NYC averages a population of 1400 people per city block with mixed use development. Pictured above in Houston they fit 126 cars per city block sized parking lot.
Yeah actually having a real public transport system snd converting a lot those parking blocks into multi family housing could help a lot
Houston is 26,061 km2 and even that doesn’t include some of the outer outer suburbs coming in from the grand parkway project. Only about a 1/10 of the that is downtown i think, almost everyone commutes in from a 45 min highway drive. There was a small push to get people to move “into the inner loop” years ago but the problem is the pricing is just astronomical. I’ve been getting pushed out further snd further from the city bc the prices are insane down there.
If we had a good sized train system that’d help a lot but the best we have are park and ride busses that no one takes bc they have a stigma of being for poor people.
