The City of Robbinsdale owns and maintains those trees growing around municipal offices and facilities, on street rights-of-way, in city parks, and in a few other isolated areas.  City Code directs the Forestry Department to plant, manage, trim, and remove these trees.  The street right-of-way typically extends inward about fifteen feet from the curb, although exceptions exist.  If you are in doubt about tree ownership on the right-of-way, and planning tree work in the questioned area, please call.   

Your trees, those growing on your property, are your responsibility.  A tree or shrub can be jointly-owned if it is growing on the property line, with near equal portions of the trunk on both sides of the line.  In this case, such a plant would be jointly-owned, meaning that the responsibility for the plant is also shared.
