                     Figure 7 – Photograph taken of vegetation from Heritage Park

The applicant has undertaken a bushfire hazard reduction assessment as well as an onsite
vegetation assessment which resulted in a revised plan of development that included a building
envelope for any future dwelling on Lot 2 that complies with a separation distance equal to
29kW/m2 measured from hazardous vegetation associated with VHC 22.1 (Melaleuca open forest).
This results in a separation distance requirement of 14.2 metres measured from the eastern
boundary to the proposed building envelope. The 14.2 metre separation distance is completely
within private property. No future maintenance requirements will be imposed on Council, and it will
be the responsibility of the lot owner to maintain this area.
A nominated building envelope for Lot 1 has not been proposed in support of the development
application. To ensure that any future development on Lot 1 complies with a separation distance
equal to 29kW/m2 measured from hazardous vegetation conditions will be imposed for a revised
bushfire hazard assessment to be undertaken taking into account the fuel load from the south.
The site is connected to reticulated water and has access to fire hydrant located adjacent to No 9
Billabong Way.
The applicant has provided an emergency evacuation plan for both lots to manage the bushfire
risk in the event that a bushfire occurs in proximity of 11 Billabong Way, Tewantin.
Conditions of approval have been provided in line with this evacuation plan.
