In residential areas, the street trees should be trimmed to not less than 12 feet over the street and not less than 8 feet over the sidewalk so that none of the branches block any part of the sidewalk or the street. On other streets such as major arterials and collectors, the street trees should be trimmed to not less than 14 feet over the street and not less than 10 feet over the sidewalk. (Measure straight up from the inside of the curb on the street side and straight up from the sidewalk side.) For more information, please refer to the City of Beaverton Tree Planting and Maintenance Policy or contact Urban Forestry at 503-526-2237 or 503-526-2206.
