Cultural Resource Analysts, Inc., personnel completed a records review and cultural resource survey for the proposed expansion of the existing Six Mile Boat Ramp in Sabine County, Texas. This work was performed to assist the Sabine River Authority of Texas in complying with Section 106 of the National Historic Preservation Act of 1966 (Public Law 89-665, 16 U.S.C. 470h-2) as an applicant for a Section 404 Clean Water Act Permit from the US Army Corps of Engineers, and the provisions of the Texas Administrative Code regarding archaeological resources on public lands. The Texas Administrative Code requires review of projects on state-owned lands by the Texas Antiquities Commission. The Sabine River Authority of Texas is considered a political subdivision of the State of Texas, and therefore it has a responsibility to provide the Texas Antiquities Commission an opportunity to review projects that may affect potential or designated archaeological sites. This project was performed under Texas Antiquities Permit (No. 9155). All work was performed pursuant to the guidelines published by the Council of Texas Archeologists and adopted by the Texas Historical Commission, and this report was prepared following the short report format in the Guidelines for Cultural Resource Management Reports published by the Council of Texas Archeologists. The current proposed project includes the expansion of the Six Mile Boat Ramp on the Toledo Bend Reservoir in Sabine County, Texas. The proposed development includes the addition of a handicap-accessible floating boat ramp, the clearing of approximately 0.4 ha (1.0 acre) of trees, the construction of a parking area, the addition of a vault toilet, the addition of two tables on concrete platforms, and the clearing of trees along the shoreline to provide an enhanced scenic view. In order to provide some flexibility in siting these facilities, the direct and visual areas of potential effect for this project were within a polygon adhering on its southern and western boundaries to the property line, and roughly buffered to the north and east by the existing shoreline of the Toledo Bend Reservoir. It is estimated that the area of potential effect for this project measures 1.2 ha (3.0 acres), of which approximately 0.9 ha (2.2 acres) could be surveyed, excluding paved surfaces. The records review for this project was conducted on October 18, 2019, prior to the commencement of the field survey, to identify cultural resources or cultural resource investigations previously documented within the area. This file search utilized online files maintained by the Texas Archaeological Research Laboratory at the University of Texas. Additionally, historic maps were examined to identify the locations of any potential historic archaeological sites. The records review indicated that one previously documented site, 41SB58, was located within approximately 50 m (164 ft) to the north of the proposed project area. Additionally, one historic structure was depicted within the project area on historic mapping. Fieldwork was conducted on November 19, 2019, and was completed in 11.5 person hours. The project area was systematically investigated by pedestrian survey and screened shovel tests spaced at a 30 m (98 ft) interval on pedestrian transects spaced at 30 m. The fieldwork for this project resulted in one newly recorded isolated find that is not eligible for designation as a Texas State Archeological Landmark or for listing in the National Register of Historic Places. Based on the findings of this work, it is recommended that the project area be considered cleared from a cultural resource perspective.
