Section 257.350 - Organization tax - pledge of anticipated revenues1. As soon as any district is organized under this chapter, and a board of trustees is selected and qualified, all tangible property in the district may be taxed not to exceed one mill on each dollar of the assessed valuation thereof per annum for a period not to exceed three years. The tax moneys shall be used for paying expenses of organization, for preliminary surveys and plans, and for other incidental expenses which may be necessary to the proper establishment of the district. Such organization tax shall be certified by the board of trustees to the various county commissions of the various counties and by them extended upon the tax books and certified to the respective collectors of revenue of their counties. If the items of expense have already been paid in whole or in part from other sources, they may be repaid from the receipts of the levy. The collection of the tax levy shall conform in all matters to the collection of taxes and assessments for the district outlined in this chapter and the same provisions concerning the nonpayment of taxes shall apply.2. In order to facilitate the preliminary work and establishment of the district, the board of trustees may borrow money, authorized by a resolution therefor, at a rate of interest not exceeding six percent per annum, may issue and sell or pay to contractors or others, negotiable evidence of debt (herein called warrants) therefor signed by the president and secretary of the board of trustees and may pledge (after it has been levied) the organization tax of not exceeding one mill on each one dollar of assessed valuation per annum for the repayment thereof. If any warrant issued by the board of trustees is presented for payment and is not paid for want of funds in the treasury that fact with the date of refusal shall be endorsed on the back of the warrant and the warrant shall thereafter draw interest at the rate of six percent until such time as there is money on hand sufficient to pay the amount of the warrant with interest.
