Lot 2 on RP131369 – 108 Black Mountain Range Road, Black Mountain



2    Site Description

2.1 General
The site measures 5.98ha and is flanked by Black Mountain Range Road on the western
boundary. The site is located within a rural residential landscape characterised by residential
dwellings, vegetated areas, amenity plantings, areas of open pasture and hobby farms.
The eastern extent of the site and the north-west corner of the site are dominated by regrowth
vegetation. A residential dwelling and associated shed exist with the south-western corner of the
site, located within an area of maintained grass with scattered trees.
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 dominated by a predominantly east-west aligned broad ridgeline which traverses the
site resulting in mixed aspects and topography. Moderate slopes decline from the ridge line and
descend to ephemeral drainage lines contained within gullies. The site reaches a topographic
high of approximately 193 AHD on the western boundary and declines towards the south-east
corner of the site to a topographic low of approximately 145 AHD. The site exhibits variable slopes
of approximately 5-15 degrees.
