N.C. Gen. Stat. § 143B-1254
An authority shall consist of five commissioners appointed by the mayor, and he shall designate the first chairman.
Of the commissioners who are first appointed, two shall serve for a term of one year, two for a term of three years, and one for a term of five years, and thereafter, the terms of office for all commissioners shall be five years. A commissioner shall hold office until his successor has been appointed and qualified. Vacancies shall be filled for the unexpired term. Vacancies occurring by expiration of office or otherwise shall be filled in the following manner: The mayor and the remaining commissioners shall have a joint session and shall unanimously select the person to fill the vacancy; but if they are unable to do so, then such fact shall be certified to the resident judge of the superior court of the County in which the authority is located, and he shall fill the vacancy. The mayor shall file with the city clerk a certificate of the appointment or reappointment of any commissioner, and such certificate shall be conclusive evidence of the due and proper appointment of such commissioner. A commissioner shall receive no compensation for his services, but he shall be entitled to the necessary expenses, including traveling expenses, incurred in the discharge of his duties.
When the office of the first chairman of the authority becomes vacant, the authority shall select a chairman from among its members. An authority shall select from among its members a vice-chairman, and it may employ a secretary, technical experts and such other officers, agents and employees, permanent and temporary, as it may require, and shall determine their qualifications, duties, and compensation. An authority may employ its own counsel and legal staff. An authority may delegate to one or more of its agents or employees such powers or duties as it may deem proper.
