Stop the Beach Renourishment, Inc. v. Florida Department of Environmental Protection, et al., 130 S. Ct. 2592 (U.S. 2010)

(owners of beach front property sued local government and state claiming that beach restoration projects involving placement of sand along beaches seaward from mean high-water line (which was the boundary between state's submerged land and owner's properties) were unconstitutional takings of their private property, but FL Supreme Court held that no taking occurred; U.S. Supreme Court affirmed - change in mean high-water line resulted from sudden avulsion rather than gradual accretion, thus newly exposed land remained property of state since boundary remained fixed).
