The issue of sustainability has obvious ramifications for how we design our communities and the transportation system to serve it. Recent trends see people moving closer in to the urban core, and that once-dormant cities/activity centers are now attracting population. At the same time, housing in these activity and employment centers are becoming less affordable.
Can our cities and activity centers continue to attract growth without housing becoming so unaffordable that lower-income families are priced out of the market? Where, then, will these families live? Farther out where land is available and the commutes are longer, or to some other place altogether?
