Pima County's Cienega Creek Natural Preserve surface water and groundwater monitoring project. This report summaries PAG's groundwater and surface water monitoring between July and June each fiscal/ monitoring year. The report contains monitoring methodology, comprehensive maps, and graphs of trends for surface flow volume, wet-dry flow lengths, groundwater levels and water chemistry. It also contains information on drought, erosion and repeat photography.

The purpose of this report is to present the data gathered to date in the Santa Cruz AMA in support of the management goal and groundwater modeling effort. This report presents groundwater and surface water monitoring data, USGS stream gaging data, effluent data, gravity studies, historical water use and water quality data for three distinctive stream reaches of the Santa Cruz River.

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.

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.

Wilson & Company recently completed the City of Casa Grande Small Area Transportation Study. The SATS notes that “as the City of Casa Grande increases in size and planning area, the roadway network is also growing to meet the additional travel demands significant improvement measures are needed to meet the travel demand generated by forecast population and employment growth”. Given the findings of the SATS, the City of Casa Grande contracted with TischlerBise to calculate an infrastructure improvement plans and updated development fees for transportation.

The City of Casa Grande engaged TischlerBise to update its Infrastructure Improvements Plans and development fees for several categories of necessary public services. TischlerBise previously calculated development fees for the City in 1999, 2003, 2006, and 2008. Municipalities in Arizona may assess development fees to offset infrastructure costs to a municipality associated with providing necessary public services to a development. The development fees must be based on an Infrastructure Improvements Plan. Development fees cannot be used for, among other things: projects not included in the Infrastructure Improvements Plan, projects related to existing development, or costs related to operations and maintenance.

This report summarizes published reports and public datasets pertaining to the subsurface hydrology of Sopori Basin. It includes descriptions of the hydrogeology of the basin, recharge, the number and type of wells, well installation frequency, changes in water levels through time, shallow groundwater areas, groundwater pumping, grandfathered irrigation rights and water quality. Data sources and limitations also are discussed. This report is intended to provide a broad understanding of the groundwater conditions in Sopori Basin based on existing information.

Pima Association of Governments updated a portion of the Water Usage Along Selected Streams in Pima County, Arizona, which PAG created in 2000. The updated report and datasets show current potential water usage in these critical areas. Deliverables include the shapefiles, spreadsheets and maps that accompany this memorandum. The purpose of this report is to provide updated information about the location and pumping history of wells located in Pima County near shallow groundwater areas, generally located near drainages.

Pima County’s Southwest area has been identified by County planners as a potential and strategic growth area. To accommodate population growth, the existing infrastructure must be improved and expanded. The purpose of this Infrastructure Plan is to provide a basis for infrastructure decision-making related to development in the Southwest area. It quantifies the nature, phasing, financial impacts, and funding possibilities for those flood control, parks and recreation, transportation, wastewater infrastructure and other improvements that are necessary to service future saturation growth within the study limits.
