Council seeks public comment on Transportation System Plan

First revision since 1997 includes wish list of 55 projects


It’s been a two-year process, but the Lake Oswego City Council is preparing to finalize an updated version of its Transportation System Plan that includes a wish list of 55 projects ranging from lane realignments and traffic signal adjustments to new curbs and upgraded sidewalks.

The plan is a sweeping review of the city’s current traffic system and serves as a long-term “needs analysis” that largely addresses connectivity gaps, said Amanda Owings, a traffic engineer with the city’s Public Works Department. The state Department of Land Conservation and Development requires Lake Oswego to conduct a periodic review of its comprehensive plan, although the TSP has not been updated since it was first adopted in 1997.

The updated draft includes studies by Kittelson and Associates Inc. and is the result of a two-year process that has included input from neighborhood associations and the public. The plan has been under the advisement of the Transportation System Plan Advisory Committee, which includes representatives from Clackamas County, Oregon Department of Transportation, Metro and TriMet.

“It’s very important for a project to be on the TSP before it becomes eligible for grants,” Owings said. “It shows there’s been a need, a public understanding of the project, that the public has been made aware of it. This is the first level of initiation for a project before it can really be awarded funding.”

The list of 55 projects includes lane realignments, adjustments to traffic signal timing, roadway widening and additional signage. Several projects also identify a significant need for additional curbs and sidewalks, as well as ramps to make sidewalks compliant with the Americans with Disabilities Act.

The costliest project on the list is the first phase of Boones Ferry Road improvements, which includes widening and paving the roadway on the nearly half-mile stretch between Madrona Street and the intersection with Oakridge and Reese roads; upgrading sidewalks; improving traffic signals; and installing green features to slow and treat stormwater. Estimated cost: $29 million.

The majority of the projects are not prioritized. The plan is not a set itinerary of public projects, nor are projects included in the TSP guaranteed funding. Still, there are six projects that must be completed within a 20-year timeline, Owings said. Altogether, those projects will cost an estimated $1.3 million. They include:

  • Six Corners Enhancement, to improve access at the north leg of Iron Mountain and Bayberry Roads. Estimated cost: $580,000;
  • Restripe a northbound lane on Highway 43 toward McVey Avenue, and modify traffic-signal timing accordingly. Estimated cost: $250,000;
  • Intersection improvement at Jean and Pilkington roads, including turn-lane realignment. Estimated cost: $298,000;
  • Signal improvements at South Shore Boulevard and McVey Avenue. Estimated cost: $30,000;
  • Signal improvements at three points on Bryant Road. Estimated cost: $50,000; and
  • Highway 43 refinement plan to accommodate long-term traffic demands along the roadway as it passes through the city of Lake Oswego. Estimated cost: $100,000.
  • “If we get back to those six projects we know we have to do, everything else is dependent on funding becoming available, as we can find it,” Owings said.

    A public hearing on the Transportation System Plan will be held during the City Council meeting on Tuesday; it’s scheduled to begin at 6:30 p.m., in the City Council Chambers, 380 A Ave.
