Archeological finds will delay University of Iowa flood recovery.

Contractors working on flood recovery in the University of Iowa Hubbard Park stumbled upon archeological items, including foundations of bricks and limestone walls from the 1850s this week, while excavating for chilled water lines. Contractors also found projectile points — or arrowheads — that date back to 3,000 B.C.E.

UI officials will work with state archeologists and historic-preservation officials to inventory the items. The UI must work with the office in order to keep its Federal Emergency Management Agency funds.

Rod Lehnertz, Facilities Management’s director of planning, design, and construction, said flood recovery will be held up between two and three weeks, depending on the weather. Colder weather will slow archeologists as they try to recover items underneath Hubbard Park. Lehnertz said that while it will have an effect on the flood-recovery costs, the estimates are not yet available.
