Original Application Part 10 - Landscape Rationale & Vegetation Report [As Published] · 132008.1787

As mentioned above, many of the trees required for removal are non-endemic (mostly North
Qld) or exotic and included among these are some that are listed as weeds species.
Generally vegetation on the site and the Hastings Street frontage will be replaced with
commensurate species due to the practical considerations of construction and servicing.
Existing understorey planting comprises of a variety of local and exotic species such as
Dianella, Bromeliads, Red Edged Dracena’s, Liriope’s, Dwarf Date Palm’s, Phyllanthus spp,
Cycad’s and Raphis Palms.

The applicant acknowledges the significance of trees as character elements in the landscape
and will work in association with the design teams and nominated Council officers to
determine appropriate replacement trees as indicated in section 5 of this report. We expect
in the detailed design process that parties to the development process will note the significant
contribution in the embellishment of soft landscape elements to Hastings Street that is
appropriate to both the pedestrian environment and the existing street character.


4.0     TREE PROTECTION MEASURES

Trees identified for retention are to be retained in accordance with the following or as
otherwise specified by the Project Arborist to be appointed.

(a)     An arborist (min level 5 and ISA certification) must be appointed to implement the
        following works prior to the commencement of any site works:
                  i)       Appropriate measures to ensure that the natural hydraulic regime for
                           the protected trees tree is maintained
                  ii)      That no cutting (including cutting and filling) occurs within 2 metres of
                           the drip line of the protected trees tree unless performed by
                           vaxcavator and under supervision of the project arborist
                  iii)     The erection of hard temporary fencing around the protected trees to
                           enclose and protect the entire root zone, rhizosphere and tree stems
                           from mechanical injury, compaction / de-oxygenation and fuel or
                           chemical spills prior to the commencement of any works on the site.
                           The fence must be constructed 1 metre outside the drip line of the
                           trees tree or directed by the Project Arborist
                  iv)      The placement of signage on the tree protection fence(s) containing
                           the following wording “Significant Tree - no work is to be performed on
                           or within the drip line of this tree without the approval of the project
                           arborist”
                  v)       The treatment of compacted soils within the drip line of the trees tree
                           in accordance with standard aeration methodology to ensure that all
                           root systems are well oxygenated
                  vi)      The placement of composted mulch to a depth of 100-150mm spread
                           within the drip line of each tree
                  vii)     The tree root systems are located and clearly marked to ensure that
                           any construction work on the approved development plan is only
                           undertaken following root pruning or other remedial works / design
                           solutions recommended by the project arborist
        (b)            During the construction of the development:
                  i)       No works or activities of any kind will be allowed within the drip line of
                           the trees except for arboriculture programs supervised by the Project
                           Arborist
                  ii)      No stripping of leaf litter or topsoil within the drip line of the protected
                           trees tree unless performed by a ‘vaxcavator’ and supervised by the
                           Project Arborist
                  iii)     Any pruning works must be undertaken by or supervised by the
                           Project arborist in accordance with AS 4373 - Pruning of Amenity
                           Trees
        (c)            Prior to final inspection with the Council:
                i)          Corrective pruning is undertaken by the Project Arborist in
                            accordance with AS 4373
