Dear Peter,
Re: Bushfire Hazard Statement – Carramar Care, 186 Cooroy Noosa Road,
Tewantin
Rob Friend & Associates Pty Ltd has been asked to undertake an assessment of the bushfire hazard issues
relative to the proposed development application for the above site.
A site inspection was undertaken on the 15 June 2017 to ascertain the validity of the bushfire hazard mapping
over the property and adjacent properties as mapped in the Noosa Plan Natural Hazard Overlay Code (16
September 2013).
Development proposal
Carramar Care is proposing to lodge a Material Change of Use (MCU) application with Noosa Council to allow for
construction/expansion of a Dementia unit at the current facility at 186 Cooroy Noosa Road, Tewantin. The
development is proposing the construction of a further 7 buildings, consisting of 6 villas with 8 resident rooms per
villa, and an Entry Building which will contain a café as well as dining and resident facilities in the eastern portion
of the development footprint (see Figure 1).
We note, the current, proposed layout plan considers a setback of 14.1 metres as recommended and all
proposed structures allow for this setback. We note the asset protection zone (i.e. the 14.1 metre managed area
to achieve a Radiant heat flux of 19kW/m2), coincides with the eastern boundary of the site in the northern
portion and as its traverses the area it heads to the south-east until it meets the current wire fence identified by
the line in Figure 1 below.
The subject site currently consists of trees and regrowth vegetation (see Photographic Plate 2); however most of
this will be cleared for the development. A small portion of the existing vegetation will be retained, mostly a small
patch to the south of the existing Cartwright South building.

Site description
The subject site is located at 186 Cooroy Noosa Road, Tewantin and is described as Lot 2 on
RP177554, covering an area of 4.047 hectares (see Figures 2).
The site is zoned as Community Services under the Noosa Plan Zones.
The subject site is approximately 0.80 hectares in area and is west of the existing Dementia unit, which
was completed sometime in 2013.
To the north of the subject site are residential properties (see Photographic Plate 3), and the southern
boundary of the site is bordered by Cooroy Noosa Road. Across the Cooroy Noosa Road and further to
the south of the site is Tewantin National Park – Wooroi Day Use Area (see Photographic Plate 1),
Page 3
[3]
which includes a maintained, powerline easement and several internal, recreational tracks (see
Photographic Plate 5). We note the vegetation of the Wooroi Day Use Area close to the road and
powerline easement has been burnt within the last 3 years (see Photographic Plate 6).
East of subject site consists of a vegetated, waterway corridor, Lomandra Place Bushland Reserve (see
Photographic Plate 4), which contains a degraded woodland canopy of Paperbark teatree, Melaleuca
quinquenervia Swamp box, Lophostemon suaveolens and Black sheoak, Allocasuarina littoralis with an
understorey dominated by a range of environmental weed species such as Umbrella tree, Schefflera
actinophylla, Singapore daisy, Sphagneticola trilobata in the eastern and central portions.
In addition, Lomandra Place Bushland Reserve also contains a waterhole which occupies a significant
portion of the width of the park toward the western end of the Park.
We did note the western portions of the Lomandra Place Bushland Reserve and the area within the
subject site appear to have less disturbance from environmental weeds and contains more an
understorey and groundcover consistent with coastal paperbark wetlands.
We also noted, Lomandra Park nor the vegetated portion of the Carramar Noosa site is not mapped as
remnant vegetation. Furthermore, the area is also not mapped as remnant in the latest version 10
Regional ecosystem mapping over South-east Queensland or Bioregion 12.

Figure 2 – Aerial image
The Noosa Plan (2013)
The Noosa Plan (2013) Natural hazards overlay map does not map any areas within the subject site nor
the adjacent Lomandra Place Bushland Reserve as being a Bushfire hazard area. we note under the
State Planning Policy – Natural Hazards, Risk and Resilience – Technical Manual corridors of
vegetation less than 100 metres can be mapped in accordance with the dominant adjacent bushfire
hazard class and as the adjacent areas are mapped as Low bushfire hazard, the waterway corridor is
also mapped as an area of Low bushfire hazard.
The Noosa Plan does however map the vegetation in the Tewantin National Park to the south of the site
and a small portion to the south east of the site as Very high potential bushfire Intensity (see Figure 3).
As a consequence, the 100-metre-wide Potential impact buffer extends over more than half of the
southern portion of the site.
As the site is affected by area mapped as Very high potential bushfire hazard and the Potential impact
buffer, a response to the Natural Hazards Overlay Code is required (see Attachment I below).
Page 4
[4]
The Noosa Plan also maps this area as an Environmental Protection Area under the Biodiversity
overlay.
Figure 3 – Noosa Plan - Bushfire Overlay Map
Bushfire Hazard Assessment
Methodology
An assessment of the bushfire hazard was undertaken using a desktop review. Resources such as
historic and current aerial photography, Google street view images, the Noosa Plan (2013) and the
State Planning Policy (April 2016) Natural Hazards, Risks and Resilience Bushfire Hazard Mapping
were used as part of the desktop analysis.
A site inspection was undertaken to identify the status of vegetation within and around the site and to
determine the likelihood of a bushfire on the site presenting risk to life and property.
Findings
With respect to the existing vegetation on the subject site and to the east of the subject site, we
observed the following: -
Melaleuca quinquenervia, Eucalyptus microcorys, Eucalyptus robusta, Syncarpia glomulifera,
Cinnamomum camphora (w), Lophostemon suaveolens, Livistona australis, Syzygium smithii,
Endiandra sieberi, Acacia maidenii, Macaranga tanarius, Alphitonia excelsa, Allocasuarina littoralis,
Elaeocarpus reticulatus, Melaleuca linariifolia, Syagrus romanzoffiana (w), Glochidion ferdinandi,
Cryptocarya longifolia, Schefflera actinophylla (w), Senna pendula var. glabrata (w), Breynia
oblongifolia, Hovea longifolia, Lantana camara (w), Cordyline rubra, Lophostemon polygalifolia,
Nephrolepis cordifolia (w), Gleichenia dicarpa, Stephania japonica, Zieria sp. Smilax australis,
Gahnia sieberiana, Blechnum indicum, and Sphagneticola trilobata (w).
The eastern portion of the waterway corridor is entirely invaded by Sphagneticola trilobata across
the width of the waterway (see Photographic Plate 7). This will have a significant effect on the
ability of any fire commencing within the waterway corridor/Reserve
Page 5
[5]
With respect to the areas mapped as potential bushfire hazard in the Noosa Plan Natural Hazards
Overlay Mapping we make the following comments: -
We confirm the vegetation of the Tewantin National Park is correctly mapped as Very High potential
bushfire intensity based on the mapped Vegetation hazard class (8.1 – Wet eucalypt tall open
forest) and the FFDI over the area (FFDI – 47). However, we do note the bushfire hazards within
this section of the Tewantin National Park are managed by way of controlled burns and as such the
actual bushfire hazard presented by the understorey is significantly lees than the Potential bushfire
hazard level derived from the State based bushfire hazard data.
The subject site is separated from the Tewantin National Park by a distance of approximately 50+
metres due to the Cooroy Noosa Road and area on the road shoulder, and a bikeway which are also
maintained in a relatively clear state (see Photographic Plate 1).
Lomandra Place Bushland Reserve is less than 100 metres in width and can be deemed to be
considered the same bushfire hazard as the surrounding properties, as per State Planning Policy –
Natural hazards, Risk and Resilience – Technical manual. The Lomandra Place Bushland Reserve is
surrounded by areas of Low bushfire hazard.
Access into and away from the proposed facility will be provided by the Cooroy Noosa Road which has
two-way access allowing staff, residents and emergency services to approach the site from the direction
of Tewantin or Cooroy.
Additionally, the proposed dementia facility will also utilise the existing internal vehicle access routes
which will provide vehicle and Emergency Service access to the northern boundary as well as the
southern boundary. In additional Emergency vehicle access will also be available to each residential
villa via the proposed internal pedestrian tracks. It is acknowledged however that should the facility be
involved in a structural fire, Emergency Service may park close to a hydrant stand pipe and undertaken
fire suppression operations via extend hoses.
With regard to a vegetation fire, again the internal roadways and access tracks will facilitate rapid access
throughout the facility to protect buildings and if required, directly attack the fire when it is in proximity to
the facility.
With respect to potential evacuation, there are ample resident community space available within the
existing facility that can be used as a temporary evacuation area and where residents can be care for
until they are able to return to their respective rooms once emergency service give the all clear to do so.
Discussion
Bushfire hazard mapping
Further to our findings above and based on the vegetation types and therefore the Vegetation hazard classes as
described by Leonard et al (2014)1 we have come to the view that: -
With respect to the vegetation of Tewantin National Park to the south of the site it presents as a bushfire
hazard:
o We acknowledge the State Government’s Regulated Vegetation Management Mapping maps
the National Park as Regional ecosystem 12.5.6c - Eucalyptus pilularis open forest +/- E.
siderophloia, E. propinqua, Corymbia intermedia, E. microcorys, E. acmenoides, E.
tereticornis, E. biturbinata, Lophostemon confertus with E. saligna, E. montivaga at higher
altitudes. Occurs on remnant Tertiary surfaces. Usually deep red soils. (BVG1M: 8b).
o We generally agree with the State’s mapping with regard to the regional ecosystem throughout
this section of Tewantin National Park, however the area adjacent to the subject site is more
open and contains a relatively depauperata understorey and groundcover, and as such, is
better described as a moist to dry eucalypt forest on coastal lowlands and ranges i.e. VHC 9.1.
This area contains largely low to moderately flammable vegetation (see Photographic Plate 6)
1 Ibid.
Page 6
[6]
o Table 1 below provides the derived Potential bushfire intensity level using the methodology
after Leonard et al (2014)2 and as contained in the State Planning Policy – Natural Hazards,
Risks and Resilience – Technical Manual – A fit for Purpose approach in undertaking natural
hazard studies and risk assessment (April 2016)

1 – the VHC 9.1-Moist to dry eucalypt open forests on coastal lowlands and ranges was used as it is
representative of RE 12.5.6c and what we observed.
2 – the Potential fuel load is attributed with a potential fuel load by the State Government as part of the Leonard et.
al. (2014) methodology.
3 – the FFDI for the area is determined by the State Government as part of the Leonard et. al. (2014)
methodology.
With respect to the vegetation of the subject site and waterway corridor to the east of the site, it is
evident that it presents as a Low Bushfire Prone Area largely because of its width:
o The site inspection revealed there was an extensive invasion Sphagneticola trilobata in the
north eastern portion and a dam in the centre of the waterway corridor
o We note that a large amount of vegetation within the subject site will be cleared as a natural
consequence of the development, however an area in the south-eastern corner of the property
and contagious with the vegetation within Lomandra Park will be retained.
o Table 2 below provides an assessment of the status of the bushfire hazard without any
management input and as if the area was a Melaleuca open forest/woodland with all the
structural elements and characteristics of that forest. However, in accordance with Leonard et
al (2014) section 2.2.1 – Patch and Corridors,3 the waterway corridor and retained portion of
vegetation in the south of the subject site will be less than 100 metres in width and as such
using the State Planning Policy methodology this can be effectively described as low bushfire
hazard like the surrounding properties.

We also acknowledge that while the Lomandra Place Bushland Reserve is an area of low bushfire
hazard, it may become involved in a bushfire event and as such needs to achieve a separation from that
vegetation necessary to achieve the radiant heat flux of 19kW/m2.
Table 3 provides the outputs for potential setbacks from the retained vegetation. We acknowledge the
age and vulnerability of the residents using the proposed development and recommend that the setback
should achieve a lower radiant heat level than necessary for the residents.

Emergency Management plan
Noosa Care – Carramar has two Emergency Response documents which informs and guide the management’s
response in the advent of an emergency within and around the Carrama Care facility and which includes a
bushfire event. These documents are: -
1. Natural Disaster Response Plan (Carramar/Kabara WHS Coordinator, June 2016), and
Page 8
[8]
2. Fire and Evacuation Plan. This document has been prepared in association with the Qld Fire and
Emergency Service (renewed August 2012).
Both documents provide a process by way of a checklist if and when a natural hazard or disaster events occurs
that may threaten the Carramar Care Facility. I the advent of a bushfire event the specified actions include: -
Identifying the natural disaster threat and confirming the threat with local Emergency service personnel
such as Police, QFES or State Emergency Service local coordinator.
Switch of air-conditioning units to units and depending on the resident, keep them in their unit and
monitor their state of wellbeing or move then to a central location where they can be cared for and
monitored by staff which includes a Registered Nurse.
If staff become aware of an impending threat to the facility and within time to relocate residents to
another facility for a short term, then staff and residents will be relocated. The Police will be notified if
this is an action which the facility will initiate.
Conclusion
Based on the above findings and discussions it is our opinion that: -
1. The bushfire hazard mapping of the Tewantin National Park can effectively be mapped as an area of
medium bushfire hazard based on the particular vegetation assemblage within the area adjacent to the
subject site.
2. A 100-metre-wide Potential impact buffer still extends over more than half of the subject site.
3. Although the waterway corridor and the retained vegetation on the site are considered an area of Low
bushfire hazard in accordance with the Patch and Corridor mapping methodology as per section 2.2.1,
Leonard et al (2014),4 given the age and vulnerability of the residents using the proposed development
the bushfire hazard planning for this vegetation will need to consider these aspects.
4. Appropriate bushfire mitigation infrastructure such as a managed setback area can be integrated into
the development to provide effective bushfire protection and mitigation for the development, despite to
determination that the adjacent area is considered to be an area of Low bushfire hazard using the
latest bushfire hazard mapping methodology
5. The Carramar Care Facility has two Emergency Response documents that are relevant to the facility
and which will inform the emergency response should a bushfire event potentially or actually threaten
the facility. Our review of these documents indicate that they are acceptable for providing a response
to a bushfire event within the local area.

Recommendations
The following recommendations have been made with respect to mitigating against the external bushfire hazards
as part of this development:
1. All buildings to be set back from retained vegetation by at least 14.1 metres to ensure the maximum
exposure to a bushfire event is 19kW.m2 as determined using Method 2 in AS3959-2009 (see Figure
1).
2. All buildings to be constructed to a minimum BAL-19 standard as provided by the Australian Standard
AS3959-2009.
3. The understorey within the 14.1 metre setback be removed and maintained as groundcover less than
200 mm in height.
4. All trees which have branches that extend closer than 5 metres to any structure be trimmed or if an
Arborist is of a view the trimming would destabilise the tree then it be removed.
5. Retained vegetation required to be maintained by regular maintenance particularly prior to the bushfire
season in South-east Queensland, September to December.
6. Vehicular access to be provided around buildings to enable access for Emergency Services.
7. The facility be connected to reticulated water and a hydrant standpipe be located in the northern and
central parts of the proposed development area to allow rapid access to reticulated water by
Emergency services for structural and vegetation fires.
