The purpose of this is to regulate the cutting of trees in order to help preserve the wooded character of the City of Portland and protect the urban forest. It is not the intent of this Chapter to regulate the cutting of trees on any single-family lot, which cannot further be divided, upon which a single-family residence already exists. Further, it is not the intent of this Chapter to require a permit for tree cutting in situations where the same activity is already regulated and reviewed by other provisions of the City Code.
