Final Report of Monitoring for the Southwest Gas 2" Steel Main Replacement Project, Phoenix, Maricopa County, Arizona

Summary

Monitoring for the Southwest Gas 2" Steel Main Replacement Project identified two features within AZ T:12:37(ASM)-Casa Buena, and three canal exposures representing two canals (designated at AZ T:12:416 and T:417[ASM]). All feature recording protocols followed those methods set forth in the approved City of Phoenix blanket work plan (Montero and Stubing 2004). ACS’ monitoring for the Southwest Gas 2" Steel Main Replacement Project resulted in the monitoring of 98 new excavations, and the inspection of 52 previous excavations located within the site boundaries and buffer of AZ T:12:37(ASM)-Casa Buena, AZ T:12:256(ASM)-Grand Canal Ruins, and four previously unverified Hohokam canal alignments. The monitoring took place between February 7- April 4, 2012. In total, 41 discontinuous person-days were expended in the field. The fieldwork was conducted under the authority of project-specific permit 2012-065ps and Burial Agreement Case No. 2012-009 issued by ASM.

Three canal exposures representing two canals, one compound wall fragment, and one horno were identified by the project. AZ T:12:416(ASM) consists of the two canal exposures representing a previously unplotted Hohokam lateral canal. AZ T:12:417(ASM) consists of a single canal exposure representing a projected Hohokam distribution or main canal. Both of these canals are part of Canal System 2. The results of pollen returned from T:12:417 indicates the presence of maize fields in proximity to the canal; the presence of red ware ceramics in the canal matrix suggests use during the Classic period. The horno and compound wall fragment were both identified during monitoring at T:12:37(ASM)-Casa Buena at the southern portion of the project area. The location of the compound wall indicates that a previously uninvestigated Classic period habitation area. No cultural materials were identified by the monitoring at AZ T:12:256(ASM)-Grand Canal Ruins.
