Dear Belinda

                      Re: MCU25/0053 & OPW25/0074 ~ 7 Noosa Parade Noosa Heads

We have reviewed Noosa Council’s request for information dated 9th June 2025 and provide our response to the
Engineering related items.

Issue: 1 - Stormwater
      The Stormwater Management Plan for the basement level includes a pump system. Council
      has concerns how stormwater will be managed in the event of a pump malfunction.

      In accordance with QUDM 7.2.3 address how a major (1% AEP) event will be managed
      in the event of a pump malfunction.

Response:

As detailed in the submitted Stormwater Management Plan (SCG Drawing. No. 0423-SW1.1 & SW1.2), the
basement drainage system has been designed in accordance with QUDM Section 7.2.3 to include appropriate
redundancy measures.

A secondary pump and a backup power supply will be provided to manage stormwater in the event of a primary
pump failure or power outage. This approach aligns with accepted engineering practice and is consistent with
prior development approvals in similar basement configurations.

These provisions ensure continued functionality of the stormwater system during a major (1% AEP) storm
event, thereby mitigating flood risk associated with pump malfunction.

If you require any further information, please do not hesitate to contact our office.


Yours faithfully
