Mich. Comp. Laws § 141.120c
When a borrower has outstanding any parking revenue bonds issued under the provisions of this act, it may thereafter levy special assessments against properties specially benefited by the parking facilities originally financed by the bonds, but no assessment shall be made at large, and may issue special assessment bonds therefor in anticipation of the payment of the special assessments for the purpose of providing for the retirement of the outstanding bonds in whole or in part. The special assessment bonds may pledge the full faith and credit of the public corporation issuing them, as determined by the governing body of the public corporation. The special assessment bonds may be issued to include the amount of any premium to be paid upon the calling of the parking revenue bonds to be refunded or if such bonds are not callable, any premium necessary to be paid in order to secure the surrender of the bonds to be refunded; but the amount of the premium so included shall not exceed 5% of the principal amount of the bonds to be refunded. The procedures for levying the special assessments and for issuing the special assessment bonds shall be the same as that provided by charter or other applicable law. Nothing in this section shall be construed as providing for the refunding of noncallable unmatured bonds without the consent of the holders thereof.
