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.

Pima County, in partnership with the National Park Service, has been an active participant in the development of a 70 mile segment of the trail. With the preparation of this Master Plan, Pima County has embarked on an active program to acquire the necessary rights-of-way and easements and to construct the Pima County segment of the national historic trail.

This study covers the time period after 1200 A.D. in terms of the domestic landscape, the agricultural landscape, and the social landscape as the residents of southern Arizona adjust to upheaval and change in environmental and social conditions. This memorandum summarizes the study about the Classic Period and provides a comparison of findings and theories about area residents from both before and after 1200 A.D., which is the approximate time frame of the collapse and restructuring of cultural landscapes.

Pima County is endowed with many mineral resources, not only copper mines, but also the important products such as sand, gravel, and limestone used everyday in supporting the infrastructure of our cities. It is essential that these mineral resources, and the lands where they occur, remain available for exploration and development. This report presents an assessment of the mineral resources of Pima County based on hard data derived from many experienced geologists working in the private sector and from publications of state and federal government agencies.

Afterschool youth-development programs (AYDs) have grown significantly during the past 15 years in Arizona and nationally. Many providers have moved beyond simply providing a safe haven to actively promoting young people’s development. However, there is still tremendous opportunity for growth. There is also a continuing need to enhance coordination and collaboration among programs in order to extend their resources and heighten their impact.

Morrison Institute worked with AzCASE and VSUW to construct a 55-question survey using Qualtrics on-line software. While the term “afterschool” was used, the survey was designed to measure all types of out-of-school programs, regardless of whether they operate before or after school, on weekends, or during school and summer breaks. Approximately 1,800 questionnaires were distributed to individual program sites in Maricopa and Pima counties via a list provided by AzCASE. Though the survey did not utilize a random sample, its 38 percent response rate (681 returns) suggests that its findings can help educators, youth-development professionals, policymakers and the business community understand the scope, characteristics and needs of afterschool services in Arizona’s two largest population centers.
