Bushfire Hazard Assessment & Management Plan v2                                        NCES REF: J001001
Lot 47 on RP860577 – 60 Glenridge Drive, Cooroibah



2    Site Description

2.1 General
The site covers 16.38ha and is flanked by Glenridge Drive along the north-eastern boundary and
McKinnon Drive along the western boundary. The majority of the site is characterised by cleared
farmland with isolated vegetation patches adjacent to the site’s perimeter and in the site’s northeast
about a drainage feature. Various permanent and non-permanent structures are present adjacent to
the site’s western boundary and a dwelling with associated infrastructure is present in the northeast
corner of the site.
The site is zoned as Rural Residential within the Noosa Plan 2020.

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 relatively flat terrain. The site reaches a topographic high of approximately
14m AHD along the site boundaries and declines to a topographic low of approximately 11m AHD
about the gully in the site’s northeast. Undulating slopes of 1-2 degrees are prevalent across the
site. A shallow farm drain leads into a 1st order stream in the northern portion of the site. The stream
then flanks the eastern site boundary (off-site) and then returns in a south westerly direction through
the south-east corner of the site.
