In 2012, the New York City Department of Environmental Protection (DEP) signed a groundbreaking agreement with the New York State Department of Environmental Conservation (DEC) to reduce combined sewer overflows (CSO) using a hybrid green and grey infrastructure approach. By the time of the signing, DEP had already established the Office of Green Infrastructure Task Force to develop standard designs, specifications, and siting procedures for Right-of-way bioswales, launched the Green Infrastructure Grant Program, adopted a new rule for stormwater management in new construction, and built first generation green roofs, blue roofs, bioswales, rain gardens, and other types of green infrastructure across the City's combined sewer areas.
