Michigan Compiled Laws, Chapter 125. Planning, Housing and Zoning § 125.22

Sec. 12. For the purpose of providing funds to meet the expenses of a regional planning commission any local governmental unit participating in the formation, functioning and support of the regional planning commission or any other local governmental unit wishing to contribute thereto may allocate funds for the purpose by official act of its legislative body. The proportion of the total amount of funds to be so provided by each participating local governmental unit may be suggested by the regional planning investigating committee or prepared as a proposed budget by the regional planning commission and submitted to the legislative bodies of the participating local governmental units. Each legislative body of the participating governmental units may appropriate its share of the funds to be allocated for the use of the regional planning commission by the adoption of a legislative act which is identical with a similar act or acts as adopted by the other participating local governmental units. The services of personnel, the use of equipment and office space, and the provision of special services, may be accepted from any participating local governmental unit and may be considered a part of the financial support of that governmental unit.
