Transportation Department

The Former Transportation Department is now Community Planning & Permitting and Public Works

In January of 2020, Boulder County reorganized transportation and land use planning, among other restructuring. The changes involved:

    • Combining the Transportation Department’s engineering, fleet, and road maintenance functions with other operational and structural services of the county, such as the Boulder County Recycling Center and Building Services, into a new Public Works Department.
    • Grouping together similar planning and permitting services that formerly existed in two separate departments – Land Use and Transportation – and moving them to a newly named Community Planning & Permitting Department, formerly known as the Land Use Department.
