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.

Wilson & Company recently completed the City of Casa Grande Small Area Transportation Study. The SATS notes that “as the City of Casa Grande increases in size and planning area, the roadway network is also growing to meet the additional travel demands significant improvement measures are needed to meet the travel demand generated by forecast population and employment growth”. Given the findings of the SATS, the City of Casa Grande contracted with TischlerBise to calculate an infrastructure improvement plans and updated development fees for transportation.

The City of Casa Grande engaged TischlerBise to update its Infrastructure Improvements Plans and development fees for several categories of necessary public services. TischlerBise previously calculated development fees for the City in 1999, 2003, 2006, and 2008. Municipalities in Arizona may assess development fees to offset infrastructure costs to a municipality associated with providing necessary public services to a development. The development fees must be based on an Infrastructure Improvements Plan. Development fees cannot be used for, among other things: projects not included in the Infrastructure Improvements Plan, projects related to existing development, or costs related to operations and maintenance.

Pima County’s Southwest area has been identified by County planners as a potential and strategic growth area. To accommodate population growth, the existing infrastructure must be improved and expanded. The purpose of this Infrastructure Plan is to provide a basis for infrastructure decision-making related to development in the Southwest area. It quantifies the nature, phasing, financial impacts, and funding possibilities for those flood control, parks and recreation, transportation, wastewater infrastructure and other improvements that are necessary to service future saturation growth within the study limits.
