(A) After determining the estimated cost and the proportion thereof to be defrayed by the city at large, the Commission may order any public improvement, not included in the current year’s construction program, to be made or constructed, in any case when the same has been petitioned for by all of the owners of property within the district to be affected or which shall constitute a special assessment district for the payment of the cost of such improvement; provided that, prior to the commencement of work on the improvement petitioned for, 100% of the total estimated cost and expense of such improvement according to the estimates of the cost thereof and the special assessment roll based thereon, shall have been deposited with the City Treasurer by the property owners, within the district to be affected or constituting such special assessment district.
(B) In all cases where the total cost of any improvement has been deposited with the City Treasurer prior to commencement of work thereon, the assessment roll and each assessment appearing thereon shall immediately, upon confirmation of such roll, be marked paid.
(C) In doing any work, authorized and financed under the provisions of this section, the City Clerk shall keep an accurate record of the cost and expense thereof, and, upon completion of the work, shall report the same to the Commission which shall, thereupon, authorize and direct that the amount, if any, of such money, so deposited with the City Treasurer, which is in excess of the actual cost and expense of the improvement made, shall be repaid by the City Treasurer to those persons making such deposit, pro rata according to the several amounts deposited by them.
(D) The Commission shall report to the City Treasurer the city’s share, if any, of the cost and expense of such improvements, as determined by the Commission under the provisions of Chapter 33 (Special Assessments), and shall direct that repayment of said city’s share shall be made in one lump sum, or in five equal annual installments to the person or persons making such deposits. Such lump sum payments or the first of such installments shall be paid on or before the ninetieth day of the fiscal year following the completion of the work.
