At the request of CPS Energy (CPS), Pape-Dawson Engineers (Pape-Dawson) conducted archaeological monitoring during the installation of a new gas mainline (ML) and eight individual service extension line replacements (LSETs) along Potomac Street in eastern San Antonio, Bexar County, Texas (Project). The Project consists of the addition and replacement of approximately 151 feet (ft; 46 meters [m]) of gas main within Potomac Street and its right-of-way, between the intersections of St. James Street and St. George Street (ROW) (Project Area). The Project is situated in an urban residential area bordering historic and modern structures to the north and south, as well as the Agudas Achim Cemetery, a Jewish cemetery included in the Old San Antonio City Cemeteries National Register of Historic Places District.

The Project is located within the San Antonio City Limits and requires compliance with the Historic Preservation and Design Section of the City’s Unified Development Code (UDC). The Project also impacted ROW owned by the City of San Antonio (COSA), requiring compliance with the Antiquities Code of Texas (ACT). As no federal permitting or funding is associated with the Project, compliance with Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended (36 Code of Federal Regulations [CFR] 800), is not required.

The proposed Project included the excavation of a backhoe trench to expose an existing east/westoriented gas mainline, an adjacent trench to install a new east/west-oriented replacement gas ML, and eight lateral LSETs (four to the north and four to the south, branching off from the new replacement gas mainline into eight of the adjacent houses). Depths of impact for the Project did not exceed 4 ft (1.2 m) below the ground surface.

Archaeological monitoring of the Project Area occurred between April 22 and May 5, 2020. Adam Leroy served as the Principal Investigator for the Project and was assisted by bioarchaeologist Mikayla Mathews. No significant cultural features or undisturbed cultural material deposits were encountered during the monitoring effort.

As no significant cultural resources were encountered during the Project, and provided that all gas line replacements associated with the Project occur within the monitored area, Pape-Dawson recommends no further work for the proposed Project as inventoried, mapped, photographed, and described herein. All records associated with this Project are curated at the University of Texas at San Antonio Center for Archaeological Research. Following analysis, artifacts will be returned to the landowners or discarded with landowner approval.
