Whenever the board of commissioners of any such forest preserve district determines to construct, equip, acquire, extend or improve any such facility or facilities or any combination thereof and to issue bonds pursuant to Sections 18.1 through 18.10 of this Act to pay the cost or purchase price thereof, such board shall adopt an ordinance describing in a general way the contemplated facility or facilities and setting forth the estimated cost or purchase price. Any such ordinance shall be published within 10 days after passage at least once in a newspaper published in such district and having a general circulation therein to be designated by such board, and no such ordinance shall take effect until 10 days after it is so published. It shall not be necessary that the ordinance refer to plans and specifications nor that there be on file for public inspection prior to adoption of such ordinance detailed plans and specifications of such contemplated facility or facilities or any combination thereof. Such board may provide that the ordinance authorizing the issuance of any such bonds shall be effective, operative and valid without the submission thereof to the voters of such district for approval, notwithstanding the provisions of Section 13 of this Act.
Any such ordinance shall prescribe the method of defraying the cost of the contemplated facility or facilities and fix the amount of the revenue bonds proposed to be issued, the interest rate and the maturities thereof. Such bonds shall be in such form and be executed in such manner, be payable in such medium of payment at such place or places, be subject to such terms of redemption, prior to maturity, with or without premium, and may be made registrable as to principal, all as such ordinance may provide. The ordinance shall also pledge the revenue derived from the operation of such facility or facilities, or any combination thereof, constructed, equipped, acquired, extended or improved in whole or in part with the proceeds of such bonds for the purpose of paying maintenance and operation costs and paying the principal and interest of such bonds so issued for the facility or facilities. The ordinance may contain such covenants which shall be a part of the contract between the district and the holders of such bonds with respect to creating accounts and the application of the flow of funds through such accounts, and the restrictions upon the issuance of additional revenue bonds thereafter, all as such board may deem necessary or advisable for the assurance of the payment of the bonds thereby authorized.
Such bonds shall be executed by the president and by the secretary or treasurer of the board of such forest preserve district. The president of such board may execute such bonds by his facsimile signature which may be imprinted, engraved or otherwise reproduced on such bonds and on the interest coupons attached thereto. Any bonds bearing the signature or facsimile of an officer in office at the date of signing thereof are valid and binding for all purposes, notwithstanding that before delivery thereof, such person whose signature or facsimile appears thereon has ceased to hold such office.
