Information response

Mitigation recommendation measures have been made in the submitted report based on a
combination of siting, building construction, landscaping and access for fire fighters to
adequately respond to the determined bushfire hazard. The amended landscape plans now
include greater detail on required bushfire mitigation measures. Please refer to the attached
landscape plans prepared by Anembo.

Issue - Bushfire

It is noted the adjacent vegetation is mapped as RE12.9-10.1 - Tall open forest.
Canopy species include Eucalyptus resinifera, E. grandis, E. robusta, Corymbia
intermedia +/- E. microcorys, Melaleuca quinquenervia, Syncarpia glomulifera subsp.
glomulifera and Lophostemon confertus. Occurs on Cainozoic and Mesozoic
sediments. (BVG1M: 8a). This regional ecosystem can attain heights in its mature
phase of greater than 30+ metres in height.


Information Required

4      Demonstrate how the development will achieve the Natural Hazard Overlay
       Code Probable Solutions S7.1 a) ii) with respect to achieving setbacks from
       hazardous vegetation of 1.5 times the predominant mature canopy tree height
       or 10 metres whichever is the greater.

The siting of the building on the allotment takes advantage of the clearing within the Energex
easement to the east. The distance to the remnant vegetation from the building façade is
now as follows:

North: 24m
East: 55.4m
West: 24m (new open space conservation zone)

The primary threat from large fires is from the east. In this direction a 1.5 times the
predominant mature canopy tree height break has been achieved. Please refer section B-B
of the amended Anembo plans.

The adopted 24m setback to the north and west has been adopted in the site design to
achieve a BAL of 19 using method 1 of AS359:2009. This is a lower level BAL and
recognises the need to balance fire break size with conservation objectives.

The bushfire report previously submitted addressed siting and mitigation based on the 3
primary bushfire attack mechanisms being flame, radiant heat and ember attack. These
recommendations when used in combination provide appropriate siting to protect buildings
and people in a serious bushfire event.

Table 2 outlines the mitigation measures to maximise the protection of people and property
during the passage of a fire front.
