Bushfire Hazard Assessment

Bushfire Hazard Assessment
14 Serenity Close, Noosa Heads




8 SUMMARY
The Bushfire Hazard Assessment (BHA) has been prepared by Litoria Consulting on behalf
of Calile Malouf Investments for land described as 14 Serenity Close, Noosa Heads Qld
(Lots 10 and 11 on SP 195871).

The purpose of the BHA was to:

   i.   Identify and measure site-specific factors which contribute to bushfire hazard,
  ii.   Assess the extent of bushfire prone areas (post-development) and calculate:
           a. Potential fire intensity (PFI, kW/m),
           b. Radiant heat flux (kW/m2).
           c. For development within areas of potential fireline intensity or the potential
               impact buffer (100m), assess Bushfire Attack Level (BAL) in accordance
               with Australian Standard 3959:2018 Construction of buildings in bushfire-
               prone areas (AS 3959:2018).
 iii.   Where applicable, identify management measures to achieve compliance with the
        hazard and risk outcomes sought by:
           a. State Planning Policy (SPP),
           b. Noosa Plan (2020).

Bushfire hazard for the study area was modelled according to the methods described in
Bushfire Resilient Communities (Queensland Fire and Emergency Services 2019) and
Leonard et al. (2014), including the creation of a quantitative model of potential bushfire
fireline intensity (PFI, kW/m).

The fire behaviour modelling was carried out via GIS spatial modelling using rasterised
inputs described by Leonard et al. (2014):

   i.   Fuel load based on site-specific assessment of vegetation hazard class;
  ii.   Maximum landscape slope; and,
 iii.   Fire weather severity/FFDI.

As the proposed development involves changes to the configuration of vegetation within
the site assessment area, a post-development map of VHCs was necessary. The post-
development map incorporated:

   i.   the proposed development footprint,
  ii.   vegetation retention outcomes proposed as part of the development of the land,
 iii.   other differences between VHCs observed from a combination site-based survey
        and desktop methods.

Modelling results based on the AEP 5% FFDI indicated that:

   ● the subject land did not contain areas of potential fireline intensity,
