Long Island Sound Ecosystems Grant Program

Deadline for Submission December 16, 2025, at 11:59 PM

The Connecticut Department of Energy and Environmental Protection is pleased to announce the new Long Island Sound Ecosystems Grant Program. This funding is intended to support the planning and implementation of projects focused on coastal habitat restoration and green stormwater infrastructure across the state. There are two primary goals of the program: 1) to promote large-scale habitat restoration and enhance restoration planning, while also helping coastal communities and ecosystems adapt to changing environmental conditions; and 2) to further promote the application of green stormwater infrastructure techniques to reduce nonpoint source pollution, improving water resource quality.

There is approximately $7 million available; no match is required. This grant program is made possible by financial support provided by the Long Island Sound Partnership from the U.S. Environmental Protection Agency (EPA).
