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 objective of this Technical Data Notebook is to provide 100-yr peak discharges at a Concentration Point for the Unnamed 02 and 03 Washes, 100-yr floodplain boundary and erosion hazard information, using the most up-to-date topographic, hydrologic, and hydraulic data. This is a local study and has not been submitted to FEMA.

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.
