Kirkland FAQ
Can I remove a hazard tree without a permit?
Often yes if an ISA-certified arborist documents the hazard, but trees inside critical area buffers usually still require notice or limited approval before removal.
Do I need to replace removed trees?
Yes in most cases. Replacement ratios depend on tree size, location, and whether removal occurred in a buffer or rural retention area.
Seattle FAQ
Can I remove a tree on my property in Seattle?
It depends on the tree's size and species. Trees 6 inches or larger in diameter are regulated. Removal of Tier 2 (12-24 inches) and Tier 3/Exceptional (24+ inches) trees generally requires a permit from SDCI. A limited number of smaller trees may be removed per year without a permit, but replacement planting is typically required.
What is an exceptional tree in Seattle?
Exceptional trees are generally 24 inches or larger in diameter at standard height (4.5 feet above ground). These trees receive the highest level of protection under SMC 25.11. They can only be removed for limited reasons such as documented hazard or disease, and illegal removal carries fines up to $23,000 per tree.
