Plants in the public right-of-way are the responsibility of the property owner.
Trim vegetation growing into or over roads, sidewalks, signs and streetlights. You must trim trees that hang over the road to at least 12 feet over the road or nine feet above sidewalks. Trim shrubs and other plants two feet horizontally away from the edge of the road.
However, don't remove or spray herbicide on plants in roadside ditches. They prevent erosion and filter stormwater.
We maintain some landscaping on newly constructed roads. We may trim vegetation in some right-of-way locations if it is hazardous to the public.
