Oregon Revised Statutes Public Health and Safety § 457.105

In addition to the approval of a plan by the governing body of the municipality under ORS 457.095, when any portion of the area of a proposed urban renewal plan extends beyond the boundaries of the municipality into any other municipality and, in the case of a proposed plan by a county agency, when any portion of such area is within the boundaries of a city, the governing body of the other municipality may approve the plan and may do so by resolution, rather than by ordinance. A proposed plan for an urban renewal area which is wholly within the boundaries of a city, or which is wholly within the boundaries of a county and does not include any area within the boundaries of a city, must be approved only by the governing body of the municipality in accordance with ORS 457.095.
