The Cochise County Comprehensive Plan adopted in 1984 and last revised in 2011 serves to promote orderly and well-planned County growth. The Plan consists of a written document establishing land use, transportation, water conservation and public facility goals and polices and a series of maps that serve as a blueprint for the intensity and type of land uses expected near the incorporated cities and towns and in the outlying rural areas. Community and area plans are amendments to the Comprehensive Plan that address the future growth of a specific community or region of the County. They offer an opportunity for citizens who live and work in an area to have voice in the location, type and intensity of growth in their community. These plans based on long discussion with the community are designed to support land uses that enhance and protect an area’s unique character.

The purpose of this study is to build an econometric and demographic model of the Sun Corridor to forecast long-term economic and demographic conditions in the “megapolitan” region. To this end, the study examines the long-term economic and demographic forces that could affect economic development in the 3-county Sun Corridor megapolitan area that includes Maricopa, Pinal and Pima Counties. This information is used to develop a set of realistic economic/demographic scenarios to drive the forecasting model.
