Portland's tidal shoreline, Fore River, Back Cove and Presumpscot River frontage is covered by a mandatory Shoreland Overlay Zone (Portland, ME Land Use Code, Chapter 14, Art. 11) implementing 38 M.R.S. § 435 et seq. The overlay extends 250 feet inland of the high-water line / coastal wetland edge, imposes a 75-foot structural setback in most cases and requires an Other Land Use Permit for any pier, seawall, vegetation removal or land alteration.
Maine's Mandatory Shoreland Zoning Act (38 M.R.S. § 435 et seq.) requires every municipality to adopt and enforce shoreland zoning within 250 feet of the normal high-water line of tidal waters, great ponds and rivers, the upland edge of coastal and freshwater wetlands, and within 75 feet of streams. Portland implements this through Chapter 14 of the Land Use Code with shoreland and resource-protection provisions at Sec. 14-446 to 14-450 and through the Other Land Use Permit checklist. Applications must include a boundary survey showing the Highest Astronomical Tide (HAT) Line, the 75-foot setback line, the 250-foot shoreland boundary, the Mean High Water Line, Mean Low Water Line and the flood zone line; existing vegetation and a replanting plan; and a Maine DEP-certified erosion-control contractor. Construction of piers, seawalls and other shoreline structures requires plans stamped by a Maine-licensed architect or engineer, a Natural Resources Protection Act (NRPA) permit from Maine DEP, and a US Army Corps of Engineers permit under Sections 9, 10 and 404 (Rivers & Harbors Act / Clean Water Act). The Board of Harbor Commissioners has separate jurisdiction over harbor structures. Vegetation removal is constrained by the state floor: cleared openings are prohibited within 75 feet of the normal high-water line except for approved boat access, and a well-distributed vegetation buffer must remain.
Shoreland-zone violations receive heightened treatment. Chapter 6, Sec. 6-1(a)(4) provides that when violations occur in a shoreland area as defined in Sec. 14-447 (or when the court finds the violation willful), the violator 'shall be ordered to correct or abate the violation' unless abatement would create a public-health hazard, substantial environmental damage or substantial injustice. Significant-code-violation fines run $200–$2,500/day; after a written notice $500–$5,000/day; after a second notice $1,500–$10,000/day; up to $25,000/day for repeat violations. The City must also be awarded attorney fees, expert witness fees and costs if it prevails (Sec. 6-1(a)(5)). 30-A M.R.S. § 4452 likewise authorizes corrective injunctions, mandatory restoration plantings and treble economic-benefit penalties.
