The full text of the guide is available as a PDF document (1.62 MB). What follows in an excerpt from the Introduction.  


The purpose of this guide is to provide procedures for implementing transportation system development charges (Transportation SDCs or TSDCs) in the City of Portland. The guide follows how TSDCs are applied to individual developments, how they are calculated, paid, and deposited, and how TSDC revenues are ultimately used (expended). The guide also addresses refunds, appeals, recordkeeping, and updates of the TSDC Capital Improvement Program (which contains the list of projects authorized to be built using TSDC funds).

ORS 223.297 through 223.314 grant the City authority to impose a SDC to equitably spread the costs of essential capacity increasing capital improvements to new development. (17.15.010 B.)

This guide is based on and implements Chapter 17.15 of the Code of The City of Portland (first adopted by Ordinance 171301 in 1997). The guide presents information from the Ordinance in the sequence needed to determine a TSDC for an application for development. In addition, the guide provides forms, notifications, spreadsheets, and directions on a more detailed level than Chapter 17.15.

In instances where a requirement or direction is quoted verbatim from the Transportation SDC Ordinance (Chapter 17.15), the text appears in italics.
