When to update a Transportation System Plan?

Like all planning documents, a TSP should be updated periodically to reflect growth and change. Many circumstances can trigger a TSP update, including state or regional compliance issues, changing community priorities, and funding availability.

Does my community need to have a TSP?

As allowed by the Transportation Planning Rule, the following may not be required to develop or adopt a TSP:

Cities with fewer than 10,000 people
Cities with fewer than 10,000 residents
Counties with fewer than 25,000 people
Counties with fewer than 25,000 residents
Unincorporated areas with fewer than 10,000 people
Unincorporated areas of counties within urban growth boundaries with fewer than 10,000 residents

The Department of Land Conservation and Development may grant a whole or partial exemption from Transportation Planning Rule requirements for these jurisdictions. Exempt jurisdictions are still eligible for state grant funding to prepare or update a TSP and may not be obligated to fulfill all the requirements in the Transportation Planning Rule.

How long will it take?

Completing all elements of a TSP typically takes 12-15 months, with additional time for public adoption. Scope, complexity, staff availability, and number of agency participants can influence the timeline.

What might trigger an update?

Change in population  

Unanticipated changes to the location or rate of change in population or employment.

  Specific Examples
  • Urban Growth Boundary amendments
  • Annexations
  • New or relocated employment center
Bike in car lane vs. bike in bike lane. Reflects changing community priorities.  

Changed community priorities that necessitate a reexamination of planned facilities and services.

  Specific Examples
  • New economic development policies and programs that depend on adequate infrastructure to succeed
  • Emergency preparedness objectives requiring planning for evacuation and supply routes
  • Community health objectives and community interest in enhancing and investing in active transportation modes
  • Funding constraints and the need to maximize the efficiency of the existing transportation system (i.e., community focus on active transportation and cost-effective improvements)
  • Newly adopted Americans with Disabilities Act Transition Plans.
Calendar showing TSP is out of date  

The current TSP document no longer addresses the existing or future transportation needs/vision/standards of the local jurisdiction.

  Specific Examples
  • Need for new transportation projects based on updated future travel demand and a reassessment of capacity, deficiencies, and needs
  • Need to update a Capital Improvement Program
  • Plan amendments or zone changes have had unanticipated impacts on the community or one or more transportation facilities
  • Specific modal elements need inclusion or update
  • Roadway functional classifications and/or design standards between local and state jurisdictions are inconsistent
  • Concerns about underlying conditions and capacity of roadways (reevaluation and reassessment needed)
  • Current TSP planning horizon is less than 15 years from the present date
Crossed out smog cloud  

The current TSP is inconsistent with other local community plans or policies.

  Specific Examples
  • Updated comprehensive plan elements
  • New or updated transit development plan
  • Updated system development charges/transportation impact fees
  • Scheduled periodic review work program
  • Urban Reserves designation
  • Planning for the location or relocation of a major transportation facility
  • Transportation refinement plans (draft, adopted by resolution, or legislatively adopted by reference into the TSP)
  • Planning for major improvements on the state system (e.g., freeway interchanges or new bypasses)
  • Plans related to access to and connectivity with other transportation modes (e.g., air, rail, transit, freight)
Autonomous vehicle  

The current TSP is inconsistent with state or regional plans or policies.

  Specific Examples
  • For jurisdictions within a Metropolitan Planning Organization area, amendments to the area’s Regional Transportation Plan
  • Changes to state policy or requirements in the Oregon Transportation Plan or the associated mode and topic plans
  • Proposed major projects that require Statewide Planning Goal exceptions (e.g., Goal 3, Agricultural Lands)

When is a TSP update required?

An update is required under the Transportation Planning Rule in the following cases:

The jurisdiction is required and scheduled to undertake a Periodic Review process based on an evaluation and work program developed with the assistance of the Oregon Department of Land Conservation and Development; elements of the TSP have been identified as areas for review and possible updates.

While the process of completing a task on the work program varies based on the needs and practices of the jurisdictions and the nature of the task, the local process for developing a TSP is essentially the same as it would be for a plan amendment outside periodic review. The notice requirements, however, are different.

Periodic review requirements are established in ORS 197.628 to 197.650, and are interpreted and supplemented by OAR 660, Division 25.

The jurisdiction is undertaking a major plan amendment that would significantly affect one or more transportation facilities.

The TPR requires local jurisdictions to evaluate proposed plan amendments and zone changes for consistency with adopted land use and transportation plans. This part of the TPR, OAR 660-012-0060, is commonly referred to as Section -0060. It is designed to address several important objectives:

  • Ensuring that local governments consider transportation impacts of changes to land use plans
  • Keeping land use and transportation plans in balance with one another by ensuring that the planned transportation system is adequate to support planned land use
  • Addressing how needed transportation improvements will be funded
  • Accommodating new development in a way that minimizes its traffic impacts

Section -0060 specifies a category of facilities, improvements, and services that can be assumed to be in place or committed and available to provide transportation capacity over a 20-year planning horizon. The Transportation Planning Rule guides local jurisdictions in determining what transportation improvements are reasonably likely to be provided by the end of the planning period when considering amendments to local plans and land use regulations.

For cities in a Metropolitan Planning Organization area, and there is a new or updated Regional Transportation Plan.

Local TSPs must be consistent with the applicable Regional Transportation Plan. A jurisdiction within a Metropolitan Planning Organization area must make findings that the proposed Regional Transportation Plan amendment or update is consistent with the local TSP and comprehensive plan or adopt amendments that make the Regional Transportation Plan and the TSP consistent with one another. (OAR 660-012-0016) TSP updates must occur within one year of the adoption of a new or updated Regional Transportation Plan. (OAR 660-012-0055).

Statewide Planning Goal 12, Transportation, defines the State’s policies on transportation. OAR 660 Division 12, also known as the Transportation Planning Rule, implements Goal 12. The Transportation Planning Rule requires:

  • Most jurisdictions to prepare and adopt a regional or local transportation plan that serves as the transportation element of a comprehensive plan. (OAR 660-012-0015)
  • Local TSPs to be consistent with Regional TSPs. Where elements of the Regional TSP have not been adopted, coordination between the city/county and the regional transportation planning agency in the preparation of the local TSP is needed. (OAR 660-012-0015)
