Floods cannot be prevented, but with good strategic planning and management, loss of life can be avoided, and damage to property can be minimised. The key to minimising the impact of floods is preparation, and to that end, everyone has a role to play. The federal and state governments need to come up with comprehensive and executable plans based on lessons from past flooding events. So far, some states have been doing their part, for example, the Victorian Government launched its Floodplain Management Strategy to help communities prepare for future flooding events. Management strategies are created to ensure that communities know what measures to take while preparing for floods as well as what actions to take during actual flooding events. If everyone (including property owners, developers, local planning departments, and disaster relief personnel) adheres to the recommendations in the Floodplain Management Strategy, the loss of life and property could be avoided.
Understanding the commonly used term 1 in a 100 flood is key to understanding the risk as Stephen Molino points out in his article Tough Lessons There is a popular misconception that a 1 in 100 flood only occurs once every one hundred years
However these fears are ungrounded as property values continue to soar even when these models are released to the public. Learn from past floods We should collectively look at what happened during past floods, and ask: What could we have done better? The following four main areas will provide the biggest impact and reduce the amount of damage caused by future flooding events for the least expenditure are: Include flood mitigation best practises into building codes for areas at risk of flooding. Invest in flood mitigation measures such as levees Education Press on Federal and State Government to restore funding for mitigation measures After the flooding disaster in Queensland in January 2011, this article in the Australian stated: If not for its recently built levees, 80 per cent of St George would have gone under. How much does it cost to build a levee compared to restoring 80 % of a town? While levees are now under construction in some Queensland towns, that state still does not have a flood-plain management policy to discourage inappropriate development on flood plains, which is in sharp contrast to other states. The article also points out the attrition of government funding away from preventive measures: Many years ago, there was a 2:2:1 funding arrangement between federal, state and local governments for flood mitigation works across Australia. That was changed to the system we have today of a 1:1:1 ratio, which increases the cost burden on local government, making it harder for many, particularly those in rural areas, to be able to afford to do anything. If you are a homeowner building your home in a risk area ask yourself this, wouldn't you prefer one-off higher construction costs based on better design and materials than ongoing high insurance premiums and the risk that you may lose your possessions, the house itself or worse still lose the life of yourself or a loved one? And, as a taxpayer wouldn't you rather your taxes were wisely spent on mitigating the impacts of disaster through education and well planned and executed design that could prevent a lot of the disastrous impacts rather than shouldering the cost of cleaning up and rebuilding infrastructure afterwards? If we ignore the lessons that we've learned from past floods, we are doomed to suffer similar (or worse) devastation in the future.
