The State of the System Report is a compilation of the physical inventory and status of the Maricopa County Department of Transportation’s infrastructure. It addresses roadway congestion, traffic safety, low volume road paving, bridges, and pavement conditions. Also, included are recommendations for future improvements within each of the infrastructure categories. The SOS report has been produced annually since 1998.

Elements of the comprehensive plan now include planning for water resources that must address the currently available surface water, groundwater, and effluent supplies and provide an analysis of how the future growth projected in the county plan will be adequately served by the legally and physically available water supply. This is the first study to be issued as part of the Water Resources Element and identifies a number of measures that can be taken to conserve water, including measures that can be taken by Pima County in the form of ordinance adoption.
