2.2.1.2 Defined Flood Levels and Flood Immunity
An assessment was completed to identify if the proposed buildings associated with the development will achieve the required 0.5m
freeboard. Table 2.5 provides a summary of the floor levels along with associated defined flood level, freeboard provided and if it achieves
the minimum 0.5m freeboard (SC6.7.5 Specific Design and Construction Requirements – Clause (2) (m) (iv)). When reviewing the results,
each building achieves the minimum freeboard required. It is noted that FFL2 achieves its freeboard through the inclusion of a wall (approx.
1m high) to contain flows within the flow path. Figure 2.5 provides an overview of finished floor levels, top of wall levels and defined flood
height (i.e. 1% (2100) AEP).
