If the property owner fails to appeal to the city council within the allotted time or if the council finds that the condition of the property noted by the city engineer constitutes a public nuisance and that the property owner should be responsible for the cost of removing such nuisance, the full cost of abating the public nuisance shall be made a special assessment against the concerned parcel or parcels. The precise cost of the removal shall be announced and confirmed by the city council at a duly noticed hearing of the council as soon as the final costs have been ascertained. The assessment may be collected at the same time and in the same manner as ordinary municipal taxes are collected and shall be subjected to the same penalties and the same procedure and sale in case of delinquency as provided for ordinary municipal taxes. All laws applicable to the levy, collection and enforcement of municipal taxes shall be applicable to such special assessment. (Prior code § 5220.11)
