(a) On or before the first Monday in October of each year, the board of directors shall estimate the amount necessary for the ensuing calendar year for operation and maintenance of the works of improvement provided for in the improvement plan and shall submit the estimate to the chancery court which approved the plan, with a request that a tax levy be made for the estimated amount.
(b) If the court finds the estimated amount to be fair and reasonable, it shall enter an order, which shall have the force and effect of a judgment, providing that there shall be levied against the benefited land within the project area a tax sufficient to pay the estimated cost of operation and maintenance. This tax shall be a charge against the benefited land in the proportion to the amount of the assessment of benefits on the land.
