4.6 Field Verification
As stated, S5 Environmental’s Senior and Graduate Ecologist conducted a site inspection of the site
and surroundings lands, vegetation communities, slope angles and aspects on Thursday the 12th of
October 2017 and verified the on-ground site conditions.
4.7 Severity of Bushfire Hazard
In accordance with SPP1/03 Guideline – Mitigating the Adverse Impacts of Flood, Bushfire and
Landslide Appendix 3, the scores for the individual factors determined for vegetation community, slope
and aspect have been summed to provide a total for each sub-unit as follows:
Total hazard score = vegetation community hazard score + slope hazard score + aspect hazard score.
The total fire hazard scores calculated for the site as per the SPP1/03 Guideline are shown below in
Table 4, below. The scores for the individual factors determined for vegetation communities, slope
and aspect have been summed to provide a total for each sub-unit.

Note:
* Current Vegetation Score / Future Vegetation Score
In accordance with the SPP1/03 Guideline, a total fire hazard score of 13 or greater is considered to
be ‘High’ bushfire hazard areas, a total fire hazard score of 6 to 12.5 is considered ‘Medium’ Hazard
Areas and a hazard score of 1 to 5.5 is considered ‘Low’ Hazard. Therefore, under the current
conditions the site itself is considered a LOW to MEDIUM Bushfire Hazard Area. After completion of
development works, assuming the future landscaping conditions will be in accordance with those
