I am sorry if I meant to sound like the sand issue is not a problem because it may well be, the point is this appears to be like we're missing the forest for the trees. In the past storm, how much sand was washed out of the dunes and mixed with the beach? I have heard estimates of more than 40 feet in dune width. What color was the remaining bluff sand? It was not white in Kurt's pictures, and much worse than a 7/2 in some areas. What color was the beach sand, it was white with some black. What color is the beach sand now- WHITE.
Now let's go into the present- How much sand is being placed? Sometimes more than what was lost, sometimes less and it will have an impact but as shown in Kurt's and SJ's photos, the beach recovers with sand from the Gulf that is white, probably due from washing, mixing etc. Maybe we have hit a critical point but wouldn't a future storm have a similar impact?
Now with walls, that is something new on our beaches. In the other information I have read on walls in a previous thread, it appears they could have a more long term effect on the beach, which in turn will require more sand, and the viscious cycle continues. That was the point of my email. Walls that are "neccesary" either should be built within their original permit time or made to get a "real" permit from whoever it is in the state and feds (don't know, don't care). What do you think?
