Bushfire Hazard Assessment - 11 Senegal Rise

5.0      SETBACKS
         Modelling has been undertaken to determine the setbacks required for a new dwelling to be
         constructed in the building envelope proposed adjacent to the existing cleared area of the site.
         The setbacks detailed below correspond to the varying construction standards under AS3959
         (Australian Standard 3959 (2018) Construction of buildings in bushfire-prone areas). The
         vegetation to the south-east of the block has been merged with the cleared land on the adjacent
         land given its separation from the balance of the vegetation to the west. To summarise the table
         below, the new dwelling will require a minimum of 20.9m separation from the retained
         vegetation within the site to achieve a BAL 40 construction standard, a minimum of 28m
         separation to achieve a BAL 29 construction standard etc.
