natural coastal processes, and lead to adverse impacts on neighbouring areas
- Begin re-locating recreational assets outside the project high risk coastal erosion prone area
by 2040, such as seating and footpaths
- Re-locate service infrastructure assets to areas outside the high-risk area by 2070
- Where important recreational and service infrastructure assets cannot be feasibly located,
seek to accommodate the risks by adapting the design of these assets to be more resilient
during and after a major erosion event.
- Ensure development in erosion prone areas mitigates the risk to people and property to an
acceptable or tolerable level, consistent with the State Planning Policy – natural hazards risk
and resilience.
These risk results are being driven by the potential high level of exposure of private assets along Arakoon and

Seaview Tce. Properties on beachfront streets south of the Sunshine Beach SLSC have a lower risk rating.
