The San Xavier District of the Tohono O’odham Nation is home to approximately 2,000 people. Numerous others come to the District to visit the San Xavier del Bac Mission Church. The San Xavier District Pedestrian Access and Safety Study is being prepared to improve the walking and bicycling environment on the San Xavier District for Community members and visitors alike. The study is being funded by the Arizona Department of Transportation Multimodal Planning Division’s Planning Assistance for Rural Areas program.

This report and the accompanying Geographic Information System (GIS) datasets summarize the results of the workshop held in Florence, Arizona in 2010. At this workshop, stakeholders representing a broad range of organizations and interests identified and mapped the locations of important wildlife linkages across Pinal County. This report provides background information on the importance and benefits of conserving wildlife linkages for both people and wildlife in Pinal County and describes the methods used during stakeholder workshops and in developing the accompanying GIS products. It includes a series of maps generated from the digitized stakeholder data that depict the general locations of wildlife linkages and potential barriers to wildlife movement within Pinal County. The maps are followed by tables with descriptive information about the habitat areas each linkage connects, the species each linkage serves, and known threats and potential conservation opportunities associated with each linkage.

Following the completion of the 2005 report, an Act was passed that contained a number of important new and continued funding sources for safety related projects, programs, and initiatives. This required every state to develop a Strategic Highway Safety Plan. This 2007 report represents Phase 1, Development Plan and is a comprehensive, collaborative, high level, statewide safety strategy that will guide Arizona's safety change initiative. The Arizona Department of Transportation was assigned the role of project manager for this SHSP phase by the Governor's Traffic Safety Advisory Council.

The historical advantages of Grand Avenue and the railroad that led to the development of the West Valley cities have become a detriment to the further development or redevelopment in the past few decades. There is general agreement that significant improvements are needed for the Grand Avenue Corridor. Identified transportation funds provide an opportunity to develop a more modern transportation corridor along Grand Avenue. This study addresses these concerns by developing, evaluating, and recommending transportation investment options.

One goal of the SDCP was to obtain a permit from the U.S. Fish and Wildlife Service under Section 10 of the Endangered Species Act to enable incidental take of species protected by the ESA in the course of development in Pima County. This report provides the county with the framework to go forward and further its analysis of the final funding costs for a Section 10 Permit.

Provides basic information about the source of surface water in Cienega Creek at the downstream end of the natural preserve, which will contribute to efforts to conceptualize and implement effective land management proposals for the SDCP. Study results indicate that the surface flow or subflow from Agua Verde Creek do not significantly influence the water in the Cienega Creek.

Conducted for the Pima County Flood Control District by the Pima Association of Governments in order to determine if stormflows on the Cienega Creek have changed over time when analyzed in terms of frequency, volume, and seasonallity. In a data search that extends back to the 1950s, they were able to determine the daily mean flow, the flows over base, and the annual peak flows of the Cienega Creek.

The purpose of this project was to compile information on groundwater withdrawals and surface water diversions near perennial streams, intermittent streams, and shallow groundwater areas previously identified by PAG for the SDCP. The information could be used to prioritize future investigations of potential impacts of these withdrawals and diversions on riparian and aquatic habitats for the SDCP.

This document and the Geographic Information System file that is now a part of the County library of over 1000 coverages, gives the scientific community access to mapping that better differentiates perennial, ephemeral and intermittent watercourses, and provides more comprehensive coverage of shallow groundwater sources. This data is significant because riparian habitat is one of the most important and least protected of the habitat types in Pima County.
