WORKING TOGETHER,
TOMORROW'S RESILIENCE
Great Diamond Island faces a range of coastal challenges, from sea level rise and shoreline erosion to storm impacts and aging infrastructure. Addressing these risks requires more than individual property improvements—it depends on informed residents, strong partnerships, and community-wide planning.
The GDI Partnership works with local, regional, and state organizations to bring educational programs, workshops, and planning initiatives to the island. Together, these efforts help residents better understand coastal risks, strengthen community connections, and prepare for the changes shaping Maine's coast.
THE RESOURCES below highlight the community-led efforts to identify Great Diamond Island's strengths, vulnerabilities, and priorities for building long-term resilience. Together, they document the planning process, community input, and strategies that continue to guide resilience initiatives across the island.

Facilitated by the Gulf of Maine Research Institute and Island Institute, this community resilience training workshop engaged residents in defining what they value most about Great Diamond Island, identifying climate vulnerabilities, infrastructure risks, and helping shape a community-driven framework for future resilience planning.
