Appendix F - Bushfire Hazard Assessment and Managment Report

Bushfire Report


The assessment involved an analysis of the site and its immediate 100 m radius
surroundings to determine the typical bushfire risk characteristics. It included the
application of Vegetation Hazard Classifications to vegetation located within 100 m
of the site. Where necessary, it was expanded to cover an additional area ranging
from 150 to 300 m.

According to AS3959:2018, the following vegetation shall be excluded from a BAL
assessment, which is considered as low threat vegetation and/or non-vegetation
areas:

    •   Vegetation of any type that is more than 100m from the site.
    •   Single areas of vegetation less than 1 ha in area and not within 100 m of other
        areas of vegetation being classified vegetation.
    •   Multiple areas of vegetation less than 0.25 ha in area and not within 20 m of
        the site, or each other or of other areas of vegetation being classified
        vegetation.
    •   Strips of vegetation less than 20 m in width (measured perpendicular to the
        elevation exposed to the strip of vegetation) regardless of length and not
        within 20 m of the site or each other, or other areas of vegetation being
        classified vegetation.
    •   Non-vegetated areas, that is, areas permanently cleared of vegetation,
        including waterways, exposed beaches, roads, footpaths, buildings and rocky
        outcrops.
    •   Vegetation regarded as low threat due to factors such as flammability,
        moisture content or fuel load. This includes grassland managed in a minimal
        fuel condition, mangroves and other saline wetlands, maintained lawns, golf
        courses (such as playing areas and fairways), maintained public reserves and
        parklands, sporting fields, vineyards, orchards, banana plantations, market
        gardens (and other non-curing crops), cultivated gardens, commercial
        nurseries, nature strips and windbreaks.

The assessment also takes into account the small and or isolated patches and
corridor filtering process of Bushfire Resilient Communities:

    •   Sub-hectare areas of continuous fuel (i.e. surrounded by either no fuel or non-
        continuous fuel) those are further than 100 metres from any other continuous
        fuel greater than two hectares.
    •   Downgrade the effective fuel load of continuous vegetation patches
        measuring (a) 1 to 2 hectares (by 66 per cent), and (b) 2-3 hectares patches
        (by 50 per cent) if the patch is surrounded by either non-continuous fuel or a
        low-hazard vegetation or land use type, and if the patch is further than 100
        metres from any other continuous-fuel vegetation patch greater than two
        hectares.
    •   Remove narrow corridors and areas of continuous fuel < 50 m in width that
        are not sufficiently wide to support a fully developed flame front.
