Three members of the City Council shall constitute a quorum to conduct City business at a properly noticed public meeting. Less than a quorum, however, may act for the sole purpose of adjourning such meeting to a specified future date and time. If a quorum is lost during a meeting, less than a quorum shall either recess the meeting until a quorum can be re-established or adjourn the meeting to a specified date and time. In the absence of all the members of the City Council from any meeting, the City Clerk may declare the same adjourned to a specified date and time. When a meeting is adjourned under this Charter Section 308 to any date or time other than the next scheduled regular meeting, the City Clerk shall provide special notice of such meeting in accordance with the standards provided in this Charter and the laws of the State.
