Wyndham Ridge Estate, Residential Subdivision – Statement of Environmental Effects

1.0 Introduction
Hardie Greta Pty Ltd submit this Statement of Environmental Effects (SEE) for the development of land at Greta.
The site subject of this SEE is known as Lot 2 in Deposited Plan (DP) 1151267 and Lot 2 in Deposited Plan (DP)
808354. A locality plan showing the site and surrounding lands is provided in Figure 1.

The development involves subdivision to create two hundred and forty eight (248) allotments, two drainage
reserves, one allotment for open space, as well as earthworks and infrastructure works associated with each
stage of the development.

1.1 Site Context
Greta is located in the Cessnock Local Government Area (LGA). The West and Wyndham Streets Greta Urban
Release Area is located in the suburb of Greta and contains approximately 28.5ha of Low Density Residential,
8.51 hectares of Large Lot Residential Land and 7.7ha of Environmental Conservation land.

The site is surrounded by Large Lot Residential land to the south-east, rural land to the north and east and
residential land to the south-west. The Hunter River Regional Reserve is located to the north east of the site.

The desired future character of the West Street, Greta Urban Release Area is a mix of residential lot sizes that
reflect the constraints and opportunities of the site and complement the existing settlement pattern. On the
eastern side of the release area, minimum lot sizes will be 2,000m². On the western side of the release area,
there will be a mix of lot sizes ranging from 600m² to 2,000m².

The development area of the site is gently undulating topography with elevations on the site rising from RL 62
metres on the southern boundary to a maximum height of RL108 metres towards the northern boundary.

The land was the subject of extensive rezoning investigations. At the Cessnock City Council meeting on 19th
February 2014 the Planning Proposal to rezone the site was supported to make the amendment to the Cessnock
Local Environmental Plan 2011 pursuant to the Environmental Planning and Assessment Act.

2.0 Proposal
The proposal subject of this SEE involves the subdivision of the site to create two hundred and forty eight (248)
allotments, two drainage reserves, one allotment for open space, as well as earthworks and infrastructure works
associated with each stage of the development.

A Concept Plan of Subdivision is illustrated in Figure 2 and Annexure 1.

Wyndham Ridge Estate, Residential Subdivision – Statement of Environmental Effects

The lot layout/staging plan illustrate:

Two hundred and forty eight (248) proposed residential allotments of variable size.

The lots shown in stage 1 are located on the part of the site that is zoned R5 Large Lot Residential and in
accordance with the provisions of the CLEP 2011 the minimum lot size is 2,000m2.

The lots shown in stages 2 & 3 are located on the part of the site that is zoned R2 Low Density Residential. In
accordance with the provisions of the CLEP 2011 there is a mixture of minimum lot sizes of 600m2, 1,200m2 and
2,000m2.

Two drainage allotments are provided and dedicated to Council. One in the south west corner and the other in
the north west corner of the R2 Low Density Residential zone.

One proposed open space lot to be dedicated to Council in the south west portion of the R2 Low Density
Residential zone.

The proposal includes clearing of all vegetation (if necessary) contained within the area where the 248 residential
allotments, roads and associated services will be located. The proposal also includes earthworks and
infrastructure works necessary for the development of the land.

The constructed roads, drainage allotments and open space lot will be dedicated to Council.

2.1 Staging
The subdivision is to be constructed in three stages as illustrated in Figure 2 and Appendix 1.

Stage 1 involves the creation of 34 lots, the construction of West Street, construction of the south western
detention basin and associated infrastructure.

Stage 2 involves the creation of 118 lots and associated infrastructure.

Stage 3 involves the creation of 96 lots, construction of the north western detention basin and associated
infrastructure. Timing of the release of stages will be subject to market demand.

3.0 Consultations
A pre-DA meeting was held with Council staff on 7th March 2014. Minutes of this meeting are contained in
Appendix 2.

The SEE and DA has considered items outlined in the pre-DA meeting.

Post the pre-DA meeting further correspondence between the proponent and Council resulted in the final road
and pavements widths as adopted and shown in the SEE.

4.0 Planning and Statutory Considerations
4.1 Lower Hunter Regional Strategy
The LHRS 2006 provides a regional context to the need for accommodation population growth within the Lower
Hunter Region. The strategy discusses opportunities for urban release areas, infill development, centres and
corridors, and employment generating lands. The LHRS 2006 (p. 27) identifies that between 2006 and 2031 the
Maitland LGA is projected to accommodate an additional 26,500 dwellings. It is anticipated that the majority of
dwellings (21,500) will be contained within new urban release areas, while centres (2,000) and urban infill (3,000)
development will comprise the remaining 5,000 dwellings.

The LHRS identifies the subject site as a proposed urban area.

Following extensive investigations, the subject site has been incorporated into Cessnock Council’s City Wide
Settlement Strategy. Cessnock City Council at its meeting on 19th February 2014 resolved to forward a site
specific Planning Proposal to the Department of Planning and Infrastructure so that the site can rezoned as an
amendment to the Cessnock Local Environmental Plan 2011.

The proposed development described in this application is consistent with the LHRS as it contributes towards
meeting the demands for the supply of residential housing within the Lower Hunter.

4.2 Cessnock City Wide Settlement Strategy
The City Wide Settlement Strategy (CWSS) was adopted by Council on 15 September 2010. The CWSS sets out
strategic directions that informed the preparation of the CLEP 2011 and implemented a number of the outcomes
and actions arising from the LHRS. A fundamental action from the CWSS is the need to contain the urban
footprint of the Cessnock LGA to that identified in the LHRS and the CWSS.

The DA and SEE demonstrates the consistency of the proposed development of the site to the CWSS and CLEP
2011. The proposal for subdivision will be consistent with the objectives of the CWSS.

4.3 Environmental Planning & Assessment Act 1979
Section 79C Evaluation -Potential Matters for Consideration

In determining a development application, a consent authority is to take into consideration such of the following
matters as are of relevance to the development the subject of the development application:

(a) the provisions of:

   i.    any environmental planning instrument, and
  ii.    any proposed instrument that is or has been the subject of public consultation under this Act and that has
         been notified to the consent authority (unless the Director-General has notified the consent authority that
         the making of the proposed instrument has been deferred indefinitely or has not been approved), and
  iii.   any development control plan, and
 iv.     any planning agreement that has been entered into under section 93F, or any draft planning agreement
         that a developer has offered to enter into under section 93F, and
  v.     the regulations (to the extent that they prescribe matters for the purposes of this paragraph), and
 vi.     any coastal zone management plan (within the meaning of the Coastal Protection Act 1979), that apply to
         the land to which the development application relates,

(b) the likely impacts of that development, including environmental impacts on both the natural and built
environments, and social and economic impacts in the locality,
(c) the suitability of the site for the development,
(d) any submissions made in accordance with this Act or the regulations,
(e) the public interest.

Section 91 Integrated Development

Integrated development is development which, as well as development consent, requires one or more approvals
under certain sections of the following State legislation:

This development is considered to be an integrated development due to the subject site being partly located
within a bushfire prone area. The DA will be referred to the Rural Fire Service by Council. A Bushfire Threat
Assessment has been undertaken and is discussed in Section 5.7 of this SEE.

The development will also be integrated development under the Water Management Act 2000, with respect to
the 2 bridge crossings within West Street.

4.4 State Environmental Planning Policy (SEPP)
State Environmental Planning Policy No. 44 – Koala Habitat Protection

The policy aims to encourage the conservation and management of areas of natural vegetation that provide
habitat for Koalas. Koalas are classified as “vulnerable and rare” species under the provisions of the Threatened
Species Conservation Act 1997.

The ecological assessment prepared for the site identified that the land does not constitute ‘Potential Koala
Habitat’ under the provisions of the SEPP. In addition, there were no sightings of Koalas utilising the site during
the ecological surveys. No further provisions of this Policy apply to the proposed development in this instance.

State Environmental Planning Policy No. 55 – Remediation of Land

The objective of SEPP 55 – Remediation of Land is to promote the remediation of contaminated land for the
purpose of reducing risk of harm to human health or any other aspect of the environment.

Clause 7 of the SEPP relates to development applications. That is, a consent authority must firstly consider
whether a site is contaminated. If the land is contaminated, the consent authority must be satisfied that the land
is suitable in its contaminated state, or it will be suitable after remediation, for the proposed development.

A phase 2 Contamination Assessment was undertaken in conjunction with the Planning Proposal for the subject
site. The assessment confirmed the subject site as being suitable for residential purposes.

State Environmental Planning Policy Infrastructure 2007 (ISEPP)

The following ISEPP provisions have been considered in relation to the proposal:

Clause 104 relates to traffic generation development. A traffic assessment has been prepared and is further
discussed within section 5.5 – Traffic and Access. The development will be referred to the Roads and Maritime
Services (RMS).

4.5 Cessnock Local Environmental Plan 2011
CLEP 2011 aims to make local environmental planning provisions for land in Cessnock in accordance with the
relevant standard environmental planning instrument under section 33A of the EP&A Act. The proposed
development is consistent with the Aims of the Plan under Section 1.2 of the CLEP 2011 which secures the
environmental, social and economic balance for the future of the LGA. The following provides commentary on the
relevant Parts within CLEP 2011.

Cessnock City Council at its meeting on 19th February 2014 resolved to forward a site specific Planning
Proposal to the Department of Planning and Infrastructure so that the site can rezoned as an amendment to the
Cessnock Local Environmental Plan 2011.

Wyndham Ridge Estate, Residential Subdivision – Statement of Environmental Effects
Part 2 ‐Land Use Zones
Figure 3 shows the zones adopted by Council of the site. The objectives of the relevant zones are as follows:

Zone R2 Low Density Residential

       To provide for the housing needs of the community within a low density residential environment.

       To enable other land uses that provide facilities or services to meet the day to day needs of residents.

Zone R5 Large Lot Residential

       To provide residential housing in a rural setting while preserving, and minimising impacts on,
        environmentally sensitive locations and scenic quality.

       To ensure that large residential lots do not hinder the proper and orderly development of urban areas in
        the future.

       To ensure that development in the area does not unreasonably increase the demand for public services
        or public facilities.

       To minimise conflict between land uses within this zone and land uses within adjoining zones.

The proposed subdivision fulfils the objectives of both the R2 & R5 zones. The subdivision layout is adequately
sized and positioned to allow development of varying lot sizes within the relevant zone. The subdivision will
provide additional housing opportunities for both the local community and the wider region.

Supporting services and infrastructure will be provided throughout the development.

Wyndham Ridge Estate, Residential Subdivision – Statement of Environmental Effects
Part 4 ‐Principal development standards
4.1 Minimum subdivision lot size
The proposed subdivision has minimum lot sizes that are consistent with Section 4.1 of CLEP 2011.

Figure 4 shows the minimum lot size map adopted by Council. There is a mixture of minimum lot sizes of
600m2, 1,200m2 and 2,000m2. Lot sizes across the site ranges from 600m2 to 3,094m2. The subdivision provides
a range of varying lots sizes.

The location of the proposed lot boundaries are generally consistent with the concept development plan
considered by Council throughout the rezoning process.

Part 5 Miscellaneous Provisions
5.9 Preservation of trees or vegetation
Removal of vegetation on site requires the consent from the Council. This application seeks approval for the
clearing of land as described in section 2.0 – Proposal. This matter is further discussed is section 5.2.

Part 6 Urban release areas
The subject site is classified as an Urban Release Area. In accordance with Part 6 of the CLEP 2011
“satisfactory arrangements” are to be made for the provision of designated State public infrastructure before the
subdivision of land in an urban release area to satisfy needs that arise from development on the land.

The landowner of the site has commenced discussions with the Department of Planning and Infrastructure
(DoPI) in order to achieve the “satisfactory arrangements” under Part 6 of LEP 2011.

Further information regarding the nature of the “satisfactory arrangements” will be forwarded to Council during
the DA assessment process.

6.2 Public utility infrastructure
Council is to be satisfied, prior to consent, that any public utility infrastructure that is essential for the proposed
development is available, or that adequate arrangements have been made to make that infrastructure available
when it is required.

Consultation has been undertaken with Hunter Water Corporation in relation to the provision of reticulated water
and sewer infrastructure to the development area. This matter is further addressed in the Servicing Strategy
discussed within section 5.13.

Electricity supply and telecommunications will be provided to the development in accordance with the
requirements of the relevant service authorities as the development progresses.

6.3 Development Control Plan
This clause requires that a Development Control Plan (DCP) is to be prepared prior to any development consent
being granted for development on land within an urban release area. The matters to be addressed in the DCP
are prescribed in the clause. The DCP requirements are addressed within the local development controls in
section 4.6.

Part 7 Additional local provisions
7.1 Acid Sulphate Soils
The development site is not identified on Council’s Acid Sulphate Soil Map as being located on land potentially
containing Acid Sulphate Soil’s.

7.2 Earthworks
The development site will require earthworks associated with the subdivision of land including the construction of
roads, storm water and utility infrastructure.

7.3 Flood Planning
The development site is not affected by any 1:100 year flood events.

4.6 Cessnock Development Control Plan 2010
The CDCP 2010 identifies general controls across the LGA and specific controls in certain localities. Within the
CDCP 2010 a number of sections will apply to the proposal, including:

•        Part C Chapter 2 Flora and Fauna Guidelines and Waste Management;

                          of totally on the subject site. The disposal of effluent utilising pump-outs for new lots is
                          unacceptable.

                          e) For subdivisions proposing to create 5 or more allotments of 2.0 hectares or below in           N/A
                          size, or where any boundary of the proposed subdivision is within 2.0 kilometres of an
                          existing sewage reticulation system, Council may require the provision of a reticulated
                          sewerage treatment system. The only circumstances where this standard should be varied
                          is on sites already substantially cleared of native vegetation, where soils are highly suitable
                          for effluent disposal and where they are not located near a watercourse, wetland or other
                          environmentally sensitive area. In these cases, a detailed investigation into the disposal of
                          effluent on-site, including any long-term and / or cumulative effects will be required. Such
                          investigation shall be generally in accordance with the requirements of the NSW State

5.0 Planning and Design
5.1 Subdivision Design Considerations
Urban Design Principles
The proposed subdivision fulfils the principles of good design through a layout achieving connectivity while
responding to site constraints and opportunities. The Concept Plan of Subdivision is shown in Figure 2 and
Annexure 1 demonstrates the subdivision being designed to create a safe subdivision.

The layout is generally consistent with the plan of subdivision that was considered by Council in conjunction with
the rezoning of the lands, and was used to inform the zone boundaries and minimum lot size boundaries for the
site. The layout is in accordance with the site specific Development Control Plan.

Lot Size and Dimensions
The proposed subdivision provides a varied lot range, in terms of type and size.

The development will consist of allotments with lot sizes ranging between 600m2 to 3,094m2 in size. Allotments
generally front relatively straight sections of proposed streets and are regular shaped with similar primary street
frontage to rear boundary ratios. All allotments have been designed to provide sufficient access to services, solar
access, sitting of buildings, access to the each allotment within the constraints of the site.

Solar Access & Energy Efficiency
The internal road network within the proposed subdivision is orientated primarily in either a north-south or east-
west direction. The orientation of the street determines the amount of solar access received. A combination of
aspect and orientation will determine the solar access for each allotment. The allotments have an area to suitably
site a building envelope with sufficient solar access.

Crime Prevention through Environmental Design
Effective designs of subdivisions can reduce community fear, as well as opportunities for crime. The proposed
subdivision complies with the principles of CPTED and best practice guidelines with design details as described
in the following sub-sections.

Pedestrian and Cycle Routes
The subdivision does not create opportunities for crime risk or community fear by providing places for
offenders to hide or entrap victims. Pathways will link to the open space areas and off road cycleways that
link the development to the town of Greta creating and open feel. Similarly, opportunities for natural
surveillance are afforded from nearby residences and from vehicles using the road network.

Natural Surveillance
The objectives of natural surveillance are to encourage the passive observation of spaces from surrounding
buildings and land uses and to further improve surveillance through increased legitimate use. To ensure that the
objectives of natural surveillance are met, clear sightlines have been provided between public (streets and
pathways) and private spaces.

At the construction stage of the residential subdivision, natural surveillance should be reinforced by focusing on
orientation of buildings and strategic use of windows, balconies, entrances, permeable fencing and street design.

Landscaping
A Landscape Concept Plan and Report for the proposed subdivision has been prepared by Moir Landscape
Architecture and is contained in Appendix 9. The Landscape Concept Plan will ensure that the subdivision is
attractive and encourages legitimate use of public spaces.

Lighting
Lighting of public places such as public streets and pedestrian areas will meet the relevant Australian
Standards.

Solar Access and Energy Efficiency
The CDCP 2010 requires subdivisions to consider solar access in the design of lots. The lot orientation of the
subdivision will enable effective solar access and energy efficiency of future dwellings.

5.2 Ecology

The site has been the subject of a several ecological studies completed to support the rezoning of the land and
provision of a biodiversity offset package, including HSO (2006), EcoLogical Australia (2011), and Firebird
ecoSultants Pty Ltd (2013). A biodiversity offset package for the proposal has been implemented at the land
rezoning stage. In consultation with the NSW Office of Environment and Heritage (OEH) and Cessnock City
Council, a planning agreement under section 93F of the EP&A Act ensures the provision of biodiversity offsets to
compensate for the loss of biodiversity which will occur as a result of the proposed development.

The NSW Minister for the Environment has formally agreed to accept the 297 hectare off-site offset, being Lot 9,
Lot 102 and Lot 207 DP753817 for addition into Wollemi National Park and the provision of $26,000 to cover
reserve establishment costs. The on-site offset, being the 7.9 hectare E2 Environmental Conservation zoned
land, will be protected by a positive covenant under Section 88B of the Conveyancing Act 1919 and the land
managed for conservation purposes through a Vegetation Management Plan. It has been demonstrated that the
biodiversity offset package will ensure that regional biodiversity values are maintained and that it is acceptable to
meet OEH requirements to permit the whole of the proposed residential development and the inevitable clearing
of the site. The planning agreement and proposed offset contributions will protect areas containing like-for-like
habitat for Central Hunter Ironbark – Spotted Gum – Grey Box Forest EEC and threatened species impacted
upon by the proposed development.

The planning agreement legally establishes the manner and timing in which the biodiversity offsets will occur. It
will also achieve the protection of the biodiversity significance of land both on-site and off-site in perpetuity to
offset the potential impacts arising from the development.

Based on the survey effort and results of these previous studies, and in consultation with Cessnock Council
ecologist Firebird ecoSultants Pty Ltd undertook a report to recognise the relevant requirements of the
Environmental Planning and Assessment Act 1979 (EP&A Act) and the Threatened Species Conservation Act
1995 (TSC Act) by undertaking assessments of significance (7-part tests) to support a development application
for the residential subdivision and development. The report is contained in Appendix 3.

The report concluded the impact on the environment from the residential development is not significant and is
unlikely to place any viable local populations of threatened species at risk of extinction. The report
recommended the following recommendations:

       The proposed planning agreement is enacted to facilitate the biodiversity offset package;
       Construction and development activities are contained within the residential zoned areas;
       The land zoned E2 Environmental Conservation is fenced;
       Landscaping / habitat revegetation within the site to use local endemic species characteristic of the
        endangered ecological communities present;
       Hydrological controls (e.g. Water Sensitive Urban Design principles) are implemented to maintain the quality
        and quantity of pre-development water flows into downstream areas;
       Ecologist present during hollow-bearing/habitat tree removal.

5.3 Stormwater and water quality

Fisher Consulting Engineers has prepared a Stormwater Drainage Strategy for the proposed subdivision and is
contained in is contained in Appendix 4.

The stormwater drainage strategy addresses stormwater quantity and quality requirements, and flood levels for
the proposed development.

Stormwater Flow Management (stormwater runoff quantity and quality)

The strategy for management of stormwater runoff from the development as depicted in the report comprises:
Wyndham Ridge Estate, Residential Subdivision – Statement of Environmental Effects
      Capture of stormwater from lot and road reserve areas by a conventional pit and pipe drainage network
       located in the street or in interallotment drainage easements where required.
      Conveyance of captured stormwater within the drainage pipe network to gross pollutant traps (GPT’s) for
       primary treatment prior to discharge into the proposed combined detention basin and constructed
       wetland.
      The detention basins will provide attenuation of developed stormwater flowrates to existing flowrate
       conditions.
      The constructed wetland will provide secondary/tertiary treatment and polishing of the stormwater runoff
       prior to discharge downstream.
      Discharge from the outlet of the constructed wetlands will be conveyed over land to the existing
       unnamed watercourse.

The proposed stormwater management measures will be located within drainage reserves and dedicated to
Council consistent with other developments within the Cessnock LGA.

Flooding

In 2010 WMAwater engaged by Cessnock City Council and Maitland Council released a report titled the Hunter
River, Branxton to Green Rocks Flood Study, known as Flood Study 2010. The subject sites developments
footprint ranges from R.L 62m AHD to R.L 108m, and the 100 year (1% AEP) flood level is R.L 27m AHD.
Therefore the development is not affected by flooding from the Hunter River, and no further investigation was
considered necessary for the intent of the strategy.

5.4 NSW Office of Water Creek Crossings

Fisher Consulting Engineers has prepared a bridge crossing report of pre and post development hydraulic
conditions for two proposed bridges located in the existing unformed road reserve of West Street, downstream of
the proposed Wyndham Ridge subdivision. This report has been prepared to support a Controlled Activities
Approval application to the NSW Department of Water. The report is contained in is contained in Appendix 5.

5.5 Traffic and Access

SECA solution prepared a Traffic Impact Statement for the site and the Statement is contained in Appendix
6. The Statement considered traffic data collected in conjunction with field observations and obtained
background data from the Roads and Maritime Service (RMS) for the locality.

Overall the Statement concludes that the additional traffic movements generate by the development will have an
acceptable impact upon the local road network.

The Traffic Impact Statement for the site was reviewed by Cessnock City Council in conjunction with the Planning
Proposal and Voluntary Planning Agreement (VPA) Infrastructure Contributions. This review resulted in the
following external road works being included and funded in the Local Area Monetary Contributions for Traffic and
Drainage:
      West Street – Reconstruction from High Street to Branxton Street, Widen & reconstruct road with kerb
        and drainage;
      Bus Bay – Water Street to entry driveway, Construct 1 indented bus stop with all-weather shelter
      Bus Bays within proposed subdivision, 2 bus shelters
      West Street – Shared off road footpath/cycleway, West Street from High Street to Branxton Street (200m)
        and West Street from Branxton Street to entry driveway (800m)
      West Street – Drainage lines

No other road or drainage work upgrades external to the sites boundaries are required.

5.6 West Street Engineering Report

Fisher Consulting Engineers prepared an Engineering Report for the proposed road works within the unformed
road reserve of West Street Greta, to support a proposed Development Application for a residential subdivision.
The Engineering Report addresses general engineering options in the unformed West Street road reserve that
are likely to be required to support the proposed residential subdivision. The report is contained in Appendix 7.

West and Branxton Street Intersection
The existing intersection of West Street and Branxton Street will require upgrading in conjunction with the
proposed extension of West Street to the proposed subdivision. The report shows a concept upgrade of the
intersection with a vehicle priority change giving main priority to vehicles travelling along West Street. It is
proposed that vehicles travelling on Branxton Street will have secondary priority. This arrangement is consistent
with other existing roads which are running parallel to West Street on its south eastern side.

West Street road layout
Council have advised that the unformed portion of West Street is to be constructed with an 11.0m wide kerb face
to kerb face carriageway. It is proposed to provide a 2.0m wide verge on the north western side (LHS) of the
11.0m wide road and a 4.5m wide verge on the south eastern side (RHS) of the 11.0m wide road. The 4.5m
wide verge is to contain a 2.0m wide combined pedestrian footpath and cycleway. It is considered that a narrow
footway adjacent to rural property, which is not the subject of this development application, is appropriate to
assist the constructed roadway’s batter extent to be maintained within the existing road reserve.

To assist in minimising the required works at the two watercourse crossing locations, it is proposed to narrow the
constructed roadway to 8.0m kerb face to kerb face, and to narrow the LHS and RHS verges. Narrowing of the
roadway and verges will assist in minimising the required crossing structures which will, in turn, assist in
minimising the impact on the watercourse’s existing environment. It is proposed to maintain the 8.0m roadway
formation between the two watercourse crossing locations to maintain consistency for vehicular movements
along West Street. It is considered that the narrowing of the pavement at the two watercourse crossing
locations, and for the roadway in between, to be appropriate as there should not be any permitted vehicular
parking in this vicinity, and cyclists are catered for via the proposed combined pedestrian footpath and cycleway.

Stormwater Conveyance in West Street
A traditional pit and pipe system is proposed for the carriageway within the unformed road reserve of West
Street. The pit and pipe system will capture and convey stormwater flows from the road carriageway and
discharge the flow into the existing watercourse.

It is proposed that two bridge structures will be constructed at the location of the two watercourse crossings to
convey the watercourse flow through the West Street road reserve. The bridge structures will generally enable
the existing features of the watercourse to be maintained.
