N.C. Gen. Stat. § 146-34: Agencies may establish agreed boundaries.

Every State agency may establish agreed boundaries between lands allocated to it or under its control, and the lands of any other owner, subject to the approval of the Governor and Council of State. The Department of Administration is authorized to establish agreed boundaries between State lands not allocated to or under the control of any other State agency and the lands of any other owner, subject to the approval of the Governor and Council of State. The Attorney General shall represent the State in all proceedings to establish boundaries which cannot be established by agreement. (1957, c. 584, s. 3; G.S., s. 143-145.2; 1959, c. 683, s. 1.)
