In my LTHO (less than humble opinion) (or Long Term Hydrology Outlook):
Los Osos development should not proceed until desalinated water is nuclear powered and distributed to Los Osos by the plant down the coast. Then, those wealthy enough to subsidize desalination can build all the mansions they want. Let THEM suck yellow cake! (Uranium, that is). Leave the basin water for the rest of us.
