Full Breakdown

Sioux City Municipal Code § 12.12.464 lets the city manager's water-emergency proclamation, issued under § 12.12.460, prohibit watering of lawns, trees, bushes, shrubs, gardens and other vegetation outright, or restrict it to specific days: for example, even-addressed premises may water only on even-numbered days of the month and odd-addressed premises only on odd-numbered days, or to fixed weekday pairs the proclamation sets. The schedule applies only once a water emergency is proclaimed and announced through local broadcast media or a newspaper; it is not a standing year-round rule. Watering outside the announced schedule during an active emergency draws a water shutoff and misdemeanor charge under §§ 12.12.466-12.12.470.

Violations & Fines

Watering on a day the emergency proclamation prohibits is a misdemeanor, and the city manager may shut off water service to the violating premises.
