Olympia, WA Tree Protection: Heritage & Protected Trees (2026)

OMC § 16.56.020 defines a landmark tree as a tree or group of trees designated by the City because of exceptional value to residents, judged by association with historic figures, events or properties, rare or unusual species, or exceptional aesthetic quality. The chapter applies to all land within Olympia city limits (§ 16.56.030). The Director means the Director of the Public Works Department or the director's designee.

Under § 16.56.040 the property owner, a neighborhood organization or any person can nominate a tree with a map, a photograph and a narrative covering location, species, approximate age and the basis for the nomination. Notice is mailed to the owner and posted on the site for ten days. The Director inspects the tree, considers public comment and decides. Any person can appeal to the Urban Forestry Advisory Board in writing within ten days of posting. The board holds a public meeting within 30 days, and its decision is a recommendation to the Olympia City Council. Owners of registered trees get notice by first class mail within 30 days and must sign a landmark tree covenant, recorded by the county auditor at the applicant's cost.

Section 16.56.050 provides that, subject to § 16.56.060, no person shall remove or cause the removal of a landmark tree. "Remove" in § 16.56.020 includes any act likely to cause death within five years: root damage by machinery, soil compaction, excessive pruning, changing ground level, or paving within the drip-line. Section 16.56.060 requires a tree removal permit, with a Director decision within 20 working days. The owner or anyone residing or owning property within 300 feet can appeal, and the City Council decision is final. Major pruning means removing over 20 percent of the canopy or disturbing over 10 percent of the root zone within a 3 year period, and needs its own permit.
