The corporate authorities of any such sanitary district may by ordinance establish a fund to be known as the "stormwater working cash fund", which shall be maintained and administered in the manner provided by this Act for the purpose of enabling the corporate authorities to have in the treasury at all times sufficient money to meet demands for ordinary and necessary expenditures for stormwater management purposes as defined in Section 7h of this Act.
To create the stormwater working cash fund, the corporate authorities may transfer funds allowed to be transferred under this Act into the stormwater working cash fund, in an amount not to exceed 100% of the amount produced by multiplying the maximum tax rate permitted under this Act for stormwater purposes by the last known assessed valuation of all taxable property within the territorial boundaries of the sanitary district, as equalized and determined for State and local taxes. All such moneys, when received by the treasurer of the district, shall be set apart in the stormwater working cash fund.
The moneys in the stormwater working cash fund shall not be regarded as current assets available for appropriation and shall not be appropriated by the corporate authorities in the annual sanitary district budget.
In order to provide moneys with which to meet ordinary and necessary disbursements for salaries and other stormwater purposes, moneys in the stormwater working cash fund may be transferred, in whole or in part, to the stormwater fund of the sanitary district and so disbursed therefrom in anticipation of the collection of any taxes lawfully levied for stormwater purposes. Moneys shall be transferred from the stormwater working cash fund to the stormwater fund only upon the authority of the corporate authorities, which shall by resolution direct the treasurer of the sanitary district to make transfers. The resolution shall set forth (1) the entire amount of real estate taxes extended or estimated to be extended from which the stormwater working cash fund will be reimbursed, and (2) the aggregate amount of moneys theretofore transferred from the stormwater working cash fund to the stormwater fund in anticipation of the collection of such taxes. The amount that the resolution directs the treasurer of the sanitary district to transfer in anticipation of the collection of taxes levied, when added to the aggregate amount of any such transfers theretofore made, shall not exceed the aggregate of 100% of the actual or estimated amount of such taxes extended or to be extended.
Upon the receipt by the treasurer of the sanitary district of any taxes in anticipation of the collection of which moneys of the stormwater working cash fund have been so transferred for disbursement, that fund shall immediately be reimbursed from those taxes until the full amount so transferred has been retransferred to the fund. If the taxes in anticipation of the collection of which such a transfer was made are not collected in sufficient amounts to effect a complete reimbursement of the stormwater working cash fund within the second budget year following the year in which the transfer was made, the deficiencies between the amounts so transferred and the amounts repaid shall be general obligations of the stormwater fund until repaid from taxes in anticipation of which such transfers were made or from appropriations which may be made in annual sanitary district budgets of sums of money to apply on such general obligations.
Any member of the board of commissioners of the sanitary district, any officer thereof, and any other person holding any other position of trust or employment under that board who is guilty of the willful violation of any of the provisions of this Section commits a business offense and shall be fined an amount not exceeding $10,000 and shall forfeit the right to his or her office, trust, or employment and be removed therefrom. Any such member, officer, or person shall be liable for any sum that he or she may cause to be unlawfully diverted from the stormwater working cash fund or otherwise improperly used, to be recovered by the corporate authorities of the sanitary district or by any taxpayer in the name and for the benefit of the board of commissioners in an appropriate civil action. A taxpayer so suing shall file a bond for, and shall be liable for, all costs taxed against the board of commissioners in the suit. Nothing herein shall bar any other remedies.
