Unless you can get the whole valley to jump on the bandwagon, it won’t work. The San Jose area is a megalopolis now with several communities abutting each other. If San Jose is onerous to a developer it can simply build across the street which is in another city jurisdiction.
San Jose is going to eventually be a city state county all mashed into one like San Fran. It already claims to be the capital of a mess of communities all claiming a piece of the history of the dusty old valley. There is construction activity galore occurring all across the valley. Not sure city leaders have a clue but I’d wager they all got fat campaign coffers after selling downtown SJ to the high bidders of techdom. Who needs natgas when you have gasbags like them running things?
