DRAPER, UTAH (AP) — Two dangerously unstable homes in suburban Salt Lake City whose occupants were ordered to evacuate six months ago have collapsed down a hill. No one was injured when the unoccupied houses broke apart early Saturday in Draper. Officials say the homes had been in danger due to sliding that resulted from shifting ground and breaks in the foundations. Two other nearby residences were evacuated for safety reasons afterward. Officials said they followed up with the developer, Edge Homes, for months on engineering studies of the stability of the area. Edge Homes did not immediately respond to messages seeking comment.
