You should also know where your side sewer line is located before digging your planting hole. If you are unsure where your side sewer is, you may call the city's Engineering Services Department at 253-841-5577 or hire a private utility locate service. Plant your tree at least 7.5-10 feet away from your sewer and water lines.
In addition, your planting strip must be wide enough to accommodate the species you chose (see minimum planting strip widths on the available trees list). The city does not allow trees in planter strips between the curb and sidewalk if the planter strip is narrower than 4 feet. Trees planted under power lines must be less than 25 feet at maturity (small shade tree).
The city will also consider the proximity of other trees in the area, make sure new trees are planted far enough apart that they have room to grow, and make sure they are not too close to structures like driveways. Not all locations are suitable for a tree. If your street tree permit is denied, we may be able to work with you to select a more appropriate tree for your planting strip (depending on species availability). You are allowed to apply for up to three (3) trees, so consider all of the available planting locations around your property before completing your application.
