      BUSHFIRE CONSTRUCTION REQUIREMENTS
32.   The dwelling is located on a property that is affected by a bushfire hazard overlay, and is therefore required to
      be provided with on-site water storage of at least 5,000 litres. This water may be stored within the domestic
      tanks, but the 5,000 litres must be reserved exclusively for fire fighting. The existing rainwater tank provided
      to the shed can also be used for this purpose.
33.   The allotment is located in an area that has been designated as a Bushfire Prone Area, by the local authority.
      An assessment against AS3959 has determined that a Bushfire Attack Level of 12.5 applies.
      The building must incorporate construction methods applicable to this BAL as detailed in AS3959. A
      certificate from the builder (or other suitable competent person) must be provided at the completion of the
      works certifying compliance with these requirements.
      The owner of the property must ensure that the assessment criteria used to determine the BAL are maintained
      throughout the life of the building. This includes maintaining the minimum separation distance and undertaking
      appropriate maintenance of any asset protection zone.
