In 2017, the Miami Beach Association built a fence with an entry gate and implemented a permitting system for access to Miami Beach in Old Lyme, Connecticut due to an increase of inappropriate behavior and trash. As this system placed restrictions on the public’s use of the beach, residents of Old Lyme living near Miami Beach sued the Association.
