Federal Way FAQ
How many trees do I have to plant to replace one I remove?
Federal Way uses a tree unit system (FWRC 19.120.130) rather than a fixed ratio. A larger removed tree may require multiple unit-equivalent replacement plantings depending on the site's total required tree units per acre.
Can I pay into a tree fund instead of replanting?
Yes — when on-site planting is infeasible, FWRC 19.120.140 allows the director to accept a fee-in-lieu into the city's urban forestry account.
