Highway 274 Force Main Replacement



York County, SC


GTA provided geotechnical engineering and natural resource services for the replacement and expansion of approximately 7.0 miles of force main. GTA performed Standard Penetration Test borings along the length of the proposed force main to characterize subsurface conditions. GTA performed a wetland delineation of the proposed and alternative alignments, and obtained Nationwide Permit 12 verification from the U.S. Army Corps of Engineers for impacts to wetlands and waterbodies. GTA also obtained authorization from the South Carolina Department of Health and Environmental Control to install the utility line beneath state navigable waters (Lake Wylie). GTA managed botanical surveys to obtain project concurrence from the U.S. Fish and Wildlife Service.
