If the bill is not paid to the City Administrator within 30 days from the date issued, the listed total of unpaid charges for the clearing of snow and loose or melting ice from public sidewalks shall be charged along with all other charges for current services to be assessed under M.S. § 429.101, as it may be amended from time to time. If no objection is made or if the Council shall find that the work was properly done, then the amount of the cost shall be reported to the County Auditor as in the case of other special assessments, and the Auditor shall cause the cost to be assessed, levied and collected in one payment, provided, that within 30 days after the Commissioner’s report is made to the City Council, the amount of the cost may be paid to the city.
