Table 10.1.1: All development
Performance outcomes
PO1 Development in a coastal hazard

area is compatible with the level of
severity of the coastal hazard.

Acceptable outcomes

A01.1 Development is located outside a high coastal

hazard area unless it is:

(1) coastal-dependent development, or

(2) compatible with inundation due to its nature or
function, or

(3) temporary, readily relocatable, or able to be
abandoned, or

(4) essential community service infrastructure, or

(5) small - to medium-scale tourist development, or

(6) redevelopment within an existing built-up urban area,
or is redevelopment of built structures that cannot be
relocated or abandoned.

Comment

The proposed revetment wall is designed to withstand
inundation and is redevelopment of an existing
unmaintained revetment wall. The proposed revetment wall
and pathway meet AO1.1 (2) and (6)

 

AO1.2 Development referred to in AO1.1(6) avoids being
located within a high coastal hazard area, or where this is
not practicable, minimises the exposure of people and
permanent structures to coastal hazard impacts.

The reconstruction of the revetment wall is proposed to
protect road infrastructure and therefore minimises the
exposure of people and permanent structures to coastal
hazard impacts.

 

 

PO2 Development siting, layout and
access in a coastal hazard area
responds to potential inundation due to a
defined storm tide event and minimises
associated risks to personal safety and
property.

AO2.1 Development within a coastal hazard area is
located, designed, constructed and operated to maintain
or enhance the community's resilience to defined storm
tide events by limiting the exposure of people and
structures to associated impacts.

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, the reconstruction of the revetment wall is
proposed to protect road infrastructure and therefore allows
the community to become more resilient to coastal hazard
impacts.

 

 

AOQ2.2 Development mitigates any residual impacts from
storm tide inundation in a coastal hazard area including by
ensuring:

(1) habitable rooms of built structures are located above
the defined storm tide event level and any additional
freeboard level that would ordinarily apply in a flood
prone area under a relevant planning scheme
standard, or

(2) a safe refuge is available for people within the
premises during a defined storm tide event, or

(3) atleast one evacuation route remains passable for
emergency evacuations during a defined storm tide

 

 

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 is
necessary to reduce potential undermining of the road and
therefore increase evacuation routes/reduce recovery time
after a surge event, thus satisfying A02.2.
