75   Cryptocarya sp.        Native Laurel       12m        4.2m      2.9m       2.1m      Protect & retain


                TPZ: Tree protection zone
                10% encroachment of TPZ
                SRZ: Structural root zone


         3.1   The trees recommended for removal cannot be retained adequately due to TPZ’s being
               significantly compromised. Other trees for removal in the event of TPZ’s that can be protected are
               far too large to be safely retained. If retained they will be open to constant limb loss possibility
               due to exposure as a result of the removal of other adjacent vegetation.

         3.2   TPZ’s need to be determined and clearly marked out prior to any tree removals. ATF fencing or
               similar should be set out to limit root damage of protected trees.
               Tree removals must be undertaken with care and root balls should be stump ground when close
               to protected trees. Any works within TPZ’s should be supervised by the Project Arborist.

         3.3   Tree 26 is marked for removal but all steps will be taken to attempt safe retention.

         3.4   The street trees on the road reserve at the western end of the site will require removal to allow
               for stormwater/water infrastructure. 2 of these trees are small self- seeded Acacia’s along with a
               Lillypilly in very poor condition and juvenile Waterhousea.

         3.4   All retained trees require mulching of the TPZ’s using good quality forest mulch. Root pruning
               using Air spade or a vacuum excavation process is recommended for any works within 1 metre of
               TPZ’s.
