A. No person shall use or permit the use of water for residential, commercial, industrial, agricultural, or any other purpose, contrary to any provision of this ordinance.
B. No person shall waste water or use it unreasonably. To prevent the waste and unreasonable use of water and to promote water conservation, each of the following actions is prohibited as an unreasonable use of water, except where necessary to address an immediate health and safety need or to comply with a term or condition in a permit issued by a state or federal agency:
The application of potable water to outdoor landscapes in a manner that causes runoff such that water flows onto adjacent property, non-irrigated areas, private and public walkways, roadways, parking lots, or structures;
The use of a hose that dispenses potable water to wash a motor vehicle, except where the hose is fitted with a shut-off nozzle or device attached to it that causes it to cease dispensing water immediately when not in use;
The application of potable water to driveways and sidewalks;
The use of potable water in a fountain or other decorative water feature, except where the water is part of a recirculating system;
The application of potable water to outdoor landscapes during and within 48 hours after measurable rainfall;
The serving of drinking water other than upon request in eating or drinking establishments, including, but not limited to restaurants, hotels, cafes, cafeterias, bars, or other public places where food or drink are served and/or purchased;

14.22.020 - Water Conservation Program.¶
A. This chapter establishes a Water Conservation Program which uses five stages to address conditions and needs. The Water Conservation Stage shall be set by City Council action. All normal water efficiency programs and water conservation regulations shall remain in force during any stage, unless the City Council directs otherwise.
B. Stage One represents normal conditions; Stages Two, Three, Four, and Five represent potential and actual shortages. Stages Two, Three, Four, and Five may be triggered by a local or regional water supply shortage; production, treatment, transmission, or delivery infrastructure problems; limited or unavailable alternative water supplies; or other circumstances.
C. Stage one conservation measures are voluntary, and will be encouraged through public outreach, education, and awareness measures by the City.
D. Stages Two, Three, Four, and Five conservation measures are mandatory, and violations may be subject to criminal, civil, and administrative enforcement.
