The purpose of this section is to implement OAR 660-012-0045(2)(e), the State Transportation Planning Rule, requiring cities to adopt a development review process which minimizes transportation impacts and protects transportation facilities.
A.
Traffic Impact Analysis. The city shall require a traffic impact analysis (TIA) as part of an application for development, a change in use, or a change in access in the following situations:
1.
If the division application includes residential development, a TIA shall be required when the land use application involves one or more of the following actions:
a.
An increase in site traffic volume generation by 200 average daily trips or more; or
b.
An increase in peak hour volume of a particular movement to and from the state highway by 20 percent or more; or
c.
An increase in use of adjacent streets by vehicles exceeding the 20,000 pounds gross vehicle weights by 10 vehicles or more per day; or
d.
As otherwise deemed necessary by the public works director.
2.
If the division application does not include residential development, a TIA shall be required when a land use application involves one or more of the following actions:
a.
Any proposed development or land use action that a road authority, including the city, Jackson County or ODOT, states may have operational or safety concerns along its facility(ies);
b.
An increase in site traffic volume generation by 250 average daily trips (ADT) or more;
c.
An increase in peak hour volume of a particular movement to and from the state highway by 20 percent or more;
d.
An increase in use of adjacent streets by vehicles exceeding 20,000 pounds gross vehicle weight by 10 vehicles or more per day;
e.
The location of the access driveway does not meet minimum sight distance requirements, as determined by the city engineer, 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 in the discretion of the city planner;
f.
A change in internal traffic patterns that, in the discretion of the city planner, may cause safety problems, such as back-up onto a street or greater potential for traffic accidents; or
g.
As otherwise deemed necessary by the public works director.
B.
Traffic Impact Analysis Preparation. A traffic impact analysis shall be prepared by a traffic engineer or civil engineer licensed to practice in the state of Oregon with special training and experience in traffic engineering. The TIA shall be prepared in accordance with the public works department's document entitled "Traffic Impact Analysis." If the road authority is the Oregon Department of Transportation (ODOT), consult ODOT's regional development review planner and OAR 734-051-180.
