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.

Ranching is a significant land use that has served to protect our natural open space, and it continues to be an important traditional industry that has shaped the rural landscape.
