Pima County, Arizona, has made a concerted effort in recent years to improve how it uses land and maintains its infrastructure.

The County already is already working to improve the area’s zoning codes, and the Sonoran Desert Conservation Plan, which works to balance development with preserving open space, has been touted as “one of the best and most comprehensive habitat conservation plans in the country.”
