The owners of the Nook planned to open a restaurant inside a community center building in 2018 when they discovered the sinkhole. While they're not planning to build the restaurant there anymore, they're still concerned about the safety of people coming into the building. Since the sinkhole was discovered, it's been filled with grout. But the Nook owners and their attorney say there was no engineering report to say that action fixed the hole. Atlanta water crews came in and dug out the widening hole, thinking a 100-year-old masonry sewer under the building caused the collapse. But the city determined the sewer didn’t cause the crater and crews filled it in, leaving the cause a mystery. The plaintiffs have alleged that the conservancy 'sought to cover up the void or made misrepresentations about the repair to the public'.
