An update to the Flagstaff Regional Plan 2030 (FRP30), to bring its Road Network Illustration (Map 25) into compliance with Arizona Revised Statute requirements and to resolve inconsistencies between Map 25 and parts of the Flagstaff City Code. This update does not alter the intent of FRP30; it is only concerned with correcting errors, removing legal vulnerability, and improving the readability of FRP30.

The objective of this study was to evaluate the effect of typical chemical winter maintenance practices on Arizona Department of Transportation pavements. A review of previous studies on the effect of deicing/anti‐icing chemicals did not yield definitive recommendations, especially for DIAICs typically used by ADOT. Researchers conducted a laboratory study evaluating the effects of magnesium chloride, potassium chloride, sodium chloride, and distilled water on eight different open‐graded rubber‐modified asphalt concrete mixes using the boiling test. All experimental factors were found to be statistically significant, and the researchers provide recommendations on which DIAICs should be used for different binder and aggregate types.

Land Use and Traffic Congestion is an investigation into the links among land use, travel behavior, and traffic congestion. Researchers focused on four transportation corridors in the Phoenix area: three older neighborhoods with relatively mixed, higher density land use, and one suburban area with lower density but high traffic volumes. The analysis suggested that the higher density corridors exhibited less congestion due to the greater mix of uses, shorter trip lengths, more travel by transit and non-motorized modes, and the presence of a secondary street grid system.

As part of the Long Term Pavement Performance (LTPP) Program, the Arizona Department of Transportation constructed eight Specific Pavement Studies 9 (SPS‐9) test sections on Interstate 10 near Phoenix is an overlay project and is accordingly given independent analysis and documentation in this report separate from Arizona SPS‐9B projects located on US 93, which were new construction and are documented in a separate report. The SPS‐9A project studied the effect of asphalt specification and mix designs on flexible pavements, specifically comparing Superpave binders with commonly used agency binders. Opened to traffic in 1995, the project was monitored at regular intervals until it was rehabilitated in 2005. Surface distress, profile, and deflection data collected throughout the life of the pavement were used to evaluate the performance of various flexible pavement design features, layer configurations, and thickness. This report documents the analyses conducted as well as practical findings and lessons learned that will be of interest to ADOT.

The Arizona Department of Health Services sponsored the development of this plan with the intent to set priorities and suggest strategies to address asthma as a serious chronic disease and public health issue. The plan continues the focus placed on asthma in the Healthy People 2010 report. The plan is meant to serve as an ambitious and comprehensive approach to improving the health and quality of life for those with asthma living in Arizona.

Adult tobacco use represents an important and ongoing morbidity, mortality and health care cost problem. The Arizona Department of Health Services Tobacco Education and Prevention Program has been working since 1996 to reduce tobacco use in Arizona. This report presents data from the 2005 Adult Tobacco Surveys in Spanish on adult tobacco use prevalence rates, cessation behaviors, and home smoking bans.

The Arizona Department of Health Services initiated the development of this plan with the intent to set priorities by formulating objectives and suggesting strategies to address chronic obstructive pulmonary disease as a serious public health issue in Arizona. This plan begins with a detailed description of chronic obstructive lung disease followed by a discussion of proposed objectives and strategies. The overriding goals of this plan are those stated in the Healthy People 2010: Objectives for Improving Health.

The Arizona Department of Health Services Bureau of Tobacco Education and Prevention began its strategic planning process in August of 2007 and aimed to create a model that focused on effective tobacco control which would engage stakeholders at the local, state and national levels. As such it was critical to ensure that the process was both transparent and participatory, and included input and involvement from the full diversity of populations and regions across Arizona.

This study investigated whether highways acted as barriers to gene flow for pronghorn in northern Arizona. DNA samples from 132 pronghorn were analyzed using eight polymorphic microsatellite loci. Samples represented animals living on opposite sides of US Route 89 (US 89) and State Route 64 (SR 64). Two different modeling approaches indicated that both US 89 and SR 64, and to a lesser extent US Route 180 (US 180), acted as barriers to gene flow. The genetic structuring caused by highways, especially across US 89, is consistent with behavioral data that demonstrated pronghorn rarely cross this highway. This study found no evidence of inbreeding or reduced genetic variation in any of the populations examined, but those effects may take longer to appear. Based on these results, the researchers recommend future genetic monitoring of these populations or assessment of genetic variation across highways with larger traffic volumes or longer histories to determine whether the barrier effects documented here lead to loss of genetic diversity.
