Flooding tunnels is a constant problem in DC. There so many of them they number close to a thousand. Lots of them are from the Civil War, but most are relatively modern. The Metro subway has over 100 pumping stations just to keep the tracks clear. Metro tunnels under the Potomac leak like sieves and one estimate I saw said over ten thousand gallons of water are pumped out and back into Rock Creek, The Potomac and several other now-buried old tributaries. The Pentagon basement floods regularly because it was built over a river and on swamp-land.
Off topic but I worked at denver international Airport for a company. We had our own golf cart to drive through the tunnels under the airport. It was so vast and confusing it was easy to get lost. Its amazing what the underground can hold when you cant see it above ground and have no clue it even exists.

Rather than fixing holes in the hull they just install more bilge pumps.
This happening now means we're getting close.
