Unless otherwise provided by other provisions of the City Code or City Charter, all board and commission appointments shall be made by the Mayor with the approval of the Council prior to the expiration of an existing term. The term of each appointee shall be established and stated at the time of his or her appointment, and terms of present board and commission members may be reestablished and changed so as to give effect to this section. No board or commission member shall be appointed to more than three full consecutive terms. New appointees shall assume office on the first day of the first month following their appointment and qualification or on the first day of the first month following the expiration of the prior term and qualification, whichever shall occur last. Provided, however, that, all appointees to boards and commissions shall hold office until their successor is appointed and qualified. All vacancies shall be filled in the same manner as for an expired term, but the appointment shall be effective immediately when made and only for the unexpired term. No appointed board or commission member shall be an employee of the city, but an ex-officio member may be so employed. All appointed board and commission members shall serve without remuneration, but may be reimbursed for out-of-pocket expenses incurred in the performance of their duties when the expenses have been authorized by the Council before they were incurred. The Chairperson, Vice-Chairperson and the Secretary shall be chosen from and by the board or commission membership annually to serve for one year. Provided, however, that, no Chairperson shall be elected who has not completed at least one year as a member of the board or commission. Any board or commission member may be removed by the Council by a four-fifths vote after written notice of the charges against him or her and hearing thereof and his or her position filled as any other vacancy. Each board and commission shall establish their own meeting dates and times and conform to M.S. Chapter 13D, regarding open meetings, as amended from time to time. The City Administrator shall be an ex-officio member of all boards and commissions; provided that, if he or she is unable to attend a meeting or act in the capacity of the membership, he or she may be represented by his or her assistant or some person duly authorized by him or her. Except as otherwise provided, this section shall apply to all boards and commissions.
