Kind of a tangent...
Here in San Francisco they recent built a large condos-and-University-campus neighborhood at the Eastern edge of the city. The thing is, the whole area is subject to nearly constant high winds (blowing from the West, where you find the Pacific Ocean.) All the trees that were planted for it are now bent over, and there are some areas where it's hard to walk.
It blows my mind that the whole thing was planned out and built without regard to this basic condition of the site.
In general, we have to start thinking out all the loops and side-effects of our designs, or we wind up living in a constructed hell.
