COLORADO SPRAWL IN THE NATIONAL AND GLOBAL CONTEXT

Sprawl Still a Problem After All These Years (and Americans and Coloradans Are Still Concerned)

By 2017, according to the most recent iteration of the National Resources Inventory (NRI), some 116,303,000 acres of land – 181,723 square miles – in the United States had been developed. This is an area nearly 20,000 square miles larger than the state of California (163,700 square miles), our third largest state. Only Alaska and Texas are larger. Another way of conveying the comparative extent of this developed land area is that it is approximately equal to the states of Maine, New Hampshire, Vermont, Massachusetts, Connecticut, Rhode Island, Delaware, New Jersey, New York, and Pennsylvania combined, that is, all of New England and much of the Mid-Atlantic States.

In the 35-year (1982-2017) period measured by the most recent National Resources Inventory (NRI), conducted by the United States Department of Agriculture’s (USDA) Natural Resources Conservation Service (or NRCS, formerly the Soil Conservation Service or SCS), approximately 69,000 square miles (44,175,300 acres) of open space, natural habitats, and farmland in the United States were converted into “Developed Land,” including housing, shopping malls, streets, schools, government buildings, utility infrastructure, waste treatment facilities, parking lots, vacation homes, resorts, highways, and places of work, worship, and entertainment. An area larger than Florida, our 22nd largest state, was “paved over” in just 35 years.

Which states have sprawled the most in recent decades? Texas, Florida, North Carolina, Georgia, and California are the top 5 sprawlers. Texas alone sprawled over 6,630 square miles in this time period, 52% more than the second-place state, Florida. Texans have witnessed and experienced this explosive growth firsthand. Colorado is ranked 21st nationally in terms of the amount of Open Space lost to urban sprawl and development from 1982 to 2017.
