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.
Erosion Monitoring for the Proposed Sierrita Pipeline Project
Altar Valley Conservation Alliance
In this letter, Patricia King and Mary Miller of the Altar Valley Conservation Alliance communicate their concerns over the lack of specific watershed stability standards and monitoring protocol within the monitoring and reclamation plan presented by Kinder Morgan for the Sierrita Pipeline Project. To remedy this situation, they suggest incorporating aerial videography as a monitoring technique and encourage the development of clear restoration standards.
