The Arizona Department of Transportation, in coordination with Apache County District II and the Fort Defiance Chapter of the Navajo Nation, analyzed the traffic circulation conditions of Navajo Routes 7, 12, 54, 110, and 112 within the Fort Defiance Industrial Area which is designated as a major growth area on the Navajo Nation. The study was funded by the Federal Highway Administration’s State Planning and Research Program and administered through ADOT’s Multimodal Planning Division's Planning Assistance for Rural Areas (PARA) program. The study was initiated to develop a planning strategy to improve the mobility and safety within the Fort Defiance Industrial 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.

Given the inevitable transportation changes associated with impending growth in Pinal County, there was a need for a method to assess how corresponding emissions changes might affect PM10 and Ozone concentrations in the county and at the monitor sites. The overall objective of the project was to develop methods or models that could be used in Pinal County to adequately address air pollution issues in the County.

This report and the accompanying Geographic Information System (GIS) datasets summarize the results of the workshop held in Florence, Arizona in 2010. At this workshop, stakeholders representing a broad range of organizations and interests identified and mapped the locations of important wildlife linkages across Pinal County. This report provides background information on the importance and benefits of conserving wildlife linkages for both people and wildlife in Pinal County and describes the methods used during stakeholder workshops and in developing the accompanying GIS products. It includes a series of maps generated from the digitized stakeholder data that depict the general locations of wildlife linkages and potential barriers to wildlife movement within Pinal County. The maps are followed by tables with descriptive information about the habitat areas each linkage connects, the species each linkage serves, and known threats and potential conservation opportunities associated with each linkage.

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 describes the development of base and future socioeconomic estimates for the Pinal Corridor Planning Model, developed by ADOT to support the evaluation of potential new highway corridors in Northern Pinal County. This section presents a summary of the methodology, data sources used, and historical trends in population and employment growth. The following two sections present the base and future year methods and resulting estimates of population and employment.

In September 2004, ADOT awarded a contract for the Pinal County Corridors Definition Study to Kimley-Horn and Associates. The scope of the Pinal County Corridors Definition Study included the following activities:
* Confirm the need for the East Valley and the North-South corridors;
* Define planning-level corridor definition alternatives;
* Perform a technical assessment of engineering, environmental, and land use compatibility constraints opportunities for the planning-level corridor definition alternatives;
* Identify to the extent possible, feasible and preferred planning-level corridor definitions on the basis of the technical evaluation;
* Document planning-level costs of corridor development (including studies, design, construction, and right-of-way costs) for the preferred corridor definitions.

The Pinal County Corridors Definition Study resulted in sufficient detail to provide a basis for the future establishment of geometric roadway alignments and corridor design concepts, the preservation of right-of-way, and the identification of required environmental clearance studies.

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.

The proposed Meridian Road Corridor Study is needed to support the continuing development and growth, occurring and anticipated, in the East Mesa, West Apache Junction, and within Pinal County. The purpose of the Meridian Road Corridor Study is to document conditions along the existing roadway and to develop alternatives that will increase the safety and future level of service of Meridian Road. This study will also establish a roadway footprint and develop the ultimate right‐of‐way requirement for the corridor. Finally, the study will be utilized as a guide for local agencies and future development along the corridor. The study area for the Meridian Road Corridor Study is approximately 13 miles in length.

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.
