SRP plans to construct a new 69kV transmission line to connect the Humphrey and Turpen substations to provide additional energy to SRP customers and to meet anticipated future needs. The new transmission line will tie into Humphrey Substation, on Riggs Road just west of Lindsay Road, using the existing poles along Riggs Road. From Val Vista Drive, a new line will be constructed from Riggs Road continuing north to Appleby Road and then turn west to meet Turpen Substation at the northeast corner of Appleby Road and Lindsay Road. Fifty-five to 70 new poles will be installed along Val Vista Drive and Appleby Road. The poles will be constructed of Douglas fir trees or weathered steel, will be 65 to 75 feet tall, and will be spaced 250 to 350 feet apart. EcoPlan conducted a Class III survey of this project area on August 24, 2020, and recorded no cultural resources (Rainey 2020). A possible alternate route for the transmission line along 148th Street and Chandler Heights Road was later identified and would require all new poles as described above. SRP requested that EcoPlan survey the alternate alignment. This report details the results of that survey. SRP contracted EcoPlan to conduct a Class III intensive pedestrian cultural resource survey prior to construction of the new transmission line. The purpose of the survey reported here was to identify cultural resources within the project area, assess their eligibility for listing in the National Register of Historic Places (NRHP), and make a recommendation concerning the potential effect of the proposed undertaking on cultural resources listed in or eligible for listing in the NRHP. SRP plans to construct a new 69kV transmission line to connect the Humphrey and Turpen substations to provide additional energy to SRP customers and meet anticipated future needs. SRP contracted EcoPlan to conduct a Class III intensive pedestrian cultural resource survey of an alternative alignment in advance of the project. EcoPlan conducted the survey of the project area on November 5, 2020. No previously recorded cultural resources were identified during background research, and no cultural resources were located within the project area during the survey. No additional archaeological investigations are recommended. |
