A long history of flood management
A long history of flood management
Over the past five years Council
has invested $600 million
towards flood management:
• Extensive pipes and
drainage works
• Backflow devices
• Flood information online
for residents and
businesses
• Lord Mayor’s Taskforce
on Suburban flooding
2011 Brisbane River Flood
2011 Brisbane River
Flood
Volunteers were
everywhere and
made a difference to
the people who had
been flooded
Government response
• Qld Floods Commission of Inquiry and
BCC Flood Action Plan
• Focus to make Brisbane more
resilient to flooding disasters
• 124 recommendations and
improvements for Council:
• Floodplain management
• Planning and building
• Emergency response and
dam management
FloodSmart Future Strategy
The Behaviour Response - A FloodSmart Future
• Flooding is complex, technical and often difficult to explain
• Flooding is also a natural part of living in a sub-tropical
climate
We wanted to communicate a story.

Well Maintained & Improved
Structural Assets• Historical focus of flood
management
• Significant investment in the 1980’s
following 1974 flood
Stormwater Relief Drainage
• Asset Value of $2.9 billion
• 2,700km of pipes/culverts
Investment in Backflow
Prevention Devices
Well Maintained
& Improved Structural
Assets
New generation ferry terminals
– Brisbane River
Detachable gangway
• Detach at shore end
• Rise and fall with flood
waters
• Swings behind pontoon
to avoid debris
Hull shaped base/pontoon
Single pier
• 11 metres high
• Capacity to deflect heavy
objects
• Avoids impact on pontoon in
flood event
Voluntary Home Purchase Scheme
• Voluntary purchase of homes
affected by a 50% annual chance
creek flood event and overland
flow
• 112 properties purchased for over
$58.4m million
• Previously 30% take up – post
flood 100%
Well Maintained & Improved
Structural Assets

providing flood resilience
information and
recommendations for the
property.

• Use 3D scanning data from
autonomous vehicles
Opportunities
Conclusions
