The City Manager shall, after the completion of each local public improvement, compile the actual cost thereof and certify the same to the Council. When any special assessment roll shall prove insufficient to meet the cost of the improvement for which it was made, the Council may make an additional pro rata assessment; provided, however, that, no such additional pro rata assessment shall exceed 15% of the original assessment. If the amount of the special assessment roll for any local public improvement as confirmed by the Council proves larger than the actual cost thereof as compiled by the City Manager and certified to the Council, the Council shall make a refund thereof in accordance with § 9.4 of the City Charter, said refund to be made to the owner of the property as shown by the current tax rolls of the city on the date that the Council orders the refund.
