This research study addresses the collection, preparation, and use of traffic data required for pavement design by the Arizona Department of Transportation, focusing on data required as inputs for the American Association of State Highway and Transportation Officials "Mechanistic-Empirical Pavement Design Guide" design procedures. ADOT’s current traffic data collection and preparation processes are not adequate to meet the needs of the MEPDG procedure, and improvements are needed. These improvements include enhanced volume, classification, and weight data collection for vehicles, processing data and performing quality assurance checks, and the preparation/analysis of the data for use in the MEPDG. Use of the MEPDG in Arizona will require (1) an annual flow of updated key traffic data and (2) the ability to collect on-site (MEPDG Level 1) data in a timely manner for key projects.

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.

The Ganado-Burnside Area is a rural community located on the Navajo Nation in northeastern Arizona. Ganado was formally established in 1901 as the location for a Presbyterian Church Mission, a school and hospital. Later the community served as a center to distribute various types of Bureau of Indian Affairs services. Today, the community area serves as a major center for housing, education, health and government operations. Also in the Burnside area, the Ganado School District recently established a new high school and sports venue to accommodate track and field, baseball, and basketball activities.

There are four main roadway corridors that intersect the study area: State Route 264, US Route 191, Navajo Route 27 and Navajo Route 15. There are also county gravel roads and private and community dirt roads that intersect SR 264, the main traffic corridor. Within these routes there is substantial multimodal activity generated from the area schools, medical facilities, transit operations, government entities, utility providers and social programs. The principal focus of this study project is to address the most critical transportation planning needs identified by the Ganado Chapter and Apache County. This will include, but is not limited to, a comprehensive needs analysis of multimodal movements and traffic circulation as well as safety issues for the project area corridors. The major product of the study will be a final report, which contains a Plan for Improvements. Taking into consideration received public input, the Plan will span over five-, 10- and 20-year periods, incorporating both roadways and the multimodal needs of the area.

The Ganado-Burnside Area Traffic Circulation Study will also be conducted according to a cooperative planning process that involves stakeholders that include public agency staff, elected tribal officials and tribal community members. Throughout the study, information will be presented to and solicited from stakeholders through individual interviews and to the general public through public meetings and other means of communication.

Pima County is now finalizing the long-awaited Multi-species Conservation Plan, which, if approved by the U.S. Fish and Wildlife Service, will streamline public-sector and private-sector development compliance with the Endangered Species Act while protecting endangered species and their habitats. In the coming months, the public will have a chance to comment on the MSCP through the U.S. Fish and Wildlife Service’s formal public comment process before it goes to the County Board of Supervisors for final adoption.This report reviews the history of the MSCP, its relationship with the award-winning Sonoran Desert Conservation Plan, what benefits the MSCP will bring to the community, and what obligations the County, developers, and the taxpayers will have over time. The report also highlights other benefits of conservation actions undertaken by Pima County, including economic, recreation, and health benefits.

The purpose of this report is to highlight lands acquired with 1997 and 2004 voter-approved bond funds, provide a historical record of Pima County’s land conservation efforts and consider how these properties contribute to Pima County’s long-term vision – the Sonoran Desert Conservation Plan. The report also provides a special feature on the evolution of conservation and land use planning in Pima County.

While we may view climate change issues as a more global or national problem, our unique Sonoran Desert ecosystem is a recognized global resource; hence climate change is an important consideration in how we manage and protect our fragile desert ecosystem. This discussion is designed to promote local awareness of how climate change may impact our resources.
