In New York City, an estimated 20 billion gallons of sewage and polluted stormwater runoff flows into the Hudson River and other waterways each year. New York City recognizes the value of green infrastructure and the Department of Environmental Protection (DEP) has budgeted. 1.5 billion for green infrastructure to reduce combined sewer overflows (CSOs) and improve water quality by 2030. The challenge they face is that as much as 50 per cent of the land is priority areas where CSO’s occur is owned by the private sector and the DEP is running out of places to build bioswales.
Despite the numerous approaches to managing stormwater, green roofs have become a top priority for the DEP and highly regarded by City Councilors. “Green roof investments pay dividends not just for building owners, but for the city and the environment as a whole,” said Manhattan Borough President Gale A. Brewer. Congressman Joe Crowley (D-Queens, the Bronx), Chairman of the House Democratic Caucus says “Our city’s roofs are an untapped resource in reducing stormwater runoff and making our homes more energy efficient”.
