16 U.S.C. § 425l — Acquisitions and conveyances

(a) Acquisition. Except as described in paragraph (2), the Secretary may acquire land and land interests within the park by donation, by purchase with donated or appropriated funds, or by exchange. Land marked "P04-04" on the September 1990 map referenced in section 425k(a) may only be acquired by donation. Land marked "P04-01," "P04-02," and "P04-03" on that map may only be acquired by donation, purchase from willing sellers, or exchange. (b) Conveyance of lands excluded from park. Following existing law, the Secretary may exchange federal land and interests that got excluded from the park under section 425k(b), in order to acquire land within the new park boundary. If any of that excluded federal land or interest isn't exchanged within five years after December 11, 1989, the Secretary may sell it to the highest bidder, under rules the Secretary sets — but the sale price can never be less than the land's fair market value, as the Secretary determines it. Any land sold or exchanged this way must come with terms and conditions that, in the Secretary's judgment, will protect the battlefield's setting. Despite any other law, the net proceeds from these sales or exchanges must go — subject to available appropriations — toward buying land and interests within the park. (c) Alternative access. To help the United States acquire existing easements or access rights across federal park land, and to give the holders of those rights alternative access across non-park land, the Secretary may acquire — by donation, purchase with donated or appropriated funds, or exchange — similar land interests outside the park. The Secretary may then trade that non-park land or interest to the holders of the existing park easements or access rights, in exchange for them giving up their rights to the United States, with or without an extra cash payment to balance the property values. Nothing here stops the Secretary from acquiring outstanding access rights across federal park land by donation, purchase, or exchange in the ordinary way. (d) Conservation easements. The Secretary may accept donated conservation easements on land next to the park. These easements must protect the scenic and historic resources on both the park land and the adjacent land, or preserve the undeveloped or historic look of the park as seen from inside or outside it. (e) Other provisions. Within the area bounded by the Orange Turnpike, the Orange Plank Road, and McLaws Drive, the Secretary may not acquire any "improved property" (as section 425m defines it) without the owner's consent — unless the Secretary decides the property is being used, or is threatened with being used, in a way that's harming or would harm the park.
