Sorry, don't read this if you are feeling thin-skinned:
You can't build your way out of this one. There will always be mandatory evacuations during hurricanes.
This is another one of those growing number of areas where if you give everyone, everything that they think
they want - a great many of them will self-destruct.
As long as we have insurance companies telling us what we can and can't do and how we have to do it, people don't have to think.
As a general rule I will always run from a hurricane. Not because of the hurricane but because of the embedded tornadoes.
Here's a good little read on the subject. Not saying it has all of the answers but I enjoyed it.
