How to Update a TSP
A TSP can be prepared in different ways, but there are four phases that are always followed:
This TSP Guidelines site provides information on how to complete these four phases to successfully create or update a TSP for your community. The TSP Guidelines are based primarily on requirements and recommendations from the TPR
(OAR 660-012), but they also incorporate the current best practices in the long-range planning of a transportation system.
Requirements from the TPR will be designated with the word
shall in the TSP Guidelines. Recommendations from the TPR or current best practices are designated with either a
should or a
could in the TSP Guidelines. Although these TSP Guidelines are meant to support anyone preparing a TSP, those working on a TSP should have a basic understanding of the TPR as well.
While the TSP Guidelines document the requirements and recommendations for preparing a TSP, they do not cover specific analysis procedures used to meet those requirements. For Oregon-specific guidance for completing analysis during the Prepare Phase of the TSP, you will need to review the ODOT
Analysis Procedures Manual (APM). The analysis procedures used to meet each requirement may differ for each TSP based on size of the community, whether travel demand models are available, and other factors.
Why do TSP guidelines differ between metropolitan and non-metropolitan areas?
The TPR was updated by the Oregon LCDC in 2022 and 2023 to implement the Climate-Friendly and Equitable Communities (CFEC) program. These updates apply only to cities and counties in metropolitan areas. As a result, as discussed in OAR 660-012-0011, there are sections of the TPR that apply statewide, within metropolitan areas, or within non-metropolitan areas. All cities are either subject to the rules for metropolitan areas or non-metropolitan areas, but not both. Different parts of a county may have different applicable rules based on metropolitan area boundaries.
The TSP Guidelines differ in how to prepare a TSP for a transportation system within a metropolitan area versus non-metropolitan area. Key differences are summarized in the following phases:
-
Within metropolitan areas, jurisdictions with more than 5,000 residents should designate Climate Friendly Areas (CFAs) prior to scoping the TSP (the Metro 2040 Regional Centers serve as CFAs within the Portland metropolitan area). If CFAs are not designated before scoping the TSP, they must be adopted prior to TSP adoption. Additional land use and bicycle parking requirements may also need to be met as outlined in the TPR.
Special considerations should be given to metropolitan areas when scoping the TSP, as their requirements differ from non-metropolitan areas for the Prepare, Adopt, and Implement phases, as described below.
- Within metropolitan areas, a major equity analysis is required for TSP updates. Guidance on this work is provided on DLCD’s website.
- Requirements for documenting the existing conditions and determining existing needs differ between metropolitan areas and non-metropolitan areas, including major differences in the required inventory documentation.
- Within metropolitan areas, the funding review has more specific requirements.
- There are different requirements when developing solutions for metropolitan areas versus non-metropolitan areas. For example, in metropolitan areas, some roadway projects may be subject to an enhanced review process that requires consideration of alternatives.
-
Within metropolitan areas, there are several factors that must be used when evaluating alternatives and prioritizing
projects.
-
Within metropolitan areas, the development of a financially constrained list must follow specific steps and make significant progress toward reducing climate pollution.
- Within metropolitan areas, performance standards must be adopted that meet the TPR requirements.
- Within metropolitan areas, performance tracking must be completed based on performance measures and targets that meet TPR requirements.
