Cooroy Hinterland Park Flood Assessment



7 CONCLUSION
Hydrology and Water Management Consulting (HWMC) has completed this flood assessment for
the proposed Cooroy Hinterland Park on behalf of Noosa Council.

Cooroy Creek flooding is the dominant source of flooding at the site and modelling has
demonstrated that care is required to ensure that the design of the park will not increases flood
risk on surrounding properties. Modelling has been used to develop several mitigation measures
that have successfully reduced offsite flood impacts to an acceptable level. The results of this
assessment should inform future design of the park and it is recommended that the final park
design configuration be subject to a further assessment to ensure positive flood outcomes are
achieved.

Further consideration on possible treatment strategies of local stormwater runoff through the site
is recommended if the drains are to remain open and accessible to users of the park.

Recommendations have been made in relation to managing safety and maintenance risks
associated with construction of a park on a site with a low level of flood immunity.
