1     INTRODUCTION

1.1       Background
This Bushfire Management Plan has been prepared to manage the degree of potential bushfire
hazard and associated risk acting on Lot 189 on MCH1261 located at 64 Reserve Street,
Pomona, Qld (herein referred as ‘the site’).

1.2       State Planning Policy Bushfire Intensity Overlay Map
The site is mapped under the State Planning Policy (SPP) (refer to Plate 1) as containing the
following Potential Bushfire Intensity areas:
      •    High Potential Bushfire Intensity area; and
      •    Potential Impact Buffer.




                               Plate 1 – SPP Bushfire Intensity Mapping Overlay

1.3       Development Proposal
The applicant is seeking to construct a primary dwelling in the western site extent. The Plan of
Development is included as Appendix 1. The dwelling is proposed within the NC Bushfire Overlay
hence triggers an Material Change of Use application which in turn triggers the need for this
Bushfire Management Plan (Noosa Council 2021).

2    Site Description

2.1 General
The site covers 1.58ha and is flanked by Reserve Street along the western boundary. The
majority of the site is characterised by native vegetation dominated by open forest species.
The site is zoned as Rural Residential within the Noosa Plan 2020.
Plate 2 depicts the site’s extent and position in the landscape.

2.2 Topography
The slope of the land is a major determinant of fire behaviour, particularly the slope of the land
under vegetation that contributes to bushfire hazard. Fire burns faster as it travels up slope, via
preheating of unburnt fuels ahead of the fire, increasing the rate of spread and fireline intensity.
Conversely, fires move more slowly as they travel downslope. Fireline intensity (kW/m) is a
function of the rate of spread (QFES 2019).
The landform declines from west to east through the site with gradual slopes of approximately 1º
recorded. The effective slopes are upslope to the west, across slope to the north and south and
downslope to the east.
Plate 3 depicts topography conditions within and adjacent to the site.

2.3 Vegetation
The following vegetation hazard classes (classified in accordance with QFES (2019)) were
identified within the site:
    •    Vegetation Hazard Class 8.1 – Wet eucalypt tall open forest; and
    •    Vegetation Hazard Class 9.1 – Moist to dry eucalypt open forests on coastal lowlands
         and ranges.

The distribution of observed VHC’s is detailed in Plan BAL01- Vegetation Hazard Classes.

3    HAZARD ASSESSMENT

3.1 SPP Fireline Intensity Class Validation
An assessment has been undertaken to validate the SPP High Potential Bushfire Intensity Class
mapped across the site. Table 2 details the SPP Potential Bushfire Intensity classes and their
corresponding potential fire-line intensity (kW/m) values as prescribed within Leonard et. al. 2017
and QFES 2019.
Table 2 - Potential Bushfire Intensity classes




The Potential Bushfire Intensity Class is primarily influenced by slope conditions (i.e., topography)
and vegetation type fuel loads.

3.2 SPP Intensity Class Validation

Based on observed conditions, the SPP mapping correctly maps VHC 8.1 as the applicable
vegetation class on the site, however, neglects the narrow band of VHC 9.1 in the western site
extent. The assigned high potential fire line intensity class is accurate for the VHC 8.1 area given
the across slope conditions but is expected to be exaggerated for the VHC 9.1 area.

Flamesol modelling was subsequently undertaken to validate the potential fire line intensity based
on the point of reference slope conditions underlying the hazardous vegetation. Table 3 summarises
the input data used:

The bushfire model output results identify that the VHC 8.1 produces a fireline intensity of 33,875
kW/m irrespective of flame width and therefore represents a High Potential Bushfire Intensity class
under the SPP (i.e., 20,000 – 39,999 kW/m).
The VHC 9.1 produces a fireline intensity of 15,866 kW/m irrespective of flame width and therefore
represents a Medium Potential Bushfire Intensity class under the SPP (i.e., 4,000 – 19,999 kW/m).

4    BUSHFIRE IMPACT REDUCTION MEASURES

4.1 General
The following section describes bushfire impact reduction measures to be incorporated into the
proposed development to reduce the risk of bushfire impacts to people and property. Implementation
of the identified measures is not implied nor intended to advocate that building occupants remain on
the site during a bushfire event, nor that people and property will be protected from bushfire impacts.
The measures are intended to reduce the potential severity of bushfire impact to the development
and not prevent bushfire impact. The bushfire mitigation measures have been derived from:
    •    Department of State Development, Manufacturing, Infrastructure and Planning’s State
         Planning Policy – State interest guidance material – Natural hazards, risk and resilience –
         Bushfire (December 2019) (referenced herein as SPP (Bushfire) 2019); and
    •    Queensland Fire and Emergency Services. (2019). Planning for Bushfire Resilient
         Communities.

4.2 Asset Protection Zones
4.2.1    General
Asset Protection Zones (APZ) provide a defensive tool to assist in the reduction of potential bushfire
impact to people and property situated in bushfire prone areas. For illustrative purposes, Plate 9
depicts the concept of an APZ surrounding a dwelling in a bushfire prone areas.




                                             Plate 9 – Asset Protection Zones

The development has been confirmed to be located within a bushfire hazard area hence provision
of adequate separation between the proposed works and the hazardous vegetation located on all
sides is required to provide a reasonable level of safety to site occupants and emergency services
staff.
The configuration of APZ’s is typically determined based on the results of the site-specific hazard
assessment including risk of bushfire impact, flame length analysis, potential AS3959-2018 Bushfire
Attack Levels and SPP Bushfire 2019 Assessment Benchmark setback requirements (Refer section
4.2.3)

4.2.2    State Planning Policy – State Interest Guidance Material (Natural Hazards, Risks and
         Resilience – Bushfire) December 2019
Assessment Benchmark 4 of the State Planning Policy – state interest guidance material references
benchmark separations for new developments however for consistency, can be used to ascertain
suitable separations for new buildings on existing lots.
Assessment Benchmark 4 states:
Development supports, and does not hinder, disaster management response or recovery capacity
or capabilities. Where reconfiguring a lot creating lots of greater (or less) than 2000 square metres:
To ensure emergency access and operational space for firefighters the subdivision layout results in

Bushfire Management Plan v1                                                                NCES REF: J000953
Lot 189 on MCH1261 – 64 Reserve St, Pomona




lots that are sited so that they are separated from the closest edge to the adjacent medium, high or
very high potential bushfire intensity area by a distance that achieves a radiant heat flux level of 29
kilowatt per square metre or less at:
1. The building envelope, if identified at RaL stage, or
2. Where a building envelope is not identified, at all the lot boundaries.
Compliance with Assessment Benchmark 4 can be attained where the proposed building envelope
is sufficiently separated from the nearby forest hazard so that a radiant heat flux level at any point
on the building envelope, does not exceed 29 kW/m². In this instance a specific building footprint is
proposed hence the limit of the building footprint can be used in lieu of a building envelope.
4.2.3    Radiant Heat Flux Setbacks (APZ)
Determination of the setbacks required to satisfy Assessment Benchmark 4 can be identified from
the quantitative modelling output presented in Section 3.2 herein. The output results from Plate 8 &
9 can be used to identify the setback requirements to achieve the <29 kW/m² radiant heat flux SPP
requirement. The required setbacks are shown in Table 4.
                    Table 4 – Radiant Heat Flux Minimum Setbacks to secure <29kW/m²
                           VHC                     Direction          <29 kW/m² Setback*
                                                                             (m)
                                                 and slope (º)

* Source – Flamesol Minimum Distance Calculator Plate 8 & 9

Table 4 identifies a minimum setback of 17.9m to the north, south, and east and 11.7m to the west
is required to expose the building to <29 kW/m² radiant heat flux.
It is therefore recommended the proposed works are provided with a minimum 17.9m setback to the
VHC 8.1 vegetation to the north, south and east, and a minimum 11.7m setback to the VHC 9.1 to
the west to achieve an acceptable level of risk under the SPP. The extent of the recommended APZ
is detailed in plan BAL02 – Separation Requirements.

Lot 189 on MCH1261 – 64 Reserve St, Pomona




4.3 Water Supply
The availability of a reliable water supply for firefighting purposes is a vital tool in the defence of
bushfire impact. Reticulated water supply is currently not available within the site. The proposed
development will therefore require provision of a readily accessible on-site emergency static water
supply in accordance with Assessment Benchmark 4 of the SPP Bushfire 2019. Assessment
Benchmark 4 references the QFES 2019 Bushfire resilient communities document for information
regarding appropriate static water supply. Section 9.1 of Bushfire resilient communities’ states:
An appropriate static water supply (in bushfire prone areas where reticulated supply is not provided)
to support effective emergency services response includes a water tank that is available solely for
firefighting purposes and can be accessed by firefighting appliances. The water tank is to be provided
within 10 metres of each building (other than a class 10 building), which:
a) is either below ground level or of non-flammable construction;
b) has a take-off connection at a level that allows the following dedicated, static water supply to be
left available for access by firefighters:
i.10,000 litres for residential buildings;
It is therefore recommended that a dedicated 10,000 litres should be made available to the proposed
new dwelling.
Note that the above recommended water supply volumes should be a static water supply. The
volume should be reserved for fire fighting purposes only. Plate 10 outlines an example of how this
can be achieved.




Plate 10 – Example Static Water Supply tank design for fire fighting purposes (Source: Kingspan Group 2021)

4.4 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.
It is recommended a trafficable fire trail is provided around the inner perimeter of the recommended
APZ and which connects to the driveway to allow for safe access and egress and operational space
for fire-fighting vehicles.

4.5 Vehicular Access
Development in bushfire prone areas should be serviced by safe access/exit points for both
occupants and emergency services personnel. The development is to be serviced by a single access
driveway connecting to Reserve Street to the west. The total length of the proposed road is
approximately 100m and will generally be constructed on flat ground. The proposed driveway will be

Page 17

Bushfire Management Plan v1                                                            NCES REF: J000953
Lot 189 on MCH1261 – 64 Reserve St, Pomona




located adjacent to Reserve Street and the cleared powerline easement, therefore the risk of
access/egress becoming constrained during a bushfire event is deemed low.
It is recommended the driveway is built to a minimum of 3.5m width in accordance the QLD Fire
Hydrant and Vehicle Access Guidelines 2019 and a passing bay be provided about the halfway mark
of the driveway. No further driveway recommendations are deemed necessary.

4.6 Landscaping and Regrowth
Existing and future landscaping within the site should avoid increasing the potential for bushfire
hazard. Assessment benchmark 5 of the SPP Bushfire 2019 seeks that the site layout places the
landscape and open spaces within the site between premises and adjacent mapped medium, high
or very high potential bushfire intensity areas. This landscaping and open space comprises
protective landscape treatments that:
1. Comprise only low threat vegetation (for example grassland managed in a minimal fuel condition,
maintained lawns, golf courses and cultivated gardens); or
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.
To reduce the potential for bushfire impact to buildings, structures and occupants as a result of future
regrowth and landscaping works within the site, it is recommended:
    •    The vegetative conditions within the nominated APZ satisfies Assessment Benchmark 5 of
         the SPP Bushfire 2019, including the low threat vegetation criteria prescribed in section
         2.2.3.2 of AS 3959:2018 or later iterations thereof. This generally entails:
             o   Removal of surface and near surface fuels (i.e., leafs and twigs and branches) and
                 understorey shrubs and replacement with lawn, dirt or gravel or a combination
                 thereof. Retention or installation of discrete clumpings of surface and understorey
                 fuels/plants is acceptable as long as they do not offer continuous fuels load pathways
                 from the forest to the building.
             o   Low hanging canopy and mid canopy foliage should also be removed to
                 approximately 3-4m height above ground level and no limbs are to extend to within
                 6m of the roof line of the buildings. All pruning should be undertaken in accordance
                 with AS 4373 Pruning of amenity trees. Note large trees do not need to be removed
                 however we recommend no trees or shrubs are retained within 10m of the building
                 for safety purposes and to separate potential crown fire from structures;
    •    No woody mulch is used within 2m of buildings;
    •    Future landscaping works/plantings maximise the use of locally indigenous, low flammability
         species and or low-density plantings of suitable open forest /woodland species with low bark
         shedding characteristics. Landholders should consult their local native plant nursery for
         suitable species selection.
The recommended APZ is required to be maintained by the individual landholder/s and or occupants
and is to consist of low threat conditions in perpetuity.

4.7 General Property Maintenance
The undertaking of an appropriate level of property maintenance throughout the year, and in
particular prior to the fire season, can significantly reduce the severity of fire impact upon a site.
Queensland Fire and Emergency Services recommend the following general actions be undertaken
to prepare for the fire season:
Structure
    •    Clear leaves, twigs, bark and other debris from the roof and gutters.
    •    Purchase and test the effectiveness of gutter plugs.
    •    Enclose open areas under decks and floors.

Lot 189 on MCH1261 – 64 Reserve St, Pomona




    •    Install fine steel wire mesh screens on all windows, doors, vents and weep holes.
    •    Point LPG cylinder relief valves away from the house.
    •    Conduct maintenance checks on pumps, generators and water systems.
    •    Seal all gaps in external roof and wall cladding.
Access
    •    Display a prominent house or lot number, in case it is required in an emergency.
    •    Ensure there is adequate access to your property for fire trucks - 4 metres wide by 4 metres
         high, with a turn-around area.
Vegetation
    •    Reduce vegetation loads along the access path.
    •    Mow your grass regularly.
    •    Remove excess ground fuels and combustible material (long dry grass, dead leaves and
         branches).
    •    Trim low-lying branches two metres from the ground surrounding your home.
Note the above recommendations are that of QFES and are offered herein for advisory purposes.
They have not been set as recommendations for certification purposes.

5    AUSTRALIAN STANDARD 3959:2018 CONSTRUCTION OF BUILDINGS IN
     BUSHFIRE PRONE AREAS (AS 3959:2018) SETBACKS

The Bushfire Intensity Overlay Map on the State Planning Policy (SPP) Interactive Mapping System
identifies that the entire site is affected by a High Potential Bushfire Intensity Area and a Potential
Impact Buffer (refer to Plate 1). The build site is therefore located in a designated bushfire prone
area hence the future proposed works must be constructed to satisfy AS 3959.
Building works within Designated Bushfire Prone Areas identified on a power of legislations Hazard
Overlay Map triggers building design assessment under AS 3959:2018. The Standard provides
minimum construction requirements for new habitable dwellings and habitable building alterations in
designated Bushfire Prone Areas. The construction requirements are intended to improve the
performance of buildings subjected to burning debris, radiant heat or flame contact. Building works
in Designated Bushfire Prone Areas must be built to the Bushfire Attack Level (BAL) construction
standard relevant to the building site as identified by the AS 3959:2018 methodology.
A specific BAL assessment has been conducted (NCES 2021) for the proposed development within
the site. The recommended APZ will result is a BAL 29 outcome for the proposed new dwelling
(Refer Section 4.2.3 of this report and BAL02).

6    CONCLUSIONS

This Bushfire Management Plan has been prepared to assess and manage the degree of
potential bushfire risk acting on the proposed new dwelling for Lot 189 on MCH1261, located
at 64 Reserve Street, Pomona.
A bushfire risk assessment has identified that the vegetation about the site exposes the
proposed dwelling to significant risk of ember, radiant heat and direct flame impact in the
absence of additional clearing being provided. The identified risk has been reduced to an
acceptable-tolerable level where all recommendations set herein are adopted (i.e. APZ’s).
Overall, the development proposed for the site, in combination with recommendations
referenced herein, is deemed suitable with respect to providing a reasonable level of
protection for people and property within the site.
Bushfire is an extremely serious and often unpredictable phenomenon that requires serious
preparatory planning and decision making to avoid potential damage to infrastructure and or
loss of life. All recommendations made herein have been formulated based on site conditions
at the time of writing and therefore may not be appropriate in the event site conditions change
over time.
Implementation of the bushfire mitigation measures referenced herein is not implied nor
intended to advocate that residents remain on the site during a bushfire event nor that people
and property will be protected from bushfire impact. The measures are intended to reduce
the potential severity of bushfire impact to persons and property and not prevent actual
bushfire impact.
The landowners and site managers are to be responsible for ensuring the measures
prescribed herein are applied and stay up to date with site conditions and industry standards.
Landholders/managers should therefore liaise with Queensland Fire and Rescue Services at
regular intervals (e.g. recommended at least every 5 years).
The first call in the event of a bushfire emergency should always be ‘000’.
