That's a fair point. Beaches should be treated like most parks. Close them at a particular time, maybe at 9 PM.
And as for the homeowners, if they don't like to see folks walking along the beach, the homeowners should build a nice high fence right at the edge of their property.
I really think they all should put up a fence. I think that this would be a good negotiation but have the city pay the fencing since they are causing the problem.
It is not a fair point because the beach is not THEIR backyard. As much as they wish it was it ain’t so. Their backyard abuts the beach. The solution is if you don’t like the openness and free flow beach traffic don’t build next to a beach.
Beaches are part of the ocean. By definition. At high tide you can be there in a boat. At low tide you're standing on dry sand. Same place. Who has jurisdiction to close the ocean?
