Tree Removal in Issaquah
What You Need To Know About Tree Removal In Issaquah
- The city generally requires a Tree Permit for most tree‑related activities: removal, excessive pruning, or “snag” creation (wildlife snag). Issaquah WA+1
- A “Significant Tree” is defined as any tree with diameter at least 6″ DBH — except for alder or cottonwood, for which the threshold is 8″ DBH. Issaquah WA+1
Small‑lot / Minor Removal Exemption
- On many residential lots, Issaquah allows a limited number of significant trees to be removed per year using a cost‑free Tree Removal Form (rather than a full permit). For example: up to 2 significant trees per year on lots up to 10,000 sq. ft.; up to 4 per year for 10,001–20,000 sq. ft.; and up to 6 per year for larger lots.
- However, a full Tree Permit (with more review and possibly mitigation) is required if: a tree is 30″ or greater DBH; a tree is located in a greenbelt / native growth protection area / right-of-way / common area / city property; the removal exceeds the allowed number; or replacement trees were previously planted (as city‑protected stock).
