Trees in Gresham are regulated differently depending on their location, purpose, size, and type.
Regulated trees are those greater than 8-inches in diameter at breast height (DBH). Three regulated trees not in an environmental district and not qualified as required or significant, can be removed in a 12-month period through the exemption process. Removal of more than the exempted number of trees will need to go through a Type II process.
Required trees are those subject to specific standards for removal and replacement and include street trees, buffer trees, perimeter trees, landscape trees, and parking lot trees. These trees generally must be replaced and can only be removed through the Type I process. Additional information may be required regarding the reason for removal.
Significant trees are those designated by the City as having unique importance.
Trees are subject to specific standards for removal and replacement when they are in environmentally sensitive areas, such as those in the floodplain, hillside, and habitat conservation areas. These trees can generally only be removed if they are hazardous and their removal will need to be mitigated. When replacement is required, an affidavit and photograph will be submitted to the City within 6 months of removal.
