Custom 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 Custom TDM Plan requires the applicant to go through a Transportation Impact Review (TIR) process as outlined in Title 33.852. Per the requirements listed under 33.852.105.H and 17.107.020, an applicant is required to develop a TDM Plan, get it approved based on the land use approval criteria, and then implement the approved TDM strategies at building occupancy.
