NYCDEP Completes Green Infrastructure Projects in Brooklyn

The Neighborhood-Scale Demonstration Project Will Beautify the Neighborhood and Provide Valuable Data about the Reduction in Combined Sewer Overflows from Green Infrastructure

Bioswales resemble standard street tree pits but they are significantly larger, have curb cuts that allow stormwater to enter and exit, and have been designed in a way that will allow each one to manage approximately 2,244 gallons during a storm.

Thus far, DEP has installed 119 bioswales city-wide, hundreds more will be completed by the end of the year, and thousands will be added over the next five years.

Taken together, installations in Newtown Creek, Jamaica Bay, and Hutchinson River tributary areas will collect more than 7 million gallons of stormwater a year.

(June 4, 2013 – NEW YORK, NY) – New York City Department of Environmental Protection (DEP) Commissioner Carter Strickland today joined New York State Department of Environmental Conservation (DEC) Regional Director Venetia Lannon to announce that the recently completed installation of green infrastructure in the Bushwick section of Brooklyn will prevent more than one million gallons of stormwater from reaching the combined sewer system each year and thereby improve the health and cleanliness of the water in Newtown Creek and New York harbor.

As part of the $335,000 project, DEP built 19 bioswales, which are curbside gardens that are specifically designed to collect and absorb stormwater from the street and sidewalk, along Grove Street between Goodwin Place and Wilson Avenue. The bioswales were installed in a defined area where the sewers drains to a single pipe in which flow meters were installed to measure the amount of stormwater both before, and after, construction to quantify the reduction in stormwater runoff. The Neighborhood Demonstration Area is the third to be completed pursuant to a March 2012 Modified Consent Order with DEC, which formalized the City’s inclusion of green infrastructure as an important component of its plan to reduce combined sewer overflows (CSOs) into local waterways and improve the ecological health and cleanliness of New York City harbor water.

“This is our third neighborhood pilot project and these 19 bioswales are adding to our network of green infrastructure, as envisioned in the NYC Green Infrastructure Plan, that will improve the health and cleanliness of Newtown Creek and other local waterbodies,” said Commissioner Strickland. “These green infrastructure projects also green the neighborhood, provide shade in the summertime, clean the air, and make the streets a more enjoyable and welcoming place.

“NYSDEC continues to enthusiastically support Green Infrastructure projects like this one at Newtown Creek which is consistent with Governor Cuomo’s NYS 2100 Commission,” said NYS Department of Environmental Conservation Commissioner Joe Martens. “Converting impervious surfaces within the city’s neighborhoods to a more natural and absorbent landscape integrates water quality and ecological benefits for cleaner waterways and a more sustainable community.”
