Bonds issued under Section 9-1 hereof shall be payable solely from the revenue derived from the operation of the swimming pool, or the artificial ice skating rink, and shall not in any event constitute an indebtedness of the park district within the meaning of any constitutional or statutory limitation. It shall be plainly stated on the face of each bond that the bond has been issued under Sections 9-1 to 9-1f hereof, inclusive, and that it does not constitute an indebtedness of the park district within any constitutional or statutory limitation.
The bonds shall be sold in such manner and upon such terms as the board shall determine. The minimum price at which they may be sold shall be such that the interest cost to the park district of the proceeds of the bonds shall not exceed the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, computed to maturity, according to the standard table 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.
