The board of the District created under this Act may issue and sell revenue bonds, payable from the revenue derived from taxes imposed under Section 30, for any of the purposes enumerated in this Act or for the purpose of refunding any revenue bonds theretofore issued from time to time when considered necessary or advantageous in the public interest. These bonds shall be authorized by an ordinance without submission thereof to the electors of the District, shall mature at any time not to exceed 40 years from the date of issue, shall bear any rate of interest not to exceed the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, that the board may determine, and may be sold by the board in any manner that it deems best in the public interest. However, the bonds shall be sold at any price that the interest cost of the proceeds therefrom will not exceed the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, based on the average maturity of the bonds and computed according to standard tables of bond values. No member of the board shall have any personal economic interest in any bonds issued in accordance with this Section.
The board of the District, when availing itself of the provisions of this Section, shall adopt an ordinance describing in a general way the purposes for which the bonds will be issued. The ordinance shall fix the amount of revenue bonds proposed to be issued, the maturity, interest rate, and all details in respect thereof, including any provision for redemption prior to maturity, with or without premium, and upon any notice that may be provided by the ordinance.
Revenue bonds issued under this Section shall be signed by the chairman and secretary of the board or any other officers that the board may by ordinance direct to sign the bonds, and shall be payable from revenue derived from taxes imposed under Section 30. These bonds may not in any event constitute an indebtedness of the District within the meaning of any constitutional provision or limitation. It shall be plainly written or printed on the face of each bond that the bond has been issued under the provisions of this Section, that the bond, including the interest thereon, is payable from the revenue pledged to the payment thereof, and that it does not constitute an indebtedness or obligation of the District within the meaning of any constitutional or statutory limitation or provision. No holder of any such revenue bond may compel any exercise of the taxing power of the District to pay the bond or interest thereon.
The District may not issue any bonds under this Section unless a public hearing, with adequate notice to the public, is held prior to the issuance of the bonds. Notice of the hearing giving the purpose, time, and place of the hearing shall be published at least once, not more than 30 nor less than 15 days before the hearing, in one or more newspapers published in the District.
