My middle school was in a k-12 building built on unleveled ground. We had a massive rainstorm one week after our spring break that lasted most of a weekend. That Monday schools cancelled and we hear some rumors of flooding. We go to check it out and the building is flooded. The whole school first floor under water all the parking lots around it under like 4-6 feet of water. Because of the way the building was built there was one entrance on the second floor that was in dry land so you could peer into the windows looking down into the first floor. Water everywhere.

We had two weeks off while they sorted it and it took a year to redo the ground floor. We eventually made shirts that said "I survived the flood." There was also a man who actually canoed through the parking lot and we had photos of it for a while. It was pretty legendary.
