(35 ILCS 200/10-100)
Liability for prior year's taxes.
The valuation determined
under Section 10-90 shall be used for each year for which application is made
and approved under Section 10-95. When any portion of the land is no longer
used for airport purposes, the person liable for taxes on that portion of the
land shall notify the chief county assessment officer, in writing, of that
fact, and shall pay to the county treasurer, by the following September 1, the
difference between the taxes paid in each of the 3 preceding years as based on
a valuation under Section 10-90 and what those taxes for each of those years
would have been when based on the valuation as otherwise permitted by law,
together with 5% interest. If this difference is not paid by the following
September 1, the amount of that difference shall be considered as delinquent
taxes under this Code.
