Letter from Joseph J. Cotter to Carl Hayden detailing the approximate amount of patented land within the proposed borders of the national park. Thomas J. Croaff is mentioned in his belief that he owns half the land in the proposed area; however, Joseph J. Cotter disputes this claim. Ralph Cameron's mining interests in the park are also mentioned. Circa 1917.

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.

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.
