What's interesting is that many of the tech offices are actually adjacent to the bay (eg. Facebook's Menlo Park campus, Google's Mountain View and Sunnyvale campuses, Microsoft and Amazon buildings, NetApp, etc.) and in floodable areas [0]. It's not clear whether those companies would invest in dikes or just move somewhere else, but I'd assume the former.
