Provides basic information about the source of surface water in Cienega Creek at the downstream end of the natural preserve, which will contribute to efforts to conceptualize and implement effective land management proposals for the SDCP. Study results indicate that the surface flow or subflow from Agua Verde Creek do not significantly influence the water in the Cienega Creek.

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.

“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.
