Phase I Data Recovery at Eight Sites along the Estrella-Stockham Segment of the Union Pacific Railroad in Pima, Pinal, and Maricopa Counties, Arizona

Summary

The Union Pacific Railroad (UPRR) has planned a major construction effort within its 200-foot-wide right-of-way (ROW) throughout much of Arizona. The UPRR Sunset Accelerated Capacity Project includes construction of a second rail line running from Tucson (in Pima County) to Yuma (in Yuma County), as well as renovations to the existing line, such as construction of new bridges and culverts. A Section 404 permit requires that the U.S. Army Corps of Engineers (USACE) consider the cultural resources of the area under Section 106 of the National Historic Preservation Act. In November and December 2006, SWCA Environmental Consultants (SWCA) conducted an archaeological survey of 159 designated washes that potentially fall under the jurisdiction of the USACE within the UPRR ROW in Pima, Pinal, and Maricopa counties, Arizona (West and Ezzo 2007).

Ten sites and 76 historical bridges and culverts were recorded. The bridges and culverts were considered to be potentially contributing elements to AZ Z:2:40 (ASM), the Southern Pacific Railroad (SPRR), which was one of the 10 sites recorded during survey. These structures have been mitigated through Historic American Engineering Record documentation (Steely and Levstik 2007). One other archaeological site is a linear feature—AZ AA:2:118 (ASM), State Route 84/Casa Grande Highway—and will not be impacted by the UPRR undertaking.

The remaining eight sites will be impacted by the project and that mitigation will be required. Impacts include construction of the new rail line and renovations to the existing line, as well as construction of temporary staging areas for materials and machinery. Five of the sites have been recorded previously, and four have been determined eligible for inclusion in the National Register of Historic Places (NRHP) by the Arizona State Historic Preservation Office (SHPO); SHPO has determined that the fifth site, AZ AA:12:858 (ASM), requires testing to determine its eligibility. The three newly recorded sites were recommended eligible by SWCA; SWCA’s recommendations were accepted by SHPO (West and Ezzo 2007).
