2.1 General
The site comprises an irregular shaped allotment located to the south of the Pomona town centre
and has area of approximately 3.6ha. Existing low density residential allotments exist along Triller
Court to the east, with Tuchekoi National Park adjoining the site’s north-western boundary.
Vegetated rural properties adjoin the site’s southern boundary.

2.2 Topography
The slope of the land is a major determinant of fire behaviour, particularly the slope of the land under
vegetation that contributes to bushfire hazard. Fire burns faster as it travels up slope, via preheating
of unburnt fuels ahead of the fire, increasing the rate of spread and fireline intensity. Conversely,
fires move more slowly as they travel downslope. Fireline intensity (kW/m) is a function of the rate
of spread (QFES 2019).
The site is located on sloping undulating terrain with slopes of approximately 5 degrees. A broad
ridgeline runs through the site on a roughly north-east to south west alignment. Slopes descend from
the ridgeline in a northerly and southerly direction. The site reaches a topographic high of
approximately 124m AHD in the south-west corner and declines towards the north-east to a
topographic low of approximately 93m AHD.
