N.C. Gen. Stat. § 153A-4: Broad construction.

It is the policy of the General Assembly that the counties of this State should have adequate authority to exercise the powers, rights, duties, functions, privileges, and immunities conferred upon them by law. To this end, the provisions of this Chapter and of local acts shall be broadly construed and grants of power shall be construed to include any powers that are reasonably expedient to the exercise of the power.
