Stapleton area was once the main airport for Denver.
“While Denver International was being constructed, planners began to consider how the Stapleton site would be redeveloped. A private group of Denver civic leaders, the Stapleton Development Foundation, convened in 1990 and produced a master plan for the site in 1995, emphasizing a pedestrian-oriented design rather than the automobile-oriented designs found in many other planned developments. Nearly a third of the airport site was slated for redevelopment as public park space.
The former airport 4,700 acres (19 km2) site 10 minutes from Downtown Denver is now being redeveloped by Forest City Enterprises new urbanist project. Construction began in 2001, and as of 2008, 3,200 single-family houses, row houses, condominiums and other for-sale housing as well as 400 apartments had been built. The new community is zoned for residential and commercial development, including office parks and “big box” shopping centers. Stapleton is by far the largest neighborhood in the city of Denver and an eastern portion of the redevelopment site lies in the neighboring city of Aurora, Colorado.”
