New York City Green Infrastructure Grant Program

New York City’s Green Infrastructure Program is a multi-agency effort led by the Department of Environmental Protection (DEP). The NYC DEP offers a green infrastructure grant program for private property owners in combined sewer areas of New York City. The program provides funding for green infrastructure projects that manage the first inch of rainfall, including blue roofs, rain gardens, green roofs, porous pavement and rainwater harvesting. Private property owners in combined sewer areas are eligible for the grants of up to $5 million. In order to ensure that the green infrastructure is well-maintained, grantees must sign a covenant that requires twenty years of maintenance.  Due to this covenant, the grant money continues to have a long-term impact long after the funds are disbursed.

There is no submission deadline for the grant program - grant applications can be submitted anytime throughout the year. DEP hosts ongoing workshops to explain the eligibility requirements of the program and guide users through the online application.

Also grantees are encouraged, but not required, to incorporate the following additional benefits into their green infrastructure project:

- Have secured matching funds/in-kind contributions
- Provide a monitoring plan
- Provide letters of support from community stakeholders
- Allow for education and/or public access
- Support workforce development
- Advance the ultimate sustainability goals of the Green Infrastructure Plan and PlaNYC


Since its introduction in 2011, the Grant Program has sought to strengthen public-private partnerships and public engagement in regards to the design, construction and maintenance of green infrastructure on private property. To date, the Grant Program has committed more than $13 million to 33 private property owners to build green infrastructure projects in combined sewer areas. 

DEP is currently building green infrastructure in compliance with NYS Department of Environmental Conservation (DEC) requirements to reduce combined sewer overflow (CSO) discharges into New York City’s waterbodies. DEP is also exploring the use of green infrastructure to reduce polluted runoff from reaching waterbodies through the separate storm sewer system.
