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 E2 (Lot 6).
       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 for the various vegetation communities observed
                  on the site and the adjoining site to the east following site inspection. Potential
                  fuel loads have been determined in accordance with Table 1 of the State
                  Planning Policy – state interest technical manual, Natural Hazards, Risk and
                  Resilience, A “fit for purpose” approach in undertaking natural hazard studies
                  and risk assessments

                  * Refer Section 6.1 for fuel hazard assessment details


                  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 Undulating (>5% to 10%) to Rolling Hills (>10% to 20%), with the
                  exception of the steep sand slope central to the site which is devoid of
                  vegetation.

                  5.2.3    Aspect

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