Results of Archaeological Phase 1 Data Recovery at AZ AA:12:97 (ASM) for a Tucson Electric Power Substation, Tucson, Pima County, Arizona (TR2005-21) (PDF)
The project area is located in Pima County, in the southwest quarter of Section 17, Township 13 South, Range 13 East (Figure 1.1). Specifically, the project area is located within and adjacent to the existing TEP powerline easement on City of Tucson property, northeast of the Silverbell Road and El Camino del Cerro intersection. TEP plans call for installation of buried electric lines and a new powerline pole, and construction of a substation. The substation will be located near the northern boundary of the city-owned parcel, just east of the existing TEP powerline. One trench for buried electric lines will run from El Camino del Cerro to the southwestern corner of the substation. Another trench will run from the northeastern corner of the substation due west to Silverbell Road. The new power pole will be located within the TEP right-of-way easement just west of the proposed substation; electric lines will lead from this pole into the substation.
