Salt River Project (SRP) requested that Logan Simpson Design Inc. (LSD) perform a Class III cultural resources survey of the approximately 4.25-mile by 20-m-wide corridor to identify and evaluate any cultural resources that could be affected by the construction of a new 69kV transmission line from the existing Quail Substation to the proposed Shipley Substation between Quail Run Road and Cooper Road in Magma, Pinal County. The survey area measures 22,440 ft long by 65.62 ft wide and encompasses 25.85 acres of private land and 7.95 acres of State Trust land under the jurisdiction of the Arizona State Land Department, totaling 33.80 acres. The Bureau of Reclamation (Reclamation) right-of-way within the project area was not surveyed as part of this project. It had previously been surveyed and is highly disturbed; no sites are reported in the Reclamation right-of-way where it crosses the SRP project area. Although the SRP project corridor is only 36 feet wide, a 20-m-wide corridor was surveyed. The proposed project consists of constructing a new 69kV transmission line, including installation of utility poles. The Class III survey was undertaken at the request of SRP as due-diligence as part of the planning for the installation of the line, and because portions of the project are located on ASLD land, the cultural resources survey was completed in compliance with the requirements set forth in ARS § 41-861 et. Seq., the Arizona State Historic Preservation Act.
