3.       FINDINGS



3.0      Proposed boundary retaining wall at 10 Surfside Ct. Sunshine Beach borders Council riparian
         buffer Lot 400 on RP810724.
         Engineering methodology involves the construction of a wall using a post and pier design with 1.5
         metre and 2.7 metres spacings. This will allow tree roots to grow beyond the boundary line and
         would greatly reduce or almost eliminate the excavation of or damage to existing tree roots.

3.1      Tree species located in the riparian buffer are varied but predominantly consist of Eucalyptus
         robusta “Swamp Mahogany”, Hibiscus tiliaceus “Cottonwood” and a Ficus lyrata “Fiddleleaf Fig”
         and are classified as early mature.
         The construction methodology proposed will cause very little, if any, damage to the root systems
         of these trees.

3.2      The boundary area of the riparian buffer is heavily overplanted with many trees encroaching
         private property at number 10 Surfside Court.
         There are potential issues with the root system of the exotic Fiddleleaf Fig causing damage to the
         underground sewerage assets located on 10 Surfside Ct. This could be addressed during the
         excavation/ pier boring process of the retaining wall.

3.3      Comments relating to the Biodiversity, Waterways and Wetlands overlay code.

         Paragraph b. c. and d. The existing habitat and the ecological values on the adjoining site will not
         be diminished at all by the proposed work on the boundary line therefore no further provisions
         will be required.
         With reference to AO3.2 There are no habitat trees located in the area near the proposed site

         With reference to AO4.1 a. Trees will be flagged prior to construction. d. Covered in findings 3.0

         With reference to AO4.4 The minimal groundwork according to the engineering details will not result in
         the removal of any vegetation that would cause such erosion.

         With reference to AO5 a. to f. No wildlife refuges or movements will be impacted by the development.

         With reference to AO6.1 a. b. and c. The proposed work will be accessed and carried out entirely from
         the private property side of the boundary so no vegetation on the riparian buffer area will be impacted.

         With reference to AO6.2 Refer to AO6.1



4.       RECOMMENDATIONS


4.0      Recommend some minor root pruning as/if required during the post installation. There will also
         be some pruning required to reduce encroachment from the boundary.
