Moffett Field isn't in Mountain View. It is in Santa Clara County. It only exists because Sunnyvale purchased the land back in 1930 then sold it to the Navy for $1 so they would base dirigibles there.

That is an interesting point that Moffett Field is unincorporated. The Navy turned that property over to NASA which has developed offices and universities along with Google as tenants. Significant housing growth is planned there. It lies within Mountain View Los Altos HIgh school and Mountain View Whisman School districts. For that housing absolutely no tax revenue will flow to either district.

That's kind of the point of the state wide housing push for both more housing and more tax exempt affordable housing. All districts throughout the state have to contend with the costs of educating residents of the new housing. At the same time though housing units are producing many fewer students than they once would have..... something like 35% fewer students per unit.

It's worth noting that more of the student growth is expected to come from the below market rate units. Google and developers recently switched things around to where there are two large all affordable projects of housing being built up there. Neither of theose projects will produce any revenue in the way of property taxes. Something like 25% of new houses being built in the state will be exempt from paying property taxes......
