Cal. GOV § 11125.5

(a) In the case of an emergency situation involving matters upon which prompt action is necessary due to the disruption or threatened disruption of public facilities, a state body may hold an emergency meeting without complying with the 10-day notice requirement of Section 11125 or the 48-hour notice requirement of Section 11125.4.

(b) For purposes of this section, “emergency situation” means any of the following, as determined by a majority of the members of the state body during a meeting prior to the emergency meeting, or at the beginning of the emergency meeting:

(1) Work stoppage or other activity that severely impairs public health or safety, or both.

(2) Crippling disaster that severely impairs public health or safety, or both.

(c) However, newspapers of general circulation and radio or television stations that have requested notice of meetings pursuant to Section 11125 shall be notified by the presiding officer of the state body, or a designee thereof, one hour prior to the emergency meeting by telephone. Notice shall also be made available on the Internet as soon as is practicable after the decision to call the emergency meeting has been made. If telephone services are not functioning, the notice requirements of this section shall be deemed waived, and the presiding officer of the state body, or a designee thereof, shall notify those newspapers, radio stations, or television stations of the fact of the holding of the emergency meeting, the purpose of the meeting, and any action taken at the meeting as soon after the meeting as possible.

(d) The minutes of a meeting called pursuant to this section, a list of persons who the presiding officer of the state body, or a designee thereof, notified or attempted to notify, a copy of the rollcall vote, and any action taken at the meeting shall be posted for a minimum of 10 days in a public place, and also made available on the Internet for a minimum of 10 days, as soon after the meeting as possible.
