1. Introduction

The City Rail Link (CRL) project comprises the construction, operation and maintenance of a 3.4 km underground passenger railway, running between Britomart Station and the North Auckland Rail Line (NAL) in the vicinity of Mt Eden Station. The CRL also involves the construction of two new underground stations at Aotea and Karangahape and the redevelopment of the station at Mt Eden (refer to Figure 1.1). The design and construction of the CRL infrastructure between the Aotea and Mt Eden Stations is being delivered by the Link Alliance.

In June 2020 Auckland Council confirmed the Outline Plan and associated Construction Environmental Management Plan (CEMP) and Delivery Works Plans (DWPs) for the Mt Eden Station main construction works (‘Main Works’). The Main Works included the construction of all station buildings, including the redeveloped Mt Eden Station, ventilation building, walking and cycling over bridges and road bridges for grade separation It also included the public realm reinstatement (PRR) of the area surrounding the Porters Avenue bridge.

This document is an addendum to the Main Works CEMP1 and provides an overarching framework for the management of construction effects associated with the PRR that were not covered in the Main Works CEMP.

Where necessary, this CEMP addendum (the CEMP – PRR addendum) details any further provisions which are required in relation to the PRR works that are not already provided for in the Main Works CEMP. In some instances, it has been appropriate to prepare addendum documents to the respective Main Works DWP also (refer Table 1.1).

Where project details, procedures and protocols are already covered in the Main Works CEMP and are directly applicable to the PRR works, reference is made to the appropriate section of the Main

2. Mt Eden Station Public Realm Works

2.1 Overview of Works

This chapter provides a description of the PRR works, which are not included in the Mt Eden Station Main Works CEMP. This includes both PRR works associated with the Mt Eden Station Precinct and NAL areas (see Figure 2.1). An oversite development (OSD) masterplan has been developed for the CRL construction site at Mt Eden, which is to be delivered by CRLL after the works being undertaken by Link Alliance have been completed. The scope of the works being delivered by the Link Alliance, excludes the OSD area (shaded white in Figure 2.1)

The construction works required to reinstate the permanent aspects of the public space include paving, sealing, tie-in works, stormwater treatment, the installation of street furniture and landscaping. The works will be undertaken in a staged manner commencing as the current construction works are progressively completed (refer Section 2.2).

A description of each of the key activities relevant to this addendum is provided in Section 2.3.

2.2 Construction Staging

The PRR works are divided into ‘stages’ (based on activity for the Mt Eden Precinct, and locations for the NAL area) as illustrated in Table 2.1. Refer to the indicative traffic management plans in Appendix A which shows the construction staging.

2.3 Construction Methodology

2.3.1. Overview

Generally, the PRR works will consist of:

• Construction of new stormwater infrastructure

• Installation of utilities

• Construction of tree pits

• Installation of new road pavement

• Installation of new footpath pavements

• Landscaping works

• Installation of street furniture

2.3.2.

Stormwater Infrastructure

New stormwater catchpits, lines and drains are being installed to capture stormwater runoff from the road and footpaths. The new stormwater infrastructure is within the road carriageway and connects into the existing stormwater network.

8 | Mt Eden Station and Public Realm Reinstatement

Figure 2 1: Staging of public realm works

Stage 2

Stage 3

Stage 1

The stormwater construction works will be staged to construct the main drainage lines, manholes and connections first. Generally, these works start from the downstream connection points and are laid ‘uphill’ to the head of the new drainage line. Once the main drainage lines are completed then the Aco drains, catchpits and leads will be constructed – with the works staged in accordance with the construction phases and associated traffic management (Appendix A)

Plant used for the stormwater works includes small to medium sized excavators, trucks for spoil disposal and importing backfill materials, concrete trucks, compaction equipment (plate compactors and/or small rollers), trench shields and hand tools. Due to the limited space available on the site, materials will be delivered to site as they are required for the construction works.

2.3.3. Utilities

A new network of utilities will be required to service the public realm installations and divert main utilities back into permanent alignments. This will include low voltage for street lighting and fibre and copper communications cabling.

Duct installations will be completed using small to medium sized excavators, trucks for spoil disposal and importing backfill materials, concrete trucks, compaction equipment (plate compactors and/or small rollers), trench shields and hand tools. Due to the limited space available on the site, materials will be delivered to site as they are required for the construction works.

Linked to this utility duct and cable work will be the installation of street lighting and other above ground traffic service installations.

2.3.4. Tree Pits

Several tree pits will also be constructed for new planting installations. Locations of this are provided in the Urban Design DWP. Many of the tree pits are in close proximity to services and in some cases 25mm steel plates are to be installed to provide an additional root barrier between the tree pits and service trenches. During excavation, as utilities are approached, hydro excavation and pothole techniques will be used to expose them. Excavation around the utility will be undertaken, leaving enough material to support it temporarily. Where required, temporary supports will also be installed around the utilities.

Tree pits will be excavated to depth using small to medium sized excavators with the excavation battered to provide a safe working zone. The excavations will be around 1-2m deep.

Additional plant used for the tree pit works includes trucks for spoil disposal and importing backfill materials, compaction equipment (plate compactors and/or small rollers), trench shields and hand tools. Due to the limited space available on the site, materials will be delivered to site as they are required for the construction works.

2.3.5. Road Pavement

Once the substantial below ground works are completed in each area, the road pavement works will commence. Subsoil drains will be constructed along the edges of the road carriageway, followed by the kerb construction, then sub-basecourse and basecourse layers.

Testing will be undertaken on the subgrade, sub-basecourse and basecourse layers during construction to confirm the requirements of the civil specifications and drawings have been achieved.

The pavement material will be placed directly from trucks, and spread and compacted using excavators, graders and plate / roller compactors. The road will be constructed in stages providing the necessary live traffic lanes, vehicle access to properties and maintaining pedestrian and cycle access.

Once the underlying pavement layers are complete, the structural asphalt layers will then be constructed. Specialist asphalt subcontractors will undertake these works using asphalt paving plant. The final 50mm layer of asphalt will not be placed until the final phase of the works. This is to ensure no damage to the final layer and to provide a consistent finish with fewer visible joints. Line marking works will be completed once the final asphalt layer has been placed.

2.3.6. Footpath Pavements

The footpath pavements will commence in an area once the utilities works, tree pits and kerbing have been completed. Footpath pavements generally consist of basecourse layer, reinforced concrete layer and decorative paving layer.

The footpaths will be constructed in phases, with pedestrian access (1.5m wide) and access to properties maintained. The pedestrian routes will generally be kept close to the building walls, but will be moved within the work zone to allow the works adjacent to the buildings to be completed. At all times the pedestrian access routes and live work zones will be separated by appropriate safety barriers (e.g. fencing).

Testing will be undertaken on the subgrade and basecourse layers during construction to confirm the requirements of the civil specifications and drawings have been achieved.

The basecourse material (cement treated aggregate) will be delivered to the worksite as required by trucks and spread and compacted using small excavators, and small roller and/or plate compactors. Concrete delivery for the structural concrete layer will be by truck, with concrete pumps (line or boom) used as required. The concrete layer will be constructed in segments to maintain pedestrian movements and suit the constraints of the site. A watering system shall be used to control dust from the placement of fill and bedding material as well as during compaction.

Decorative paving works will involve cutting and placing stone pavers and mixing and placing of Steintec bedding or similar. A watering system shall be used to control dust from extraction and any cutting operations. A mobile acoustic enclosure shall be used where practicable for any paver cutting. Materials for these works will be kept on site (in limited quantities as required) and mixed and cut to fit in designated areas of the work zone.

2.3.7. Landscaping

Landscaping works consist of planting, including tree planting in the completed tree pits (refer 2.3.4) This will be one of the final activities and will be completed from the adjacent traffic lane, where they are located in the footpath. Trees will be delivered by truck and planted by hand or using a Hiab crane. Surface tree grilles or permeable covering will be installed once trees have been planted.

2.3.8. Street Furniture

Street furniture includes street lighting and signage, traffic signals, seating, rubbish bins, and bicycle racks Foundations and utility connections for these items will be completed during the previous stages of these works. The installation of street furniture will be one of the final activities undertaken in each area.

Street furniture will generally be delivered to site and installed immediately. Installation will be carried out by specialist installers using hand tools, and Hiab crane for lifting larger items.

Commissioning and testing of the electrical items (e.g., streetlights, traffic signals) will be carried out by specialist electricians in accordance with the specifications and local authority requirements.

2.4 Programme

The PRR works are anticipated to commence in January 2022 for the east facing connection, May 2023 for the west facing connection, and May 2023 for the Mt Eden Precinct. PRR works will continue through to the end of 2023/early 2024.

2.5 Hours of Work

Construction hours will be as per those outlined in Section 2.5 of the Main Works CEMP. Works will generally be undertaken Monday to Saturday, 0700 – 1900 hrs. However, certain activities may need to be undertaken outside these hours to minimise traffic impacts or minimise disruption to businesses or residents, such as network utility works where the Network Utility Operator (NUO) requires works to be undertaken at night, or the delivery of large plant.

To maintain pedestrian access to business and properties, night works may be required for the installation of pavers. Night works shall be limited to the placing of pre-cut pavers. Cutting of pavers shall be undertaken during daytime construction hours.

2.6 Site layout and management

Construction materials and laydown areas shall be located within the PRR works areas identified in Figure 2.1 and shall be shifted locally as required for construction staging.

Once the construction of the PRR works is complete, the OSD area will be fenced to the kerb edge and reinstated to the surrounding road levels with a tidy finish of granular fill material.

Key activities within the PRR works areas shall include:

• Liquid waste and solid waste storage and collection (e.g., contaminated water, used chemicals, liquids and slurry from spill clean-up, “slops and slurry” skips) from active work zones

• Asphalt pavement construction equipment

• Fuel storage for pumps, generators etc.

• Use and storage of diesel pumps and compressors

• Use and storage of concrete pumps

• Use and storage of mobile generators

• Concrete breaking

• Storage of construction materials such as steel reinforcing cages, pre-cast concrete elements, geotextiles, formwork (timber and steel), bagged cement, paving materials

• Site offices and construction personnel amenities including portable toilets or similar

• Stormwater/groundwater containment and/or treatment facility

• Vehicle movements between active work zones and construction support areas.

2.7 Site Security, Safety and Public Viewing

There is no change to the protocols for managing security, safety and public viewing outlined in the Mains Works CEMP.

2.8 Site Housekeeping

There is no change to the site housing keeping protocols outlined in the Main Works CEMP.

3. Social and Environmental Management

3.1 Construction Activities and Associated Environmental Receivers

The key construction activities associated with the PRR Works are summarised in Table 3.1 below. These activities have the potential to generate adverse environmental effects relating to network utility disruption, social and business disruption, transport access and parking, noise and vibration, dust, stormwater discharges, soil contamination, and built heritage.

Table 3.1. Construction activities and associated environmental receivers

Main activities

- Backfilling

- Spoil handling

- Reinstatement

- Installation of utilities

- Installation of tree pits

- Planting of trees

- Construction of pavements

- Installation of street furniture

3.2 Environmental Risk Register

Receiving Environment

- Stormwater (Waitemata Harbour)

- Buildings (vibration/heritage)

- Residents/social and businesses (noise/vibration/dust/odour)

- Traffic network

There is no change to the risk register framework outlined in Section 3.2 of the Main Works CEMP. It is noted that as the risk register is a ‘living document’ and shall continue to be reviewed monthly as part of the Project Monthly Report and prior to the commencement of new construction activities, such as the PRR works.

3.3 Cumulative Effects

There is no change to the existing approach, whereby sub-plans are relied upon for identification, controls, and monitoring to address cumulative effects. Additional controls are specified in Section 5 of this CEMP.

3.4 Legislative and Other Requirements

There is no change to the identified legislation, polices, plans and consents in Section 3.4 of the Main Works CEMP.

4. Implementation and Operation

The PRR works will be undertaken in accordance with Section 4 of the Main Works CEMP. Specifically, there is no change to the roles and responsibilities, or the environmental and sustainability training and induction procedures outlined in the CEMP.

5. Environmental Management

The Main Works DWPs and Management Plans continue to detail the controls and measure for each on the environmental aspects of the PRR works as specified in Section 5 of the Mains Works CEMP. Furthermore, the following sections identify the environmental aspects associated with the construction of the PRR works with any additional operational controls and mitigation measures specific to the PRR works identified.

5.1 Network Utilities

Consultation and co-ordination with Network Utility Operators will continue to be managed in accordance with the general processes outlined in Section 5.1 of the Main Works CEMP.

5.2 Social Impact and Business Disruption

The PRR works will not change the level of potential adverse social or business disruption effects from the activities identified in the Social Impact Business Disruption (SIBD DWP). In addition, the potential effects of the PRR works don’t extent beyond the ‘affected community’ identified in the Main Works SIBD DWP.

A such, there is no change to the general processes for managing social impacts and business disruption (SIBD) as identified in Section 5.2 of the Main Works CEMP, with additional mitigation to be implemented as outlined in this CEMP Addendum

5.3 Communication and Consultation

There is no change to the general processes outlined in the Communication and Consultation Plan (CCP) for to ensure appropriate communication and consultation with the community, stakeholders, affected parties and affected in-proximity parties occurs during the PRR works as identified in Section 5.3 of the Main Works CEMP.

5.4 Erosion and Sediment Control

There is no change to the general processes for managing erosion and sediment generation as identified in Section 5.4 of the Main Works CEMP.

The Main Works Erosion and Sediment Control Plan (ESCP) follows the principles of Auckland Council GD05. Erosion and sediment control measures will be installed prior to the start of any land disturbance works. The mitigation measures will remain in place until reinstatement of active working areas is complete. General ESC measures include:

• Clean water diversions (install to divert runoff from external catchments entering construction areas e.g., hotmix diversion bunds);

• Stabilised entrance and surface (vehicle movements on sealed surfaces, vehicle accesses to be kept clean, stabilise entrance ways using aggregates).

• Wheel washes to be installed at the exit of CSAs

• All material removed from or delivered to the project site should be covered during transportation to prevent discharges of dust or spillages.

A Flocculant Treatment Management Plan (FTMP) has been prepared as part of the Mains Works ESCP. PRR works will be undertaken in accordance with the measures identified in the FTMP.

5.5 Air Quality

The main discharges to air that will arise from the PRR works is dust. The following dust generating activities associated with the PRR works have been identified:

• Breaking up and excavating the existing footpath;

• Placement of granular material;

• Excavation of tree pits;

• Cutting of pavers/kerbstones;

• Concrete cutting; and

• Placement of soil

Apart from the cutting of pavers and concrete as described below, the other activities will be undertaken in accordance with Section 5.5 of the Main Works CEMP and the Air Quality (AQ) Delivery Work Plan.

5.5.1. Mitigation measures

The dust prevention methods outlined in Table 5.1, will be used as applicable to control dust emissions from the cutting of pavers and curb stones, in all areas of the Project. The list is not exhaustive and additional methods which are found to be effective may be used.

Some of the particulate generated by the cutting of pavers and kerbstones has the potential to be respirable quart/crystalline silica which, when uncontrolled, presents some health risks. These risks are controlled through the mitigation proposed in Table 5.1.

Source of Dust Control

Pavement Removal

Placement of Granular Material

Cutting of Pavers

- Use water as necessary to control dust from extraction and any cutting operations.

- As far as practical excavated material is to be loaded directly into trucks.

- Use water as necessary to control dust from the placement of granular material as well as during compaction.

- As far as practicable all pavers and curb stones will be cut using equipment fitted with water dust suppression.

- Where it is not possible to use water suppression vacuum extraction systems shall be fitted to the cutting/grinding equipment.

- Solid barriers can also be placed around cutting activities to minimise wind effects.

- Alternatively, enclosures may be required (to mitigate noise).

Monitoring of these dust generating activities will be in accordance with the requirements of the AQ DWP. This includes daily visual inspections, or more frequently if conditions change

5.6 Trees and Vegetation

There is no change to the existing processes for managing potential adverse effects on trees and vegetation as identified in Section 5.6 of the Main Works CEMP.

Table 5.1: Dust management methods for PRR pavement works

It is noted no further trees are proposed to be removed as part of the PRR works, however protocols are relevant to existing trees to ensure they are appropriately protected during works. This includes the scheduled Erythrina x sykesii (Flame Tree), located at the southeast corner of the Normanby Road and Boston Road roundabout

All trees that have been permanently removed as part of the early works and main works for Mt Eden Station are to be replaced as part of the PRR works. This is addressed in the Urban Design DWP

5.7 Transport, Access and Parking

A Transport Access and Parking DWP Addendum (Appendix B) has been prepared to specify the methodology during the PRR works. The addendum identifies the transport configurations (including traffic layouts and movements, pedestrian access, property access and parking) for each of the construction configurations of the PRR works.

An overview of the traffic management stages is summarised below.

Stage Road Network Layout (General)

Stage 1 (A-I) Normanby Road/Boston Road/Nugent Street

In Stages 1A, 1B and 1C, the intersection will be controlled by a small temporary roundabout. Normanby Road will remain closed at the Boston Road / Nugent Street intersection and traffic operations at the intersection are expected to remain as they were since the closure of the Normanby Rd level crossing.

Stages 1G, 1H and 1I all operate using temporary traffic signals on Normanby Road to maintain two-way access for Normanby Road, Lauder Road, 32 Normanby Road and 51-63 Normanby Road.

Pedestrian movements between Boston Road and Nugent Street will be provided on footpaths (existing or new) or protected walkways between the work areas.

Stage 2 (A-C) Fenton Street/Wynyard Street2

One vehicle lane will be maintained adjacent to the work sites on Wynyard Road and Porters Avenue, and on the approaches from Haultain Street and Fenton Street. Temporary traffic signals and Stop/Go controls will be used to control two-way vehicle movements over the one traffic lane, particularly the movements between Wynyard Road and Haultain Street, Wynyard Road and Fenton Street, and Porters Avenue and the rear carpark of 1 Porters Avenue.

Pedestrian movements between Wynyard Road and Haultain Street are maintained via the eastern footpath of Wynyard Road and a protected pedestrian pathway adjacent the NAL tracks between Fenton Street and Haultain Street. The western footpath on Wynyard Road adjacent the work site will be closed.

2 The public realm reinstatement of Porters Ave and Haultain Street formed part of the Mt Eden Main works Outline Plan. As such, it does not form part of the PRR extent of works as identified in Figure 2.1. However, for completeness, it is considered appropriate to provide detail of the traffic management methodology related to this stage, since these works occur concurrently

17 | Mt Eden Station and Public Realm Reinstatement

Table 5.2: Overview of the road network layout, access and relationship between PRR stages PRR

PRR Stage Road Network Layout (General)

Existing on-street parking restrictions along the full length of Haultain Street and Fenton Street, and for parts of Wynyard Road and Porters Avenue will remain in place until the PRR works are completed.

Stage 3 Mt Eden Precinct (A-E)

During Stage 3A the road connection from Ruru Street to Nikau Street will remain operating with a one-way lane arrangement. Pedestrian movements will be maintained on the northern side of Nikau Street and the eastern side of Ruru Street adjacent the works area.

During Stage 3B the section of Nikau Street between Korari Street and Flower Street will be closed to through traffic but available to vehicles for property access. Korari Street will operate as a cul-de-sac road. Pedestrian movements will be maintained on the northern side of Nikau Street in the same way as in Stage 3A.

During Stage 3C and 3D Flower Street will need to operate as one lane with two-way movements on the realigned road section controlled by temporary traffic signals. Pedestrian movements will be maintained on the northern footpath of Nikau Street and the eastern footpath of the realigned section of Flower Street.

During Stage 3E two-lane northbound movements across the Mt Eden Road bridge will be maintained. One-lane for southbound movements is maintained. Pedestrian movements are maintained on the eastern side of the bridge.

Site-specific Traffic Management Plans (TMP) will be developed approximately one month before the commencement of works in accordance with the CRL designation conditions, and Waka Kotahi’s Code of Practice for Temporary Traffic Management (CoPTTM).

Pedestrian and cyclist access to properties will be maintained at all times as required by designation conditions 25.2(b) and 25.3(f)(i). On-going vehicle access to properties will be maintained to the greatest extent possible as required by designation conditions 25.2(c), 25.3(f)(ii) and 25.3(g).

The processes and responsibilities in relation to monitoring for the PRR works are consistent with that for the Main Works, as detailed in Section 6 of the Main Works TAP DWP

Together with the specific measures to manage the PRR work set out in the TAP DWP - PRR Addendum and the general management measures in the TAP DWP, adverse transport, access and parking effects will be appropriately mitigated.

5.8 Construction Nose and Vibration

Construction noise and vibration will continue to be managed in accordance with the general processed for managing construction noise and vibration as outlined in the Main Works CNV DWP and the Site Specific Construction Noise and Vibration Management Plans, as appropriate.

The CNV DWP – PRR Addendum states that the mitigation and management measures outlined in Section 9 of the CNV DWP as well as the SSCNVMPs in Appendix C are appropriate and sufficient for the PRR works. No new mitigation or management measures are required.

However, one new SSCNMP may be required, in accordance with condition 37.2 for 27 Boston Road. This is for pavement re-instatement works that could be up to 75 - 80 dB LAeq for brief times. If works are greater than two weeks than an SSCNMP will be required. This has been prepared and is attached to the CNV DWP – PRR Addendum.

5.9 Lighting Spill and Glare

There is no change to the existing processes for managing construction lighting as identified in Section 5.9 of the CEMP.

5.10 Historic Character

5.10.1.

Built Heritage

The PRR works has the potential to affect historic buildings and historic streetscape elements, as identified in the Mt Eden Station Main Works Historic Heritage DWP – Built Heritage.

The PRR works will be undertaken in accordance with Section 5.10.1 of the Main Works CEMP and the general management measures outlined in the Historic Heritage DWP – Built Heritage. This includes methods to monitor the works (as set out in the CNV DWP, SSCNVMP and GSMCP) and to protect heritage fabric during construction phases. This includes the use of plywood to protect building fabric, use of bracing for parapets, chimneys etc and careful removal of basalt kerbs for reuse.

Protection measures shall be reviewed by the Project Built Heritage Specialist prior to works commencing and periodically during the works.

5.10.2. Archaeology

The PRR works will be undertaken in accordance with Section 5.10.2 of the Main Works CEMP and the general management measures outlined in the Historic Heritage DWP – Archaeology.

As described in Section 5.10.2 of the Main Works CEMP there are three recorded archaeological sites within the main works area (already addressed in the Mt Eden Enabling Works DWP3), namely:

• R11/51: a shell midden site related to Māori settlement, recorded in the 1960s near the railway lines and within 31 Ruru Street, but subsequently destroyed by development works (Enabling Works).

• R11/3079: a pre-1900 building and any associated subsurface remains at 31 Shaddock Street. The building was demolished prior to the Mt Eden Enabling Works.

• R11/3080: a pre-1900 building and any associated subsurface remains located at 6 Flower Street. The building was removed prior to the Mt Eden Enabling Works.

Two additional recorded sites fall within the area, namely:

• Mt Eden railway station platform is recorded on Auckland Council’s Cultural Heritage Inventory. The original platform has been partially removed and the platform raised, but part of the original 1912 island platform will still be present beneath the existing platform surface. The platform will not be affected as part of the PRR works.

• Mt Eden Prison (R11/2408). The old prison wall is located immediately adjacent to the NAL railway corridor. Any potential vibration effects on the wall will be addressed in the HC DWP (Built Heritage), refer section 5.10.1 and Appendix M of this CEMP

The PRR works will result in shallow excavations only and is unlikely that subsurface archaeological remains will be exposed. However, the possibility that subsurface pre-1900 or early 20th century

3 Mt Eden Enabling Works Historic Character Delivery Work Plan (Archaeology Section), Revision 000, November 2019, CRL-MTE-RME-LKA-PLN-800018.

archaeological remains may be exposed during the PRR phase will be mitigated and managed through the implementation of the HCC DWP (Archaeology Section) and an Archaeological Authority (no. 2017/793) granted by Heritage New Zealand Pouhere Taonga (HNZPT) for the wider CRL project (“the HNZPT Authority”)

Measures to mitigate impacts on archaeological remains include:

• Archaeological Discovery Protocols;

• Mana Whenua Protocols;

• Recording of Features and Deposits;

• Artefact Management Plan;

• Stand down periods;

• Post-excavation analysis and archiving; and

• Reporting requirements.

5.11 Urban Design

An Urban Design Delivery Work Plan (Urban Design DWP) has been prepared by the PRR works and the design of the Mt Eden Station including entrances and associated buildings. The Urban Design DWP is required to ensure that the areas within the designation footprint used during construction are restored and permanent works associated with the CRL are developed in accordance with urban design principles.

5.12 Contaminated Soils

The existing management approach to the disturbance of any contaminated, or potentially contaminated material encountered during the PRR work, and the management of any associated human health or environmental effects will be undertaken in accordance with Section 5.12 of the Main Works CEM and the Main Works Contamination DWP.

5.13 Groundwater and Settlement

Due to the shallow nature of excavations required for the PRR works, groundwater is not expected to be encountered. As stated in the Assessment of Settlement Effects Report4 , a GSMCP is not required for the PRR works.

If groundwater is encountered, groundwater and settlement monitoring will be undertaken in accordance with the Main Works GSMCP.

5.14 Hazardous Substances

Hazards substances will be kept on site within specified bunded enclosures, within the CSAs. No additional hazardous substances will be required for the PRR works, from that listed in the Main Works CEMP.

The storage and use of hazardous substances will be managed in managed in accordance with Section 5.14 of the Main Works CEMP and the relevant provisions of the Industrial and Trade

Activities Environmental Management Plan (ITA EMP). Any spills on site will be managed in accordance with the General Spill Response Plan provided as Appendix C to the ITA EMP.

5.15 Industrial and Trade Activities

Industrial trade activities will be managed in accordance with Section 5.15 of the Main Works CEMP and the relevant provisions of the Industrial and Trade Activities Environmental Management Plan. This includes activities such as vehicle refuelling, concrete washout, and the management of hazardous substances. Any spills on site will be managed in accordance with the General Spill Response Plan provided as Appendix C to the ITA EMP.

5.16 Building Condition Surveys

Building condition surveys (BCS) were required to be undertaken prior to the Main Works construction phase commencing, in accordance with designation condition 46 and resource consent condition 109. Due to the shallow nature of excavations required, no additional building condition surveys are required prior to the commencement of the PRR phase of works.

Post construction condition survey requirements will be undertaken as identified in Section 5.16 of the Main Works CEMP.

5.17 Waste Management

There is no change to the existing processes for waste management as identified in Section 5.18 of the Main Works CEMP.

5.18 Energy Use

There is to change to the existing processes for reducing energy use as identified in Section 5.19 of the Main Works CEMP.

5.19 Water Use

There is to change to the existing processes for reducing water use as identified in Section 5.20 of the Main Works CEMP.

5.20 Material Use

1. Introduction

This addendum to the Mt Eden Main Works Transport Access and Parking Delivery Work Plan (TAP DWP)1 has been prepared to address any potential effects associated with the public realm reinstatement works (PRR) phase of construction works

This addendum should be read in conjunction with the Mt Eden Main Works TAP DWP. Where project details, proposed management and effects are already covered in the Mt Eden Main Works TAP DWP and are directly applicable to the PRR works, reference is made to the appropriate section of that document.

2. Project Description

This section presents a summary of the PRR works to provide context to the TAP DWP Addendum. A detailed description of the PRR works is provided in the Mt Eden PRR Construction Environmental Management Plan (CEMP) Addendum. Further detail on the PRR works is also provided in the Mt Eden Station Urban Design Delivery Work Plan (Urban Design DWP)

1 Mt Eden Main Works Transport Access and Parking Delivery Work Plan, Rev 001A, prepared by the Link Alliance, dated 14 July 2020

Figure 1.1 CRL Route and Location

2.1 Construction Methodology Overview

The extent of the PRR works is shown in Figure 2.1 and includes the Mt Eden Precinct and eastern and western facing connections. An oversite development (OSD) masterplan has been developed for the CRL construction site at Mt Eden which is to be delivered by CRLL after the works being undertaken by Link Alliance have been completed. The scope of the works being delivered by the Link Alliance, excludes the OSD area (shaded white in Figure 2.1).

The construction works required to reinstate the permanent aspects of the public space include paving, sealing, tie-in works, stormwater treatment, the installation of street furniture and landscaping. The works will be undertaken in a staged manner as the current construction works are progressively completed. Refer to the CEMP Addendum for a further detailed description of the works.

The PRR works are divided into the three ‘stages’ as described Table 2.2 Each stage is a distinct area of activity in the wider Mt Eden Precinct, which includes the NAL work sites.

3. Existing Transport Conditions

The traffic volumes of the roads nearest to where the PRR works will be undertaken are shown in Table 3.1. These volumes were obtained from Auckland Transport (AT) tube counts undertaken in the respective areas.

Table 3.1 Traffic volumes on main roads adjacent PRR works

Estimated volumes for July 2020 onwards with the closure of Porters Ave level crossing

* These vehicle volumes are based on the 2015 survey data with a 50% reduction applied to account for the demolition of properties that was undertaken to establish the Mt Eden CSA. The CRL transport assessment for the demolition works in the area estimated that a traffic volume reduction of up to 70% can be expected following demolition.

Further details of the existing transport environment are provided in Section 3 of the Mt Eden Main Works TAP DWP.

4. Proposed Traffic Management Methodology

The traffic management methodology has been developed to ensure that the transport functions of private properties and the public road network are maintained in accordance with the CRL designation conditions. Within the works area, the provision of access to private property and the public network for the different transport modes are prioritised in this order:

1. Active transport (pedestrians and cyclists),

2. Public transport,

3. Freight (including service vehicles, couriers and taxis), and 4. Private vehicles

Site-specific Traffic Management Plans (TMP) will be developed approximately one month before the commencement of works in accordance with the CRL designation conditions, this DWP addendum, and Waka Kotahi’s Code of Practice for Temporary Traffic Management (CoPTTM).

A Traffic Resolution approval will be obtained from AT’s Traffic Control Committee to support any TMPs that require changes to on-street traffic and parking controls to be in place for three weeks or more.

The following report sections describes the general traffic management methodology for each stage of the PRR works.

4.1 Normanby Road /Boston Road / Nugent Street – Eastern Facing Connection (Stage 1)

Stage 1 of the PRR works comprise of the installation of the new Normanby Road / Nugent Street / Boston Road roundabout with improvements to the footpath and pedestrian crossing facilities on each approach. Stage 1 also includes services installation, road reinstatement and landscaping (refer Figure 2.1 for the extent of these works).Existing vehicle crossings will be reconstructed as part of the new intersection layout.

The traffic management will maintain two vehicle lanes on each intersection approach in Stages 1A, 1B, 1C with the intersection of Nugent Street and Boston Road controlled by a temporary roundabout, similar to the one installed since the Normanby Road level crossing closure in June 2021 and for the utility diversion works in October 2021.

In Stage 1D, each intersection approach will be reduced to one lane while the intersection is managed by stop/go operations, which are to be undertaken over weekends, during low traffic volume conditions.

Parking restrictions currently in place on both sides of Boston Road between Mount Eden Road and Khyber Pass will remain until the completion of PRR Stage 1.

Stage 1A consists of the construction of the Normanby Road roundabout approach, and new kerb lines and footpath on the southern side of Boston Road. The indicative traffic management layout is shown in Figure 4.1

Figure 4.1 – Indicative traffic management layout for Stage 1A

Pedestrian movements along the northern side of Boston Road will be maintained, and a crossing point will be provided on Nugent Street. Non-mobility pedestrian movements between Boston Road and Normanby Road are provided for via the temporary pedestrian and services bridge. Vehicle access to private properties in the vicinity of the works will be maintained at their existing vehicle crossings.

Stage 1B consists of construction of the north-eastern corner of the new intersection, including pedestrian splitter islands, vehicle crossings, kerb lines and footpaths. The indicative traffic management layout is shown in Figure 4.2

Pedestrian access to private properties on the north-eastern intersection corner will be provided adjacent the work sites. However, pedestrian movements between Boston Road and Nugent Street at the intersection will use the footpath on the northern side of Boston Road and the western side of Nugent Street. Vehicle access to private properties within the work site will be maintained.

Stage 1C consists of construction of the new kerb lines, footpath and vehicle crossings on the northwestern corner of the intersection. The indicative traffic management layout is shown in Figure 4.3

Figure 4 2 – Indicative traffic management layout for Stage 1B

Pedestrian access to private properties on the north-western intersection corner will be provided, however, public pedestrian throughfare between Boston Road and Nugent Street at the intersection will be provided for on the southern side of Boston Road and eastern side of Nugent Street. Vehicle access to private properties within the work site will be maintained.

Stage 1D consists of the construction of the new roundabout central island, pedestrian splitter island on the western approach of the intersection to be undertaken under weekend works. The indicative traffic management layout is shown in Figure 4.4

Figure 4 3 – Indicative traffic management layout for Stage 1C

4 4 – Indicative traffic management layout for Stage 1D

This stage requires a temporary relocation of the Boston Road bus stops to no. 2 Boston Road, the same location used during the October 2021 utility diversion works. Pedestrian footpaths will be maintained through the intersection, and vehicle and pedestrian access to private properties will be maintained at all times. Stop/go operations will be in place to facilitate two-way vehicle movements over one lane through the intersection.

Stage 1E consists of PRR works on the southern side of Boston Road between Nugent Street and Auburn Street, limiting the section to a single lane for eastbound movements The indicative traffic management layout is shown in Figure 4.5

Figure

Two-way movements will be maintained on Nugent Street and the west approach of Boston Road at the Boston Road/Nugent Street intersection. The westbound movements of the 64 bus service that use this section of Boston Road will be rerouted via Khyber Pass Road and Nugent Street, similar to an arrangement previously adopted in October 2020 Pedestrian movements and vehicle access along the northern side of Boston Road will be maintained.

Stage 1F consists of the PRR works on the northern side of Boston Road between Nugent Street and Auburn Street. The indicative traffic management layout is shown in Figure 4.6.

Figure 4 5 – Indicative traffic management layout for Stage 1E

Similar to Stage 1E, this stage includes a one-way arrangement in the eastbound direction between Nugent Street and Auburn Street. Pedestrian movements, access and vehicle access for properties along the northern side of Boston Road will continue to be maintained. The westbound direction of the 64 bus service will be rerouted as described for Stage 1E.

Stage 1G includes PRR work to the south of the new Normanby Road bridge over the NAL The indicative traffic management layout is shown in Figure 4.7

Figure 4.6 – Indicative traffic management layout for Stage 1F

This stage limits the property accesses on Lauder Road and property no. 32 to one vehicle lane. However, two-way access will be maintained, and the vehicle movements will be operated using temporary traffic signals.

Pedestrian movements along Lauder Road will be maintained using the southern footpath and pedestrian access would be maintained between Normanby Road and Boston Road for non-mobility impaired users via the pedestrian footbridge.

The indicative traffic management layout for Stage 1H is shown in Figure 4.8

Figure 4 7 – Indicative traffic management layout for Stage 1G

4 8 – Indicative traffic management layout for Stage 1H

This stage includes a two-way arrangement over one lane on Normanby Road and Lauder Road. Normanby Road, Lauder Road, 32 Normanby Road and 51-63 Normanby Road will be operated using temporary traffic lights to maintain two-way access. Pedestrian movements and access to properties is similar to Stage 1G

The existing on-street parking restrictions on Normanby Road will remain in place until the end of Stage 1 to support the PRR works.

The indicative traffic management layout for Stage 1I is shown in Figure 4.9

Figure

Figure 4 9 – Indicative traffic management layout for Stage 1I

Similar to Stage 1H, this stage continues to use temporary traffic lights to maintain two-way access for Lauder Road, 32 Normanby Road and 51-63 Normanby Road. Due to the footpath closure on the western side of Normanby Road, pedestrian access would be maintained via the eastern side of Normanby Road and Lauder Road.

4.2 Fenton Street / Wynyard Road – Western Facing Connection (Stage 2)

Stage 2 of the PRR works comprise the installation of new pavement, kerb lines, footpath and landscaping on Fenton Street, Wynyard Road, Porters Avenue and Haultain Street2. Existing vehicle crossings will be reconstructed as part of the new road layouts.

Stage 2A comprises of work on Wynyard Road and Porters Avenue. The indicative traffic management layout is shown in Figure 4.10.

2 The public realm reinstatement of Porters Ave and Haultain Street formed part of the Mt Eden Main works Outline Plan. As such, it does not form part of the PRR extent of works as identified in Figure 2.1. However, for completeness, it is considered appropriate to provide detail of the traffic management methodology and an assessment of traffic effects related to this stage, since these works occur concurrently

4 10 – Indicative traffic management layout for Stage 2A

Stage 2B includes works on the northern side of Haultain Street and continues with works on Wynyard Road and Porters Avenue. The indicative traffic management layout is shown in Figure 4.11.

Figure

4 11 – Indicative traffic management layout for Stage 2B

Similar to Stage 2A, one vehicle lane will be maintained on each approach to the works area, and their intersections will be controlled by Stop/Go and temporary traffic signals. Diversions of pedestrian movements in the area will be the same as in Stage 2A.

The indicative traffic management layout for Stage 2C is shown in Figure 4.12.

Figure

Similar to the previous stages, Stage 2C will maintain two-way vehicle movements over one-lane on all roads using Stop/Go and temporary traffic signals. The pedestrian movement diversions will be also the same as the previous stages.

4.3 Mount Eden Precinct – Nikau Street between Ruru Street and Shaddock Street (Stage 3)

Stage 3 of the PRR works comprise of the drainage, utility, roading and streetscape works surrounding the Mt Eden Station precinct. The existing on-street parking restrictions on Nikau Street and Ruru Street will remain in place until the end of Stage 3B to support the PRR works.

Stage 3A involves the installation of stormwater drainage along Ruru Street and Nikau Street. The indicative traffic management layout is shown in Figure 4.13.

Figure 4 12 – Indicative traffic management layout for Stage 2C

The road connection from Ruru Street to Nikau Street will remain operating with a one-way lane arrangement. The one-way movements on Nikau Street will be provided a Stop control at Korari Street. Pedestrian movements will be maintained on the northern side of Nikau Street and the eastern side of Ruru Street adjacent the works area.

Stage 3B involves roading works on Ruru Street and Nikau Street. The indicative traffic management layout is shown in Figure 4.14.

Figure 4 13 – Indicative traffic management layout for Stage 3A

Figure 4 14 – Indicative traffic management layout for Stage 3B

Similar to Stage 3A, a one-way lane arrangement will be in place on Nikau Street between Ruru Street and Korari Street.

The section of Nikau Street between Korari Street and Flower Street will be closed to through traffic but available to vehicles for property access. Korari Street will operate as a cul-de-sac road. This arrangement on the three roads had been adopted for utility diversions works between May and November 2021.

Pedestrian movements will be maintained on the northern side of Nikau Street in the same way as in Stage 3A.

The indicative traffic management layout for Stage 3C with the works on Flower Street is shown in. Figure 4.15.

4 15 – Indicative traffic management layout for Stage 3C

Stage 3C consists of utility works along the western side of Flower Street south of Nikau Street, with the work site extending into Shaddock Street and Nikau Street at each end.

Flower Street will need to operate as one lane with two-way movements on the realigned road section controlled by temporary traffic signals. The signals will coordinate vehicle movements at the intersection of Nikau Street and Flower Street as well as the property vehicle access to no. 10 Flower Street.

Pedestrian movements will be maintained on the northern footpath of Nikau Street and the eastern footpath of the realigned section of Flower Street.

The indicative traffic management layout for Stage 3D is shown in Figure 4.16.

Figure

4 16 – Indicative traffic management layout for Stage 3D

Stage 3D consists of the final streetscape works with a work area along the eastern side of Flower Street and part of the southern side of Nikau Street between Flower Street and Mount Eden Road. The intersection of Nikau Street and Flower Street will continue to operate with temporary traffic signals, coordinating with the no. 10 Flower Street vehicle access. Pedestrian movements on Flower Street, south of Nikau Street, will continue to use the eastern footpath adjacent the worksite while two-way vehicle movements

Stage 3E includes the works on the eastern edge of the Mt Eden Station Precinct, at the connection to Mt Eden Road The indicative traffic management layout for this stage is shown Figure 4.17

Figure

Figure 4 17 – Indicative traffic management layout for Stage 3E

This stage maintains two-lane northbound movements across the Mt Eden Road bridge. One-lane for southbound movements is maintained Pedestrian movements are maintained on the eastern side of the bridge. This arrangement for Mt Eden Road between Boston Road and Enfield Street was installed in May 2021 following modelling assessment and consultation with AT and will continue to remain in place for the completion of the PRR works.

It should be noted that the majority of the PRR works in Stage 3 for the Mt Eden Station Precinct will be undertaken with the existing main Construction Support Area (where the CRL tunnel portable is established) The works require no changes to the wider transport network

5. Assessment and Management of Effects

The indicative TMPs and this assessment of effects will be further supplemented by site-specific TMPs which will be submitted to AT for approval in due course. AT will have final discretion over the anticipated transport effects of the TMPs. Further discussion will be required with AT and Auckland Council to resolve any inconsistencies between traffic management measures and designation conditions

5.1 Stage 1 – Normanby Road / Boston Road / Nugent Street

5.1.1. Network Operational Effects

In Stages 1A, 1B and 1C, the intersection will be controlled by a small temporary roundabout, approximately 6m in diameter, marked by flexi-posts and roundabout chevron signs. This roundabout will be similar to the existing temporary roundabout that was installed in June 2021 for

the closure of the Normanby Road level crossing and will be shifted for the PRR stages to accommodate the location of the work sites. Normanby Road will remain closed at the Boston Road / Nugent Street intersection and traffic operations at the intersection are expected to remain as they were since the closure of the Normanby Rd level crossing.

Stages 1E and 1F continue to use a small temporary roundabout. During these stages Boston Road between Nugent Street and Auburn Street will be operating under a one-way arrangement in the eastbound direction. Since the closure of the Normanby Road level crossing in June 2021, the eastbound traffic flows on Boston Road have been observed to be more dominant than the westbound direction. This is consistent with previously surveyed traffic volumes and supports the continued adoption of diverting westbound movements to Khyber Pass Road and Nugent Street.

The two-way over one-lane traffic operations in Stage 1D will be in place during the weekends when traffic volumes have been shown to be 56% of the weekday average volumes. It has been observed that since the closure of Normanby Road level crossing, the dominant traffic flows at the intersection are the Boston Road eastbound movements from Mt Eden Road to Khyber Pass and southbound movements right turn from Nugent Street to Boston Road. The intersection will be managed by Stop/Go traffic controllers who will ensure that traffic queues do not exceed the available queuing distances on each approach. Stop/Go control has been previously used at this intersection on several occasions in 2021, particularly on weekends and during the 9am – 3pm interpeak period in January, July and October 2021.

Stages 1G, 1H and 1I all operate using temporary traffic signals on Normanby Road to maintain twoway access for Normanby Road, Lauder Road, 32 Normanby Road and 51-63 Normanby Road The two-way lane arrangement over one-lane on Normanby Road between 22 and 32 Normanby Road similar to Stage 1H and 1I will be implemented in November 2021 for utility diversion works. This is anticipated to have a minimal impact in the area due to the low traffic volumes as a result of the closure of the level crossing, making Normanby Road effectively a cul-de-sac at the northern area.

The construction traffic volumes estimated for Stage 1 are in the order of 30-40 vehicle movements per day (either entry or exit), distributed over a 10 hour working day, and is anticipated to have negligible impacts on the network

5.1.2. Pedestrian and Cyclist Access

Pedestrian and cyclist access to properties will be maintained at all times as required by designation conditions 25.2(b) and 25.3(f)(i). Pedestrian movements between Boston Road and Nugent Street will be provided on footpaths (existing or new) or protected walkways between the work areas. The specific pedestrian diversions for each stage are shown in Figure 4.1 to Figure 4.8

Non-mobility impaired pedestrians will be able to use the temporary pedestrian footbridge to move between Boston Road and Normanby Road.

No cycling facilities exist in the Stage 1 works area. Cyclists are expected to continue to use the traffic lane.

5.1.3. Property Access

The Stage 1 works are anticipated to impact vehicle access to the following properties:

• 18 Nugent Street (Stage 1B)

• 55 Boston Road (Stage 1B)

• 57 Boston Road (Stage 1B, 1E and 1F)

• 65 Boston Road (Stage 1C)

• 67 Boston Road (Stage 1C)

• 39 Nugent Street (Stage 1C)

• 27-49 Boston Road (Stage 1E and 1F)

• 32 and 32A Normanby Road (Stage 1G, 1H, 1I)

• 51-63 Normanby Road (Stage 1G, 1H, 1I)

• Lauder Road

On-going vehicle access to properties will be maintained to the greatest extent possible as required by designation conditions 25.2(c) and 25.3(f)(ii) and 25.3(g).

Additionally, two-way access will be maintained at all times for vehicles accessing Lauder Road, 32 Normanby Road and 51-63 Normanby Road as required by designation conditions 30.1(h), 30.1(i) and 30.1(j)

5.1.4. Public Transport Impacts

The operations of the 64 bus service on Boston Road in Stages 1A to 1C are expected to be no different to the existing situation since the closure of Normanby Road level crossing in June 2021.

The weekend Stop/Go operations in Stage 1D are expected to impact the 64 bus service on Boston Road. The effects on bus journey times are not expected to be significant and can be mitigated by actively prioritising the Boston Road traffic movements whenever a bus is observed approaching the intersection. AT Metro will be notified of the Stop/Go arrangement and no negative feedback have been received from the previous uses of this arrangement, as mentioned above.

The bus stops on Boston Road west of Nugent Street will be temporarily relocated to no. 2 Boston Road in Stage 1D.

During Stages 1E and 1F the westbound direction of the 64 bus service on Boston Road will need to divert to Khyber Pass Road and Nugent Street. This will not impact pedestrian access to the service from the Boston Road bus stops located to the west of the Boston Road/Nugent Street roundabout.

5.1.5. Public Parking and Loading

No stopping parking restrictions are in place along the full length of Boston Road between Mount Eden Road and Khyber Pass Road, and on both sides of Normanby Road between Lauder Road and 49 Normanby Road. Therefore, no additional parking or loading zone removal is needed on Boston Road and Normanby Road for the PRR works

Approximately three on-street parking spaces on Nugent Street outside 18 Nugent Street will be temporarily removed by the Stage 1B works. No on-street loading zones are impacted in Stage 1.

5.2 Stage 2 – Fenton Street / Wynyard Road

5.2.1.

Network Traffic Operation Effects

A temporary traffic signal arrangement has been in place on Wynyard Road, Fenton Street, Haultain Street and Porters Avenue since July 2020 to control two-way vehicle movements over one-lane adjacent the existing CRL work sites. Since the permanent closure of the Wynyard Road-Porters

Avenue level crossing in July 2020, traffic volumes on Wynyard Road and Porters Avenue have been reduced to only local traffic and there has been minimal impact on access to the local properties.

There have been no traffic operational issues reported with the use of temporary signals to management the vehicle movements on these roads. The continued use of the signals during the PRR Stage 2 works is not expected to yield additional operational impacts.

The construction traffic volumes estimated for Stage 2 are in the order of 10 vehicle movements per day and is anticipated to have negligible impacts on the network.

5.2.2. Pedestrian and Cyclist Effects

Pedestrian and cyclist access to properties will be maintained at all times as required by designation conditions 25.2(b) and 25.3(f)(i).

No cycling facilities exist in the Stage 2 works area. Cyclists are expected to use the road to access the area.

The localised diversions for pedestrian movements between Haultain Street and Wynyard Road will require pedestrians to travel an additional 80m or about one minute of walking.

5.2.3. Property Access

The Stage 2 works are anticipated to impact vehicle access to the following properties:

• 1 Fenton Street (Stage 2B)

• 1A, 1B, 1C Wynyard Road (Stage 2C)

• 2 – 12 Haultain Street (Stage 2C)

• 5 Porters Avenue (Stage 2C)

• 2, 4 and 6 Porters Avenue (Stage 2C)

• 148 New North Road (Stage 2C)

On-going vehicle access to properties will be maintained to the greatest extent possible as required by designation conditions 25.2(c), 25.3(f)(ii) and 25.3(g).

5.2.4. Public Parking and Loading

Permanent no-parking lines have been resolved on both sides of Haultain Street, Fenton Street, Porters Avenue and on parts of the Wynyard Road to support the CRL main works. No additional onstreet parking or loading zone will be lost in the PRR Stage 2 works.

5.3 Stage 3 – Mt Eden Precinct

5.3.1.

Network Operational Effects

The one-way arrangement for Ruru Street to Nikau Street with and without the closure of Nikau Street to through-traffic between Korari Street and Flower Street has been previously adopted for CRL main works between May and November 2021. The impacts of this arrangement to traffic operations in the area, especially on the adjoining roads of Ruru Street, Korari Street and Flower Street, have been observed to be negligible. There have been no reported traffic operational issues with the use of this arrangement.

The closure of Nikau Street to through-traffic between Korari Street and Flower Street in Stage 3B is not consistent with designation condition 30.1(d), which requires two lanes to be maintained at all times in this road section. The previous implementation of this localised Nikau Street closure in May 2021 was approved through an application to Auckland Council in March 2021 that assessed the construction related reasons for the closure, consideration of alternative options, and assessment of local property and network effects. It is anticipated that a similar approval process will be required to accompany approval of the site-specific TMP for this closure.

The use of temporary traffic signals in Stages 3C and 3D to manage two-way vehicle movements over one-lane on Flower Street is not expected to result in traffic operational issues for the impacted roads. However, given that the one-lane section will be approximately 100m long, vehicle movements related to local property access on Shaddock Street would experience it as a delay compared to existing conditions.

During Stage 3E two northbound lanes and one southbound lane will be operating on Mt Eden Road on the Mt Eden Road bridge. This satisfies designation condition 30.1(a) with the provision of at least one traffic lane in each direction and 30.2(e) which requires that there be no reduction to the number of fully operational traffic lanes on Mt Eden Road Bridge during the closure of Normanby Road.

The construction traffic volumes estimated for Stage 3 are in the order of 20-40 vehicle movements per day during a phase of CRL when the main construction work related traffic accessing the construction site via Ngahura Street is expected to reduce. Overall, it is anticipated to have negligible impacts on the network.

5.3.2. Pedestrian and Cyclist Effects

Pedestrian and cyclist access to properties will be maintained at all times as required by designation conditions 25.2(b) and 25.3(f)(i). Footpaths will be maintained on at least one side of the road and no pedestrian movement diversions are required.

No cycling facilities exist in the Stage 3 works area. Cyclists are expected to use the road to access the area.

5.3.3. Property Access

The following private properties would be affected by work areas in the following sub-stages of Stage 3:

• 10 Ruru Street (Stage 3B)

• 3 Flower Street (Stage 3B)

• 10 Flower Street (Stage 3C and 3D)

On-going vehicle access to properties will be maintained to the greatest extent possible as required by designation conditions 25.2(c), 25.3(f)(ii) and 25.3(g).

5.3.4. Public Parking and Loading

There are existing temporary parking restrictions in place on Nikau Street between Ruru Street and Korari Street to support the one-way eastbound arrangement. These parking restrictions are set to expire on 14 May 2023 and may need to be extended to December 2023 to support the completion of Stage 3B.

Permanent parking restrictions are in place on Ruru Street, Nikau Street and Shaddock Street to support the CRL main works. No additional parking removal is anticipated on these streets for PRR Stage 3.

6. Monitoring

The travel time and congestion monitoring requirements for CRL are set out in designation condition 26. The processes and responsibilities in relation to monitoring for the PRR works are consistent with that for the Main Works, as detailed in Section 6 of the Mt Eden Main Works TAP DWP.

7. Consultation and Communication

The scope of the consultation and communication requirements for PRR works are consistent with that established for the Main Works, as detailed in Section 7 of the Mt Eden Main Works TAP DWP.

The Link Alliance communications and engagement team will work with the construction and traffic management teams to ensure that the requirements set out in this TAP DWP are achieved.

Figure 1.1 CRL Route and Location

2.1 Construction Methodology Overview

The extent of the PRR works is shown in Figure 2.1 and includes the Mt Eden Precinct and eastern and western facing connections. An oversite development (OSD) masterplan has been developed for the CRL construction site at Mt Eden which is expected to be delivered by Eke Panuku after the works being undertaken by Link Alliance have been completed. The scope of the works being delivered by the Link Alliance, excludes the OSD area (shaded white in Figure 2.1).

The construction works required to reinstate the permanent aspects of the public space include paving, sealing, tie-in works, stormwater treatment, the installation of street furniture and landscaping. The works will be undertaken in a staged manner as the current construction works are progressively completed. Refer to the CEMP Addendum for a further detailed description of the works.

The PRR works are divided into ‘stages’ (based on activity for the Mt Eden Precinct, and locations for the NAL area) as illustrated in Table 2.1.

3. Key Personal

The key personal for the PRR works remain unchanged as the main works. Refer Section 3 of the CNV DWP.

4. Performance Standards

Section 4 of the CNV DWP provides the performance standards.

5. Receivers and Building Types

Section 5 of the CNV DWP provides the key receivers and their associated building types.

6. Risk Assessment – Noise

Section 6.1 of the CNV DWP includes the representative construction plant proposed for the PRR works. However, there are two plants that are not listed in Table 6-1 of the CNV DWP. A grader and asphalt paver has been identified as a potential equipment which is not captured in the CNV DWP These sources have a similar sound power level and noise character to a static/vibratory roller. Both a grader and paver will be used for road forming in the same locations as a drum roller. Therefore, the envelope of effects is unchanged and there is no substantive change required to the CNV DWP. As such, Table 6-1 can be used to predict activity noise levels. Potential noise effects from works are summarised in Section 12.1.

7. Risk Assessment – Vibration

Section 7.1 of the CNV DWP includes the representative vibration sources. There are no new or additional sources. Therefore, Table 7-1 can be used to predict vibration levels. Potential vibration effects from works are summarised in Section 12.2.

8. Blasting

Section 8 of the CNV DWP is not applicable to the PRR works.

9. Mitigation and Management

The mitigation and management measures outlined in Section 9 of the CNV DWP as well as the SSCNVMPs in Appendix C are appropriate and sufficient for the PRR works. No new mitigation or management measures will be needed to be identified.

However, one new SSCNMP may be required, in accordance with condition 37.2, for:

• 27 Boston Road – Pavement re-instatement works could be up to 75 - 80 dB LAeq for brief times. Therefore, if works are greater than two weeks than an SSCNMP may be required This has been prepared (reference C85) and is attached in Appendix A.

10. Communication

The same communication procedures as Section 10 of the CNV DWP will be carried out.

11. Monitoring

The same monitoring procedures as Section 11 of the CNV DWP will be carried out.

Appendix A: Site Specific Construction Noise Management Plan

C85 27 Boston Road (BRODIE European) SSCNMP

C85.1 Introduction

This Site Specific Construction Noise and Vibration Management Plan (SSCNVMP) is for 27 Boston Road (BRODIE European). A SSCNMP is required because construction is predicted to exceed the standards in CRL designation conditions 31.

This SSCNVMP has been prepared in accordance with CRL designation condition 37 and is Appendix C85 of the Mt Eden Main Works Construction Noise and Vibration Delivery Work Plan (CNV DWP). It is a supplementary document that builds on the CNV DWP, and therefore directly references relevant sections of the CNV DWP to avoid repetition. The objective of this SSCNVMP is to detail the best practicable option(s) (BPO) to avoid, remedy or mitigate the identified adverse effects from noise and vibration exceedances at 27 Boston Road.

This SSCNMP has been prepared for the Link Alliance and forms part of the Main Works Construction Environmental Management Plan (CEMP). This SSCNMP is triggered by the Mt Eden public realm reinstatement (PRR) works which are described in the Mt Eden Public Realm Reinstatement CEMP (the CEMP – PRR addendum). The CEMP – PRR addendum is appended to the Main Works CEMP.

C85.2 Engagement

Mt Eden Public Realm Reinstatement Works

Link Alliance representatives Lucy Waite and Micky Yang met with building representative Cameron Brodie on 10 November 2021. The matters discussed included:

• An overview of the project

• General programme, utilities relocation, tree pit excavation, and pavement reinstatement activities

• Overview of the CNV DWP and this SSCNMP, communications triggers, and monitoring

The single level industrial building is used as an automotive repairs workshop. It is not noise sensitive.

The relevant activities which are predicted to exceed the project standards are summarised below and will commence in early 2022. The CNV DWP sets out the BPO measures. Mitigation and management measures are included in Section 9 of the CNV DWP, and referenced in brackets, rather than repeated

• Pavement reinstatement – loudest being plate compactor, up to 75 – 80 dB LAeq for brief periods (noise barriers will be used – refer Section 9.5)

The estimated sound level difference across the façade with the windows and doors closed is 25 decibels. The predicted construction noise effects from Table 12.1 in Section 12.1 are predicted to result in reasonable noise effects Physical receiver mitigation, such as temporary relocation of affected receivers, alternative ventilation and façade sound insulation improvements, have been considered, but are not required as part of the BPO for the Mt Eden Station PRR Works.

Cameron Brodie agreed that prior communication of timeframes for works with the potential to exceed the relevant noise limits was an acceptable means of managing effects. No further activity specific consultation is necessary over and above regular communication (Section 10).

C62.3 Review Process

If affected site representatives request consultation in the future, this SSCNMP will be updated in accordance with CRL designation conditions 37.5, with consideration given to the following:

• The extent to which noise may exceed the designation standards

• The timing and duration of any exceedance

• The type of activity causing any exceedance

• A summary of the communication and consultation with the receiver

• The methods and measures to mitigate effects

• A statement of why they reflect best practicable option

Communications records are contained in the communication and consultation plan (CCP). This SSCNMP will be updated to summarise engagement and any agreed site-specific measures.
