Pre-Approved TDM Plan Information


An applicant has two options to fulfill the Transportation Demand Management (TDM) requirement under 33.266.410; a Custom TDM Plan (land use review) or a Pre-Approved TDM Plan (an administrative process).

The general components of the the Pre-Approved TDM Plan include the following:

  • Multimodal financial incentives: A one-time Multimodal Incentive Fee, equivalent in value to an annual TriMet pass per dwelling unit (see Transportation Fee Schedule for current rates). The money is held in a City account during construction, and then used for multimodal incentives for building tenants at occupancy. Multimodal incentives could include: Bike-share membership or ride credits, TriMet passes (or value on a TriMet Hop pass), Streetcar passes, Car share incentives, or Carpool incentives.  
  • Transportation options information: provided by PBOT and distributed to tenants for the first four years of building occupancy. 
  • Annual transportation survey: administered by PBOT, with property management assistance, of building tenants for first four years of building occupancy.
