16 U.S.C. § 428p–1 — Land acquisition related to Fort Donelson National Battlefield

(a) Acquisition authority Subject to the limits in subsections (b) and (c), the Secretary of the Interior may acquire land, interests in land, and improvements on that land for the battlefield. The Secretary can only do this in three ways: buying from a willing seller using appropriated or donated money, accepting a donation, or trading with a willing owner. The Secretary cannot use condemnation here. (b) Land eligible for acquisition The Secretary may acquire land under subsection (a) in two situations. First, the land can be within the battlefield boundaries described in section 428p(b). Second, the land can be outside those boundaries — but only if the American Battlefield Protection Program has identified it as part of the battlefield connected to Fort Donelson, or if the Secretary otherwise decides that acquiring it will protect resources critical to the 1862 Battle of Fort Donelson and the Union campaign that captured the fort. (c) Boundary revision Whenever the Secretary acquires land or land interests under subsection (b)(2) — meaning land outside the original boundary — the Secretary must revise the battlefield's boundaries to include that newly acquired property. (d) Limitation on total acreage of park No matter how much land is added, the Fort Donelson National Battlefield's total area can never be more than 2,000 acres.
