Sec. 16. (a) All or part of the necessary preliminary expenses that are incurred by a board and must be paid before the issuance and delivery of revenue bonds under this chapter may be paid in the manner provided by this section.
(b) The board may certify the items of expense to the fiscal officer of the unit, who shall immediately draw a warrant or warrants to be paid out of the unappropriated part of the general fund of the unit, without a special appropriation being made. If the unit has no unappropriated money in its general fund, the fiscal officer shall recommend to the fiscal body of the unit:
(1) the temporary transfer from other funds of a sufficient amount to meet the items of expense; or
(2) the making of a temporary loan for that purpose.
The fiscal body shall immediately make the transfer or authorize the temporary loan.
(c) The fund or funds from which the payments are made shall be fully reimbursed and repaid out of the first proceeds of the sale of revenue bonds, and before any other disbursements are made from those proceeds. The amount advanced to pay preliminary expenses is a first charge against the proceeds resulting from the sale of the revenue bonds until it has been repaid.
