in effect(a) No city or town shall proceed with any reassessment or supplemental assessment unless the ordinance ordering it is passed by the governing body within:
(i) Three (3) years from the time the original assessment for the improvement was held to be invalid, insufficient or for any cause set aside, in whole or in part, or held void or its enforcement denied directly or indirectly by the courts; or
(ii) In the case of supplemental assessments within three (3) years from the time it was determined that the total amount of the valid assessments levied and assessed on account of any improvement was insufficient to pay the whole or that portion of the cost and expense to be paid by special assessment.
(b) If the amount collected by assessment is insufficient to pay the cost of the improvement, the governing body may authorize the payment of the deficit out of the permanent improvement fund.
