Attachment B - Bushfire Management Plan

2.2.3 Potentially Hazardous Vegetation
Based on the above assessment, vegetation posing a High Potential Bushfire Hazard to the
proposed development is present to the northwest, and medium potential hazard vegetation
is present in all other directions. These vegetation communities have the potential to
accumulate high to moderate fuel loads and subsequently present a potential Bushfire Hazard
to the proposed development. It is noted however that the setback to potentially hazardous
vegetation to the immediate west, is considered to be >50m due to infrastructure, dams and
other associated fragmentation. N.B. Vegetation within the existing development footprint
has been classified as having a Low Potential Bushfire Hazard, due to its managed nature and
low fuel load potential, all-be-it within a Potential Impact Buffer area.

The following section details Bushfire Risk Mitigation measures to be implemented on the site
to address the Bushfire Hazard and compliance requirements acting on the proposed
development.

2.2.4 Potential Fire Runs
In Queensland, wildfires can occur at any time of the year, however the fire season usually
coincides with progressive drying following the autumn rain season, peaking during the spring
months of more severe fire weather, and concluding with the arrival of more regular storm
events and rain in late spring and summer. On the east coast, this peak fire season is
characterised by frequent dry northerly to westerly winds and lower humidity. Furthermore,
there is a low likelihood of a severe bushfire developing under south to easterly winds, which
generally facilitate high humidity, cooler land temperatures and periods of rainfall.
It is also important to assess the length of fire run to grasp an understanding of the scale of
fires that may be able to eventuate in a particular area. The length of fire run influences the
area in which a fire has to develop and reach its potential maximum intensity for the
conditions prevailing at the time of the fire. Fire runs less than 1km in length may be safely
regarded as having a lesser risk than longer fire runs.

Fire runs may be modified by natural features such as creeks, swampy wet areas, rock
formation or wet vegetation types depending on weather conditions and how dry the fuel is.
Fire runs may also be limited by roads, cleared/developed areas, firebreaks or active
intervention of fire suppression techniques such as lighting of backing fires from control lines.
Understanding Fire Runs is an important tool in managing Bushfire Hazard and potential
impacts to people and property in the event of a bushfire emergency.

Potential Fire Runs
Potential fire runs to proposed development in all directions have been considered.
The potential fire runs from the north through northwest are relatively limited. Although
connectivity is apparent for approximately 600m to the northwest, fire run in this direction is
limited by the township of Pomona to the north, and extensive clearing to the east and west.
