1120 SW Fifth Ave, Suite 800, Portland, OR 97204
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.
