@Will Godrey Re: Miserable old git
In the US there is a thing called Eminent Domain.
The City / County / State could force the sale to the city enough land to put in a fence and a public walkway to the beach. The cost of the land would be roughly what has been his tax assessment per acre.
He's already facing millions in fines and it would solve this issue once and for all.
I don't know why they haven't attempted to force a constructive easement since the beach is "land locked" meaning that Khosla ?sp? owns all of the overland access to the beach which is public property, so he would have to grant the easement. He could put up a fence to limit their access and to keep pedestrians on the easement only.
Either way, he's being a total prick about it and will lose i court.
