If we're going to squeeze 6 million more people into Southern California over the next twenty years some changes
are definitely going to have to be made in land use policy. It's gonna get pretty ugly otherwise. Three or four hour commutes (one way), day long traffic jams, increased pollution, and a general decline in the quality of life that would accompany inaction would probably be just about enough to kill the California dream once and for all.
Not to get all Mike Davis on ya, but this fractured metropolis has got to pull itself together and start making some hard, potentially unpopular choices regarding population density, or disaster surely lurks right around the corner. Twenty five years is not a long time in the life of a city, and there's just not enough room for twenty million people to all have a 3 bedroom suburban home with a swimming pool and a 4 car garage.
This should get interesting.
