         Does the new fencing need to be designed to collapse during flood events;

Based on the results obtained in the FIA, those sections of fence that are impacted by flood waters will not
need to be designed to collapse. The affected sections of fence line are located in floodwater that is slow
moving (< 0.2 m/s) and less than 1 m deep. They are also aligned with the direction of flow. It should be
noted that the fence line is located adjacent to dense bush land and downstream of a culvert crossing, both
of which will capture large debris before it can impact the fence. Any overland flow from the development
is expected to pass through the fence with minimal obstruction. This will be confirmed at the detailed design
stage.

         New development areas within or adjacent to the flood extents

There are no new development areas apart from the addition of the fence as outlined above.

         Runoff from the proposed development.

Runoff from the new layout will be less than previously as two villas have been removed, decreasing the
impervious area.
