§ 8-38. Triggering criteria for initiation and/or termination of drought response stages.
The city administrator, or his/her designee, shall monitor water supply and/or demand conditions and shall determine when conditions warrant initiation or each stage of the plan. Public notifications of the initiation or termination of drought response stages shall be by means of publication in the local weekly paper, publication in a daily, regional paper, televised announcements, or mailed notifications, as appropriate to the situation.
The triggering criteria described below are based on the ability of the city to deliver treated water to the customers.
