The Office of Highway Safety produces the annual Highway Safety Plan to serve as the implementation guide for highway safety projects throughout Arizona. The Plan also is an application for funding through the National Highway Traffic Safety Administration. Project selection is data driven and utilizes state and national traffic safety data (e.g., crashes, fatalities, injuries, citations, etc.). Knowledge of the Arizona political, economic, and demographic environments, as well as highway safety expertise on the part of staff and other partners also are taken into account where appropriate.

This study, and the resulting transportation plan, is funded through ADOT’s Planning Assistance for Rural Areas (PARA) program. ADOT and the Town of Colorado City have retained the consultant team of Wilbur Smith Associates to conduct the study under the oversight and direction of a Technical Advisory Committee (TAC) that includes members from the Town of Colorado City; adjacent Hildale City, Utah; Mohave County; the Arizona Department of Transportation Multimodal Planning Division; the ADOT Flagstaff District Engineer’s office; and other interested parties.

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.

From May 2005 to June 2005, the Arizona Department of Environmental Quality conducted a study, Potable Well Sampling Task 4.0, to determine if the chromium and chromium VI plume due to the discharge of the Pacific Gas and Electronic Topock Compressor Station has migrated under the Colorado River and impacted water supplies in Arizona. The ADEQ investigated the total chromium and hexavalent chromium (chromium VI) concentrations in (1) public water supply wells, (2) combined industrial and domestic water supply wells, and (3) private domestic water supply wells at Topock and Golden Shores, Arizona. The communities of Topock and Golden Shores have expressed their concerns regarding the findings. Thus, the ADEQ requested the Arizona Department of Health Services to evaluate the potential health effects of exposure to well water contaminated with chromium.

Grace Neal Parkway and Bank Street are located in the northern Kingman area partially outside of the Kingman city limits. This report discusses of creating a new arterial roadway providing safety and convenience for vehicular traffic and pedestrians. Although Grace Neal is referred to as a parkway, its designation for design is arterial.

It was decided to revise the 1980 Havasu area study, since the area had changed so much. The members felt that to retain some control over the growth a revised area plan was needed and decided to have the area covered to be just the 72 square miles of the Desert Hills Fire District, rather than the whole of the unincorporated Lake Havasu Area north of the City.
