Countywide Transportation Sales Tax Projects

Countywide Transportation Sales Tax Projects

In 2007, Boulder County voters passed a countywide ballot issue to extend an existing one-tenth-of-one-percent sales tax from July 1, 2009 through June 30, 2025. The Countywide Transportation Sales Tax funds a specific list of 44 projects that includes:

  • 10 roadway improvements
  • 13 road shoulder projects
  • 6 transit projects
  • 1 Transportation Demand Management (TDM) program
  • 5 pedestrian improvements
  • 9 countywide regional sales projects.

The 2007 Ballot Issue lists five categories of projects in order to provide taxpayers with a wide range of improvements geographically and by type. Fifteen percent of the funds are fiscally separated out for use on Regional Trail connections. Another fifteen percent were allocated to projects and programs that helped the regional transit and travel demand management (TDM) for county residents. The remainder of funding was distributed to road and shoulder improvements and pedestrian access and safety projects.

2020 marks the 11th year of the 15-year Countywide Sales Tax approved by voters in November 2007. The table below identifies current countywide Transportation Sales Tax projects planned for construction over the next three years. A full implementation schedule for all projects is available here. Projects are listed by anticipated year of implementation based on the best available information. Ongoing transit projects are listed separately at the bottom of the table. These projects use Countywide Sales Tax to increase frequencies on existing regional routes.

The April 2017 Countywide Transportation Sales Tax Update includes:

  • An overview of the program
  • An analysis of milestones
  • Recommendations for the remainder of the program
