I'm working off the rumors [0] that California has a massive long term problem which is generally being ignored by successive governments. I don't see how they can sustain an emergency preparedness program if they have that sort of business-as-usual preparedness problem. Step 1 to me is always be prepared for the most-likely future case, then step 2 is prepare for progressively less likely scenarios.
