A Class I Inventory of 9.61 Miles for the Thunderstone to Verde 69 kV Rebuild, Maricopa County, Arizona

Author(s): Teresa L. Rodrigues; Mary-Ellen Walsh

Year: 2001


On December 15, 2000, Entranco was authorized by Salt River Project (SRP) to conduct a Class I Inventory of an approximately 9.61-mile-long, variable width corridor from the Thunderstone Receiving Station to the Verde Substation in Maricopa County, Arizona. The project area includes Bureau of Indian Affairs right-of-way across the Salt River Pima-Maricopa Indian Community, and land under the jurisdiction of the Bureau of Reclamation, operated and managed by the Central Arizona Project and SRP.

This research is undertaken as part of the proposed SRP Thunderstone to Verde 69 kV Rebuild project. The purpose of the Class I Inventory is to identify all previously recorded cultural resources and cultural resource projects that have occurred within the project area and its immediate vicinity. Cultural resources within these areas could be subject to direct or indirect adverse effects from activities associated with the SRP Thunderstone to Verde 69 kV Rebuild project. For purposes of this study, cultural resources are prehistoric or historic archaeological sites or objects, and potentially significant historic buildings or structures. An evaluation of Traditional Cultural Properties was not included in this inventory.

The SRP scope of work includes the installation of a new conductor for the existing 69 kV line, removing and replacing overhead static wires, and the replacement of any poles necessary to accommodate the installation of a new conductor and overhead ground wires. All project work will be conducted within the existing SRP right-of-way, which varies in width from 30 feet (ft.) to 70 ft.

The content and level of detail appropriate for this Class I Inventory report was discussed with Mr. Richard Anduze of SRP prior to report preparation. Because the primary objective is to facilitate planning for a 69 kV upgrade of an existing line, it was agreed that the best approach would be to inventory existing data sources and report the locations of previously identified sites and surveys in relation to the project corridor. This method provides the essential information concisely and expeditiously, but does not include a broad overview of the environmental or cultural setting, or any synthesis of the cultural resource data into research-oriented conclusions. Thus, the report is considered only a partial Class I inventory, but it includes all information necessary for the immediate planning-related purposes. Because the project extends across federal land, this report was written to conform to federal guidelines.

This is a revised report.
