Transportation Demand Management Plans for Commercial / 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. 

1. Is your project subject to the TDM requirement? (all four must apply to trigger requirement)

  • Located in a Commercial/ Mixed Use Zone (CR, CX, CM1, CM2, CM3, CE)
  • Included more than 10 new dwelling units
  • Located close to transit (within 500 feet of a Transit Street and 1,500 feet of a Transit Station)
  • Located outside of the Central City Plan District 

2. Select a TDM Plan Option
