Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

    (35 ILCS 200/11-175)
    Sec. 11-175. Legislative findings. The General Assembly finds that it is the policy of the State to ensure and encourage the availability of means for the safe collection, treatment, and disposal of domestic, commercial, and industrial sewage and waste for our cities, villages, towns, and rural residents and that it has become increasingly difficult and cost prohibitive for smaller cities, towns, and villages to construct, maintain, or operate, to current standards, wastewater facilities. The General Assembly further finds that regional facilities capable of serving several cities, villages, towns, municipal joint sewage treatment agencies, municipal sewer commissions, sanitary districts, and rural wastewater companies offer a viable economic solution to this concern. For these reasons, the General Assembly declares it to be the policy of the State to encourage the construction and operation of regional wastewater facilities capable of providing for the safe collection, treatment, and disposal of domestic, commercial, and industrial sewage and waste for cities, villages, towns, municipal joint sewage treatment agencies, municipal sewer commissions, sanitary districts, and rural wastewater companies thereby relieving the burden on those entities and their citizens from constructing and maintaining their own individual wastewater facilities.

"NOTICE TO TAXPAYERS
    Median Level of Assessment--(insert here the median level of assessment for the assessment district)
    Your property is to be assessed at the above listed median level of assessment for the assessment district. You may check the accuracy of your assessment by dividing your assessment by the median level of assessment. The resulting value should equal the estimated fair cash value of your property. If the resulting value is greater than the estimated fair cash value of your property, you may be over-assessed. If the resulting value is less than the fair cash value of your property, you may be under-assessed. You may appeal your assessment to the Board of Review."
    The notice published under this Section shall also include the following:
        (1) A statement advising the taxpayer that
    
assessments of property, other than farm land and coal, are required by law to be assessed at 33 1/3% of fair market value.

and, if one exists, the website address of the assessor.
        (3) A statement advising the taxpayer of the steps to
    
follow if the taxpayer believes the full fair market value of the property is incorrect or believes the assessment is not uniform with other comparable properties in the same neighborhood. The statement shall also (i) advise all taxpayers to contact the township assessor's office, in those counties under township organization, first to review the assessment, (ii) advise all taxpayers to file an appeal with the board of review if not satisfied with the assessor review, and (iii) give the phone number to call for a copy of the board of review rules; if the Board of Review maintains a web site, the notice must also include the address of the website where the Board of Review rules can be viewed.
        (4) A statement advising the taxpayer that there is a
    
deadline date for filing an appeal with the board of review and indicating that deadline date (30 days following the scheduled publication date).
        (5) A brief explanation of the relationship between
    
the assessment and the tax bill.
        (6) In bold type, a notice of possible eligibility
    
for the various homestead exemptions as provided in Section 15-165 through Section 15-175 and Section 15-180.
