No significant vegetation is located on the land that is required to be removed to facilitate
development.

The land is partly located within an overland flow path which predominately maintains a low flow
volume but is affected by localised stormwater flows during a 1% AEP event. The extent of localised
flooding across the land, as well as the velocity and duration of flow has been considered by the
hydraulic expert. In order to facilitate a resolution of the Appeal, the Appellant instructed its consultant
to prepare further options above those set out on the First joint Expert Report of the flooding experts,
dated 2 August 2019 which propose works on site to minimise the risk from flooding.

One of the options put forward (Option 1) (Attachment 4) has been accepted by the Council (refer
Attachment 7). The advice from the hydraulic expert has also considered the flooding impact caused
by the proposed development on adjoining residential properties. Importantly, the flooding impacts
relate to the proposed development only, with the dwelling, the extension and access ways already
existing on the land.

The extension to the dwelling complies with acceptable solutions with respect to Flooding, drainage
and earthworks (S2.1 and 2.3) under the Building Works Code. Consequently, the matter of flooding
is only relevant to the application being considered, which is for reconfiguring a lot and a material
