Flood Mitigation Investigation: Ashgrove Drive, Cooroy
Existing scenario Cooroy Creek flooding characteristics through the study area are shown in
Appendix A. Results are presented for the following design flood events:
10% Annual Exceedance Probability (AEP) design flood. A flood of this magnitude has a
1 in 10 chance of occurring every year.
1% AEP design flood. A flood of this magnitude has a 1 in 100 chance of occurring every
year.
0.05% AEP design flood. A flood of this magnitude has a 1 in 2000 chance of occurring
every year.
Results show that under existing conditions, major floods overtop the Bruce highway to the east of
Cooroy Creek and are directed straight towards the Ashgrove Drive Estate.
