Appendix D - Bushfire Assessment · RAL26/0026

         Surface fuels and woody regrowth is to be controlled in the APZ to maintain a low fuel load
          environment. Roof tops, gutters and other areas of the building are to be regularly inspected, and
          debris removed to reduce the risk of spot fires developing during a bushfire event
         In accordance with Assessment Benchmark 7 of the SPP Bushfire, the APZ is to be designed to
          ensure a potential available fuel load is maintained at less than 8 tonnes/hectare in aggregate and
          with a fuel structure that remains discontinuous.

5.3       FIREBREAKS
A risk of fire impact has been identified to the south of the proposed building envelope. The proposed
new allotment is located approximately 25m from hazardous vegetation and is separated by the dual
carriage road formation of McKinnon Drive and associated mowed road verges. In addition, a 10m APZ
consisting of predominantly cleared open space has been recommended to be maintained surrounding
the proposed building envelope. The allotment is located on generally flat land and contains sufficient
area which is cleared of vegetation. The existing condition of the new allotment offers suitable operating
conditions for emergency services, with excellent exposure to the edge of the adjoining forest. As
Mckinnon Drive forms an effective firebreak to the south of the site, it is not necessary to construct formal
trafficable firebreaks within the development area. The development will rely on the other bushfire risk
management measures detailed within this management plan to reduce the bushfire risk to an acceptable
level.

5.4       WATER SUPPLY
The proposed development is connected to a reticulated water supply. The Unitywater Infrastructure
mapping depicts a Water Trunk Main that traverses the site. In compliance with Acceptable Outcome 3.1
of Council’s Bushfire Hazard Overlay Code, the trunk main would deliver a minimum flow and pressure of
10 litres a second at 200kPa for firefighting purposes which assists in reducing the risk of bushfire impact
to the development to an acceptable level.

5.5       VEHICULAR ACCESS
Assessment Benchmark 4 of the SPP Bushfire 2019 states that to facilitate safe evacuation during a
bushfire event, a development footprint plan should be located within 60 metres of the street frontage
and sited to enable a route between the development footprint plan and the street frontage with a
gradient that does not exceed of 12.5 percent. The proposed building envelope within the new allotment
is located approximately 10m from the boundary off Mckinnon Drive. The driveway access would direct
occupants through an area of low hazard vegetation with close connectivity to McKinnon Drive. The site
is on low grade and the allotment is of sufficient size to provide adequate turning space for fire-fighting
appliances. The available access to the proposed building envelope assists in reducing the risk of bushfire
to the development to an acceptable level.
