The county clerk of the county in which the municipality specified in Section 11-112-1 is located shall extend each year the taxes specified in Section 11-112-1, when the ordinance making the levy of the tax is certified to him. The tax shall be extended at the rate fixed in the ordinance, not exceeding .1666% for a period not exceeding 7 years. The county clerk shall extend the tax in a separate column designated the "Seven Year Levee Tax."
The collector of state and county taxes, when he receives the money collected from this levee tax, shall pay it to the municipal treasurer, every 2 weeks, informing the treasurer that this money is from the 7 year levee tax; and he shall take the treasurer's receipt for the money as 7 year levee tax paid over.
The municipal treasurer shall receive the money so paid over by the collector and shall pay the money out as rapidly as possible on warrants issued on the 7 year levee tax only, so long as such warrants remain unpaid.
This tax shall be levied in addition to taxes for general purposes authorized by Section 8-3-1.
The foregoing limitation upon tax rate may be increased or decreased according to the referendum provisions of the General Revenue Law of Illinois.
