16 U.S.C. § 90b–1 — Exchange of property; cash equalization payments

When exercising the authority to acquire property by exchange, the Secretary may accept title to any non-federal property within the boundaries of the park and recreation areas. In exchange, the Secretary may give the person who owned that property any federally owned property under the Secretary's jurisdiction in the State of Washington that the Secretary classifies as suitable for exchange or other disposal. The values of the properties traded should be approximately equal; if they are not, the difference is equalized by a cash payment, either from the grantor to the Secretary or from the Secretary to the grantor, as the situation requires.
