You’d also have a hard time establishing harm/loss. We’re talking land you can’t really do a lot with. Ability to build a pier isn’t really impacted much by that shift. Building there is already heavily restricted by zoning and environmental regs. You really can’t build much there to begin with, can’t plant on it. There’s not much in terms of resources to be extracted out of it. You can’t live there.
It’s underwater 50% of the time. It might not even be that much land. If you made that change here it’d be like 25 foot band of rocks running the length of the property.
Ownership of beaches is predominantly about access.
