Not much happens in Oregon, but I'm pretty sure the cost of homeowners here helps rebuild there.
If the damage was wind, the insurance company (and all its policyholders) has to foot the bill. Some companies won't issue new homeowner policies in Florida. If the damage was due to rising water, the damage is covered by a separate flood insurance policy that is subsidized by the Feds (and all taxpayers). So either way, we pay for expensive beachfront property development. The Fed program was supposed to pay for itself thru premiums, but (as of 2017) it was $25 billion in debt.
