The city shall adhere to a 4-stage drought contingency plan as outlined in this division. This 4-stage plan shall be followed for a drought declared condition or a system-wide emergency.
(Ordinance 1113.1 adopted 12/3/12; 2004 Code, sec. 13.861; Ordinance 1270 adopted 3/21/19)

In spite of this redundancy, the city must be prepared to respond to any emergency water supply situation. It must also be prepared to respond to other emergency conditions occurring in the city’s system.
(b) 
Four (4) threshold levels have been identified for triggering various responses to water supply emergencies. These trigger conditions and corresponding emergency response measures are summarized in attachment D to Ordinance 1270.
(1) 
Stage 1 triggers - Customer awareness.
