Oregon Revised Statutes Public Health and Safety § 457.450

(2) When the principal and interest on the maximum indebtedness of an urban renewal plan to which the portion of taxes is irrevocably pledged for payment under ORS 457.435 or 457.440 is fully paid, or it is found that deposits in the special fund are sufficient to fully pay principal and interest on the maximum indebtedness either through direct payment of the indebtedness or by payment of principal and interest on bonds or notes issued to finance the indebtedness, the agency shall notify the assessor of that fact.

(3) All moneys remaining unexpended from the special fund provided for in ORS 457.435 or 457.440, after payment of all the principal and interest on indebtedness is provided for, shall be turned over to the county treasurer by the agency and prorated by the treasurer back to the taxing districts in which the area, or part thereof, is located, in proportion to the amount of money in the fund attributable to each taxing district for the last fiscal year in which tax levy moneys were paid into the special fund of the agency under ORS 457.435 or 457.440.
