Should any special assessment prove insufficient to pay for the improvement or work for which it was levied, and the expenses incident thereto, including all interest still to accrue upon any and all bonds issued in anticipation of the collection of such special assessments, the City Council may, in the manner and within the limitations prescribed herein for such assessments, make an additional pro rata assessment to supply the deficiency, and in case a larger amount shall have been collected than was necessary, the excess shall be refunded ratably to those by whom it was paid.
