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.
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.
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.
