The following terms as used in this Law shall have the following meanings:
"Blighted area" means an area that is a blighted area which, by reason of the predominance of defective, non-existent, or inadequate street layout, unsanitary or unsafe conditions, deterioration of site improvements, improper subdivision or obsolete platting, or the existence of conditions which endanger life or property by fire or other causes, or any combination of those factors, retards the provision of housing accommodations or constitutes an economic or social liability, an economic underutilization of the area, or a menace to the public health, safety, morals, or welfare.
"Business district" means a contiguous area which includes only parcels of real property directly and substantially benefited by the proposed business district plan. A business district may, but need not be, a blighted area, but no municipality shall be authorized to impose taxes pursuant to subsection (10) or (11) of Section 11-74.3-3 in a business district which has not been determined by ordinance to be a blighted area under this Law. For purposes of this Division, parcels are contiguous if they touch or join one another in a reasonably substantial physical sense or if they meet the criteria for annexation to a municipality under Section 7-1-1 of this Code. The changes made by this amendatory Act of the 102nd General Assembly, are declarative of existing law and shall be applied retroactively when substantively applicable, including all pending actions without regard to when the cause of action accrued; however, this amendatory Act of the 102nd General Assembly does not affect the rights of any party that is subject to a final judgment entered pursuant to the September 23, 2021 opinion of the Illinois Supreme Court in Board of Education of Richland School District 88A v. City of Crest Hill, 2021 IL 126444.

Each business district plan shall set forth in writing: (i) a specific description of the boundaries of the proposed business district, including a map illustrating the boundaries; (ii) a general description of each project proposed to be undertaken within the business district, including a description of the approximate location of each project and a description of any developer, user, or tenant of any property to be located or improved within the proposed business district; (iii) the name of the proposed business district; (iv) the estimated business district project costs; (v) the anticipated source of funds to pay business district project costs; (vi) the anticipated type and terms of any obligations to be issued; and (vii) the rate of any tax to be imposed pursuant to subsection (10) or (11) of Section 11-74.3-3 and the period of time for which the tax shall be imposed.
"Business district project costs" shall mean and include the sum total of all costs incurred by a municipality, other governmental entity, or nongovernmental person in connection with a business district, in the furtherance of a business district plan, including, without limitation, the following:
"Business district tax allocation fund" means the special fund to be established by a municipality for a business district as provided in Section 11-74.3-6.
