Planting in the Rights-of-Way

Planting in the Right-of-Way


The Planting Strip

Before planting a tree on City right-of-way (ROW), you need to obtain a planting permit. The right-of-way is generally the area between the sidewalk and the street, and includes the planting strip for street trees. In areas where there are no sidewalks or curbs, considerations should include existing trees, ROW width, parking areas, and foreseeable street improvements.

Clearance Standards

Detailed information on regulations and requirements for the right-of-way can be found in the Right-of-Way Design Manual.  As trees grow, they will need pruning to provide a vertical clearance of at least eight feet over the sidewalks and 14 feet over streets and alleys.Tree Planting Clearance Standards

Please note that street signage must be clearly visible. Street signage includes regulatory, warning, transit, and other City installed signs.

Vegetation planted in the right-of-way shall not obstruct sight of signs or sight distance at corners in order to clearly view pedestrians and traffic. This can usually be accomplished by ensuring trees are planted the proper distance from the corner and meet vertical clearance requirements, and ensuring that vegetation other than trees be kept at a height of three feet or lower, depending on the geography of the location.
