The purpose of AS 41.21.430 - 41.21.445 is to empower the governor to restrict state-owned land and water described in AS 41.21.435 to use as a public recreation area. Under AS 38.05.300, state land, water, or land and water containing more than 640 acres may be closed to multiple purpose use only by act of the legislature. Because the area described in AS 41.21.435 exceeds 640 acres, AS 41.21.430 - 41.21.445 are intended to provide for the closing of the described land and water to multiple purpose use in conformity with AS 38.05.300 and its subsequent designation as a special purpose site in accordance with art. VIII, § 7, of the Constitution of the State of Alaska.
