Report on Updated Bushfire Management Plan for            Stockwell Development Group Pty Ltd
Undeveloped Area of Noosa Civic


1. Introduction
The Noosa Civic site (total area 72.76ha) has enjoyed three completed stages of
development. This development has included commercial, industrial and residential
components. This has been largely in the north and west of the site. (see Aerial
Photograph No. 1)


The original Master Plan identified large areas of ecological significance which has been
quarantined by Council Park/Open Space or Environmental Covenant. (see Aerial
Photograph No. 1)


The next stages of development include the clearing of all the nodes of expansion. (see
Clearing Plan)


The entire area has enjoyed previous Bushfire Management Plans and this is an update of
these previous plans and bushfire assessments.




2. History
Prior to 2003 the site had been partially cleared and enjoyed a range of uses. In 2003 an
unplanned bushfire burnt the entire site. (Refer to Photographs in 2004 Bushfire
Management Plan) There has been no burning, planned or unplanned, on the site since
2003.


The development to date has effectively eliminated the bushfire hazard from the north and
west.

3. Description of the Site
There are (5) development nodes proposed in this application. (see Developable Area
Plan) The entire precinct is gently sloping towards Eenie Creek.


These areas have a range of exposures to bushfire risk as follows:-


Area 1
Small cleared area (0.34ha) with no bushfire implications.


Area 2
Small area (<2ha) with cleared transmission easement separating the adjoining National
Park.


This area, once cleared for development, has some minor risk from the east and north.


Area 3
Small area (0.8ha) mostly cleared and with no bushfire implications.


Area 4
Large area to be cleared except environmental covenant strip along Walter Hay Drive and
against the existing shopping centre.


There is exposure to hazard and risks to the south west and south from adjoining retained
Council Park.


Area 5
Small area (1.3ha) with minor exposure to retained watercourse covenant along narrow
eastern edge. There are no bushfire implications for this node.


Overall, the proposed development removes the existing risks associated with the
adjoining Noosa Civic Shopping Centre.

4. Bushfire Hazard and Risk Analysis
The State Planning Policy Bushfire Hazard Mapping (SPP) places the development area in
high and very high hazard. (see SPP Map)


Onsite inspection and assessment confirms the following:-
   1. With the development of the (5) nodes the only hazardous vegetation will be the
        small areas of environmental covenants. These are too small and linear to be
        considered a risk to the development or surrounds. (see Potential Hazard Map
        after Development)
   2. The Open Space/Park lands to the south of the development is high hazard and
        with considerable fuel loads. This land burnt in 2003 and will burn again unless the
        fuel loads are managed.
   3. The lands to the east are National Park and high hazard areas. These lands will
        burn from time to time. It is possible for some minor ember attack to reach the
        proposed development but this can be addressed under construction requirements.
        The presence of Walter Hay Drive is a major separation for most of the site from the
        eastern National Park. Area 2 has some exposure but enjoys the power line
        clearing and only a narrow and small area of National park to the north.


The proposed development includes the clearing of internal vegetation with the retention of
environment covenants. (see Clearing Plan)


The connection of Hofmann Drive to Walter Hay Drive improves access and provides
protection for the internal development north of Hofmann Drive.


Overall, the risk of a damaging bushfire threatening the nodes of development is restricted
to the external vegetation south and south west of the development. (see Aerial
Photograph No. 1)

5. Mitigating Actions for Compliance with Bushfire Overlay
5.1 Access
The link of Hofmann Drive to Walter Hay Drive provides a major improvement for
emergency access to the site.


5.2 Bushfire Buffers / Firebreaks
       Walter Hay Drive provides a substantial buffer from the National Park to the east.
       The power line buffer against Area 2 provides an adequate protection for this small
        unit.
       The power line clearing extends out to Eenie Creek Road and isolates the small
        area of National Park north of Area 2. It would be prudent for some fuel load
        management in this area depending on the style of development in this area.
       The zone adjoining the Council Park at Lots 12 – 15 requires a 20m buffer from
        development. This land will be cleared and will be used for car parks and access.
        No building can be constructed in this area. (see Bushfire Buffer Plan) The
        southernmost section of Lot 12 adjoins the environmental covenant area.


The immediate 20 metres in this environmental covenant will be managed with the
following actions:-
       All weeds will be removed.
       All understorey up to 6m in height will be removed and the ground fuels maintained
        at <8 tonnes/ha by physical means.
       This will be the responsibility of the owner of Lot 12.


5.3 Water
The entire estate will have reticulated water with appropriate fire hydrants.


Lots 12 – 15 will each have a fire hydrant with a hose and reel along the outer boundary of
each lot adjoining the park land.

Undeveloped Area of Noosa Civic


5.4 Vegetation Management
5.4.1 Internal
The fuel loads of the environmental covenants should be monitored and managed to <8
tonne/ha. This can be achieved by mechanical means or where attached to larger
adjoining park it may be achieved by hazard reduction burning.


5.4.2 External
       The patch of vegetation north of Area 2 in the National Park should be considered
        for a cooperative hazard reduction burn with National Parks. This would only be
        needed on a once in 10 year cycle.
       The entire Park area south to Eenie Creek should also have management that
        would include hazard reduction burning.



6. Compliance with Natural Hazards Overlay Code
    (13.28 of the Noosa Plan)
6.1 Overall Outcomes
       The previously approved development provided actions that had minimal ecological
        impact, allowed a safe environment for people and property and sufficient capacity
        for bushfire response if required.
       This final development will provide extensively improved bushfire safety for the
        existing developments and the new areas.


6.2 Specific Outcomes

                                         the entire development.
                                        Complies




7. Conclusion
The proposed extension of the previously approved development will materially improve
the bushfire safety for the entire precinct.


The SPP Hazard Mapping confirms the need for a set of mitigating actions to ensure the
safety of people and property.


The details in section four of this Bushfire Management Plan confirm the capacity to
comply with the current Noosa Plan Natural Hazards Overlay Code.
