Mich. Comp. Laws § 280.54
The commissioner shall prepare and file in his office his order designating a drainage district and give it a name or number and describe therein the boundaries of the district by streets or highways or parcels of land for each of the several tracts or parcels of land included therein and the counties, townships, cities, villages and state trunk line highways which would be benefited by the construction of the drains and would be liable to assessment therefor, also a description of the drains as determined by him, showing the beginning, route, terminus, type of the proposed construction and the estimated cost of such proposed construction. The commissioner shall give notice of filing the order designating a drainage district by publishing a notice in a newspaper of general circulation in the county, or a newspaper of general circulation in the area where the drainage district boundaries are located, which notice shall give a general description of the route of the proposed drain or drains and of the drainage district as shown by the order.
At any time after the order designating a drainage district and giving it a name or number has been filed in the office of the drain commissioner, the order may be amended as to the name or number of the drain at any time by presenting to the drain commissioner of the county a petition signed by no less than 5 land owners whose land is traversed by the drain, which petition shall state the then present name or number of the drain and the change or changes to be made in the name or number. Upon receipt of such petition, and if in the drain commissioner's opinion it is to the best interest of all concerned that the name or number be changed, he shall make his order amending the name or number, and thereafter the drainage district shall be known by such name or number. The drain commissioner shall forthwith post such signs upon the drain as he may deem advisable for public notice of the new name or number.
