The corridor adjacent to it is also the core of planned growth for the City of Aurora, to Denver's East, whose Southern expansion through annexation was thwarted by the formation of the City of Centennial.
Aurora's planning department this summer identified almost 40 developments either under way or on the drawing board along the fast-growing E-470 corridor.
Taken together, the developments represent an area the size of Lakewood.
When built out, the developments represent 69,286 housing units, where an estimated 180,170 people could live, increasing the city's population by almost 65 percent.
In today's dollars, that conservatively represents $20 billion in new residential construction.
It may take 40-50 years for all of the projects to be built out, however. The area of the developments, according to a print edition of a map in the hard copy Rocky Mountain News, is about 26 square miles (the article text, however, states that the area is comparable to the Lakewood, Colorado's area which has 144,000 people in 45 square miles). In other words, while they are hardly the utopian New Urbanist communities that many urban planners would like, it is also pretty dense for suburban development. Certainly, these are not ex-urbs (often defined as properties with 2 to 5 acre or larger average lot sizes, which translates into under 1,000 people per square mile or less).
The details, as in anyh long range plan, are conceptual, but this is a place to look as one looks to the future of the Denver metro area's growth.
