INDICATIVE TIMELINE
March – April 2020
1. Site compound established. 2. Alternative car park created for 32 Normanby Road temporary use.
3. Sewer relocation south of rail – new sewer line
installed along eastern lane of Normanby Rd to connect to Mt Eden Prison.
4. Stormwater drainage – new drainage lines and inlet structures will be installed in low areas to help reduce the risk of flooding.
5. Retaining walls will be built to support the 32
Normanby carpark regrading, which is required as the new Normanby Rd bridge will be 2m higher than the current level crossing to allow clearance over the trains in the lowered trench.
6. 32 Normanby Rd carpark regrading. 7
INDICATIVE TIMELINE
Easter (April) 2020
7. Temporary utilities bridge foundations Foundations will be constructed for a temporary bridge required to get the utilities over the existing train tracks so the tracks can be lowered. 8. Sewer relocation The sewers from Water Street need to be diverted into the Normanby Rd sewer as the Water Street sewers currently cross south under the existing tracks and will be bisected by the lowered train tracks.
8
INDICATIVE TIMELINE
May – September 2020
9. Finish relocating sewer from Water Street 10. Complete temporary utilities bridge foundations 11. Reinstate carpark for 32 Normanby Road 12. Temporary utilities bridge construction – will arrive in pre-made sections & be assembled by crane.
13. Retaining wall construction – done to help create
work space and reduce traffic disruption during the temporary utilities relocation on Normanby Rd
14. Relocate utilities, including watermain, over temporary bridge.

The management plan process • Designation and resource consent
conditions require production of an Outline Plan and Delivery Works Plans describing the work to be undertaken and how it will be managed to mitigate potential adverse effects.
• An Outline Plan is being produced showing
the area of works, the utilities to be relocated, the scale of the work (including the temporary bridge across the rail corridor for pedestrians and utilities) and how the work will be undertaken.
Delivery Work Plans have been developed to manage impacts from construction such as: • • • • • • •
Air quality (dust) Noise and vibration Contaminated land Erosion and sediment control Social impact and business disruption Traffic access and parking Trees and vegetation
All form part of the Construction Environment Management Plan (CEMP)
10
The delivery work plans – who produces them and why? • The DWPs have been produced by our
specialists after assessing the nature of the works, their scope, scale and timing, the various designation and resource consent conditions, investigating likely effects and their extent.
• The specialists then provide guidance on
how to ensure compliance and mitigate impacts on people and the environment.
• The DWPs control how the work is undertaken, who shall undertake and be responsible for it and when the work can be undertaken in order to reduce potential impacts. Examples include, how soil is stored, how storm water is managed, how traffic and access can be maintained to businesses.
11
Talking to our specialists • Summaries of those draft plans were sent to all CLG members ahead of this meeting. The full plans are available to you on request.
• The specialists involved in drafting these
plans are here tonight to talk to the main points from their investigation and recommendations. You can provide your feedback directly and ask any questions you may have about their respective plans.
• The plans will shortly be finalised before undergoing an independent peer review and then lodgement with Auckland Council for final approval.

Construction Environmental Management Plan (CEMP) – Normanby Rd early works Purpose: To confirm the Normanby Road early works construction details and to set out how construction activities will be carried out and managed to avoid, remedy or mitigate adverse effects on the environment in accordance with the CRL designation and the Aotea to North Auckland Line (A2N) resource consent conditions. • All DWPs are sub plans to the CEMP • Sets out specific roles and responsibilities • Establishes processes, outlines training and induction, toolbox talks and pre-start meetings • Brief summary of each DWP • Monitoring and review process established
13
Air Quality The primary air discharge from this work is nuisance dust. Overall approach to managing nuisance dust is primarily based on removing spoil from site as soon as practicable, dampening exposed areas with water and ensuring that the site is kept tidy. Dust control methods include: • Controlling dust from excavation by placing material directly into trucks • Using water sprays to dampen dry or dusty material or surfaces • Minimising the volume and height of stockpiles • Placing limits on vehicle speeds • Ensuring sealed areas are cleaned regularly (washing or vacuuming sweeping) • Where necessary, sweeping public roads to remove any tracked dust • Delaying activities that have the potential to cause nuisance if strong winds are predicted
Visual monitoring will take place daily to gauge the effectiveness of the above dust management practices and enable immediate action to be taken if necessary. 14
Construction Noise and Vibration Objective: to identify the best practicable option (BPO) to avoid, remedy or mitigate adverse effects. The Delivery Work Plan is essentially a ‘goodneighbour’ code of practice: •
Staff training
•
Appropriate equipment selection
•
Use of safety alarms and noise barriers
•
Restrictions on night activities
•
Regular communication with stakeholders
•
Monitoring of noise and vibration focused on first occurrence of activity types and close proximity 15
Communication and Consultation A CCP has been prepared to ensure appropriate communication and consultation with affected stakeholders.
• The Mt Eden CLG will remain a key channel for communication with affected stakeholders and/or their representatives
• Communications will be shared via a range of
different channels that best meet stakeholder needs, including works notifications, regular newsletters, one-on-one discussions, community information sessions and CLG meetings
• Dedicated email and phone number for Mt Edenrelated queries
Engagement map for Normanby Rd early works
• Response timeframes and complaints process consistent with those outlined by CRL Ltd
16
Contaminated Land • All material excavated loaded directly into trucks and disposed of at licensed landfill. Material stockpiled during rainfall or overnight will be covered with an impermeable material and bunded to avoid stormwater run-off and dust.
• Dust and odour managed through Air Quality
Management Plan. i.e. damping down dry soil, using odour suppressant system if required, limited drop heights from excavators, covering stockpiles.
• Stormwater managed with by Erosion and
Sediment Control Plan with separation and diversion of clean stormwater away from areas of ground disturbance.
• All stormwater that encounters potentially
contaminated soil/fill treated as contaminated unless proved otherwise and captured and disposed of by a licensed liquid waste contractor.
• All imported material will consist of either clean
quarry materials and/or recycled crushed concrete aggregate.
• Monitoring will take place throughout the project to ensure contaminated soil/fill is managed in accordance with the DWP.
17
Social Impact and Business Disruption Key issues from community feedback
• Access for customers and deliveries
• Loss of street parking • Access to off-street car parking • Potential loss of trade • Noise and vibration impacts • Disruption to utility services
Mitigation Implementation of the suite of DWPs and Management Plans Ongoing communication Development Response Plan Crime Prevention through Environmental Design (CPTED) measures Ongoing monitoring
18
Traffic Management Overall approach Maintaining two traffic lanes on Normanby Road and two-way access to properties for pedestrians, cyclist and vehicles at all times. Temporary speed limit through works area will be 30km/h. Normanby Road
Private properties
• Kerbside parking of about 20-30 spaces on both sides
• Pedestrian, cyclist and vehicle access to all
of Normanby Road will be temporarily removed to accommodate both the on-street construction work zones while maintaining two traffic lanes.
• Manual STOP / GO management of Normanby Road rail crossing to ensure pedestrian and vehicle safety at the crossing during construction work.
• Potential traffic queues on Normanby Road, Boston Road and Nugent Street will be monitored by site traffic manager.
neighbouring properties will be maintained throughout the duration of the works.
• Manual STOP / GO control of vehicle
movements to properties where work zones overlap with vehicle crossing.
• Temporary parking created within 14-22
Boston Road to replace the staff & customer parking spaces affected by works inside 32 Normanby Road. 19
Impacted Vegetation • One notable Flame tree, on the corner of
Boston Road and Normanby Road, will be retained and protected during the works
• A mature English Oak tree at 14-22 Boston Road will be retained and protected
• Private trees and vegetation within 32 Normanby Road will be removed
• Weed species (Brush Wattle) and small
pioneer native species (Karamu) will be removed for parking within 14-22 Normanby Road.
Flame tree
Key mitigations:
• Trees replaced with 1:1 ratio • Trees offered to Mana Whenua & then the community for re-use
• Use semi-mature trees as part of replanting
& community will have the opportunity to be involvedEnglish in the replanting plan. Oak tree 20
