SIOUX CITY, Iowa (AP) — A consultant says the landmark Woodbury County Courthouse needs $12 million in exterior repairs. The county supervisors said Tuesday after hearing a report from consultant Pete Franks that they’ll decide at a future meeting when to start the repairs and how to pay for them. The exterior has deteriorated so much that officials have been able to pull entire bricks from the foundation in some places. County officials last year had estimated the repair price tag at $2.1 million.

The courthouse — considered the largest publicly owned Prairie School-design building in the world — was put on the National Register of Historic Places in 1973 and was designated a National Historic Landmark in 1996. The supervisors are planning 100th anniversary activities for the building next spring.
