Mojave Water Agency, Cucamonga Valley, and other San Bernardino County water districts impose day-of-week irrigation schedules during drought emergencies. State Water Board emergency rules can override locals, banning ornamental turf irrigation entirely.
California groundwater basins serving the high desert are stressed by warehouse growth, agriculture, and population. Mojave Water Agency manages adjudicated basins under court-ordered pumping limits. During drought emergencies declared by the Governor or State Water Resources Control Board, local districts publish two-day or three-day per week watering schedules, prohibit daytime irrigation, ban runoff onto sidewalks, and may forbid non-functional turf irrigation at commercial and HOA properties. Customers receive door-tags before fines escalate. Long-term water budgets under California SB 555 push agencies toward stricter year-round conservation regardless of drought status.
Most agencies issue a written warning, then escalate to 100 to 500 dollar fines per occurrence. Repeated violations may result in flow restrictors installed on the meter at customer expense.
