Transportation Demand Management Rulemaking for Mixed Use Zones

New requirements for Developers in Commercial Mixed Use Zones: 

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

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. 

What is Happening Now

Through engagement with other City Bureaus and the development community, PBOT is developing guidance documents regarding the implementation of the TDM requirements in Commercial 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
