HB 631, which Gov. Rick Scott signed into law in March, "blocks local governments from adopting ordinances to allow continued public entry to privately owned beaches even when property owners may want to block off their land," according to Craig Pittman at the Tampa Bay Times.
It's been a constant battle in some parts of Florida, with property owners in some cases going so far as to try to rope off parts of the beachfront to keep people away. Three counties — St. Johns, Volusia and Walton — have passed local ordinances barring property owners from taking such action. The new law restricts any such ordinances enacted after Jan. 1, 2016.
