Attachment 5 - Bushfire Hazard Assessment & Management Plan

Bushfire Hazard Assessment & Management Plan v1                                  NCES REF: J000542
Lot 9 on RP225312 – 100 Cooyar Street, Noosa Heads



        7.47kW/m2 RHF from VHC 22.1 to the north;
        13.47kW/m2 RHF from VHC 29.2 to the south-east (based on 30.6m separation); and
        12.89kW/m2 RHF from VHC 34.5 to the east (based on 25.6m separation).
Whilst the RHF exposure is >10kW/m2 the following circumstances are deemed to reduce the
potential severity of impact that may arise as a result of the identified risk (additional context
to the below mentioned circumstances is provided in Section 5).
        All emergency services required during a bushfire event are located directly adjacent
         to the site to the west including Noosa Heads Fire & Rescue Station, Noosa Heads
         Police Station, and Queensland Ambulance Service;
        The proposed development will be connected to town water hence have a pressurized
         reliable supply of water in an emergency;
        No increase in the number of people living or congregating on premises is proposed;
        Formed sealed access points are available to the north and south perimeters of the
         site and the development design proposes a continuous, level, unsealed, trafficable
         firebreak trail along the eastern boundary which will connect to the sealed access
         points, thereby facilitating direct access to a potential fire front for fire suppression
         purposes (refer BF04 green linework);
        The developer proposes to voluntarily design the building to the applicable AS3959
         2018 BAL construction standard hence the building could be expected to withstand the
         radiant heat flux and ember attack for the modelled bushfire conditions (refer Section
         6);
        Fire hydrants and fire hose reels will be installed along the eastern and southern
         perimeters of the boundary, noting one is already present along the eastern elevation
         of the existing building;
        A specific Bushfire Evacuation Plan has been prepared for the project (refer NCES
         BEP 2022) to assist in the management of people during a bushfire emergency;
        A linear suite of low flammability trees have been retained within the NSC approved
         fire break to the east (predominantly she-oaks and cheese trees) and within Ozcare
         land to the south, which offer a low flammability radiant heat flux and ember screen
         against fire and ember ingress from an encroaching fire; and
        Future landscaping within the site can comprise low flammability species to further
         reduce the likelihood of spot fires development adjacent to the building.
The degree of risk acting on the current building has been historically much higher prior to the
implementation of the current firebreaks and the new building represents only a slight
expansion on the existing building footprint. Therefore, with consideration given to the degree
of proposed separation approaching <10KW/m² RHF exposure and the above highlighted
mitigating factors, the overall risk acting on the proposed replacement building and people
therein could be reasonably argued to be Likely and Acceptable -Tolerable.
