An Act To Allow Coastal Seawalls To Be Raised By Up To 2 Feet In Order To Accommodate Predicted Sea Level Rise

LD 228 amends Maine's Natural Resources Protection Act to allow the Department of Environmental Protection to approve a one-time 2-foot height increase for existing coastal seawalls in sand dune systems. This applies to seawalls already in place as of January 1, 2025, provided the increase meets all other department requirements. The bill also permits a similar 2-foot height allowance when replacing seawalls destroyed or threatened by storms. It directly affects coastal property owners and municipalities seeking to adapt existing infrastructure to rising sea levels and increased storm impacts.
