1.0 INTRODUCTION

1.1 PROJECT BACKGROUND

Ford Civil Contracting has been engaged to undertake remediation works at the Newcastle former coke and gas works site at 1 Chatham Rd, Hamilton North. The 74,000m2 site is bounded between Clyde St / Chatham Rd / Styx Creek and the ARTC operated northern freight line railway corridor.

The remediation works addresses the nature of the contamination and the risk of harm identified by the

Management Order (MO) by a ‘cap and contain’ strategy. This allows the contamination issues as

identified in the MO to be remediated in a manner that does not require ongoing active remediation

measures. The proposed remediation encompasses the following approach:

• Site establishment;

• Grubbing of site vegetation;

• Emplacement of pre-existing stockpiles at the site;

• Demolition of existing building & hardstands;

• Site regrading;

• Installation of subterranean barrier wall to redirect groundwater flow;

• Install a low permeability capping layer across the site; and

• Placement of 2 coat spray seal

1.2 REPORT OVERVIEW / PURPOSE Ford Civil Contracting has commissioned Workplace Traffic to prepare a Construction Traffic and Pedestrian Management Plan (CTPMP) to assess and provide management controls to mitigate the impacts of the construction works on the surrounding road network. The plan will detail the proposed construction traffic and pedestrian management measures to ensure road safety and network efficiency during construction. The site-specific overall principles of traffic management during the construction activity include the following measures:

• maintain appropriate public transport access;

• manage and control construction vehicle activity in the vicinity of the site;

• restrict construction vehicle movements to designated routes to and from the site;

• provide an appropriate and convenient environment for pedestrians;

• minimise the impact on pedestrian movements; and

• maintain appropriate capacity for pedestrians at all times on footpaths adjacent to the site along Chatham Rd.

2.0 EXISTING SITE CONDITIONS

The subject site is located in Hamilton North and is bordered by Clyde Street to the northwest, the

railway line to the northeast, Styx Creek to the south and Chatham Road to the west.

The site is currently a vacant block with three single storey buildings situated on the western end of the

site, two of which are heritage lister (those buildings being the one identified central and to the northern

end of the site on Clyde Street).

The existing southern entrance on Chatham Road is currently the primary access point to the site.

The location of the site and its surrounds are shown in Figure 2.1.

2.1 EXISTING ROAD NETWORK

As previously mentioned, the site is directly surrounded by Clyde Street to the northwest, the railway

line to the northeast, Styx Creek to the South and Chatham Road to the West.

Clyde Street runs in a northeast / southwest direction and is defined as a 2 lane 2-way undivided road.

Clyde Street is restricted to a speed limit of 50km/h. The carriageway is approx. 12 metres wide and

houses a railway level crossing. Under a functional road hierarchy, Clyde Street would be considered

a collector road. The section of Clyde Street that joins the site is not currently on any public transport

routes. Traffic volumes were measured on Friday 27 July 2018 and it was found to be low at approx.

7,600 vehicles per day.

Chatham Road runs in a North / South direction and is defined as a 2 lane 2-way undivided road.

Chatham Road is restricted to a speed limit of 50km/h. The carriageway is approx. 11.5 metres wide.

Chatham Road is located on the service route 12 by Newcastle Transport however there are no bus

stops that are directly affected by the site. Traffic volumes were measured on Friday 27 July 2018 and

it was found to be low at approx. 3,270 vehicles per day.

Although Chatham Road is primarily a residential street, it is perceived to be used primarily as a ‘rat-

race’ from Donald Street through to the Pacific Highway at Maryville and vice-versa.

2.2 PEDESTRIAN INFRASTRUCTURE

The current infrastructure for pedestrians is perceived as adequate. Currently the footpaths are

approximately 2.5 metres wide. On Chatham Road there are only footpaths constructed on the

western side of the road (opposite side of road to subject site). Due to the low pedestrian activity, this

setup is supported by Workplace Traffic. The approximate measured traffic volumes for Chatham

Road was measured to be extremely low pedestrian movement, approx. 140 per day. On Clyde

Street, there is a footpath located on both sides of the road however the eastern path crosses over

Clyde Street and doesn’t continue onto Chatham Road. There are existing wear marks in the grass

where pedestrians have been using the grass strip as a pedestrian thoroughfare. Again, with the low

level of pedestrians there is no perceived concern for pedestrians at this location, therefore the grass

verge along Chatham Rd will remain accessible to pedestrians.

3.0 OVERVIEW OF CONSTRUCTION ACTIVITIES

3.1 DESCRIPTION OF CONSTRUCTION ACTIVIES

As addressed in Section 1.1, the proposed remediation encompasses the following general scope of

works:

• Site establishment;

• Grubbing of site vegetation;

• Emplacement of pre-existing stockpiles at the site;

• Demolition of existing building & hardstands;

• Site regrading;

• Installation of subterranean barrier wall to redirect groundwater flow;

• Install a low permeability capping layer across the site; and

• Place 2 coat spray seal. The above works will occur sequentially as the abovementioned, in 3 key similar sized stages. Works will start in the northern portion of the sites and progress south.

A site establishment plan has been prepared and has been included as Appendix A.

3.2 HOURS OF CONSTRUCTION

The current hours of operation which are likely to be approved in the conditions of consent are based on the following:

• Monday – Friday 7:00am to 6:00pm

• Saturday 8:00am to 1:00pm

• No work on Sundays or public holidays The project is programmed for approximately seven months duration with a commencement anticipated for June 2019.

3.3 ON STREET WORKS ZONE Council approval will be obtained for any changes to existing on-street parking signs. Should additional work zones be required, standard council applications will be undertaken.

3.4 CONSTRUCTION TRAFFIC VOLUMES The anticipated traffic volumes to be generated during each phase of the project is summarised in Table 3.1. Peak construction vehicles movements to and from site will be during mobilisation and demobilisation floats, and mobilisation of equipment required for the construction of the subterranean barrier wall.

Page 10: CONSTRUCTION TRAFFIC AND PEDESTRIAN MANAGEMENT …

Workplace Traffic Pty Ltd Created: 16/05/2019 Version: 1.8

CHATHAM RD - CTPMP Modified: 3/06/2019

Page 10 of 36

General vehicle movements are expected to remain consistent through the works with the exception of the capping layer construction where vehicle movements will fluctuate due to the increase in material sourcing. Truck and trailer movements have been capped at 50 per day and hence will peak at 300 movements a week for an anticipated duration of three months during remediation works. Capping construction vehicles will be limited to truck and trailer loads. Vehicles will use the Chatham Road site entrance to access the load / unload zone and the northern gate will be used upon exit of the site. Given the low number of movements and the hours of operation, it is anticipated that the majority of

these movements will be carried out in non-peak periods. Refer to Traffic Guidance Scheme – Appendix

B.

3.4.1 SITE ACCESS

Due to Newcastle City Council’s rejection of the proposed exit routes captured in the EIS, a second

driveway will be constructed to absorb and mitigate impact of the large number of heavy vehicle

movements through the industrial area. Site access will be restricted to two entrance / exit points located

on Chatham Road – Gate 1 (southern existing entrance) and Clyde Street – Gate 2 (opposite 38 Clyde

Street, Hamilton North driveway) refer to Appendix 8.2.

The southern Chatham Road access point will be used primarily for light vehicles and the site entrance

for material importation as specified in Section 3.6 and Section 8.4 to Section 8.6. Protection to the

existing underground infrastructure will be provided around the southern access. Jemena’s asset will

be protected via an engineer certified temporary works design. Temporary works will consist of

installation of a steel plate over the asset. Details of thickness and size is currently still being developed

by the design consultant.

The northern access point will be primarily used as an entrance and exit for large plant / equipment float

mobilisation and demobilisation. For the duration of the works, the northern driveway will be used as an

exit point for heavy vehicles such as those used for the capping material importation as specified in

Section 3.6 and Section 8.4 to Section 8.6. Driveway construction will be constructed in accordance

with Newcastle City Council’s industrial driveway specifications, refer to Appendix 8.3. Upon completion

of the project, the temporary vehicular crossing on Clyde Street will be removed and restored to match

the existing infrastructure.

3.5 CONTRUCTION WORKER PARKING

Chatham Road, Hamilton North is serviced with a bus route (235) across the road from the entrance to

the site. Hamilton train station is also a 15 min walk. There will be an allocated parking area at the

southern end of the site within the nominated site compound area for onsite construction vehicles.

Traffic associated with the development will not utilise public and residential streets or public parking

facilities.

There are currently no parking restrictions on Chatham Road. The hardstand adjacent to the Newcastle

Gas & Coke Office will not be used as an allocated parking area due to its proximity to the heritage

listed building and fencing.

With all of these services available, the construction workers should not cause a disruption to the local

network.

3.6 CONTRUCTION VEHICLE ROUTES

Construction vehicle movements will be restricted to designated routes and confined to the main road network as indicated below. These designated routes will be distributed to all truck drivers in the form of a site induction and posted in the site amenities. Each designated route has been identified with the aim of minimising the impact of construction traffic on the surrounding road network. Construction traffic will not be permitted to queue or park within the residential streets of the surrounding area. As mentioned in section 3.3, there is a daily maximum limit on the number of truck and dog movements for this project. The limit will be capped at 50 movements per day counting one truck movement as in and out of the site.

The site will have 2 gates – the main existing southern entrance for general traffic movements, the secondary located on Clyde Street, refer to Appendix A. New signage will be erected at the 2 gates, refer to TCP 175 and TCP 190, as per Australian Standards 1742 Section 3. Initially, all plant required will be floated from the Ford Civil Contracting holding yard located at 26 Lyn Parade, Prestons, the local staging site at Cabbage Tree Road, Williamtown or from local plant hire suppliers. Due to the size of these floats (anticipated in the order of 24 to 110 tonne excavator, 30 to 40 tonne dump trucks, etc), these vehicles will be required to enter the gate from the northern gate located on Clyde Street, refer to Figure 3.1. The heavy vehicle route for these vehicles will be M1 Motorway, Newcastle Link Rd, Broadmeadow Rd, Clyde Street. Refer to Traffic Guidance Scheme – Appendix B. Location of the additional driveway is governed by surrounding heritage infrastructure, council consultation and the existing road network. The location indicated in Figure 3.1 is assessed as the safest placement along Clyde Street without posing significant safety concerns to the existing network. No modifications will be made to existing on-street parking signs.

All oversize/overmass heavy vehicle movements to transport materials/equipment to/from site must

operate under City of Newcastle (CN) OSOM permit approval. Transport operators must submit

OSOM permit applications minimum two weeks in advance of the proposed travel date/s for our

review and approval. OSOM movements into/out of site on Clyde Street to occur under traffic control

to ensure road safety is not compromised. All traffic control must be conducted under CN’s Road

Occupancy Permit (ROP) approval.

Figure 3.1 North Gate Location

Approx. 60,000 tonnes of clay and 30,000 tonnes of roadbase material will need to be imported to the

site. These materials will be imported from the following nominated source sites:

• Hunter Land (Daracon operated site) site in Rutherford, located at 35 Spitfire Place, Rutherford – Nominated source site for the supply of low permeability clay for the construction of the barrier wall and detention basin – anticipated volume of 4,000 tonnes equivalent to 125 truck and dog loads;

• Woodbury Civil, located at Lot 686 Black Hill Rd, Black Hill – Nominated source site for the supply of low permeability clay for the construction of the capping layer system – anticipated volume of 56,000 tonnes equivalent to 1,750 truck and dog loads; and

• Boral Recycling, located at 27 Egret St, Kooragang – Nominated source site for the supply of recycled concrete roadbase material for the construction of the trafficable pavement layer – anticipated volume of 30,000 tonnes equivalent to 938 truck and dog loads.

All vehicle number plates importing material to site or delivering materials from suppliers will be verified the previous day or the morning of to mitigate rogue vehicles entering and exiting site. The prescribed approach and return route for the nominated material import source sites are as follows: Hunter Land (Daracon operated site), Rutherford – 35 Spitfire Place, Rutherford (Figure 3.2) See Appendix 8.4 for detail.

4.0 CONSTRUCTION TRAFFIC MANAGEMENT

4.1 TRAFFIC GUIDANCE SCHEME

The proposed Traffic Guidance Scheme (TGS) for the construction works are included in Appendix B. The plan presents the principles of traffic management and are subject to Safework NSW requirements and modification to suit on-site conditions if required. Detailed information for work site operations is contained in the RMS Traffic Control at Work Sites manual. The control of traffic at work sites must be undertaken with reference to Safework NSW requirements and the contractors own Workplace Health and Safety Manuals. The proposed TGS for the construction works include the following considerations:

• Construction vehicle activity.

• Length of time for the proposed works

• The movement of trucks to/ from the Works site will be under normal traffic conditions and managed by qualified RMS traffic controllers.

• Speed and volume of regular motorists in and around the road network.

• Pedestrians and all passing vehicles will maintain priority at all times.

4.2 EMERGENCY RESPONSE PLAN

There are two site muster points identified, as per the project emergency response plan.

Emergency vehicles will access the site in the case of emergency via one of the two nominated site

gates on Chatham Road or Clyde Street, by election of the closest gate to the incident occurred. The

gate will be communicated to emergency response units.

Refer to the project emergency response plan for further detail.

4.3 PEDESTRIAN MANAGEMENT

During the construction period, pedestrian movements adjacent to the site will be maintained. Chainwire fencing is existing along the edges of the site to keep pedestrians safe from the activities on site. Should any unforeseen activities require the temporary closure of the Clyde Street footpath during any stage of the works, a Traffic Guidance Scheme (TGS) will be developed and implemented by the contractor to ensure pedestrian safety, refer to 8.3.

5.0 WORKPLACE AND TRAFFIC SAFETY TRAINING

5.1 GENERAL

All construction workers and visitors to the site will be made aware of construction traffic hazards

during the site-specific inductions.

5.2 INDUCTION SAFETY TRAINING

Site inductions, including site layout and emergency procedures, will be carried out as soon as new

workers and visitors arrive on site. Due to many differing site constraints, the induction process will

cover site specific issues such as internal access roads, third party assets and mandated materials

supplier routes.

Truck driver inductions will be provided for all vehicles upon entrance to the site.

These inductions will include the following;

• current site access routes

• designated quarry routes

5.3 ACCREDITED WORKZONE TRAFFIC CONTROLLERS AND MANAGEMENT

TRAINING

Only trained and accredited traffic control personnel will be used for all traffic control operations. All

traffic controllers will be assessed for competency prior to starting on-site by a licenced RMS

Trainer/Assessor. The minimum requirement for Traffic Control is hold the RMS ‘Traffic Controller’

licence.

6.0 INSPECTIONS AND MONITORING

6.1 INSPECTIONS

Inspections will be carried out in accordance with the RMS Traffic Control at Worksites Manual (2010)

and the AS1742.3 (MUTCD) to ensure the safe movement of traffic and the protection of persons and

property in and around the worksite. Traffic control audits are recorded on the appropriate documents

as part of normal traffic control procedures.

The environmental officer will verify truck routes being undertaken by truck drivers from the material

source sites. This will be done by electing a random truck to be followed for every 1 per 5,000 tonne

imported material. A report will be generated and filed for quality control.

6.2 MONITORING

• Visual monitoring of all traffic movements on site will be carried out to ensure the safe movement of traffic and the protection of persons and property through and around the site;

• The surrounding road network will be monitored to ensure road conditions continue to support safe working and driving;

• Following periods of heavy rain or adverse weather conditions, all roads will be inspected prior to heavy vehicle traffic use to ensure driver and vehicle safety;

• The site will be regularly inspected to ensure all signs and devices are in place, still clearly visible and performing their function in directing traffic and alerting drivers of safety issues.

7.0 OTHER CONSIDERATIONS

7.1 COMMUNITY NOTIFICATION

All community notifications (including local schools, surrounding businesses and residents) to be

managed through Jemena’s nominated community liaison manager.

7.2 HERITAGE AND CULTURAL

There are 2 heritage listed buildings on site. These respective areas will be delineated with physical

protection barrier such as jersey kerbs or water filled barriers or similar.

GHD | Report for Jemena Gas Networks (NSW) Ltd – Former Newcastle Gasworks (Clyde Street) Remediation Project, 2217312 | 1

1. Introduction

1.1 Overview

Jemena Gas Networks (NSW) Ltd (Jemena) is proposing to remediate the Former Newcastle

Gasworks at 1 Chatham Road, Hamilton North (the Project). The Project is located on Lot 1 DP

79057 and Lot 270 DP 812689 within the Newcastle Local Government Area (LGA) in the

Lower Hunter region of New South Wales (NSW) (the Project area) (Figure 1-1).

The Project is proposed to reduce the risk to human health and the environment in accordance

with management order number 20151403 (Management Order) issued by the NSW

Environment Protection Authority (EPA) on 21 December 2015 under section 14 of the

Contaminated Land Management Act 1997 (NSW). The Jemena Gas Networks (NSW) Limited

Stage 2 Remedial Action Plan Former Newcastle Gasworks 1 Chatham Road, Hamilton North,

NSW (JBS&G, 2017) (RAP) has been prepared to address the requirements of the

Management Order.

GHD Pty Ltd (GHD) has been engaged by Jemena to prepare an Environmental Impact

Statement (EIS) to support a development application for the Project as State significant

development under Part 4, Division 4.7 of the Environmental Planning and Assessment Act

1979 (NSW) (EP&A Act).

This Traffic Impact Assessment (TIA) has been prepared as part of the EIS in accordance with

the provisions of the EP&A Act and addresses the Department of Planning & Environment

(DP&E) Secretary’s Environmental Assessment Requirements (SEARs) (SSD 7676) issued for

the Project on 8 September 2016.

1.2 Background

Jemena owns the Project area located at 1 Chatham Road, Hamilton North a suburb within

Newcastle (see Figure 1-1).

The Project area was operated by the Newcastle Gas Company from 1913 to 1985, producing

‘town gas’ as well as by-products that included ammonia liquors, coal tars and spent oxides.

Over time, these by-products accumulated in the soil. Other solid materials, including concrete,

asphalt and building materials are scattered throughout the Project area. The Project area is

heavily contaminated and currently presents human health and environmental risks arising from

the presence of contamination in soils (including stockpiles), tar sources and hydrocarbon,

cyanide, and ammonia contaminated groundwater migrating off-site.

The Project area was declared significantly contaminated land by the EPA on 18 August 2011

under the CLM Act (Declaration No 20111101/Area No. 3060).

In response, Jemena has embarked on a staged remediation approach which initially comprised

preliminary remediation works of above ground infrastructure (Stage 1 works) to prepare the

Project area for the proposed development that is the subject of this EIS, being the main

remediation works specified in this EIS (Stage 2 – the Project). The Stage 1 work was

completed in 2015 and documented in Clyde Street (former Newcastle Gasworks) Remediation

Project – Validation Report (Parsons Brinckerhoff (PB), 2015). A number of stockpiles are

currently present on site, as a result of the Stage 1 remediation works. These stockpiles include

building rubble and potentially impacted soils and are covered by anchored geofabric to prevent

erosion of contaminated materials. These stockpiles are regularly inspected to check that the

geofabric is in place and working effectively until such time as Stage 2 remediation occurs,

following the grant of development consent.

GHD | Report for Jemena Gas Networks (NSW) Ltd – Former Newcastle Gasworks (Clyde Street) Remediation Project, 2217312 | 3

Following completion of Stage 1 works, on 29 October 2015, the Project was declared as State

Significant Development (SSD) by the NSW Minister for Planning, under section 4.36(3) of the

EP&A Act. On 21 December 2015 the EPA issued Management Order (no. 20151403) to

Jemena in accordance with the CLM Act. The Project, for which the EIS applies, is to address

the requirements of the Management Order.

In accordance with one of the requirements of the Management Order, the RAP was prepared

for the Project. The RAP outlines the remediation strategy for the Project.

1.3 Objectives of the Project

The objectives of the Project are to:

Achieve compliance with the requirements of the Management Order by:

– Addressing groundwater within the Project area that has been degraded by gasworks

waste contaminants at concentrations exceeding criteria for beneficial use and

protection of aquatic ecosystems.

– Addressing contaminated groundwater within the Project area which may migrate

further off-site and ultimately impact the Hunter River.

– Addressing risks posed by vapours during subsurface works within the Project area.

Develop and implement measures to manage and mitigate the potential environmental,

heritage, social, and health and safety impacts from the Project that are identified in the

EIS.

Develop and implement a long-term environmental management plan (LTEMP) to

address residual contamination within the Project area following the Stage 2 remediation

works (being the remediation works comprising the Project).

It is envisaged that redevelopment of the Project area may occur at a later stage. Whilst an

objective of the Project is to reduce the risk to human health and the environment in accordance

with the Management Order, any remediation works required to make the Project area suitable

for a specific future use would be the subject of a separate assessment and approvals process.

1.3.1 Key features of the Project

The Project proposes to remediate the Project area to address and manage the risk to human

health and the environment in accordance with the requirements of the Management Order and

the RAP, and would be undertaken as outlined below.

Early works

Early works would be undertaken in advance of the main project works over an approximate

one week period and would involve:

Installation of nested monitoring wells immediately upgradient and downgradient of the

subterranean barrier wall at four locations, with each nested well comprising two wells

(total of 16 wells).

Installation of automated pressure transducers/loggers programmed to log water pressure

data at not less than hourly intervals, including in wells along the subterranean barrier

wall alignment, and in selected off-site wells on Emerald Street (parallel to Chatham

Road).

Site establishment

Site establishment would be undertaken over an approximate two week period and would

involve:

Establishment of environmental and safety controls.

Establishment of site compound/parking areas.

Clearing and mulching of vegetation and stockpiling on-site prior to being transported off-

site as general solid waste (non-putrescible) for recycling/disposal at an appropriately

licensed facility.

Reinforcement of the driveway to protect an existing gas main located beneath the site

access on the eastern side of Chatham Road.

Remediation

Remediation would be undertaken over an approximate seven month period. Remediation

would occur in a staged manner with work commencing in the north of the Project area and

progressing to the south. Further information on the indicative Project staging is provided in the

EIS. Remediation would involve:

Demolition of the existing concrete slabs and Former Residence Building. Demolition

materials would either remain on-site (following crushing and screening) for use during

the remediation phase, located behind the subterranean barrier wall and below the

capping layer, or transported off-site as special waste (asbestos waste) or general solid

waste (non-putrescible) for disposal at an appropriately licensed facility.

Relocation of stockpiles generated from the previously completed Stage 1 remediation

works behind the subterranean barrier wall and below the capping layer, with screening

and crushing of building rubble undertaken prior to placement.

Installation of an approximately 510 metre long subterranean barrier wall to redirect

groundwater flow around the areas of highest contamination (primarily where old/stable

non aqueous phase liquid (NAPL) has been identified).

Capping layer construction and regrading of the entire Project area, including installation

of drainage and sealing of the capping layer via a bitumen spray seal. In the final stage of

work the site compound/parking area in the south-west corner would be removed.

Demobilisation

Demobilisation would be undertaken over an approximate one week period and would involve:

Removal of redundant environmental and safety controls.

General site tidy up activities.

Post-remediation

Jemena would undertake long-term management and monitoring of the Project area in

accordance with EPA requirements.

A detailed description of the Project is provided in Section 4 of the EIS, with a Project overview

shown on Figure 1-2. Three hotspot areas were identified in the RAP as requiring excavation.

However, based on additional soil sampling and analysis undertaken by GHD (2018), there was

no evidence of subsurface contamination in these areas requiring removal. As such, the

previously nominated hotspot areas are not included as part of the scope of the Project, with

this approach endorsed by the Site Auditor and the EPA.

1.4 Scope of this assessment

This report investigated the likely impact of the additional traffic generated by the Project. The

report aimed to address the Secretary’s Environmental Assessment Requirements including:

Accurate predictions of the traffic generated by the remediation works and the impact

on the safety and capacity of the surrounding road network and key intersections

To address these requirements, the following scope of works has been undertaken:

Review available information and identify the existing conditions on the surrounding

transport network.

Obtain and assess crash statistics and identify road safety implications.

Assess the likely change in traffic due to the Project.

Assess the traffic implications on road network capacity, safety and amenity from the

proposed increase in traffic to determine whether roads affected by the Project are

capable of accommodating the additional traffic demand.

1.5 Information and data sources

The following information and data sources have been used in preparing this report:

2. Existing conditions

2.1 Transport network

For the purpose of this report, the transport network consists of Chatham Road, Clyde Street,

Boreas Road, Broadmeadow Road and Donald Street/Griffiths Road.

2.1.1 Chatham Road

Chatham Road connects Donald Street/Griffiths Road to Clyde Street. Chatham Road is a two

lane, two-way road, approximately nine metres (m) wide, with parking permitted on both sides of

the road. The speed limit on Chatham Road is 50 kilometres per hour (km/h). Land use on the

western side of Chatham Road opposite the Project area is residential.

Recent traffic volumes on Chatham Road, north of Boreas Road, were obtained from the City of

Newcastle for the period 15 – 23 August 2017 and are summarised in Table 2-1 and Table 2-2.

Average daily volumes on Chatham Road are in the order of 3,500 vehicles. The percentage of

heavy vehicles on Chatham Road is 1.3 percent of the total vehicles.

Speed data for Chatham Road was obtained for the same period. The speed data shows a

relatively low compliance with the posted speed limit, with an average speed of 54 km/h and an

85th percentile speed of 62 km/h.

Level of service can be used as a performance measure for traffic efficiency. The RTA (2002)

Guide to Traffic Generating Developments provides one-direction traffic flow limits for different

levels of service as shown in Table 2-3.

One-way peak hour volumes on Chatham Road are in the order of 175 vehicles (southbound) in

the AM peak and 163 vehicles (in each direction) in the PM peak (Table 2-2). Chatham Road is

therefore currently operating at level of service A.

Table 2-3 Urban road peak hour level of service criteria

Level of Service

Description One lane (veh/h)

Two lanes (veh/h)

A This, the top level, is a condition of free flow in which individual drivers are virtually unaffected by the presence of others in the traffic stream. Freedom to select desired speeds and to manoeuvre within the traffic stream is extremely high, and the general level of comfort and convenience provided is excellent.

200 900

B This level is in the zone of stable flow and drivers still have reasonable freedom to select their desired speed and to manoeuvre within the traffic stream, although the general level of comfort and convenience is little less than that of the level of Service A.

380 1400

C This service level is also in the zone of stable flow, but most drivers are restricted to some extent in their freedom to select their desired speed and to manoeuvre within the traffic stream. The general level of comfort and convenience declines noticeably at this level.

600 1800

D This level is close to the limit of stable flow but is approaching unstable flow. All drivers are severely restricted in their freedom to select their desired speed and to manoeuvre within the traffic stream. The general level of comfort and convenience is poor, and small increases in traffic flow will generally cause operational problems.

900 2200

E This occurs when traffic volumes are at or close to capacity and there is virtually no freedom to select desired speeds or to manoeuvre within the traffic stream. Flow is unstable and minor disturbances within the traffic stream will cause a traffic-jam.

1400 2800

2.1.2 Clyde Street

Near the Project area, Clyde Street is a two lane, two-way road, approximately 12 m wide.

Parking is permitted on both sides of the road. Surrounding land use is industrial in the vicinity

of the Project area, with residential land south of Clyde Street to the west of the Project area.

There is a rail level crossing on Clyde Street at the north-east corner of the Project area. The

speed limit on Clyde Street is 50 km/h.

Recent traffic volumes on Clyde Street, north of Chatham Road, were obtained from the City of

Newcastle for the period 15 – 23 August 2017 and are summarised in Table 2-4 and Table 2-5.

Average daily volumes on Clyde Street are in the order of 7,500 vehicles. The percentage of

heavy vehicles on Clyde Street is 1.4 per cent of the total vehicles.

Speed data for Clyde Street was obtained for the same period. The average speed was

41.7 km/h and the 85th percentile speed was 48 km/h.

One-way peak hour volumes on Clyde Street are in the order of 394 vehicles (northbound) in

the AM peak and 435 vehicles (southbound) in the PM peak. Using the criteria summarised in

Table 2-3, Clyde Street is currently operating at level of service C.

2.1.3 Boreas Road

Boreas Road is a residential collector street connecting Chatham Road and Broadmeadow

Road. Boreas Road is a two lane, two-way road, approximately 12 m wide. Parking is permitted

on both sides of the road. The western end of Boreas Road provides access to the Hamilton

North Bowling Club and Smith Park. The speed limit on Boreas Road is 50 km/h.

Traffic volume data is not available for Boreas Road.

2.1.4 Broadmeadow Road

Broadmeadow Road connects Donald Street/Griffiths Road to Clyde Street. Broadmeadow

Road is a two lane, two-way road, approximately 12 m wide. Parking is permitted on both sides

of the road and the adjoining land use is mostly commercial and light industrial. The speed limit

on Broadmeadow Road is 50 km/h.

Traffic volume data is not available for Broadmeadow Road.

2.1.5 Donald Street/Griffiths Road

Donald Street/Griffiths Road is an arterial road with two lanes in each direction divided by a

central median. It is part of one of the primary east-west arterials in the Newcastle region,

connecting the Hunter Expressway and M1 Pacific Motorway with the Newcastle central

business district (CBD). The road is known as Griffiths Road west of Chatham Road, and

Donald Street east of Chatham Road. The posted speed limit is 70 km/h.

Traffic volumes on Donald Street, east of Chatham Road have been obtained from the Roads

and Maritime (2016) Traffic Volume Viewer. Donald Street carries in the order of 34,000

vehicles per day near Chatham Road. Peak hour traffic volumes are in the order of 2,700

vehicles per hour in both the AM and PM peak periods.

One-way peak hour volumes on Donald Street are in the order of 1,600 vehicles (eastbound) in

the AM peak and 1,400 vehicles (westbound) in the PM peak. Using the criteria summarised in

Table 2-3, Donald Street is currently operating at level of service C.

The intersection between Donald Street/Griffiths Road and Chatham Road is give-way

controlled. There are channelised right turn lanes on Donald Street/Griffiths Road. There is an

auxiliary left turn lane for entry to the northern approach of Chatham Street.

The intersection between Griffiths Road and Broadmeadow Road is controlled by traffic signals,

with a separate right turn phase for turns out of Broadmeadow Road.

2.2 Pedestrians and cyclists

There is a footpath on the western side of Chatham Road adjacent to the site. There is frequent

interruption to the footpath by driveway crossovers. There are footpaths on both sides of Clyde

Street, Boreas Road and Broadmeadow Road. There is a pedestrian crossing with a kerb

extension on Broadmeadow Road, just south of Boreas Road.

There are no formal facilities for cyclists in the area.

2.3 Public transport

There is a bus route on Chatham Road and Clyde Street (west), which diverts along Boreas

Road and Newcastle Street and does not run adjacent to the Project area. There is also a bus

route on Broadmeadow Road.

2.4 Road safety performance

Crash data in the Newcastle area, for the five-year period between 2012 and 2016, is available

on the Transport for New South Wales, Centre for Road Safety website.

During this period, there were three crashes in the vicinity of the Project area, at the intersection

of Chatham Road and Boreas Road. All three crashes involved a vehicle turning out of Boreas

Road colliding with a vehicle travelling north on Chatham Road. Two of these crashes involved

moderate injury and one was a non-casualty crash.

There were ten crashes at the Donald Street/Griffiths Road/Chatham Road intersection between

2012 and 2016. Half of these crashes were ‘cross traffic’ crashes. There were two ‘right through’

crashes. Three crashes involved injury, while the remainder were non-casualty crashes.

3. The project

3.1 Overview

The Project proposes to remediate the Project area to reduce the risk to human health and the

environment in accordance with the Management Order issued by the EPA and would be

undertaken in accordance with the RAP. The site operated as a gasworks from 1913 to 1985.

The proposed remediation of the site involves capping and hydraulic control.

3.2 Work program

The total work program is expected to be between seven months. Site establishment works,

including development of a compound/parking area, are expected to occur over a two week

period. Remediation works are expected to occur over a seven month period. Demobilisation

works, including decommissioning of the compound/parking area, are expected to occur over a

one week period.

3.3 Work hours and workforce

All work would be undertaken during standard working hours:

Monday to Friday: 7.00 am to 6.00 pm

Saturday: 8.00 am to 1.00 pm

No work on Sundays or Public Holidays

Staff may arrive and leave site before and after these times to ‘start-up’ and ‘shut-down’, but

works would not occur outside the times specified above.

Peak workforce numbers are expected to be up to 10 full-time equivalent (FTE) employees

during site establishment and demobilisation and up to 22 FTE employees during the

remediation phase.

3.4 Site access and parking

Access to the site is currently off Chatham Road, as shown in Figure 3-1. The existing access

would be used for the both light and heavy vehicles for the duration of the Project.

A temporary on-site car park would be established in the south-western corner of the Project

area. All parking for the Project would be within the Project area, with no parking on public

streets. The location of the proposed car park is shown in Figure 3-1.

3.5 Traffic generation

The anticipated traffic to be generated during each phase of the Project is summarised in

Table 3-1.

Light vehicle volumes are expected to be 10 vehicles per day during site establishment and

demobilisation, and 22 vehicles per day during the remediation phase.

Heavy vehicle volumes are expected to be two vehicles per day for the majority of the

remediation period. Heavy vehicle volumes would peak during construction of the capping layer,

with 50 vehicles per day for a three-month period. Heavy vehicles would be a truck and dog

trailer combination.

Long-term management and monitoring of the site post-remediation would generate low traffic

volumes with one heavy vehicle and two light vehicles on average per week.

4. Traffic impacts

4.1 Access route

4.1.1 Heavy vehicles

Jemena has advised that trucks delivering material to the site would originate from, and return

towards, the west via Donald Street/Griffiths Road and Chatham Road as shown in Figure 4-1.

Inbound trucks would turn left off Donald Street/Griffiths Road into Chatham Road, and then

right into the site. The left turn from Donald Street/Griffiths Road is an un-conflicted movement.

The right turn into the site would need to give way to southbound traffic in Chatham Road, but

these volumes are relatively low and gaps would be frequent. As such, the inbound route is

clear and is considered the most appropriate route. However, the outbound route for trucks is

not straightforward.

The intersection between Chatham Road and Donald Street/Griffiths Road is give-way

controlled. Donald Street/Griffiths Road has four lanes and carries high traffic volumes, in the

order of 34,000 vehicles per day. Vehicles turning right out of Chatham Road are required to

select an appropriate gap in both directions of traffic. During the last five years, there have been

five cross-traffic accidents at the intersection.

Due to the difficulty in making right turns out of Chatham Road, and the associated road safety

concern, alternative routes have been investigated for the outbound movement. These options

are summarised in Table 4-1 and illustrated in Figure 4-2.

Table 4-1 Options for outbound heavy vehicle route

Option Pros Cons

Left onto Chatham Road, right onto Donald Street/ Griffiths Road

(refer to green route in Figure 4-2)

Direct route.

Minimal roads affected.

Right turn onto Donald Street/Griffiths Road difficult due to high traffic volumes and four lanes of traffic.

Left onto Chatham Road, left onto Donald Street and turning around using Swan Street, Hudson Street and Samdon Street

(refer to light blue route in Figure 4-2)

Avoids uncontrolled right turn onto Donald Street/Griffiths Road.

Increased travel distance of approximately 1.6 km.

Increased truck volumes on Swan Street, Hudson Street and Samdon Street (zoned mixed use).

Right onto Chatham Road, left onto Boreas Road, left onto Broadmeadow Road, right onto Donald Street/ Griffiths Road

(refer to yellow route in Figure 4-2)

Avoids uncontrolled right turn onto Donald Street/Griffiths Road.

Increased travel distance of approximately 100 m.

Amenity impact from increased truck volumes on residential street.

Potential safety issue with pedestrian crossing on Broadmeadow Road near Boreas Road intersection.

Page 65: CONSTRUCTION TRAFFIC AND PEDESTRIAN MANAGEMENT …

GHD | Report for Jemena Gas Networks (NSW) Ltd – Former Newcastle Gasworks (Clyde Street) Remediation Project, 2217312 | 15

Option Pros Cons

Right onto Chatham Road, left onto Clyde Street, left onto Broadmeadow Road, right onto Donald Street/ Griffiths Road

(refer to dark blue route in Figure 4-2)

Avoids uncontrolled right turn onto Donald Street/Griffiths Road.

Clyde Street is already a through route.

Increased travel distance of approximately 600 m.

Tight turning movement onto Clyde Street. Crossing the centre line likely to be required for truck and dog trailer combination. Traffic control may be required to restrict Chatham Road to one-way northbound. This would cause inconvenience and increased travel distance for local residents.

The preferred alternative is to use either Boreas Road or Clyde Street to access Broadmeadow

Road, allowing a right turn onto Donald Street/Griffiths Road at traffic signals. This avoids the

uncontrolled right turn onto Donald Street/Griffiths Road.

Clyde Street has commercial and light industrial land uses and is a through traffic route. It is

therefore suitable as a heavy vehicle access route. However, the left turn onto Clyde Street from

Chatham Road requires a tight turning movement for heavy vehicles which would likely result in

trucks crossing the centreline of Chatham Road. This may lead to conflicts at the Chatham

Road/Clyde Street intersection. Traffic control could be provided to restrict Chatham Road to

one-way northbound; however, this would cause inconvenience and increased travel times for

residents of Chatham Road.

The use of Boreas Road is considered the least likely to result in an increase in crashes on the

surrounding road network as a result of the Project. This route, is therefore recommended for

outbound heavy vehicle movements. The traffic impacts of the Project on the surrounding road

network are discussed further in the following sections.

4.1.2 Light vehicles

It is expected that the majority of light vehicles would access the site from the south. It has been

assumed that 90 per cent of light vehicle movements to the site would be from the south

(Donald Street/Griffiths Road) and 10 per cent from the north (Clyde Street). However, it is

expected that some light vehicles would also use Boreas Road to avoid the uncontrolled right

turn out of Chatham Road onto Donald Street/Griffiths Road. It has been assumed that 60 per

cent of light vehicles would exit the site to the south and 40 per cent would exit the site to the

north.

4.2 Traffic efficiency

4.2.1 Chatham Road

Chatham Road currently carries in the order of 3,500 vehicles per day. The expected increase

in daily traffic volumes on Chatham Road is summarised in Table 4-2 (south of access) and

Table 4-3 (between access and Boreas Road).

The Project is expected to generate 50 heavy vehicles and 33 light vehicles per day (based on

the assumed directional split of light vehicles in Section 4.1.2) south of the access, during the

peak three-month period. This represents an increase of 2 per cent of total traffic volumes.

Between the existing access and Boreas Road, the Project is expected to generate 50 heavy

vehicles and 11 light vehicles per day during the peak three-month period.

During the remainder of the remediation program, the volume of heavy vehicles would reduce to

two trucks per day on Chatham Road, either side of the access.

Peak hour traffic generation has been estimated based on the expected daily traffic generation

and is summarised in Table 4-4. South of the access, light vehicle volumes on Chatham Road

generated by the Project are expected to be up to 20 vehicles per hour in the morning peak

(staff arriving) and up to 13 vehicles per hour in the evening peak (staff departing). North of the

access, light vehicle volumes are expected to be up to two vehicles per hour in the morning

peak and nine vehicles per hour in the evening peak. This is a conservative estimate. As the

working hours are 7 am to 6 pm on weekdays, it is likely that many of the light vehicle

movements generated would occur outside the peak periods.

Page 69: CONSTRUCTION TRAFFIC AND PEDESTRIAN MANAGEMENT …

GHD | Report for Jemena Gas Networks (NSW) Ltd – Former Newcastle Gasworks (Clyde Street) Remediation Project, 2217312 | 19

Heavy vehicle movements are expected to be spread across the working hours of 7:00 am to

6:00 pm on weekdays and 8:00 am to 1:00 pm on Saturdays. As a conservative estimate, it is

assumed that up to eight heavy vehicle movements in each direction would occur during the

peak hour, during the capping layer construction. At other times during the remediation

program, the peak hour volume is expected to be one to two heavy vehicles in each direction

per hour.

It is considered that the increase in traffic volumes on Chatham Road can be absorbed without

any significant impact on traffic efficiency. As shown in Table 4-4, Chatham Road would still

operate at level of service A under the anticipated traffic volumes.

4.2.2 Boreas Road and Broadmeadow Road

The Project would increase traffic volumes on Boreas Road and Broadmeadow Road from

outbound movements from the Project area. Increased traffic volumes on these roads during the

peak three-month period are expected to be up to 50 heavy vehicles and seven light vehicles

per day. Peak hour volumes on these roads are estimated to be up to eight heavy vehicles and

seven light vehicles per hour. This increase in traffic volumes will be able to be absorbed

without any significant impact on traffic efficiency.

4.3 Amenity

4.3.1 Heavy vehicles

Heavy vehicles on residential roads have an impact on the amenity of the area. Boreas Road is

a local residential street and currently carries relatively low traffic volumes. The Project would

increase heavy vehicle movements on Boreas Road by 50 movements per day during the peak

three-month period.

While the increased truck volumes would have some impact on the amenity of this residential

area, these volumes would be limited to the peak three-month period. For the remainder of the

remediation program, heavy vehicle volumes would be only two per day on Boreas Road.

4.3.2 Total traffic volumes

Chatham Road is used as a through route and currently carries in the order of 3,500 vehicles

per day. The RTA Guide to Traffic Generating Developments (2002) provides guidance on

environmental capacity for local roads. Environmental capacity performance standards are

summarised in Table 4-5. For collector streets with a speed of 50 km/h, the peak hour

environmental goal is 300 vph, with a maximum volume of 500 vph.

Page 70: CONSTRUCTION TRAFFIC AND PEDESTRIAN MANAGEMENT …

Collector Street 50 300 environmental maximum goal

500 maximum

Source: RMS Guide to Traffic Generating Developments

Existing peak hour volumes on Chatham Road (323-327) are slightly higher than the

environmental maximum goal, but well below the maximum peak volume for a collector street. It

is considered that the additional traffic volumes during the peak period, up to 20 light vehicles

and eight heavy vehicles per hour, would be able to be absorbed without any significant impact

on safety or amenity. This equates to up to 355 vehicles per hour, which is still well below the

maximum peak hour volume for a collector street.

4.4 Access impacts

4.4.1 Turn movements

The expected turn movements at the site access are summarised in Table 4-6 (daily) and

Table 4-7 (peak hour).

The existing access is expected to operate effectively under the proposed traffic volumes, given

the relatively low turn movements and the existing traffic volumes on Chatham Road. The

access is not expected to cause significant delays on Chatham Road.

4.4.2 Sight distance

Safe intersection sight distance (SISD) is the minimum sight distance that should be provided

on the major road at any intersection or access. It is the sight distance required for a driver of a

vehicle on the major road to observe a vehicle on the minor approach moving into a collision

situation and to decelerate to a stop before reaching the collision point. Austroads (2017) Guide

to Road Design Part 4A: Unsignalised and Signalised Intersections provides requirements for

SISD.

While the speed limit on Chatham Road is 50 km/h, recent speed data shows an 85th percentile

speed of 62 km/h. The required SISD for an 85th percentile speed of 62 km/h based on

Austroads is 129 m. Chatham Road is straight and flat near the site access point. The required

sight distance is achieved.

Given the low compliance with the posted speed limit, localised traffic management in the

vicinity of the site access (e.g. trucks entering signage) could be considered to slow vehicle

speeds.

4.4.3 Adjacent accesses

There is a community centre on Chatham Road opposite the Project site, with an access onto

Chatham Road just north of the site access. Good sight distance is available at the community

centre access.

Given the traffic volumes generated north of the site access are relatively low, and adequate

sight distance is available at the community centre access, the Project is not expected to impact

the community centre access.

4.5 Parking

The Project involves construction of a compound/car park at the south-western corner of the

Project area as shown in Figure 3-1. All parking for the Project would be on site and therefore

there would be no impact on surrounding streets. Construction of the car park should ensure

there is sufficient space for all employees to park on site.

4.6 Pedestrians and cyclists

The site access on Chatham Road would not affect pedestrians as there is no footpath on this

side of Chatham Road and minimal pedestrian demand on this side of the road given the

absence of any active land uses.

There is a pedestrian zebra crossing on Broadmeadow Road, just south of the Boreas Road

junction. There is signage on the Boreas Road approach, advising drivers to watch for

pedestrians, which assists in alerting drivers of the crossing. Visibility to the crossing is also

good.

It is considered that the additional traffic on Chatham Road, Boreas Road and Broadmeadow

Road can be managed without any significant impact on pedestrians or cyclists.

4.7 Road safety impacts

The crash data shows three crashes in the last five years at the intersection between Chatham

Road and Boreas Road. Each of these crashes involved a vehicle turning out of Boreas Road

colliding with a vehicle travelling north on Chatham Road. A hold line on Boreas Road could be

considered to improve safety at this intersection.

Page 72: CONSTRUCTION TRAFFIC AND PEDESTRIAN MANAGEMENT …

22 | GHD | Report for Jemena Gas Networks (NSW) Ltd – Former Newcastle Gasworks (Clyde Street) Remediation Project, 2217312

The Project is not expected to cause any significant detrimental impact to road safety in the

vicinity of the site based on the following:

The sight distance at the site access on Chatham Road meets the Austroads

requirements for SISD.

The site access on Chatham Road would not impact pedestrians, as the existing footpath

is on the other side of the road.

While the Project would increase left turns onto Broadmeadow Road from Boreas Road,

signage assists in alerting drivers of the pedestrian crossing, and visibility to the crossing

is good.

The proposed outbound heavy vehicle route avoids the uncontrolled right turn movement

onto Donald Street/Griffiths Road.

The traffic volumes generated by the Project are relatively low and can be absorbed by

the surrounding road network without any significant impact on road safety.

Page 73: CONSTRUCTION TRAFFIC AND PEDESTRIAN MANAGEMENT …

GHD | Report for Jemena Gas Networks (NSW) Ltd – Former Newcastle Gasworks (Clyde Street) Remediation Project, 2217312 | 23

5. Management and mitigation measures

The following measures are proposed to reduce the traffic impacts associated with the Project:

A Traffic Control Plan will be prepared in consultation with Newcastle City Council and

implemented as part of the Construction Environmental Management Plan to comply with

Roads and Maritime and Newcastle City Council requirements. The Traffic Control Plan

will include the following:

– Confirmation of haulage routes, including the preferred egress route via Boreas Road

and Broadmeadow Road, to reduce the impact on road safety and road user

convenience compared to other alternatives.

– Site specific traffic control measures (including signage) to manage and regulate traffic

movement, including pedestrians and cyclists.

– Requirements and methods to consult and inform the local community of impacts on

the local road network.

– A response plan for any construction traffic incident or any road incident that may

affect the haulage route.

6. Conclusion

This report assessed the traffic impacts of the proposed remediation of the former Newcastle

Gasworks site in Hamilton North. The key findings are as follows:

Works are expected to occur over a seven month period. Working hours will be Monday-

Friday 7.00 am to 6.00 pm and Saturday 8:00 am- 1:00 pm.

The peak traffic generation will occur for a three-month period during construction of the

capping layer. During this period, the Project will generate approximately 22 light vehicles

and 50 heavy vehicles per day.

The proposed heavy vehicle inbound access route is via Donald Street/Griffiths Road and

Chatham Road. Due to the difficulty in making the right turn movement from Chatham

Road into Donald Street/Griffiths Road and the associated safety risk, an alternative

outbound route for heavy vehicles is recommended. The preferred route is via Boreas

Road and Broadmeadow Road.

Access to the Project area will be via the existing access on Chatham Road. The site

access is expected to operate effectively based on the expected traffic generation and

the existing volumes on Chatham Road.

The sight distance at the site access meets Austroads requirements.

The expected increase in traffic volumes on the surrounding road network can be

absorbed without any significant impact on traffic efficiency.

The increased heavy vehicle volumes on Boreas Road will have some impact on amenity

in this residential street; however, the impact will be limited to a three-month period, and

use of this road will have a reduced impact on road safety and road user convenience

compared to other alternatives.

The increase in traffic volumes on Chatham Road can be absorbed without a significant

impact on amenity.

All parking will be within the Project area, resulting in no impact on surrounding streets.

The Project is not expected to have a significant impact on pedestrians or cyclists.

Subject to the recommendations provided, the Project is not expected to cause any

significant detrimental impact to road safety in the vicinity of the Project area.

Based on the findings of this assessment, and subject to the recommendations provided, the

Project is not expected to result in significant traffic and access impacts.

Tina Thank you for providing opportunity to review the CTMP. I have listed some comments below for your reference: 1) Section 2.1, 3.5: Chatham Road is serviced by Route 12 by Newcastle Transport, not Route 235 by Newcastle Buses. Update CTMP accordingly. 2) Section 3.6: All oversize/overmass heavy vehicle movements to transport materials/equipment to/from site must operate under City of Newcastle (CN) OSOM permit approval. Transport operators must submit OSOM permit applications minimum two weeks in advance of the proposed travel date/s for our review and approval. OSOM movements into/out of site on Clyde Street to occur under traffic control to ensure road safety is not compromised. All traffic control must be conducted under CN’s Road Occupancy Permit (ROP) approval. Section 8.2.1 (TCP 175): Delete ‘Roadwork Ahead’ signs in both directions as no work will be undertaken in road reserve – refer RTA example TCP 195. Signage to be placed at ‘D’ distance. The signage placement must be separately approved under CN’s Road Occupancy Permit (ROP) approval before implementation. Section 8.2.1 (TCP 190): Signage to be placed at ‘D’ distance, refer RTA example TCP 195. Section 8.6: Map showing return route proposes the use of Georgetown Road instead of Broadmeadow Road. Update the map. Regards, Dipen Nathwani | Traffic Engineer City of Newcastle | Infrastructure & Property Assets & Projects | Traffic & Transport T:+61249742663 | E:[email protected]

Driveways (s138 application) - Council would generally require a final development approval for certainty as to the need and location of driveway crossings. However, provided you could provide us the final application documentation and draft conditions of consent we could reasonably begin processing the s138 application. This could be in the form of clearly directing us to the relevant information on Departments website. It is likely that the final approval would be withheld until a development consent has been issued. I advise that the s138 application should be lodged with Council using a 'Type 2' application form, given the complexities of the project (a simple driveway would typically be a 'Type 1' application). Application forms can be found at:

I have liaised with Dipen Nathwani (4974 2663,[email protected]) from the Traffic and Transport Team and advise that Council would be willing to 'review' the latest version, however would not be prepared to 'approve' any CTMP prior to a development consent being issued. From my discussion earlier with David it was clarified that the Department of Planning & Environment are seeking confirmation that consultation has occurred with Council in the development of the CTMP.

When we mentioned that Council’s previous position was that given consent hadn’t yet been granted for the project, Council wasn’t in a position to progress assessment of the driveway applications, formal review of the traffic management plan etc., DP&E were of the view that given draft conditions of consent have now been issued, Council should be able to progress these items. For instance, as Tina calls out below, one of the conditions of consent requires the Traffic Management Plan to be prepared in consultation with Council.

Do not click links or open attachments unless you recognise the sender and are expecting the content or attachment from the sender. Steven, I have been passed on your contact details from David Virtue from Jemena with regards to the above project (also cc’d). As Jemena are getting closer to finalisation of the Depart of Planning approval process, the DoP have released the draft consent conditions for the above project. The following points with regard to council have been raised;

The DoP has encouraged the submission of the driveway applications for both temporary and permanent driveway

o Can you please verify if council will accept the applications at this stage o Application to include Section 138 form & Location Mark-up

Council acknowledgement and approval of the construction traffic management plan o CTMP amendment have previously been made post-EIS exhibition to accommodate councils previous

comments in consultation with Jemena and GHD o A draft CTMP is currently being finalised to include draft consent conditions and will be ready for

submission by the end of the week, is council able to provide a review in 1 week? Can you please provide some input to the above. Should you have any queries, please let me know. Regards,

during the EIS and Response to Submissions stages have been incorporated, but DP&E require us to provide evidence of this consultation – hence our request for Council to review. As project team, we’re hoping that you’d be able to accommodate the below, so we can maximise timing efficiency as we look to mobilise to site in the coming weeks once formal development consent has been received. I’d be happy to coordinate a telecon between FCC/Jemena and Council if that would assist in your understanding? Kind regards,
