16 U.S.C. § 160b: Land acquisitions

The Secretary may acquire lands or interests therein within the boundaries of the park by donation, purchase with donated or appropriated funds, or exchange. In any case in which only a portion of a tract of land is within the boundaries of the park, the Secretary may acquire all or any portion of the land outside of such boundaries in order to minimize the payment of severance costs. Any land acquired pursuant to subparagraph (A) outside of the park boundaries may be exchanged by the Secretary for non-Federal lands within the park boundaries. Any portion of land acquired outside the park boundaries and not utilized for exchange shall be reported to the General Services Administration for disposal under chapters 1 to 11 of title 40 and division C (except sections 3302, 3307(e), 3501(b), 3509, 3906, 4710, and 4711) of subtitle I of title 41. Any Federal property located within the boundaries of the park may be transferred without consideration to the administrative jurisdiction of the Secretary for the purposes of the park. any land managed by the Bureau of Land Management within the boundaries of the park, as depicted on the map described in section 160a–1(a) of this title ; and any additional public land identified by the Bureau of Land Management as appropriate for transfer within the boundaries of the park. Any land located within or adjacent to the boundaries of the park that is owned by the State of Minnesota (or a political subdivision of the State) may be acquired by the Secretary only through donation or exchange. On completion of an acquisition from the State under clause (i), the Secretary shall revise the boundaries of the park to reflect the acquisition. In exercising the authority to acquire property under this section, the Secretary shall give immediate and careful consideration to any offer made by any individual owning property within the park area to sell such property to the Secretary. In considering such offer, the Secretary shall take into consideration any hardship to the owner which might result from any undue delay in acquiring his property.
