Schedule B: Plant Layout, Spacing & Support

General Requirements

  1. All plant material shall be located as shown in Schedules B.1-B.6 except where obstructions overhead or below ground are encountered or as specified by the Commission.

  2. Immediately following planting, to prevent excessive motion, all trees shall be braced in an upright position, using guy wires or stakes with ties, as shown in Schedules B.7 and B.8. All materials used in tree support shall meet the following specifications.

    Schedule B.7
    2.1 All support stakes shall be equally spaced about each tree, shall be pressure treated, be standard 50 X 50mm, and a minimum of 2440mm in length.
    2.2 Support stake shall be driven vertically into the ground a minimum of 940mm and support at least 1500mm of the tree stem.
    2.3 Double strand, #12 gauge galvanized wire shall be used to connect each support stake to the tree stem. Wire will be twisted to take up slack and prevent excessive motion of the tree.
    2.4 12mm reinforced black rubber hose shall be used to encase support wires and prevent direct contact with the bark of the tree.

    Schedule B.8
    2.5 Three guy wires shall be spaced equally about each tree at approximately 120 between each guy. Each guy shall consist of two strands of galvanized #12 gauge wire and be attached to the tree at an angle of approximately 45 at about 1/3 to 1/2 the height of the tree.
    2.6 12mm reinforced black rubber hose shall be used to encase guy wires and prevent direct contact with the bark of the tree.
    2.7 Each guy shall be anchored in the ground using 50 x 100 x 900mm notched stakes which have been driven into the ground at an angle so that the tops of the stakes are at least 150mm below finished grade.
    2.8 Each guy shall be made taut using 150mm turnbuckles.
    2.9 Brightly coloured flagging tape shall be attached to each guy for the duration of the tree support.

  3. Tree stakes and guy wires shall be removed once the trees are stable. Tree stakes and guy wires should remain for a maximum of two years.
