banks of any tidal water,

CCA treated timber piles) and the
replacement with 9 concrete marina piles will
improve the flow of water and reduce the on-
going impacts of the use on the bed and
banks of the tidal water.

 

12.4 Design,
construction &

The design and construction of the prescribed
tidal work is consistent with the relevant
Australian Standards.

The proposed marina piles are to be
constructed of concrete, and the pontoon of
plastics, accordingly it is considered the
proposed works will be resistant to attack
from marine organisms, corrosion and
deterioration resulting from abrasion or
immersion in seawater.

It is noted that it is due to the existence of
white ants and ship wonns in the existing
timber piers that the works are sought to be
undertaken.

 

12.5 Design,
construction &

The design and construction of the prescribed
tidal work fs consistent with the following
standards-

{a) vessels moored at prescribed tidal work
do not impede the discharge of stormwater,

(b) prescribed tidal work does not restrict
access to any stormwater outlet.

The closest stormwater outlet to the subject
Site is located on the eastem side of the
Pelican Boats jetty. Accordingly it is
submitted that the proposed works will not
impact on the stormwater fiows into the River.

 

12.6 Design,
construction &
safety

The design and constnuction of the prescribed
tidal work is consistent with the relevant
Australian Standards.

All proposed works are to be undertaken in
accordance with the relevant Australian
Standards with relation to release of
construction materials, sediment disturbance
and exposure to acid sulfate soils.

in this regard it is noted that the existing
timber piers proposed to be removed are
located in pure sand, which is unlikely to be
harbouring acid sulfates. Nonetheless, the
applicant submits that upon the removal of
the first pier, should evidence of substrate
other than sand be viewed, all works shall
cease until a sample of this material can be
tested. Should the presence of acid sulfate
soils be detected, then bumt lime will be
simultaneously injected into pier holes upon
their removal. Conditions detailing this may
be recommended.

 

12.7 Design,
construction &

The design arid construction of the prescribed
tidal work is consistent with the following
standards- :
{a) any surface of prescribed tidal work on
which a person may stand or walk is—
()) not slippery; and
(i) does not have any feature that
may cause the person to trip or
fall,

(b) any part of prescribed tidal work that is
unsafe for persons standing or walking on the
work is surrounded by adequate barriers to
deter persons from entering the part.

As can be seen in the attached photographs
of the proposed product, the surface of the
pontoons are textured to ensure they are not
slippery. Further the joins of each module are
recessed into the unit to ensure they do not
create a trip hazard.

No part of the proposal presents an unsafe
area for persons to access. Itis noted that.
the purpose of the proposed works is to
improve the safety of the facility for both
customers and staff.

 

12.8 Design,
construction &

The design and construction of the prescribed
tidal work is consistent with the following
standards-

Conditions may be recommended
accordingly.
