Concerns About Tree Safety
One of the leading reasons given for tree removals is the health or safety of the tree. To ensure you are not needlessly removing an otherwise healthy tree, consult a qualified certified arborist or certified forester. There are two websites that can help:
Tree ownership is determined by whose property the trunk stands completely on. If the tree is a boundary tree (the trunk straddles a property line), it is owned jointly. In most cases, property owners may trim branches and roots which encroach on their property if they stay within certain guidelines: trim only up to the property line; do not enter the owner’s property without permission; do not destroy or damage the tree by trimming roots or branches.
If you have a dispute with your neighbor, call the Mediation Program at 425-452-4091. They can help you explore your alternatives, coach you on how to negotiate with your neighbor, or provide free mediation to help you and your neighbor find a workable solution.
Tree Removal on Public Property
The public is not authorized to remove (or reduce) any vegetation, including trees, from any public property, including any trees or vegetation adjacent to your own property. If you are unsure whether a tree is on public or private property, refer to your property title report or contact the Right of Way division.
Contact the city if you are concerned about the health or safety of a tree. The city has foresters and arborists on staff to respond to your concerns.
To report a potentially unhealthy tree on park property, call 425-452-6855 or email firstname.lastname@example.org. To report a potentially unhealthy tree in the public right of way, call 425-452-7840.
You may face civil penalties, including fines up to three times the assessed value of the trees involved, for removing, topping or otherwise pruning a tree on city property without permission. Depending on the circumstances, criminal charges may also be brought.
