HALF MOON BAY  (AP) — A San Francisco Bay-area billionaire who closed an access road to a beloved beach is asking the state of California for $30 million in exchange for public access to Martins Beach at Half Moon Bay.

The San Jose Mercury News reports Vinod Khosla’s attorney Dori Yob quoted that number in a Feb. 3 letter to Jennifer Lucchesi, executive director of the State Lands Commission, which has been negotiating with Khosla to purchase a public right of way.

Lucchesi says her staff does not agree with Khosla’s price.

Yob did not immediately respond to an email seeking comment.

Khosla bought a $32.5 million beachfront property there in 2008 and two years later closed access to the beach.

A state law passed in 2014 directs officials to consider taking the right of way by eminent domain if negotiations fail.
