Michigan Compiled Laws, Chapter 120. Port Districts § 120.113

Sec. 13. (1) An authority and 1 or more constituent units may enter into a contract or contracts for the acquisition, improvement, enlargement, or extension of port facilities and for the payment of the cost thereof by the contracting constituent units, with interest, over a period of not more than 40 years.

(2) Each contracting constituent unit shall pledge its full faith and credit for the payment of its obligations under the contract. If the constituent unit has taxing power, each year it shall levy a tax upon all real and personal property within the constituent unit, which may be imposed without limitation as to rate or amount, to the extent necessary for the prompt payment of that part of the contract obligations as shall fall due before the following year's tax collection. The tax shall be in addition to any tax which the contracting constituent unit may otherwise be authorized to levy and may be imposed without limitation as to rate or amount, but shall not be in excess of the rate or amount necessary to pay the contract obligation. If any contracting constituent unit at the time of its annual tax levy has on hand in cash any amount pledged to the payment of the current obligations for which the tax levy is to be made, then the annual tax levy may be reduced by that amount. For the purpose of obtaining the credit, funds may be raised by a contracting constituent unit in 1 or more of the following methods:

(3) A contracting constituent unit may agree to raise all or any part of its contract obligation by 1 or more of the methods enumerated in subsection (2) which may be available. The various powers granted in this act to a constituent unit shall be exercised by its governing body.

(4) If a constituent unit, other than a county, operating under this act elects to raise money to pay all or a portion of its share of the cost of a project by assessing the costs upon benefited lands, its governing body shall so determine by resolution and fix the district therefor. The governing body shall then cause a special assessment roll to be prepared and thereafter the proceedings in respect to the special assessment roll and the making and collection of the special assessments on the roll, shall be in accordance with the provisions of the statute or charter governing special assessments in the constituent unit, except that the total assessment may be divided into any number of installments not exceeding 30, and any person assessed shall have the right at the hearing upon the special assessment roll to object to the special assessment district previously established.
