The city of Phoenix Planning Department was asked to prepare a land use plan to identify goals and policies to guide development decisions for an area beyond the banks of the Salt River and to complement the Phoenix Rio Salado Habitat Restoration Project (Rio Salado Project). In response, the Planning Department initiated a five-phase planning process to develop an area plan. The resulting plan builds on the community's vision of how the area will develop in the future and identifies the steps needed to make that vision a reality.

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.

Concern has been expressed that mesquite bosques are disappearing or diminishing in quality, and that the survival of the mesquite mouse is consequently threatened. This study, funded by a grant from the Arizona Heritage Fund to the Pima County Regional Flood Control District, investigated the current distribution of the mesquite mouse by reviewing historical records from museum specimens, examining existing potential habitat at historic locations of the species and elsewhere in the county, and conducting a live-trapping study at 19 sites representing a range of ecological communities with mesquite as a major component.
