Bushfire Hazard Assessment & Management Plan v2 NCES REF: J000542 Lot 9 on RP225312 — 100 Cooyar Street, Noosa Heads reference that the applicable assets in the development footprint are to be separated from the closest edge of an adjacent mapped medium, high or very-high potential bushfire intensity area by a distance (APZ width) that achieves a radiant heat flux level of 10 kW/m? or less at all development footprint boundaries. The proposed development footprint intercepts the modelled vulnerable use <10kW/m? RHF setback requirement to the east by a maximum of approximately 6m and to the south by a maximum of approximately 7.8m, noting the modelled <10kW/m? RHF contour was set from the external edge of the NSC firebreak adjoining the site. The risk assessment performed herein, which also considers other factors beyond just separation, has however identified that the level of risk acting on the development could be considered to facilitate an Acceptable to Tolerable risk of impact and therefore can be supported subject to implementation of the recommendations set herein. The extent of proposed separation is to constitute the extent of the recommended APZ for the development. This means the APZ is to extend from the building edge through to the limit of the NSC firebreak on the adjoining lot, which for clarity, extends 20m from the eastern site boundary and 15m from the southern site boundary. The conditions in the APZ are to managed for the life of the development and shall: 1. Comprise only low threat vegetation (for example grassland managed in a minimal fuel condition, maintained lawns, low flammability garden beds, pathways, open space area); 2. Are 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; 3. Not include any other buildings between the new building and the limit of the APZ; and 4. Not include any timber based hard landscaping such as pergolas and breezeway framing which could facilitate a fire pathway from the adjacent vegetation onto the building. Ozcare is to be responsible for the maintenance of the APZ for the life of the development. 5.3 Water Supply The availability of a reliable water supply for firefighting purposes is a vital tool in the defence of bushfire impact. The site is currently connected to the Noosa Heads reticulated water supply which has a minimum pressure and flow of 10 litres a second at 200kPa. The new buildings will be connected to this supply and therefore the water supply design satisfies the NSC Bushfire Hazard Overlay Code requirements for water supply and that prescribed within the SPP. A fire hydrant and fire hose reel is recommended to be provided at the northern, central eastem and southern points of the site to aid in fire suppression activities. It is recommended that any new road components and fire hydrants are designed and installed in accordance with: 1. Fire Hydrant and Vehicle Access Guidelines for residential, commercial and industrial lots, Queensland Fire and Emergency Services, 2015, unless otherwise specified by the relevant water entity; and 2. The Road Planning and Design Manual 2nd edition, Department of Transport and Main Roads, 2013. Note: when relevant, the superseding versions will apply. 5.4 Fire Breaks The provision of fire breaks and fire trails within a site located in a bushfire prone area offers an important bushfire defence measure to assist in reducing the risk and severity of bushfire ingress onto and through a site. The establishment and management of a 20m fire break adjacent to the eastern site boundary (i.e., off-site) and a 15m fire break adjacent to the southern boundary has been recently approved by Noosa Council and constructed by Ozcare.
