The City of Lincoln Municipal Code states It shall be the duty of every owner of real estate in the city to cut and clear, or clear, such real estate, together with one-half of the streets and alleys abutting thereon, of all weeds or worthless vegetation whenever such weeds or worthless vegetation shall extend more than six inches above the ground.
The Code considers this to be any uncontrolled or uncultivated growth of vegetation which is a safety and health hazard. Dandelions and bindweed are not considered a violation of this ordinance.
