What are the impacts on natural landscape setting?
- Under clause 2.2.3, for approval of a variation to front setback, the proposed setback should not have adverse consequences for the landscape quality of the streetscape.
- The potential impact of a 7.5m front setback was the subject of evidence by the arboricultural experts in the hearing, Mr James Van Breda for the Respondent and Mr Ross Jackson for the Applicant.
- A particular focus of the evidence was the potential impact of the proposed 7.5 m front setback on a group of trees at the front of the Subject Site and presenting to Saunders Bay Road.
- In particular, the evidence centred around 3 trees referred to in the evidence Tree 3, Tree 4 and Tree 5. These trees are the following species:
1. Tree 3: Cinnamomum camphora
2. Tree 4 Angophora floribunda
3. Tree 5: Eucalyptus botryoides
- The experts agreed that within this group of trees, Tree 4 was the most significant. It was the evidence of Mr Van Breda that Tree 4 had an age of between 60 and 70 years and was endemic to the Sutherland Shire. His assessment was that the tree had not been planted but was a natural occurrence on the Subject Site.
- The experts also agreed that, should the proposed development receive consent, all three of those trees should not be retained.
- There was significant discussion between the Parties and the experts in relation to the differences between a proposed development with a front setback of 7.5 m and a proposed development with a front setback at the established street setback of 11 m.
- The evidence of the experts was that in either scenario Trees 3 and 5 should be removed for differing reasons. The expert's noted that it was Council's policy to remove Cinnamomum camphora trees, such as Tree 3, where possible. The experts also agreed a development with either setback would adversely impact on tree protection zone of Tree 5 and so would require its removal.
- The experts further agreed that should a 7.5m front setback, as proposed, receive consent, then Tree 4 would not remain viable and should be removed.
- There was a difference of views as to whether Tree 4 could be retained under an 11 m front setback scenario.
- Notwithstanding this difference of opinion, in this appeal the proposed development only has a proposed front setback of 7.5 m, and it was agreed by the arboricultural experts that this would require the removal of each of Trees 3, 4 and 5.
- As a consequence I conclude that the proposed development, with its proposed 7.5m front setback, would have adverse consequences for the landscape quality of the streetscape of the subject site. Most notably this would be as a result of the removal of the group of trees, including tree 4. The experts agreed that Tree 4 was of significance in terms of its and size and age.
- I further conclude that the proposed variation to the established street setback does not meet the requirements of clause 2.2.3 of the setback controls in section 2.2 of chapter 3 of the draft DCP 2015.
