Are permits still required for seawall construction???

I don't think thats the right department, ...

Planning would be the correct department for inquiries about the replat of Magnolia Beach. However, I don't think anyone in planning would, or should, make a judgment call as to the legality of the wall under construction. I believe that is entirely DEP.

FG is correct about the enormous amount of erosion along the shores of Choctawhatchee Bay. I remember a quote by the late Mr. Reddick who wrote an autobiography about growing up near Four Mile Point (Sandestin/Driftwood Estates for newbies ;-) ). As an old man, he tried to find his old homestead. He finally found the stick marking their well. The well, which had been in their backyard, was approximately 75 feet out into the bay. Closer to home is the property my parents built log cabins on and operated a fish camp on in the late 1940's. The cabins are no longer there, but before the foundations were removed, part of the one closest to the bay was IN the bay. Also, I have watched my shoreline recede with every passing high tide, while my cousin's remains the same due to his long-standing sea wall. Of course, I'm still finding pottery and arrowheads, and he isn't.

Back to the regularly scheduled discussion - ask DEP.

One note, I'm speaking of bay front generally. Much has eroded into the bay, evident by the tree stumps found out in the bay.

Well since all of Florida was underwater at one point in time, perhaps... never mind.
