The Cochise County Comprehensive Plan adopted in 1984 and last revised in 2011 serves to promote orderly and well-planned County growth. The Plan consists of a written document establishing land use, transportation, water conservation and public facility goals and polices and a series of maps that serve as a blueprint for the intensity and type of land uses expected near the incorporated cities and towns and in the outlying rural areas. Community and area plans are amendments to the Comprehensive Plan that address the future growth of a specific community or region of the County. They offer an opportunity for citizens who live and work in an area to have voice in the location, type and intensity of growth in their community. These plans based on long discussion with the community are designed to support land uses that enhance and protect an area’s unique character.

The Augusta Resources Corporation proposes to construct the Rosemont Mine project in the northern Santa Rita Mountains. This report is a reconnaissance analysis of the conceptual flow and water balance in the area. The conceptual flow model for the area is based on topography, geology and precipitation and identifies the likely flow paths in the watershed and aquifer system. The water balance includes estimates of recharge to and groundwater flow from the area; there is no evapotranspiration discharge from the regional groundwater.
