When any municipality shall have levied assessments against real property for the purpose of paying for any permanent improvement to streets and sidewalks of any type mentioned in Section 5-21-620, the municipal council may by ordinance direct that bonds of the municipality, to be known as paving bonds, be issued in anticipation of the collection of such assessments. The amount of the bonds to be issued may equal but shall not exceed the amount of the unmatured assessments remaining uncollected at the time of the adoption of the ordinance authorizing their issuance. A single issue of paving bonds may be authorized and issued in anticipation of the collection of two or more separate assessments.
