This result is due to risks to ‘Dog Beach’ and surrounds. Lions Park was rated medium risk by 2100.
Given a range of socio-economic, environmental, and governance considerations, as well as

pathway for responding to frequent inundation risks in this locality is one that supports existing
accessibility and infrastructure services, as well as current levels of residential, commercial and retail
development. In response to these risks, the preferred adaptation outcomes are:
