Mayor Bloomberg will make "a major announcement on New York City sustainability policy," when he joins Gov. Schwarzenegger at 3 p.m., according to Streetsblog.

While details are a bit sketchy, some new hires in Deputy Mayor Dan Doctoroff's office may offer some clues.

Dr. Rachel Weinberger of U. Penn, who wrote "Transportation for Livable Cities," was recently hired as a new "Senior Policy Advisor for Transportation." Supervising her is newly hired Rohit Thomas Aggarwala, who has a PhD. in history and is described as "a brilliant politician."

Streetsblog notes, "Aggarwala has a big job ahead of him and Mayor Bloomberg hasn't left him much time to get it done -- unless, of course, he gets to continue doing it during a Doctoroff Administration."
