(2) Re-advertise for bids; or

The work may be done by day labor under the direction of the Director, by contractor, or by a combination of the two. In any such emergency, if notice for bids will not be given, the city shall comply with the procedures in Cal. Pub. Cont. Code § 22050 (Emergency Contracting Procedures).
(B) (1) The City Council delegates its authority under Cal. Pub. Cont. Code § 22050 to the City Manager, so that before any emergency action is taken, that the City Manager will make a finding based on substantial evidence that:
(a) The emergency will not permit a delay resulting from the competitive solicitation for bids; and
(b) The action is necessary to respond to the emergency.
(2) The City Manager shall report to the City Council at its next meeting the reasons justifying why the emergency did not permit a delay resulting from a competitive solicitation for bids and why the action was necessary to respond to the emergency. The Council must also review the action at every regular meeting until the action is terminated.
