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.

Report is a review and compilation of existing data on water quality requirements of eight aquatic species. By identifying the water quality requirements of priority vulnerable species of concern, and assessing the quality of water that serves or might serve as potential habitat, we begin to understand which sources will support priority aquatic species identified by the SDCP.

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.
