If a majority of all votes cast at the election are in favor of the tax levy for a municipal coliseum, the corporate authorities, in the next annual tax levy, shall include a tax not to exceed .25% of the value, as equalized or assessed by the Department of Revenue, on all the taxable property of the municipality for the establishment of a municipal coliseum in the municipality, and thereafter may annually levy a tax not to exceed .05% of the value, as equalized or assessed by the Department of Revenue, on all the taxable property of the municipality, for the maintenance thereof and for the payment for the use of any money loaned or advanced to the municipality for the purpose of buying a site and building the municipal coliseum, and for the repayment of any money so loaned or advanced. Payment for the use of money so loaned or advanced shall be in such form and manner as the board of directors may determine, and the amount so paid shall not exceed 5% annually on any money so loaned or advanced. The corporate authorities of such a municipality, when real estate owned by the municipality is not necessary for any other municipal purpose, may authorize the use of the real estate for the municipal coliseum.
     The foregoing limitations upon tax rates may be increased or decreased according to the referendum provisions of the General Revenue Law of Illinois.
