Appointments to the board shall be made for a period of four years. Initial terms shall be staggered to minimize expirations in any one year as follows: two members for one year, two members for two years, two members for three years and one member for four years.  Vacancies shall be filled by the council for the balance of the unexpired term.  A vacancy occurs when a member resigns, fails to qualify within fourteen days, dies, or has unexcused (as determined by the board) absences of twenty-five percent or more of the board meetings within any twelve-month period.  The presiding officer shall report such absence to the city council and upon receipt and approval of the report by the city council the office automatically becomes vacant. No person may serve more than two consecutive full terms on the board. Full terms begin July 1st and end June 30th.  However, members whose terms have expired shall continue to serve until a successor is appointed by the city council.  (Ord. 95/U-3255)
