Terms. The term of each member shall be five years, with eligibility for reappointment by the Mayor with consent of the Board of Trustees. Planning Board terms shall commence with the first day of the official Village year. Full terms filled for the first time shall be so fixed for five or less years and arranged so that, to the greatest practicable extent, the expiration of terms will be distributed evenly over the first five years after the initial appointments. If a vacancy shall occur, it shall be filled by appointment as above provided for the unexpired term only. Members shall serve after the expiration of their terms until their successors shall have been appointed and qualified.
