Nearly two weeks after flooding damaged parts of De Pere High School, the school district is providing new details about the extent of the damage and the repairs now underway.District officials say 51 rooms and spaces were affec ted when flooding struck the school on July 8, including the library media center, nearby classrooms, band rooms and athletic training areas.The district told NBC 26 the initial cleanup and mitigation work has been completed. All affected areas have reopened except the library, which remains closed.Officials say an investigation found failed drain pipes beneath the building caused the flooding.
