owned property such as streets, sidewalks, schools, and public housing. Green infrastructure promotes the natural movement of water by collecting and managing stormwater runoff from streets, sidewalks, parking lots and rooftops and directing it to engineered systems that typically feature soils, stones, and vegetation. This process prevents stormwater runoff from entering the City’s sewer systems. DEP is currently building green infrastructure in compliance with NYS Department of Environmental Conservation (DEC) requirements to reduce combined sewer overflow (CSO) discharges into New York City’s waterbodies. DEP is also exploring the use of green infrastructure to reduce polluted runoff from reaching waterbodies through the separate storm sewer system. In addition to the benefits to water quality, green infrastructure also beautifies City streets and neighborhoods while improving air quality.
