A LOT of the places north of 30A in Seagrove came with deeded beach access. Pretty sure more than half have been taken by quiet title/quick claim because the owners were probably never notified about it. Wouldnt surprise me if thats the reason the BCC has been kinda silent regarding that. All the lots on San Juan, Montigo etc. are still being sold with deeded access but you would be hard pressed to find the walkover for them.
So let me understand what you are saying.
1. Many places north of 30A came with deeded beach (interest in a private parcel of beach). You used the word - deeded access - do you mean a private walkover? If so it's semantics - private walkovers dump out to private beach parcel, why would you have a private walkover to a public beach.
2. More than half (you estimate) were removed by the private parcel owner of the access/beach through quiet title.
Mildly interesting but does not prove that any owner "took" PUBLIC property through quiet title. It would be a private matter between two private parties. Not sure why you would think the country would have any interest or right to be party to any such quiet title suit?
If you are suggesting that the deeded access was to public property - that doesn't make any sense. The county does not have any right to join a private property with an interest in public property.
If the owner with deeded access was not notified then they have a claim against the property owner, because all parties with interest are required by law to be notified.
Please correct me as I'm not familiar with the details.
