Planning for Brisbane airport’s new runway: accounting for climate change
The second runway at busy Brisbane Airport is being built 1.5 m higher than regulations dictate to take into account risks associated with storm surge and sea-level rise
Brisbane Airport is the third busiest airport in Australia. Close to Moreton Bay, the airport is low lying. Continual increase in demand has resulted in the construction of a second parallel runway. To ensure that the airport can operate continually over its projected lifespan, it was important to consider climate change implications in the design. Accordingly, a runway height of 1.5m above the minimum regulatory requirements was adopted. Other climate change adaptation actions were also implemented including channels to reduce tidal flooding, and construction of a seawall. Stakeholder engagement around the design was considerable: conducted over a period of almost two years it implemented a range of engagement options.
