In 08 severe flooding hit Cedar Rapids. Since I work in the construction industry, I was one of the people who went around and inspected homes for safety before the public was allowed back into flooded areas. There were quite a few places with collapsed foundations because of the water pressure. After 1 day of inspecting, the city was tired of all the complaints and allowed people back to their homes in some of the outlying areas. People started pumping out their basements that were full of water. If they pumped the water out too fast, their foundations collapsed. I was told that you should only drain 2" of water out at a time. Keep doing this until the water level doesn't rise back up that 2". Then you can start pumping another 2".

Obviously things are different in that building but I wonder if similar concerns are being addressed.
