The result of an application to the Arizona Department of Transportation Planning Assistance for Rural Areas (PARA) Program to conduct a multimodal transportation study to address transportation issues in the community. The purpose of the study is to identify the most critical multimodal transportation infrastructure and service needs within the Picture Rocks study area and recommend a program of short-range (0-5 years), mid-range (6-10 years), and long-range (11-20 years) improvements.

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.

Flooding and erosion within the Ranch Estates subdivision during the 2007 summer monsoon season raised the concerns of homeowners. This study addresses the impact of recent improvements in the drainage area upstream; provides updated flood-hazard mapping for the area, and identifies mitigation measures that could be implemented by the affected homeowners to address their flood/erosion hazards.
