Cool find! The $75-$80 is the cost per square ft of house though. I'm curious about the cost of additional elevation. I.e. to parent comment's point about "elevated" houses still being flooded because they weren't elevated enough.
I'd assume that once it's jacked, adding or subtracting vertical height is basically free.
