Traffic Engineering and Transportation
The Lake Oswego Transportation System includes more than 178 miles of streets, 32 traffic signals, 12.0 miles of pedestrian pathways, and shared ownership of the Jefferson Street Rail Line (aka Willamette Shoreline Trolley) within the city limits. The streets are classified as major and minor arterials, major collectors, neighborhood collectors, and local streets; traffic counts are available on line.
The City’s Transportation System Plan (TSP) provides a plan for the development of the City’s transportation infrastructure. Specific projects are further developed as resources become available. The TSP includes elements for roadways, bike, pedestrian, transit and rail related improvements.
Concerns, comments and questions regarding traffic related matters can be sent to firstname.lastname@example.org, and a staff person will respond. Make sure to include your contact information if you would like a response. For more information, please contact the Engineering Division at 503-635-0270. You may contact others in the division by locating them in our staff directory.
The City of Lake Oswego’s transportation system plan (TSP) is an important document for long-range planning purposes as well as a tool for current developments. The TSP provides a snapshot of the existing system, immediate changes, and future plans into year 2035. The previous TSP was published in 1997.
Events can often impact traffic, whether it be for a large wedding with major street parking, film production or a fun run. Review and permits for such events by the traffic staff in engineering is often required prior to the event. Permits are requested for submission 45 days before the event.
You may have seen some new types of traffic signals installed throughout the metropolitan area. The Flashing Yellow Arrow (FYA) signals are the new standard for permissive left turn movements. A permissive turn is one that can be made through gaps in oncoming traffic.
Neighborhood Speed Watch is a public awareness program that solicits concerned Lake Oswego citizens as volunteers to participate in actively addressing and impacting the problem of numerous vehicles exceeding legal speeds on neighborhood streets.
The purpose of Neighborhood Traffic management Program is to give citizens greater participation in decisions regarding traffic management on neighborhood streets in order to promote the safety and livability of residential neighborhoods through the use of education, traffic management devices and enforcement.
System development charges are fees paid by new development to recover a portion of the cost of existing infrastructure and to help fund new infrastructure necessary to serve new development. Infrastructure includes streets, the water system, sanitary and storm sewers, and parks.
All construction activities within the public right-of-way require an approved traffic control permit from the City of Lake Oswego.
The purpose of a Traffic Control Plan (TCP) is to allow the contractor to work within the public right-of-way efficiently and effectively while maintaining a safe, uniform flow of traffic.
There is no fee for a traffic control permit.
Average Daily Traffic count information for most of Lake Oswego's major streets and some of our local streets is available online. The interactive map is available for recent years starting in 2011.
