The bylaws may provide for the division of the service area of the corporation into two or more districts for designating seats on its governing board. The bylaws also may provide that a district have two or more seats on its governing board. One or more members may be elected from each district to fill the seats designated for the district. The entire membership must vote on election of board members even though only members from certain geographic districts are qualified candidates for district board seats. The bylaws may provide further that board elections be staggered so that no less than one-third or more than one-half of all board members' terms expire each year.
