In June 1993, a massive sinkhole developed in a surface parking lot of a hotel facility in Georgia. The hole was a result of the soil erosion associated with a failed, 4-meter diameter combined sewer tunnel. Two fatalities occurred with the collapse. The subsequent forensic study uncovered a series of contributing factors, including a disregard for site history during the planning stage of the development, misapplication of a safety net, and a misinterpretation of the signs of impending failure in both the preventative maintenance inspections conducted by the city and forensic studies conducted by consultants immediately prior to the collapse.
