The multi-township or township board of trustees shall adopt a budget and appropriation ordinance in accordance with the Illinois Municipal Budget Law.
The multi-township board must, at least 30 days before the public hearing required by Section 3 of the Illinois Municipal Budget Law, prepare or cause to be prepared a tentative budget and appropriation ordinance and file the ordinance with the township clerks of the townships comprising the multi-township assessment district. The township clerks must make the tentative budget and appropriation ordinance available for public inspection for at least 30 days before final action on the ordinance. The required public hearing must be held on or before the last day of the first quarter of the fiscal year before the board. Notice of the hearing must be given by publication in a newspaper published in the multi-township assessment district at least 30 days before the time of the hearing. If there is no newspaper published in the multi-township assessment district, notice of the public hearing may be given by posting notices in 5 of the most public places in each township comprising the multi-township assessment district. It is the duty of the township clerks to arrange for the public hearing. The board at the public hearing may adopt all or part of the tentative budget and appropriation ordinance, as the board deems necessary.
The multi-township or township board of trustees shall determine the amount required and permitted by law to finance the operations of the office of the multi-township or township assessor. The board of trustees shall certify that amount in a levy to the county clerk in the manner provided in Section 2-20.
