Slope Assessment
Analysis of 1m contours obtained for the study area indicates that hazardous vegetation areas identified to the west are located
Upslope from the proposed development. Vegetation to the east is located marginally Downslope of the subject site at a
predominant gradient of 0.0 – 4.9o.
Refer to Figure 6 for a representation of slope categorisation within the study area.

Fire Weather Severity
Following AS3959-2009 S.2.2.2 Table 2.0, Queensland's Regional Fire Danger Index is nominated as FFDI 40. However, a review of
relevant data developed by the Queensland Fire Department (QFD) in conjunction with CSIRO suggests that a regional-specific
FFDI value of 47 is appropriate for the site1. This value anticipates future climate trends to 2050 and a 5% annual exceedance
probability (AEP). As such, using FFDI 47 is considered a conservative approach to this assessment.

5.2           Reliability Assessment
Therefor Group’s bushfire specialists undertook a desktop review of the available resources to ensure the reliability of the
vegetation and subsequent hazard mapping classification. The following sections detail the outcomes of this assessment.

Hazard Area Assessment
All vegetation within the subject site and study area was assessed to identify potential fire hazards to the proposed structures.
As a result, three (3) potential hazard areas with distinct spatial, fuel and topographical characteristics were determined.
Table B below summarises these hazard areas.
All other areas within the study area have been assessed as ‘low threat’ pursuant to the exclusions stipulated in Section 2.2.3.2 of
AS 3959-2018 and have consequently been excluded from the assessment.
As demonstrated in Figure 7, vegetation hazard mapping indicates that areas within the study area meet the following
exclusionary criteria:
       ▪          Vegetation of any type more than 150 m from the site;

       ▪          Areas of vegetation less than 1 ha in area, not within 100 m of classified vegetation;

       ▪          Strips of vegetation less than 50 m in width, not within 20 m of classified vegetation;

       ▪          Permanently non-vegetated areas (i.e. waterways, exposed beaches, roads, footpaths, buildings), and

       ▪          Vegetation is regarded as a low threat due to factors such as flammability, moisture content, or fuel load (i.e.,
                  managed grassland, mangroves, and other saline wetlands, maintained lawns and gardens, agricultural
                  cropping, maintained public reserves and parklands, and windbreaks).
