Should any special assessment prove insufficient to pay for the improvement and related costs of the project for which it was levied, or to pay the principal and interest on bonds issued in anticipation of such special assessment roll, the Council may make additional pro rata assessments. Should any special assessment prove larger than necessary by less than 5%, the Council may place the excess in the General Fund of the city; if more than 5%, the entire excess shall be refunded pro rata to the owners of the property assessed, as shown by the current assessment roll of the city, and to the city to the extent it has been assessed.
