From the Council Administrative Officer: 

Please see the new "all things budget" web page that can be accessed via a new spotlight on the Council's web site.

 
This page will be updated regularly and contains all the information the public could want to know - schedules, bills, how to watch and listen, how to testify, information from the meetings themselves, etc.  Particularly, there is a link there for public testimony for the May 20 Public Hearing on the budget.
