Transportation System Development Charge Update

The Bureau of Transportation is updating its Transportation System Development Charge (TSDC) for the third time. These updates produce a project list to accommodate growth, refine the methodology for calculation of the charge, and may impact the rates charged to new development for the infrastructure needed to accommodate growth.


Project List

The project list will be developed based upon the previous list (for projects that will continue into the new list) and from the update of the Transportation System Plan (TSP). The project list selection will utilize the TSP selection criteria and include consideration of leverage or match funds being sought to help highlight project with a high likelihood of receiving funds in addition to the TSDC funding.


The goal of the update will refine the technical methodology to move to “person trips” rather than the typical “auto-centric” calculation methodology. This update may also consolidate the range of categories to simplify the methodology calculations. Portland would also seek to not penalize infill multi-family developments that support the City’s land-use goals. The TSDC update will feed into changes to Level Of Service policy changes in the future moving from a system-wide level to an individual site level.
