Acceptable outcomes

and design of the development to protect and retain

identified ecological values and underlying ecosystem

processes within or adjacent to the development site to
the greatest extent practicable. This includes:

(1) maintaining or restoring vegetated buffers between
development and coastal waters to the extent
practicable, unless the development is within ports or
airports, or is marine development

(2) maintaining or enhancing the connectivity of
ecosystems in consideration of the cumulative effect
of the development in addition to existing developed
areas

(3) retaining coastal wetlands, seagrass beds and other
locally important feeding, nesting or breeding sites for
native wildlife.

containing Matters of State Environmental Significance for
Regulated Vegetation intersecting a watercourse. This
mapping matter is irrelevant to the site because the area
where the works are proposed is all hard infrastructure. Due
to surrounding infrastructure, vegetation restoration and
enhancement is not appropriate or relevant in the location
for the small scale of the proposed project.

 

  

 

AO7.6 Measures are incorporated as part of siting and
design of the development to maintain or enhance water
quality to achieve the environmental values and water
quality objectives outlined in the Environmental Protection
(Water) Policy 2009.

AND

The proposal is intended to prevent the current uncontrolled
under mining and scour of the road which is currently
releasing sediments into the river.

 

AO7.7 Development avoids the disturbance of acid
sulphate soils, or where it is demonstrated that this is not
possible, the disturbance of acid sulphate soils is carefully
managed to minimise and mitigate the adverse effects of
the disturbance on coastal resources.

A small amount of insitu soils below the level of mean low
water springs will require disturbance for keying in the toe of
the batter. It is anticipated that the contractor will undertake
this section of work by pushing the bucket head in the
sediment enough to laydown the fabric and overlay the
500mm of rock. The amount of disturbance for this part of
the activity is less than 100m3 and most importantly
displaced sediment will not become oxidised.

 

 

PO8 Coastal protection work is
undertaken only as a last resort where
erosion presents an imminent threat to
public safety or permanent structures.
Editor’s note: Applications for coastal
protection work must be supported by a report
certified by an RPEQ that demonstrates how
the engineering solution sought by the work
will be achieved.

A08.1 Coastal protection work is only undertaken to
protect existing permanent structures from imminent
adverse coastal erosion impacts, and the structures
cannot reasonably be relocated or abandoned.

AND

The repair of the revetment works is necessary to allow
repair and prevent further undermining of the adjacent road.
The existing road provides access to houses and so cannot
be relocated or abandoned.

 

 

AO8.2 Coastal protection work to protect private
structures is undertaken on private land to the maximum
extent reasonable.
