A Cultural Resources Survey of 84.3 Acres of Tonto National Forest and Private Lands for the SRP Silver King to Goldfield 230kV Upgrade, North of Superior, Pinal County, Arizona

Author(s): David A. Bild

Year: 2008


SRP is planning to upgrade the current carrying capacity of 18.3 miles of the existing Silver King to Goldfield 230kV line. In order to accomplish this, SRP plans to “bundle” the existing 230kV conductors by adding a second conductor to each of the three existing single-conductor phases. To add the new conductors, SRP will need to re-open some original access roads, and the selected wire, puller, sleeving, and anchor sites used during the original 1978 line construction. The existing transmission line corridor has been previously surveyed for cultural resources (a corridor measuring 70 ft south and 220 ft north of the existing 230kV line and including the 500kV line) and was not re-surveyed for this project. LSD conducted a Class III cultural resource survey of a 50-ft-wide corridor centered on each of the access roads leading to the transmission line corridor. Some of these roads or small segments of these roads may need to be re-bladed or have fill added to allow equipment to approach the project area. Thirty-eight segments of access roads, as well as puller, wire, and anchor sites located outside the corridor were surveyed, totaling approximately 13.9 miles (84.3 acres). LSD also re-located previously recorded sites within the corridor in the vicinity of towers or access roads to verify site locations and boundaries. This report pertains to the portions of the project area on TNF and private land between the Silver King Substation and the TNF boundary. A separate report for portions of the project area on State Trust and private land west of the TNF boundary will be submitted to the Arizona State Land Department.

This report was revised in February 2009. The original report was dated April 2008.
