On behalf of Oden Hughes, Pape-Dawson conducted an intensive archaeological survey of the proposed NWC Bulverde/1604 Sewer Extension Project in San Antonio, Bexar County, Texas. The project proposed to begin on the southwest side of Classen Road approximately 0.2 kilometers (km) (0.13 mile [mi]) east of its northern intersection with Bulverde Road. The proposed line would parallel Elm Waterhole Creek to the west and south approximately 0.8 km (0.5 mi). At this point, the line would cross Autry Pond Road in a southwestern direction eventually paralleling Bulverde Road to the intersection of Redland Road for a total length of approximately 0.4 km (0.25 mi). This project would entail the installation of 1.2 km (0.75 mi) of new sewer line within a 5-meter (m) (16-foot [ft])-wide permanent easement and an adjacent 8-m (25-ft)-wide temporary easement along whichever side was available. The Area of Potential Effects (APE) for the proposed project was defined as a 30 m (100 ft) buffer centered on the proposed SAWS centerline totaling 3.7 hectares (ha) (9.18 acres). The depth of vertical impacts was not yet been determined, but utility installations typically require 1.8 to 2.4 m (6 to 8 ft). Notably, the sewer alignment was changed after completion of this archaeological survey and installation will no longer take place in this APE. The survey for the new alignment was completed under Texas Antiquities Permit #8870.

Although Oden Hughes would construct the new sewer line, San Antonio Water Systems (SAWS) would be the grantee of the easement after construction. For this reason, compliance with the Antiquities Code of Texas (ACT) was required. In addition, this project would require a Nationwide Permit from the U.S. Army Corps of Engineers (USACE). Thus, compliance with Section 106 of the National Historic Preservation Act (NHPA) (Title 36 Code of Federal Regulations Part 800.4 [36 CFR 800.4]) was required. In addition, the project was located within the San Antonio city limits, which necessitated compliance with the Historic Preservation and Urban Design Section of the City of San Antonio (COSA) Unified Development Code (UDC).

Pape-Dawson conducted the intensive archaeological survey on September 20, 2017. The entirety of the APE was subject to visual inspection supplemented by judgmentally placed shovel tests in order to evaluate the potential for buried cultural resources. This work was conducted under Antiquities Permit No. 8161 with Virginia Moore, M.A.G. serving as Principal Investigator. A total of 16 shovel tests was excavated within the APE, all of which were negative for archaeological material. During this survey, one previously recorded site (41BX1786) was revisited within the limits of the APE. However, no cultural deposits associated with the site were encountered. Given the absence of artifacts observed during the current survey, Pape-Dawson recommends that 41BX1786 is ineligible within ROW for State Antiquities Landmark (SAL) and National Register of Historic Places (NRHP) designation.

No archaeological resources were located or recorded during this survey. As no properties were identified that meet the criteria for listing in the National Register of Historic Places (NRHP) according to 36 CFR 60.4, or for designation as a State Antiquities Landmark (SAL) according to 13 Texas Administrative Code 26.12 (13 TAC 26.12), Pape-Dawson recommends that no further archaeological work is necessary for the proposed undertaking as presently designed. However, if undiscovered cultural material is encountered iii during construction, it is recommended that all work in the vicinity should cease and the THC and COSA archaeologists be contacted to ensure compliance with the NHPA, ACT, and UDC. No artifacts were collected, but all project records and photographs will be curated at the Center for Archaeological Research (CAR) at the University of Texas at San Antonio.
