1) Regulate urban business density in coastal cities and cities more generally limited by water.
2) More multi-core metropolises where the highest <edit: business> density is either spread out entirely, or spread to multiple districts sufficiently far away from each other.
Edit: The comment by hamandcheese showed I had forgotten this important modifier for point 2.
Regardless, manicured lawns are an environmentally bad thing on their own.
When you mentioned urban sprawl I first thought of expansion of the urban heat-island effect.
Take San Francisco, for example. We have transit. But riding at peak hours sucks and will always suck because everyone is going to the same place.
Concentration of offices downtown makes transit to anywhere else less viable - hence the only subway in SF goes to one place.
You cannot possibly have this opinion if you have.
