Per Washington City Ordinances, mowing grass onto the streets and sidewalks is prohibited. Moving grass and keeping leaves and debris away from the streets and sidewalks helps prevent storm sewer draining and traffic issues. The maximum height of grass and/or weeds such as jimson, burdock, ragweed, thistle, cocklebur, or other plants of like kind shall be eight inches in developed residential, commercial, and industrial zoned districts, twelve inches in unplatted districts other than agricultural districts. The provisions of this chapter apply to all noxious weeds, as defined by The State of Iowa Department of Agriculture, and all grass, weeds, non-ornamental brush, vines, and other dense growth upon public or private property.
