A.
A Zoning Board of Adjustment is hereby established, which shall consist of seven regular members and two alternate members. All regular and alternate members shall be residents of the Township of Middle and shall be appointed by the governing body. Alternate members shall be designated at the time of appointment by the governing body as "Alternate No. 1" and "Alternate No. 2." The terms of the members first appointed under this act shall be so determined that, to the greatest practicable extent, the expiration of such terms shall be distributed, in the case of regular members, evenly over the first four years after their appointment, and, in the case of alternate members, evenly over the first two years after their appointment, provided that the initial term of no regular member shall exceed four years and that the initial term of no alternate member shall exceed two years. Thereafter, the term of each regular member shall be four years; and the term of each alternate member shall be two years. Alternate members may participate in discussions of the proceedings but may not vote except in the absence or disqualification of a regular member. A vote shall not be delayed in order that a regular member may vote instead of an alternate member. In the event that a choice must be made as to which alternate member is to vote, Alternate No. 1 shall vote.
B.
No member of the Zoning Board of Adjustment may hold any elective office or position under the Township.
C.
A vacancy occurring otherwise than by expiration of the term shall be filled for the unexpired term only.
D.
If the Board of Adjustment lacks a quorum because any of its regular or alternate members are prohibited by N.J.S.A. 40:55D-69 from acting on a matter due to the members' personal or financial interest therein, Class IV members of the Planning Board shall be called upon to serve, for that matter only, as temporary members of the Board of Adjustment. The Class IV members of the Planning Board shall be called upon to serve in order of seniority of continuous service to the Planning Board until there is a minimum number of members necessary to constitute a quorum to act upon the matter without any personal or financial interest therein, whether direct or indirect. If a choice has to be made between Class IV members of equal seniority, the Chairman of the Planning Board shall make the choice.
