A comprehensive research program for the characterization of storm water runoff from an Arizona highway was conducted from January through December 2007. The study area covered a portion of the Loop 202 freeway west of Mesa Drive to a retention basin east of Lindsay Road in Mesa, Arizona. Storm water samples were collected from two storm water detention basins and a discharge point to the Salt River. The study was conducted by manually collecting storm water samples with passive automatic samplers and analyzing them for various roadway constituents. A primary objective of this research effort was to establish baseline values of constituents in ADOT highway runoff, aiding in the evaluation of related best management practices. A total of 16 storm water samples was collected from the research area between January 2007 and December 2007.

The Arizona Statewide Transportation Improvement Program identifies statewide priorities for transportation projects. It is a compilation of projects utilizing various federal funding programs and includes highway projects on the cities, counties, and state highway systems, as well as projects in the National Parks, US Forest Service, and Indian Reservation Roads. This is a four-year project list compiled in cooperation with the Federal Highway Administration, Federal Transit Administration, Council of Governments, and the Metropolitan Planning Organizations. Projects are selected for inclusion in the STIP based on adopted procedures and criteria.

Transportation is critical to Arizona’s economic success. To have a strong economy, our state must have quality highways, public transit, railroads, airports and ports of entry to get people to work and to move products and provide services. By building transportation infrastructure, we can actually strengthen the economy, create jobs and support business development. However, a significant gap exists between projected revenues and transportation investments necessary to support a vibrant economy. Our priorities for the future will focus our limited resources on preserving and modernizing what we already have to protect the taxpayer investment in the existing transportation system.

The Department was established by the state legislature in July 1974 by combining the former Arizona Highway Department (originally established in 1927) and the Department of Aeronautics (originally established in 1962). The Department is not legally separate from the State of Arizona's primary government. The Department's mission is to provide a safe, efficient, cost-effective transportation system. The vision is the standard of excellence for transportation systems and services. This report includes all funds used to record the financial activity of the Department.
