It is not really that people living in Stockton already are commuting into the Bay, but Bay Area workers are being displaced into Stockton. The Bay Area has added more jobs than housing for a while now.
# Service accurate enough to set a clock by.
# Service mesh that provides walk-able freedom.
# Safety and cleanliness (both a culture and enforcement issue)
Yes, there would need to be a slight increase in density as well as much more transit service; but that metro area could scale up were there enough water.My main point is that “move the jobs” in a sufficiently large city is not generally a working way to reduce commute times.
The Bay Area is extremely special. It's the only place to go to get a good job! There are probably 500,000 people who would move in next week if we had the apartments to house them. That is absolutely not true of Stockton.
Someone who commutes to SF from Stockton isn't a resident of Stockton. They're a resident of SF who is priced out!
Personally I wouldn't want to live in SF proper even if it was cheap. Most of the city is kind of a shithole and the governance is atrocious in a way that goes far beyond just failed housing policies.
Another option would be to set policies that encourage greater economic development and job growth in Stockton so that residents aren't forced to commute long distances. There's nothing special about the SF Bay Area: it's just another place.
