Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 60
Review of Environmental Factors
Early works
Subject to approval of the proposal, Roads and Maritime may undertake an early
package of works comprising the construction of an earth platform to the north of the
existing Mona Vale Road carriageway between Tumburra Street and the location of
the proposed fauna land bridge.
This would comprise:
Site clearance and installation of environmental controls
Relocation/adjustment of high voltage and communications utilities
Placement of fill material in layers
Placement of topsoil and seeding.
Construction of the earth platform would use about 85,000 m3 of material which
would be sourced from the Mona Vale Road East Upgrade Project.
Construction staging
To minimise impacts to traffic and to ensure safety risks to workers are minimised, it
is anticipated that the proposal would be constructed in stages. The preliminary
construction staging strategy comprises four stages as follows:
Stage 1: Between chainages 0–1000, carry out widening on the southern side of
the existing carriageway while keeping the traffic on the existing carriageway;
carry out intersection upgrade work at Kimbriki Road
Stage 2: Construct the new (deviated) section of carriageway from
chainage 1000 to Tumburra Street off line from the existing carriageway
Stage 3: Construct the local access road along Harvey Road including
intersection upgrade work at Powder Works Road. This would provide an
alternative access to the Wirreanda Valley area while Stage 4 is being
constructed
Stage 4: Widening on both sides from Tumburra Street to Powder Works Road.
The scope of works for each stage would be subject to review and potential revision
during detailed design and pre-construction planning.
Work methodology
Construction sequence
The work methodology for the proposal would be refined during the detailed design
phase. Construction activities would be guided by a Construction Environmental
Management Plan (CEMP) to ensure works are located within the specified works
areas and implement all safeguards as described in this REF, and any subsequent
measures included as a result of submissions.
The indicative construction sequence for the proposal is as follows:
Issue community update about upcoming roadworks
Establish environmental exclusion zones including the limits of clearing
Install temporary erosion, sedimentation and drainage controls
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 61
Review of Environmental Factors
Establish site compound and stockpile areas
Establish construction phase traffic control, including temporary traffic signs,
safety barriers, line marking changes and similar
Remove property fences and erect temporary security fence as required
Mark trees requiring removal and carry out inspection by suitably qualified
ecologists
Clearing of vegetation
Stripping and stockpiling of topsoil by grader, excavators and trucks
Progressive relocation, adjustment and/or protection of all affected utilities,
services and signage to suit construction staging requirements.
Bulk earthworks (cut/fill operation) by grader, excavator, haul trucks
Drainage works by excavator and haul trucks
Stabilise exposed areas
Recycle suitable excavated material and incorporate unsuitable material in
earthworks within the road reserve where possible
Install Select Material Zone (SMZ) using grader, excavator, haul trucks and roller
compactors
Sprayed seal on top of SMZ
Place lean mix or asphalt sub base using paver and truck
Sprayed seal on top of lean mix concrete paving
Construct retaining walls and other structures
Prepare existing pavement for new lane surfaces using grading and milling
machine
Form new kerbs, gutters, medians and other structures using kerb machine,
concrete truck and hand tools
Construct asphaltic concrete pavement and associated works using paver and
roller
Construct footpath paving using concrete trucks and hand tools
Install temporary pavement as needed to tie-in to existing road for traffic switch,
as required
Install safety barriers where needed
Implement traffic switch to facilitate staging of works, as required
Implement final property adjustments including ancillary works inside private
property and the final boundary fence
Landscape using backhoe, trucks and hand tools
New line marking, lighting and sign posting
Site clean-up and disposal of all surplus waste materials
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 62
Review of Environmental Factors
Remove construction traffic management and open new works to traffic.
Construction of rock cuttings
The indicative rock cutting construction sequence for the proposal is as follows:
Establish environmental exclusion zones including the limits of clearing
Install temporary erosion, sedimentation and drainage controls
Establish stockpile areas
Establish construction phase traffic control, including temporary traffic signs,
safety barriers, line marking changes and similar
Remove property fences and erect temporary security fence as required
Mark trees requiring removal and carry out inspection by suitably qualified
ecologists
Clearing of vegetation
Install protection screening where required
Stripping and stockpiling of topsoil using machinery such as grader and
excavators. Topsoil material to be removed by trucks as generated and taken to
a stockpile site
Excavation of the rock cutting by one of two possible methods:
Rock to be pre-cut in a grid pattern using an excavator mounted rock cutting
blade. Blocks of rock pulled out from the rock face one at a time using an
excavator mounted ripping claw and hauled by hauling trucks to the stockpile
site
Rock ripped using an excavator or similar vehicle. Material to be ripped in
layers until it reaches designed level. There is one rock cutting to be
excavated using this method which requires approximately 250 metres of cut
in length and around 10 metres in height. Material to be removed by trucks as
generated and either directly reused on site
Construct pavement once design level are achieved
Stabilise exposed areas
Site clean-up and disposal of all surplus waste materials
Remove construction traffic management and open new works to traffic.
Drainage works
The construction sequence for drainage works would generally involve:
Access tracks – all tracks would be within the construction footprint, and have a
layer of clean fill to create a stabilised surface and installation of sediment and
erosion controls
Pre-construction culvert inspections
Installation of erosion and sediment control facilities to minimise the impact on
receiving water quality
Construction of diversions to direct flows around the existing culverts
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 63
Review of Environmental Factors
Excavation of culvert base slabs
Construction of the culvert foundations using granular material, piers or piles,
depending on the subsoil condition
Pouring of culvert concrete base slab
Installation of box culvert precast U-units on base
Placement of fill over units to form the base course for the road foundation
Infilling of the diversion channel with compacted fill and re-establishment of
drainage flows into the new culverts
Where necessary, scour protection would be provided upstream and/or
downstream of each culvert
Stabilise exposed areas and revegetate
Site clean-up and disposal of all surplus waste materials.
Construction hours and duration
Construction is expected to take about 30 months to complete, weather permitting. At
the time of preparation of this REF, funding for construction of the project had yet to
be confirmed and identification of a specific commencement date is therefore not
possible. However, construction is expected to follow that of the Mona Vale Road
East Upgrade Project.
The workforce would comprise up to 50 personnel during peak periods.
Construction of the proposal would be undertaken primarily during standard working
hours in accordance with the Interim Construction Noise Guideline as follows:
Monday to Friday: 7am to 6pm
Saturday: 8am to 1pm
Sundays and public holidays: no work.
It is anticipated that some work would need to occur outside of the standard working
hours to minimise traffic impacts, including utility adjustments, asphalting and line
marking. Work outside of standard hours (if required) would be in accordance with
Environmental Noise Management Manual Practice Note vii – Roadworks Outside of
Normal Working Hours (Roads and Traffic Authority, 2001) the Interim Construction
Noise Guideline (Department of Environment and Climate Change, 2009) and the
safeguards contained in this REF. This would include notifying the local community of
any works planned to be undertaken outside standard construction hours.
Plant and equipment
Construction of the proposal would be undertaken using standard road project
construction techniques. Typical plant and equipment that may be used during
construction includes items identified in Table 3-4.

Earthworks
The proposal would require numerous sections of cut and fill along most of the
alignment. Fill would be required for the earth platform described in Section 3.3.1,
behind retaining walls, and at various locations for the length of the proposal.
Current estimates are that about 138,300 cubic metres of cut material would be
generated from the proposal. About 169,400 cubic metres of fill would be required
and would preferentially be sourced from suitable cut material from the proposal.
Current estimates identify about 31,100 cubic metres of additional fill would be
required. The Harvey Road extension would generate about 37,600 cubic metres of
cut material and would require about 26,300 cubic metres of fill material.
Other excavated materials would likely include milled asphalt, select material and
topsoil.
An assessment of the earthworks volumes required for both Mona Vale Road East
and Mona Vale Road West identified that there would be a surplus of material
generated from Mona Vale East. The assessment found that the rock material won
from cuts in Mona Vale East would be suitable for use as select material, reducing
the amount of fill required in Mona Vale West. The preliminary assessment has not
considered topsoil stripping or replacement.

Source and quantity of materials
Materials would be sourced locally where possible, with the majority of materials to
be sourced from the Sydney region.
Table 3-7 shows the estimated quantities of particular materials which would be
required by the proposal.

Light duty pavement base (base for pathways, etc) 1880
Concrete footpath 1880
Water for construction would be sourced from available hydrants in the area. The
required quantities of water are not yet known, however the use of material such as
ready mix concrete (required for pavement and kerbs) would reduce the amount of
water required during construction. Water would also be required for compaction of
pavement layers, such as select layers to adjust the moisture content, and for dust
suppression.
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 67
Review of Environmental Factors
Surplus material that is not able to be used on-site as part of the proposal would be
reused or disposed of in the following order of priority:
Transfer to an approved Roads and Maritime temporary stockpile site for future
use during projects or routine maintenance
Transfer to a Roads and Maritime approved site for reuse on concurrent
private/local government project (with appropriate approvals as required).
Disposal at an approved materials recycling or waste disposal facility
As otherwise provided for by the relevant waste legislation.
The process for management of excess material would be detailed in a Resource
and Waste Management Plan (RWMP) that would form part of the CEMP.
Traffic management and access
Vehicle movements
Maintaining traffic flow during construction is a key consideration for construction
traffic planning for the proposal. It is expected that a maximum of 50 construction
vehicles per day during the peak construction period would be required. The majority
of these vehicles would undertake trips either predominantly or entirely along the
Mona Vale Road corridor and local roads being upgraded as part of the proposal.
Traffic management
A Traffic Management Plan (TMP) would be prepared in accordance with the
document Traffic Control at Worksites (Roads and Traffic Authority, 2010) and Roads
and Maritime Specification G10–Control of Traffic.
The TMP would provide details of traffic switches and the traffic management
measures to be implemented during construction to ensure that traffic flow on the
surrounding network is maintained where possible. The TMP would also ensure the
safe separation of workers on site from vehicles on Mona Vale Road.
The TMP would detail specific haulage routes that construction traffic would follow
throughout the construction phase.
At this stage of planning, it is intended to maintain two traffic lanes (one each way)
during construction, however, a reduced speed limit may be introduced for the
duration of works.
Access
While the location of the site compounds and stockpile locations is yet to be
confirmed, based on the preliminary locations selected, it is considered likely that the
majority of construction related traffic would be contained within the local area.
All property accesses would be maintained throughout construction.
Ancillary facilities
At the present stage of planning, it is proposed to use the same site office location for
the Mona Vale Road East Upgrade project. This would be used for worker amenities,
project related office facilities, storage of equipment.
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 68
Review of Environmental Factors
Alternative or additional sites may be identified during detailed design or at a later
stage during construction. The selection of any additional or alternative site
compounds and temporary stockpile sites would also be considered against the site
selection criteria detailed in Table 3-8. Should these sites be located outside of the
existing proposal construction impact area, additional environmental assessment
would be undertaken.
Table 3-8 Selection criteria for stockpile and compound sites
Selection criteria
Location Located within the project study area or directly adjacent to the
proposal
Stockpiling sites are not to be located on slopes with a gradient
greater than 2:1 horizontal to vertical.
Locate other compound sites on relatively level ground.
Services Locate site offices where they can be easily serviced with electricity
and potable water.
All ancillary sites are to have direct and safe access to the road.
Environmental Wherever possible, sites are to be located above the 1 in 100 year
flood level.
Locate facility more than 50 metres from watercourses*
No substantial vegetation clearing. Ancillary sites are to be located
on land of existing low conservation significance for flora and fauna.
Wherever possible, sites are to be located and designed to satisfy
noise and vibration management levels, relevant to the noise
catchment area, and vibration goals at the sensitive receiver (or
building, in the case of vibration). If noise management levels or
vibration goals cannot be met, feasible and reasonable mitigation
measures, the restriction of hours of operation and/or negotiated
agreements with affected parties would be considered.
Heritage Locate on sites that have a low likelihood of having Aboriginal or non-
Aboriginal heritage significance and/or potential.
* Refers to the working footprint of the facility. The land on which the site is located may
encompass or may extend within the 50 metre buffer to the watercourse.
Public utility adjustments
The section of Mona Vale Road in the study area includes utilities for Sydney Water,
Ausgrid, Jemena, Optus and Telstra. Utilities are located both overhead on poles
(electrical and communications) and underground (sewer, potable water,
communications and gas).
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 69
Review of Environmental Factors
Electricity
Ausgrid has low-voltage and street lighting cables (415 V), distribution cables (11 kV)
and a transmission feeder (assumed to be 33 kV) that extends along the length of the
Mona Vale Road on both sides of the existing alignment. The clearance to the
transmission feeder is low at many locations along the alignment, and the road
upgrade could have direct impacts on the feeder.
Water and sewer
Sydney Water has a rising sewer main running the length of this section of Mona
Vale Road, on the northern side of the existing carriageway.
A section of 100 millimetre diameter potable water pipeline (about 10–20 metres
long) extends along the road corridor from McCarrs Creek Road to Ch 75.
Gas
Jemena has a 250 millimetre diameter secondary gas main running through the
proposed alignment. The main extends below the existing pavement from Ch 0–150,
where it crosses to the northern side of the existing alignment. It then exits the
corridor to the north at about Ch 400 before returning to the northern side of the
existing alignment at Ch 2190 (Tumburra Street). The main then crosses to the
southern side of the existing alignment at Ch 2270 and follows the southern side to
the end of the study area. The road upgrade would have some impacts on the
secondary main, where adjustment works may be required
Telecommunications
The Telstra network consists of overhead and underground assets along Mona Vale
Road. The Telstra cable is located underground along the northern side of the
existing alignment from Ch 0–405. The cable then crosses the existing alignment
overhead and continues on shared poles until Ch 1185 where it again crosses the
alignment overhead and exits the alignment to the north. The cable re-enters the
alignment underground on the northern side at Addison Road and remains on this
side until the end of the study area.
The Telstra cable appears to serve local properties only and does not appear to be a
trunk main between exchanges. Relocation should therefore be relatively
inexpensive and undertaken quickly.
Many overhead services would require relocation to underground given the proximity
of the poles to the proposed alignment. Existing underground conduits are likely to
require local adjustment to suit the revised road geometry and to provide connection
to the relocated overhead services. Any changes to conduits may also require
relocation of pits/pillars.
The Optus network consists of aerial coaxial, aerial optic fibre and underground optic
fibre cables. Some relocation / protection of Optus network assets is also likely to be
required.
Property acquisition
Property acquisitions would be required as detailed in Table 3-9. Any requirement to
lease areas would be determined during detailed design.

Review of Environmental Factors
The areas of land required from Ku-ring-Gai Chase National Park and Garigal
National Park have been acquired through the revocation process under the National
Parks and Wildlife Act 1974 (NPW Act) (refer Section 4.3.5).
Final acquisitions required would be confirmed through detailed design in
consultation with landowners. All property valuations and acquisitions would be
carried out in accordance with the Roads and Maritime Services Land Acquisition
Information Guide (Roads and Maritime Services, 2014b) and the Land Acquisition
(Just Terms Compensation) Act 1991.

Review of Environmental Factors
Statutory and planning framework
State Environmental Planning Policies
State Environmental Planning Policy (Infrastructure) 2007
State Environmental Planning Policy (Infrastructure) 2007 (ISEPP) aims to facilitate
the effective delivery of infrastructure across the State. Clause 94 of the ISEPP
permits development on any land for the purpose of a road or road infrastructure
facilities to be carried out by or on behalf of a public authority without consent.
As the proposal is for a road and road infrastructure facilities, and is to be carried out
by Roads and Maritime, it can be assessed under Part 5 of the EP&A Act.
Development consent from Northern Beaches Council is not required.
Part of the proposal is located on land within Ku-ring-Gai Chase National Park and
Garigal National Park which comprises land reserved under the NPW Act. Roads and
Maritime has acquired the subject areas of land following a revocation process under
the NPW Act.
The proposal does not affect land or development regulated by State Environmental
Planning Policy No. 14–Coastal Wetlands, State Environmental Planning Policy
No. 26–Littoral Rainforests, State Environmental Planning Policy (State and Regional
Development) 2011 or State Environmental Planning Policy (Major Development)
2005.
Part 2 of the ISEPP contains provisions for public authorities to consult with local
councils and other public authorities prior to the commencement of certain types of
development. Consultation, including consultation as required by ISEPP (where
applicable) is discussed in Section 5 of this REF.
State Environmental Planning Policy 44 Koala Habitat
Protection
State Environmental Planning Policy No.44–Koala Habitat Protection (SEPP 44)
aims to encourage the conservation and management of areas of natural vegetation
that provide habitat for koalas to ensure a permanent free living population over their
present range and reverse the current trend of koala population decline. SEPP 44
applies to a range of LGAs including Northern Beaches.
Part 2 of SEPP 44 regulates impact on koala habitats. While it strictly only applies to
proposals being assessed under Part 4 of the EP&A Act, as a matter of practice
Roads and Maritime considers SEPP 44 as part of the Part 5 assessment process.
Local Environmental Plans
The proposal is located within the Northern Beaches LGA which was established on
12 May 2016 through the amalgamation of Pittwater, Warringah and Manly Councils.
The proposal sits within the former Pittwater and Warringah LGAs and the respective
planning instruments still have effect pending gazettal of the Northern Beaches Local
Environmental Plan.
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 74
Review of Environmental Factors
Pittwater Local Environmental Plan 2014
Development within the former Pittwater LGA is regulated under the Pittwater Local
Environmental Plan 2014 (Pittwater LEP 2014). The proposal is primarily located
within the SP2 Infrastructure (Classified Road) zone, but would also occur in the
following other zones:
RU2 Rural Landscape
RE1 Public Recreation
R2 Low Density Residential
The proposal is consistent with the objectives of the SP2 Infrastructure zone, which
are as follows:
To provide for infrastructure and related uses
To prevent development that is not compatible with or that may detract from the
provision of infrastructure.
With the exception of the RE1 Public Recreation zone, development for the purposes
of roads is permitted with development consent in the above zones. Within the RE1
Public Recreation zone, roads are prohibited. However, as noted in Section 4.1.1, the
ISEPP removes consent requirements and prohibitions that would otherwise apply to
the proposal.
Warringah Local Environmental Plan 2011
Development within the former Warringah LGA is regulated under the Warringah
Local Environmental Plan 2011 (Warringah LEP).
The existing Mona Vale Road is zoned SP2 Infrastructure. The objectives of this
zone are:
To provide for infrastructure and related uses
To prevent development that is not compatible with or that may detract from the
provision of infrastructure.
The proposal would also impact on land within the following zones:
E1 National Parks and Reserves
E3 Environmental Management
RE1 Public Recreation
Clause 94 of the ISEPP permits development on any land for the purpose of a road
or road infrastructure facilities to be carried out by or on behalf of a public authority
without consent.
Other relevant NSW legislation
Protection of the Environment Operations Act 1997
The Protection of the Environment Operations Act 1997 (POEO Act) regulates
certain activities with respect to pollution impacts (such as air, water and noise
pollution). Part 3.2 of the POEO Act requires an Environment Protection Licence
(EPL) for scheduled development work and for carrying out scheduled activities.
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 75
Review of Environmental Factors
Item 35 of Schedule 1 to the POEO Act applies to road construction, meaning the
construction, widening or rerouting of roads. Any activity to which the definition
applies is declared to be a scheduled activity if it results in the existence of four or
more traffic lanes (other than bicycle lanes or lanes used for entry or exit) for at least:
(a) Where the road is classified, or proposed to be classified as a freeway or
tollway under the Roads Act 1993:
i. 1 kilometre of their length in the metropolitan area, or
ii. 5 kilometres of their length in any other area.
(b) Where the road is classified, or proposed to be classified, as a main road (but
not a freeway or tollway under the Roads Act 1993:
i. 3 kilometres of their length in the metropolitan area, or
ii. 5 kilometres of their length in any other service.
The proposal includes the upgrade of approximately 3.4 kilometres of a main road in
a metropolitan area and therefore is a scheduled activity and would require an EPL.
The POEO Act also identifies a number of pollution offences, including offences
relating to:
The wilful or negligent disposal of waste in a manner that harms or is likely to
harm the environment
The wilful or negligent causing of a substance to leak, spill or otherwise escape
(whether or not from a container) in a manner that harms or is likely to harm the
environment
The wilful or negligent causing of any controlled substance to be emitted into the
atmosphere in contravention of the regulations under the Ozone Protection Act
1989 and in a manner that harms or is likely to harm the environment
Water pollution
Air pollution
Noise pollution
Land pollution and waste.
The construction contractor and Roads and Maritime are required to notify the NSW
Environment Protection Authority (EPA) immediately if a pollution incident occurs that
causes or threatens material harm to the environment.
Threatened Species Conservation Act 1995
The TSC Act aims to conserve biological diversity by protecting and encouraging the
conservation of threatened species, populations and ecological communities and
their critical habitats.
An assessment of the potential impacts of the proposal on threatened species,
populations, ecological communities and critical habitat listed on the TSC Act has
been undertaken in accordance with section 5A of the EP&A Act. This identified that
there would likely be a significant impact on the following:
Duffy’s Forest Ecological Community
Grevillea caleyi (Caley’s Grevillea)
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 76
Review of Environmental Factors
Microtis angusii (Angus’s Onion Orchid)
Pseudophryne australis (Red-crowned Toadlet)
Cercartetus nanus (Eastern Pygmy-possum)
Varanus rosenbergi (Rosenberg’s Goanna)
and would therefore require preparation of a Species Impact Statement (SIS).
Roads and Maritime submitted an application to OEH on 16 April 2015 with regard to
the requirements for the SIS. These were subsequently issued by OEH on 25 May
2015 with amended requirements issued on 21 July 2015. The SIS was prepared by
SMEC Australia. The SIS is being displayed concurrently with this REF, and can be
found on the Roads and Maritime website.
Water Management Act 2000
The Water Management Act 2000 (WM Act) provides for the sustainable and
integrated management of the water sources of NSW for the benefit of both present
and future generations. The WM Act regulates the extraction of and use of water, the
construction of works such as dams and weirs, and the carrying out of activities in or
near water sources in NSW. ‘Water sources' are defined broadly and include the
whole or any part of a river, lake, estuary, place where water occurs naturally on or
below the surface of the ground, and NSW coastal waters.
DPI Water (the former NSW Office of Water) would need to be consulted regarding
any proposed groundwater interception.
Noxious Weeds Act 1993
The Noxious Weeds Act 1993 provides for a coordinated approach to the removal
and control of scheduled noxious weeds across the NSW. No permits or approvals
are required under this Act, but it is the responsibility of Roads and Maritime to
provide for the removal and proper disposal of any listed weeds found within the
proposal site. Noxious weeds are discussed and management measures proposed in
Section 6.1.
National Parks and Wildlife Act 1974
The NPW Act provides that land may be reserved as a national park, nature reserve,
historic site, state conservation area, regional park, Aboriginal area or karst
conservation reserve.
From time to time, circumstances may arise which require the revocation,
recategorisation or adjustment of boundaries of lands reserved under the NPW Act.
Section 47L(1)(b) of the NPW Act provides that only the Government (via a Cabinet
proposal) and ultimately the NSW Parliament (via an Act of Parliament) can decide if
land reserved under the NPW Act may be revoked. The revocation of lands reserved
under the NPW Act will generally only be undertaken as an avenue of last resort and
where no other practical options are available.
Development proposals that require revocation are noted in the NPWS Revocation
Recategorisation and Road Adjustment Policy (NPWS, August 2012). This policy
identifies major Government infrastructure, an example being this proposal, as an
example of potential revocation requirements for a non-permissible activity.
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 77
Review of Environmental Factors
Where a new non-permissible activity or development is proposed by another party
and requires the use of NPWS land, either the park boundary can be re-defined to
exclude the proposed development or the development cannot proceed because it
would encroach upon the park. For example, major Government infrastructure such
as a new highway or major upgrade of an existing road, where no suitable alternative
sites are available outside of NPWS land.
As noted in Section 4.1.1, part of the proposal is located on land within Ku-ring-Gai
Chase National Park and Garigal National Park. Roads and Maritime has acquired
the subject areas of land following the revocation process under the NPW Act.
The NPW Act is also the principal legislation dealing with Aboriginal cultural heritage
in New South Wales. Items of Aboriginal heritage (Aboriginal objects) or Aboriginal
places (declared under section 84) are protected and regulated under the NPW Act.
There are offences and penalties relating to the harm to, or desecration of, an
Aboriginal object or declared Aboriginal place. Harm includes to destroy, deface,
damage or move an object or place.
Under section 90(1) of the Act, the Director-General (now the Chief Executive of
OEH) may issue an Aboriginal heritage impact permit for an activity which will harm
an Aboriginal object. The regulation of Aboriginal heritage impact permits is provided
in Part 6 Division 2 of the Act.
An assessment of the potential for the proposal to impact on Aboriginal heritage
objects or places has been undertaken (refer to Section 6.5 and to Appendix D).
While there are a number of recorded Aboriginal sites near the proposed area of
works, these sites would not be directly affected and therefore no permit would be
required.
Heritage Act 1977
The Heritage Act 1977 provides for the protection and conservation of NSW’s
environmental heritage.
Under the Act, an item is defined as a place, building, work, relic, moveable object or
precinct and a relic is defined as any deposit, artefact, object or material evidence
that:
Relates to the settlement of the area that comprises NSW, not being Aboriginal
settlement, and
Is of State or local heritage significance.
Section 139 requires an excavation permit to disturb or excavate any land knowing or
having reasonable cause to suspect that the disturbance or excavation will or is likely
to result in a relic being discovered, exposed, moved, damaged or destroyed. A
permit is also required to disturb or excavate any land on which the person has
discovered or exposed a relic.
Based on the findings of the historic heritage assessment (refer Section 6.6 and
Appendix E), it is not expected that an excavation permit would be required for the
proposal.

Review of Environmental Factors
Commonwealth legislation
Environment Protection and Biodiversity Conservation Act 1999
Under the EPBC Act, a referral is required to the Australian Government for
proposed ‘actions that have the potential to significantly impact on matters of national
environmental significance or the environment of Commonwealth land.
For ecological communities and species listed under NSW legislation and under the
EPBC Act, there is potential for duplication of the assessment process to satisfy the
requirements of NSW and Commonwealth legislation. In response to this, Roads and
Maritime carried out a strategic assessment of its environmental assessment and
decision-making processes for projects that would not be classified as State
significant infrastructure. The final assessment was submitted to the Australian
Government Department of the Environment in June 2015 for its evaluation against
the requirements of the EPBC Act. The strategic assessment was approved by the
Australian Government Minister for the Environment in September 2015.
The approval means that certain roads and traffic management works undertaken by
Roads and Maritime do not require further consideration under the EPBC Act if
undertaken in accordance with the Program Report – Strategic Assessment of
environmental assessment and decision making by NSW Roads and Maritime
Services, May 2015 (the Program).
The Program applies to eight broad groups of activities identified in Appendix C to
the Program Report. One of these groups relates to ‘primary infrastructure work’ and
the proposed upgrade of Mona Vale Road West would fall under the definition of this
activity.
The Program also applies to certain Protected Matters as identified in Appendix D to
the Program Report. Three are relevant to the proposed upgrade of Mona Vale Road
West:
Grevillea caleyi (Caley’s Grevillea)
Microtis angusii (Angus’s Onion Orchid)
Giant Burrowing Frog (Heleioporus australiacus).
Consideration of impacts upon these three species is provided in the separate SIS
prepared for the proposal and in Section 6.1 of the REF. As per the approved
Strategic Assessment under the EPBC Act (Roads and Maritime, 2015), these
documents would satisfy assessment requirements under the EPBC Act.
Confirmation of statutory position
The proponent and determining authority for the proposed Mona Vale Road West
Upgrade – McCarrs Creek Road, Terrey Hills to Powder Works Road, Ingleside is
NSW Roads and Maritime Services. State Environmental Planning Policy
(Infrastructure) 2007 provides that the proposed works may be carried out without the
need for development consent and are therefore subject to assessment under Part 5
of the EP&A Act.
The matters prescribed by clause 228 of the Environmental Planning and
Assessment Regulation 2000 for consideration by assessments under Part 5 are
reviewed at Appendix A.

Stakeholder and community consultation
Consultation strategy
The communication and engagement objectives for the proposal are to:
Enhance transparency and public accountability
Ensure that decision-making is inclusive of diverse community ideas and opinions
Ensure that strategic planning, project development, and service delivery meets
‘the balance of community’ needs and expectations
Generate organisational efficiencies based on collaborative decision-making and
enhancement of public trust
Provide regular and timely information to community and stakeholders on the
upgrade of Mona Vale Road
Provide clear and concise information about when we are seeking feedback from
the community and stakeholders and what they can comment on versus what are
non-changeable aspects of the upgrade of Mona Vale Road
Ensure impacts on community members and stakeholders are evaluated and this
information is then used to drive the strategy for engagement and consultation.
A number of stakeholders were identified as part of the consultation process. These
stakeholders included:
Local community, including property owners, businesses, community groups and
those directly affected by the proposal
Local schools and child care centres
Emergency services and NSW Health
Government agencies including Northern Beaches Council (former Pittwater and
Warringah Councils), the Department of Premier and Cabinet, UrbanGrowth
NSW, Transport for NSW, State Transit and the Office of Environment and
Heritage
Regional community members, including road users, users of local facilities and
services, and residents of the wider Northern Beaches area.
Community involvement
Roads and Maritime commenced community consultation in May 2011 with the
proposal announcement. Since then, it has provided the community with a range of
opportunities to comment on the proposal. These have included the following:
Provision of information and an invitation to comment – September to November

During the public display period a total of 94 submissions were received, with
comments relating to both Mona Vale Road East Upgrade (subject of a separate
project REF) and Mona Vale Road West Upgrade (subject of this REF). Late
responses received after the 14 November 2014 deadline were accepted and are
considered in this REF.

Issue Community comments and issues raised Roads and Maritime response Where addressed
in REF
General There are concerns that the proposed road
widening is not providing a long term solution
Roads and Maritime is working closely with Northern Beaches
Council and the Department of Planning and Environment and
has taken the projected traffic into account in the traffic
modelling for the proposed road upgrades for Mona Vale
Road East and West. The traffic projections also include the
impacts of future residential land releases in the area. The
proposed road widening would not preclude additional lanes
in the future using the widened carriageway
Section 6.4
There was a request for the proposed road
upgrades to be designed to emulate the free
flowing advantages of a freeway
Roads and Maritime has considered requirements for future
widening. A freeway/motorway style road would require a
larger construction footprint than what is currently proposed
for the upgrades to Mona Vale Road East and West and
would not be consistent with Mona Vale Road between Terrey
Hills and Pymble. Most of the proposed road upgrade follows
the current Mona Vale Road alignment along a ridge line
through two national parks. A motorway style road would not
accommodate local access requirements. These factors,
together with the topography of the area, must be taken into
consideration in determining the practical ‘footprint’ of the
project. The road upgrades that have been proposed by
Roads and Maritime would provide road users with a better
travelling experience and would improve safety and traffic
efficiency.

Constructability Some residents are concerned that the proposed
road upgrades have not taken the current state
of the rock cliffs and rock faces into account,
particularly the impacts on the cliffs on the
northern side of Mona Vale Road heading east.
Roads and Maritime has carried out various technical
investigations to inform the design of the proposed road
upgrades, including geotechnical investigations. Geotechnical
investigations contribute to information on rock face stability.
Where necessary, rock faces would be stabilised as part of
construction.
Section 3.2.14
Maintenance Concerned about concentrated stormwater flows
entering the bushland untreated and how Roads
and Maritime will manage water running off the
road
The design has been carried out to mimic the present day
condition with regard to discharge of water post development
of the proposal
Section 6.3.3 and
Appendix D.
Requests were made to ensure that the surface,
maintenance and clearing of debris on the
upgraded road are maintained to create and
retain a safe cycle route.
Roads and Maritime maintenance contractors would be
required to maintain the widened road including the road
shoulders once the upgrade is completed.
This table.
Cost
effectiveness
Requests were made to ensure the proposed
road upgrades catered for future capacity and
additional lanes.
Roads and Maritime has considered capacity requirements for
future upgrades including the increased traffic from future land
releases in the area. Most of the proposed road upgrade
follows the current Mona Vale Road alignment along a ridge
line through two national parks. The road design, which allows
for the additional two lanes of traffic, would ensure that
impacts on these national parks are minimised and that the
project ‘footprint’ is minimised.

to understand their future requirements for public transport
along this road corridor. Roads and Maritime has also
forwarded this request to Transport for NSW.

Some members of the community made
requests to provide additional pedestrian
facilities including:
Provide a pedestrian bridge rather than
fauna underpasses and overpasses
Provide safe pedestrian crossings at key
intersections along Mona Vale Road and
pedestrian bridges
Provide pedestrian overpass and underpass
facilities at intersections.
The traffic modelling, which is based on existing and
proposed pedestrian demand, shows that pedestrian bridges
are not warranted.
New pedestrian facilities proposed as part of the Mona Vale
West upgrades include:
An off-road shared path (for use by pedestrians and
cyclists) running parallel to the Mona Vale Road
alignment along the length of the upgrade to connect
Ingleside with Terrey Hills
A new signalised pedestrian crossing at the intersection of
Mona Vale Road with Kimbriki Road.

Provision of a horse riding corridor and additional trails for
horse riders linking the national parks with other trails are
outside the scope of work for this project.
Consideration was given to providing a trail as part of the
proposal. However, as part of the revised design undertaken
in 2016, the formerly proposed Wirreanda Road works are no
longer required including the horse trails.
Horse riders would be able to safely cross Mona Vale Road
once they have dismounted at a new signalised pedestrian
crossing at traffic lights at the intersection of Mona Vale Road
and Kimbriki Road.
Horse riders would also be able to safely cross a single lane
of traffic at Tumburra Street which connects to the Caleyi
Trail.

Cyclist facilities Provide off-road cycling connections. An off-road shared path along the length of the upgrade work
would be provided.
Section 3.2.12
Some residents are concerned that the proposed
road upgrades for Mona Vale Road East and
West do not connect at Ingleside. This is a
safety concern for cyclists as the wide shoulders
vary in width and they will be forced into
narrower cycle lanes which collect debris and
nails.
Roads and Maritime would explore options for improving the
cycle connections between the two projects in consultation
with Northern Beaches Council.

Aboriginal community involvement
The proposal has been considered against the requirements of the Procedure for
Aboriginal Cultural Heritage Consultation and Investigation (PACHCI) (Roads and
Maritime Services, 2011). This procedure is generally consistent with the Aboriginal
Cultural Heritage Consultation Requirements for Proponents 2010 (Department of
Environment, Climate Change and Water, 2010). An outline of the procedure is
presented in Table 5-2.
Table 5-2 Outline of PACHCI process
Stage Description
Stage 1 Initial Roads and Maritime assessment.
Desktop assessment to determine whether a Roads and Maritime project
is likely to harm Aboriginal cultural heritage, and whether further
assessment or investigation is required.
Stage 2 Desktop assessment and site survey.
Further assessment and a survey with specific Aboriginal stakeholders
and an archaeologist to assess whether a project would impact
Aboriginal cultural heritage.
Stage 3 Formal consultation and preparation of cultural heritage assessment
report.
Aboriginal parties must be involved in the preparation of these reports in
accordance with legislative requirements and the Aboriginal cultural
heritage consultation requirements for proponents 2010 (Department of
Environment, Climate Change and Water, 2010).
Stage 4 Implement project mitigation measures.
Undertake salvage and/or project implementation in accordance with an
AHIP and/or a Part 5.1/Part 4 approval or Part 5 determination obtained
under the Environmental Planning and Assessment Act 1979.
Following stage 1 of the PACHCI process, Roads and Maritime noted the presence
of previously recorded Aboriginal sites near the proposal site and decided that further
assessment was needed. An Aboriginal archaeological survey report (refer
Section 6.5 and Appendix D) was then prepared by Kelleher Nightingale in
accordance with the requirements of the PACHCI and the Code of Practice for
Archaeological Investigation of Aboriginal Objects in New South Wales: Part 6
National Parks and Wildlife Act 1974 (Department of Environment, Climate Change
and Water, 2010).
The Aboriginal archaeological survey report was prepared in consultation with the
Metropolitan Local Aboriginal Land Council (MLALC). Representatives of MLALC
participated in archaeological surveys carried out in May 2011 and subsequently
provided reports that were then considered as part of the assessment process.
Changes to the concept design resulted in the proposed works exceeding the
Mona Vale Road West Upgrade, McCarrs Creek Road to Powder Works Road 91
Review of Environmental Factors
previous survey area. An additional archaeological survey was undertaken with a
representative of the MLALC in May 2015 to assess these additional areas.
Following consideration of the Aboriginal archaeological survey report, Roads and
Maritime decided that impacts to Aboriginal sites would be unlikely provided suitable
safeguards are implemented.
ISEPP consultation
Part 2, Division 1, Clauses 13-15 of the ISEPP specify consultation requirements for
infrastructure development to be carried out under the ISEPP. These largely relate to
the requirement for public authorities other than local councils to consult with the
relevant local council as part of the assessment process. Consultation is required if
the proposal would affect council infrastructure or services, impact on a local heritage
item or if development would impact on flood liable lands.
Table 5-3 provides a summary of the consultation requirements for the proposal in

the current proposal.
Ensure there is no downstream impact on
Deep Creek tributaries and Coastal Upland
Swamp areas both during and after
construction.
These matters would be considered in
detail during the detailed design phase of
the project.
It is recommended that a broad landscape
based offset strategy is implemented so as to
group the offset requirements of both Mona
Vale Road Upgrades and the Northern
Beaches Hospital Connectivity Upgrades. It
is recommended that any potential offset
sites be sought within the Warringah LGA as
preference.
Roads and Maritime’s offset strategy
would involve both the Mona Vale Road
upgrade and the Northern Beaches
Hospital road connectivity works.
Warringah Council supports commitments to
best practice in wildlife crossing structures
that are built to the maximum scale possible,
such as a land bridge.
Noted.
The temporary and permanent stormwater
and erosion control basins proposed by
Roads and Maritime should be designed in
accordance with Council’s On Site
stormwater detention technical specification.
Temporary and permanent water quality
basins would be designed in accordance
with the ‘Blue Book’ and Council’s on-site
detention specification.
Ongoing liaisons and correspondence have
been occurring between Roads and Maritime
and Council in regards to both the Council-
planned upgrade of Kimbriki Road and the
internal access road into the waste facility, as
well as Roads and Maritime planned Mona
Vale Road works. Parties have agreed to
minimise the extent of abortive works that
Council may undertake on the planned
upgrade of Kimbriki Road. Agreed outcomes
The intersection of Mona Vale Road and
Kimbriki Road has been further refined to
move the alignment to the north to enable
a more level storage platform for heavy
vehicles to stand.

were listed in Council’s ISEPP response
letter relating to :
Compatibility of Council’s design and
Roads and Maritime design – agreed tie
in point.
Design gradients – maximum grade of
12% (with a possibility of increasing to
14% if compatible to AS/Austroads).
The final design by Council matches
existing levels in Kimbriki Road. By
matching these current levels the vertical
alignment is not compliant to Austroads
standards. It is anticipated that Roads and
Maritime design and works will rectify
these non-conformances.
Heavy vehicle design considerations –
Roads and Maritime need to consider
potential issues with heavy vehicles
starting from rest on grade.

OEH notes that proposed land bridge may
require revocation of some OEH land and
therefore requests full consultation and
involvement in the decision making process.
Revocation process has been completed.
Impacts on threatened species and
endangered ecological communities need to
be fully addressed.
A Species Impact Statement has been
prepared as part of the Mona Vale Road
West project and will be exhibited for
community and stakeholder comment at
the same time as the REF exhibition.
A summary of impacts to threatened
species is provided in Section 6.1 of the
REF.
Reference should be made in the REF to any
local ‘hot spot’ roadkill studies including any
undertaken by Roads and Maritime.
Table 8 in the Species Impact Statement
provides a list of all references consulted
including reports of roadkill studies.
Roads and Maritime should consider
measures to avoid clearing of hollow bearing
trees and other important habitat.
Refer to biodiversity safeguards and
mitigation measures provided in
Section 6.1.4
Assessment should consider all options to
avoid and mitigate any impacts on these
areas. Although the impacts of individual
works may be considered low, consideration
should be given to cumulative impacts for
each segment of work, as when taken
together, these may be significant.
An options assessment was undertaken
during project development, taking into
consideration the potential impact of
environmentally sensitive areas (refer to
Section 2.4).
Development of the concept design has

sensitive areas and has first sought to
avoid impact. Where certain impacts were
deemed unavoidable, consideration was
given to reduce impact, manage or offset
impact in that order.
Refer to biodiversity safeguards and
mitigation measures provided in
Section 6.1.4
Should certain impacts be unavoidable, OEH
recommends that Roads and Maritime
develop an offset strategy to address the
direct and indirect impacts of the proposed
works. OEH recommends the use of the
Biobanking Assessment Method to calculate
the required offsets and address the OEH
Principles for Biodiversity Offsets in NSW.
Refer to biodiversity safeguards and
mitigation measures provided in

Government agency and stakeholder involvement
Meetings and briefings were held with key government agencies and stakeholders.
These meetings were designed to ensure agency and stakeholder issues and
concerns were understood, and considered through the preparation of the concept
design and environmental assessment, and that attendees had an opportunity to
discuss any aspect of the proposal. Additionally phone calls, emails and various
correspondence has been ongoing for the project.
