Seattle FAQ
How many replacement trees do I need to plant if I remove a tree?
It depends on the size of the tree removed. Smaller Tier 1 trees (6-12 inches) generally require 1:1 replacement. Larger Tier 2 trees (12-24 inches) may require 2:1 or 3:1 replacement. Exceptional trees (24+ inches) have the highest replacement requirements. Replacement trees must meet minimum caliper sizes and be maintained for at least 3 years.
What if I don't have room to plant replacement trees?
If on-site replanting is not feasible due to space constraints, you can make an in-lieu payment to the city's tree fund. This money is used to plant and maintain trees elsewhere in Seattle. The payment amount is determined by the number and size of replacement trees that would otherwise be required.
