AO2.3 Development within a coastal hazard area is
located, designed and constructed to ensure exposed
structures can sustain flooding from a defined storm tide
event.

AND

Given that the development layout of roads and houses is
already established, this performance outcome is not
relevant to the construction of the revetment wall.
Nevertheless, reconstruction of the revetment wall will allow
the road to sustain flooding. At present the revetment wall is
inappropriately constructed/maintained and so the road is
being undermined by tidal flows.

 

AO2.4 Essential community service infrastructure is:
(1) located so that it is not inundated by a recommended
storm tide event specified for that infrastructure, or
(2) located and designed to ensure any components of
the infrastructure that are likely to fail to function or
may result in contamination when inundated by a
storm tide (for example, electrical switch gear and
motors, water supply pipeline air valves) are:
(a) located above the peak water level for a
recommended storm tide event, or
(b) designed and constructed to exclude storm tide
intrusions or infiltration (including by being
located in the ground), or
(c) able to temporarily stop functioning during a
recommended storm tide event without causing
significant adverse impacts to the infrastructure
or the community.

AO2.5 Emergency services infrastructure and emergency
shelters, police facilities, and hospitals and associated
facilities have an emergency rescue area above the peak
water level for a recommended storm tide event.

PO3 Development directly, indirectly and
cumulatively avoids an unacceptable
increase in the severity of the coastal
hazard, and does not significantly
increase the potential for damage on the
premises or to other premises.

 

 

AOQ3.1 Development avoids increasing the number of
premises from which people would need to be evacuated
to prevent death or injury from a defined storm tide event.

 

 

Reconstruction of the revetment wall will not increase the
number of premises from which people would need to be
evacuated. Infact, reconstruction of the revetment wall is
necessary to prevent road collapse and associated injuries
that could be sustained in the event the road fails due to
inadequate protection associated with the existing revetment
