Builds upon the "Biological Stress Assessment" through the identification of threats and stressors to watercourses within Pima County. It provides background on technical and water policy matters, describes potential and existing impacts to watercourses within Pima County, suggests options for reducing stressors, and outlines a number of issues for discussion withing each watershed planning unit.

The purpose of this paper is to consider alternative assured water supply approaches for Superstition Vistas and to describe potential methods of providing water service to the property. Because this paper represents a cursory analysis of the study area and available supplies, the results should only be used for scoping more detailed planning efforts. The first issue examined is whether sufficient water supplies exist regionally to support projected growth including Superstition Vistas. Additionally, estimated demands for the property are presented. Finally, there a number of issues that complicate the process of acquiring supplies for an area like Superstition Vistas. This paper summarizes some of those issues.
