Utilities & Trees
Trees and utilities can coexist when planned properly.
Trees should be planted 10 feet from sewer, water and gas lines. You can locate the side sewer serving your property here. To locate all underground utlities, contact Call Before You Dig, 1-800-424-5555 two days before digging.
City Light employees and contractor crews work to maintain safe and reliable electric service by clearing branches, limbs and fallen trees away from power lines. Seattle City Light customers are expected to keep the line drop from pole to home or other buildings clear of trees and obstructions.
