This is discussed further in Section 7.4.4.


Issue – Extreme local flooding
The local flood inundation maps provided with the IWMP show that the access points to the development will
be inundated in the DFE. In extreme events, workers and visitors to the site will be isolated and evacuation
not possible. It should be demonstrated how their safety will be protected in such extreme events as required
by Specific Outcome O17 of the Noosaville Locality Code.
Information Required
Provide mapping for the PMF and a risk assessment for extreme events which demonstrates compliance with
Specific Outcome O17 of the Noosaville Locality Code. Specifically, the proposal is to demonstrate how the
safety of people at the site will be protected during extreme flood events.
Response
The site remains accessible during the 1% AEP event. Mapping for the PMF shows that there is minimal risk
to persons during an extreme event with site access being maintained for all except small vehicles and no
inundation to the building footprint or carpark areas. The PMF maximum water level at point 5 (Figure 7-12) is
reduced by approximately 100 mm in the developed case.
These results are detailed in Section 7.4.4
