Transportation Demand Management (TDM)

Transportation Requirements for New Developments

The TDM Regulation(PDF, 451KB) is in effect as of June 1, 2021.  All new Site Development Plans (SDP) submitted to Community Planning and Development (CDP) must now include a TDM plan.

To create your TDM plan, see the “Compliance Documents" section of this webpage, or the Site Development Plan Review page for the TDM Compliance Spreadsheet. 

Background: Denver’s Departments of Transportation & Infrastructure (DOTI) and Community Planning and Development (CPD) have adopted new rules that make developers partners in furthering Denver’s mobility goals by providing residents and employees with choices in how they move about the city. The regulations require new developments to implement measures known as Transportation Demand Management (TDM) strategies that expand people’s travel options and create attractive alternatives to driving.

Benefits, Strategies & Goals

Denver’s TDM Plan will benefit the community by

  • Reducing the number of people driving
  • Creating walkable, transit-friendly communities
  • Improving community health and the environment

Developers will select strategies that expand people’s transportation options, including:

  • Services
  • Infrastructure
  • Parking Management
  • Multimodal Subsidies
  • Education

Examples of TDM strategies that developers may choose from to increase mobility options and reduce single occupancy vehicle trips, which contribute to traffic congestion and greater levels of greenhouse gas emissions include: 

  • Offering subsidized transit passes
  • Supporting/offering car share opportunities
  • Offering people who walk or bike to work amenities such as showers, lockers, and changing rooms
  • Shared amenities for people who ride bikes, such as repair kits and air pumps
  • Event or one-time transit passes or a transit validation program
  • Eliminating policies/practices that subsidize parking and incentivize driving
  • Work from Home and alternative work schedule policies 

The measures Denver will require of developers will correspond to the size of the development (by number of residential units or square feet of space), as well as the type of development and land use context.

Compliance Documents and Resources

The TDM Regulation has been seamlessly tied to the SDP review process, and creating the TDM Plan is a simple step in preparing your SDP for submittal. Any property submitting a Site Development Plan must also include a TDM plan. Here are the steps to get approved:

  1. Plan: Download the TDM Compliance Spreadsheet(XLSX, 219KB). (The spreadsheet is also found on the Site Development Plan Review website).
  2. Complete: The TDM Compliance Spreadsheet will prompt you for your project information, guide you through the TDM requirement, and present TDM strategies for you to choose from to comply with the requirement. When complete, the spreadsheet will produce a Summary Page that will constitute your TDM plan.
  3. Submit: Upload the TDM Summary Page (your TDM Plan) with your SDP submittal to CPD.
  4. Approval: DOTI will review and approve your TDM plan with the SDP. You will be provided you with comments if necessary, as part of the typical SDP review process.
  5. Assign: Assign a Transportation Coordinator (also called a TDM Contact) for the property. This should be someone who is familiar with the property and the approved TDM Plan. Contacts should be assigned before a Certificate of Occupancy is issued. If a TDM Contact is not identified the applicant and owner (as noted on the SDP application) will be the interim TDM Contact until another person is identified.
    Submit or Update a TDM Contact
  6. Construct: Any TDM infrastructure identified in the approved TDM plan will also be noted on the building permit set, and checked during typical construction inspections.
  7. Report: Properties will need to demonstrate annually that programmatic elements are being implemented and infrastructure is maintained. Larger properties will also need to conduct surveys to show progress toward their goals biennially.
