Micah-
So sorry that you had to go through all that nonsense with the flooding and your insurance company...I know how frustrating that can be! I've only seen my basement flood once, and it was during a crazy torrential downpour. We had just moved into our house and the previous owners must not have cleaned out the gutters for years...the gutters overflowed the the water poured in through the basement window wells. On top of that, the sump pump that drains our basement failed at the same time so we had 3-4" of water in the basement when we started to pump it out.
I'm curious if it was the same storm system that caused the flooding in my house and your house (I live just to your south-west in Bloomington)...this would have been the spring of 2004.
