HALF MOON BAY, Calif. (AP) — California's Coastal Commission is seeking public comment on the use of a popular San Francisco Bay Area beach at the center of a lawsuit over public access. The commission announced Thursday that it has opened its website to ask people how they have used Martin's Beach in San Mateo County, the San Jose Mercury News reported (http://bit.ly/1lBnMe6 ). A judge is deciding whether Silicon Valley billionaire Vinod Khosla, who bought a secluded cove south of Half Moon Bay for $32.5 million in 2008, is allowed to close an access road and keep the beach off-limits.
