DEC and DEP Announce Groundbreaking Agreement To Reduce Combined Sewer Overflows Using Green Infrastructure in New York City

$2.4 Billion in Green Infrastructure and $1.4 Billion in Gray Infrastructure to Target the City’s Most Impaired Waterbodies; Total Savings of $1.4 Billion from Grey Infrastructure Substitution Projects and an additional $2 Billion in Deferred Costs

The New York State Department of Environmental Conservation and New York City Department of Environmental Protection today announced an agreement on an enforcement Order to improve the overall water quality in New York Harbor waters. Under this agreement, the City will invest approximately $187 million over the next three years and an estimated $2.4 billion of public and private funding over the next 18 years to install green infrastructure technologies to manage stormwater before it enters the City’s combined sewer system. The City maintains the flexibility to prioritize green investments in areas of the City that will benefit most from the resulting reductions in combined sewer overflows.

“DEC and New York City worked collaboratively to develop an innovative and cost-saving approach to water quality problems in New York Harbor,” DEC Commissioner Joe Martens said. “New York City’s use of green infrastructure to achieve water quality goals at lower cost to ratepayers should serve as a model for other large, urban communities in New York State and the nation. Green infrastructure beautifies the urban landscape, a benefit long sought by environmental justice stakeholders.”
