This study will prepare an updated Tribal Long Range Transportation Plan and a strategic plan for improvements over five-, 10-, and 20-year periods, incorporating both roadway and multimodal needs. Some key focus areas of the Plan are road maintenance and safety programs, as well as improvement plans for bicycle, pedestrian, and transit systems. It also Identifies updates to the Tribal Transportation Inventory and functional classification systems will assist in expanding the level and types of funding available for transportation projects.

Provides insights on historical and current issues in transportation planning. The first section describes the last five decades of planning efforts, funding initiatives and the increasing use of the roadway system. The second section is a series of fact sheets and maps of each subregion that presents the extent of the roadways, traffic volumes on major streets, transit and bicycle facility availability, future planned improvements, issues within the subregion, an overlay of the draft biological reserve, and in the northwest, a further overlay of pygmy-owl habitat with a detailed analysis of bond projects.

Provides background information relevant to the Circulation Element of the draft Comprehensive Land Use Plan. It describes historic traffic volumes for roads within the various subregional planning areas of Pima County, and compare Pima County trends to national data in areas such as vehicle ownership, travel time, vehicle miles traveled, work trip modes of travel, registration, and vehicle costs.

In the early 1990s, a study of the Tanque Verde Creek by Dr. Julie Stromberg and others described the relationship between the depth to groundwater and the health of the mesquite woodland habitat in the area. This report revisits the Stromberg study to describe variations in groundwater levels since the report was completed early last decade. They identified around 3,000 acres of riparian vegetation in the Tanque Verde-Agua Caliente shallow groundwater zone.

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.
