For the initial board one member shall be appointed for a term of five years, one for a term of four years, one for a term of three years, one for a term of two years, and one for a term of one year. Members are removable for cause by the appointing authority upon written charges and after public hearing. Vacancies shall be filled for the unexpired term of a member whose term becomes vacant. The compensation for the members of the board of adjustment is the same as for the members of the board of trustees.
