Site assessment and site plan

The assessment of the subject lots was undertaken on 21 August 2018 for the purpose of determining the

Bushfire Attack Level (BAL) in accordance with Australian Standard AS 3959-2009 Construction of Buildings in

Bushfire Prone Areas (AS 3959-2009) Simplified Procedure (Method 1). An overview of the site is presented in

Figure 1.

Vegetation classification

All vegetation within 100 m of the subject lots was classified in accordance with Clause 2.2.3 of AS 3959-2009.

Each distinguishable vegetation class with the potential to determine the Bushfire Attack Level (BAL) is

identified below and presented in Figure 1. It is currently assumed that areas of landscaped vegetation will be

managed and maintained by Summit Homes Group (the developer) before being handed to the City of

Rockingham for maintenance.
