This study from the citizens of the Arivaca community proposes to establish an Arivaca Resource Management Zone, where a atwo level management plan integrates the otherwise fragmented land use and water policies of the various regulatory agencies. The Arivaca watershed contains one of the last remaining cienegas and perennial streams in southern Arizona. These unusual water features exist because the area is still in a state of balance, where annual water consumption is less than the natural recharge replenishing the aquifer during years of average precipitation.
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.
Exotic species and their effect on Pima County's aquatic environments have become a priority issue for those involved with managing aquatic ecosystems in eastern Pima County. Invasion of exotic aquatic species presents a major challenge when preserving and restoring native aquatic species in the region.
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.
Report is a review and compilation of existing data on water quality requirements of eight aquatic species. By identifying the water quality requirements of priority vulnerable species of concern, and assessing the quality of water that serves or might serve as potential habitat, we begin to understand which sources will support priority aquatic species identified by the SDCP.
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.
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 study by DR. Philip Rosen stands as one of the most impressive, given the scope of the author's knowledge, and it is one of the most ingenious, given the proposed concepts for restoration and protection of native fish and frogs within the urban Tucson Basin.
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.
