When do I need a Certified Arborist Report? Why?

A Certified Arborist can help decide whether a public / street tree should be removed, and how to best accomplish the removal in a manner that is safe to people, property, and the community. Certified Arborists have the skills and equipment to safely and efficiently remove trees.

A Certified Arborist Report is only needed under certain circumstances, however. You do not need one if your sidewalk is buckled due to tree root growth, creating a sidewalk mobility hazard, or if the tree is obviously dead or has already fallen over. We request that you include photos of circumstances like these with your tree removal and replacement application.

A Certified Arborist Report is most often necessary when determining if trees that are not obviously dead or fallen are indeed dead, dying, diseased, and/or hazardous and thus subject to removal and 1-for-1 replacement.

Our webpage about Certified Arborists contains several helpful resources. It is strongly recommended when seeking a Certified Arborist that you hire a reputable company with current International Society of Arboriculture (ISA) certification. All contractors working in Oregon City must also have a valid business license.
