Bob said:I don't mean to paint a bleak picture for SoWal, as the seawall situation is far less prevalent. The height of the dunes with the homes now perched on the edges would seem comical were it not all too real. I believe government to be the answer here, as the problem will only worsen until armoring of the dunes ceases. Barring some incredible luck, ultimately, many Gulf-front homes are going to be condemned. I think receiving compensation for loss to be fair, as many homeowners who built were only doing what the state allowed. Compensation should mostly be based on land value, as that value will most easily be determined. Logically, and in a perfect world, the state should renourish the beaches where it's needed and remove all the homes from the top of the dune lines. This is an expensive proposition, and it is what's best for all in the long run. I have no faith this will happen in our litigious society, as eminent domain vs. individual property rights should be well fought, being that those most able to afford legal defense to be Gulf-front owners. I would do nothing about current temporay seawalls, because it will cost the county/state greatly to fight the inevitable lawsuits. I propose to let the next storm or two illustrate the futlity of armoring a narrow beachline. When the twisted remains are lying on the beach, then the county can send the removal bill.
Excellent post Bob. I agree with all of it. I was thinking about the folly of building on these dunes the other day, while visiting a barrier island just north of Captiva. I was struck by the logic of the gulf-front structures -- built far back from the water, with walkovers leading the way over the small, low dune system. The homes are high on stilts, which would allow storm surge to theoretically run under the buildings. A major hurricane might rearrange the beach, yes, but the land where the buildings are is not going to disappear, since the surge would just run over the island, carve out new passes perhaps, and yes maybe knock over the buildings -- but one could rebuild.
In SoWal the high dunes/bluff system protects the vast majority of houses from storm surge or even needing flood insurance, but those waves have to go somewhere, and as we have seen they will just dig into chunks of the land and wash it away. I think in the building frenzy the county and state officials just didn't consider the unique nature of the coastline in SoWal and the ridiculousness of allowing these buildings to be perched so close to the dune line. It all starts with zoning, and yes the county and state are at fault here, and the only fair thing is to have the state buy out the people whose land may become unbuildable.
Blaming the individual gulf front owners for owning and building on the gulf is pointless. Most people who buy such homes have never given a thought to the nature of the coastline. They just want their slice of paradise. The people who need to have the understanding of the laws of nature are those who have allowed the development in the first place.
