Current through Register Vol. 63, No. 10, October 1, 2024

Section 660-038-0160 - Establishment of Study Area to Evaluate Land for Inclusion in the UGB

Cities shall comply with this rule and OAR 660-038-0170 when determining which lands to include within the UGB in response to a deficit of land to meet long-term needs determined under OAR 660-038-0080, 660-038-0150, or both.

(1) The city shall determine which land to add to the UGB by evaluating alternative locations within a "study area" established pursuant to this rule. To establish the study area, the city must first identify a "preliminary study area" which shall not include land within a different UGB or the corporate limits of a city within a different UGB. The preliminary study area shall include:

(a) All lands in the city's acknowledged urban reserve, if any;

(b) All lands that are within the following distance from the acknowledged UGB, except as provided in subsection (d):

(A) For cities with a UGB population less than 10,000: one-half mile;

(B) For cities with a UGB population equal to or greater than 10,000: one mile;

(c) All exception areas contiguous to an exception area that includes land within the distance specified in subsection (b) and that are within the following distance from the acknowledged UGB:

(A) For cities with a UGB population less than 10,000: one mile;

(B) For cities with a UGB population equal to or greater than 10,000: one and one-half miles;

(d) At the discretion of the city, the preliminary study area may include land that is beyond the distance specified in subsections (b) and (c).

(2) The city may exclude land from the preliminary study area if it determines that any of the conditions in this section apply to the land:

(a) Based on the standards in section (5) of this rule, it is impracticable to provide necessary public facilities or services to the land;

(b) The land is subject to significant development hazards, due to a risk of:

(A) Landslides: The land consists of a landslide deposit or scarp flank that is described and mapped on the Statewide Landslide Information Database for Oregon (SLIDO) Release 3.2 Geodatabase published by the Oregon Department of Geology and Mineral Industries (DOGAMI) December 2014, provided that the deposit or scarp flank in the data source is mapped at a scale of 1:40,000 or finer. If the owner of a lot or parcel provides the city with a site-specific analysis by a certified engineering geologist demonstrating that development of the property would not be subject to significant landslide risk, the city may not exclude the lot or parcel under this paragraph;

(B) Flooding, including inundation during storm surges: the land is within the Special Flood Hazard Area (SFHA) identified on the applicable Flood Insurance Rate Map (FIRM);

(C) Tsunamis: the land is within a tsunami inundation zone established pursuant to ORS 455.446.

(c) The land consists of a significant scenic, natural, cultural or recreational resource described in this subsection:

(A) Land that is designated in an acknowledged comprehensive plan prior to initiation of the UGB amendment, or that is mapped on a published state or federal inventory at a scale sufficient to determine its location for purposes of this rule, as:

(i) Critical or essential habitat for a species listed by a state or federal agency as threatened or endangered;

(ii) Core habitat for Greater Sage Grouse; or

(iii) Migration corridors or big game winter range, except where located on lands designated as urban reserves or exception areas;

(B) Federal Wild and Scenic Rivers and State Scenic Waterways, including Related Adjacent Lands described by ORS 390.805, as mapped by the applicable state or federal agency responsible for that scenic program;

(C) Designated Natural Areas on the Oregon State Register of Natural Heritage Resources;

(D) Wellhead protection areas described under OAR 660-023-0140 and delineated on a local comprehensive plan;

(E) Aquatic areas subject to Statewide Planning Goal 16 that are in a Natural or Conservation management unit designated in an acknowledged comprehensive plan;

(F) Lands subject to acknowledged comprehensive plan or land use regulations that implement Statewide Planning Goal 17, Coastal Shoreland, Use Requirement 1;

(G) Lands subject to acknowledged comprehensive plan or land use regulations that implement Statewide Planning Goal 18, Implementation Requirement 2.

(d) The land is owned by the federal government and managed primarily for rural uses.

(3) After excluding land from the preliminary study area under section (2), the city must adjust the study area, if necessary, so that it includes an amount of land that is at least twice the amount of land needed to satisfy the combined need deficiency determined under OAR 660-038-0080 and 660-038-0150. Such adjustment shall be made by expanding the applicable distance specified under section (1) and applying section (2) to the expanded area.

(4) For purposes of evaluating the priority of land under OAR 660-038-0170, the "study area" shall consist of all land that remains in the preliminary study area described in section (1) of this rule after adjustments to the area based on sections (2) and (3).

(5) For purposes of subsection (2)(a), the city may consider it impracticable to provide necessary public facilities or services to the following lands:

(a) Contiguous areas of at least five acres where 75 percent or more of the land has a slope of 25 percent or greater; provided that contiguous areas 20 acres or more that are less than 25 percent slope may not be excluded under this subsection. Slope shall be measured as the increase in elevation divided by the horizontal distance at maximum ten-foot contour intervals;

(b) Lands requiring the construction of a new freeway interchange, overpass, underpass, or similar improvement to accommodate planned urban development providing such improvement is not currently identified in the Statewide Transportation Improvement Program (STIP) for construction within the planning period;

(c) Land that is isolated from existing service networks by physical, topographic, or other impediments to service provision such that it is impracticable to provide necessary facilities or services to the land within the planning period. The city's determination shall be based on an evaluation of:

(A) The likely amount of development that could occur on the land within the planning period;

(B) The likely cost of facilities and services; and,

(C) Any substantial evidence collected by or presented to the city regarding how similarly situated land in the region has, or has not, developed over time.

(d) As used in this section, "impediments to service provision" may include but are not limited to:

(A) Major rivers or other water bodies that would require new bridge crossings to serve planned urban development;

(B) Topographic features such as canyons or ridges with slopes exceeding 40 percent and vertical relief of greater than 80 feet;

(C) Freeways, rail lines, or other restricted access corridors that would require new grade separated crossings to serve planned urban development;

(D) Significant scenic, natural, cultural or recreational resources on an acknowledged plan inventory and subject protection measures under the plan or implementing regulations, or on a published state or federal inventory, that would prohibit or substantially impede the placement or construction of necessary public facilities and services.

(6) Land may not be excluded from the preliminary study area based on a finding of impracticability that is primarily a result of existing development patterns. However, a city may forecast development capacity for such land as provided in OAR 660-038-0170(1)(d).

(7) A city that has a population of 10,000 or more that evaluates or amends its UGB using a method described in this division, must notify districts and counties that have territory within the study area in the manner required by ORS 197A.315 and meet other applicable requirements in that statute.
