After the deluge: Brisbane's new flood resilient ferry terminal

After the deluge: Brisbane's new flood resilient ferry terminal | green streets | Scoop.it

Cox Rayner Architects and Aurecon have designed a new generation of flood-resilient ferry terminals in Brisbane.

The completed terminal at Milton is the first of many to be rolled out along the Brisbane River in 2015. The flood resilient terminal design has been inspired by the way private pontoons simply float over their piers in a flood. Michael Rayner, director of Cox Rayner, called on his own experience in the 2011 floods in designing a terminal that could also deflect debris.

The design features a pier that provides commuters with panoramic views of the Brisbane River, with the pontoon essentially tethered to the pier via the gangway. During a flood, the gangway slides across the pier as the river rises and detaches. It then swings with the current of the flood waters, secured to the side of the pontoon, to avoid the build-up of debris. The gangway incorporates a unique floor which maintains level whatever the tide. The pontoon, which is anchored at the downstream end, features a hull-shaped base that allows flood waters to flow underneath it unhindered.

Kris Homann's curator insight, March 18, 3:53 AM

Brisbane has been my home for my entire adult life.  I moved here the day I graduated high school and will most likely live here the rest of my life.

 

As a city, Brisbane has had it’s fair share of major incidents, the most notable of late the 2011 floods.  In some ways, we are still feeling the flow on effects from this today, as can be seen in this article, they have had to completely redesign the ferry terminals to cope with future flood events, and as a result of the floodings, insurance companies were forced to change their policies to cover flood events .

 

Another recent OHS issue that is becoming more prominent is traffic in the city.  Roads everywhere are congested because they can’t cope with the traffic volumes, people are more and more starting to ride push bikes on roadways, that are not designed to be shared use, so the incidents of vehicle to bike accidents has skyrocketed.

 

Both the floods and the bicycle usage have caused many OHS issues to come up, some of which are how to make the roads safer, and less congested, how do we flood proof our beautiful city, and how do we do this without having a negative impact on the people who are required to do the work to implement these changes.

 

Widening roads is a dangerous situation for the workers, and one that has caused concern in the past, especially with impatient drivers who refuse to slow down through traffic works effectively putting the lives of the workers at risk.  So how do we do this safely, and how do with do it with minimal obstruction to already overturned roadways? 

 

That is something I would like to find out.

Climate-Proofing Urban Areas with Floating Housing

Climate-Proofing Urban Areas with Floating Housing | green streets | Scoop.it

The wave of floods that hit Britain in April focused attention, once again, on the vulnerability of homes in low-lying areas...

But what if a house could simply rise and fall with the waters? That’s the vision of Baca Architects, designers of the UK’s first ‘amphibious house’, which has just received planning permission for a site near Marlow, in Buckinghamshire, on the banks of the Thames.

The lightweight, timber-framed structure sits on a floating concrete base that is built within a fixed ‘wet dock’ foundation. In the event of a flood, the concrete base rises up as the dock fills with water, ensuring the house floats safely above the waves. The base effectively acts as a free-floating pontoon, and should have a lifetime of around 100 years before needing renewal or replacement.

Climate proofing’ urban areas is a growing area of focus for architects and planners. Amphibious architecture looks set to join rain gardens, green roofs and permeable paving in the array of techniques available...

Creative concept. I wonder how they plan to ensure grounding / earthing the electrical system.

Planning for Climate Change: 5 Ideas to prevent flooding in New York

Planning for Climate Change: 5 Ideas to prevent flooding in New York | green streets | Scoop.it
It's time to start seriously planning for climate change in the city.


New York City didn’t have to flood quite this badly, or, at least, it doesn’t have to again. There's no shortage of ideas out there for how the city could adapt to rising sea levels (or, we’ll just say it: climate change). A lot of them haven’t been deployed or more seriously studied because they seem too expensive or daunting.


But an event like Sandy quickly changes that calculus. Suddenly, some of these solutions don’t look quite as expensive as cleaning up after a hurricane...
