Place balled and burlapped material in the prepared planting pit by lifting, and carrying it by
the rootball so that the ball will not be loosened. Set the tree straight and in the center of the
pit. All trees shall sit, after settlement, with the base of the trunk and the beginning of the
roots known as the “trunk flare” level with the sidewalk grade. If the top of the rootball is not
consistent with this area, soil will be added or removed below the rootball to make it so, and
the depth of the planting site adjusted accordingly.
