There should be a public comment period after the professional testimony. Members of the public get like 3 or 5 minutes to speak. You can’t question the attorneys or other members. It’s just your comments on the application.

This is the Landmarks Commission so they will likely be hearing two applications. One for the demo of the existing buildings and one for the design of the new tower. They will be grilling the applicant on why the existing buildings need to be demolished and how the new building fits the character of the community. So your comments should try to support those items. You’ll get a feel for what the commissioners think during their questions.
