One of Cincinnati's newest parks is slipping into the Ohio River. City officials want answers from an engineering firm that was hired to do the site survey study. Cincinnati dedicated the Theodore Berry International Friendship Park in 2003. Within four months, geological readings taken 16 days apart found that the earth beneath the park had slipped one-eighth of an inch toward the river. Cincinnati has spent one-point-five million dollars in emergency repairs on the park, which cost almost nine million dollars. The city wants an explanation from HC Nutting, the engineering company that told the city in 1998 that the riverbank was stable. The firm's president says he is working with the city to find solutions. Jack Scott said it is difficult to predict earth movements.
