660-038-0130 Adjust Employment Buildable Land Inventory to Account for Constrained Lands A city must adjust the employment buildable lands inventory determined under OAR 660-038-0120 to account for constrained lands using this rule. (1) The city must identify the following physical constraints on employment land inventoried under OAR 660-038-0120: (a) Floodways and water bodies. For the purpose of this subsection, “water bodies” includes: (A) Rivers; and (B) Lakes, ponds, sloughs, and coastal waters at least one-half acre in size; (b) Other lands within the Special Flood Hazard Area as identified on the applicable Flood Insurance Rate Map; (c) Lands within the tsunami inundation zone established pursuant to ORS 455.446; (d) Contiguous lands planned and zoned for commercial use of at least one acre with slopes that are greater than 25 percent. For purposes of this rule, slope shall be measured as the increase in elevation divided by the horizontal distance at maximum 10-foot contour intervals; (e) Contiguous lands planned and zoned for industrial use of at least one acre with slopes that are greater than 10 percent. For purposes of this rule, slope shall be measured as the increase in elevation divided by the horizontal distance at maximum 10-foot contour intervals; (f) Lands subject to development restrictions as a result of acknowledged comprehensive plan or land use regulations to implement Statewide Planning Goals 5, 6, or 7, and (f) Lands subject to development prohibitions, natural resource protections, or both, in an acknowledged comprehensive plan or land use regulations that implement Statewide Planning Goals 15, 16, 17, or 18. (2) For lands identified in section (1), the city may reduce the estimated development capacity by the following factors in terms of acreage: (a) For lands within floodways and water bodies: a 100 percent reduction. (b) For other lands within the Special Flood Hazard Area (SFHA) as identified on the applicable Flood Insurance Rate Map (FIRM), either (at the city’s option): (A) A 50 percent reduction, or (B) A reduction to the levels required by the acknowledged comprehensive plan or land use regulations. (c) For lands within the tsunami inundation zone: no reduction unless the acknowledged comprehensive plan or land use regulations applicable to such areas prohibits or reduces allowed development, in which case the reduction shall be based upon the maximum density allowed by the acknowledged comprehensive plan or land use regulations. (d) For lands designated for commercial use, contiguous lands of at least one acre with slope greater than 25 percent: a 100 percent reduction, provided that if such land includes slopes less than 25 percent, the reduction applies only to those areas with slopes greater than 25 percent. Slope shall be measured as the increase in elevation divided by the horizontal distance at maximum ten-foot contour intervals; (e) For lands designated for industrial use, contiguous lands of at least one acre with slope greater than 10 percent: a 100 percent reduction, provided that a lot or parcel with slopes greater than 10 percent that has at least five contiguous acres with slopes less than 10 percent, this authorized reduction does not apply to those areas. (f) For lands subject to restrictions in density or location of development in an acknowledged comprehensive plan or land use regulations developed pursuant to Statewide Planning Goals 5, 6, or 7: a reduction to the maximum level of development authorized by the acknowledged comprehensive plan or land use regulations. (g) For lands subject to development prohibitions, natural resource protections, or both, in an acknowledged comprehensive plan or land use regulations that implements Statewide Planning Goals 15, 16, 17, or 18: a reduction to the maximum level of development authorized by the acknowledged comprehensive plan or land use regulations. (3) The amount of buildable land in the UGB designated for commercial and industrial uses is that amount determined in OAR 660-038-0120 reduced by the constraints determined under section (2) of this rule.
