Or. Admin. R. 350-010-0050 - Natural and Human Management Processes Do Not Affect Urban Area Boundaries

(1) The location of an urban area boundary does not shift in response to natural processes that occur over a long period of time, such as accretion and reliction of rivers and streams or ordinary high water, or as a result of major sudden event, such as an avulsion, flooding, landslide, or earthquake. The urban area boundary remains at the location described prior to the event.
(2) The location of an urban area boundary does not shift in response to management of the normal pool elevation behind Bonneville and The Dalles dams. The normal pool elevation is as defined by dam operations on November 17, 1986.
(3) The location of an urban area boundary does not shift in response to relocation or realignment of linear features, including but not limited to roads and highways, railroads, pipelines, or powerlines, or their associated rights-of-way or easements. A Legal Description that uses a linear feature means the linear feature as it existed on November 17, 1986, or as otherwise noted in the Legal Description.
(4) The location of an urban area boundary does not shift in response to changes in land management boundaries, including, but not limited to, municipal boundaries and approved urban growth boundaries. A Legal Description that refers to a land management boundary means the land management boundary as it existed on November 17, 1986, or as otherwise described in the Legal Description.
