Transportation Demand Management Rulemaking for Mixed Use Zones

New requirements for Mixed Use Zone Developments: 

Under Title 33, a development in a commercial/ mixed use zone that includes more than 10 new dwelling units is required to have a Transportation Demand Management (TDM) Plan at the time of development permit issuance. 

These TDM Plans are meant to prevent, reduce, and mitigate the impacts of the new development on the transportation system, neighborhood livability, safety, and the environment, while providing safe and efficient mobility options. 

General Mixed Use Project Background

The primary policy goal of the Mixed Use Zoning Update Project is to develop new mixed use zoning designations to implement Portland's new 2035 Comprehensive Plan, which calls for managing growth and creating healthy, vibrant neighborhoods. Roughly 80% of new housing built over the next 20 years is expected to be multifamily development, much of it in centers and corridors within the mixed use zones. These mixed use area will continue to evolve as places that meet the daily needs of nearby residents and are well served by shops, services, transit and other public services. 

What is Happening Now

Through engagement with other City Bureaus and the development community, PBOT is developing guidance documents regarding the implementation of TDM requirements in Mixed-Use Zones. 

The Administrative Rule and Procedures Guideline will assist City staff and stakeholders in implementing two policy documents passed by City Council in 2016: Section 14 of the Transportation System Plan (Parking and Demand Management) and the Mixed Use Zones Project
