Green Infrastructure Grant Program


We offer green roof retrofit funding for private property owners in New York City. The goal is to incentivize private property owners to retrofit their roofs with green roofs to manage stormwater runoff. For general information, please visit Green Infrastructure.

Grant Application

We accept applications on a rolling basis. Private property owners interested in applying must download and complete the Pre-Application Form and submit it to gigrantprogram@dep.nyc.gov. Application materials will be provided to potential grantees once a pre-application meeting between the private property owner and DEP is held.

Note: We are no longer accepting applications through the online portal.
