A comment about Florida population growth, tourism and its effects on traffic and such. Tourism is the backbone of. the Central and South Florida economy. Without it we would have a poor economy, few retail outlets and restaurants, falling property values, and widespread hardship. Having seen that elsewhere, tourism and population growth - and traffic - is better IMO.
What he actually said in his comparison was that banks continue to issue mortgages in earthquake zones, so he doesn't see why they wouldn't continue to issue them in FL.
His comment was mortgage lenders are highly exposed in California, because few mortgage holders have earthquake insurance, and Florida has a similar catastrophic exposure to mortgage lenders.
The risk to California mortgage lending, as expressed in the article, is exaggerated. Mortgages are securitized, so the ownership is highly diversified. While a loss might be large, it is spread over many investors. If anything, underwriters might be exposed, but they are (presumably) experts at risk assessment. In addition, even a catastrophic earthquake would not affect the entire state. Commercial real estate probably represents a greater financial risk, and there much ownership is also diversified using REITs. There are many serious risks in California, but IMO mortgage lending loss from earthquakes is not among the most serious.
The risk in Florida is much different. There already is a risk of catastrophic damage, caused by hurricanes, and this has not affected mortgage lending at all. Mortgage holders in flood zones are required to hold flood and wind insurance. The current flood policies would probably insure against the consequences of sea level rise, so this risk is in no way similar to that of California. What should happen if sea levels do begin to rise is premiums for flood insurance will rise as well.
Sea level rise is a slow, unstoppable process, not a sudden catastrophic event. Exodus from affected property areas will begin before the level of damage is significant, and property values will probably spiral down is a slow, torturous process. Property owners will lose, as will children of Florida coastal homeowners hoping for real estate based inheritance.
I think the thread topic is legitimate, and people need to think carefully before settling into some areas because of the ongoing risk of water damage, sea level rise, lack of infrastructure and awareness of community leaders.
