2    Site Description

2.1 General
The site measures 2.997ha and is contained on the edge of the built residential area of the
Pomona township. Residential allotments adjoin the eastern site extent, with the Pomona
showgrounds located to the south of the site. Predominantly cleared rural grazing properties are
located to the north of the site, and a semi-vegetated rural allotment containing the Cooroora
Creek riparian corridor is located to the west of the site.
The eastern extent of the site contains established fruit tree orchards, with low density mature
trees present within the centre of the site. The western site extent is characterised by
predominantly mowed pasture with very few trees.
The site is zoned as Low Density Residential in the eastern extent and Rural zone in the western
extent under the Noosa Plan 2020.
Plate 3 depicts the site’s position in the landscape and the extent of existing development.

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 western extent of the site is relatively flat, with a gentle west facing slope present in the
eastern site extent. The site reaches a topographic high of approximately 100m AHD on the
eastern boundary and declines towards the west of the site to a topographic low of approximately
83m AHD. The eastern extent of the site exhibits slopes of approximately 8 degrees. Plate 4
depicts topography conditions within and adjacent to the site.
