HALF MOON BAY, Calif. (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.
