Urbanists and environmentalists are natural allies. Instead of attacking each other, urbanists and environmentalists need to be saving energy to fight real enemies (The Making Cars Happy behemoth).
Speaking as someone schooled in both environmental science and urbanism, I must say that the new urbanist transect concept is one of the most powerful concepts I have ever come across, because its proper application informs us about how the entire spectrum of habitats — be they Charleston or the Everglades — is best designed. Neither the traditional discipline of urbanism or the traditional discipline of ecology incorporates the full spectrum of habitats and their needs. In principle, the transect achieves that.
The transect concept asks this question: What elements are immersive in the habitat we are working in — be it Charleston or the Everglades? For example, the transect instructs that a sidewalk is immersive in Charleston, and a “transect violation” when within the Everglades (at least the inner core wetland area of the Prairie). Conversely, a 200-acre marsh is immersive in the Everglades and a transect violation in Charleston. In other words, something is immersive if it promotes the quality of the habitat being designed. It is a violation if it harms the quality of the habitat being designed.
And frankly, this is where some of the conflict and impatience comes between new urbanists and many environmentalists. A good number of environmental advocates don’t have a conception of a transect or immersiveness. To such advocates, it is always a good idea to incorporate more nature EVERYWHERE — which fails to acknowledge that a 200-acre marsh in the middle of an in-town urban neighborhood harms the quality of a walkable Charleston. Natural features are not always immersive in all locations (it took me a while to realize that, since I came from an environmental academic background).
Let the city be a city and let nature be nature. It goes both ways. Yes, many urbanists are guilty of not taking proper care of sensitive ecosystems in their projects. But it is also true that a many environmental scientists are guilty of not taking proper care of urbanism in THEIR advocacy. Both can harm the other.
Much of our culture fails to realize that nature can, in a sense, pollute urbanism in the same way that human development can pollute nature.
