Transit and Active Transportation Project Inventory

This page gives an overview of Colorado's Senate Bill SB25-030: Increase Transportation Mode Choice and Reduce Emissions which requires the Colorado Department of Transportation (CDOT), metropolitan planning organizations (MPOs), transit agencies, and local governments to work together to develop transit and active transportation project inventories. The page includes information on SB25-030's key requirements, deadlines and reporting requirements, and roles and responsibilities for CDOT, MPOs, local governments, and transit agencies.

Overview

On May 13, 2025, Governor Jared Polis signed SB25-030: Increase Transportation Mode Choice and Reduce Emissions into law. The law directs the Colorado Department of Transportation (CDOT), metropolitan planning organizations (MPOs), transit agencies, and local governments to work together to identify gaps in transit, bicycle, and pedestrian infrastructure across the state. The goal is to improve safety, connectivity, and access to non-driving transportation choices for Coloradans.

By July 1, 2026, CDOT and Colorado’s MPOs must each create a Transit and Active Transportation Project Inventory: a list of projects that improve connectivity and safety for people walking, biking, rolling, and taking transit.

Key Requirements of SB25-030

Transit and Active Transportation Inventories

  • CDOT must create a transit and active transportation project inventory for state highways and rights-of-way.
  • Each Metropolitan Planning Organization (MPO) must create a transit and active transportation project inventory for the regional network as defined by the MPO.
  • Projects included in the inventory are those that address gaps in transit, bicycle, and pedestrian infrastructure.
  • Projects may be unfunded or funded and do not need to meet any particular delivery timelines.

Deadlines, Reporting Requirements, and Ongoing Updates

  • December 31, 2025: Local governments with populations of 5,000 or more that are located within an MPO are required to submit planned transit, bicycle, and pedestrian projects that impact the regional network to their MPO. 
  • July 1, 2026: CDOT and MPO project inventories must be completed. 
  • October 31, 2026: CDOT and MPOs must report on the inventories and an assessment of existing and potential funding sources for inventory projects to the Transportation Legislation Review Committee.
  • CDOT and MPOs must use the inventories to inform regional and statewide transportation plans, transportation improvement programs, and transit service plans.
  • Inventories must be updated regularly as part of statewide and regional transportation planning processes.

Local Government And Transit Agency Roles

  • By December 31, 2025, local governments with populations of 5,000 or more that are located within an MPO are required to submit planned transit, bicycle, and pedestrian projects that impact the regional network to their MPO. 
  • MPOs will coordinate with transit agencies to compile planned transit projects.
  • By December 31, 2025, local governments and transit agencies located outside of MPOs are invited to submit their planned transit, bicycle, and pedestrian projects that impact the state highway network to CDOT.
  • Local governments and transit agencies located within the boundaries of an MPO can submit planned active transportation and transit projects to their MPO. Local governments and transit agencies located outside of MPOs can submit planned projects to CDOT. Local governments and transit agencies with both MPO and non-MPO areas should submit planned projects within the MPO area to their MPO and should submit planned projects in the non-MPO area to CDOT.
