Oregon Revised Statutes Cities § 223.270

(1) If the owner neglects or refuses to pay installments under ORS 223.265 as they become due and payable for a period of one year, then the governing body of the local government may, by reason of the neglect or refusal to pay the installments, and while the neglect and refusal to pay continues, pass a resolution:

(2) The governing body may then proceed at once to collect all unpaid installments and to enforce collection thereof, with all unpaid late payment penalties and charges added thereto, in the same manner in which delinquent property taxes are collected under applicable law or, in the case of a city, in the same manner as street and sewer assessments are collected pursuant to the terms of the city charter.
