Determining tolerability to risks

Ultimately, determining which coastal hazard risks to respond to and how we do that is based upon
Council and the Noosa community’s tolerance to risk and appetite for certain adaptation actions.
Generally, lower risk levels are more tolerable and require less intensive management actions (e.g.
ongoing monitoring) with less urgency than higher risk levels. The risk tolerance scale in Table 2
outlines how the risk categories may be interpreted or acted upon. Many risks that are considered
low or tolerable today, are expected to become intolerable as the level of risks increases over time.
Some may take quite some time to reach an intolerable level (e.g. not until the year 2100),
whereas others may be reasonably expected to transition from tolerable to intolerable within the
next twenty years.
