(1) At the same time that the assessment of benefits is equalized or at any time thereafter, the board shall enter upon its records an order, which shall have all the force of a judgment, providing that there is levied upon the real property of the district a tax sufficient to pay the estimated cost of the improvement with ten percent (10%) added for unforeseen contingencies.
(2) The tax is to be paid by the real property owners in the district in the proportion to the amount of the assessment of benefits thereon and is to be paid in annual installments, as provided in the order.
(3) The tax so levied shall be a lien upon all the real property in the district from the time it is levied, shall be entitled to preference over all demands, executions, encumbrances, or liens whenever created, and shall continue until the assessment, with any penalty costs that may accrue thereon, shall have been paid. Provided, however, with the prior written approval of the board, the county clerk shall release from the lien for the assessment and tax any lot, block, or tract with respect to which the assessment and tax shall have been paid or prepaid.
(4) Promptly after entry of an order levying the tax, the board shall publish at least one (1) time in some newspaper having general circulation in the municipality a notice setting forth the order of levy and warning all persons affected by it that the order shall become final unless suit is brought to contest the order within thirty (30) days of the date of first publication of the notice; and
(5) No property owner shall be barred from contest of the levy within the thirty-days' publication period.
(6) The remedy against such levy of taxes shall be by suit in chancery.
(7) The suit must be brought within thirty (30) days from the time of notice that the levy was made, and, on the appeal, the presumption shall be in favor of the legality of the tax.
