Geography

Gunbarrel is northeast of the city of Boulder proper, separated by a buffer area of private agricultural lands and publicly owned open space. The buffer areas provide over two miles (3 km) of separation over changing elevations. This reduces the impact of the Boulder Municipal Airport and the Boulder County Sheriff’s Department facilities (including the county jail), which are located on the southern side of the buffer.

Two reservoirs operated by the Boulder and Left Hand Irrigation Company are located in central Gunbarrel. Irrigation ditches and canals, including the Boulder and Whiterock Ditch, pass through this primarily residential area. The Twin Lakes Open Space, a large park which includes the two reservoirs and extends west along the ditch, is operated by the Boulder County Parks and Open Space Department. The park brings protected wetlands, jogging trails and green spaces directly into the urban area. The City of Boulder operates Eaton Park, adjacent to the west lake. Eaton Park includes picnic facilities, BMX jumps and additional protected wetland. Flood control facilities are integral to the reservoir and canal systems, but they do not eliminate the flood risk to adjacent development.

The Gunbarrel CDP has an area of 4,038 acres (16.340 km), including 38 acres (0.155 km) of water.

Natural hazards

The principal natural hazard in Gunbarrel is flooding. The county Transportation Department provides floodplain information through an online request page, free of charge for property owners in the unincorporated areas of the county, including Gunbarrel. Boulder County participates in the National Flood Insurance Program which allows some reduction in the cost of flood insurance for residents.
