A landmark assessment of infrastructure needs in Arizona was produced by the L. William Seidman Research Institute in May 2008 for the Arizona Investment Council (AIC): "Infrastructure Needs and Funding Alternatives for Arizona: 2008-2032", that addressed infrastructure needs in four categories: energy, telecommunications, transportation, and water and wastewater. The information from the AIC report is a major input to the report that follows. Other types of infrastructure — most notably education, health care, and public safety — also are analyzed here to provide a more complete picture of infrastructure needs in Arizona. The goals of this report are to place Arizona’s infrastructure needs into national and historical contexts, to identify the changing conditions in infrastructure provision that make building Arizona’s infrastructure in the future a more problematic proposition than in the past, and to provide projections of the possible costs of providing infrastructure in Arizona over the next quarter century.

The condition of Arizona’s infrastructure has a direct impact on economic productivity and quality of life. As economic competition expands domestically and globally, and as the knowledge economy evolves, the importance of a strong infrastructure increases. Education, in particular, is of growing importance. Arizona’s infrastructure challenges will require commitment and creativity to meet the needs and potential of 10 million people and to ensure a positive future for the state.

The primary purpose of this study was to develop a plan that enables the Town to facilitate safer and more efficient infrastructure for the traveling public and guide the development of the Business District. This study recommends phased improvement projects to address the multimodal transportation needs of the community, while steering community development and project funding. The study findings will also be incorporated into the Town's Capital Improvement Planning process for the next 5-, 10-, and 20-year time frames.

The Town of Superior Small Area Transportation Study was initiated by the Town of Superior in conjunction with the Arizona Department of Transportation. The purpose of this study is to document existing roadway characteristics and operations, land use and socioeconomic conditions, and other existing transportation modes, and to craft a long-range transportation plan to meet the transportation needs of the Town of Superior. A travel demand model was prepared to forecast traffic volumes to assist in identifying the traffic impacts with the anticipated growth in and around the City.

The purpose of the Verde Valley Multimodal Transportation Study is to develop a long-range regional transportation plan to guide the implementation of transportation improvements on the roads of regional significance in the Verde Valley, including I-17, State Routes, and roads on the County Regional Road System. This Study is an update of the 1999 Verde Valley Transportation Study Update.
