Summary

The Secretary may get land, water, and interests inside the seashore by donation, purchase with donated or approved funds, or by exchange. State or local government property can be taken only if the owner agrees. The Secretary can also buy up to 400 acres on the mainland near Biloxi-Gulfport, Mississippi, for an administrative site. Federal property inside the seashore or that mainland site can be transferred to the Secretary for seashore use if the agency in charge agrees. When the United States buys a house that is owned by a person, the owner may keep the right to live there for noncommercial residential use either until the owner or spouse dies (whichever is later) or for up to 25 years, whichever the owner chooses. That right can be transferred. The Secretary must pay the owner the fair market value of the property at purchase, minus the fair market value of the right the owner keeps. “Improved residential property” means a single-family year-round home started before January 1, 1967, that is the owner’s main home when bought, plus up to three acres needed for its use (marsh, beach, or waters needed for public access may be left out). The Secretary can end a retained right if it conflicts with the seashore’s purposes and must pay the fair market value of the unused part. From willing sellers only, the Secretary may acquire certain Cat Island lands: the parcel above the mean high tide line in Harrison County; an easement over the about 150‑acre Boddie Family Tract; other Cat Island land outside the 2,000‑acre mapped area; and submerged land within 1 mile seaward of Cat Island (the “buffer zone”), except submerged land owned by the State of Mississippi may be taken only by donation. Land acquired under these rules will be managed by the National Park Service Director. The State of Mississippi is not required to give any buffer-zone rights as a condition for creating the buffer zone. The seashore boundary will be changed only after the land is actually acquired.

Sections 459h to 459h–10 of this title, referred to in subsec. (e)(1)(C)(ii), (2)(B), was in the original “this title”, and was translated as reading “this Act”, meaning Pub. L. 91–660, which enacted sections 459h to 459h–10 of this title, to reflect the probable intent of Congress, because Pub. L. 91–660 does not contain titles.
