Disclaimer
Not withstanding the precautions adopted within this report, it should always be remembered that
bushfires burn under a wide range of conditions. An element of risk, no matter how small always
remains, and although the standard is designed to improve the performance of such buildings, there can
be no guarantee, because of the variable nature of bushfires, that any one building will withstand bushfire
attack on every occasion.

Executive Summary
This report provides an assessment of the Bushfire Attack Level (BAL) in accordance with
AS3959-2009 Construction of Buildings in Bushfire Prone Areas for Stage 31 within the
NorthLakes Estate.
This BAL report has shown that any future dwellings within the site will be able to meet the
requirements of both AS3959-2009 and the addendum to Appendix 3 of Planning PBP 2006
(NSW Rural Fire Service NSW) and will meet complying development under the Code SEPP.

1 INTRODUCTION
Firebird ecoSultants Pty Ltd has been engaged by North Lakes Pty Ltd to undertake a
Bushfire Attack Level (BAL) report for Stage 31 within the Northlakes Estate hereafter
referred to as the “site”. Refer to Appendix A for Sales Plan.
This BAL report assess the application of Australian Standard AS3959-2009
‘Construction of Buildings in Bushfire Prone Land’ and Appendix 3 of Planning for
Bushfire Protection 2006 (PBP, 2006). This report has been prepared to provide
guidance to prospective purchasers of what Bushfire Attack Levels (BALs) may be
required for future dwellings within the site.
1.1 Site Particulars
Locality: Stage 31 Northlakes Estate
LGA: Lake Macquarie City Council (LMCC)
Forest Danger Index: 100
Current Land Use: Approved subdivision
Bushfire Attack Levels – Stage 31 Northlakes Estate Page 2
2 METHODOLOGY
The Australian Standard for assessing the BAL and providing the detailed requirements
for construction has been reviewed and amended with the latest version being adopted
for use in bushfire prone areas of NSW in May 2010. This version is titled AS 3959-
2009 ‘Construction of Buildings in Bushfire Prone Areas’ (standards Australia 2009,
incorporating amendment 1 (November 2009) and amendment 2 (February 2011), with
amendment 2 being used in this assessment.
In addition, the NSW method of determining the bushfire attack level, found in
Appendix 3 of the document ‘Planning for Bushfire Protection 2006’ (NSW Rural Fire
Service 2006) has also been reviewed and amended to come into line with the process
within AS 3959. Therefore, in NSW the methodology with AS 3959 is to be used to
determine the bushfire attack level.
2.1 Vegetation Assessment
Vegetation surveys and vegetation mapping carried out on the site has been
undertaken as follows:
Aerial Photograph Interpretation to map vegetation cover and extent.
Confirmation of the vegetation assemblage typology present via a site
inspection.
2.2 Slope Assessment
Slope assessment has been undertaken as follows:
Aerial Photograph Interpretation in conjunction with analysis of electronic
contour maps with a contour interval of 10m.
On site confirmation of slope measurements.

3 SITE ASSESSMENT
The following assessment has been undertaken in accordance with the requirements of
PBP (RFS, 2006) and AS3959-2009. A site inspection was undertaken on the 10 April
2013.
3.1 Vegetation and Slope Assessment
An assessment of the slope affecting the bushfire behaviour was undertaken for a
distance of 100m from the edge of the lot boundaries in the direction of the bushfire
hazard. The slopes leading away from the site have been evaluated to identify both
the average slope and by identifying the maximum slope present. These values help
determine the level of gradient which will most significantly influence the fire behaviour
of the site. Refer to Table 3-1 for Vegetation and Slope Assessment.

4 BUSHFIRE ATTACK ASSESSMENT
4.1 Bushfire Attack Assessment
To determine the bush fire attack and required Bushfire Attack Level (BAL) for the
proposed subdivision the following steps were followed:
1. Determination of the vegetation types within 100m of the site, as assessed in
section 3 of this report.
2. Determination of the distance between the vegetation and future dwellings has
been assessed in section 4.2 of this report.
3. Determination of the effective slope as assessed in section 3 of this report.
4. A FDI of 100 was determined for LMCC LGA.
4.2 Determination of Bushfire Attack Levels
The results from the above steps were used to calculate the required BAL either using
Table 2.4.2 of AS3959-2009. The temporary APZs and permanent APZs have been
used in this assessment.
The results from this bush fire attack assessment are detailed below in Table 4-1–
Bushfire Attack Level (BAL) Assessment and Figure 4-1 Bushfire Attack Level Map.
