The purpose of this paper is to provide background information on trends and possible future changes in urban structure and lifestyles important for planning the development of a parcel of Arizona state trust land known as Superstition Vistas (SV). This parcel, which is located just south of the Superstition Mountains in Pinal County, has an area of 275 square miles—enough land to provide housing for 900,000 new Phoenix metro-area residents at current population densities.

The aspects of future urban living discussed in this paper are those important for land-use planning—density, neighborhood design, transportation demand, etc. Very little attention will be given to the interior of homes. Also, since the SV parcel is currently undeveloped, emphasis will be placed on changes in urban structure that can be accomplished in greenfield developments rather than the in-fill of urban cores.

Arizonans have been divided in their feelings about growth and what to do about it, especially during the past two decades. To complicate matters, the debate over the best responses to growth has been drawn along overly simplistic lines—the economy versus the environment. Arizonans who follow the myriad issues related to urban growth closely are becoming convinced that the discussion needs to be recast in a new light.

Scholar Leo Marx coined the phrase “the machine in the garden” in 1964 to describe the relationship between nature and technology. Considering much of the writing about Arizona’s growth, it seemed an apt title for this volume of Arizona Policy Choices. "The Machine in the Garden" presents growth policy choices for Arizona along a continuum: Yesterday’s Growth—the policies that have been used in the past; Today’s Growth—the “smarter” approaches from around the country; and Tomorrow’s Growth—cutting edge thinking about the economy and experiments in urbanism and governance.
