The corporate authorities of any city with a population of less than 100,000 which has established a public hospital is authorized to issue and sell revenue bonds payable from the revenue derived from the operation of the hospital for the purpose of (1) reconstructing, repairing, remodeling, or extending, or (2) equipping or improving an existing hospital building or buildings, or any addition or extension thereto or (3) constructing and equipping a new hospital to replace an existing hospital and acquiring a site therefor, or (4) refunding any such revenue bonds theretofore issued from time to time when deemed necessary or advantageous in the public interest. These bonds shall be authorized by an ordinance without submission thereof to the electors of the city, shall mature at such time not to exceed 40 years from the date of issue, and bear such 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, payable annually or semiannually as the corporate authorities may determine, and may be sold by the corporate authorities in such manner as they deem best in the public interest. However, such bonds shall be sold at such price that the interest cost of the proceeds therefrom will not exceed 7% per annum, based on the average maturity of such bonds and computed according to standard tables of bond values.
With respect to instruments for the payment of money issued under this Section either before, on, or after the effective date of this amendatory Act of 1989, it is and always has been the intention of the General Assembly (i) that the Omnibus Bond Acts are and always have been supplementary grants of power to issue instruments in accordance with the Omnibus Bond Acts, regardless of any provision of this Act that may appear to be or to have been more restrictive than those Acts, (ii) that the provisions of this Section are not a limitation on the supplementary authority granted by the Omnibus Bond Acts, and (iii) that instruments issued under this Section within the supplementary authority granted by the Omnibus Bond Acts are not invalid because of any provision of this Act that may appear to be or to have been more restrictive than those Acts.
The amendatory Acts of 1971, 1972 and 1973 are not a limit upon any municipality which is a home rule unit.
