Michigan Compiled Laws, Chapter 280. Drain Code of 1956 § 280.464

Sec. 464. (1) A drainage board is created for each project petitioned for under this chapter. Except as otherwise provided in subsection (2), the drainage board shall consist of the drain commissioner of the county, the chairperson of the county board of commissioners, and the chairperson of the board of county auditors. If there is no board of county auditors in the county, then the chairperson of the finance committee of the county board of commissioners shall be a member of the drainage board. If there is neither a board of county auditors nor finance committee, then the chairperson of the county board of commissioners shall select from time to time 1 member of the county board of commissioners to be a member of the drainage board. If a member of the drainage board who is a member of the county board of commissioners, as provided in this section or section 487,  1 is interested in a project petitioned for under this chapter, by reason of his or her holding an elected or appointed office in a public corporation to be assessed for the cost of the project, he or she is disqualified to act as a member of the drainage board with respect to the project. In that case the vice-chairperson or chairperson pro tempore of the county board of commissioners or of the finance committee of the county board of commissioners, if not also disqualified, shall act as the member. If the vice-chairperson or chairperson pro tempore is disqualified, the drain commissioner of the county shall designate a member of the county board of commissioners who is not disqualified to act as a member of the drainage board for the project. The chairperson of the county board of commissioners and any member of a county board of commissioners serving on the drainage board shall receive the compensation, mileage, and expenses as provided by the drainage board. However, compensation paid to a member shall not exceed $25.00 per diem, exclusive of mileage and expenses, for attendance at drainage board meetings. The county drain commissioner shall be chairperson of the drainage board. The chairperson shall keep minutes of the proceedings of the drainage board and all records and files of the board shall be kept in his or her office. In counties of less than 500,000 population, the commissioner shall be paid the same compensation as other members of the drainage board.

(2) If a county is organized under a charter adopted under 1966 PA 293, MCL 45.501 to 45.521, and the charter prescribes an elected county executive, the drainage board shall consist of the following members:

(3) In a county described in subsection (2), the requirements in this chapter for substantive actions and determinations shall be followed in administering each project petitioned for under this chapter, subject to and in accordance with any applicable provisions of the county charter.
