Transportation System Plan

Clackamas County's Transportation System Plan (TSP) was adopted by the Board of Commissioners in December 2013. An Active Transportation Plan was added to the TSP in 2015.

The TSP reflects all relevant national, state and regional transportation and planning requirements, and provides policies, guidelines and projects to meet transportation needs for residents, businesses and visitors in unincorporated Clackamas County for 20 years.

A Public Advisory Committee and a Technical Advisory Committee guided the two-year plan development process, based on extensive input from the public, the business community, planning and transportation experts, and public and private partners. The TSP includes more than 300 needed transportation projects identified by the community and transportation professionals throughout unincorporated Clackamas County over the next 20 years, though funds are likely to be available for only a small percentage of the total.

The TSP also includes updated policies to guide development of the projects that:

  • Look at the transportation system through a local perspective (rural and urban);
  • Specifically address safety, health, equity and sustainability;
  • Integrate transportation with land use;
  • Address active transportation (bicycling and walking) and accessibility needs;
  • Support the movement of freight; and
  • Ensure compliance with national and local regulations, including a change of intersection and roadway performance standards.

"This transportation plan has evolved over more than two years with extensive public involvement," said County Commission Chair John Ludlow in December 2013. "It will help us continue to provide the safe and reliable transportation system our residents and businesses need and deserve."

Brief Overview

TSP Vision

Building on the foundation of our existing assets, we envision a well-maintained and designed transportation system that provides safety, flexibility, mobility, accessibility and connectivity for people, goods and services; is tailored to our diverse geographies; and supports future needs and land use plans.

TSP Goals

  • Sustainable: Provide a transportation system that optimizes benefits to the environment, the economy and the community.
  • Local Business and Jobs: Plan the transportation system to create a prosperous and adaptable economy and further the economic well-being of businesses and residents of the county.
  • Livable and Local: Tailor transportation solutions to suit the diversity of local communities.
  • Safety and Health: Promote a transportation system that maintains or improves our safety, health, and security.
  • Equity: Provide an equitable transportation system.
  • Fiscally Responsible: Promote a fiscally responsible approach to protect and improve the existing transportation system and implement a cost-effective system to meet future needs.

TSP Projects

  • Tier 1: 20-year capital projects – Needed projects and investments matched with anticipated funding
  • Tier 2: Preferred capital projects – Projects and investments needed to meet population, housing and employment projections, but that don't have identified funding at this time
  • Tier 3: Long-term capital project needs – Projects that would be beneficial to do if funds were available
