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.

Some of the richest helium-bearing gas in the world was produced in Arizona. Helium concentrations range from trace amounts up to ten percent in the Holbrook Basin and Four Corners. Both areas have good potential for additional discovery and production of helium. Includes metadata for the monthly, annual, and cumulative summary reports of oil, gas and helium production by Arizona drilling fields.

MGT of America, Inc. was retained to conduct a study for the Arizona Department of Transportation to determine whether there was a compelling interest to justify a disadvantaged business enterprise program for ADOT. MGT found that minority, women and disadvantaged business enterprises were substantially underutilized as prime contractors in construction and construction-related professional services. African American, Hispanic American, and Asian-owned firms were under-utilized as construction subcontractors. The study provides factual predicate evidence for the selective use of project goals for African American, Hispanic American, and Asian American construction subcontractors.

The purpose of this research project is to determine the origin of the materials used to construct the Black Hills Dam in order to restore the landscape to pre-dam conditions. The Black Hills Dam site is located in northern Scottsdale, Maricopa County, at 33.75° North, 111.80° West. The goals of this project are to characterize the surficial deposits and local geology of the dam site. This report presents our findings, interpretations and conclusions based on background research, a site visit to the dam site, and technical discussions with the City of Scottsdale engineer and planners.

This open-file report describes the carbon-sequestration potential at the site of the 1 Alpine-Federal geothermal test drill hole, which is located south of Springerville in central eastern Arizona near the New Mexico border. A previous report, Arizona Geological Survey (AZGS) Open-File Report OFR 94-1, version 2.0, describes the subsurface geology encountered in the 1 Alpine-Federal well in much more detail than this new report.

There are two distinct components to the economic development activities described in ADOH’s LIHTC program details. The first component is activity that strengthens the economy. This is the quantifiable activity that is the subject of this report. The second component is community building activity which can be both quantitative and qualitative. This is an area that should be considered in the debate but which is not addressed within this report.

This report details geothermal resource exploration done for Arizona Public Service and the U.S. Department of Energy in 2005 to evaluate the geothermal resources of the Clifton Hot Springs area in Greenlee County, eastern Arizona for electric power production. The intent of the evaluation was to determine the local geologic controls of the geothermal system and, using publicly available data and original mapping performed for this project, to recommend locations for Controlled Source Audiomagnetotelluric (CSAMT) cross sections. The results of the geophysics were then combined with the geologic mapping to site three gradient holes, two of which were drilled to depths of 635 feet and 1,000 feet, respectively.
