In September 2010, New York City released the NYC Green Infrastructure Plan which presents an alternative approach to improving water quality that integrates “green infrastructure,” such as swales and green roofs, with investments to optimize the existing system and to build targeted, cost-effective “grey” or traditional infrastructure.

Public Outreach

On June 28, 2010, DEP held a city-wide meeting to present and review the analysis and incorporate the ideas of the public into the NYC Green Infrastructure Plan.  During this meeting, DEP presented a general overview of the Plan and then the attendees broke into three groups – concerning two watersheds each – in which the public offered general and targeted ideas about green infrastructure in New York City.

Throughout the implementation of the NYC Green Infrastructure Plan the City will continue to engage the public and solicit ideas to improve and expand green infrastructure opportunities.
