Geography
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
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
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).
