Mich. Comp. Laws § 123.763
Whenever lands in any municipality are assessed by the board of public works for all or any part of the cost of a project, the governing body of the municipality by resolution adopted by 3/5 of its members elect may agree that in the event of delinquency in the collection of assessments against lands within the municipality, it will advance the amount of the delinquency to the extent necessary to pay principal and interest on any bonds issued in anticipation of the assessments, as the same mature. If moneys are so advanced by any municipality, then it shall be reimbursed therefor from the collection of the delinquent assessments and if collections from special assessments are not sufficient to reimburse any municipality making such advancements, within a 5-year period from the date of advancement, then the board of public works shall reassess the district as in the first instance in order to provide for the payment of the sum so advanced.
