The Arizona Department of Transportation, the Arizona Game & Fish Department and the Arizona State Parks Board are required to conduct a study every three years on watercraft fuel consumption and recreational watercraft usage. The fuel consumption data is collected to determine the allocation of motor vehicle fuel tax to the State Lake Improvement Fund. The information on recreational watercraft usage patterns on Arizona’s lakes and rivers is necessary, in part, to determine the distribution of SLIF funds to applicants.

This report describes the development of base and future socioeconomic estimates for the Pinal Corridor Planning Model, developed by ADOT to support the evaluation of potential new highway corridors in Northern Pinal County. This section presents a summary of the methodology, data sources used, and historical trends in population and employment growth. The following two sections present the base and future year methods and resulting estimates of population and employment.

In fiscal year 2012, Scottsdale Unified School District’s student achievement was similar to peer districts’, on average, but it compared less favorably in operational efficiencies. The District’s food service program operated efficiently with a cost per meal that was lower than the peer district average. However, the District’s administrative costs were higher than peer districts’, primarily because it employed more administrative staff. In addition, the District inaccurately reported its costs on its Annual Financial Report and it lacked sufficient computer controls. The District’s plant operations cost per pupil was higher than peer districts’, on average, because the District maintained more square footage per student than the peer districts’ and many of its schools operated far below their designed capacities. Further, the District’s transportation cost per mile was much higher than the peer districts’ average, in part, because of inefficient bus routes.

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.
