> It seemed to me that you could double the population density of that kind of neighborhood by replacing a single family lot with a 8 story tower every other block and filling in an occasional duplex, triplex or small apartment building. And you could probably maintain or even increase the amount of ground-level "yard" space per capita even while increasing population density. Of course it would need to be parks that you share.
