Between February 17-21, 2015, personnel from POWER Engineers performed an intensive archeological survey of a proposed electrical substation, substation access road, and transmission line on state-owned Port of Brownsville property in Cameron County, Texas. The investigation was undertaken under Texas Antiquities Permit 7176. The approximately 29-acre proposed substation project area is located approximately 1.3 miles north-northwest of the intersection of Chemical Road and the Brownsville-Port Isabel Highway (State Highway 48). The proposed transmission line begins approximately 0.39 north of the intersection of U.S. Highway 281 and County Road 2556 and extends for 46.8 miles to the Palmito Substation. Approximately 3.4 miles of the proposed transmission line is on the Port of Brownsville property, with a proposed 150-foot-wide right of way. Additionally, 3,680 feet of proposed new permanent access roads are proposed extending south from the substation. One archeological site, 41CF143, is recorded adjacent to the proposed transmission line. The site was not observed on the surface or in shovel tests within the proposed right of way. No cultural resources were recorded during the survey. Due to the lack of cultural materials in the Project area, POWER recommends that construction activities within the Project area be allowed to proceed without further consultation. If, during construction of the substation, transmission line, or access road, cultural resources are encountered, all activities at the location should be halted until the THC is notified and an appropriate course of action is determined.
