C. Maintenance of street trees, other than those located in the Downtown Tree Zone shall be the continuing obligation of the abutting property owner. The city shall undertake regular maintenance of street trees within the Downtown Tree Zone in accordance with appropriate horticultural practices including pruning and fertilizing to properly maintain the health of such trees. (Ord. 4816 §2, 2004; Ord. 4654-B §1, 1997).

Street trees, as they grow, shall be pruned to provide at least eight feet of clearance above sidewalks and 13 feet above local streets, 15 feet above collector streets, and 18 feet above arterial streets. This provision may be waived in the case of newly planted trees so long as they do not interfere with public travel, sight distances, or endanger public safety as determined by the city. Major pruning, as defined in MMC 17.58.020, of a street tree must be approved by the city in accordance with MMC 17.58.040. (Ord. 5027 §2, 2017; Ord. 4654-B §1, 1997).
