I would encourage and would also support any local kick-starter effort that wanted to supply temporary boat access to the beach until road access can be arranged.
Reading through this has made me dizzy;
The decision was based on a unique set of circumstances dating back to the Treaty of Guadalupe Hidalgo, which ended the Mexican-American War in 1848. The treaty essentially required the United States to recognize Mexican land grants as long as the owner filed a claim. Jose Antonio Alviso, who owned the land grant at the time, filed such a claim, and the U.S. Supreme Court affirmed it in 1859. A patent for the 53-acre beachfront property, 6 miles south of Half Moon Bay, was issued to Alviso in 1865.
Judge Buchwald ruled that Alviso's patent, handed down over the generations, extinguished all public rights to the property, including beach access rights established under the public trust doctrine in the California Constitution, which was first drafted in 1879.
So, officially a treaty is being honored (centring around a transferable title/'deed) which allows the blocking of access to the 'public' part of the beach?
Even more annoyingly this seems only to have come to light because they are no longer allowing access at all, whereas previously the 'owners' would charge only $5.
Before the sale, the beach had been owned for more than 100 years by the Deeney family, which set up the first cabin in 1918 and continued building through the 1950s. The Deeneys also built a store and began charging visitors for access and parking.
The fee to visit the beach was $5 at the time of the sale, but the new owner did away with that and instead put up the gate with a sign that said, "Beach closed, keep out."
Maybe a world-wide, rolling fund for these kinds of invasive, public space grabs?
