(10:05) San Mateo – In a move that could result in Silicon Valley billionaire Vinod Khosla being hit with tens of millions of dollars in penalties, The California Coastal Commission has begun an enforcement action against Khosla for his refusal to open Martins Beach in San Mateo County to the public. Khosla is currently charged with at least five potential violations, with fees as much as $15,000 a day. Because of the appellate court ruling San Mateo County Sheriff’s Office has told the public to feel free to ignore Khosla’s no-trespassing signs.
