 FLOOD CONSIDERATIONS

     4.1. Noosa River
The subject site is located adjacent to the Noosa River. Noosa Shire Council Intramaps indicates that the site is
located above the current 1% AEP flood event, however Gympie Terrace and Thomas Street are subject to minor
inundation during this event. A copy of Council’s flood mapping layer is shown below in Figure 4-1. No impacts to
site access are envisioned as a result of this.


                                                                                                 Flood Inundation Zone

Council has previously advised that a minimum finished floor level of RL 2.7m AHD is required for the site to
provide flood immunity for future climate change and increased flooding associated with storm tides and sea level
rises. The site currently has an average elevation of around 1.7m AHD. Therefore, the site will need to be filled by
approximately 1m to achieve climate change requirements.


     4.1. Tide Levels
The current tide levels have been obtained from Maritime Safety Queensland. The closest tide / port location
available is Munna Point which is approximately 500m downstream of the site. The current HAT level for Munna
Point is RL 0.654m AHD.

The invert levels of Council’s existing drainage network at the site varies from around RL 0.54m to 0.94m AHD.
Some of Council’s existing network is below the current HAT level.
