I can’t get the original article to stay up on my screen so that I can read it. How did this happen?
Here it is:

Kids were in basement. When a 2” water main feeding the school is compromised that is prob 1000 gals a minute being flowed into the basement. This is just an estimate on the volume of water flowing to the basement and the piping size but I would say a 2” main would be needed to operate the facility. Bricks and mortar look strong and are to a certain degree but not against 200+ mile an hour winds. Plus you have the cave in factor of the materials falling in on those below.
All one can say is “ It was a bad decision, A basement can seem the safest place but depending what is on top of that basement, Feeding that area it can be fatal”
