The NYC Stormwater Management Program Plan (the Plan) is the City’s first comprehensive planning effort to target pollution generated in areas served by the municipal separate storm sewer system (MS4) which comprises nearly 40% of the City.
With this Plan, the City will continue to identify sources of stormwater pollution and develop a range of policies and strategies to reduce it, all with the goal of improving and protecting the waters for the generations of New Yorkers to come.
