Tualatin City Council Approves Transportation System Plan Amendments for 2045

In the heart of Tualatin's city hall, council members gathered on August 11, 2025, to discuss pressing transportation issues that could shape the future of the community. The meeting focused on the Transportation System Plan (TSP) amendments, which aim to address traffic flow and safety in the rapidly growing area.

One of the key discussions centered around the intersection of Twelfth Avenue and Fifteenth Avenue. Originally slated for a traffic signal, the project has now shifted to a broader intersection improvement plan, which may include options like a roundabout. This change reflects a strategic move to preserve flexibility for future developments that could increase traffic, particularly if new construction occurs north of Tualatin Road.

City officials emphasized that while this project has been moved off the financially constrained list, it remains on the unconstrained list, meaning it could still be pursued if safety concerns arise. The council is now tasked with prioritizing which projects to advance in the coming years, based on the comprehensive list included in the TSP.

Public feedback played a significant role in the meeting, with residents expressing their appreciation for the inclusive approach taken by city staff. One resident, Nancy, commended the efforts to balance active transportation needs with the frustrations of congestion, particularly on Tualatin Sherwood Road. She raised concerns about a potential grade separation project at the intersection of Twelton Sherwood Road and Boones Ferry Road, urging the council to prioritize local traffic and vulnerable populations over commuter convenience.

Another resident echoed these sentiments, highlighting the importance of investing in technology to improve traffic signal efficiency. They suggested that advancements in AI could help optimize traffic flow, especially at problematic intersections.

As the meeting progressed, council members engaged in discussions about the role of Metro in the prioritization process, clarifying that while Tualatin has the autonomy to set its own priorities, Metro's involvement is crucial for securing federal funding and ensuring compliance with regional transportation plans.

The evening concluded with a sense of optimism as council members and residents alike recognized the importance of thoughtful planning in addressing Tualatin's transportation challenges. With a commitment to community engagement and a focus on safety, the city is poised to navigate the complexities of growth while enhancing the quality of life for its residents.
