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.

To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.

This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.

In fiscal year 2011, Chino Valley Unified School District’s student achievement was similar to peer district and state averages, and its operational efficiencies were mixed with some costs higher and some costs lower than peer districts’ averages. The District’s per-pupil administrative costs were slightly higher than peer districts’ because the District employed more administrative positions per pupil. The District’s plant operations, food service, and transportation programs operated reasonably efficiently, with cost measures such as cost per square foot, cost per meal, and cost per mile that were similar to or lower than peer districts’ averages. However, the District needs to improve controls over access to critical information systems and strengthen controls over its fuel purchase cards.

In fiscal year 2011, Elfrida Elementary School District’s student AIMS scores for reading and writing were similar to the peer districts’ averages, and its math scores were lower. The District’s operational efficiencies compared favorably to peer district averages in most areas. All of the District’s nonclassroom areas operated with lower per pupil costs than peer districts’ averages and were reasonably efficient overall considering the District’s small size. However, the District’s transportation cost per mile was 59 percent higher than the peer districts’ average, partly because of slightly higher staffing levels. Providing transportation services cooperatively with neighboring districts could help bring costs closer to the peer district average. Further, the District needs to strengthen its accounting and computer controls.

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.

In fiscal year 2011, Pearce Elementary School District’s student AIMS scores were similar to peer districts’ averages. Although per pupil costs were high in some operational areas, the District was reasonably efficient overall. Pearce ESD’s per pupil administration costs were similar to the peer districts’ average, and although its plant operations, food service, and transportation program operated with higher per pupil costs than peer districts, these areas operated in a reasonably efficient manner considering factors such as the age of the District’s buildings, number of meals served, and transportation miles driven. Although relatively efficient, the District should strengthen some of its accounting controls, including ensuring proper separation of duties for its payroll and purchasing processes and ensuring purchases are properly approved before they are made. The District should also strengthen some of its computer controls, such as the requirements for network passwords.
