Groundwater resources of the Prescott AMA continue to be depleted on a regional basis, resulting in decreased groundwater storage in the aquifers of the area. In addition, natural groundwater discharge from the area has decreased with potential impacts on riparian areas and downstream users.
Includes the information needed to draft the Water Resources Element and also describes the options that Pima County has to deal with water supply issues in light of the need to protect riparian and wetland areas under the SDCP.
Includes the Pima County staff response to Tucson Water Comments (May 16, 2001) and An Evaluation of Hydrologic and Riparian Resources in Saguaro National Park (March 2001). Groundwater withdrawals pose a threat to middle basin riparian areas.
The purpose of this report is to summarize information relevant to water aspects of the SDCP and the Pima County Comprehensive Plan. It deals with water supply and human water demand, and water supplies and needs for riparian and wetland habitat.
The objective of this Technical Data Notebook is to provide 100-yr peak discharges at a Concentration Point for the Unnamed 02 and 03 Washes, 100-yr floodplain boundary and erosion hazard information, using the most up-to-date topographic, hydrologic, and hydraulic data. This is a local study and has not been submitted to FEMA.
Describes a comprehensive regional policy direction to achieve meaningful riparian restoration necessary for endangered species compliance and the basic relation of water policy to conservation planning.
This memorandum describes (1) the potential applicability to Pima County of a national initiative to institute reforms in floodplain management; and (2) an assessment of the effectiveness of Pima County's Riparian Habitat Mitigation Ordinance (attachment). An inter-departmental team was formed to formulate specific proposals for consideration as part of the Riparian Protection Element of the SDCP and the major plan amendment to the County's comprehensive plan.
Concerns research into the origin of water sustaining the Bingham Cienega. For purposes of long term management, we need to understand what the source of water is for the various riparian areas.
Elements of the comprehensive plan now include planning for water resources that must address the currently available surface water, groundwater, and effluent supplies and provide an analysis of how the future growth projected in the county plan will be adequately served by the legally and physically available water supply. This is the first study to be issued as part of the Water Resources Element and identifies a number of measures that can be taken to conserve water, including measures that can be taken by Pima County in the form of ordinance adoption.
