23. I bet when the waters rise they will be like Stiltsville

If I were stupid enough and had enough money to buy into coastal property in Florida, that's what I would plan for.

Stiltsville is a group of wood stilt houses located one mile south of Cape Florida, on sand banks of the Safety Valve on the edge of Biscayne Bay in Miami-Dade County, Florida. The structures stand on wood or reinforced concrete pilings, generally ten feet above the shallow water, which varies from one to three feet deep at low tide.

Stiltsville's frontier era ended with Hurricane Betsy in 1965. Beginning in August 1965, the state of Florida required building owners to pay $100 annually to lease their quarter-acre circular "campsites." No permits for new construction were issued, and structures that sustained more than 50-percent damage could not be rebuilt. Building codes were implemented and the state banned commercial operations after 1969.

I'd build my house on deeply based pylons with the living floor level well above the current highest known storm surge. I'd also build it to withstand 150-200 mph winds with self sustained power and alternate sewage handling. Water might be a problem, maybe research desalination methods.

Note: My husband attended a party back in the late 1970s, early 1980s at the A-Frame house mentioned in the article and visible in the picture from Wikipedia above. A friend of a friend knew the family that owned it and had owned it since it was originally built.
