Facebook campus expansion plan clears Menlo Park City Council A bridge painted the same color as the Golden Gate Bridge, known as International Orange, connects buildings on the new Facebook campus in Menlo Park, Calif. Mark Boster / Los Angeles Times / May 30, 2012 Facebook got a big thumbs up from the city of Menlo Park, Calif., which cleared the way for the company's headquarters there to expand. The City Council voted unanimously Tuesday night to back an environmental impact report and development agreement that will let Facebook employ thousands more. Facebook will now be able to have about 6,600 workers on its Menlo Park campus, up from 3,600. It currently has about 2,200. It's paying Menlo Park millions of dollars over 10 years to cover the extra load on the city. Next, Facebook will begin negotiations for another campus that it plans to build on the other side of the Bayfront Expressway. That campus will have five new buildings, giving Facebook room for as many as 9,400 staffers. The neighboring city of Atherton is still unhappy about traffic headaches that will come with the expansion. The cities continue to negotiate. Menlo Park set to approve Facebook expansion plan
