It is unlawful for any person owning or having charge of irrigating lands in the City to so irrigate said lands that waters used in such irrigation shall be cast upon or over, or permitted to flow upon or over, any of the public streets, alleys or public places in the City; provided, however, that in the event of an unavoidable accident in the process of such irrigation, whereby the water is uncontrollable, it shall not be deemed an offense as hereinabove described if such water is prevented from flowing upon or over such public streets, alleys or public places within a reasonable time sufficient to repair such accident. (Ord. 1205 § 2, 1969; prior code § 27.202).
