Thornton's Long Range Planning Division
Thornton is one of the fastest growing cities in Colorado and shows no sign of slowing down. Thoughtfully addressing change and growth in a city of 150,000 residents is crucial to maintaining the high-quality services and amenities that draw people to Thornton. The Long Range Planning Department collaborates with the community and City Council to guide the city’s land use, identify historic resources, and analyze trends within the city and the region.
Planning Documents
Plans are the tool the Long Range Planners most frequently utilize to guide effective decision-making within the city and define the community’s vision for Thornton. Plans can cover different geographical areas, like the area surrounding an N-Line Station, or they can address certain types of resources in the city, such as the Transportation and Mobility Master Plan.
Plans are not law, but they serve as the basis for city decision-making and prioritization while providing the foundation for more regulatory documents like the city’s Development Code. Visit the Plans page or view different types of Long Range Planning documents below.
Other Long Range Planning Initiatives
In addition to Plans, Long Range Planning leads initiatives around Historic Preservation as well as Population & Demographic reporting.
