What defines a "beach" that should have public access? A waterfront home on the ocean, Gulf of Mexico? What about homes on large bays, the great lakes, rivers, small lakes? Tim's house is on a lake, should his backyard be open to public access?
Google is your friend, try "littoral zones", but I don't think there is just one definition.
Regarding Tim, hell yeah his back yard should be open! His tribe will soon be gone and he'll be an empty nester. He should convert his place to a beach club, B&B and offer FREE horse back rides with honky tonk on Saturday night. Kinda like Juana's Pagoda south. But I doubt he even has flood insurance. Water would have to be butt deep in Arcadia for him to see a change in the lake's level.
