Well I'm definitely not an expert and not sure about being experienced, but I simply answered the question as to WHY all the signs are popping up.
Very simply put; we never had this problem before. A few years ago, after the big TDC push at attracting other tourists to the area, we started to see an increase in what I call "disrespectful tourists". These are the one's that let their children urinate and defecate in our dunes, the take glass bottles to the beach (and leave them), they don't clean up after-themselves or their pets and are simply just disrespectful to our area. It is a lower class of clientele.
The aforementioned type of tourist then attracted the attention of the homeowners along the beach. Many then started to call law enforcement about the activities of these folks. This also took place at many of the Resort Beaches.
So the question came up about who actually own's the area where this activity was taking place and who has the authority to enforce a trespass warning on it.
Thus, the issue of Trespassing on the Beach and the Standard Operation Procedure of the Walton County Sheriff's Office, under sheriff Adkinson.
Due to the recent (past couple of years) of increases in calls to WCSO about people (tourists and locals alike) trespassing on peoples property (I'm not talking about the mean high tide line or the wet sand) a SOP was created.
The signs, a survey and GPS coordinates and other things are all part of a requirement set forth by WCSO so that a property owner can call for service and actually get some result. It also depends on the luck of the draw as some deputies will be proactive while others don't do anything. Same with TDC Code Enforcement. I don't agree with it, but its what's in the SOP.
That's why the signs are going up all over.
I'm not going to get into the State vs. Federal nonsense. If you want to go that route, go ask Greg Anchors at the State Attorney's Office for his letter he sent to the sheriff outlining the high tide line and wet sand issue.
I believe that private property owners have the right to control the property they own. If that happens to be a piece of white sand in South Walton County, then so be it.
I also believe that the public has the right to freely traverse East and West and back again, while not disturbing or disrespecting the private property as they travel.
The sky is falling mentality of some people with the beach access is overkill.
