Coal Creek, commonly known as Coal Creek Canyon, is an unincorporated community and a census-designated place (CDP) located in Jefferson, Boulder, and Gilpin counties, Colorado, United States.[5] The population of the Coal Creek CDP was 2,494 at the United States Census 2020.[3] The unincorporated community is a part of the Denver-Aurora-Greeley, CO Combined Statistical Area and the Front Range Urban Corridor.

History

[edit]

The Coal Creek, Colorado Territory, post office operated from April 9, 1864, until October 29, 1873, but the Golden, Colorado, post office (Zip code 80403) now serves the area.[4][6]

Geography

[edit]

The Coal Creek CDP has an area of 6,018 acres (24.355 km2), including 9.6 acres (0.039 km2) of water.[2]

Public Transportation

[edit]

From the 1990s through the early 2010s, Coal Creek Canyon was served by a limited commuter transit route operated by the Regional Transportation District (RTD). The service, known as Route CC, connected residents of the canyon to the Olde Town Arvada Park-n-Ride, with Park-n-Ride stops at Wondervu, the Coal Creek Canyon Improvement Association, and at the junction of State Highways 72 and 93.[7]

Around 2010, due to low ridership RTD transferred operations of the route to Boulder County, rebranding it as the Coal Creek Express (CCE).[8] Despite reduced costs and efforts to expand ridership—including a proposed extension to Nederland in 2011[9]—the service was discontinued during RTD’s 2012 system-wide service reductions.[10] Currently no fixed-route public transportation operates in Coal Creek Canyon.

Climate

[edit]

According to the Köppen Climate Classification system, Coal Creek has a warm-summer humid continental climate, abbreviated "BSk" on climate maps, but closely borders on an oceanic climate (Cfb).
