The board of county commissioners must levy upon taxable property within the district a tax at a rate not greater than sufficient to raise the amount determined by the board of trustees as approved by the board of county commissioners, as necessary for the operation of the district for the ensuing year. In no event shall such tax exceed one tenth percent (.1%) of the market value for assessment purposes on all taxable property within the district. All taxes thus levied shall be collected in the same manner as other taxes and deposited to the credit of the abatement district and shall be used for no other purposes. Such funds may be withdrawn from the county treasury and upon warrant of the board of trustees of the abatement district, signed by the president of the board and countersigned by its secretary, for the activities of the abatement district.
