16 U.S.C. § 218a — Abraham Lincoln Birthplace National Historical Park, Kentucky

(a) In general: Once the Secretary of the Interior acquires the Knob Creek Farm land under (b), the boundary of the Abraham Lincoln Birthplace National Historical Park is revised to include it, and the Secretary administers the acquired land as part of the historic site. (b) Acquiring Knob Creek Farm: The Secretary of the Interior can acquire — by donation only — the approximately 228 acres of Knob Creek Farm in Larue County, Kentucky, as shown on a specific 1998 National Park Service map, which is kept on file for public inspection at the appropriate National Park Service offices. (c) Study and report: The Secretary of the Interior had to study Knob Creek Farm and, within one year of November 6, 1998, submit a report to Congress with the results. The study had to: (1) identify significant resources tied to Knob Creek Farm and Lincoln's early boyhood; (2) evaluate threats to the long-term protection of the farm's cultural, recreational, and natural resources; and (3) examine incorporating the farm into the park's operations and set out a strategic management plan for doing so — which, in developing it, meant the Secretary had to (A) determine what infrastructure and property improvements the farm needs to meet National Park Service standards, (B) identify current and potential recreational, interpretive, and educational uses of the farm, and (C) project the costs and potential revenues of acquiring, developing, and operating it. (d) Congress authorized whatever money is necessary to carry out the study required by subsection (c).
