"This guidelines and procedures manual is intended to be used by the staff of the Arizona Department of Transportation (ADOT) and Arizona's regional transportation planning agencies, which include Councils of Governments (COGs), Metropolitan Planning Organizations (MPOs), and Transportation Management Areas (TMAs). In addition to outlining the guidelines and procedures for regional transportation planning functions, this manual provides an overview of the programs administered by the ADOT Multimodal Planning Division (MPD)."--Introduction, Page 1-1

The Multimodal Planning Division (MPD) of the Arizona Department of Transportation has been tasked with identifying corridors throughout the state where improvements to the transportation infrastructure supports the greatest potential commercial and economic benefits. These "Key Commerce Corridors" represent a strategic statewide approach to leverage infrastructure improvements to enhance Arizona's competitive economic position. This document presents the basis for the identification and evaluation of the Key Commerce Corridors.

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.
