Executive Summary
This Review of Environmental Factors (REF) relates to areas of Hickson Road,
Sussex Street, Napoleon Street, Shelley Street and an area within the Barangaroo
South development site that will be reserved as Watermans Quay in the future
(the ‘REF Site’). The REF Site is located immediately east of the Barangaroo South
development site.
The proposed works (the ‘Activity’) at the REF Site will upgrade the existing
stormwater system, regrade the road pavement within the REF Site and install
new landscaping to:

resolve existing ponding of water on Hickson Road in storm events, including
ponding that has the potential to flood the Sussex Hotel in a 100 year ARI
event as the existing stormwater drainage system is inadequate;

address the potential for the existing flooding to be exacerbated by sea level
rise in the future and the interruption of overland flow paths from Hickson Road
across the Barangaroo South development site when the public domain is
complete;

improve the amenity of the streetscape and its relationship with the proposed
permanent public domain works at Barangaroo South; and

respond to the raising of the ground level of the adjacent Barangaroo South
development by approximately 900mm through increasing the level of the
adjoining roads to better relate to the new ground level at Barangaroo South.
The Activity involves the following components:


construction works, including;

This REF has been prepared in accordance with the requirements of all potentially
relevant NSW and Commonwealth legislation. The REF has been prepared in
accordance with Clause 228 of the Environmental Planning and Assessment
Regulation 2000. In doing so, the REF satisfies the requirements of Section 111 of
the Environmental Planning and Assessment Act 1979 (EP&A Act), which requires
the Barangaroo Delivery Authority to examine and take into account to the fullest
extent possible, all matters affecting or likely to affect the environment as a result
of the activity.
The Activity will have the following key benefits:

introduce cycle infrastructure to Hickson Road within the REF Site;

reduce the local flood risk for a 100 year ARI storm event to within the City of
Sydney requirements;

manage the risk of sea level rise; and

improve the public domain in the area by providing a new carriage way,
footpath, street furniture and landscaping and improve the relationship between
the road and adjacent properties including the future public domain at
Barangaroo South.
The key adverse impacts of the Activity include:

the removal of existing street trees; and

short term construction impacts.
Potential adverse impacts identified within this REF will be appropriately managed
in accordance with the mitigation measures outlined in Section 8 and the
measures set out in the Activity-specific Environmental Construction Site
Management Plan, prepared by Lend Lease, who will undertake the works on
behalf of the Barangaroo Delivery Authority. These mitigation measures will
ensure that the Activity is delivered in such a way that it both maximises benefits
to the wider community, and minimises any potentially adverse impacts to the
community and the environment.
In considering the overall potential environmental impacts and the proposed
management and mitigation measures outlined in this REF, the Activity is not
anticipated to have a significant effect on the environment for the purpose of
s112 of the EP&A Act.
On balance, it is considered that the benefits of the Activity outweigh any
environmental impacts and that the Activity should proceed.

1.0 Introduction
This Review of Environmental Factors (REF) has been prepared by JBA to examine
and take into account to the fullest extent possible all matters affecting or likely to
affect, the environment by reason of the Activity, as defined in Section 3. The
Activity is proposed to be carried out by Lend Lease (Millers Point) Pty Ltd on
behalf of the Barangaroo Delivery Authority.
1.1
Activity Background and Overview
The REF Site is located immediately east of the Barangaroo South development
site as shown on Figure 2.
Works to the road are required to prevent future stormwater management issues
and also to improve the public domain and road infrastructure in the vicinity of
Barangaroo South.
There is existing ponding of water on Hickson Road which has the potential to
flood the Sussex Hotel because the existing stormwater drainage system does not
meet the current City of Sydney requirements for conveyance of 100 year (ARI)
stormwater.
Furthermore, when completed, the ground level of the Barangaroo South precinct
will have been raised to above the existing level of Hickson Road in order to
address potential future sea level rise. This will permanently alter existing overland
stormwater flow paths such that existing ponding of water on Hickson Road will
be exacerbated unless works are undertaken to improve the capacity of the
stormwater system and manage ponding distribution at surface level.
The Activity will upgrade the existing stormwater system, regrade the road
pavements within the REF Site and install new landscaping to:

resolve existing ponding of water on Hickson Road in storm events, including
ponding that has the potential to flood the Sussex Hotel in a 100 year ARI
event as the existing stormwater drainage system is inadequate;

address the potential for the existing flooding to be exacerbated by sea level
rise in the future and the interruption of overland flow paths from Hickson Road
across the Barangaroo South development site when the public domain is
complete;

improve the amenity of the streetscape and its relationship with the proposed
permanent public domain works at Barangaroo South; and

respond to the raising of the ground level of the adjacent Barangaroo South
development by approximately 900mm through increasing the level of the
adjoining roads to better relate to the new ground level at Barangaroo South.
As part of the Activity, Lend Lease proposes road works in Hickson Road, Sussex
Street, Napoleon Street, Shelley Street adjacent to the Barangaroo South, and to
an area of Barangaroo South that will be reserved in the future as Waterman’s
Quay (Globe Street). The Activity involves the following works:


Detailed Description
The Activity will improve the existing road and footbath pavement along Hickson
Road, Sussex Street, Napoleon Street and Shelley Street. The Activity will also
take place in an area of the Barangaroo South precinct that will be reserved as
Watermans Quay.
The Activity will address existing stormwater management issues and increase the
current level of the road pavement to better relate to the future level of the
Barangaroo South precinct to the west of Hickson Road.
The Activity will introduce a central median strip to Hickson Road along with a taxi
rank and additional parking bays on the western (northbound) carriageway. A
cycle path will be provided on the eastern (southbound) carriageway. The cycle
path will allow bi-directional travel to allow for connection to the broader cycle
network planned for the CBD.
Traffic signals will be installed on the Hickson Road/Napoleon Street intersection
and also the Hickson Road/Watermans Quay intersection.
As the REF Site is a Classified Road concurrence is required from RMS for the
proposed road works.
Improved street furniture and signage will be installed as part of the Activity. Civil
drawings of the REF Site following the Activity are provided in Appendix A and
landscape plans are provided in Appendix H.
Tree Removal
Existing Ficus microcarpa var. ‘Hillii’ (Hills Weeping Fig) trees are located along
Hickson Road. Where these trees are located within or adjacent to the REF Site,
they may be affected by the Activity.
The trees to be removed have been assessed within the Arboricultural report
attached to the REF as Appendix E. Trees that are to be retained have been found
to be in good health and suitable for retention.
Planting of new street trees is proposed as part of the landscaping works
associated with the Activity. The details of proposed landscaping works are
provided in Appendix H and include:

the installation of standard City of Sydney tree pits on the eastern and western
side of Hickson Road, planted with Liriodendron tulipfera and Fraxinus
pennsylvanica; and

planting of 7 Livistona australis in the Hickson Road median strip.
Parking
Timed on street parking is located on both the east and west sides of Sussex
Street. The exact number is not known as there are no marked spaces. The
Activity will provide timed parking on the east side of Sussex Street between 9am
and 3pm. It is intended the area will be a clear way between 3pm and 8pm to
ensure both south bound lanes are functional. Parking is to be provided on the
western side of Sussex Street. Seven (7) parking spaces are to be provided along
with five (5) taxi bays to the southern extent of the works. A minimum of thirty
(30) bike parking spaces will be provided. General parking arrangements are
detailed on the civil engineering drawings 460 and 461, provided at Appendix A.
Pedestrian Crossings
On grade pedestrian crossings are located at the signalised intersection with
Napoleon Street and the proposed mid-block signalised pedestrian crossing located
8
JBA  10051
Barangaroo South

Hickson Road Alterations | August 2015
under the Sussex Street Bridge. These are detailed on drawings 460 and 461
provided at Appendix A.
Fill Material
It is anticipated fill material will need to be imported to facilitate level adjustments
to Sussex Street. Concept earthwork volumes indicate approximately 700m3 of
engineered fill material is required over and above pavement materials. The source
of the material cannot be determined at this stage; however sandstone material
may be available from other projects within the CBD depending on construction
timing. Any fill material used will be validated for use by a suitably qualified
Geotechnical Engineer.
Coordination of RL levels is detailed on drawings 410 and 411 provided at
Appendix A. Smooth connections shall be made with the existing levels of the
surrounding areas.
Public Transportation
Public transport infrastructure within has not been allowed for as part of the
proposed Activity.
However, the possible future light rail has been allowed for in the existing road
corridor. Sketch plans have been discussed with Council and the Barangaroo
Delivery Authority during the preparation of this REF.
Staging
As the Activity will coincide with the closure of George Street due to the
installation of light rail in Sydney CBD, allowance has been made for temporary
bus stops within the REF Site.
A temporary bus stop will be located north of the Napoleon Street/Hickson Road
intersection in both directions. The Activity will be managed in such a way as to
allow for the continued operation of both northerly and southerly bus stops
throughout construction.
3.2
Construction Management
An Environmental, Construction, and Site Management Plan (ECSMP) has been
prepared by Lend Lease and is included at Appendix D. This plan, along with the
management and mitigation measures within Section 8 sets the parameters for
construction methodology and mitigation measures to be undertaken to support
the delivery of the proposed activity.
A detailed Construction Environmental Management Plan (CEMP) will be prepared
prior to the commencement of the Activity. Construction traffic management
arrangements will be detailed in a separate traffic management plan, which will be
finalised prior to construction, based on the outcomes and recommendations of
the construction traffic assessment in Appendix D and the ECSMP.

5.0 Planning Context
5.1
Environmental Planning and Assessment
Act 1979 (EP&A Act)
The EP&A Act is the legal framework through which the use of land is managed in
NSW. The Activity is subject to Part 5 of the EP&A Act.
Section 111 of the EP&A Act requires the determining authority to examine and
take into account to the fullest extent possible all matters affecting, or likely to
affect the environment by reason of the Activity. This REF includes an
environmental assessment, which addresses the requirements of section 111 of
the EP&A Act.
Subsection 111 (2), (3), and (4) of the EP&A Act prescribe that the determining
authority shall consider the effect of an Activity on:

conservation agreements and plans of management entered into under the
National Parks and Wildlife Act 1974 (NP&W Act);

any critical habitat, threatened species, populations and ecological
communities, and their habitats and any other protected fauna or protected
native plants within the meaning of the NP&W Act;

joint management agreements or any biobanking agreement entered into under
the Threatened Species Conservation Act 1995; and

any wilderness area (within the meaning of the Wilderness Act 1987) in the
locality in which the activity is intended to be carried on.
The REF Site is not subject to any existing conservation arrangements to which
the determining authority should have regard under this section of the Act.
5.2
State Environmental Planning Policies
(SEPPs)
The SEPPs which apply to the site of the proposed works and are relevant to the
assessment of the proposal are outlined below.
5.2.1 State Environmental Planning Policy
(Infrastructure) 2007
Development without Consent
Clause 94 provides that development for the purposes of road or road
infrastructure facilities may be carried out by or on behalf of a public authority on
any land, and specifies that ‘alterations or additions to an existing road (such as
widening, duplication or reconstruction of lanes, changing the alignment or
strengthening of the road)’ are included as development for the purposes of road
or road infrastructure facilities.
As works may be carried out on any land, the Barangaroo Delivery Authority is
able to undertake these works on land for which City of Sydney Council is the
appropriate roads authority without consent. Consultation with City of Sydney
Council is outlined in Section 4.
The component of the Activity that is associated with the works to Hickson Road,
Napoleon Street, Shelley Street, Sussex Street and future Watermans Quay are
road works to which Clause 94 applies. The REF Site is not on land reserved under
JBA  10051
11
Barangaroo South

Hickson Road Alterations | August 2015
the National Parks and Wildlife Act 1974 and the proponent is the Barangaroo
Delivery Authority which is a public authority.
Clause 111 provides that development for the purpose of stormwater
management systems may be carried out by or on behalf of a public authority
without consent on any land. The component of the Activity that is associated
with stormwater infrastructure is development to which Clause 111 applies.
All demolition works, including the proposed removal of trees along Hickson Road,
is required as part of the construction works in connection works in connection
with a road or road infrastructure facilities and is therefore undertaken in
accordance with Clause 94 of the ISEPP.
The Activity is ‘permissible without consent’ and can be assessed under Part 5 of
the EP&A Act.
Exempt Development
The Activity also includes several components that can be carried out as exempt
development, as defined by clause 97 of the ISEPP. Clause 97 specifies that the
following works can be carried out as exempt development when carried out on a
road or within a road reserve by a public authority for the purpose of a road or
road infrastructure facilities:

‘erection, installation, maintenance, reconstruction, repair or replacement of
any of the following, and any associated landscaping works:
–
security fencing with a height above ground level (existing) of not more
than 3.2m,
–
safety barriers or systems, including Jersey barriers,
–
directional, safety or other advisory signs relating to road works or the use
of existing road infrastructure facilities,
–
pedestrian and cyclist facilities (such as footpaths, street lighting, kerb
adjustments and ramps, pedestrian fences, refuges, holding rails, and


amenity facilities, including toilets, change rooms and food preparation and
related facilities for persons using public spaces within the site,

information boards and other information facilities (except visitor centres),

lighting if the lighting minimises light spill and artificial sky glow in accordance
with AS/NZS 1158 Set:2010, Lighting for roads and public spaces Set,

maintenance depots used solely for the maintenance of the land or structures
within the site,


irrigation systems (whether or not they use recycled water),

Christmas trees that comply with subclause (2),

demolition of buildings (unless the building is a State or local heritage item or is
within a heritage conservation area) so long as the footprint of the building
covers an area no greater than 250 square metres.
No assessment or approval of exempt development is required under the EP&A
Act. The proposed works that can be carried out as exempt development under
the provisions of clauses 58B or 97 of the ISEPP are incidental to the works that
are permitted without consent and therefore described as part of the Activity
within this REF for context. These works are indicative and may be amended
within the scope of the exempt development provisions in the future if necessary.
Consultation
Clause 14 of the ISEPP requires that where development may be carried out
without consent by a public authority, the public authority must not carry out the
activity if it is not minor or inconsequential on a local heritage item unless it has:

had an assessment of the impact to the local heritage item prepared (a
Statement of Heritage Impact prepared by TKD is included in Appendix F);

given written notice of the intention to carry out the development and a copy
of the assessment to the local council for the area; and

and taken into consideration any response received within 21 days of the
notice.
As discussed in further detail at Section 5.5, the Activity involves the removal of
street trees that form part of local heritage item I1952 in the Sydney Local
Environmental plan (SLEP) 2012. The Activity is also located adjacent to the Statelisted Sussex Hotel.
The Activity will therefore impact on the visual curtilage of a heritage item, but, as
determined by the Statement of Heritage prepared by TKD (Appendix F), the
impacts of the development on items of heritage significance will not be
substantial. As such, although referral under clause 14 of the ISEPP may not
necessarily be required, City of Sydney Council will be notified of the Activity.
Clause 16(2)(d) of the ISEPP requires that where development may be carried out
without consent within the foreshore area within the meaning of the Sydney
Harbour Foreshore Authority Act 1998, the proponent must notify the Sydney
Harbour Foreshore Authority. Part of the site is located within this area. Therefore
notification of the Sydney Harbour Foreshore Authority is to be undertaken under
clause 16 of the ISEPP.

5.2.2 State Environmental Planning Policy (Major
Development) 2005
The Barangaroo site is listed as a State Significant Site under Schedule 3 of State
Environmental Planning Policy (Major Development) 2005 (Major Development
SEPP). The majority of the REF Site is within the Barangaroo Site as defined in the
Major Development SEPP.
The areas of the REF Site located outside of the Barangaroo Site listing include the
southern tip, which relates to works on part of Sussex Street and part of Shelley
Street, and the eastern tip, which relates to works on part of Napoleon Street.
Sydney Local Environmental Plan (SLEP) 2012 is the environmental planning
instrument that applies to these areas (see Section 4.3).
The part of the REF Site covered by the Major Development SEPP is zoned ‘B4
Mixed Use’. Figure 3 overlays the REF Site on a hybrid of the Major Development
SEPP and LEP 2012 zoning maps, and illustrates the parts of the site covered by
each instrument.
Clause 22(1) of Part 12 of Schedule 3 the Major Development SEPP provides that:
This Part does not restrict or prohibit, or enable the restriction or
prohibition of, the carrying out of any development that is permitted to be
carried out with or without consent or that is exempt development under
State Environmental Planning Policy (Infrastructure) 2007.
As detailed in Section 4.2.1 under the provisions of the ISEPP the Activity is
permissible without consent on any land when being carried out by, or on behalf
of, a public authority (except for those elements, as described above, that are
exempt development and for which no assessment or approval is required).

5.2.3 State Environmental Planning Policy 55 –
Remediation of Land (SEPP 55)
SEPP 55 provides for the consideration of contamination and remediation matters
to be considered as part of zoning or rezoning proposals and in the determination
of a development application. The Activity is neither a zoning nor rezoning
application, or a development application. As such SEPP 55 does not apply.
Notwithstanding this, contamination is identified as a relevant issue to be
considered by the determining authority and is therefore addressed in the REF.
The excavation associated with the Activity is minimal, restricted to the area
around the proposed drainage works. During the operation of the Activity, this
area will retain its existing use as a road and footpath, and the final development
will leave the ground in the same condition as it currently is, being covered with
hard stand and unexposed to sensitive receivers.
As detailed in Section 4.4.4, the northern section of the REF Site is adjacent to,
and overlaps with land that is subject to a Declaration No. 21122 as a
Remediation Site under the Contaminated Land Management Act 1997 (EPA
Declaration Area). AECOM have undertaken investigations in the REF Site to
determine the extent of any existing contamination. This report is included as
Appendix M and is summarised in Section 5.10 of this REF.
Based on the previous investigations within the REF Site, including the EPA
Declaration Area, AECOM has concluded that any contamination that is
discovered while carrying out the Activity is likely to be associated with existing
road fill, not with the EPA Declaration Area, and is unlikely to require remediation
to allow the continued use of the REF Site as a road. As such remediation is not
considered to be required and is not proposed as part of the Activity.
In light of the above, the Barangaroo Delivery Authority can be satisfied that the
REF Site is suitable in its current state for its intended use. An unexpected finds
protocol has been established with Appendix M should contamination be
discovered on the REF Site during the carrying out of works as part of the
Activity.
5.2.4 Sydney Regional Environmental Plan (Sydney
Harbour Catchment) 2005
All existing Regional Environmental Plans are deemed to be State Environmental
Planning Policies for the purposes of the EP&A Act.
The REF Site is within the boundaries of the Sydney Harbour Catchment, as
defined in Sydney Regional Environmental Plan (Sydney Harbour Catchment) 2005
(SREP).
For development within the Catchment, the SREP lists several matters under
Division 2 of Part 3 that must be considered by public authorities before they carry
out an activity to which Part 5 of the EP&A Act applies. An assessment of the

Sydney Local Environmental Plan 2012
As identified in Section 4.2.1, part of the REF site is located within the area
covered by SLEP 2012. Figure 3 above identifies that the area of the REF Site
zoned by SLEP 2012 is B8 Metropolitan Centre, with the exception of a small area
of Sussex Street which is located under the Western Distributor and zoned SP2
Infrastructure.
A number of heritage items, listed within the SLEP, are located within and in the
vicinity of the REF Site, outlined below. The REF Site is includes the area that is
referred to within the SLEP 2012 as “Sandstone retaining wall, palisade fence and
Ficus hillii trees (adjacent Napoleon Street) (I1952)”.
The REF Site is also located adjacent to a number of items that are listed as having
local heritage significance within the SLEP 2012 Including:

Former warehouse “MSB Stores” including interior (I880);

Former warehouse “Grafton Bond Store” including interiors (I1813); and

The Sussex Hotel (I1953).
A SoHI has been prepared by TKD and is located at Appendix F and summarised
at Section 5.5 of this REF. The SoHI concluded that the Activity would not have
any significant impact on the locally and State listed items within and in the
vicinity of the REF Site.
The SLEP 2012 contains clauses relating to the preservation of trees (Clause 5.9)
and flood planning (Clause 7.15). These clauses are not relevant to the Barangaroo
Site.

NSW Legislation
5.4.1 Heritage Act 1977
The MSB Stores, the Grafton Bond Store and the Sussex Hotel are listed under the
Heritage Act1977 and are located in the vicinity of the REF Site.
Approval must be granted under section 57(e) to carry out any development in
relation to the land on which a State heritage listed building, work or relic is
situated.
Approval must be gained under section 57(h) to damage or destroy any tree or
other vegetation on or remove any tree or other vegetation from the place,
precinct or land.

Hickson Road Alterations | August 2015
An assessment of the impact of the Activity on these two requirements is
included in Section 5.5.
As outlined in Appendix F Activity would remove some trees that are subject to a
local heritage listing and works in the immediate vicinity of State heritage items.
No works are proposed not directly to State heritage items.
The impact of the Activity on State heritage items is discussed at Section 5.5. The
SoHI concludes that the Activity does not negatively impact the fabric or visual
setting of these heritage items. As such an approval under section 57 of the
Heritage Act 1977 is not considered to be required. However, the Heritage Council
will be consulted in relation to the proposed works.
5.4.2 Threatened Species Conservation Act 1995 (TSC
Act)
The Activity involves the removal of 19 trees along Hickson Road. None of these
trees can be classified as a vulnerable species or other category of species under
the TSC Act. The Activity is not likely to cause significant impacts on any
threatened species or populations, ecological communities or their habitats as
listed under the TSC Act.
5.4.3 Rural Fires Act 1997
The requirement to obtain a Bushfire Safety Authority under s100B of the Rural
Fires Act 1997 is triggered by development on bushfire prone land that involves
the subdivision of land or a special fire protection purpose. The REF Site is not
identified as being bush fire prone. The Rural Fires Act 1997 therefore does not
apply to the Activity.
5.4.4 Contaminated Land Management Act 1997
The northern section of the REF Site is adjacent to, and overlaps with land that is
subject to a Declaration No. 21122 as a Remediation Site under the Contaminated
Land Management Act 1997 (CLM Act).
A Remedial Action Plan has been prepared as part of a Voluntary Management
Proposal (VMP) that has been agreed between the Barangaroo Delivery Authority
and the EPA in relation to addressing the EPA Declaration (VMP No. 20101719).
The RAP, dated 24 July 2013, has been approved by an EPA certified site auditor
and the EPA through the VMP approval process.
Investigations (detailed in the RAP and summarised in Appendix M) show that
there is unlikely to be any contamination encountered in the REF Site that is
associated with the EPA Declaration and that therefore requiring remediation. The
investigations also conclude it is unlikely that contamination will be encountered
that is of a nature that would require remediation to facilitate the continued use of
the site as a road. To mitigate against the unlikely circumstances that such
contamination is encountered however, the RAP includes an unexpected finds
protocol. Any contamination identified as part of the works associated with the
Activity will be managed in accordance with that protocol, as well as any other
relevant provision within the RAP.
5.4.5 Water Management Act 2000
There are no watercourses which traverse the REF Site and the Activity is not
located within 40 metres of ‘waterfront land’. As such a Controlled Activity
Approval is not required to be obtained under s91 of the Water Management Act
2000.

5.4.6 Roads Act 1993
The Roads Act 1993 (Roads Act) grants a roads authority the power to undertake
a range of works, and sets out the obligations for that Authority when undertaking
those works.
The Barangaroo Delivery Authority is the relevant roads authority for the REF Site,
with the exception of the works that occur within Shelley Street and on Sussex
Street, south of the intersection with Shelley Street, where the City of Sydney is
the relevant road authority.
As the REF Site is a Classified Road concurrence is required from RMS for the
proposed road works. The REF must also be referred to the City of Sydney for
approval under Section 138 of the Roads Act 1993 in relation to the works that
are to be undertaken on land for which the City of Sydney Council is the
appropriate Roads Authority.

The provisions of the Environment Protection and Biodiversity Conservation Act
1999 require an action to be referred to the Commonwealth government should
any of the prescribed triggers be met. A checklist of these triggers is provided in
Table 3 below. The Activity does not meet any of the prescribed triggers,
therefore it does not have to be referred to the Commonwealth government.

6.0 Environmental Impact Assessment
The following section provides an outline of the potential impacts of the activity
on the environment, and how these impacts will be managed.
6.1
Environmental Planning and Assessment
Regulation 2000 Considerations
Table 4 below provides a summary checklist of matters to be considered under
clause 228 of the Environmental Planning and Assessment Regulation 2000.
Table 4 – Summary of Activity Impacts
Factor
(a) any environmental impact on a community
As demonstrated in this REF it is unlikely that there will be any adverse
environmental impacts on the community during the construction phase such
as noise, dust or vibration that cannot be addressed as part of the mitigation
measures that will be put into place. Over the long term positive impacts on
the functionality and visual amenity of the road are expected as a result of the
works.
(b) any transformation of a locality
The works form part of the redevelopment of Barangaroo, and therefore form
part of the positive transformation of the western edge of the CBD. The
Activity itself is small component of the wider development and will not result in
any transformation of a locality.
(c) any environmental impact on the ecosystems of the locality
Whilst the Activity requires the removal of existing street trees, this impact is
necessary in order to be able to improve the existing road and footpath
pavement, which is on balance, considered to be a more important outcome.
As detailed at Appendix E, the loss of the trees will not result in adverse
impacts on any sensitive ecosystems and environments. The street trees will
be replaced with new cohesive planting as part of the landscaping scheme
associated with the Activity.
(d) any reduction of the aesthetic, recreational, scientific or other
environmental quality or value of a locality
The Activity does require the removal of street trees, some of which are
heritage listed. These trees contribute to the aesthetic quality of the locality,
however the Activity forms part of an overall upgrade to the streetscape in the
area, which will involve the eventual replacement of these trees.
(e) any effect on a locality, place or building having aesthetic, anthropological,
archaeological, architectural, cultural, historical, scientific or social significance
or other special value for present or future generations
The Activity does require the removal of heritage listed street trees, however
the Statement of Heritage Impact (SoHI) at Appendix F and summarised in
Section 5.5 concludes that the removal of the trees is acceptable.
(f) any impact on the habitat of protected fauna (within the meaning of the
National Parks and Wildlife Act 1974)
The REF Site is not located in a habitat area of protected fauna. It will not
impact on the habitat of any protected fauna.
(g) any endangering of any species of animal, plant or other form of life,
whether living on land, in water or in the air
The Activity is not likely to endanger any species of animal, plant or other living
thing.
(h) any long-term effects on the environment
There will be no long term effects on the environment; mitigation measures will
ensure temporary demolition and construction impacts are minimised.
(i) any degradation of the quality of the environment
Any minor and temporary impacts on the environment will be managed with
mitigation measures to reduce impacts on noise, air, and water quality.

Factor
(j) any risk to the safety of the environment
The activity is not likely to result in a risk to the safety of the environment.
(k) any reduction in the range of beneficial uses of the environment
The Activity will not remove or reduce beneficial uses. The Activity will in fact
improve the existing road and footpath infrastructure as well as the stormwater
infrastructure and therefore provide a beneficial use of the environment.
(l) any pollution of the environment
Minor air, noise, and water quality impacts from construction works may be
generated. Mitigation measures are proposed to minimise pollution to the
environment.
(m) any environmental problems associated with the disposal of waste
As part of the ESCMP provided at Appendix E, the contractor will be
responsible for disposal of waste and any hazardous materials found on the
site. The ESCMP identifies appropriate measures which will be implemented
to ensure adverse environmental impacts are not incurred as a result of waste.
(n) any increased demands on resources (natural or otherwise) that are, or
are likely to become, in short supply
No significant or substantial increased demands will be made on resources
which are or likely to become in short supply.
(o) any cumulative environmental effect with other existing or likely future
activities
The environmental impacts during the demolition and construction have been
assessed in the context of the wider Barangaroo redevelopment, and
mitigation measures will be undertaken to reduce the temporary impacts on
air, water and noise.

Evaluation of Alternatives
As outlined in Section 1.2 the Activity has four key objectives, these are:

to improve and upgrade the functionality of the existing roads within the REF
Site;

to improve the drainage in the area to reduce flood risk and manage the risk of
sea level rise and thereby resolve existing ponding of water on Hickson Road
which has the potential to flood the “Sussex Hotel;

improve the amenity of the streetscape and its relationship with the proposed
permanent public domain works at Barangaroo South; and

respond to the raising of the ground level of the adjacent land at the
Barangaroo South development site by up to approximately 900mm.
A number of options to achieve these objectives were explored. These
alternatives are outlined below.
Do Nothing
Adopting a ‘do nothing’ approach is not considered appropriate as, following
construction of the Barangaroo South precinct, it would result in an unacceptable
change in level between the existing road level and the future level of the adjoining
footpath. It would also result in unacceptable pooling of stormwater following
rainfall events. This situation is not desirable and therefore the ‘do nothing’ option
is not a viable alternative.
Stormwater
It was considered possible to upgrade the stormwater management infrastructure
only, thereby removing the problem of pooling stormwater or mitigate the flooding
impacts potential future sea level rise. Although this option would address one of
the objectives for the Activity it would not enhance the amenity of the street or
address the change in levels between the future Barangaroo South precinct and
the existing Hickson Road. This option was therefore discounted.

Conclusion
In light of the above evaluation, it is considered that the selected alternative (the
Activity) is the most appropriate scope of works to address the specified
objectives.
6.3
Stormwater Management
A flood study of the Barangaroo South area was conducted by Cardno (provided in
draft in Appendix C, a final flood study will be provided for comment).
Assessment and mitigation measures within the study are summarised below.
6.3.1 Assessment
The 100 year ARI map (Appendix C) shows that a significant area of ponding
occurs in the Sussex Street low point to a depth in the order of 710mm (RL2.76).
This shows that the existing Sussex hotel, with a floor level of RL2.78 will be
close to being inundated in a 100 year ARI event. Figure 4 shows the existing
low point and the impact that this point has on the 100 year ARI flood levels on
the REF Site.
Figure 4 – Existing 100 year ARI flood levels
Source: Cardo Flood Study (Appendix C)
Furthermore, Barangaroo is located downstream of a 16.3ha catchment. The
existing pipe system and overland flow path traverse the REF site and drain the
existing low point. However, construction of the Basement Car Park on the
Barangaroo South Stage 1A site will severe the existing overland flow path and
pipe system and require it to be diverted around the site.
The flood study (Appendix C) compared different drainage arrangements for the
site to identify the most appropriate stormwater management system to address
the above issues. The design also takes into account the potential need to
mitigate sea level rise impacts.
The proposed piped drainage system will consist of 2700mm x 1500mm,
2100mm x 1200mm and 1800mm x 1200mm box culverts from the identified
low point to the Darling Harbour outlet. Figure 5 shows the proposed alignment of
the stormwater management system within the REF Site. The stormwater
management system will flow west into Darling Harbour.

Figure 5 – Proposed Drainage Alignment
Source: Cardo Flood Study (Appendix C)
To reduce excessive ponding in Sussex Street, the 100 year event will be
collected at the Sussex Street low point by a series inlet pits.
The Cardno study shows that the Activity will have a positive impact on the area
as there will be a reduction in potential flood depths within the REF Site. The
existing maximum flood depths of 710mm during a 100 year ARI event will be
reduced to 160mm following the completion of the Activity. Whilst the section of
Sussex Street between Napoleon Street and Shelley Street will be regraded to
raise the level in the low point from RL2.00m to approximately RL2.48m, this still
results in a flood depth 120mm lower than the current flood level.
The flood study results also show that for the 100 year ARI event that:

There is a net reduction in the area of low hazard flooding due to the removal
of the deep ponding in Sussex Street which occurs in the existing condition.

The capacity of Hickson Road drainage system will be significantly improved as
a result of the proposed diversion works and that there are no adverse
consequences as a result of the alteration to the overland flow path.
6.3.2 Mitigation Measures
A site wide Environmental Construction and Site Management Plan(ECSMP) (see
Appendix D) applies to the Barangaroo South development site. The provisions of
this plan will be applied to the Activity to manage any potential impacts during
construction. No specific mitigation measures are required following the
completion of the Activity.
6.4
Tree Removal
An Arboriculture Report has been prepared by Tree Talk (Appendix E). Tree Talk
examined the trees on the site on the REF Site, identifying their health and the
potential impact of the Activity. Assessment and mitigation measures within the
study are summarised below.
6.4.1 Assessment
The Arboriculture Report (Appendix E) identifies six (6) trees within area of works
requiring removal due to roadway level changes and road widening.
Two trees were identified as being suitable for retention. These are located in the
southern end of the study area.
6.4.2 Mitigation Measures
Trees that are to be retained must be adequately protected so they can make a
contribution to future landscaping and amenity.
JBA  10051
23
Barangaroo South

Hickson Road Alterations | August 2015
In order to manage and mitigate any adverse impacts on trees to be retained
during the construction of the proposal, Tree Talk has recommended a range of
protective measures. These measures are fully described in Appendix E and have
been incorporated into the Mitigation Measures in Section 8.
Tree No. 7 is large and of particular significance due to its association with a
heritage item (see Section 6.5 below). It is likely to have a large percentage of
roots under the road surface. The removal of bitumen must be performed with
care so as to prevent damage to roots below, and once existing surfaces are
removed an assessment of where roots are located will be useful in fill
management. New paving levels may require modification to accommodate the
tree roots, or alternatively, it may be necessary to bridge over the roots or install
'structural' or gap-graded soils.
As part of the landscaping works associated with the Activity, trees will be
planted along Hickson Road. These will partially offset the loss of existing trees in
the area.
6.5
Heritage and Archaeology
A Statement of Heritage Impact (SoHI) has been prepared by TKD, (Appendix F).
This report is supported by an Archaeological Impact Statement, which was
prepared by Casey and Lowe (Appendix G). Assessment and mitigation measures
within these studies are summarised below.
6.5.1 Assessment
A number of State and locally listed heritage items have been identified within and
in the vicinity of the site including the MSB Stores, the sandstone retaining wall
and trees, Grafton Bond Store, and the Sussex Hotel.
TKD has assessed the Activity against the model questions within the NSW
Heritage Office’s publication Statements of Heritage Impacts. Only two model
questions were answered in the affirmative, comprising ‘new development
adjacent to a heritage item’ and ‘tree removal or replacement’. As such, further
questions have been addressed for these two specific areas.
New development adjacent to a heritage item
The location of the Activity and its relationship to the existing heritage items has
been examined by TKD. It is considered that the Activity will not have a
significant impact on the existing heritage items in the vicinity of the REF Site.
Tree removal or replacement
The Activity requires the removal of some existing street trees. The SoHI
(Appendix F) identifies that one (1) of these trees are associated with the local
listing of ‘sandstone retaining wall and trees’. However, the SoHI further identifies
that the other trees in the area are not part of the early 20 th century planting and
are therefore not heritage items.
The SoHI has determined that the affected trees are not the ones to which the
heritage significance is applied and further, despite the loss of trees, the remaining
tree, along with those planted as part of the Activity will continue to exist as
dominate streetscape elements. Once the proposed landscaping is undertaken to
partially replace the removed trees, the visual curtilage provided by the existing
trees will be reinstated.
Archaeological Report
The Archaeological report within Appendix G identifies that the REF Site is located
above the potential archaeological remains of a string of early to late nineteenthcentury properties. The proposed Activity will involve relatively minor sub-surface
24
JBA  10051
Barangaroo South

Hickson Road Alterations | August 2015
impacts and the road level will be raised rather than lowered. The stormwaterrelated works have only a very limited potential to impact on intact archaeological
remains, as the existing services would have disturbed or removed any remains
along their routes when they were installed. Therefore the Activity only has the
potential to have a minor impact on the potential archaeological remains and any
impacts would be localised.
Conclusion
The SoHI and archaeological report conclude that the Activity will not have any
substantial or unmanageable heritage impacts.
6.5.2 Mitigation Measures
In order to manage the potential impact to the archaeological remains within the
REF Site, a S139(4) notification should be made to the Heritage Division, Office of
Environment and Heritage, identifying exception type 1B, where ‘The excavation
or disturbance of land will have a minor impact on archaeological relics including
the testing of land to verify the existence of relics without destroying or removing
them’. This notification will be made at least 7 days prior to undertaking the
Activity.
The Activity should be monitored when they are in the vicinity potential
archaeological. The location and alignments of wall footings and any other
archaeological remains should be recorded on plan and by the surveyor where
possible if exposed. Artefacts relating to the 19th-century use of the area should
be collected if disturbed by the works.
A number of general management and mitigation measures are set out in Section
8 that address construction impacts.
6.6
Landscape and Visual
A Landscape and Design Statement has been prepared by Aspect + Oculus
(provided in Appendix D). Assessment and mitigation measures within the report
are summarised below.
6.6.1 Assessment
The proposed road and landscape works to Hickson Road will change and improve
the existing streetscape character and amenity.
The key upgrades to the streetscape include high quality granite paving, street tree
planting and furniture elements. The landscape works proposed, along with the
civil infrastructure improvements will integrate well with both the existing and new
development on either side of the road.
Despite the unavoidable removal of selected trees along Hickson Road as part of
this and other separate applications, the Activity will ensure a continuation of the
tree lined boulevard north of Napoleon Bridge through the retention of the high
value trees and planting of new trees that support the current character. The
planting of new street trees will partially offset the proposed removal of the
existing trees in the short term, and will eventually improve the streetscape
character in the long term.
6.6.2 Mitigation Measures
As part of the landscaping works associated with the Activity, trees will be
planted along Hickson Road to offset those that will be removed. As a result no
further mitigation measures are required.

Construction Air Quality
AECOM has prepared a letter addressing the potential air quality impacts of the
Activity (Appendix I). Assessment and mitigation measures within the report are
summarised below.
6.7.1 Assessment
A range of air quality investigations have been undertaken as part of the Project /
Development Applications submitted to the Department of Planning & Environment
and approved by Minister to date. These relate to:

Bulk Excavation and Basement Car Park (MP10_0023 - approved 2 November
2010);

Commercial Building C4 (MP10_0025 - approved 3 March 2011);

Commercial Building C5 (MP10_0227 - approved 24 April 2012);

Commercial Building C3 (MP11_0044 - approved 24 April 2012);

R8 R9 Residential Buildings (MP11_0002 - approved 28 June 2013); and

Concrete Batching Plan (SSD 5967 – approved 11 April 2014).
In the context of these approvals, Lend Lease has prepared, and regularly updates,
a detailed Air Quality and Odour Management Sub-Plan. The Sub-Plan details
prevention and management measures for air quality and odour issues associated
with construction works at Barangaroo South.
As the Activity will be undertaken by Lend Lease on behalf of the Barangaroo
Delivery Authority, it is appropriate that the same air quality and odour
management regime applied to the works on the Barangaroo South site be applied
to the Activity.
Dust can be generated from all types of construction activities involving soil,
including excavation, handling, loading and unloading and wind erosion of exposed
areas and stockpiles. Dust from the Activity will be managed in line with the
ECSMP.
The Activity would involve some diesel-powered plant and equipment. The
combustion of diesel fuel generates a range of pollutant emissions such as oxides
of nitrogen, carbon monoxide and particulate matter.
Certain contaminants have associated odours which can be liberated to air during
excavation and handling of spoil material. In the event that contaminated material
is encountered, it will be addressed in accordance with existing procedures,
including the unexpected find procedures, used at Barangaroo South and described
within the ECSMP.
It is not expected that the Activity or the equipment to be employed in executing
the Activity will have any substantive impact on air quality in the immediate
vicinity of the REF Site.
6.7.2
Mitigation Measures
During the Activity the mitigation measures (where relevant to the nature of
construction and ground conditions at the REF Site) set out in Section 5 of the Air
Quality and Odour Management Sub-Plan prepared for Barangaroo South will be
implemented. These include the following measures relevant to the Activity:

26
JBA  10051
Cover all loads departing the REF Site to minimise potential spillage / dust
generation.
Barangaroo South

Hickson Road Alterations | August 2015

Immediately clean up any spills.

Directly load spoil generated at the site into trucks for off-site disposal to
minimise the need for stockpiling.

Cover any stockpiled spoil material overnight during windy / rainy conditions,
unless spoil is damp, and provide bunding around the base.

Turn engines off while parked on site.

Regularly tune and maintain equipment, plant and machinery to minimise visible
smoke / emissions.
6.8
Construction Noise and Vibration
Works are proposed to be generally undertaken between the hours of 7.00am and
7.00pm Monday-Friday and between 7.00am and 5.00pm on Saturdays.
Occasional night works, and works on Sundays or public holidays, would be
required where dictated by authority requirements (such as road closures) or for
worker or public safety. This is consistent with the ECSMP (Appendix D).
A report on noise and vibration impacts associated with the Activity was prepared
by Wilkinson Murray (Appendix J). Assessment and mitigation measures within
the report are summarised below.
6.8.1 Assessment
Noise
The report identified 15 receptors that may be affected by construction noise as a
result of the construction. These receptors are mainly located in Millers Point and
are identified by Figure 2-1 in Appendix J.
Noise Management Levels based on the EPA Interim Construction Noise Guidelines
(ICNG) were determined for these identified receptors. Wilkinson Murray then
modelled various construction scenarios to determine the likely acoustic impact of
the Activity on the receptors.
A review of the results indicated that noise from the proposed construction works
associated with the Hickson Road realignment has the potential to exceed the
noise management levels during periods of works which are in close proximity to
the surrounding buildings. In particular this applies to some types of out of hours
works on Saturdays at the residences along Hickson Road.
The predicted noise levels generally comply with the Highly Noise Affected limit of
75dBA at these residences, with the exception of some hydraulic hammering
activities due to the requirement to add a + 5dB modifying factor.
At Napoleon on Kent some exceedances are predicted (particularly to the upper
floors) during use of hydraulic hammers where they are not shielded by the
Napoleon Street retaining wall or the Sussex Hotel. Due to the close proximity of
commercial receivers, including the Sussex Hotel, significant exceedances are
predicted of the Noise Management Levels when works are at their closest.
There are other construction works associated with Barangaroo and other projects
in the surrounding area that will be under various stages of construction when the
Hickson Road realignment works are scheduled (March 2016 – March 2017).
With the exception of the Sussex Hotel where the Realignment works occur
directly adjacent it is considered the other projects will dominate the noise levels
at the identified receivers due to both the greater scope of works and closer
proximity.
JBA  10051
27
Barangaroo South

Hickson Road Alterations | August 2015
Wilkinson Murray consider that the procedures and management measures that
are included in the existing site Environmental Management Plan are appropriate to
address any noise generated by the Hickson Road Realignment works and
accordingly no additional specific noise and vibration have been identified with the
exception that activities such as hydraulic hammering and saw cutting are
restricted to standard construction hours and are not scheduled for the extended
construction on Saturday afternoons. This recommendation is included in the
Mitigation Measures below.
Vibration
Vibratory impacts are predicted at two locations proximate to the REF Site,
namely the Sussex Hotel and the stairway adjacent to the Sussex Hotel. Certain
construction activities, such as dynamic compaction, have the potential to exceed
the levels established in the EPA guidance document Vibration a Technical
Guideline.
6.8.2 Mitigation Measures
Noise and vibration will be managed within a specific noise and vibration sub-plan
within the Activity ECSMP.
Activates such as hydraulic hammering and saw cutting of concrete will be
restricted to standard construction hours and will not be scheduled for the
extended construction on Saturday afternoons.
6.9
Crime Prevention
6.9.1 Assessment
From a crime prevention perspective, there are no evident concerns regarding antisocial and/or criminal behaviour, resulting from the Activity.
6.9.2 Mitigation Measures
The report suggests that anti-graffiti coatings should be applied to exposed
surfaces and that additional lighting within REF Site should be consistent with the
LED lighting being installed by Council.
6.10 Contamination
An assessment of the land contamination issues associated with the Activity has
been carried out by AECOM, with consideration of the RAP for Barangaroo South.
(Appendix M). Assessment and mitigation measures within the report are
summarised below.
6.10.1 Assessment
The Activity will not require the excavation of soil (other than base and sub-base
materials used in the construction of the existing road surface) from the REF Site.
All excavated material will be disposed offsite to a NSW EPA landfill in accordance
with the Department of Environment, Climate Change and Water, (2009) Waste
Classification Guidelines Part 1: Classifying Waste.
The AECOM assessment divided the REF Site into two portions:
28
JBA  10051

The ‘southern portion’, which extends along the eastern boundary of that part
of Barangaroo South known as Stage 1A (outside the NSW EPA Declaration
Area).

The ‘northern portion’, which extends up to and over the southern end of that
portion of the NSW EPA Declaration Area that is located within Hickson Road.
Barangaroo South

Hickson Road Alterations | August 2015
Within the northern portion concentrations of contaminants of potential concern
(CoPC) were recorded as being less than:

the risk based remediation criteria developed for the Stage 1A development
(i.e. the ‘Area A’ Site Specific Target Criteria [SSTCs] derived for areas outside
the ORWS basement [ORWS Amended RAP, AECOM, 2011]); and

the applicable NEPM (NEPC, 1999, as amended 2013) soil criteria for a
commercial/industrial land use. In addition, all BTEX, TPH and PAH
concentrations were reported at concentrations less than the laboratory limit of
reporting.
AECOM has therefore concluded that gasworks related contamination is not
located within this portion of the REF Site and that subsequently contaminated
materials are unlikely to be uncovered during the Activity. Importantly, the
northern end of the REF Site is also outside the extent of remediation as provided
for in the RAP demonstrating that remediation of the subject area is not
considered to be required to facilitate removal of the NSW EPA Declaration.
Within the southern portion:

the depth to bedrock at BH43 was observed to be 0.57 m bgl and 0.9 m bgl at
BH09. Borehole TBH09 was abandoned at a depth of 0.64 m bgl within a thick
asphalt layer;

gasworks related wastes were not identified in the fill or underling natural
materials. No other visual or olfactory signs of contamination were observed
during the sampling works; and

the CoPC concentrations reported in samples collected from BH09 and BH43
were less than both the risk based remediation criteria developed for removal of
the NSW EPA Declaration (the SSTCs for unsaturated soils as detailed in the
VMP/Block 4 RAP (AECOM, 2013b) and the applicable NEPM (NEPC, 1999, as
amended 2013) criteria for a commercial/industrial land use. Due to the nature
of the roadbase material identified at TBH09, the sample was not analysed.
The AECOM report states that any contamination that may be discovered in the
REF Site during the Activity is not likely to be associated with the EPA Declaration
Area and that the REF Site is likely to be suitable in its current state for the
proposed use and would not require remediation. Remediation of contamination
that may be identified is unlikely to be required because contamination typically
associated with fill and the presence of a concrete and/or asphalt over the entire
area is likely to prevent a complete exposure pathway between a future land user
(e.g. pedestrian) and the underlying contamination (if present).
Fill material is likely to be required to facilitate the Activity. The source of the
required material cannot be determined at this stage; however sandstone material
may be available from other projects within the CBD depending on construction
timing.
Fill material that is required to be imported from off site will be certified suitable
for this activity.
Imported fill material will be either VENM or it will be engineering material that has
been deemed suitable for use and will be imported subject to an exemption from
waste licencing issued in accordance with Clause 91 and 92 the Protection of the
Environment Operations (Waste) Regulation 2014.


Hickson Road Alterations | August 2015
6.10.2 Mitigation Measures
An unexpected finds protocol has been established within RAP and is outlined in
the ECSMP at Appendix D. This will be applied if contamination is identified during
the carrying out of works associated with the Activity.
While the Activity is unlikely to require excavation of material other than the
existing road pavement and road sub base materials, the unexpected finds
protocol will be undertaken to mitigate risks to human health in the unlikely event
that contamination is found to be present in association with the Activity.
6.11 Geotechnical
A geotechnical report was prepared by Coffey (Appendix L). Assessment and
mitigation measures within the report are summarised below.
6.11.1 Assessment
Coffey undertook a geotechnical investigation within the REF Site to determine the
suitability of the area for the Activity. Twelve boreholes were drilled at points
within the REF Site to inform the assessment. The subsurface conditions in the
area can be characterised as comprising mostly granular fill, overlying estuarine
sediments in some places or sandstone bedrock. The report concluded that the
REF Site is suitable for the Activity subject to measures being implemented as
outlined below.
6.11.2 Mitigation Measures
Following the assessment, Coffey made the following recommendations:

For areas featuring loose material:
–
Removal of a 200mm thick layer of material and replacing with a granular
material containing not more than 15% fines (silt and clay), and
–
compacting with a suitable roller or flat plate packer to 98% Standard Dry
Density
–
Site-won material may be suitable for this purpose, but would need to be
tested for confirmation of suitability. Such tests should include Atterberg
Limits tests, California Bearing Ratio (CBR) tests and Particle Size
Distribution (grading) tests.

Other areas should be proof-rolled prior to installation of the service.

Where invert level is below the water table, it may be necessary to install a
concrete blinding layer.

Dewatering may be necessary to carry out work at or below the invert level.

No specific surface preparation is recommended where the stormwater pipe
will be founded on rock.
6.12 Traffic and Transport
The Activity involves works to a public road, a summary of the anticipated
impacts on traffic and transport is included below. A Traffic and Transport report
has been prepared by ARUP and is included as Appendix N.
6.12.1 Assessment
Operational Traffic
The ease of traffic flow on urban roads is expressed as a ‘Level of Service’ (LoS)
LoS is expressed from ‘A’ to ‘F’, ‘A’ being free flowing and ‘F’ being heavily
30
JBA  10051
Barangaroo South

Hickson Road Alterations | August 2015
congested. For intersections in the Sydney CBD during commuter peak hours,
achieving a LOS E or better is generally considered acceptable.
The traffic modelling for the Hickson Road / Napoleon Street intersection indicates
that once the proposed road works are completed the intersection will operate
satisfactorily in both the AM and PM peak hours at a Level of Service D at the
completion of the Barangaroo Precinct including Headland Park and Barangaroo
Central. The traffic signals at this intersection will be coordinated with those at
the mid-block signalised crossing to be constructed at Sussex Street (under the
Sussex Street Bridge) to ensure traffic operates efficiently along Sussex Street.
Operational Movement and Design
The proposed layout of Hickson Road and Sussex Street has been designed in
accordance with relevant guidelines and standards, most notably the Austroads
Guide to Road Design and Australian Standards for Parking Facilities (AS 2890).
The vehicle swept path analysis undertaken by ARUP demonstrates that the
proposed design can satisfactorily accommodate the turning manoeuvres of the
above design vehicles. All movements are able to be executed independently
without crossing the path of another vehicle.
The review of the proposed road arrangements demonstrate that the configuration
is suitable for the intended movements and will provide adequate capacity for the
level of development completed during Stage 1A.
Construction Traffic
During the Activity, roads through the REF Site will remain partially open at all
times. Traffic around the REF site will be managed in line with the indicative
staging and frame work management measures outlined in Appendix N.
The works propose no changes to the number of traffic lanes on Hickson Road
and Sussex Street compared to the existing situation. A dedicated right turn bay
will be provided at all times during constructions for vehicles to travel from Sussex
Street into Napoleon Street. Therefore there will be no change to the carrying
capacity of the road network during the construction period relative to the current
situation.
To support the construction activity and maintain an acceptable level of traffic
operation, existing on-street parking bays will be temporarily suspended on
Hickson Road and Sussex Street. To support the construction works sections of
the Hickson Road and Sussex Street footpaths may be also be closed for
pedestrian access.
The report makes a range of recommendations to minimise the temporary impacts
of the works which are detailed in the Mitigation Measures below and will be used
to inform a more detailed traffic management plan (TMP) that will form part of the
Activity-specific CEMP. This will be finalised and agreed with all relevant roads
authorities before the commencement of the Activity.
Staging
As the Activity will coincide with the closure of George Street due to the
installation of light rail in Sydney CBD, allowance has been made for temporary
bus stops within the REF Site.
A temporary bus stop will be located north of the Napoleon Street/Hickson Road
intersection in both directions. The Activity will be managed (with the BDA) in
such a way as to allow for the continued operation of both northerly and southerly
bus stops throughout construction.
JBA  10051
31
Barangaroo South

Hickson Road Alterations | August 2015
6.12.2 Mitigation Measures
A Traffic Management Plan will be created to complement and be implemented
alongside the ESCMP. In order to minimise the impacts of the closure of the
footpaths for pedestrian access the following measures will be considered:

erection of hoardings to permit pedestrian movement adjacent to the
construction zone and separate pedestrians from construction vehicles;

installation of signage indicating recommended pedestrian routes;

maintaining access to either the western or eastern footpaths along Sussex
Street and/or Hickson Road throughout the construction period;

maintaining access to the temporary bus stops to be located north of napoleon
Street; and

maintaining safe crossings at the Kent Street/Margaret Street/ Napoleon Street
intersection and Sussex Street / Shelley Street intersection.
6.13 Construction Management
An ECSMP has been prepared by Lend Lease (Appendix D) this outlines the
framework and principles to guide the preparation of a detailed Construction
Environmental Management Plan (CEMP) by the appointed contractor prior to the
commencement of works.
6.13.1 Assessment
The ESCMP outlines high level site management guidelines for:

site management, including site establishment and construction methodology;

environmental management, including training responsibilities and contacts;

implementation, including management plans to mitigate any impacts; and

ongoing monitoring and review procedures.
These guidelines will establish the appropriate site management principles which,
when fully detailed as part of the ECSMP, will ensure that potential impacts
associated with the management of the demolition and construction activities do
not adversely impact upon the community.
A stakeholder engagement strategy has also been provided to outline consultation
methods and procedures which will be undertaken throughout the process. This
includes complaints handling and management procedures.
With the implementation of these above procedures and the development of a site
specific CEMP prepared by the selected contractor, all potential construction
impacts are expected to be managed.
6.13.2 Mitigation Measures
The Activity should be carried out in accordance with the ECSMP and the future
more detailed CEMP, to be prepared by the selected contractor. Works to utilities
services will be undertaken in accordance with the relevant utilities standards.
32
JBA  10051
Barangaroo South

Hickson Road Alterations | August 2015
6.14 Cumulative Environmental Impacts
In light of the assessment in Sections 5, it is considered that the Activity does not
give rise to any cumulative environmental impacts that cannot be appropriately
managed through the mitigation measures identified in Section 8.
Clause 228 of the EP&A Regulation requires the assessment of any cumulative
environmental impacts with other existing or likely future activities. Accordingly,
this REF has considered the cumulative impacts of all phases of the Activity.
The Activity will occur between March 2016 and March 2017 and will coincide
with works associated with the following projects:

construction of R1/R7 Residential Buildings;

Block 4 Remediation Works;

Block 5 Remediation Works;

Stage 1A Public Domain Works;

Stage 1C Remediation and Earthworks; and

works to Barangaroo Central – Waterfront Promenade.
The Activity can reasonably be expected to intensify activity in this locality. In this
regard, it should be noted that the works are to be undertaken by Lend Lease (on
behalf of the Barangaroo Delivery Authority), this means that every aspect of the
construction works at the bridge site can be managed seamlessly with, and in the
same manner as, activities on the Barangaroo site by Lend Lease on behalf of the
Barangaroo Delivery Authority.

7.0 Justification for the Proposal
In general, investment in projects can only be justified if the benefits of doing so
exceed the costs. Such an assessment must consider all costs and benefits, and
not simply those that can be easily quantified. As a result, the EP&A Act specifies
that such a justification must be made having regard to biophysical, economic and
social considerations and the principles of ecologically sustainable development.
This means that the decision on whether an activity can proceed or not needs to
be made in the full knowledge of its effects, both positive and negative, whether
those impacts can be quantified or not.
The Activity involves upgrade works to the existing Hickson Road, the stormwater
management infrastructure, and improvements to the public domain and services
along Hickson road. The assessment must therefore focus on the identification
and appraisal of the effects of the proposed change over the REF Site’s existing
condition.
Various components of the biophysical, social and economic environments have
been examined in this REF and are summarised below.
7.1
Social and Economic
The Activity will have a number of positive social and economic impacts,
including:

to improve and upgrade the functionality of the existing roads within the REF
Site;

to resolve existing ponding of water on Hickson Road in storm events,
including ponding that has the potential to flood the Sussex Hotel in a 100 year
ARI event by improving drainage in the area

to reduce future flood risk and manage the risk of sea level rise around
Barangaroo South;

to improve the amenity of the streetscape and its relationship with the
proposed permanent public domain works at Barangaroo South; and

responding to the raising of the ground level of the adjacent land at the
Barangaroo South development site by up to approximately 900mm through
increasing the level of the adjoining roads to better relate to the new ground
level at Barangaroo South.
The construction works have the potential to generate negative social and
economic impacts due to disturbances to the local visual and acoustic amenity and
the LoS of the local road network during the Activity. The Activity will also have a
temporary impact on State and locally listed heritage items, as outlined in
Appendix F, Appendix G and Section 5.5.
Construction impacts will be temporary in nature, limited to the construction
duration, and can be largely managed through the Mitigation Measures set out in
Section 8.
Longer term impacts, such as those impacts to the identified heritage items, have
been assessed within this REF and will not have a significant adverse effect
provided that the mitigation measures set out in Section 8 are followed.
34
JBA  10051
Barangaroo South
7.2

Hickson Road Alterations | August 2015
Biophysical
The environmental impact assessment of the Activity has demonstrated that there
will be no adverse biophysical impacts. While the works require the removal of
eighteen (19) trees, this impact is necessary in order to enable the Activity and to
avoid causing the trees to become a hazard in the future if left in place. As part of
the landscaping works associated with the Activity replacement trees will be
planted within the REF Site. This replacement planting of American Tulip Trees,
Urbanite Ash, and Cabbage‐tree Palms will offset the loss of the existing trees
from the REF Site (see Section 5.6). The Activity is therefore unlikely to result in
adverse impacts on any sensitive ecosystems and environments.
7.3
Ecologically Sustainable Development
The EP&A Regulation lists 4 principles of ecologically sustainable development to
be considered in assessing a project. They are:

the precautionary principle;

intergenerational equity;

conservation of biological diversity and ecological integrity; and

improved valuation and pricing of environmental resources.
An analysis of these principles follows.
Precautionary Principle
The precautionary principle is utilised when uncertainty exists about potential
environmental impacts. It provides that if there are threats of serious or irreversible
environmental damage, lack of full scientific certainty should not be used as a
reason for postponing measures to prevent environmental degradation. The
precautionary principle requires careful evaluation of potential environmental
impacts in order to avoid, wherever practicable, serious or irreversible damage to
the environment.
This REF has not identified any serious threat of irreversible damage to the
environment and therefore the precautionary principle is not relevant to the
proposal.
Intergenerational Equity
Inter-generational equity is concerned with ensuring that the health, diversity and
productivity of the environment are maintained or enhanced for the benefit of
future generations. The Activity has been designed to benefit both the existing
and future generations by:

minimising the impact on the heritage listed items for future generations to
appreciate and enjoy by avoiding impacts to listed street trees adjacent to the
Sussex Hotel, and improving the public domain thereby allowing greater
appreciation of other heritage items in the vicinity of the REF Site;

implementing safeguards and management measures to protect environmental
values; and

improving the public domain in the area by reducing the local flood risk and
improving the relationship between the road surface within the REF Site and
the Barangaroo South precinct.
The Activity has integrated short and long-term social, financial and environmental
considerations so that any foreseeable impacts are not left to be addressed by
future generations.
JBA  10051
35
Barangaroo South

Hickson Road Alterations | August 2015
Conservation of Biological Diversity and Ecological Integrity
The principle of biological diversity upholds that the conservation of biological
diversity and ecological integrity should be a fundamental consideration.
The Activity would not have any significant effect on the biological diversity and
ecological integrity of the study area.
Improved Valuation, Pricing and Incentive Mechanisms
The principles of improved valuation and pricing of environmental resources
requires consideration of all environmental resources that may be affected by a
proposal, including air, water, land and living things. Mitigation measures for
avoiding, reusing, recycling and managing waste during construction and operation
would be implemented to ensure resources are used responsibly in the first
instance.

8.0 Summary of Impacts
The Activity is subject to assessment under Part 5 of the EP&A Act. This review
of environmental factors (REF) has examined, and taken into account to the fullest
extent possible, all matters affecting or likely to affect the environment by reason
of the proposed activity.
The Activity, as described in the REF, best meets the stated objectives but will
result in some minor impacts to existing street trees and heritage items. The
implementation of the mitigation measures detailed in Section 8 of this REF and as
recommended by the various specialist reports (refer to Appendices) will serve to
ameliorate or minimise these expected impacts.
The Activity will also result in a number of positive impacts, including:

to improve and upgrade the functionality of the existing roads within the REF
Site;

to resolve existing ponding of water on Hickson Road in storm events,
including ponding that has the potential to flood the Sussex Hotel in a 100 year
ARI event by improving drainage in the area; and

to improve the amenity of the streetscape and its relationship with the
proposed permanent public domain works at Barangaroo South.
Short-term negative impacts during construction can be acceptable managed
through the application of appropriate management measures. These are set out in
in the ECSMP and the CEMP.
On balance, the Activity is considered to be justified.
The environmental impacts associated with the Activity are not likely to be
significant and the proposal will not impact on any matters of national
environmental significance.
Having regard to the above, it is concluded that the Activity is not likely to
significantly affect the environment within the meaning of section 112 of the
EP&A Act.

9.0 Mitigation Measures
The mitigation measures outlined in this document and summarised in this section,
form part of the proposal and will be incorporated into the detailed design and
implemented during the construction phases associated with the pedestrian bridge.
The implementation of these safeguards and measures will ensure that the
proposed works associated with the Activity will not have a significant impact on
the environment.
This REF has been prepared in accordance with the plans and supporting
information described in Table 5 below.

loose material or when disposing of waste products or during any other
activities likely to pollute drains or watercourses.
2.11 Signage at key intersections approaching the site should be installed to
inform drivers of the construction and the detour routes that are in place.
2.12 The final extent of any construction zone will be subject to an application
and approval by the road authority, which will also include the submission
of traffic control plans to be prepared by an RMS accredited contractor.
2.13 Measures to mitigate temporary footpath closures should include:

Erection of hoardings to permit pedestrian movement adjacent to the
construction zone and separate pedestrians from construction vehicles

Installation of signage indicating recommended pedestrian routes;

maintaining access to the temporary bus stops to be located north of
napoleon Street;

Maintaining access to either the western or eastern footpaths along
Sussex Street, as well as the Napoleon Street eastern footpath,
throughout the construction period
3. Excavation and Construction
3.1 A copy of the approved and plans, specifications and documentation shall
be kept on site at all times and shall be available for perusal by any officer
of Council.
3.2 Where possible, site hoardings are to be installed around demolition and
construction areas to prevent public access to the site.
3.3 During construction, should the site turn out to be heavily contaminated,
contaminated soil would have to be handled as contaminated waste, any
on-site spot remediation that may be required can be undertaken as
Category 2 Remediation under SEPP 55.
3.4 Works to utilities services will be undertaken in accordance with the
relevant utilities standards.
4. Tree Protection
4.1 Each tree to be retained should be fenced off to the extent of the Tree
Protection Zone excluding all activity unless otherwise indicated in the
report. The fencing is to exclude storage of materials, site sheds,
machinery, run off (eg concrete, or chemical treatments), the movement
of pedestrian or vehicular traffic, the temporary, location of services, eg
trenches, pits or canals.
4.2 No works should be performed within the fenced area without specific
consideration given. This includes mechanical scouring of existing
vegetation and changes of soil levels (either the addition or removal).
4.3 Where access is required adjacent to a tree eg along a driveway trunks
and branches will require protection
4.4 For large significant trees fencing should be 1.8m in height of cyclone
chainmesh or similar. Other vegetation can be isolated using star pickets
and orange parra-webbing8.
4.5 Site Signage on the fencing reminds workers of specific reasons for the
fencing – for example:

‘This fencing is not to be moved’.

‘This Tree Protection Zone is to isolate vegetation from the building
process’.

No equipment or materials are to enter or be stored within the fenced
area and no chemicals or run off enter this protected zone.

Should fencing need to be moved for any reason first contact …Site
Manager on 9999 9999 or Arborist on 0417 022 692’.
4.6 Where a tree trunk is likely to be knocked (eg site access along a
driveway) it must be protected from possible damage. Protection material

may be hessian, carpet, underfelt (or similar breathable material) with
timber planks attached with wire or rope, encircling the materials (not into
trunk).
Protection material should cover from the base of the tree to 2m (or to a
level that is likely to be damaged by passing equipment, branch protection
also may be required.
Where access or works within TPZ are required soil surface protection
must be installed i.e. a platform (constructed of steel material or
timber/rumble boards capable of supporting and distributing the weight
over a layer of mulch) and geotextile fabric
To accommodate works some pruning might be required.
All pruning should be performed by a Qualified Tree Surgeon to ensure
pruning is to AS 4373- 1996 ‘Australian Standards for Pruning Amenity
Trees, see Appendix D). (If greater than 10% council approval may be
necessary).
The TPZ should ideally be maintained as least as well as was previously
experienced by the tree. Where there are significant changes to the trees
normal water supply such as diversion of previous run off or in extended
periods of dry, watering should take place. (Check by digging down 1015cm to ensure water is wetting the root zone and not running off).
The demolition process should occur well outside the tree protection zone
and ideally be greater than the drip zone or 6m from any trees to be
retained. Where this is not possible, a protection layer of mulch (100mm
of Eucalyptus wood mulch or similar) should be laid over the area of
encroachment. Where vehicular access is required across the mulch layer,
further root protection should be constructed with steel material or timber
capable of supporting vehicles and distributing their weight. Pruning of
foliage may be required.
Within the drip zone of a tree to be retained, demolition should be
performed by hand to ensure that the tree is not damaged.
Where works or site access is proposed within the canopy of a tree,
careful consideration of the appropriate protection is required.
Works such and scaffolding installation or where tall machinery is to pass,
can damage foliage of trees on the site or overhanging from adjacent
land.
Pruning should be undertaken to prevent damage and this should be
performed to AS4373. Note: Where trees overhang from adjacent land,
Council and tree owner approval is required.
Trunks and branches are important for tree structural support and
anchorage, nutrient transport and nutrient storage. Damage to trunk and
branches are usually caused by works too close to a tree or during site
access for other areas. Damage to the trunk or branches can affect tree
stability and allow pathogen or disease to enter.
In most cases the whole tree and TPZ should be isolated from the works
process by Tree Protection fencing. Where access is required near a tree
the trunk and branches should be wrapped and boarded for protection
from damage.
It is important to minimise soil compaction by isolating the tree and most
of the tree roots zone from site works or significant changes Tree decline
is often not evident for several years.
Where works are required within the TPZ, soil surface protection methods
must be undertaken. This involves adding mulch and rumble boards.
Weight distribution over the area with the use of rumble boards or steel
plates over mulch over geotextile fabric.
Where works are required within the SRZ it is important to minimise
damage and avoid damage to roots providing tree anchorage.
All works within SRZ should be performed using hand tools and to
specific arboricultural specifications and preferably with your AQF Level 5
arborist on site to ensure that no roots of 20mm or greater are damaged.
Barangaroo South

Hickson Road Alterations | August 2015
4.24 When heavy equipment passes over them or materials are stored within
their growing area. Installation of services, paving and landscaping within
the TPZ must be carefully consider likely damaging tree roots and loss of
air and oxygen in the soil.
4.25 All tree works recommended in this report should comply with the
Australian Standard for Pruning of Amenity Trees AS4373-2007, and be
performed by a suitably qualified and experienced tree surgeon, preferably
with membership of a recognised organisation. Tree Contractors
Association (TCA) or National Arborists Association of Australia (NAAA).
4.26 All equipment used should be cleaned before use and between trees with
either 10% bleach 90% water or 70 % Metho 30% water.
4.27 Where a tree is suspected of being diseased the wood should be disposed
of with care and not used for mulch.
5. Heritage
5.1 Any heritage relics or sites discovered during construction shall be
reported to the Barangaroo Delivery Authority. Any proposal to disturb
any suspected relics or heritage sites may require consultation with the
NSW Heritage Office.
5.2 Any evidence of Aboriginal relics discovered during construction shall be
reported to the Barangaroo Delivery Authority. Any proposal to disturb
suspected relics or Aboriginal heritage site may require consultation with
OEH. All work is to cease on site until the relevant permit is received or
advice is provided by the Barangaroo Delivery Authority that work can
recommence.
5.3 a S139(4) notification should be made to the Heritage Division, Office of
Environment & Heritage, identifying exception type 1B, where ‘The
excavation or disturbance of land will have a minor impact on
archaeological relics including the testing of land to verify the existence of
relics without destroying or removing them’. This report should
accompany the application.
6. Air Quality
6.1 Section 5 of the Air Quality and Odour Management Sub-Plan prepared
for Barangaroo South must be implemented throughout construction.
7. Noise and Vibration
7.1 The Noise and Vibration Management Sub-Plan prepared for Barangaroo
South must be implemented throughout construction.
7.2 Activities such as hydraulic hammering and saw cutting are restricted to
standard construction hours and are not scheduled for the extended
construction on Saturday afternoons
8. Geotech
8.1 For areas featuring loose material:
 Removal of a 200mm thick layer of material and replacing with a
granular material containing not more than 15% fines (silt and clay),
and
 compacting with a suitable roller or flat plate packer to 98%
Standard Dry Density
 Site-won material may be suitable for this purpose, but would need
to be tested for confirmation of suitability. Such tests should include
Atterberg Limits tests, California Bearing Ratio (CBR) tests and
Particle Size Distribution (grading) tests.
8.2 Other areas should be proof-rolled prior to installation of the service.
8.3 Where invert level is below the water table, it may be necessary to install
a concrete blinding layer.
8.4 Dewatering may be necessary to carry out work at or below the invert
level.

8.5 No specific surface preparation is recommended where the stormwater
pipe will be founded on rock.
9. Water Quality
9.1 Section 5 of the Water Quality Management Sub-Plan prepared for
Barangaroo South must be implemented throughout construction.
9.2 An Erosion and Sediment Control Plan must be developed prior to
construction, outlining specific requirements to ensure protection of the
surrounding environment. The plan should include the following measures:
 Protect stormwater kerb inlets with filter fabrics and sediment control
‘socks’.
 Keep the work zone clean at all times.
 Classify material to be excavated during the services investigation
stage. Directly load spoil generated at the site into trucks for off-site
disposal to prevent runoff from excavated material entering the
stormwater system.
 Ensure no on-site storage of fuel, hydraulic oil or chemicals during
the works. Refuel machinery using mini-tankers.
 Ensure spill kits are available at all times.
 Keep trucks in the work zone on the existing roadway surface at all
times. Cover loads and check wheels prior to exiting the site to
ensure no dirt is tracked onto Sussex Street.
 Ensure all erosion and sediment controls are in place prior to any
work taking place and checked daily.
10.
Waste Management
10.1 All waste generated by the Activity, shall be beneficially reused, recycled
or directed to a waste facility lawfully permitted to accept the materials in
accordance with the DECCW’s “Waste Classification Guidelines (2008)”
and the Protection of the Environment Operations Act 1997.
10.2 Where available, recyclable site and construction waste are to be recycled
in accordance with the NSW Government’s “Waste Reduction and
Purchasing Policy (WRAPP guidelines)”. Waste oil will be sent to
approved recyclers.
10.3 The type and volume of all waste materials (e.g. excavation material,
green waste, bricks, concrete, timber, plasterboard and metals) will be
estimated prior to demolition and construction with the destination
specified either for on-site re-use or recycling, or off-site re-use or
recycling and as a last resort disposal at a licensed waste facility.
10.4 No burning or burying of wastes is permitted on site.
10.5 Non-recyclable waste and containers are to be regularly collected and
disposed of at a licensed landfill or other licensed disposal sites in the
area.
10.6 Waste management practices for the Proposal are to follow the resource
management hierarchy principles embodied in the Waste Avoidance and
Resource Recovery Act 2001. These practices include: avoid unnecessary
resource consumption; recover resources (including reuse, reprocessing,
recycling and energy recovery); and dispose (as a last resort).
11.
Contamination
11.1 If any contaminated materials or hazardous substances (for example,
asbestos, polychlorinated biphenyls, synthetic mineral fibre, lead dusts,
paint containing lead and ozone depleting substances) are encountered
during demolition and construction then safe work method statements
and appropriate documented practices are to be implemented.
42
JBA  10051
Barangaroo South

Hickson Road Alterations | August 2015
11.2 Contamination of the site during construction works is to be avoided.
11.3 Any contaminated materials or hazardous substances are to be classified
first and then stored, transported and disposed of in accordance with
OEH requirements at an OEH licensed waste facility.
11.4 Should any new information come to light during demolition or
construction works which has the potential to alter previous conclusions
about site contamination then the Managing Contractor must be
immediately notified and works must cease. Works must not recommence
on site until the site is remediated in accordance with an approved
Remedial Action Plan, and a Validation and Monitoring Report together
with a notice of completion of remediation pursuant to clause 18 of State
Environmental Planning Policy No 55 – Remediation of Land has been
submitted to and approved by OEH.
11.5 Asbestos removal and management in NSW is regulated under the
Occupational Health and Safety Act 2000 and Occupational Health and
Safety Regulation 2001. The handling of asbestos and asbestos work
must be carried out in accordance with the following documents
published by the NOHS Commission in August 1988, as in force from
time to time (clause 259):

“Guide to the Control of Asbestos Hazards in Buildings and
Structures [NOHSC: 3002 (1988)]”; and

“Code of Practice for the Safe Removal of Asbestos [NOHSC: 2002
(1988)]”.
11.6 The Regulation requires licensed contractors to contact WorkCover NSW
of each bonded asbestos removal project of 10m2 or more.
11.7 Any contaminated material (i.e. lead paint) is to be classified first and
then stored, transported and disposed of in accordance with OEH
requirements at an OEH licensed waste facility
11.8 Excavations within the subject areas will be visually inspected by a
qualified environmental engineer/scientist;
11.9 If the subsurface soils are significantly different to those described in
Section 4.0 (i.e. based on visual and olfactory observations), validation
soil sampling of the excavation base and walls will be conducted. If
required, the validation soil samples will be collected as follows:
11.10 The soil analytical results will be compared to:
- for excavations within the Declaration Area - the unsaturated SSTC
(VMP/Block 4 RAP [AECOM 2013b]); or
- for excavations outside the Declaration Area:
- the NEPM (NEPC, 1999, as amended 2013) soil criteria for a
commercial/industrial land use; or
- complete a site specific risk assessment could be undertaken. It is
noted that remediation of contamination that may be identified in the
subject area is unlikely to be required based on a site specific risk
assessment because contamination typically associated with fill and
the presence of a concrete and/or asphalt over the entire area is likely
to prevent a complete exposure pathway between a future land user
(e.g. pedestrian) and the underlying contamination (if present).
11.11 Based on the assessment of the above soil validation results, undertake
additional remediation and validation works (as required); and
11.12 Materials used to backfill the trenches will be tested and validated to
ensure they meet either the applicable SSTCs (for inside the Declaration
Area) or the NEPM (NEPC, 1999, as amended 2013) soil criteria for a
commercial/industrial land use (for outside the Declaration Area).
11.13 Wall validation samples will be collected at 10 m lineal metre intervals in
material identified to be the most impacted (either by visual observations
of field screening of samples using a Photoionisation Detector); and
11.14 Base validation samples will be collected at 10 m lineal metres along the
base of the trench.
11.15 Imported fill will be certified before being introduced to the REF Site.

12.1 You must enter into an agreement with Sydney Water in the form of the
enclosed Deed.
12.2 You must engage your current or another authorised Water Servicing
Coordinator (Coordinator) to manage the design and construction of the
required works to Sydney Water’s standards and procedures. Before you
engage another Coordinator you must write and tell Sydney Water.
For a list of authorised Coordinators either visit
www.sydneywater.com.au > Plumbing, building & developing >
Developing > Providers > Lists or call 13 20 92. Coordinators will give
you a quote or information about costs for services/ works including
Sydney Water costs
The Coordinator generally will be the single point of contact between you
and Sydney Water. They can answer most questions you might have
about our process and charges
12.3 After you engage a Coordinator, you and your accredited Developer
Infrastructure Providers (Providers) will need to sign and lodge both copies
of the enclosed Deed with your nominated Coordinator. After Sydney
Water has signed the documents, one copy will be returned to the
Coordinator.
The Deed sets out for this project:
–
your responsibilities;
–
Sydney Water’s responsibilities; and
–
the Provider’s responsibilities.
You must do all the things that we ask you to do in that Deed.
If Sydney Water does not receive the signed Deed for our signing by 11
September2015 you will need to re-apply (and pay another application
fee).
Note: The Coordinator must be fully authorised by us for the whole time
of the Deed
12.4 If you need to enter a neighbouring property, you must have the written
permission of the relevant property owners and tenants. You must use
Sydney Water’s Permission to Enter form(s) for this. You can get copies
of these forms from your Coordinator or the Sydney Water website. Your
Coordinator can also negotiate on your behalf. Please make sure that you
address all the items on the form(s) including payment of compensation
and whether there are other ways of designing and constructing that
could avoid or reduce their impacts. You will be responsible for all costs
of mediation involved in resolving any disputes. Please allow enough time
for entry issues to be resolved
12.5 You must not start work on the existing water main or the proposed
adjustment until Sydney Water advises your Coordinator. This includes
the placement of any temporary pipework. Before you can do this
pipework, you must engage your Coordinator to lodge an application that
must include appropriate temporary pipework detail as well as the design
of the proposed adjustment.
Sydney Water will then assess both designs and advise your Coordinator
when they are approved and of any conditions to be met before pipe
placement. One condition will be:
44
JBA  10051


Hickson Road Alterations | August 2015
–
the lodgement of an unconditional security bond from an
acceptable financial institution that will cover Sydney Water’s risk
for this work; and
–
your acceptance in writing to bonding conditions that we will
provide in another agreement.
If any work on our assets is carried out without that advice or final
approval, Sydney Water will take action to have work on the site
stopped. We will apply the provisions of Section 45 of the Sydney
Water Act 1994.
12.6 Construction of these works will require you to pay project management,
survey, design and construction costs directly to your Providers.
Additional costs payable to Sydney Water may include:
–
water main shutdown and disinfection;
–
connection of new water mains to Sydney Water system(s);
–
design and construction audit fees;
–
contract administration, Operations Area Charge & Customer
Redress prior to project finalisation;
–
creation or alteration of easements etc.;
–
water usage charges where water has been supplied for building
activity purposes prior to disinfection of a newly constructed
water main.
Note: Payment for any Goods and Services (including Customer
Redress) provided by Sydney Water will be required prior to the release
of the Bank Guarantee or CashBond.
Your Coordinator can tell you about these costs.
12.7 Sydney Water is currently investigating the request for Sydney Water to
contribute towards the adjustment/renewal work. If a contribution is
applicable the Sydney Water (Urban Growth) Procurement Guidelines
must be followed.
The actual amount of funding will be determined when the design plans
are finalised. Construction commencement will not be permitted until a
business case for the budget allocation has been approved by Sydney
Water.
12.8 Any variation submitted to Sydney Water for approval during the design
and/or construction stages of the works must include the associated
cost and details of the variation. Sydney Water will review the variation
and advise of the outcome.
As soon as a variation occurs, Sydney Water is required to be notified
in writing within a reasonable period of time of the estimated cost of the
variation, nature of variation and description on events and history.
All variations, where there is a contribution by Sydney Water must
follow the Sydney Water (Urban Growth) Procurement Guidelines.
12.9 Because this work involves construction on a “live” Sydney Water water
main, you must also:
–
Have your Building Plans are approved prior to temporary
pipework and excavation,
–
Submit your temporary pipework design (if required) with your
permanent wastewater deviation design for approval,
–
Accept in writing to bonding conditions that will be provided in
the Bond Agreement,
–
Submit your Bond and signed Bond Agreement,
–
Submit the Construction Commencement Notice for construction
of the temporary pipework,

After we receive a copy of the successful tender for the work, we can
calculate the amount of this bond. We will then send you that other
agreement which will tell you this amount. You must lodge the bond and
the completed agreement with Sydney Water before you start
constructing the work.
The bond will be released after you have completed the construction of
the works. (This includes lodgement of Work As Constructed plans and
production and/or recreation of documentation and reports and
completion of all the excavation and landscaping works needed for the
total project.)
In addition, the following specific conditions apply:
