A Cultural Resource Survey for the Rosemont Project Utility Corridor, Pima County, Arizona

The project area of potential effect (APE) for the Class III cultural resources survey encompasses 713 acres. This APE is designed to accommodate the co-location of two utilities—in this case a water pipeline and the power transmission line noted above—in a single corridor that is approximately 14 miles long. The width of the corridor varies along its length. For 10 miles the survey corridor is 500 feet wide where the utilities may be co-located; the survey corridor in the remaining approximate 4 miles is 150 feet wide for the pipeline only.
