When disasters strike, they strike hard & unexpectedly
and the ramifications can be cataclysmic. It is imperative that urban planners
seek disaster risk reduction strategies to ensure that their is a recognition
of the deep connections between human settlements and risk profiles relating to
disasters. These risk profiles can include defective infrastructure, the
inter-relationships between larger cities and their surrounds and the impacts of
cities themselves upon the surrounding environment. During the 2009 Victorian
Bushfires, otherwise known as Black Saturday, an event deeply embedded as one
of Australia's most devastating natural disasters, 173 people lost their lives
whilst over 3,000 building were destroyed. Why did this happen? How did so many
lives ended up being lost?
The events on the 7th February 2009 coincided with one of
the hottest periods in Victoria's history with the mercury pounding to over 46
degrees in Melbourne whilst wind speeds didn't ease Mother Nature’s wrath with
a staggering 115km/h in areas of utter dryness. This is a recipe for disaster
in the context of bushfire risks however this disaster tells us more than what
it is. So what went wrong? Well firstly residents that lived in the risk zones didn’t
have a strategy in placed, rather more of a wait and see policy. Infrastructure
wise, accessibility was at a minimum, electrical aging assets increased fire
risks, and roads were narrow whilst buildings such as homes, schools and
businesses were completely exposed to the fires. Location was also another
reason for why these fires were so rampant. Dense bushlands surrounding poor
infrastructure, especially old and faulty electrical towers should be seen as
one of the primary reasons for the fires. The complete entrenchment of these
communities in the bush accelerated the risk of collateral damage. As planners
we must understand how to adjust communities to ensure they are less likely to
suffer the full severity of natural disasters. Despite the Royal Commission’s
recommendations to improve standards in buildings with local conditions in
mind, I believe there are better alternatives to prepare communities for the
worst from a planning point of view. These include forward strategic planning,
design of settlements to ensure that there is a safe distance from hazardous
infrastructure such as electric lines, development control to ensure that
standards are strictly kept accordingly, improved building controls, improved
warning and response systems so that residence are notified of any likely
fires, community education, forestry management, and rules for
reconstruction. Back burning on open plains will significantly reduce the risks of fire travelling from one patch to another with the assistance of the wind.
In the context of natural disasters, we as urban planners
must create strategies and plans to ensure that disaster impact is kept at a
minimal, in terms of human costs and infrastructure damage. The Victorian
Bushfires gives us an understanding on the implications of poor planning and
what the ramifications are when disaster strikes.

Definitely interesting to consider how planning can assist with disaster mitigation. The recommendations you have made are comprehensive and important to consider in light of construction being undertaken in the area again.
