Terms. The term of the member composing Class I shall correspond with his official tenure; the Mayor's designee shall serve at the pleasure of the Mayor during the Mayor's official tenure. The terms of the members composing Class II and Class III shall be for one year or shall terminate at the completion of their respective terms of office, whichever occurs first, except for a Class II member who is also a member of the Environmental Commission. The term of the Class II or Class IV member who is also a member of the Environmental Commission shall be for three years or shall terminate at the completion of his term of office as a member of the Environmental Commission, whichever occurs first. The term of a Class IV member who is also a member of the Board of Adjustment (if such Board exists) or Board of Education shall terminate whenever he is no longer a member of such other body or at the completion of the Class IV term, whichever occurs first. The terms of all Class IV members first appointed pursuant to this chapter shall be so determined that to the greatest practicable extent the expiration of such terms shall be evenly distributed over the first four years after their appointment as determined by resolution of the Township Committee; provided, however, that the term of any member shall not exceed four years, and further provided that nothing herein shall affect the term of any present member of the Planning Board, all of whom shall continue in office until the completion of the terms for which they were appointed. In the event that a member shall resign from the Planning Board and leave an unexpired term, appointment shall be made to fill the unexpired term only. Thereafter all Class IV members shall be appointed for terms of four years except as otherwise herein provided. All terms shall run from January 1 of the year in which the appointment is made. No member of the Planning Board shall be permitted to act on any matter in which he has, either directly or indirectly, any personal or financial interest. Any member other than a Class I member, after a public hearing if he requests one, may be removed by the governing body for cause.
