The Altar Valley Conservation Alliance is a collaborative conservation organization founded in 1995, and incorporated as a 501(c)3 not-for-profit organization. Just southwest of Tucson, Arizona, the Altar Valley comprises approximately 610,000 acres of Sonoran desert grassland, some of the most biologically rich and ecologically threatened biotic communities in the world. Private ranches work side by side with federal, state and local agencies to manage the valley, which is the largest unfragmented watershed in Pima County, outside of the Tohono O’odham Nation to the west. This collection is an archive of reports and other documents specific to Alliance activities.

This document presents several options for restoration projects along Brawley Wash in the Altar Valley. The main objective of the study was to develop alternatives to control erosion along the ephemeral waterway. Ultimately, project planners recommended the construction of a grade control structure complemented by new vegetative management practices.
