MADISON, Wis. (AP) – Plumbers and cleanup crews are trying to repair a burst pipe that caused flooding in the state Department of Natural Resources’ headquarters in Madison. Stephanie Marquis is a spokeswoman for the state Department of Administration. She says the pipe burst Monday night, causing flooding on the building’s ground floor as well as on the first, second, third, fifth, sixth and seventh floors. She said she didn’t have a cost estimate of damage. DNR spokesman Bill Cosh told the Wisconsin State Journal the pipe that broke was in the building’s heating system. He said the building’s cafeteria and licensing are have been closed. He didn’t immediately return a telephone message The Associated Press left at his office. The agency is allowing employees work from home.
