11 our adaptation hierarchy We have many options to respond to coastal hazards, ranging from revegetation and other ecological approaches, to engineering solutions like seawalls, right through to transitioning and relocating assets.
To decide which options work best at which time and place, we refer to the ‘adaptation hierarchy’ which provides a priority of adaptation. The hierarchy favours avoidance, protection and restoration options as a first approach
in adapting to coastal hazards. Preferred options are those that will be prioritised or the short term, however less preferred options will be implemented when they become necessary.
