I agree with Eugene
In our hot region, people used to have a basement in almost every house. It was a primitive application of geothermal air conditioning. Now, building costs and leaking water has made this option problematic.

Off course, it is not a wise choice in easily flooded area.

Thats where plans change based on the situation you are presented with. But for bugging in during a summer power outage heat wave or a tornado it can be a good plan. Heavy rain and flooding, then you probably want to evac the house anyway.
