What’s the Benefit of Requiring a Permit to Remove a Tree in My Own Backyard?
Roughly a third of all the City’s trees grow on single-family lots. Before the implementation of Title 11, Portland's Tree Code, most of these trees were unregulated, with no restriction on removal and no requirement for replanting. City Code Title 11 lets homeowners easily remove problem trees (those that are dead, dying, diseased, dangerous, nuisance species, or too close to buildings) with the provision that a new tree be replanted to replace the one being removed. This will help balance removals with new trees so that the tree canopy in neighborhoods remains in balance, preserving both quality of life as well as property values.
Homeowners who want to remove a large, healthy, non-nuisance species tree that is not too close to buildings can still apply to do so, and their applications will be evaluated against the standards and review factors found in Chapter 11.40.050. In either case, the permit system provides an opportunity for the City to engage with property owners, encourage retention of large, healthy trees, provide tree care information, monitor canopy levels more closely, and ensure that trees removed are replaced over time.
