“Utilisation of the Rational Method, as described within the Manual, may be considered
appropriate…as a ‘checking tool’ (not calibration) of numerical models developed for small ungauged
catchments (i.e. checking for potential gross errors)”.
It appears the ARR1987 methods and IFD data have been applied, however, this is not explicitly stated
in the report.
There are several cross references that point to information that does not appear relevant to the text.
One example is that Section 4.3.2 indicates that Appendix A contains illustration of modelled
catchments but Appendix A does not contain catchment plans.
Regional flooding, minimum floor levels and access during flood events has not been mentioned.
The SWMP indicates water captures for detention purposes. The planning scheme also seeks that
development captures water for re-use for non-potable purposes.

Information Required

13. Update the Stormwater Quantity Management section of the report to clarify methods, reference
    current guidelines and statutory documents, correct cross references and address regional
    flooding, minimum floor levels and access to the proposed aged care facility during flood events.

14. Amend the SWMP to include the capture and re-use of water for non-potable purposes.

Response
Refer attached amended Stormwater Managements Plan prepared by Empire Engineering.
