The Authority may, with the consent of the City Council expressed by ordinance, and pursuant to referendum hereinafter provided borrow money and incur an indebtedness and issue bonds therefor in the amount or amounts not to exceed in the aggregate 2% of the total value of the taxable property of the Authority as equalized or assessed by the Department of Revenue for the purpose of exercising its powers under this Article, including but not to be limited to the purpose of project planning, the purchasing, leasing, condemning or otherwise acquiring site property, the construction and furnishing of all buildings and other improvements directed pursuant to this Article including all reasonable landscape and site preparation and including interest on its bonds for the period of construction and not exceeding one year thereafter; and to issue general obligation bonds as evidence of the indebtedness incurred. In addition to other purposes, such bonds may be issued for the purpose of refunding outstanding general obligation bonds of the Authority, provided that any refunding bonds will not require consent of the City Council. Such bonds shall be issued in the corporate name of the Authority and they shall be sealed with the corporate seal of the Authority and signed by the chairman and the secretary of the Board, provided that the signature of the chairman may be his facsimile signature. Coupons on all bonds shall bear the facsimile signatures of the chairman and the secretary. Bonds may be made registrable as to principal only on the books of the treasurer but coupons shall remain transferable by delivery merely notwithstanding any such registration. The bonds shall bear interest at a rate or rates of not more than the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, and shall mature within 40 years from the date of issuance, and may be made callable on any interest payment date at par and accrued interest, after notice has been given, at the time and in the manner and at such premium as may be provided in the bond resolution. The proceeds of the sale of said bonds shall be received by the treasurer of the Authority and expended by the Board for the purpose or purposes provided in the bond resolution.
     Bonds may be sold upon such terms and in such manner as may be designated by the Authority provided that no sale shall be made at less than par and accrued interest and further provided that the principal of and interest on any such bonds shall be made payable at such bank or banks as may be designated by the Authority.
     No bonds, other than revenue bonds issued pursuant to Section 205-35, shall be issued by the Authority until the proposition to issue the same has been submitted to and approved by a majority of the voters residing in the City of Peoria voting upon the proposition at an election in accordance with the general election law. The Authority may by resolution order such proposition submitted at a regular election in accordance with the general election law, whereupon the recording officer shall certify the resolution and the proposition to the proper election officials for submission.

     If a majority of the votes cast on the proposition are in the affirmative, the Authority may levy and collect annually a sum sufficient to pay for the annual principal and interest charges on such bonds; provided, that such tax levy shall be reduced by a sum equal to such grants or matching grants as the Authority shall receive, in any year, for this purpose.
     Such taxes proposed by the Authority to be levied upon the taxable property within the City of Peoria shall be levied in the ordinance providing for the issuance of the bonds. Within 10 days after its adoption, the ordinance shall be published at least once in a newspaper published and having a general circulation within the City of Peoria. After it has been so published, a certified copy of the ordinance shall be filed with the county clerk and shall constitute the authority for the county clerk annually to extend and collect the taxes necessary to pay the principal of and the interest on the bonds so issued.
