Section 308.565 - Apportionment of assessment among counties(1) For the purpose of determining the amount of the assessment of any centrally assessed company that is to be apportioned to those counties in this state in which the rail lines of the company are located, the Department of Revenue shall multiply the values per mile, as ascertained pursuant to ORS 308.570, of main and branch lines by the number of miles of main and branch lines in each county, including miles of main tracks, spurs, yard tracks and sidetracks, as reported by the company or as otherwise determined by the department.(2) The department shall apportion values distributed over wire, pipe or pole lines or operational routes to those counties in which the lines or routes are located by multiplying the rate per mile in each case, determined pursuant to ORS 308.575, by the number of miles of the wire, pipe or pole lines or operational routes in each county.(3) If the property of any company assessable under ORS 308.505 to 308.674 is of such a character that its value cannot reasonably be apportioned on the basis of rail, wire, pipe, pole line or operational route mileage, the department may adopt any other method or basis of apportionment to each county in which the property is located that the department determines to be feasible and proper.(4) As determined by the department, values of electric power plants and water powers, connected with or used in the operation and business of any company, assessable under ORS 308.505 to 308.674, may be apportioned to each county in which power plants and water powers are located in a manner the department deems reasonable and fair.(5) Assessments of the mobile property of air transportation companies shall be allocated and apportioned only to those counties in which the air transportation companies make service landings. For aircraft less than 75,000 pounds gross taxi weight, the department shall allocate and apportion to the counties 60 percent of the value which would otherwise be allocated and apportioned.(6)(a) Assessments of water transportation companies shall be allocated and apportioned to those counties in which such companies use or maintain ports or termini, including off-shore anchorages.(b) For purposes of ORS 308.505 to 308.674, the taxing districts to which assessments are apportioned by the county assessor shall be deemed to extend to the center of any river channel or to the ocean bar.Amended by 1957 c.711 §9; 1987 c.601 §2; 1997 c.154 §40; 2009 c. 128, § 8
