That's the main worry I have in terms of long-term impact on home values. If the Bay Area turns into a complete desert, that would be problematic. But that's really the big environmental disaster I can think of. If there was an earthquake that didn't level the entire Bay, I actually think that wouldn't do much other than cause people to say "oh, people are scared, I'll bet prices will be down, I should buy now!"
