A while ago folks tried to have the airfield re-classified for general aviation (GA) and met a lot of resistance from the communities around the field. It failed, as I recall, in at least three ballot measures. So it continues to operate as a 'private' airfield and you can only land with permission of the owner, or in the event of a declared emergency.
That said, the more interesting question is whether or not Google will build their 'urban support area' which was basically code for providing housing for visiting employees (in the truest of 'company town' sort of ways.) A number of people spend significant time working for Google as 'visiting experts' (think professors on sabbatical) and that effort is hindered by the challenges of finding a nice place to stay, except there is housing for a few thousand people already at the airfield (formerly 'base housing') which could be repurposed for that.
Of course if they do that, then there will be a large inflated Google ball that will chase you down and smother you if you try to leave :-)
