This assumes you are moving into an area fresh. But what about someone that's been there, potentially for generations?

It's one thing to say "don't buy beach front property in the Florida everglades" but what do you do with the millions who already own such property?

This came up with hurricane Katrina and Louisiana. Multigenerational communities were completely obliterated. I really don't find "the market said you should move" to be a compelling response.

It’s not the market saying that, it’s the climate. The market is just communicating it to you.

These places are no longer safely inhabitable due to rising ocean levels. People are going to have to be relocated one way or another.

Well; some solution has to be found. There are probably options other than relocation - look at Venice. But the market is signalling how much money should be diverted into finding solutions and whether it is cost-effective to do so rather than just moving.

And I have no sympathy towards the "been there for generations" argument. The circumstances of your grandma just can't be a reason for what people do in the present - it s too unfair.

Venice is an interesting example because most of the population moved off the island for obvious logistical issues. However, tourists love interesting places so the islands have not been fully abandoned. What’s telling is it’s not the kind of model that really scale as the more common it gets the less interesting it becomes.

Chicago is a more scalable model, as both raising the city and moving existing housing worked quite well. https://en.wikipedia.org/wiki/Raising_of_Chicago

For another Chicago example, there's the Tunnel and Reservoir Plan, a/k/a TARP (not to be confused with the 2008 Global Financial Crisis project with the same initialism).

The Chicago TARP was commissioned in the 1970s and won't be completed until 2029. It's cost > $3 billion to date.

A huge part of the problem is government putting its thumb on the scale and preventing the sort of cheap low quality development that makes sense in areas where it's a given that nature will flatten everything every 50yr or whatever.

Florida existed this way for 100 yr. You have lots that had a house built in 1850, wiped out in 1900, rebuilt, wiped out in 1950, replaced with a double wide, wiped out in 2000, and then the owner gets told "sorry, build a multi million dollar house on stilts with windows rated to stop a flying patio chair and a roof you could dangle the house from or F-off"

I understand that there's a desire to stop sketchy interests from billing off "disposable" construction as "this will resist a hurricane and is prob good for 100yr" and pocketing the difference before vanishing (especially among the HN crowd because they're demographics who usually get left holding the bag) but it's not economically tenable to force communities to construct above their means either by law or by proxy with provisions written into insurance and lending requirements.

Those parts of New Orleans that never bounced back are just the denser more vertical versions of those poor Florida communities. There just isn't the money there. And while you can potentially cover this with state and federal programs (e.g. FEMA), it seems like in practice they don't quite bridge the gap.

> preventing the sort of cheap low quality development that makes sense in areas where it's a given that nature will flatten everything every 50yr or whatever.

What kind of low quality development makes sense when you know it's only going to be washed away into the ocean at some random point within the next 50 years? Who is going to live in a place like that? What happens to them when they lose everything?

I have some sympathy. Those communities are valuable and should be saved where possible. However, it also doesn't make sense to keep rebuiling the same high risk locations, especially when all indications are rhat the risk is increasing.

The millions that own beach front property should accept the value of their land will decrease as it becomes harder to insure. If they don't want to lose equity, sell it sooner than later.

ndileas
Well, "compelling" isn't a good organizational principle. I'm not saying we should evict grandma at the first hint of insurance prices rising. There could absolutely be compensation for property, negotiated buyouts and moving costs, or other good policies.

For better or worse, markets are the clearest signals we have in a hugely messy world. That shouldn't prevent us from doing the best thing available, but the world is not inherently fair and safe, and it's not possible for it to be perfectly fair and safe with our current technology and psychology.

After Harvey was the first time I remember hearing about FEMA doing buyouts of property in susceptible locations just so they don't have to continue to pay each time weather moves in. A lot of times, families in these situations cannot sell because no buyer will want to purchase such disaster prone property. This government buyout at least gives the families a fighting chance to move.

Helene would make your point more forcefully since the bulk of the damage it caused happened in the Appalachian mountains more than 200 miles inland from the ocean.

It's becoming a hard bargain from a governmental point of view as well.

Does Florida have multigenerational communities?
bregma
Not white people, no. But people have been living there for at least 20,000 years so more than likely multiple generations.
