One in a series of long-range transportation planning studies being conducted by the Maricopa County Department of Transportation to assess the ultimate corridor footprint requirements to enable consistent implementation across multiple jurisdictions. The study area for this project includes Peoria Avenue from the future Jackrabbit Trail Parkway alignment to Dysart Road (Peoria Avenue Corridor). The study area generally encompasses a two-mile wide corridor centered on the existing Peoria Avenue.

Apache County is required by state law to prepare a comprehensive plan “to conserve the natural resources of the county, to insure efficient expenditure of public funds, and to promote the health, safety, convenience, and general welfare of the public.” The planning process is structured to emphasize public involvement and incorporate comments, ideas, and direction of the public into the plan. This plan strives to create strong and vibrant communities within Apache County by encouraging orderly development.

This report describes a series of full-scale vehicular crash tests conducted to evaluate the impact performance of small sign supports used by the Arizona Department of Transportation (ADOT). The tests were conducted and evaluated in accordance with the recommendations of NCHRP Report 230 and the 1985 AASHTO "Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals."

Bellemont is a rural, unincorporated community with a population of approximately 1,000 residents in Coconino County that has become a suburb of Flagstaff, where residents commute to work. Three roads ó Interstate 40 (I-40), Brannigan Park Road and Shadow Mountain Drive ó are used to access virtually all the private land north of I-40 at Bellemont. Frequent congestion from heavy truck volumes and subdivision traffic causes traffic delays and creates concern for safety and timely emergency response. The 2008 closure of the ADOT Parks Rest Area on I-40, just west of Bellemont, has also increased vehicular traffic accessing the truck stop and restaurants. Future build-out of the subdivision and potential commercial/industrial uses in the area are expected to continue to negatively affect the Brannigan Park Road and Shadow Mountain Drive intersection and the I-40 traffic interchange. ADOT recently prepared the I-40 Bellemont to Winona Initial Design Concept Report, which recommended long-term improvements for the intersection and traffic interchange.

Ultimately, this access management and multimodal transportation study will provide a comprehensive review of the Bellemont area transportation system and provide guidance for determining priority needs for future improvements north of I-40, including alleviating congestion and improving/managing access, and improving and evaluating multimodal access to businesses from residential areas.

The 2009 Navajo Nation Long Range Transportation Plan is a twenty-year comprehensive plan developed and updated by the Navajo Division of Transportation in a five-year cycle. The plan identifies the Nation’s multi-modal transportation needs over the next 20 years and develops strategies to meet them. The plan provides long range planning policies and implementation strategies for the Navajo Indian Reservation Roads Program improvements. It is based on a comprehensive analysis of all pertinent factors and issues affecting the Navajo Nation’s existing and future transportation needs.

The Arizona Department of Transportation has been involved with railroad planning since 1976, with its first State Rail Plan Update issued in 1978. The most recent report, the 2000 Arizona State Rail Plan Update was an important starting point for this Inventory and Assessment in that the seven-year-old study provides the description and inventory of Arizona railroads as they existed at that time. There have been a number of important changes over the intervening years, and these are reflected in this 2007 Inventory and Assessment. In addition to the 2000 State Rail Plan Update, RLBA made use of the 2003 Maricopa Association of Governments (MAG) High-Capacity Transit Study and the 1998 Arizona High Speed Rail Feasibility Study. The information contained in this report was gathered from a number of sources, including the railroads themselves, ADOT, the Arizona Corporation Commission, MAG and numerous Arizona officials. A listing of persons who contributed to this Railroad Inventory and Assessment is provided under “Acknowledgements” inside the front cover. Information in this report also was obtained from the Association of American Railroads and from RLBA’s extensive data banks.

The Concho Community Plan is an expression of how the residents of our community wish to see our community grow, develop and prosper. The entire region is experiencing rapid growth. Rather than allow this growth to be haphazard or of low quality, the Concho Community Plan sets forth guidelines to assist in planning for orderly growth that meets its needs and standards. The Concho Community Plan addresses the current and future elements that the community indicated were the most pressing. It also utilizes the various established deed restrictions and proposes to base the zoning districts on them, thereby eliminating many conflicts and enhancing enforcement.

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.
