Maine Infrastructure Adaptation Fund
General information
The purpose of the Maine Infrastructure Adaptation Fund is to provide one-time funding to municipal, tribal, and infrastructure districts to adapt their critical infrastructure to reduce vulnerability to climate change. The goal of this program is to reduce the existing infrastructure risk to climate change impacts, such as sea level rise, increased precipitation, and other related climate risks, and provide increased resilience.
Eligible activities and funding amounts: 1) scoping and design, with a maximum grant limit of $75,000 2) construction projects, with a maximum grant limit of $3,000,000. MaineDOT posted a notice in December 2025, and the purpose of the notice is to give eligible entities an opportunity to start thinking about potential projects before the Request for Applications opens in late March 2026.
