The term of office of each member shall be four years and until the appointment and qualification of his or her successor. Upon enlargement of the commission by two members, as provided in Section 56332, the new members first appointed to represent independent special districts shall classify themselves by lot so that the expiration date of the term of office of one new member coincides with the existing member who holds the office represented by the original two-year term on the commission and the term of office of the other new member coincides with the existing member who holds the office represented by the original four-year term on the commission. The body which originally appointed a member whose term has expired shall appoint his or her successor for a full term of four years. Any member may be removed at any time and without cause by the body appointing that member. The expiration date of the term of office of each member shall be the first Monday in May in the year in which the term of the member expires, unless procedures adopted by the commission specify an alternate date to apply uniformly to all members. However, the length of a term of office shall not be extended more than once. Any vacancy in the membership of the commission shall be filled for the unexpired term by appointment by the body which originally appointed the member whose office has become vacant.
The chairperson of the commission shall be selected by the members of the commission.
Commission members and alternates shall be reimbursed for the actual amount of their reasonable and necessary expenses incurred in attending meetings and in performing the duties of their office. The commission may authorize payment of a per diem to commission members and alternates for each day while they are in attendance at meetings of the commission.
