I remember a statistic from hurricane Andrew, that LOG homes survived intact.
I would second the dome idea, and a company named Deltec markets hurricane proof homes.
Those are round, on a raised pillar type foundation. One is located near my parents coastal NC home, and it has survived many hurricane strikes.
Every time there is an ice storm in central NC, the subject of burying power lines is raised, but Progress Energy
considers it cheaper to repair than replace, even despite the incredible inconvenience to their customers.
Good luck with Ivan!
