Tree Trimming Guidelines

Trees 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.

Vegetation 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.

Vegetation cannot grow into the sidewalk or street.

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