I can only assume it will go higher. We need to push FEMA to have a 2 and done rule. After that the property must be returned back to dunes/parks/public spaces.
After floods or wildfires or tornadoes or earthquakes, you'll see some buildings are a pile of rubble and others just need brushed off.
These locales should be making these requirements a part of their building codes. But I suspect they are addicted to FEMA money and actually prefer having local stimulus in their economies every few years.
