The purpose of this section of the code is to assist in determining which road authorities participate in land use decisions, and to implement Section 660-012-0045(2)(e) of the State Transportation Planning Rule that requires the city to adopt a process to apply conditions to development proposals in order to minimize impacts and protect transportation facilities. This chapter establishes the standards for when a proposal must be reviewed for potential traffic impacts; when a traffic impact analysis must be submitted with a development application in order to determine whether conditions are needed to minimize impacts to and protect transportation facilities; what must be in a traffic impact analysis; and who is qualified to prepare the study.
(A) When a traffic impact study is required. The city or other road authority with jurisdiction may require a Traffic Impact Analysis (TIA) as part of an application for development, a change in use or a change in access. A TIA shall be required when a land use application involves one or more of the following actions:
(1) A change in zoning or a plan amendment designation;
(2) Any proposed development or land use action that a road authority states may have operational or safety concerns along its facility(ies);
(3) An increase in site traffic volume generation by 300 Average Daily Trips (ADT) or more;
(4) An increase in peak hour volume of a particular movement to and from the state highway by 20% or more; or
(5) An increase in use of adjacent streets by vehicles exceeding the 20,000-pound gross vehicle weights by 10 vehicles or more per day;
(6) The location of the access driveway does not meet minimum sight distance requirements, or is located where vehicles entering or leaving the property are restricted, or such vehicles queue or hesitate on the state highway creating a safety hazard; or
(7) A change in internal traffic patterns that may cause safety problems, such as back up onto a street or greater potential for traffic accidents.
(B) Traffic impact study preparation. A traffic impact analysis shall be prepared by a professional engineer in accordance with the requirements of the road authority. If the road authority is the Oregon Department of Transportation (ODOT), consult ODOT's regional development review planner and OAR 734-051-180.
