One thing I wonder about is if the large sprawl development can scale and is economically sustainable over long term. Looking at bay area cities finances most of them are in debt (and we're at the peak of a 10+ year economic boost in this area) and will be even into more debt in the future considering the pension obligations that they already signed up for and how even now, in a great economy, they are going behind with the required road maintenance. Let me rephrase this more clearly: in a large sprawl development, the number of road feet per person is larger (obviously) so the maintenance goes up too (although not necessarily completely linear), does the amount of local tax income also scale in a way that can maintain much larger road maintenance cost per capita long term?
