Arizona is one of the nation’s most urban states, and now it includes one of 20 “megapolitan” areas in the U.S. People have predicted for 50 years that Phoenix and Tucson would grow together into a giant desert conglomerate. That possibility has been seen as exciting, intriguing, and distressing. While a solid city along Interstate 10 is unlikely given the diverse land ownership in central and southern Arizona, the two metro economies are already merging.

Megapolitan: Arizona’s Sun Corridor, one of the first reports on a single megapolitan area, recognizes a more sophisticated technique for analyzing urban growth—that shared economic and quality of life interests are more important than physically growing together.

Scholars at Virginia Tech defined the megapolitans based on economic and growth patterns.
The Sun Corridor, which cuts across six counties from the border with Mexico to the center of Yavapai County, is the home of eight out of 10 Arizonans. In the next several decades, two out of three Americans will live in a megapolitan accounting for 60% of the population on only 10% of U.S. land.

Megapolitan offers a bold new picture of Arizona’s geography and its future opportunities and “megaton” challenges. This report presents a scenario for 2035 based on current trends. It analyzes the Sun Corridor and provides insights into the region’s global potential, water, governance, sustainability, and “trillion dollar questions.” It discusses the “tragedy of the sunshine” and asks the indispensable question: In 2035, do you want to live in the Sun Corridor?

“What about the water?” was one of the questions Morrison Institute for Public Policy asked in its 2008 study, "Megapolitan: Arizona’s Sun Corridor". That report looked at the potential growth of the Sun Corridor as Tucson and Phoenix merge into one continuous area for economic and demographic purposes.

With its brief review of the water situation in urban Arizona, "Megapolitan" left a number of questions unanswered. This report will consider questions like these in more detail in order to examine the Sun Corridor’s water future. This topic has received less sophisticated public discussion than might be expected in a desert state. Arizona’s professional water managers feel they are relatively well prepared for the future and would like to be left alone to do their job. Elected officials and economic-development professionals have sometimes avoided discussing water for fear of reinforcing a negative view of Arizona. This report seeks to contribute to this understanding, and to a more open and informed conversation about the relationship of water and future growth.

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.

For most of the past 50 years, Pinal County hasn't had to think much about its image, choices, or growth. But now, Pinal County is changing faster than anyone ever imagined. Will Pinal become a distinguishable destination or simply a McMega drive through? If Pinal rises to the occasion, the result can be a vibrant, sustainable, and competitive place that takes advantage of its location. If Pinal fails to choose wisely, its bedroom community future is already visible in the East Valley and subdivisions north of Tucson. Which will it be?

When Arizona's economy depended on the 4Cs – copper, cotton, citrus, and cattle – Pinal County was a leader in 2 of them. These historic sources of wealth and touchstones of heritage still play a role in the county's economy, but dramatic population growth and new economic drivers make this a different, distinctive time. This new era demands new vision, new ideas, and new ways of thinking, even as past strengths are kept in mind.

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.

Four major statewide "tools" to help manage growth and preserve open space have been put to work in Arizona over the past five years. These include the Arizona Preserve Initiative and the closely-related Proposition 303, as well as the Growing Smarter Act and its "addendum," Growing Smarter Plus. All four tools are based in large part on a concept known as "smart growth," which is generally considered to be a set of growth management measures that attempt to strike a balance among issues of economics, environment, and quality of life. Taken together, these four growth management tools make significant changes in the way that (a) city and county governments plan and regulate their lands, (b) citizens play a role in land use issues, (c) state trust lands are managed, and (d) open space may be acquired and preserved. Many of these changes will have long-term effects for the state. This paper provides a brief overview of each of the four growth management/open space tools, a preliminary accounting of major activities each one has stimulated, and a perspective on what can be expected for the future as expressed by a selection of growth planners and other leaders of growth management in Arizona.

Fast Growth in Metropolitan Phoenix is the first product of a comprehensive effort to describe and analyze the region’s growth. The Brookings Institution Center on Urban and Metropolitan Policy in Washington, D.C. presented the opportunity for this project to Morrison Institute for Public Policy. The story of growth in metropolitan Phoenix is a complicated, often surprising, tale. There is much to be proud of in the region. Yet there is also much to worry about, and much that needs to be done. Hits and Misses will have been successful if it becomes a catalyst for getting started.

This publication offers comparative data and analysis on 10 public policy issues. With its scope and detail, "How Arizona Compares" will be of interest to many throughout Arizona and strives to encourage leaders and residents to discuss and move ahead on the state's most pressing public policy issues. The intent is for this publication to be studied and used for dialogue and action. The following sections are included: (1) Polishing the 48th Star; (2) Inside "How Arizona Compares"; (3) Arizona's Land and People; (4) Crime and Punishment; (5) Health and Health Care; (6) Education; (7) Business Futures; (8) Families and Incomes; (9) Signal Measures on Hot Topics; (10) Government; (11) Arts and Culture; (12) Housing; (13) Transportation; and (14) Environment. A list of selected sources is appended.
