Clackamas to Columbia Corridor Plan

  • This project will deliver a plan for improving north-south travel in the Portland Metro area east of I-205.

    The Clackamas to Columbia Corridor (C2C) project has entered Phase 2 and is conducting public engagement (see schedule graphic in link below).

    • The final online public meeting will be held Thursday, Sept. 10, at 6:00 pm via Zoom; join the meeting here or add the meeting to your calendar.
    • Hear about collected community comments and provide input on the final plan.
    • Documents will be available to review on Sept. 1.

    A Steering Committee made up of elected representatives of Happy Valley, Gresham, Clackamas County, and Multnomah County met July 23 to review the project packages and a summary of the initial public input from the online open house. The Steering Committee will also meet September 16 to review any final community input and provide final direction on the plan.

    • Phase 1 inventoried a list of the previously planned and vetted projects from Transportation System Plans (TSPs) in the area and the 172nd/190th Corridor Management Plan.
    • Phase 1A represented a pause in the project and focused on properly aligning with the C2C priorities with the Get Moving 2020 regional investment measure.
    • Phase 2 is assessing the remaining projects within the corridor, developing potential investment packages (of projects), and seeking input from the project Steering Committee and the general public via virtual events due to COVID-19. Through this feedback process, the composition and priority of the investment packages will be formulated for inclusion in the draft C2C Corridor Plan. This plan will then provide a roadmap for the agencies to seek funding and ultimately implement the corridor overtime.
    • Final/adoption phase (October 2020 through March 2021). In this last phase, the counties and cities involved will hold public hearings and seek to adopt the C2C Corridor plan by reference to their respective TSPs.

    Project Background

    Which roads does the plan include?

    The Clackamas to Columbia Corridor (C2C) project will look at a corridor:

    • Comprised of Southeast 181st, 182nd, 190th and 172nd avenues
    • Connecting I-84 in Multnomah County and Highway 212 in Clackamas County

    This corridor serves:

    • Residential areas in Gresham, Portland, Happy Valley and unincorporated Clackamas County
    • Commercial districts and industrial job centers in Clackamas County
    • The Columbia Corridor in Gresham, Portland and Multnomah County

    What need does this project serve?

    The Clackamas to Columbia Corridor is the only major north-south travel route east of I-205. Used heavily as a major travel route, it is not continuous.

    Improving this route will benefit all modes of travel through some of the fastest growing and most under-served communities in the Metro area. The Clackamas to Columbia Corridor is recognized within Metro Mobility Corridor 24 and the 2018 Regional Transportation Plan.

    The Portland metro area east of I-205 continues to grow and change. Some examples:

    • The City of Happy Valley is anticipated to expand.
    • Damascus is no longer an incorporated city.

    As Gresham, Happy Valley and Clackamas County plan for growth, the area needs an integrated transportation plan. The Clackamas to Columbia Corridor project will deliver a plan for improving north-south travel.

    Several partner agencies’ planning projects, in progress or recently completed, will influence this project: 

    What will the Clackamas to Columbia Corridor plan do?

    • Identify transportation improvements to improve mobility and access.
    • Prioritize which improvements to fund and build soonest.
    • Develop a consistent set of policies and street designs for each partner agency.
    • Within Metro's 2018 Regional Transportation Plan, document needs and reasons for investment in projects the plan identifies.

    Project funding

    This project is partially funded by a grant from the Transportation and Growth Management (TGM) program, a joint program of the Oregon Department of Transportation and the Oregon Department of Land Conservation and Development.

    The TGM grant is financed, in part, by federal Fixing America’s Surface Transportation Act (FAST Act), local government and State of Oregon funds.

    What will partner agencies do as a result of the project?

    The cities of Gresham and Happy Valley, along with Multnomah and Clackamas counties, will pursue adoption of the applicable parts of the plan when updating their transportation system plans.
