16 U.S.C. § 410zz–2 — Expansion of boundaries

(a) In general: (1) The park's boundaries are modified to add about 3,460 acres, as shown on a map titled "Saguaro National Monument Additions," dated April 1994. (2)(A) The boundaries are further modified to add about 1,152 acres, as shown on a map titled "Saguaro National Park Proposed Boundary Adjustment," numbered 151/80,045G and dated December 2020. (B) That map must be on file and available for public inspection at National Park Service offices. (b) Land acquisition: (1) Within the added land, the Secretary may acquire land and land rights by donation, purchase with donated or appropriated money, transfer, or exchange — but cannot acquire land without the owner's consent unless the Secretary decides the land is being, or will be, developed in a way that harms the park's integrity. (2) With Arizona's consent, and following federal and state law, the Secretary may acquire land Arizona owns within the park's boundary. (3) If the Secretary can't acquire that state land, the Secretary may instead agree with Arizona to let the National Park Service manage that state land within the park. (c) Withdrawal: Subject to any existing valid rights, all federal land within the park is withdrawn from entry, use, or sale under public land laws, from mining claims under U.S. mining law, and from mineral and geothermal leasing and mineral-materials laws, and any amendments to those laws.
