Whenever, pursuant to this chapter, the commission shall function in any municipality, such municipality may with the approval in writing of such commission extend the period theretofore granted for the payment of assessments for benefits for local improvements, by granting to the owner of the property so assessed the privilege of paying in five additional equal annual installments the amount of all such assessments confirmed and due and payable, by reason of a default or otherwise, as of the date of the resolution hereinafter mentioned, and of the interest thereon and penalties and other charges relating to such assessments accrued to such date. Such action shall be taken by resolution of the governing body of the municipality describing with clearness sufficient for identification the property so affected, the amount of such assessments, interest, penalties and other charges, and the annual dates when the installments of such amount shall thereafter be due and payable. Such resolution shall not take effect until approved in writing by the commission after public notice published in a newspaper having a substantial circulation in the municipality. There need not be a separate resolution for each property or property owner.
