5.0    FIELD BUSHFIRE HAZARD ASSESSMENT

        5.1       Methodology

        Methodology was generally based on established best practice Bushfire Management
        Guidelines.

        5.2       Site Assessment

        Duke Environmental performed a Site Assessment on 19 October 2015 for
        approximately two (2) hours over the site and adjoining Precinct F (Lot 7).
        Methodology employed was aimed at providing a field based assessment of the site in
        terms of bushfire hazard, relevant to the proposal. The site was assessed, generally
        against the following criteria:

                 Estimated Fuel Load (t/ha);
                 Slope;
                 Aspect; and
                 Vegetation.

                  5.2.1   Estimated Fuel Load (t/ha)

                  Fuel loads were estimated within the various vegetation communities present
                  on the site. Methodology employed has been adopted from the South East
                  Queensland Biodiversity Consortium Fire Management Operation Manual
                  2002 (FMOM). Table 5.1 below summarises estimated fuel loads adopted for
                  vegetation on the site.

                  * Refer Section 6.1 for fuel hazard assessment details
                  Although the level of leaf litter (surface fuel) varied throughout the site, a “high”
                  fuel hazard rating has been applied as a conservative measure.

                  5.2.2   Slope

                  The site assessment confirms the general details of the desktop assessment
                  regarding slope. The site was observed with topography generally analogous
                  with Rolling Hills (>10% to 20%) on the site and Undulating (>5% to 10%) to
                  Rolling Hills (>10% to 20%) on adjoining Lot 7.

                  5.2.3   Aspect

                  Site assessment confirms that the building envelope is characterised by a
                  westerly aspect.
