This manual provides an overview of Sections 404 and 401 of the Clean Water Act as they apply to Arizona Department of Transportation activities. Compliance with Sections 404 and 401 is necessary for Arizona Department of Transportation activities that involve the discharge of dredged or fill material into waters of the United States. The manual also provides general guidance on the preparation of jurisdictional delineations, Nationwide Permit Pre-Construction Notification submittals, and Individual Permit applications.

The long-term trend toward lower-quality jobs in the United States continued between 2001 and 2004. Industrial job quality fell 1.6 percent nationally between 2001 and 2004. The decrease in occupational job quality was not quite as great at 0.9 percent. Thus, overall U.S. job quality dropped 2.5 percent during the three years, causing the U.S. average wage to be 2.5 percent less than it otherwise would have been. Arizona’s job quality fell between 2001 and 2004 at a pace worse than the national average. Relative to the national average, the industrial and occupational job mixes each slipped a bit more than 0.3 percent during the three years, for an overall decline of 0.7 percent. In Arizona, job quality in 2004 was 2.0 percent below the national average, but Arizona ranked 23rd among all states.

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.
