Contra Costa is full of open space and I believe that many of the cities from Walnut Creek out would bend over backwards to pull in these types of jobs.
There's a mini-silicon valley shaping up in the East Bay along the 580/680 corridor - towns like Dublin, Pleasanton etc are growing rapidly with existing companies and new ones - Oracle, Workday, Snowflake etc are all there.
It helps that they are also much more new housing friendly than SF and SV.
Right! I wasn't thinking about stuff like Bishop Ranch being down there. Yeah, it really does seem like most of the freeway/transit-connected East Bay towns beyond the hills would be very amendable to this type of growth. It really seems like the only exception would be the arc from Orinda to Danville.
