Municipal Code Section 17.86.010(I)(7) requires limbs overhanging a sidewalk to be trimmed to at least 8 feet of clearance and limbs overhanging the street to at least 13 feet, as part of the ongoing landscape-maintenance duty that applies to developed properties citywide.
(I) Landscape Maintenance. All landscaping shall be kept in an orderly condition, as follows: ... (7) Trees and shrubs shall not overhang or encroach upon walkways, drives, parking areas, and traffic signs to the extent that they interfere with the use of these areas. Tree limbs which overhang public sidewalks shall be kept trimmed to a height of at least eight feet above the sidewalk level. Tree limbs which overhang the street shall be kept trimmed to a height of at least 13 feet above the street level;
Full Breakdown
Section 17.86.010(I) sets the ongoing landscape-maintenance standards that apply once a project's landscaping is installed, not just at the time it goes in. Subsection (I)(7) targets tree canopies directly: trees and shrubs cannot overhang or encroach on walkways, drives, parking areas, or traffic signs to the point that they interfere with those areas, and any limb overhanging a public sidewalk must be trimmed to keep at least eight feet of clearance above the sidewalk, while any limb overhanging the street must be trimmed to keep at least 13 feet of clearance above the street.
The same subsection folds into a broader maintenance duty: lawns and ground cover must be trimmed or mowed regularly, planting areas kept free of weeds and debris, plants kept healthy through regular fertilization, cultivation, and pruning, irrigation systems kept working, and any significantly injured, decayed, or dead tree replaced within 30 days. Subsection (I)(8) separately bars overgrown canopies that block streetlights, cross a property line, tangle in overhead lines, or hit public property.
Where the tree sits in the parkway abutting a home rather than on a private development site, Chapter 8.44's separate street-tree ordinance layers on top: Section 8.44.040 makes it unlawful for a property owner to let a street tree's roots lift a sidewalk, curb, or street, or to let the tree or its debris become a danger to people or vehicles in the right-of-way, and Section 8.44.050 makes the owner civilly liable for any resulting injury or property damage, including the City's attorneys' fees if it gets sued.
Violations & Fines
A tree limb encroaching below the 8-foot sidewalk or 13-foot street clearance is a landscape-maintenance violation under Section 17.86.010(I)(7) that code enforcement can cite. For a parkway street tree specifically, Section 8.44.040 separately makes it unlawful to let roots damage a sidewalk, curb, or street, or to let the tree or its debris endanger people, property, or vehicles, and Section 8.44.050 makes the owner liable for resulting injury or damage plus the City's legal costs.
