Our city, people, houses, infrastructure and other assets could potentially be impacted by a number of natural hazards such as earthquakes, erosion, extreme rainfall, and tsunami.
The aim of the resilience project is to provide for robust infrastructure and informed land use planning, so we can improve the city’s resilience to natural hazards.
Understanding the risks and their consequences is a critical element in this process. Then the way we respond, with design, adaptation or retreat, will bring us closer to the goal of a resilient city.
The resilience project will use updated data on natural hazards and quantify their impact on the city’s infrastructure assets, then evaluate the vulnerability of the city’s assets to these hazards and determine how to mitigate these risks.
Natural hazards and impact on infrastructure
We have been researching, mapping, planning for and informing our community about natural hazards for over 20 years now. We continue to collect new data, and update existing data on a rolling basis – to ensure it covers our whole city, and that it responds to changes to the environment like projections for sea level rise.

The resilience project will look at the probability of natural events, and the impact they may have on the city’s infrastructure.
Evaluating the vulnerability of assets and determining appropriate mitigation
Continued operation of the city’s infrastructure during a natural hazard event is critical to us surviving and recovering from a disaster. Of particular focus is the capacity of our roads and water systems to absorb these shocks and recover quickly afterwards.
The resilience project will use the hazard information we have gathered and design ways to reduce the damage these events cause to infrastructure. A simple mitigation project may be to provide space for a generator to be plugged into a pump station. A larger example could be to change pipes in liquefaction zones to stronger materials.
Many of these outcomes will apply to our future planning so that we can avoid or design for events like liquefaction and flooding.
The research phase of the resilience project is expected to be completed in 2021.
