Tree Trimming Guidelines

  • Property owners are responsible for the care and maintenance of street trees located in the public right-of-way next to their properties.

    Here's how to to keep your trees, shrubs and vegetation in compliance with City codes.

    Basic guidelines

    • Trees and shrubs must be at least 8 feet above the sidewalk, and 12 feet above the street.
    • Vegetation must not block views for at least 150 feet from stop signs and other signage.
    • Vegetation cannot grow or hang into the sidewalk or street.

    Why do I need to trim my trees?

    • Pedestrian and vehicle safety: Overhanging trees and vegetation can block views of stop signs, oncoming traffic and street signs. Bikers and pedestrians can get hit by low-hanging branches.
    • Allows for essential services: Garbage pickup, mail delivery, street repair and street sweeping are impacted if overhanging vegetation is in the way.

    How to trim your tree

  • Step 1. Measure your tree

    Picture showing measurements of 8 feet between tree limb and sidewalk and 12 feet between tree limb and streetTrees and shrubs must be at least 8 feet above the sidewalk, and 12 feet above the street.

    Measure the height of the lower branches on your trees or other vegetation in the public right-of-way, and those on your property's edge.

    An inexpensive piece of PVS pipe, cut or marked at 8 feet and 12 feet, can help you determine if trees need to be trimmed.

    Step 2. Don't block signs

    Picture showing a tree limb blocking a stop signVegetation must not block views for a minimum of 150 feet from stop signs and other signage.

    If a stop sign next to your property is partially blocked, it violates the City's ordinance for visibility and must be trimmed.



    Step 3. Don't block sidewalks

    If vegetation is blocking the sidewalk, it must be trimmed back flush with the edge of the sidewalk and curb.
