On behalf of the City of Ingram, Texas, SWCA Environmental Consultants (SWCA) conducted an intensive cultural resources survey of the proposed Brushy Creek Sewer Line Project (Project) in Kerr County, Texas. The approximately 1-mile-long sewer main extension line is being developed by the City of Ingram, a political subdivision of the State of Texas; therefore, the Project requires compliance with the Antiquities Code of Texas (ACT). In addition, the Project will receive federal funds from the U.S. Department of Agriculture (USDA); therefore, the work was conducted to comply with requirements of Section 106 of the National Historic Preservation Act (NHPA). This cultural resources investigation was conducted under ACT Permit No. 9243.

The Project begins just south of Winona Street West and terminates just south of Highway 27. The Project Area includes the proposed linear alignment situated within a 25-foot-wide corridor and lies on undeveloped land. Proposed impacts are expected to include widespread surficial modifications with deeper impacts in location of sewer lines.

The cultural resources investigation consisted of a background and historical map review, followed by intensive pedestrian survey augmented by shovel testing conducted by SWCA archaeologists. SWCA’s background review determined that there are no known cultural resources within the Project area. SWCA also reviewed a 0.5-mile study area surrounding the proposed Project. This review determined there are a total of five previously conducted surveys and six previously recorded archaeological sites within 0.5 mile of the Project area. None of the six previously recorded sites have been recommended as eligible for listing on the National Register of Historic Places (NRHP). Additionally, no NRHP districts or properties, sites designated as State Antiquities Landmarks, historical markers, cemeteries, or local neighborhood surveys were identified within the Project area or the larger study area.

During field investigations conducted on February 4, 2019, SWCA conducted an intensive archaeological pedestrian survey augmented with shovel testing of the Project area. For linear projects, the Texas Historical Commission (THC)/Council of Texas Archaeologists (CTA) survey standards require a minimum of 16 shovel tests per mile with thorough documentation of all exceptions noted (e.g., disturbance, slope, and impervious surfaces). Based on these standards, SWCA exceeded the requirements by excavating a total of 34 shovel tests within the 1-mile Project area. No cultural materials were identified on the ground surface or within any of the shovel tests excavated within the Project area.

In accordance with the ACT and with Section 106 of the NHPA (36 Code of Federal Regulations [CFR] 800.4 (b)(1)), SWCA has made a reasonable and good faith effort to identify historic properties within the area of potential effects. SWCA recommends a finding of No Historic Properties Affected per 36 CFR 800. 5(b) and no further archaeological investigation of the current Project area is recommended. No artifacts or samples were collected during this survey. All survey-related documentation will be curated at the Center for Archaeological Research, University of Texas at San Antonio.
