To carry out the legislative intent of those statutes contained in Oregon Revised Statutes requiring the county assessor, county treasurer or county tax collector to distribute moneys in the proportion that the rate percent of levy for each taxing unit bears to the total rate percent of levy of all units as shown on the tax roll for the fiscal year, the rates to be used for such apportionment shall be those specified in ORS 310.090 which are the computed rates necessary to raise the amounts required by ORS 311.105 (1)(c) for each district shown in the certificate filed with the tax collector under ORS 311.115 for such year.
