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.

This report is one of several from Statistical Research Inc. written to develop the Cultural and Historic Resources Element of the Sonoran Desert Conservation Plan. Divided into four parts, the report summarizes available information that reflects the experience of (1) ancient peoples of Southern Arizona; (2) indigenous peoples; (3) non-indigenous peoples of the historical period; and (4) Pima County today.

The depiction of a historical-period property on an early map, whether a house, a ranch, a mining prospect, or an irrigation canal, is often the earliest (and sometimes the only) evidence that cultural features once existed in a particular place. Statistical Research used early maps as a regional preservation-planning tool by systematically examining a group of early maps of the county for depictions of cultural features. The typology will be used to plot the sites, distinguished by type, on a single map (or possibly on a series of maps) to be digitized by Pima County and incorporated into its GIS database.

This study covers the time period after 1200 A.D. in terms of the domestic landscape, the agricultural landscape, and the social landscape as the residents of southern Arizona adjust to upheaval and change in environmental and social conditions. This memorandum summarizes the study about the Classic Period and provides a comparison of findings and theories about area residents from both before and after 1200 A.D., which is the approximate time frame of the collapse and restructuring of cultural landscapes.
