Damascus Mobility Plan

Main Content

After nearly a year of study and public input, beginning in summer 2021, the Damascus Mobility Plan project has identified roadway improvements needed to the County transportation system to enhance safety, equity, and mobility for the traveling public in the Damascus area over the next 20 years. The project has focused primarily on passenger and freight vehicle travel. It was developed based on existing land use and zoning designations in the study area.

The draft report was presented to the Board of County Commissioners on July 27, 2022, and is moving forward to public hearings:

  • Aug. 22, 2022; 6:30 p.m. – Planning Commission
  • Sept. 28, 2022; 10 a.m. – Board of County Commissioners

Next Steps

After the Board of County Commissioners public hearing, the Board will consider approving the following amendments to the Comprehensive Plan Chapter 5 – Transportation System Plan:

  • Amend Tables 5-3a through 5-3d to include transportation projects identified in the Damascus Mobility Plan
  • Amend Map 5-11a to include transportation projects identified in the Damascus Mobility Plan
  • Add the Damascus Mobility Plan to Comprehensive Plan “Appendix B Summary of Supporting Documents”
  • Make minor amendments to Comprehensive Plan Chapter 5 to remove references to the City of Damascus, as well as more clearly define “Urban” and “Rural” in the definitions section.

The study area includes most of the former City of Damascus planning area inside the Portland Metropolitan Urban Growth Boundary (UGB), except for:

  • Properties and roadways generally west of 190th Drive that are planned by the City of Happy Valley through the Pleasant Valley/North Carver (PV/NC) Comprehensive Plan.
  • Projects along OR 212, a state highway, that are the responsibility of the Oregon Department of Transportation (ODOT).

Project Timeline

The project is expected to take about one year to complete. Throughout that time the project team will report to and seek input from area residents, businesses and property owners through public meetings, presentations at community meetings, social media, mailings, email updates and the project website. In addition, two major open houses are planned to share information, answer questions and listen to comments and suggestions.

Major project milestones are shown below.

project timeline



Clackamas County updates its Transportation System Plan (TSP) for unincorporated areas of the county approximately every 10 years.  When the last update took place, in 2013, Damascus was a city, so the area was not included in the county plan. Since then the city was disincorporated in 2016 and lawsuits related to that action ended in 2020.

As a result, the study area’s land use and transportation system are governed by the County’s Comprehensive Plan and 2013 Transportation System Plan, which are based on a more rural context than the urban context that had been contemplated by the former city.

This Damascus Mobility Plan will now provide transportation planning for the area formerly in the city boundaries, and the findings from this Plan will be incorporated as part of the next County Transportation System Plan Update, expected in 2022-24

While this project focuses on road improvements, the recently adopted Clackamas County Transit Development Plan identified transit improvements for the Damascus area, and the Clackamas County Bike Walk Plan (currently underway) will provide recommendations for active transportation improvements in Damascus.


The City of Damascus did develop some transportation system plans, but those were never finished and became invalid when the city disincorporated and the area once again became a Clackamas County responsibility. With disincorporation, applicable land use and transportation plans for the Damascus area reverted to the County’s Comprehensive Plan and Zoning & Development Ordinance (ZDO).

Yes, it will. Happy Valley, through the Pleasant Valley/North Carver (PV/NC) Comprehensive Plan,  has been working on plans for transportation improvements in the western portion of Damascus from 190th Avenue west to the existing city limits of Happy Valley. The County’s Damascus Mobility Plan will assume the future development of the proposed Happy Valley transportation improvements in that area per the provisions of the Urban Growth Management Agreement (UGMA) approved by the county and the City of Happy Valley.


No, this project is focused on roadway transportation facilities to support passenger and freight vehicle travel. After the disincorporation of the City of Damascus, Clackamas County re-adopted the land use plans and zoning requirements that were in place prior to the formation of the City of Damascus. This project will assess existing and future traffic based on the re-adopted land use plans and zoning requirements. Land use changes are addressed through large-scale urban planning efforts and updates to the Comprehensive Plan.


The budget of $200,000 comes from funds transferred to the County following the disincorporation of Damascus, and from County planning funds.


Other Projects and Plans in the Area

Listed below are other transportation plans and projects that have taken place, are underway or are planned in areas adjacent to Damascus Mobility Plan project area.

Project/Lead Relationship to Damascus Mobility Plan
Clackamas County Transportation System Plan (TSP), 2013 Currently does not include county roadways within Damascus, but provides a framework for identifying and evaluating projects.
Clackamas County Active Transportation Plan (ATP), 2015 Identifies key active transportation routes to connect destinations and communities in Clackamas County, and includes a recommendation to provide access between Happy Valley, the Clackamas Regional Center, and the Damascus Area.
Clackamas County Drive to Zero Transportation Safety Plan, 2019 Clackamas County has a goal to eliminate fatal and serious injury crashes on its roads by 2035. This Plan describes the broad areas on which the county, its partner organizations, and its residents must focus to achieve this goal. These emphasis areas represent an evidence-based approach to reducing fatal and serious injury crashes. 
Clackamas County Transit Development Plan (TDP), 2021 Includes near-term recommendations for service on Highway 224 and medium- and long-term recommendations for service within Damascus on Sunnyside Road and Highway 212.

SE 172nd Avenue/190th Drive Corridor Management Plan(Clackamas County, Happy Valley, Gresham)

Provides a vision for the SE 172nd Avenue/190th Drive Corridor just west of the project study area.
Sunrise Project Final Environmental Impact Statement (ODOT, Clackamas County, Metro, Happy Valley) Identifies a preferred alternative for the Sunrise Corridor between I-205 and the Rock Creek Junction. This effort informed an assessment of options for the Sunrise Corridor that was conducted as a discrete part of the Damascus Mobility Plan.
