The bonds shall be payable from and may be issued in anticipation of payment of the proceeds of any of the methods of financing described in section 14 or elsewhere in this act or as may be provided by law. A political subdivision within the geographical boundaries of the authority may contract to make payments, appropriations, or contributions to the authority of the proceeds of taxes, special assessments, or charges imposed and collected by the political subdivision or out of any other funds legally available and may pledge its full faith and credit in support of its contractual obligation to the authority. The contractual obligation shall not constitute an indebtedness of a political subdivision within a statutory or charter debt limitation. If the authority has issued bonds in anticipation of payments, appropriations, or contributions to be made to the authority pursuant to contract by a political subdivision having the power to levy and collect ad valorem taxes, the political subdivision may obligate itself by the contract, and thereupon may levy a tax on all taxable property in the political subdivision, which tax as to rate or amount will be as provided in section 6 of article IX of the state constitution of 1963 for contract obligations in anticipation of which bonds are issued, to provide sufficient money to fulfill its contractual obligation to the authority.

The authority may agree to repay the advances or pay for the property within a period not exceeding 10 years, from the proceeds of its bonds or from other funds legally available for that purpose, with or without interest as may be agreed at the time of advance or of repayment. The obligation of the authority to make the repayment or payment may be evidenced by a contract or note or notes, which contract or note may pledge the full faith and credit of the authority.

    (4) A political subdivision desiring to enter into a contract under subsection (1) shall authorize, by resolution of its governing body, the execution of the contract, which resolution shall be published in a newspaper of general circulation within the political subdivision, and the contract may be executed without a vote of the electors on the contract upon the expiration of 90 days after the date of the publication unless, within the 90-day period, a petition signed by not less than 5% of the registered electors residing within the limits of the political subdivision is filed with the clerk of the political subdivision requesting a referendum upon the execution of the contract, and in that event the contract shall not be executed until approved by the vote of a majority of the electors of the political subdivision qualified to vote and voting on the contract at a general or special election to be held not more than 90 days after the filing of the petition.

    (5) If the bonds or notes sold by the authority involve the pledge or use of state collected or administered funds, the authority shall seek the approval of the state transportation commission.
