Thompson Road 2022 open house summary

Thompson Road logoThe Thompson Road Online Open House was active January 7-23, 2022, and was viewed by 331 people and received 66 responses. A summary of questions (in bold text) and responses is below.


Why do we need to replace the existing 6-foot sidewalk with a 10-foot multiuse path and cause the removal of thriving mature trees?

Multiuse paths create a safer, more comfortable transportation opportunity for people of all ages and abilities to walk, bike and roll between their neighborhoods, the elementary school and the future park. Washington County’s Board of Commissioners gave staff direction to build a 10-foot multiuse path with a 4-foot planter area between the path and the street along Kenny Terrace (the future Thompson Road alignment).

Many of the existing trees have outgrown the available space and are causing damage to the sidewalks. The project includes planting new tree species that are more appropriately sized for the space and surrounding facilities.


Can a marked crosswalk and pedestrian crossing warning signs be installed on NW Kenny Terrace at NW Dalton Ranch Lane crossing? 

A marked pedestrian crossing of Kenny Terrace (future Thompson Road) with a rapid flashing beacon will be added at Dalton Ranch as part of the project. View a similar crossing 


Will the median at (Old) Thompson Road and 135th Avenue be removed to allow left turns?

A median is required by ourdesign standards.  The 40 mph speed limit requires more sight distance than exists to allow safe left turns. The speed limit needs to be reduced to 25 mph before left turns can be considered. 

The median will not be removed as a part of this project.  The median is required for safety due to limited sight distance around the curve.


How will fire engines leave the area during road closures?

We will work with with Tualatin Valley Fire & Rescue (TVF&R) and other service providers throught all stages of the project. The closures will be scheduled so there will be  open access to/from the TVF&R station. The project includes two separate road closures, each will last about 30 days.


How will the new Thompson Road alignment impact student drop-off and pickup at Findley Elementary?

Findley Elementary student drop-off and pickup has been considered in the design of the project.

We will coordinate with school staff throughout construction to maintain access with minimal delays.


What traffic control will be used at Kenny Terrace/Thompson Road and Old Thompson Road?

A stop sign will be installed on existing Thompson Road (Old Thompson Road) where it intersects Kenny Terrace (new Thompson Road). There will be a clear line of sight in both directions.


How does this project impact the access to Arbor Cascadian neighborhood?

The existing Thompson Road will dead end at the Findley Elementary driveway. Access to the Cascadian neighborhood at 135th will remain right-in and right-out.  Evergreen Street access will remain open throughout construction.
