I had a leaky basement too. That house was next to a river. Sold it
and got one on a hill, with proper drainage. No more leaky basement.

you sort of have a point here about floods not really being too
surprising.

Here in Chicago if you're the lowest point on the block and your drains
are clogged, you're going to flood and that's that.

People still get shocked by this when it happens over, and over, and over
again.

Any place with a sump pit is also a warning the place has and will flood
again.
