Under Florida law, the State owns the land permanently submerged beneath navigable waters and the foreshore, while beachfront—or littoral—owners generally hold land to the mean high-water line. Littoral owners have special property rights, including access to the water, use and view of the water, and the right to acquire land gradually and imperceptibly added by accretion. By contrast, land suddenly exposed through avulsion remains with the owner of the formerly submerged land, ordinarily the State.
Florida's Beach and Shore Preservation Act authorizes beach-restoration projects and permits the State to establish a fixed erosion-control line, which replaces the fluctuating mean high-water line as the boundary between private upland and state land. After the line is recorded, upland owners retain their common-law littoral rights except the right to future accretions.
Following hurricane erosion, Destin and Walton County proposed depositing dredged sand along 6.9 miles of coast. The project would create roughly 75 feet of new dry beach seaward of the existing mean high-water line, which became the erosion-control line. Stop the Beach Renourishment, representing affected beachfront owners, argued that the project would eliminate their rights to future accretions and to continued contact with the water.
The Florida First District Court of Appeal agreed and set aside the permits, reasoning that the project unconstitutionally impaired those littoral rights. The Florida Supreme Court reversed. It held that the project created an avulsion, leaving the new beach in state ownership; characterized the right to accretions as a contingent future interest; and held that Florida law recognized no independent right to continual contact with the water apart from the right of access. The U.S. Supreme Court affirmed.
