Full Breakdown

Maine's coastal development framework rests on multiple overlapping statutes. ) implements; the federally approved Maine Coastal Program is housed at the Maine Department of Marine Resources and exercises federal consistency review over federal agency actions, permits, and grants affecting the coastal area. , requires EVERY Maine municipality to adopt and enforce shoreland zoning within 250 feet (horizontal distance) of the normal high-water line of any great pond, river, freshwater wetland, or tidal water (and within 75 feet of streams). The state Shoreland Zoning Standards (06-096 CMR Chapter 1000) set a 75-foot structure setback (standard), minimum lot sizes, a vegetated buffer, impervious-surface caps, and restrictions on nonconforming-structure expansion (38 MRS § 439-A).

, requires a Maine DEP permit for any activity that 'alters' a coastal wetland, coastal sand dune system, fragile mountain area, freshwater wetland, great pond, river/stream/brook, or significant wildlife habitat. (4) Submerged-lands leasing of state-owned intertidal and submerged coastal land is administered under 12 MRS § 1862 by the Maine Bureau of Parks and Lands. The Maine Coastal Sand Dune Rules (06-096 CMR Chapter 355) impose strict prohibitions on construction in V-zones and in the frontal-dune system under projected sea-level-rise scenarios.

Violations & Penalties

NRPA (38 MRS § 480-A et seq.) violations carry administrative civil penalties up to $25,000 per day per violation under 38 MRS § 349, plus restoration orders and injunctive relief. Shoreland zoning violations are enforced by the certified municipal CEO under 30-A MRS § 4452 with penalties of $100-$2,500 per first violation and $500-$25,000 for subsequent violations.

Frequently Asked Questions

What is Maine's mandatory shoreland zoning?
Per 38 MRS § 435 et seq., every Maine municipality MUST adopt and enforce shoreland zoning within 250 feet of the normal high-water line of any great pond, river, freshwater wetland, or tidal water, and within 75 feet of streams. The state Shoreland Zoning Standards (06-096 CMR Chapter 1000) impose a 75-foot structure setback, minimum vegetated buffer, impervious-surface caps, and strict limits on expanding nonconforming structures.
Do I need a state permit to build a dock or seawall in Maine?
Yes. The Natural Resources Protection Act (38 MRS § 480-A et seq.) requires a Maine DEP permit (Permit by Rule, Tier 1/2/3 Individual Permit, or General Permit) for any activity that alters a coastal wetland, sand dune, river, stream, brook, great pond, or significant wildlife habitat. Coastal Sand Dune Rules (06-096 CMR Chapter 355) impose additional restrictions on V-zone and frontal-dune construction.
What is 38 MRS § 1801?
It is Maine's Coastal Management Policies statute, the state-law foundation for the federally approved Maine Coastal Program under the Coastal Zone Management Act of 1972. It declares nine policy goals, port development, marine resource protection, scenic/natural area preservation, water-quality restoration, protection of coastal hazard areas, that all state and local agencies must follow when their actions affect the coastal area. The Maine Department of Marine Resources administers federal consistency review.
