A Cultural Resources Survey of 72.4 Miles (1,755 Acres) within the Tonto National Forest for the Salt River Project Coronado to Silverking 500-kV Transmission Line in Gila and Pinal Counties, Arizona

SRP requested that Logan Simpson conduct an intensive cultural resources survey of a 72.4-mile-long and 200-ft-wide (1,755-acre) segment of the SRP Coronado to Silverking 500-kV transmission line within the TNF and private land. This survey was requested for general inventory purposes and also in advance of proposed vegetation-maintenance activities within the project corridor. In addition, SRP may conduct maintenance or construction projects within the limits of the project corridor. Vegetation maintenance will be performed with mechanical mowing equipment, mounted on a track hoe or a rubber-tired frontend loader, and by hand-cutting using chain saws. All vegetation removal activities will be confined to the 200-ft-wide corridor with the exception of possible hazard tree removal, which would be accomplished using hand-cutting with chain saws only. Any disturbances that cannot be confined to the project corridor would be covered by a separate cultural resources survey once such areas are identified.
