Section 55 ILCS 90/30 - Ordinance adopted after public hearing(a) At any time within 30 days of the final adjournment of the public hearing, a county may, by ordinance, approve the economic development plan, establish the economic development project area, and authorize tax increment allocation financing for the economic development project area. Any ordinance adopted that approves the economic development plan shall contain findings (i) that the economic development project is reasonably expected to create or retain not fewer than 1,000 full-time equivalent jobs within a stated period after the completion of the proposed economic development project (the period being reasonable in light of the nature, type, and size of the proposed project), (ii) that private investment in an amount not less than $100,000,000 is reasonably expected to occur in the economic development project area, (iii) that the economic development project will encourage the increase of commerce and industry within the State, thereby reducing the evils attendant upon unemployment and increasing opportunities for personal income, and (iv) that the economic development project will increase or maintain the property, sales, and income tax bases of the county and of the State. Any ordinance adopted that establishes an economic development project area shall contain the boundaries of the area by legal description and, where possible, by street location. Any ordinance adopted that authorizes tax increment allocation financing shall provide that the ad valorem taxes, if any, arising from the levies upon taxable real property in the economic development project area by taxing districts and tax rates determined in the manner provided in subsection (b) of Section 45 each year after the effective date of the ordinance until economic development project costs and all county obligations financing economic development project costs incurred under this Act have been paid shall be divided as follows: (1) That portion of taxes levied upon each taxable lot, block, tract, or parcel of real property that is attributable to the lower of the current equalized assessed value or the initial equalized assessed value of each taxable lot, block, tract, or parcel of real property in the economic development project area shall be allocated to (and when collected shall be paid by the county collector to) the respective affected taxing districts in the manner required by law in the absence of the adoption of tax increment allocation financing.(2) That portion, if any, of the taxes that is attributable to the increase in the current equalized assessed valuation of each taxable lot, block, tract, or parcel of real property in the economic development project area over and above the initial equalized assessed value of each property in the economic development project area shall be allocated to (and when collected shall be paid to) the county treasurer, who shall deposit the taxes into a special fund called the special tax allocation fund of the county for the purpose of paying economic development project costs and obligations incurred in the payment of those costs.(b) In adopting an ordinance or ordinances under this Section, the county shall consider (i) whether, without public intervention, the economic development project area would not otherwise benefit from private investment offering substantial employment opportunities and economic growth and (ii) the impact on the revenues of the affected taxing districts of the use of tax increment allocation financing for the proposed economic development project.
