Figure 46 – Catchment boundaries




 Source: Cardno

The larger external catchments to the north and north west follow the existing flow paths where
available and the proposed flow path as detailed further in Section 7.4.3 of the revised report.

The smaller catchments directly west of the proposed development have been included in the
detention storage modelling with the assumption that flows from these smaller areas will be captured
by onsite drainage. It should be noted that Council has a drainage network already installed at these
locations. Modelling has been performed with this network removed as its effectiveness is unknown.


ISSUE 11: FLOOD MODELING
Further details of the flood modelling are required before an assessment of the suitability of the model
can be made.
Information Required
    42. Provide further details of the hydraulic model assumptions and a revised assessment as
        necessary to address the following:
            a. Clarify model grid size and provide a plan showing location of 1-D elements in existing
                and proposed scenarios
