A.
A Zoning Board of Adjustment is hereby established pursuant to N.J.S.A. 40:55D-69 et seq., consisting of seven residents of the Borough appointed by the Mayor to serve for terms of four years from January 1 of the year of their appointment. The terms of the members first appointed shall be so determined that, to the greatest practicable extent, the expiration of such terms shall be distributed evenly over the first four years after their appointment, provided that the initial term of no member shall exceed four years. Thereafter the term of each member shall be for four years. Nothing in this chapter shall be construed to affect the terms of any present members of the Zoning Board of Adjustment, all of whom shall continue in office until the completion of the terms for which they were appointed.
B.
No member of the Zoning Board of Adjustment may hold any elective office or position under the Borough.
C.
A vacancy occurring otherwise than by expiration of term shall be filled for the unexpired term only.
D.
There shall also be appointed by the Mayor not more than two alternate members to said Zoning Board of Adjustment. The alternate members shall be designated at the time of appointment as "Alternate No. 1" and "Alternate No. 2." The terms of the alternate members shall be so determined that the initial terms shall extend evenly over the first two years after their appointment, provided that the initial terms of said alternate members shall not exceed two years. Thereafter, the terms of each alternate member shall be for 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.
