Results of Archaeological Testing, Research Design and Data Recovery Plan at Site AZ AA:12:111 (ASM) for Part of Phase I Expansion at The Ina Road Water Pollution Control Facility, Pima County, Arizona

Summary

This testing report and data recovery plan has been assembled to address issues specific to the construction of a pipeline and headworks associated with the Phase I expansion of Pima County’s Ina Road Wastewater Pollution Control Facility (treatment plant). It comprises three chapters sections, the first of which presents a project introduction and overview. The second chapter summarizes the results of the testing project and includes a discussion of eligibility of the archaeological properties for nomination to the National Register of Historic Places. Chapter 3 presents the research design and a plan of work for data recovery at the project site.

Between August 13 and September 4, 1998, archaeologists from SWCA, Inc., Environmental Consultants (SWCA) tested a portion of site AZ AA:12:111 (ASM), for part of the planned Phase I expansion of the Ina Road Water Pollution Control Facility (WPCF) in Tucson. The testing was designed to identify and evaluate buried cultural deposits that will be affected by the construction of two structures involved in the WPCF expansion: Structure 14A, a pipeline, and Structure 14, a headworks building. The information gained from these test excavations guides the planning of data recovery actions on this portion of the site.

In a unusual scenario, Desert Archaeology, Inc. (DAI) was conducting intensive data recovery excavations at the same site during our testing project. Their work focused on what is called the On-Ramp Locus of site AZ AA:12:111 (ASM), located within an Arizona Department of Transportation (ADOT) right-of-way just east of the Interstate 10 frontage road (Mabry 1998a). One goal of our investigations, following the plan outlined in Wellman (1998), was to determine the nature and horizontal extent of the site west of the frontage road, to compare with and complement the data produced by DATs ongoing excavations in the ADOT right-of way. We found that very similar stratigraphic units extend from the On-Ramp Locus across our project area, together with deeply buried cultural deposits and features. Some of these deposits have previously been dated to the Late Archaic-Early Agricultural period, particularly the San Pedro Phase of the Late Archaic, and one may be associated with the Middle Archaic (Wellman 1998:3; Mabry 1998a, 1998b).
