FYI: Where I'll be...

Unfortunately, that wouldn't have helped. Not when the water level outside is high enough where it gushes from a 3" floor drain as well as seeping in through the floor/walls. My sump pumps water out of a 1.5" hose non-stop at a decent clip and it couldn't keep up.

I'd have to install something like a French drain system, and have multiple sumps, some of which run on 12v battery for when the electric company shuts off power. Even then, when the water gets to the windows, it will flow in no matter how many pumps you have. To really do it right, I should pick the house up and put it on a ship's hull.
