N.C. Gen. Stat. § 153A-3: Effect of Chapter on local acts.

(a) Except as provided in this section, nothing in this Chapter repeals or amends a local act in effect as of January 1, 1974, or any portion of such an act, unless this Chapter or a subsequent enactment of the General Assembly clearly shows a legislative intent to repeal or supersede that local act.

(b) If this Chapter and a local act each provide a procedure that contains every action necessary for the performance or execution of a power, right, duty, function, privilege, or immunity, the two procedures may be used in the alternative, and a county may follow either one.

(c) If this Chapter and a local act each provide a procedure for the performance or execution of a power, right, duty, function, privilege, or immunity, but the local act procedure does not contain every action necessary for the performance or execution, the two procedures may be used in the alternative, and a county may follow either one; but the local act procedure shall be supplemented as necessary by this Chapter's procedure. If a local act procedure is being supplemented in such a manner, and there is a conflict or inconsistency between the local act procedure and this Chapter's procedure, the local act procedure shall be followed.

(d) If a power, right, duty, function, privilege, or immunity is conferred on counties by this Chapter, and a local act enacted earlier than this Chapter omits or expressly denies or limits the same power, right, duty, function, privilege, or immunity, this Chapter supersedes the local act.
