Green Infrastructure

When it rains, green infrastructure collects and manages the rain water or “stormwater” that falls on our city’s streets and sidewalks. Green Infrastructure prevents stormwater from entering the City’s sewer system, which helps to improve the health of local waterways.

We have successfully built thousands of Green Infrastructure installations, like Rain Gardens, across New York City.

Private Property Stormwater Incentives

We provide financial incentives for installing green infrastructure, or stormwater source controls, on private property in New York City. These programs help to cover up to 100% of the costs of designing and constructing green infrastructure practices.

Green Infrastructure Plans and Reports

Green Infrastructure Standards and Specifications

DEP has developed design guidelines, standards and specifications for:

  • green infrastructure built in city streets and sidewalks (right-of-way (ROW))
  • green infrastructure built within the property line of a City-owned site such as parklands and schools (public on-site)

These design standards and procedures are used by engineers, architects, landscape architects, and other city agencies to streamline the development of contract plans and drawings, and reduce the timeline and costs associated with design and approval processes. For access to previous versions of the Standards for Green Infrastructure, please contact gioutreach@dep.nyc.gov.
