General Rules

On private properties not under review for a permit, up to 9 significant trees can be removed without a clearing and grading permit. Trees cannot be removed without a permit if they are in critical areas, native growth protection easements (NGPE/NGPA), trees on public property, or marked for retention in subdivision plat documents. Removing 10 or more trees requires a clearing and grading permit.

Trees in Critical Areas

Trees in critical areas should generally be left alone unless they pose an imminent danger or hazard to people or property. Examples include dead and leaning trees, half-fallen trees, or trees dropping large branches near homes or structures. Trees that do not pose a risk should be evaluated by an arborist, and any removed trees should be left in place for ecological benefit if possible.

Trees Outside Critical Areas

Trees outside critical areas can usually be removed unless specifically protected. Check subdivision plat maps to confirm protection status. Protected trees may require replacement trees under NMC 18.16.170. Tree trimming is generally allowed outside critical areas as long as the tree is not severely damaged. When trimming trees near neighboring properties, alert neighbors first to avoid disputes.

Trees on Public Property

Trees on public property require special attention and should be reported to the City through the online form on the Report an Issue page.
