District boundaries stretch from the Jackson County line in the west, to the Weld County line in the east. The northern boundary is the Wyoming state line, while the southern boundary passes roughly between the cities of Loveland and Fort Collins. As it runs west to east between the cities, the boundary follows County Road 32 until it reaches County Road 9. At that point, the boundary drops south one mile to County Road 30 before continuing east to Weld County.
Included within the district are the cities of Fort Collins, Timnath, LaPorte, Wellington, Bellvue, Livermore, Red Feather Lakes and Virginia Dale. The mountain communities of Stove Prairie, Poudre Park, and Rustic also all fall within the district, while Masonville, Drake, Glen Haven and Estes Park do not. Loveland and Berthoud are also outside of the district.
