This study focuses in the area surrounding the municipalities of: Town of Pima, City of Thatcher and City of Safford. The junction of the two major state routes, US 191 and US 70 is located in the heart of these communities and serves as major arterials for local travelers. Parsons Brinckerhoff has been commissioned by ADOT to perform this preliminary assessment for the development of an alternate route through the Thatcher/Safford/Pima area.

The San Xavier District of the Tohono O’odham Nation is home to approximately 2,000 people. Numerous others come to the District to visit the San Xavier del Bac Mission Church. The San Xavier District Pedestrian Access and Safety Study is being prepared to improve the walking and bicycling environment on the San Xavier District for Community members and visitors alike. The study is being funded by the Arizona Department of Transportation Multimodal Planning Division’s Planning Assistance for Rural Areas program.

The historical advantages of Grand Avenue and the railroad that led to the development of the West Valley cities have become a detriment to the further development or redevelopment in the past few decades. There is general agreement that significant improvements are needed for the Grand Avenue Corridor. Identified transportation funds provide an opportunity to develop a more modern transportation corridor along Grand Avenue. This study addresses these concerns by developing, evaluating, and recommending transportation investment options.

Following the completion of the 2005 report, an Act was passed that contained a number of important new and continued funding sources for safety related projects, programs, and initiatives. This required every state to develop a Strategic Highway Safety Plan. This 2007 report represents Phase 1, Development Plan and is a comprehensive, collaborative, high level, statewide safety strategy that will guide Arizona's safety change initiative. The Arizona Department of Transportation was assigned the role of project manager for this SHSP phase by the Governor's Traffic Safety Advisory Council.

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.
