The regular agendas for the first, second, third and fifth Tuesdays of the month are essentially a consent calendar, that is, all items are automatically approved without discussion, unless a Supervisor or member of the public requests discussion of a specific item. The fourth Tuesday of the month is reserved for the purpose of conducting legally required public hearings, Board of Supervisors motions and department items continued from a previous meeting, have time constraints, or are critical in nature. Since Board meetings are considered Brown Act bodies, a Board agenda is published 72 hours before the Board meeting is convened.
