Flood Mitigation Investigation: Ashgrove Drive, Cooroy
3 EXISTING SITE TOPOGRAPHY AND FLOODING CHARACTERISTICS
The Ashgrove Drive estate is built across a small tributary of Cooroy Creek which also forms an
active flow path of the Cooroy Creek floodplain during times of flood. The location of the study
area is shown on Image 3-1 below which also shows surrounding topography (1m contours with
thematic mapping) and the path of the local tributary through the estate.
The current drainage easements and infrastructure at Ashgrove Drive are not sufficient to convey
Cooroy Creek flows and consequently floodwaters enter the surrounding residential properties.
