It depends. Street Tree Permits are required for planting and pruning street trees. Permits are required for major pruning of street trees (limbs larger than 2" in diameter and/or comprising more than 15% of foliage-bearing area). No permit is required for minor pruning of street trees (branches or roots less than 2" in diameter and comprising less than 15% of foliage-bearing area). Permits are generally free, except when the major pruning or removal is on an arterial street. Property owners maintain safe sidewalk and street access by pruning trees to provide 9 feet of clearance over sidewalks and 14 feet over streets. Contact the City Arborist at (509) 962-7236.
