The proposed dwelling, in the absence of further vegetation clearing approval, is assumed to be
seperated by a maximum of 10m to Type A Open Forest classified vegetation in all directions.
10m exempt clearing is afforded to dwellings on Category 3 Lots (>2ha not in protected vegetation
overlay area) and Category 4 Lots (>2ha and <10ha in protected vegetation overlay area) under
the defintion of Exempt Clearing (Clause (g)) in the Noosa Plan 2020. The Lot is assumed to be
a Category 3 lot. Therefore, in accordance with Table 4 the dwelling is exposed to BAL FZ.
An application for additional vegetation clearing can be made to NSC to increase the separation
distance hence lower the resultant BAL acting on the building. The extent of proposed vegetation
clearing should be identified on the proposed building plans. Generally, NSC is amenable to
approving vegetation clearing to secure no less than BAL 29.

5.3 Vegetation Management
The vegetation between the dwelling and the adjacent edge of the hazardous vegetation must be
maintained as low threat vegetation in order for the BAL ratings to be valid and to maintain these
BAL ratings into the future.
Vegetation conditions within the setbacks attributable to each BAL must comprise low threat
vegetation as per the definition prescribed in the Standard in order for the BAL construction
standards to be effective as intended. Clause 2.2.3.2 (f) of the Standard defines Low threat
vegetation as:
