The objectives of this report are to document the on-site and off-site hydrologic and hydraulic assessment of the site and its characteristics, quantifying existing conditions peak discharges, and define the limits of 100-year on-site floodplains.
This parcel has some houses already constructed, but most of the area is left undeveloped and can be classified as desert foothills. The objective of this report is to determine all of the flows generated by a 100-year storm in excess of 100 cfs and then map the flood-prone boundaries for the associated channels.
Tucson Water's Valley View Reservoir site and Flecha Caida Ranch Estates #9 has experienced numerous drainage-related problems,including inundation, erosion, and limited access during the rainy season. A portion of the reservoir site and approximately one-half of the subdivision are both located in the 100-year flood plain.
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.
This report is being submitted for the purpose of reducing the erosion setback limits. The information contained herein supports the claim that a safe reduction in the setback distance can occur.
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.
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.
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.
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.
