Transportation System Development Charge Update

PBOT has completed an update of its Transportation System Development Charge (TSDC) methodology and capital project list. A TSDC is a one-time fee assessed new development to help fund the cost of capital improvements to serve a growing population. The City of Portland (CITY) first adopted TSDCs in 1997 and last updated the methodology and project list in 2017.

PBOT has been working since April 2016 to update its TSDC program which consist of three primary elements: 1) TSDC methodology, 2) Capital project list and 3) rate schedule. The update process has included robust community outreach effort to provide input on each program element. We invite you to review the updated methodology and capital project list contained in the 2017 Transportation System Development Charge Rate Study which may be found here.

Proposed TSDC Rate Schedule and Funding Level

With Portland expected to grow in the next 10 years, improvements to the transportation system are necessary to provide travel options to accommodate growth while meeting Vision Zero, Climate Action, and City Comprehensive Plan goals; however, the overall cost of living in Portland continues to be a concern. Portlanders should have the best transportation system possible. Based on input from stakeholders, PBOT directors therefore support TSDC rates based on funding 50 percent of the eligible TSDC project costs.

Summary of TSDC Project Costs and Recommended Rate 

Total Estimated Project Costs 

$609.5 Million (City-only Projects)

Total Estimated TSDC Eligible Project Costs 

$494.3 Million (City-only Projects) plus

$   95.0 Million (Matching funds for Regional Projects)

$589.3 Million (Total TSDC Eligible Costs)


Recommended TSDC Assessment – See attached fee schedule 

$294.7 Million (50% of Total Estimated TSDC Eligible Cost)


A public hearing on the TSDC update has been scheduled for July 26th, at 2 p.m. in Council Chambers, 1221 SW 4th Avenue, Portland, Oregon. The proposal to City Council on July 26th, will include adoption of the attached rate study and project list, establishment of TSDC rates, and updates to City Code 17.15, Transportation System Development Charges.
