It appears that the council has indeed decided to postpone its vote on the parking lot 13 schedule, originally scheduled to be voted on this Tuesday. Here is the email response I received from George Levanthal's office:
Thank you for your messages. We just learned that the Wheaton revitalization discussion has been postponed and will not take place on Tuesday the 20th. Feel free to keep in touch with my office to find out when it will be rescheduled.
