Chapman Drive was built by the Civilian Conservation Corps (CCC) in 1935 as a way to link Flagstaff Road with Boulder Canyon. There are a number of interesting historic rock walls and structures along the way, including a switchback and cattle guard, both of which were rehabilitated in 2012 with Colorado Lottery funds. Chapman Drive is included in the Boulder County Flagstaff Mountain Cultural Landscape District.
