With that awareness, Patrick said, the college commissioned a study to validate that history and conduct ground penetrating radar to look for burials. Radar scans last year were inconclusive on whether human remains are under a parking lot at 106 Coming St., the former headquarters for the YWCA of Greater Charleston, he said. “We aren’t saying there aren’t human remains,” Patrick explained. The coalition has asked the S.C. Department of Environmental Services (SCDES) to hold a separate public hearing on the college’s request to demolish the YWCA building, Brown said. “But none of that (piling) will be done until we have gone through the process to ensure that there are no human remains or if human remains are discovered then all of those human remains” can be reinterred at the site or elsewhere, he said.
