You should be out in force to speak to the issue....if you have anyone that has a direct link to any of the council members, you should contact them for a private meeting immediately!
A motion to pass a resolution can be done at the meeting by a "call the question" under Roberts rules of order, and with the political cover of the subcommittee "do pass" recommendation....discussion is limited and public discussion may be limited by the chair,they could float it......I suggest that a ton of folks make a point to be here at this meeting, and notify the chair that you would like to take use of the public comment period to make a statement....and then line up.....and plan on doing it again at the next one.....if you don't, this will likely pass.
