I'm trying to visualize this:
1.  The bridge is between the outside world and your driveway. 2.  The
bridge is higher than the driveway. 3.  When there's a flood, the driveway
is under water but the bridge is OK.

So... what happens to your house in this scenario?   How does the house
not get flooded by the water in the driveway?
