Sec. 39. (a) This section applies only to departments in a county having a population of:
(1) more than four hundred thousand (400,000) and less than seven hundred thousand (700,000); or
(2) more than two hundred fifty thousand (250,000) and less than three hundred thousand (300,000).
(b) The board may secure temporary loans in anticipation of revenues of the district actually levied and in the course of collection for the fiscal year in which loans are made. The loans must be authorized by a resolution of the board, and the securities evidencing them shall be issued and sold in the same manner as tax anticipation warrants by second class cities in anticipation of property tax revenues as provided in IC 36-4-6-20. The temporary loans shall be evidenced by time warrants of the district in terms designating the nature of the consideration, the time or times payable, the funds and revenues in anticipation of which the warrants are issued and out of which they are payable, and the place where they are payable upon presentation on or after the date of maturity. The interest accruing on the warrants to date of maturity shall be included in their face value. The resolution authorizing the issue of the temporary loans must appropriate and pledge a sufficient amount of the current revenues in anticipation of which the warrants are issued for their payment.
