An external review of the original flood report was undertaken on behalf of Council by Switchback
Consulting which indicated that the applicants flood modelling was appropriate and that the
provision of building envelopes filled above the PMF was an acceptable outcome. The revised
layout and reports have been further reviewed by Switchback Consulting, who confirms that the
assessment and revised layout are appropriate.
As detailed in the previous planning report, concerns were raised as to the impacts of flooding on
the greater road network and implications for safe evacuation of the site and access to urban
services. The applicant’s updated Flood report has been amended to include a further assessment
with regard to flooding and the provision of a flood warning system. An extract from the report is
included below:
This development has been designed to provide flood free access to all lots via the new internal
road in events up to the 10% AEP and will remain trafficable in events up to the 1% AEP event in
accordance with the Queensland Urban Drainage Manual (QUDM).
Further consideration of flood risk has been undertaken in events greater than the 1% AEP event,
