Transportation System Plan (TSP)

About the TSP

Portland is projected to add 140,000 new jobs and 260,000 new residents over the next 20 years. As Portland and the region grow, however, there is a continuing challenge to maintain the natural environment, economic prosperity, and overall quality of life. If in 2035 the percentage of people who drive alone to work remains the same as it is now (nearly 60 percent), traffic, carbon emissions, and household spending on vehicles and fuel will all worsen significantly. In order to accommodate this growth, our transportation system must provide Portlanders safer and more convenient ways to walk, bike, and take transit for more trips. The 2035 Transportation System Plan guides investments to maintain and improve the livability of Portland by:

  • supporting the City’s commitment to Vision Zero by saving lives and reducing injuries to all people using our transportation system

  • limiting traffic congestion so transit and freight vehicles can move more reliably

  • reducing, carbon emissions and promoting healthy lifestyles

  • keeping more money in the local economy, as we spend less on vehicles and fuel

  • creating great places

The Transportation System Plan is the 20-year plan to guide transportation policies and investments in Portland. The TSP meets state and regional planning requirements and addresses local transportation needs. Transportation planning that promotes active transportation modes is essential to preserving the City’s livability and for the protection of the natural environment. Constructing significant amounts of new automobile capacity to accommodate growth is not a viable option because of the enormous costs and impacts. Adding more streets and parking lots divides neighborhoods, uses valuable land, encourages urban sprawl, and has negative environmental impacts. Alternative approaches, supporting a safer, more affordable and more complete multimodal transportation network must be used to ensure integrated, comprehensive solutions. 

The Transportation System Plan helps implement the City’s 2035 Comprehensive Plan in addition to the region’s 2040 Growth Concept by supporting a transportation system that makes it more convenient for people to walk, bicycle, use transit, and drive less to meet their daily needs. The TSP also recognizes that the transportation system must help grow and sustain the City’s economic health by accommodating the needs of businesses and supporting Portland’s role in the international economy.

The 2035 TSP includes:

  • Goals and policies that guide the maintenance, development and implementation of Portland’s transportation system

  • Objectives that further the implementation of the goals and policies

  • A list of projects and City wide programs along with a financial plan that would accommodate 20 years of population and employment growth

  • Master street plans and modal plans

  • Strategies and regulations for implementation, including street classifications

Elements of the TSP

The TSP is both an implementation tool and a supporting document to the Comprehensive Plan. It contains the transportation element of the City’s Public Facilities Plan, and the List of Significant Projects and Citywide Programs. The TSP also provides more detail than the Comprehensive Plan by including additional supporting information about transportation system conditions.

Transportation System Plan Updates

In order to keep the TSP current and up-to-date with recent transportation planning and development activities, it is updated at regular intervals. The first two updates in the mid-2000s were not intended to include new policy initiatives. They were primarily technical in nature and included corrections, updates to project descriptions, updates on studies, and inclusion of new master street plans adopted as a part of planning efforts.

The first TSP was adopted by Council in 2002 (Ordinance 177028).

The first update was completed and adopted by City Council on October 13, 2004 (effective date, November 12, 2004; Ordinance Nos. 178815 and 178826).

The second update was completed and adopted by City Council on April 5, 2007 (effective date, May 5, 2007; Ordinance No 180871). While primarily technical in nature, this update also included new policy language to implement the City’s Green Street Policy.

Stage 1 TSP Update was a part of the City’s Comprehensive Plan update process and a component of the state’s Periodic Work Plan Task 4. It included Goals, Policies, Projects and Programs and a Financial Plan. It was adopted by City Council in June 2016.

The Stage 2 TSP Update was a part of the City’s Comprehensive Plan update and changes were made to implement the Comp Plan, as well as reflect adopted plans and classification changes since the last update in 2007. Periodic Work Plan Task 5. It was adopted by City Council in December 2016.

TSP Stage 3 TSP Update incorporated regional information, updated geographic policies, updated objectives, changes to street classification for traffic, transit and emergency response, modal plans, and other changes as identified. It was adopted by City Council in May 2018.
