This is a little old but I doubt the DOT's position on this has changed. I really thought this was a Saturday Night Live sketch when I first saw it. When DOT commissioner Janette Sadik-Khan talks about "looking for opportunities to transform spaces to green oases" she is talking about painting the sidewalk a nauseating green color. No joke. (What's the term "cars and debreeze" mean? Anyone know?)
We have the DOT commissioner greening our streets with paint, and the Parks commissioner greening our parks with carcinogenic, hot-as-hell carpets.
You gotta love it.
