The State of the System Report is a compilation of the physical inventory and status of the Maricopa County Department of Transportation’s infrastructure. It addresses roadway congestion, traffic safety, low volume road paving, bridges, and pavement conditions. Also, included are recommendations for future improvements within each of the infrastructure categories. The SOS report has been produced annually since 1998.

This is Maricopa County's long-range plan for transportation. This plan was last produced in 1997. The Maricopa County Department of Transportation has undertaken the process of updating the Transportation System Plan because much has happened in Maricopa County since 1997. This updated TSP establishes an organized approach to the planning, design and construction of Maricopa County's transportation system through 2026.

For a century, Arizona has pursued prosperity through outward expansion of its urban areas. In metropolitan Phoenix and elsewhere, “growth” has meant developing raw land with new houses, new shopping centers, and new industrial parks--and the metropolitan “frontier” has moved farther outward from downtown every year. This has not been uniformly true, of course. Some cities--Phoenix, Tempe, and Scottsdale especially--have been grappling with the question of revitalizing older urban neighborhoods for many years. But the “outside game” has been the predominant development pattern in the Valley of Sun for many decades. And the Phoenix region has played this game better than one might think, creating many high-quality master-planned communities, protecting lots of open space, using impact fees to build good infrastructure. In other words, Phoenix has used the “outside game” to create a region so attractive it continues to be one of the fastest-growing metropolises in America. But in order for cities to play a good inside game, Arizona must get serious about urban revitalization. And that will require big changes.

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.
