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.

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


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.
