wolfguard, lostinamerica - You can also google "Panama City hurricane proof house". It's more traditional looking. There's another on (I forget) the Mississippi or Alabama Gulf coast that was under construction, but stood when everything around it was wiped from the foundations by Katrina. It was also concrete construction.
I think the "Eye of the Storm" dome house is open on the bottom level. It's hard to see from the pictures, but one description of it said it could be used as a car port. The rounded structure does look more windproof. The one in Florida has many posts that raise it 12' above ground, but extend 28' below ground. It is (or was) being strengthened further with bracing and more hurricane clips, but the owner said he was going to remove the slab and replace it with pavers, because the surge pushed the slab against the concrete posts and cracked some. The third one, that survived Katrina, had a post-tension slab, which apparently worked, but googling to find out what that is reveals that there is both good and bad about it. The owner of the one that withstood Michael did not plan to be at home during hurricanes. He wasn't during Michael. He just installed remote cameras so that he could watch what was happening.
Myself, I think trying to survive storm surge is unpredictable at best. If you are only dealing with water, maybe you'll make it, but if the surge brings in a ship to ram against the house, it's hard to see much withstanding that. I like hills. And distance. And luck.
Agent Cooper - I could believe the hellmouth in Walnut Grove, although there didn't seem to be a lot of vampires. But Almanzo is Hank Summers? That means he has the same kind of longevity as the Mayor. This is worrisome. cc: wolfguard
wolfguard - There are an insane number of deaths and homes ravaged around the Indian Ocean every year in monsoon season. I find it hard to envision. The only saving grace is that many of the homes are fairly easily rebuilt. That was a rationale given for the rather flexible and rickety houses in Japan, at least when I was there in the late 50's. They could flex for earthquakes, but if they gave way it wasn't so hard to rebuild. Typhoons were more difficult.
The flood plain issue is, as you have noted, a difficult one. There's a flood plain near me that frequently floods. People built and rebuilt because the land was cheap. It worked in droughts. Come El Nino, it was more difficult. But finally they began to lose heart, and a city program to buy out the land is almost working. We have an area near one of our variable-level lakes that floods when the lake rises. It's a planned part of the flood control. That land is also cheap, but the people who built there built on stilts, and any part of the homes that are below the spillway level of the dam are concrete. If they flood, there are no complaints, they just pull together to clear debris and wash off the concrete. They like being by the lake that much. I feel sorrier for the people in Houston who were below some dams that had to be opened to protect the structures in Harvey. No one ever planned to do that. The people weren't told they were in a flood plain, and weren't required to have insurance.
By the coast, well, you pays your money and you takes your chances. I wondered about Rockport (Texas), where the new posh district is in a spit of land broken by little canals. The old posh district was on a road above a cliff filled with oak trees blown sideways into scrub. Big elegant houses were built in the new one. Multi-story, rock-faced houses. The old weather-beaten houses were on stilts. The new ones were not. I was at a party in one years ago, and asked about hurricanes, and the owner just shrugged and said they were 10' above the water. Then Harvey hit, and hung over Rockport for an interminable length of time. I don't know how those houses fared, but looking at Zillow, there seemed to be a lot of damage. I wish your brother would come inland for hurricanes.
