The Portland Bureau of Transportation is updating its Transportation System Development Charge (TSDC) program. The current TSDC update process began in mid 2016 and is expected to end in July 2017. The update includes three main components:
Projects on the TSDC list are oriented toward accommodating development growth and improving travel for all modes: walking, biking, driving and transit. The current list was last updated in 2007. Some of the projects on that list are now complete, some have received funding from other sources, and some of them may no longer fit the city’s transportation priorities. Every few years, the City engages in an extensive public input process to reaffirm and amend the list of projects to guide spending of TSDC revenues. As part of this process, the project team is also revisiting the criteria that determine whether projects are eligible for TSDC funding.

To streamline the TSDC program and ensure that it is aligned with the goals of the City’s Transportation System Plan, the project team is recommending that the TSDC program be restructured to simplify how TSDCs are calculated. This will be done in two primary ways. First, the TSDC rates would be based on system value per trip, which will be calculated both for the existing transportation system and for a 10-year list of eligible TSDC projects. Second, the TSDC’s would be based on the total number of person trips generated by development within the city. This would mean calculating the value of a “person-trip” within our current transportation system and using this cost as the maximum rate that could be charged per future trip to pay for projects on the TSDC list. (The actual cost per future trip may be lower than this rate.)
Each development type pays a TSDC rate that is based on how many trips the new development is expected to create. This helps to fund the infrastructure improvements that are needed to accommodate new growth. The project team is recommending that these rates be updated so they are based on the most current data about person trip generation.
Since not all person trips have the same impact on the transportation system, the project team is working to identify ways to make adjustments to fees based on development location and land use context. The project team will also be updating guidance for how developers can document trip generation rates based on unique land uses.
