Tree Review

Tree protection fencingThe purpose of a tree review is to provide a process to evaluate whether mitigation proposed for tree removal is both appropriate and adequate, considering the purpose of the regulations that limit removal. Tree review also evaluates whether changes to tree preservation plans are appropriate, and determines the appropriate mitigation for trees lost due to violations of tree regulations.

When is a tree review required?

    • Trees in the Scenic Overlay Zone that do not qualify for removal under Chapter 33.480, Section 33.480.040.B.2.g, Preservation of Trees, or Section 33.480.040.B.2.h, Tree Replacement, may be removed if approved through tree review.

  • Your lot is in the Rocky Butte Plan District and you want to remove a tree that does not qualify for removal in the standards of the Rocky Butte Plan District.

    • Trees in the Rocky Butte plan district that do not qualify for removal under Subsection 33.570.040.C, Exempt From Review, may be removed if approved through tree review.

  • You want to change the approved method of tree preservation or mitigation for a platted land division.

    • Changes to the approved method of tree preservation or mitigation for a land division, where the Final Plat of the land division has been approved and recorded, may be approved through tree review. Changes to mitigation for development in the Environmental Overlay zone requires an Environmental Review.
