Executive Summary

The developments for the America’s Cup will require stormwater infrastructure and new services (water

supply, wastewater, power, lighting and communications).

The following Industrial and Trade Activities (ITA) and Hazardous Substances (HS) will also need to be

managed:

– ITA: boat repair at the syndicate bases.

– HS: limited quantities of Class 3 Flammable substances at the syndicate bases.

Stormwater Services

A number of site features and measures have been identified in relation to stormwater, potential ITA

discharge, and HS use associated with the proposed developments. These considerations and measures

are listed below:

Stormwater treatment devices designed to remove 75% of suspended sediment discharges, in

accordance with the Auckland Unitary Plan: Operative in Part (AUP:OP), will be provided.

Potential discharges from the sites will be managed through ITA Environmental and Hazardous

Substances Management Plans (ITA EHSMPs).

Potential ITA and HS Risks will be managed using the ITA Environmental and Hazardous Substances

Management Plans and Emergency Spill Response Plans (ESRPs).

There is no potential for flooding of, or damage or nuisance to, other properties.

The shoreline is protected by seawalls and the wharf discharges are at a distance from the shoreline

which minimises any potential for scour and erosion from the discharges.

Any potential adverse effects of stormwater and ITA discharge via stormwater in terms of land use,

discharge quantity and quality, and of HS use, storage and disposal are considered to be less than minor

based on the site features and provided the measures described above are implemented.

The proposed Wynyard Point works have minor beneficial effects compared to the existing, as there is a

reduction in potential for sediment discharge; due to the proposed modern stormwater treatment and car

park removal and a reduction in the storage of hazardous substances with the removal of the Stolthaven

South tank farm.

Other Services

Services (utilities) companies have been consulted and are supportive of the America’s Cup development.

Fire and Emergency New Zealand (FENZ) has had input to the proposed services for firefighting purposes.

Based on available information and discussions, the proposed connections for the syndicate bases have

adequate capacity to accommodate the anticipated demands outlined in this report. The proposed services

will be private lines owned, operated and maintained by Panuku Development Auckland (Panuku), as for the

existing Halsey Street Extension and Hobson Wharves.

For the proposed services, any adverse effects are considered to be less than minor on the basis that the

measures (including planning and coordination of works, temporary traffic management and methods such

combined trenches, directional drilling and routing of works) are undertaken.



3233847 // NZ1-15242902-18 0.18 // iii

The report identifies the potential for lighting effects from Business as Usual (BAU) and America’s Cup

Events for the Wynyard and Viaduct Harbour Precincts, caused by the potential for spill and glare from new

lighting, notably to sensitive sites such as apartments and hotels. A number of mitigation measures, including

use of zero tilt luminaries, and inclusion of event lighting procedures as part of an Event Management Plan,

are proposed. On the basis that these measures are incorporated into conditions of consent, and given the

existing environment against which the proposal must be assessed, the potential effects of lighting are less

than minor.

Introduction

1.1 Report Context

Panuku Development Auckland (Panuku), as Auckland Council's lead delivery agency, has been tasked with

providing waterfront infrastructure to host the America’s Cup Events and associated regattas in Auckland.

The Crown has agreed to provide significant funding to support the hosting of the Events in Auckland. The

Ministry of Business, Innovation and Employment (MBIE) is the Crown's lead business-facing agency,

responsible for New Zealand Major Events.

Beca Limited (Beca) has previously been commissioned by Panuku to prepare reports for the initial A36

Wynyard Basin application and corresponding Ferry and Fishing Industry Relocation Facility.

Beca has now been commissioned by Panuku and MBIE to undertake technical studies and engineering

concept drawings in relation to the new proposal, called "Wynyard Hobson".

Consents are sought for the use and development associated with holding the 36th America’s Cup in

December 2020 to May 2021 and any subsequent events within a 10 year period (each over a six-month

“event” period), and to construct, use and operate up to seven syndicate bases within the 10 year period.

The seven America’s Cup bases are proposed in and around Freeman’s Bay, which is located along part of

Auckland’s City Centre waterfront. This includes Wynyard Point, Hobson Wharf, a 74m extension to Hobson

Wharf, Halsey Wharf (comprising the Halsey Street Extension Wharf and Western Viaduct Wharf) and

Wynyard Wharf, including the surrounding land and waterspace.

Figure 2: Proposed infrastructure



3233847 // NZ1-15242902-18 0.18 // page 3

For the purpose of the RMA assessment, the effects have been assessed on the basis that the two bulk

liquid operators where Bases E, F and G are proposed have vacated the sites in advance of the event.

The proposal is made on the basis that part of Brigham Street will be permanently stopped. This will be

achieved through a separate process. For the purpose of the RMA assessment, the effects of the road

closure including works in the road have been assessed, but not the effects of the proposal on the road as it

currently exists. The proposal includes a new road connection north of syndicate Base C to maintain a

connection between Brigham Street and Hamer Street.

To support this resource consent application, Beca has prepared a suite of reports and drawings:

America’s Cup – Wynyard Hobson – Physical Infrastructure Technical Report

America’s Cup – Wynyard Hobson - Geotechnical Report.

America’s Cup – Wynyard Hobson - Groundwater Technical Report.

America’s Cup – Wynyard Hobson - Preliminary Site Investigations (Contamination) and Draft

Remediation Action Plan.

2 Existing Environment

2.1 Summary of Harbour Environment

The Waitematā Harbour environment is described in America’s Cup Ecological, Sediment and Water Quality

Technical Report (Golder Associates, 2018) with respect to water and sediment quality, and in America’s

Cup - Wynyard Hobson - Coastal Processes and Dredging Technical Report (i.e. tidal conditions, wave

climate and sedimentation with respect to coastal processes). This section provides a brief summary which

informs the assessment of stormwater effects.

The Waitematā Harbour is the receiving environment for stormwater discharges from the Auckland

waterfront and Central Business District (CBD). Water quality along the city waterfront reflects the overall

nature of the Waitematā Harbour catchment and the physical location of the site. Historical data indicates

that water quality is generally good with mean total suspended sediment levels less than 10g/m3. During

storm conditions, increases in the sediment concentration on the ebb tide can be expected. Water clarity in

the downtown area improves with distance from the shore and with depth and distance from the larger

Auckland Council stormwater discharges.

The downtown Auckland waterfront has been created over the past 140 years by reclamation, dredging and

construction, which have highly modified the environment. The surface of the seabed is marine mud with

some shelly sand, regularly mobilised by vessels using the berths. Sediment quality reflects the historical

uses of the downtown waterfront area and the material carried in stormwater from the CBD. Most of the

sediment carried by stormwater flows settles out of suspension in the waterfront basins. Indications from

waterfront sediment monitoring are that sediment quality has remained relatively consistent over time and

the sediment typically contains elevated trace elements, such as copper and zinc, and organic compounds.

The downtown waterfront is protected by hard seawalls which protect against erosion or scour as a result of

stormwater discharge.

2.2 Stormwater Management

2.2.1 Marine Works: Stormwater Drainage

Stormwater runoff from the 6.2ha of existing wharves between Wynyard Wharf and Princes Wharf is

discharged directly into the harbour. Wharves constructed in the last couple of decades are generally fitted

with formal stormwater drainage systems that collect runoff and direct it to discrete outlets whereas runoff

from older wharves typically discharges diffusely into the harbour.

An overview of the stormwater drainage regime on each of the wharves being used for the America’s Cup

event(s) is provided below.

2.2.1.1 Halsey Street Extension and Western Viaduct Wharves

The decks of the existing Halsey Street Extension and Western Viaduct Wharves are graded (approximate

cross fall of 0.75%) to direct stormwater via surface flow to deck grates and dropper pipes located at

intervals along both edges of the wharves. Stormwater is then carried by collector pipes prior to discharging

into the harbour. For the Halsey Street Extension Wharf, the collector pipes connect to nine underwharf

sumps, located across the wharf, which discharge into the harbour. The area of the wharf is

approx.18,000m2 and the roof area is approx. 4,500 m2.



3233847 // NZ1-15242902-18 0.18 // page 7

2.2.1.2 Hobson Wharf

Runoff from the paved surfaces on Hobson Wharf discharges diffusely into the harbour without any formal

collection system. Roof runoff from the Maritime Museum, which is located on Hobson Wharf, is collected in

roof gutters and then discharged directly to the harbour via downpipes and dropper pipes. The area of the

wharf is approx. 5,700 m2 and the roof area is approx. 3,500 m2.

2.2.1.3 Wynyard Wharf

There is no formal stormwater drainage system on Wynyard Wharf and runoff discharges diffusely from the

wharf, directly into the harbour. At the bulk liquids loading facility there is a bunded area which discharges to

an oil separator. The area of the wharf is approx. 9,500 m2.

A 2,750mm oval stormwater pipe (in situ concrete) discharges through North Wharf Wall, at the southern end

of Wynyard Wharf. This carries flows from the Freemans Bay catchment.

2.2.2 Wynyard Point Works: Stormwater Drainage

2.2.2.1 Wynyard Point

Bases C-G are on Wynyard Point, bounded by Hamer Street on the western side and by existing bulk liquid

storage facilities (tank farms) to the north and Silo Park to the south. To provide connectivity between the

syndicate base buildings and the water loadout area a section of Brigham Street will be stopped and

incorporated into the base areas.

The location of Bases C-G has been predominantly used for the storage of bulk liquids but some areas have

been cleared of storage tanks and are now used for the parking of cars and general storage. With the

existing Stolthaven South and Bulk Storage Terminals (BST) tanks due to be cleared in advance of the

tenants vacating, it is anticipated the site will be free of all tanks, foundations and associated pipework prior

to construction.

In total the site covers an area of approximately 2.4ha and is almost 100% paved. Stormwater runoff is

generally collected via a variety of private catch pits and drainage channels and directed to the public

stormwater drainage network prior to discharge directly into the harbour. The bunded areas within the

Stolthaven South and BST tank farms are understood to discharge via/to oil separators.

The existing (pre-development) stormwater flows for a 10 minute duration, 10% Annual Exceedance

Probability (AEP) storm event have been estimated using the Rational Formula as shown in Table 1.

Table 1: 10% AEP existing (pre-development) peak stormwater flows for proposed Wynyard Point site

Site Runoff Coefficient Rainfall intensity (mm/10 min)

Area (m2) Peak stormwater flow (m3/s)

Existing Site 0.95 15 24,000 0.57

2.2.2.2 Brigham and Hamer Street

There is a gravity stormwater network serving Brigham Street to the west of Wynyard Wharf. Stormwater is

collected in roadside kerb and channels. Catchpits at 50-180m centres feed into reticulation beneath the

road that discharges to the harbour via approximately seven outlet structures in the Brigham Street seawall.



3233847 // NZ1-15242902-18 0.18 // page 8

Hamer Street is served by a stormwater network similar to that described for Brigham Street. However, the

reticulation runs northward to a 600mm diameter outfall at the northern end of Wynyard Point.

2.3 Flooding and Overland Flow

2.3.1 Marine Works: Flooding and Overland Flowpaths

2.3.1.1 Halsey Street Extension, Western Viaduct and Hobson Wharves

As the existing wharves are located over water, at the seaward limit of the catchments, there are no flooding

and overland flow paths associated with them. Further, the Auckland Council GIS mapping does not identify

any overland flow paths or flood prone areas immediately landward of the existing wharves (i.e. no

immediate areas that might be affected by proposed additional wharf structures).

2.3.1.2 Wynyard Wharf

The Auckland Council GIS mapping shows three overland flow paths from west of Brigham Street

discharging across the road and into the harbour. The GIS map also incorrectly shows a flood prone area

between Brigham Street and Wynyard Wharf (see Figure 3). This is part of the Waitematā Harbour and is not

a flood prone basin.

2.3.2 Wynyard Point Works: Flooding and Overland Flowpaths

Figure 3: Overland flow path map, extracted from the Auckland Council GEOMAPS website



3233847 // NZ1-15242902-18 0.18 // page 9

2.3.2.1 Wynyard Point Landside Development Site

There are no flood prone areas or floodplains shown in the Auckland Council GIS map for the proposed

Wynyard Point site. Overland flow typically discharges via vehicular entrances into Hamer and Brigham

Street. This is reflected on the Auckland Council GIS map (Figure 3) which shows an overland flow path from

the ASB carpark into Brigham Street and from the BST site into both Hamer and Brigham Streets. The paved

sites adjoining the proposed syndicate bases (Stolthaven North tank farms and Wynyard Quarter) have

independent stormwater drainage which does not flow through the proposed site (outlined red).

2.3.2.2 Brigham and Hamer Streets

The Auckland Council GIS mapping shows three overland flow paths from west of Brigham Street

discharging across the road and into the harbour. The GIS map also shows an overland flowpath leading

from the BST tank farm into Hamer Street and a short section of overland flow on the western side of Hamer

Street between the entrances of the concrete batching plant and the adjacent Sanford yard.

2.4 Industrial Trade Activity (ITA) Management

2.4.1 Marine Works: Industrial and Trade Activities

2.4.1.1 Halsey Street Extension, Western Viaduct and Hobson Wharves: Industrial and Trade

Activities

The existing Halsey Street Extension, New Western Viaduct and Hobson Wharves are used for public

access, fishing vessel and general commercial wharfage. It is understood that they do not presently have

specific ITA management measures.

2.4.1.2 Wynyard Wharf: Industrial and Trade Activities

Present operations on Wynyard Wharf include:

Bulk liquids berths at the northern end of the wharf, associated with the BST and Stolthaven tank farms.

Layover use for a range of vessels (e.g. superyachts, bunker).

A seaplane berth and the Sealink vehicular ferry operation at the southern end of the wharf.

2.4.2 Wynyard Point Works: Industrial and Trade Activities

The existing ASB carpark and Panuku yard area are used for car parking and informal storage. It is

understood that they do not presently require specific ITA management measures.

The Stolthaven South and BST tank farm sites are currently used for bulk liquid storage operations. The bulk

liquid activities on the sites will be ceased and the site will be cleared of all operational tanks and pipelines

prior to occupation of the site for the construction of America’s Cup syndicate bases and infrastructure.

Management of the existing ITA activities are independent from the America’s Cup project and is therefore

not addressed here.

2.5 Existing Services

This section describes the existing land-based services. Drawings of the existing services are included in the

Existing Services Drawings 1 to 7. All services on the wharves are carried in ducts / flexible pipe suspended

on hangers beneath the wharves.



3233847 // NZ1-15242902-18 0.18 // page 10

2.5.1 Water Supply

2.5.1.1 Marine Works: Water Supply

Halsey Street Extension and Western Viaduct Wharves: 250mm dia and 150mm dia watermains are

located on the south and north sides, respectively, of Jellicoe St. Three (less than 10 year old) lines

extend onto the Halsey Street Extension Wharf. These include a 200mm dia watermain currently

supplying the Viaduct Events Centre, which is sprinklered.

Hobson Wharf: There is an existing private 100mm dia ring main on Hobson Wharf, serving the Maritime

Museum, which connects to a 150mm dia watermain at the landward end of Hobson Wharf, and then to

the public 250mm dia watermain in Quay St.

Wynyard Wharf: Two lines (250mm dia firefighting supply and “domestic” supply) cross Brigham St onto

Wynyard Wharf at the central bridging structure. There is an additional 100mm domestic supply line that

crosses Brigham St at the southern end of the wharf.

At the northern end of Wynyard Wharf there is a ‘foam’ pipeline which can be used by Fire and Emergency

New Zealand (FENZ) to suppress under-wharf fires.

2.5.1.2 Wynyard Point Works: Water Supply

Hamer Street: A 250mm dia water pipeline runs along the berm on the eastern side of Hamer Street. Two

existing 100mm dia lines lead off the main and into the Panuku yard and ASB carpark.

Brigham Street: A 250mm dia / 225mm dia water pipeline runs along the berm on the western side of

Brigham Street. Five existing 100mm dia lines lead off the main and into the proposed site at various

locations.

The berm on the western side of Brigham Street will be regraded to facilitate vehicle / vessel crossing

between Wynyard Wharf and the syndicate bases. The existing water infrastructure will need to be

modified/diverted to support this.

2.5.2 Wastewater

The existing wastewater reticulation proximate to the proposed development sites is laid out in the following

sections.

All the below wastewater lines ultimately connect to the new Wynyard Quarter pump station (corner of

Daldy/Pakenham Streets), which is presently under construction.

2.5.2.1 Marine Works: Wastewater

Hobson Wharf: A private rising main serving the Maritime Museum connects to the public system at a

manhole in Quay Street.

Halsey Street Extension and Western Viaduct Wharves: Two wastewater lines, 225mm dia and 250mm

dia, run northwards along Halsey Street to manholes at the corner where Jellicoe Street meets Halsey

Street. One line then continues northwards onto the wharf, serving the Viaduct Events Centre.

Wynyard Wharf: Wastewater connections lead from the Wynyard Wharf connecting to a 225mm dia

wastewater pipe on Brigham Street.

2.5.2.2 Wynyard Point Works: Wastewater

Hamer Street: Two 225mm dia wastewater pipes run along Hamer Street, one on each side. The pipe on

the eastern side of the road terminates at a manhole midway long the ASB carpark frontage. There is



3233847 // NZ1-15242902-18 0.18 // page 11

also a manhole adjacent to the boundary of the Stolthaven South and Panuku yard. The two wastewater

pipes appear to combine at a manhole adjacent to the south western corner of the BST site.

Brigham Street: A 225mm dia wastewater pipe runs along the western side of Brigham Street, serving the

adjacent buildings. It connects to a manhole at the southern end of Brigham Street midway along the BST

site frontage. There is an additional manhole at the southern end of Brigham Street connected to a

225mm dia wastewater pipe that was provided to support future development on Wynyard Point.

The berm on the western side of Brigham Street will be regraded to facilitate vehicle / vessel crossing

between Wynyard Wharf and the syndicate bases. The existing wastewater infrastructure will need to be

modified/diverted to support this.

2.5.3 Power

Existing power services are laid out in the following sections.

2.5.3.1 Marine Works: Power

Halsey Street Extension and Western Viaduct Wharves: There is an 11kV substation located at the

Viaduct Events Centre on Halsey Street Extension Wharf. This is connected by an 11kV line to a 22kV

substation at the Park Hyatt Hotel site, on the corner of Jellicoe and Halsey Streets. The 22kV substation

is currently being relocated further south along Halsey Street as part of the hotel construction.

Hobson Wharf: There is an 11kV substation on Hobson Wharf, which is understood to provide power to

the Maritime Museum.

Wynyard Wharf: There is an 11kV substation at the southern end of Wynyard Wharf which supplies the

existing ferry facilities.

2.5.3.2 Wynyard Point Works: Power

Hamer Street: There is an existing 11kV substation within the proposed site which is located on the

western side of the Panuku yard opposite the Firth concrete batching plant. There is another 11kV

substation on the western side of the road at 28 Hamer Street. Overhead 400V lines supply power to the

proposed site and other properties along Hamer Street.

Brigham Street: There is an 11kV substation at the southern end of Wynyard Wharf which supplies the

existing ferry facilities. A new 22kV substation is being installed on the south side of Jellicoe Street,

between Hamer and Brigham Streets. An overhead 400V power line on the western side of Brigham

Street supplies power to Bases C-G and other local properties.

There are a variety of existing private, above and below ground, electrical supply lines that serve the

existing facilities and lighting on Bases C-G.

To facilitate vehicular/vessel access from Brigham Street into the land site yards, it is anticipated that the

existing overhead line, and associated poles, located in the berm on the western side of Brigham Street will

need to be undergrounded in new ducting. Overhead lines in Hamer Street may also be undergrounded as

part of the street upgrade works and to support new vehicular crossings.

2.5.4 Communications

A number of existing telecommunication providers including Spark/Chorus Communications, Vector

Communications and Vodafone Communications, all provide services in Wynyard Quarter.

2.5.4.1 Marine Works: Communications



3233847 // NZ1-15242902-18 0.18 // page 12

Halsey Street Extension and Western Viaduct Wharves: Telecom ducts run along both sides of Halsey

Street and onto Halsey Street Extension Wharf, serving the Viaduct Events Centre. The ducting continues

to the end of the Western Viaduct Wharf.

Hobson Wharf: Multiple telecom ducts run along Quay Street and Hobson Street, passing onto Hobson

Wharf via under-wharf ducting to serve the Maritime Museum and the Outer Viaduct Harbour berths (the

telecom ducts extend to the end of the wharf).

Wynyard Wharf: Telecom ducting is bracketed to the western side of the wharf.

2.5.4.2 Wynyard Point Works: Communications

Hamer Street: Telecom ducting passes from Beaumont Street onto Hamer Street to serve the proposed

site and other local properties. Ducting runs along the west side of Hamer Street.

Brigham Street: Telecom ducts run along the berm on the western side of Brigham St, from Jellicoe St,

passing onto Wynyard Wharf at the curve in Brigham St adjacent to the ferry facilities.

It is anticipated that the berm on the western side of Brigham Street will need to be regraded to facilitate

vehicle / vessel crossing between Wynyard Wharf and the syndicate bases. Modifications or protection of

existing communication infrastructure may be required to support this.

2.5.5 Storage Tanks and Product Lines

There are a number of existing bulk liquid storage tanks located within the vicinity, both on the proposed site

and on adjacent land. There is also a variety of live and disused product pipelines leading to Wynyard Wharf

from adjacent tank farm sites.

Pipelines leading from the BST site, which is located to the south of the proposed development, cross

beneath Brigham Street onto a pipe bridge connected to Wynyard Wharf (i.e. over the harbour). The pipes

then run north beneath the wharf to the liquid bulk loading area. There are two over-road pipe bridges in the

area, one at the northern end of Brigham Street, and one at the northern end of Hamer Street.

Pipelines from the Stolthaven south site cross the road at 36 Brigham Street, then run along the seawall prior

to crossing onto Wynyard Wharf via an additional over-water pipe bridge. There is an additional over-road

pipe bridge leading from the Stolthaven North site, located to the north of the proposed development that

spans across Brigham Street and over the harbour onto Wynyard Wharf.

As noted in Section 2.4.2 the existing Stolthaven South and BST tanks, and associated pipelines, will be

removed by the leaseholder prior to construction.

Disused underground product lines are located throughout Wynyard Quarter, a legacy of the historic bulk

liquids use. Around Halsey and Jellicoe Streets, many of these have been removed during streetscape and

site development works since 2008. However the brownfields sites and road corridors on Wynyard Point are

still expected to contain a number of old lines.

3 Proposed Stormwater, ITA & HS Management

3.1 ITA Categories

As set out in the planning sections of the Assessment of Effects on the Environment (Unio Environmental,

2018), the activities at the America’s Cup bases are not listed precisely in Table E33.4.3 of the AUP:OP. It

might therefore be considered that they are not ITAs. However, out of an abundance of caution, the closest

categories from Table E33.4.3 have been identified and used as a basis for this assessment, together with

estimated activity areas. These are included in Table 2 below.

3.1.1 ITA Categories

3.2 Best Practicable Option

A Best Practicable Option (BPO) approach to integrated stormwater and ITA management is proposed for

the syndicate bases. This addresses the use of land for ITAs and the discharge of contaminants from ITAs.

Taking an integrated approach to stormwater management, the approach includes:

Design and construction of stormwater collection and treatment systems (see Section 3.3 and the

Proposed Services Drawings for further details).

Roofs will be required to use non high contaminant yielding coatings and will discharge via dropper or

underground pipes to the harbour without treatment, consistent with AUP:OP rules.

Implementation of emergency spill response procedures as per the ITA Spill Response Plan (see

Appendix A for draft table of contents, which provides a framework for this plan).

Maintenance of treatment devices in accordance with the manufacturer’s instructions, and device

monitoring for the first 2 years of operation to confirm (or refine) the maintenance regime.

The potable water used to wash down the AC36 race boats after racing (i.e. to rinse seawater off the race

boats) will discharge from the boat washdown area to the harbour. Requirements around tidiness of the

boat washdown area and washing with potable or rain water only are anticipated.

Implementation of the ITA EHSMP (see Appendix B for draft table of contents, which provides a

framework for this plan), which document the above measures.



3233847 // NZ1-15242902-18 0.18 // page 14

3.3 Stormwater Reticulation and Treatment

The proposed concepts for stormwater reticulation and treatment devices have been developed in

accordance with the following:

AUP: OP.

Auckland Regional Plan: Coastal.

Auckland Regional Council Technical Publication 108: Guidelines for Stormwater Runoff Modelling in the

Auckland Region.

Auckland Regional Council Technical Publication 10: Stormwater management devices design guideline

manual.

Auckland Code of Practice for Development and Subdivision, Chapter 4: Stormwater.

Stormwater reticulation and treatment arrangements for the America’s Cup infrastructure are shown in

Proposed Services Drawings 1 through 7.

Wharf decks and the syndicate bases on Wynyard Point will be graded for stormwater surface flow to surface

grates (catchpits for pavements) or slot drains. Stormwater will then be conveyed by pipework suspended

beneath the wharf decks or through new underground reticulation to proprietary treatment devices. The

existing stormwater grates and below wharf reticulation on Halsey Street Wharf will continue to be utilised

but will be modified to provide treatment to the Base A yard area through the provision of an additional

treatment chamber suspended beneath the wharf.

Treatment devices will comprise manholes fitted with proprietary treatment cartridges (e.g. StormFilter,

Jellyfish, or similar). The devices utilise rechargeable, self-cleaning, media-filled cartridges to absorb and

retain pollutants from stormwater runoff including total suspended solids (TSS), hydrocarbons, nutrients,

soluble heavy metals, etc. The devices will be sized to remove 75% of total suspended sediment for the

design water quality event.

The stormwater reticulation systems will be private owned, operated and maintained by the consent holder.

Regular monitoring of discharges from the treatment devices would be undertaken by the consent holder for

the first year of operation to confirm (or refine) the maintenance regime for the devices.

Operation and Maintenance Plans for the treatment devices, including as built drawings of the stormwater

system, will be provided to Council within 3 months of completion of construction.

Wharf and landside reticulation (primary system) will be sized for the 10% AEP rain storm event. Stormwater

flows generated by larger events will discharge to the harbour via overland / over wharf flow (secondary

system).

Gross pollutants, particularly during the event, will be addressed though source control measures including

yard sweeping, manual litter collection and potentially temporary installation of gross pollutant bags in

catchpits.

3.3.1 Marine Works: Stormwater

The stormwater runoff from the following areas on Hobson Wharf Extension and Halsey Street Extension

Wharf will be treated:

New wharf decks (including temporary building roof areas);

Existing wharf deck within the yard area footprint of Base A.

http://www.aucklanddesignmanual.co.nz/project-type/infrastructure/codes-of-practice/stormwatercodeofpractice



3233847 // NZ1-15242902-18 0.18 // page 15

Runoff from the new pedestrian-only breakwaters and the breakwater trunk on Halsey Street extension

wharf, which will only be subject to occasional low frequency vehicle traffic (vehicle turning), will not be

subject to treatment and will discharge directly into the harbour.

The treatment devices would be expected to be installed in offline mode and would be accessible from the

wharf deck for maintenance. The wharves will be divided into maximum 3,000m2 catchments to limit the size

of individual treatment devices suspended beneath the decks. Example calculations of the number of

cartridges needed for this catchment size and a typical drawing of a StormFilter manhole vault are included

in Appendix C. The calculations give a total of 6 cartridges per device for the catchment area based on:

Catchment area of 3,000m2.

The water quality rainfall intensity of 10mm/hr.

Run-off coefficient of 1.0.

A design water quality flow of approximately 9l/s.

The areas and approximate number of treatment devices for each of the new wharf sections are shown in

Table 3. Alternate equivalent devices might also be used, subject to Council acceptance.

Table 3: Wharf areas and treatment devices

New Wharf Approx. Area (m2) Approx. No. of Treatment Devices*

Hobson Wharf Extension (excludes

breakwater)

7,000 3

Halsey Street Base A Yard Area 2,000 1

* Based on each device containing up to 6 treatment cartridges.

Gross pollutants following events (involving high pedestrian numbers) will be managed through manual litter

collection and rubbish bin emptying and vacuum truck sweeping where required.

When wet weather occurs on Hobson extension gross pollutant transport via stormwater system will be

managed through the on-wharf treatment system. On Wynyard Point, gross pollutants will be collected

through in-catchpit gross pollutant filters.

3.3.2 Wynyard Point Works: Stormwater

Because of constrained landside area, drivers to separate stormwater from native ground and groundwater

to reduce potential for contamination of the stormwater, mean that proprietary treatment devices are the

most practicable solution for the proposed site.

In general, stormwater from Wynyard Point shall be treated and discharged into the ocean via new

underground reticulation and new outfalls. The stormwater system would be expected to include backflow

prevention (e.g. flap valve to protect the treatment device from seawater intrusion). Stormwater from roofs

and the new link roads, which are subject to low frequency vehicular traffic, will bypass the treatment devices

and will be conveyed directly into the harbour via underground reticulation.

A positive wharf deck surface gradient will convey the stormwater on the Wynyard Wharf infill structure to the

new landside network for treatment prior to discharge into the harbour.

The stormwater flow for a 10 minute duration, 10% Annual Exceedance Probability (AEP) storm event post-

development remain similar to those shown in 2.2.2 for Wynyard Point, except the rainfall intensity used to



3233847 // NZ1-15242902-18 0.18 // page 16

calculate the flow will increase to 17.5mm/10 min to account for the effects of climate change resulting in a

peak stormwater flow of 0.667m3/s. Wynyard Wharf extension/infill will also contribute an additional 0.11m3/s

to this peak stormwater flow, creating an overall combined peak flow of 0.777m3/s.

It is anticipated that three new stormwater outfalls will be required, each with a diameter of approximately

0.525m.

To limit the depth of stormwater reticulation pipes, it is assumed that the total combined catchment (of

approx. 12,600m2) will discharge via three separate outfalls each served by a separate treatment chamber.

Example calculations of the number of cartridges required for the individual catchments and a typical drawing

of a StormFilter manhole vault are included in Appendix C. The calculations give a total of 28 cartridges for

the catchment area based on:

Total catchment area of approximately 12,600m2 (see Table 4).

The water quality rainfall intensity of 10mm/hr.

Run-off coefficient of 1.0.

A total design water quality flow of approximately 37 l/s (split between three treatment devices).

An indicative stormwater treatment plan identifying the different areas is included as Figure 4.

Figure 4 - Stormwater treatment area plan

The areas and approximate number of cartridges for the Wynyard Point bases are shown in Table 4.

Alternate equivalent devices might also be used, subject to Council acceptance.

3.3.2.1 Link Roads/Buffer Zones

Due to the low frequency vehicular traffic expected to use the Northern Connector (with no car parking or

stopping), located along the northern boundary of the site, runoff from this area is expected to be at low risk

of containing contaminants and will therefore be conveyed by new underground reticulation and discharged

directly to the new outfalls.

3.4 Environmental and Hazardous Substances Management Plans and Spill Response Plans

Refer to Appendices A and B for draft tables of contents of the ITA EHSMPs and ESRPs. These include

expanded content and provide the framework for the plans for the America’s Cup bases.

The ITA EHSMPs and ESRPs for the syndicate bases will address both land use and potential for

contaminant discharge from the activities. They cover activities such as boat repair, waste management and

emergency spill response which will take place on the sites from mid/late-2019. ESRPs typically including

procedures such as spill kit contents, location and signage, isolation/containment of spills, notification (Fire

and Emergency New Zealand (FENZ) and Auckland Council if appropriate), clean up and disposal of spill

waste. The EHSMPs are expected to include management and operating procedures (e.g. secure access to

the bases, equipment (e.g. spill kits) and structural controls (e.g. bunding, covered storage) for activities such

as storage of HS, painting, waste management etc. Refuelling will not be undertaken on the bases, instead

the existing facility at Westhaven Marina will be used by the syndicates.

Each syndicate will be responsible for preparing and implementing the EHSMP and ESRP covering its

activities, with Panuku overviewing the process. As the syndicates are yet to be confirmed (other than the

host and challenger of record) it has not been possible for full EHSMPs and ESRPs to be prepared for this

report. However, expanded draft tables of contents for the ITA EHSMPs and ESRPs for the America’s Cup

bases are included in Appendices A and B. The EHSMPs and ESRPs are living documents, which will be

reviewed and updated regularly (e.g. 2 yearly) to cover any change in activities and/or potential ITA

discharges.

At this stage it is assumed that once the temporary bases have been removed the wharves will become (or

return to) public access areas. Similarly, once the temporary bases have been removed from the Wynyard

Point Landside Facility the land is likely to be allocated for residential or recreational land uses. As such,

ITAs will no longer take place on Halsey Street Extension Wharf, Hobson Wharf Extension, Wynyard Wharf

or Wynyard Point. The EHSMP and ESRP will therefore no longer apply to these temporary base areas.

However, should one of the areas be allocated as a permanent base for ETNZ the EHSMP and ESRP may

still apply.



3233847 // NZ1-15242902-18 0.18 // page 18

3.5 Hazardous Substances

ETNZ has advised that the following approximate quantities and types of HS will be stored on each syndicate

base, to be used for boat repairs:

Acetone (250 litres)

Paint (nominal 100 litres)

Epoxy (nominal 100 litres)

Thinners (nominal 20 litres).

These are Class 3 Flammable Liquids.

The HS will be stored in either a Dangerous Goods (DG) store that complies with NZ regulations or 1-2

proprietary NZ-compliant DG cabinets. The store/cabinets have built in bunds and will be contained in

roofed, well ventilated areas of the syndicate buildings. They will be surrounded by an exclusion and safe

working zone where ignition sources, smoking etc. will not be permitted. Signage will be required at the store

and entrance to the area. Two fire extinguishers will be required.

There will be no outlet to stormwater or trade waste from the DG store. 250l spill kits appropriate for

flammable substances will be kept on site. Any spills will be managed as per the syndicate base ESRPs, as

indicated above. Hazardous Substance Location certification (from a compliance certifier) is required for the

site/s if the actual stored quantities are above 100L of class 3.1B (Acetone), as indicated above. A training

plan covering management practices and emergency spill response procedures will be prepared and

implemented for syndicate personnel working on the base. The measures above will be documented by each

syndicate in the EHSMPs.

Separately, the Construction EHSMP will include a management plan if any HS are to be used on site during

construction (refer to the America’s Cup – Wynyard Hobson - Base Infrastructure Technical Report).



3233847 // NZ1-15242902-18 0.18 // page 19

4 Proposed Services

The proposed syndicate bases will be supplied with lighting, power, water, wastewater and telecom (fibre

optic) services. An overview of the approximate demand and infrastructure required is provided in this

section.

As a general approach, the marine works services will be connected to the existing landside reticulation

independent of existing wharf-based services to avoid interference with existing facilities (e.g. Maritime

Museum). Services provided will be suspended beneath the new and existing wharf decks. Construction of

initial below-ground ducting and pipelines will be required to extend the existing land-based services. It is

however anticipated that Base A will primarily utilise existing services that serve the VEC. The proposed

services will be private lines owned, operated and maintained by the consent holder.

The majority of services on Wynyard Point will be connected to existing services networks in Hamer and

Brigham Streets. As for the marine works services, the new services will be private lines owned, operated

and maintained by the consent holder.

Concept drawings showing the layout of proposed services are presented in the Marine and Wynyard Point

Works Proposed Services Drawings. The layouts and connection points shown are indicative only, subject to

detailed design and agreement with the relevant services organisations.

4.1 Water Supply

4.1.1 Water Supply General

Water supply will be provided to all syndicate bases for potable and boat washdown water and firefighting.

The supply will terminate at the boundary of each base with a valve and meter.

Concept calculations have been carried out to give indicative and approximate order of magnitude of water

demand quantities, with the results as follows:

Potable water for syndicate bases 6,250 Litres per day per base (based on 100 personnel/base)

Potable water for superyachts 30,000 Litres per day (based on 30 superyachts with an average

vessel length of 50m, and crew of 10 as per PIANC, 20131)

Water for washdown of race boats 50,000 Litres per day

FENZ has recommended that the syndicate buildings be sprinklered because of the nature of carbon fibre

fires (the race boats largely consist of carbon fibre). The sprinkler systems will be connected to the local

water supply (refer below). Water supply for active firefighting on the wharves using FENZ appliances is

expected to be sourced predominantly from the potable water system (approximately 25 litres per second

demand). Due to the presence of potentially significant amounts of carbon fibre, it is anticipated that the

sprinkler system shall have a water demand in the order of 80 litres per second, providing carbon fibre etc.

shall not be stored to heights greater than 1.2m. If the storage height exceeds 1.2m, a more significant water

demand for the sprinkler system is required.

Association of Navigation Congresses (PIANC)



3233847 // NZ1-15242902-18 0.18 // page 20

Appendix D includes further detail regarding firefighting provisions and includes minutes of the meeting with

FENZ to discuss the proposed development.

4.1.2 Marine Works: Water Supply

On Halsey Street Extension Wharf, the existing watermain is anticipated to supply the sprinkler system and

hydrants on the wharf. A single watermain will supply the Hobson Wharf extension (hydrants and sprinkler

system), which accommodates a single base only. The water supply line on Wynyard Wharf is expected to

connect to the public watermain in Brigham Street and will feed sprinkler systems and wharf hydrants.

Permanent dry standpipes utilising water intake directly from the ocean may also be utilised subject to FENZ

approval.

It is expected that connection points for the water supply to the wharves will be as follows:

Halsey Street Extension Wharf: existing hydrants to be utilised or connection to the existing 200mm dia

watermain which currently provides for the VEC.

Hobson Wharf: connection to either the existing underwharf 125mm dia watermain beneath the Harbour

Entrance Protection Wharf, or the 150mm dia or 250mm dia public watermains on Quay Street if

connection to the underwharf watermain is not feasible.

Wynyard Wharf: connection to either the 225mm dia watermain at the south end of Brigham Street,

and/or the 250mm dia watermain north of the bases on Wynyard Wharf.

4.1.3 Wynyard Point Works: Water Supply

A single watermain will supply each of the bases (hydrants and sprinkler system).

The existing 225mm dia water main in Brigham Street will be diverted, along the base frontage, to facilitate

the berm regrading and to accommodate the base foundations. New underground reticulation pipelines will

connect into the diverted water main to provide water supply to the Wynyard Point bases. Flow capacity and

pressure testing of the watermain will be undertaken as part of the project detailed design.

4.2 Wastewater

4.2.1 Wastewater General

Wastewater connections are to be provided to all syndicate bases for drainage from sanitary facilities and

boatshed floors.

Concept calculations have been carried out to give indicative and approximate order of magnitude

wastewater generation quantities, with the results as follows:

Wastewater generated by syndicate bases 6,250 Litres per day per base (based on 100

personnel/base)

Wastewater generated by superyachts 75,000 Litres per day (based on 30 superyachts with an

average vessel length of 50m, and crew of 10 as per

PIANC, 2013)

4.2.2 Marine Works: Wastewater

A pumpout facility will also be provided for superyachts berthed on Halsey Street Extension Wharf (west),

similar to the vacuum pump out system installed in the Outer Viaduct Harbour for the 2000 America’s Cup.

Connection points for these lines are expected to be:



3233847 // NZ1-15242902-18 0.18 // page 21

Halsey Street Extension Wharf: existing wastewater system serving the VEC to be utilised.

Hobson Wharf: the existing manhole on the north side of Quay St.

Wynyard Wharf: the existing manhole at the south end of Brigham Street / north end of Daldy Street,

adjacent to the existing ferry facilities.

4.2.3 Wynyard Point Works: Wastewater

The existing 225mm dia waste water line in Brigham Street will be diverted, along the base frontage, to

facilitate the berm regrading and to accommodate the base foundations. This will require the construction of

several new manholes. Gravity lines from each base will be connected directly to the diverted line or new

manholes. Preliminary assessment indicates that this pipeline has sufficient capacity but a detailed flow

capacity assessment will be undertaken during detailed design. If there is insufficient capacity, then on-site

storage will be provided.

4.3 Power

4.3.1 Power General

It is understood that at previous events, mobile generators significantly supplemented electrical provision to

the bases to avoid over-utilising the existing land-based infrastructure and safeguard the syndicates from any

power outages. It is anticipated that a similar approach may be taken for the syndicate bases in event mode.

4.3.2 Marine Works: Power

During non-event operation (Business-as-Usual, BAU) power will be provided to each syndicate base, via

individual power pedestals, and also to the new lighting infrastructure. Cables will be protected by ducts

suspended beneath the wharf decks.

Anticipated connection points for the new facilities are:

Halsey Street Extension Wharf: the base buildings and yard areas will be serviced by the existing network

serving the VEC surrounding wharf areas. Connections to the existing 22kV substation, which is currently

being relocated south along Halsey Street from the Park Hyatt Hotel site will be provided to accommodate

superyacht vessel berthing along the western side of the wharf.

Hobson Wharf: the existing 11kV substation on Hobson Wharf;

Wynyard Wharf: the 22kV substation which is being installed on the south side of Jellicoe St, between

Hamer and Brigham Streets.

4.3.3 Wynyard Point Works: Power

New underground ducting will be provided to accommodate power cables and facilitate connection to the

existing network.

Anticipated connection points for the new facilities are:

The existing 11kV substation which is located within the proposed site, on the western side between

Bases E and D.

The 22kV substation which is being installed on the south side of Jellicoe St, between Hamer and

Brigham Streets.



3233847 // NZ1-15242902-18 0.18 // page 22

As noted in section 2.5.3.2, to facilitate vehicular/vessel access from Brigham Street into the land site yards,

it is anticipated that the existing overhead line, and associated poles, located in the berm on the western side

of Brigham Street will need to be undergrounded in new ducting.

It is currently assumed that the existing substation C-236, adjacent to the SeaLink ferry terminal, will remain

in place. However, should the substation be decommissioned and removed as a result of the commissioning

of the new 22kVa substation on Jellicoe Street, the yard boundary for Base G can be amended to become

the full width of the building, as shown in the Wynyard Point Works Civil Drawings.

4.4 Lighting

4.4.1 BAU Lighting

Lighting poles with streetlight luminaires (zero tilt), at a height of approximately 8m will be situated along the

Hobson Wharf Extension at a spacing to provide a safe illumination level, similar to the existing lighting on

Halsey Street Extension, Western Viaduct and Hobson Wharves. Zero tilt luminaires are oriented parallel to

the ground, with all light projected below the horizontal plane.

The approach to provision of lighting to the Syndicate Bases will be similar to the above, and similar to the

existing lighting in the ASB carpark. Consideration of mounting zero tilt lights on the Base buildings would be

of benefit. Existing street lights and poles on Hamer and Brigham Streets will be removed as required to

facilitate construction, and replaced.

The new lighting will be designed in accordance with Crime Prevention Through Environmental Design

(CPTED) principles and consistent with E24.6.1 General Standards in the AUP:OP – Rules as applicable

(Lighting Category 2 Low brightness for the Coastal Marine Zone). Power will be supplied by underwharf

cables and underground ducting as noted above.

Navigational lighting is addressed in America’s Cup Wynyard Hobson Navigational Safety and Utility

(Navigatus, 2018).

4.4.2 Construction Lighting

Construction lighting is covered in the America's Cup Wynyard Hobson Base Infrastructure Technical Report

(Beca, 2018).

4.4.3 Event Lighting

The event details are yet to be fully developed at this stage of the project. However it is assumed that the

America’s Cup event lighting will be similar in principle to that of the 2018 Volvo Ocean Stop Over, except

that unlike the Volvo event the America’s Cup operation will, in the main, be during daylight hours. It is

expected that America’s Cup entertainment events will take place during the hours of 7am - 10pm (pre-

curfew hours). Anticipated lighting arrangements are as follows:

Bases: It is assumed that event lighting will be as per BAU lighting because the main activity will be

during daylight hours and assuming any night activity will be inside the syndicate base buildings fitted with

blackout drapes (or with no/limited windows).

Primary entertainment areas (Eastern Viaduct, Te Wero Island, North Wharf, Jellicoe St carpark and Silo

Park): the existing lighting will be used but this may not cover the full extent of these areas sufficiently for

event activities, in terms of safety and security. Temporary lighting will therefore be installed in addition to

the existing lighting when event activities are taking place. The additional temporary pole-mounted



3233847 // NZ1-15242902-18 0.18 // page 23

luminaires will be mounted at heights between a minimum of 6m and a maximum of 10m. The actual

height will be determined during the design phase to ensure minimum number of poles for the coverage

areas. Zero tilt luminaires will be used.

Temporary feature lighting, big screens, and lighting for hospitality features are also expected to be

located in the primary entertainment areas, similar to the Volvo event. The temporary feature lighting (i.e.

all light may not necessarily be projected below the horizontal plane) is expected to be used at specific,

limited times during the event and also to have controlled beams, limiting light to the particular illuminated

feature/effect.

Television broadcast lighting may be used in outdoor public places from time to time during the event,

although the daytime nature of the racing means this will be limited.

The event lighting will be covered in a Lighting Management Plan as part of the Event Management Plan,

and will address the following:

Map of surrounding light sensitive areas.

All event lighting to comply with AUP:OP requirements for pre-curfew and curfew levels for spill light and

glare and general lighting planning rules. Spill light and glare standards to windows of habitable rooms of

lawfully established dwellings to be complied with.

Confirmation design is in accordance with CPTED principles and consistent with E24.6.1 General

Standards in the AUP:OP – Rules as applicable.

Layout and luminaire type of temporary lighting.

Location and orientation of big screens, feature lighting and lighting for hospitality features.

Outside broadcast area locations.

10pm shut down time for temporary additional event lighting.

4.5 Communications

Similarly to power supply, telecom and fibre optic connections will be provided to each syndicate base by

means of individual telecom pedestals. The expected connection points to the existing communications

system are:

Halsey Street Extension and Western Viaduct Wharves: utilisation of the existing communication network

serving the VEC or connection to the communications chamber at the landward end of Halsey Street

Extension Wharf for additional supply to support the superyacht berths.

Hobson Wharf: connection to the communications chamber at the landward end of Hobson Wharf.

Brigham Street and Wynyard Wharf: connection at the communications chamber towards the southern

end of Brigham Street.

Jellicoe and Hamer Street Intersection: connection to the existing communications chamber.

4.6 Storage Tanks and Product Lines

As part of the land transfer, Stolthaven and BST will be required to remove all of their assets including tanks,

foundations and product pipes located on, or leading from, the Stolthaven South and BST sites. This will

include the removal of the pipelines and associated pipe bridges leading to Wynyard Wharf.



3233847 // NZ1-15242902-18 0.18 // page 24

5 Assessment of Effects on the Environment

5.1 Stormwater (and ITA)

5.1.1 Marine Works

No additional stormwater will be discharged into the harbour as a result of the proposed wharf structures.

Rainwater and atmospheric particulates will be deposited in the harbour regardless of their presence.

Vehicle traffic on the wharves will be limited during both the America’s Cup period and once the wharves

return to public use, hence only low levels of particulates (e.g. tyre particles) and hydrocarbons from

vehicles. The hard concrete surface of the wharves will also produce little sediment. There is therefore

minimal potential to generate discharge of suspended sediment in stormwater runoff from the proposed

wharves.

Activities with the potential to result in discharges via stormwater runoff will be managed by procedures set

out in the ITA EHSMP. For example, race boat maintenance will typically be undertaken under cover within

the syndicate buildings, minimising the potential for material to be mobilised in stormwater runoff. General

housekeeping matters such as site tidiness and waste management will be addressed by procedures in the

EHSMP. Boat washdown water, as described in Section 3.2, will be required to contain only potable (or rain)

water and harbour water from the boats. The quantity of boat washdown water (50m3/day on racing and

training days) is negligible (0.01%) compared with the volume of seawater exchanged in the water body on

each tide.

Modest quantities of HS used for boat maintenance (of the order of 100 – 250 litres per substance) will be

stored at the syndicate bases. This will be confined to the ETNZ base once the temporary bases are

removed. The ESRPs and the EHSMPs (refer to Appendices C and D) will set out storage requirements for

these substances e.g. DG store or cabinets, covered and self-bunded; labelled containers; handling/use

procedures, and actions to mitigate any discharge in the event of a spill. Management measures will also

include an exclusion/safe working zone around the DG store, where ignition sources will not be permitted.

In addition to the above, stormwater from the proposed wharf structures and Base A will be collected and

treated prior to discharge. The stormwater treatment devices will be designed to remove 75% of total

suspended sediment, in accordance with the AUP:OP. The treated stormwater will then be substantially

diluted by the daily tidal flows within the wider harbour. This is illustrated by comparison of the total

stormwater discharge from the proposed wharf extension for the 1% AEP 24 hour rainfall event (2,000m3)

with the daily volume of water exchanged in the Waitematā Harbour (160 million m3).

There will be negligible scour and erosion effects from the discharge, as the discharge points on the wharves

are in water depths of at least 3m and are seaward of the shoreline, which is also protected by hard seawall

structures.

There is no potential for flooding of, or damage or nuisance to, other properties because the sites are located

over the Waitematā Harbour (i.e. seaward of the downstream end of the Freemans Bay catchment) and do

not obstruct any existing overland flowpaths or floodplains. As noted in Section 3, the area between Brigham

Street and Wynyard Wharf is harbour waters and not a floodprone area, and is therefore not affected by the

development.

5.1.2 Wynyard Point Works

There will be no increase in impervious area as a result of the Wynyard Point works and there will be no

additional stormwater discharged into the public stormwater network or harbour.

Vehicle traffic on the site is anticipated to reduce as a result of the development as the ASB carpark (approx.

250 spaces) will be replaced by yards with limited vehicular traffic, hence a reduction on levels of particulates

(e.g. tyre particles) and hydrocarbons from vehicles. The hard paved surface of the yards and buildings will

also produce little sediment.

Activities with the potential to result in discharges via stormwater runoff will also be managed by procedures

set out in the ITA EHSMP. With the removal of the Stolthaven South and BST tank farms the quantity of HS

stored on the site will also be significantly reduced. Other HS associated with the syndicate bases will be

managed in the same way as for maritime works.

In addition to the above, stormwater from the proposed Wynyard Point yards will be collected and treated

prior to discharge. Therefore, the discharge of sediment from Wynyard Point into the harbour will be reduced

compared with the existing situation.

The potential for flooding of, or damage or nuisance to, other properties will also be reduced as a result of

the development because:

Actual flows remain small and the new stormwater drainage system will capture surface flow;

The sites are at the downstream end of the catchment;

Flows from the primary stormwater system will discharge directly into the harbour via underground

reticulation;

The Wynyard Point pavement will be graded so that flows in excess of the primary system capacity will

flow overland, into Hamer or Brigham Streets prior to discharging directly into the harbour;

There are no affected flood prone areas or floodplains; and

At low points (eastern edge of Brigham Street) overflow points will be provided directly to the harbour.

5.1.3 General

Any adverse effects of stormwater and ITA discharge via stormwater in terms of land use, discharge quantity

and quality, and of HS use, storage and disposal are considered to be less than minor based on the site

features and provided the measures described above are implemented.

The proposed Wynyard Point development has minor beneficial effects compared with the existing situation,

as there is a reduction in potential for sediment discharge, due to the proposed modern stormwater treatment

and car park removal and a reduction in the storage of HS with the removal of the Stolthaven South tank

farm and the BST tank farm.

It is also notable that these activities have taken place in the same general area during the 2000 and 2003

America’s Cup events, as well as the more recent events overseas. The procedures outlined in these

documents have incorporated the results of discussions with ETNZ, demonstrating a level of experience with

HS management practices within the syndicates.

5.2 Effects of Services (excluding Lighting)

The proposed connections and anticipated demands for the America’s Cup event infrastructure have been

discussed with the relevant services companies and stakeholders, as follows:

Water supply and wastewater: Watercare.



3233847 // NZ1-15242902-18 0.18 // page 26

Power: Vector.

Communications: Chorus.

Firefighting: FENZ.

The services (utilities) companies are supportive of the America’s Cup event(s) and have indicated that in

principle there should be sufficient capacity (refer to correspondence in Appendix D). FENZ has had input to

the proposed services for firefighting purposes. The diversion of existing services will be undertaken in

discussion with the relevant service company to ensure disruption is minimised. The proposed connections

should have adequate capacity to accommodate the anticipated demands outlined in this report.

5.2.1 Marine Works

Connections to existing services for Halsey Wharf Extension and Wynyard Wharf (south) are likely to require

pipework to run across sections of Jellicoe St and Karanga Plaza that was upgraded some 7-15 years ago.

Construction of these connections has the potential to disrupt activities in these areas and affect the surface

finish. The potential disruption will be reduced by adopting measures such as combined services trenches (to

reduce the number of trenching operations), routing works as far as possible through existing access

roadways or other less sensitive/lower quality surface finishes rather than high quality finish public areas (to

reduce impacts on public access and existing landscaping finishes), directional drilling (where ground

conditions support this), temporary traffic management where connections cross live roads (refer to the

America’s Cup – Wynyard Hobson - Traffic and Transport Technical Report), and planning and coordinating

the works with adjacent businesses and with construction access requirements.

Any adverse effects of the proposed services are considered to be less than minor on the basis that the

measures described above are undertaken, particularly including planning and coordination of works,

temporary traffic management and methods such as combined trenches, directional drilling and routing of

works.

5.2.2 Wynyard Point Works

Brigham and Hamer Streets are in brownfields condition and serve the existing commercial developments,

bulk liquids storage sites, and ASB carpark. Planning and coordinating the works with the site operators and

with construction access requirements, standard trenching practices, and temporary traffic management will

be utilised to reduce impacts of the connection work on adjacent businesses and road users.

Any adverse effects of the proposed services are considered to be less than minor on the basis that the

measures described above are undertaken, particularly including planning and coordination of works,

temporary traffic management and methods such as combined trenches, directional drilling and routing of

works.

5.3 Lighting Effects

5.3.1.1 BAU Lighting

Sites potentially sensitive to lighting (e.g. apartments, hotels) are grouped to the east and south of Viaduct

Harbour, Pakenham Street, and 1.5km north on Stanley Point. The northern extent of Wynyard Point (i.e. the

bulk liquids storage and existing carpark area) are not sensitive sites. Other potential receptors are marine

users and motorists. In terms of the general context of the development, the majority of the site falls under

Lighting Category 2 Low Brightness in the AUP:OP. However, the landside setting (i.e. the waterfront from

Wynyard Point through North Wharf promenade and Viaduct Harbour to Quay Street) is categorised in the

Plan as Lighting Category 3/4 Brightness.



3233847 // NZ1-15242902-18 0.18 // page 27

The zero tilt luminaires used for BAU lighting will limit any spill and glare from the proposed operational

lighting. The lighting will be designed in accordance with AUP:OP requirements for the nearest potentially

sensitive site at the northern end of Princes Wharf, during construction of the breakwater. It will be difficult to

perceive a difference compared with existing lighting from the south side of Viaduct Harbour, the harbour

channel and the physically remote Stanley Point, noting the general level of waterfront lighting from Wynyard

Point through North Wharf promenade, Te Wero and Quay Street towards Queens Wharf (AUP:OP Lighting

Category 3/4 Brightness).

Effects on motorists are reduced by the zero tilt luminaires and because the proposed lighting is shielded by

existing development and the proposed syndicate buildings. No lighting will be directed to the night sky.

5.3.1.2 Event Lighting

The surrounding environment and potentially sensitive sites as regards event lighting are as noted in the

preceding section. A number of measures have been identified to reduce any adverse effects of event

lighting. An Event Management Plan will include lighting measures together with relevant contextual

information as per the above.

Implementation of these measures for events is considered to manage appropriately any adverse effects of

event lighting.

It is also noted that the America’s Cup event(s) on any individual evening would see less activity than the

level of night time activity associated with the Volvo Ocean Race (which was assessed as having negligible

adverse lighting effects). The America’s Cup event is focussed around daytime racing and temporary

additional lighting will be shut off at 10pm (curfew).

5.3.1.3 Overall Lighting Effects

The potential for lighting effects from BAU and America’s Cup event lighting, caused by the potential for spill

and glare from new lighting, has been identified. A number of mitigation measures, such as use of zero tilt

luminaries, and inclusion of event lighting procedures in the Event Management Plan, are proposed. On the

basis that these measures are incorporated into conditions of consent, and given the existing environment

against which the proposal must be assessed, the potential effects of lighting can be appropriately managed

and are considered to be no more than minor.



3233847 // NZ1-15242902-18 0.18 // page 28

6 Mitigation, Monitoring and Draft Conditions of Consent

The proposed mitigation and monitoring described in this assessment is summarised below:

Preparation and implementation of ITA ESRPs and EHSMPs (refer to Appendices A and B, which

provide the framework for these plans) for the syndicate bases.

Stormwater treatment devices designed to remove 75% of suspended sediment discharges for the

permanent wharf extensions, Base A yard area, wharf infill and Wynyard Point yard areas.

Roofs on buildings to use non high contaminant yielding coatings and will discharge via dropper or

underground pipe directly to the ocean, consistent with AUP:OP rules.

Maintenance of treatment devices in accordance with the manufacturer’s instructions.

Monitoring of discharges from the treatment devices for the first year of operation to confirm (or refine) the

maintenance regime.

Storage of HS in self-bunded DG stores or cabinets surrounded by an exclusion/safe working zone.

Potential disruption from constructing connections to existing services to be mitigated e.g. by combined

services trenches, routing works as far as possible through access corridors rather than flagstoned public

areas, directional drilling where ground conditions support this, temporary traffic management, planning

and coordinating the works with adjacent businesses and construction access needs.

Planning and coordinating connection works with adjacent businesses and construction access needs,

standard trenching practices, and temporary traffic management will be used to mitigate potential

disruption by services connection activities on Hamer and Brigham Streets.

Design drawings and specifications to be provided to Auckland Council prior to the start of construction

for information.

Inclusion of event lighting in the Event Management Plan as follows:

– Map of surrounding light sensitive areas.

– All event lighting to comply with AUP:OP requirements for pre-curfew and curfew levels for spill light

and glare and general lighting planning rules. Spill light and glare standards to windows of habitable

rooms of lawfully established dwellings to be complied with.

– Design to be in accordance with CPTED principles and consistent with E24.6.1 General Standards in

the AUP:OP – Rules as applicable.

– Layout and luminaire type of temporary lighting.

– Location and orientation of big screens, feature lighting and lighting for hospitality features.

– Outside broadcast area location.

– 10pm shut down time for temporary additional event lighting.

The above measures could form the basis for conditions of consent.

7 Summary and Conclusions

7.1 General

The proposed America’s Cup development will require stormwater infrastructure and new services (water

supply, wastewater, power, lighting and communications). The following ITA and HS will also need to be

managed:

– ITA: boat repair at the syndicate bases.

– HS: limited quantities of Class 3 Flammable substances at the syndicate bases.

Services (utilities) companies are supportive of the America’s Cup development and have indicated that in

principle there should be capacity within the wider Wynyard Quarter service networks. FENZ has had input to

the proposed services for firefighting purposes. Based on available information and discussions, the

proposed connections for new works have adequate capacity to accommodate the anticipated demands

outlined in this report. The proposed services will be private lines owned, operated and maintained by

Panuku, as for the existing Halsey Street Extension and Hobson Wharves.

A number of site features and measures have been identified in relation to stormwater, potential ITA

discharge, and HS use associated with the proposed developments. These considerations and measures

are listed below:

Stormwater treatment devices designed to remove 75% of suspended sediment discharges, in

accordance with the AUP:OP, will be provided.

Potential discharges from the sites will be managed through ITA EHSMPs.

Potential ITA and HS Risks will be managed using the ITA EHSMPs and ESRPs.

There is limited potential for flooding of, or damage or nuisance to, other properties.

The shoreline is protected by seawalls and the discharges are either at a distance from the shoreline

(discharges from wharves) and/or from existing outfalls which minimises any potential for scour and

erosion.

7.2 Effects of Marine Works

Any potential adverse effects of stormwater and ITA discharge via stormwater in terms of land use,

discharge quantity and quality, and of HS use, storage and disposal are considered to be less than minor

based on the site features and provided the measures described above are implemented.


measures (including planning and coordination of works, temporary traffic management and methods such

as combined trenches, directional drilling and routing of works) are undertaken.

The report identifies the potential for lighting effects from BAU and America’s Cup event lighting for Wynyard

Point, caused by the potential for spill and glare from new lighting, notably to sensitive sites such as

apartments and hotels. A number of mitigation measures, including use of zero tilt luminaries, and inclusion

of event lighting procedures in the Event Management Plan, are proposed. On the basis that these

measures are incorporated into conditions of consent, and given the existing environment against which the

proposal must be assessed, the potential effects of lighting can be appropriately managed.



3233847 // NZ1-15242902-18 0.18 // page 30

7.3 Effects of Wynyard Point Works

Similar to Marine Works, any adverse effects of stormwater and ITA discharge via stormwater in terms of

land use, discharge quantity and quality, and of HS use, storage and disposal are considered to be less than

minor based on the site features and provided the measures described above are implemented. The

proposed development has minor beneficial effects compared with the existing situation, as there is a

reduction in potential for sediment discharge, due to the proposed modern stormwater treatment and car

park removal and a reduction in the storage of HS with the removal of the Stolthaven South tank farm.


measures (such as planning and coordination of works, temporary traffic management and combined

trenches) are undertaken.

As for the Marine Works, the report identifies the potential for lighting effects from BAU and America’s Cup

event lighting for Wynyard Point, caused by the potential for spill and glare from new lighting. A number of

mitigation measures, including use of zero tilt luminaries, and inclusion of event lighting procedures in the

Event Management Plan, are proposed. On the basis that these measures are incorporated into conditions

of consent, and given the existing environment against which the proposal must be assessed, the potential

effects of lighting can be appropriately managed.

2 Concept Design

Beca tabled the latest concept design layout sketches showing the location of syndicate bases, relocated ferry and fishing fleet facilities and the proposed structures.

Four distinct locations with requirements for power were identified by Beca:



3. Extension to Wynyard Wharf South;


Indicative power requirements for the syndicate bases were discussed and approximated by Beca to be 1.2MVA in total for the 8 bases. Following discussions, a base assumption of 200kVA for the Emirates Team New Zealand (ETNZ) base and 150kVa for others was agreed. Vector advised that this requirement could likely be accommodated by the existing electrical infrastructure, with no network capacity issues foreseen.

Beca advised that the ETNZ base is the only base which would likely be permanent, with the others remaining in place for up to four years (should the 2021 defence be successful).

Vector illustrated landside locations in the area of each of the developments where syndicate bases were proposed, where 22 kVA / 400V (below ground) power lines and substations were already present and could be connected into to provide the syndicate bases with sufficient power.

However, it was noted existing supply to Hobson Wharf believed to be LV and closest may be near Princes Wharf/Quay St. May be potential to coordinate with other works currently ongoing/planned in the area.

Base 2 to 5 commercial aspects would need to be resolved with Panuku at a later date.


3233847 // NZ1-14915402-7 0.7

Vector advised on minimising the length of cable required to supply the syndicate bases on Wynyard Wharf.

Vector noted that the ferry facilities currently do not have a significant demand for power and as such, provision of power to the relocated facilities should not pose a challenge.

3 Superyacht Berths

Beca highlighted the areas proposed for superyacht berthing and tabled the PIANC guidance on electrical supply to superyacht berths. Approximate power demand magnitudes were discussed, along with two options for supply (due to the demand being very significant):

1. Development of the existing power network infrastructure;

2. Provision of generators to power the superyachts.

Vector noted that if network upgrades were to be considered, there are a number of developments in the wider area which would benefit from co-ordination.

Vector requested time to consider the residual capacity in the existing power network infrastructure and determine the magnitude of upgrades or adaptations required to be able to accommodate a number of superyachts. Vector to advise on this residual network capacity as soon as possible.

Vector advised that Panuku might wish to consider upgrades to the power network in the areas being considered to better accommodate larger vessels such as superyachts etc.

Vector: ASAP

4 Letter of Support

Beca to send an email to Vector containing the tabled sketches and additional details on power demand, superyacht vessel requirements, sizes and locations.

Vector to then follow up with a formal letter of support for the project and outlining Vectors ability to accommodate the project power requirements.

2 Concept Design


Four distinct locations with requirements for water/wastewater services were identified by Beca:



3. Extension to Wynyard Wharf South;


Beca advised that the ETNZ base is the only base which would likely be permanent, with the others remaining in place for up to four years (should the 2021 defence be successful).

Indicative figures for water supply demand at the syndicate bases and superyacht berths were discussed, including potable water supply, water for vessel wash-down, water for firefighting, and wastewater services for sanitary facilities and boatshed drainage. Following discussions, Watercare expressed an interest in seeing more figures that would help define peak flow rates, if possible, and any relevant records that might be available to the client or from previous AC events.

Watercare raised some concern about the discharge of vessel wash / clean potable water into the Stormwater drainage system or marine environment with regard to AUP OiP compliance.

Beca : ASAP

Beca to investigate


3233847 // NZ1-14919060-7 0.7

The concept design approach to water supply for firefighting at the syndicate bases was outlined by Beca and discussed, with the approach predominantly utilising water from the ocean via permanent dropper pipes. It was noted a supply of water sufficient for initial firefighting was likely to be required from the Watercare network.

Watercare illustrated landside locations in relatively close proximity to each of the developments where syndicate bases were proposed, where existing belowground infrastructure is present and with potential connection points.

It was noted that the existing water services infrastructure on Halsey Street Extension Wharf and Hobson Wharf are private and presumably owned and operated by Panuku. These wharf-based networks connect into the Watercare assets at locations on Jellicoe St and Hobson St.Watercare will review their belowground assets at the corner where Hobson St meets Quay St as it is unclear from the GIS plans where the public assets start and where the most appropriate point of connection would be.

Watercare noted that construction of the new pump station is currently underway near the corner of Daldy St and Pakenham St which will serve the vast majority of Wynyard Quarter. Completion of construction of this pumping station is likely to be in 2018.

Watercare also noted that the condition of the existing belowground infrastructure on Wynyard Point would benefit from a review prior to connection works being carried out. A CCTV condition survey assessment of the network on Wynyard Point would be of benefit due to the age of infrastructure.

Watercare requested Panuku contact details and expressed an interest in developing a Watercare/Panuku relationship and being involved and present at the consent stage to aid progress.

Hi Paul

Thanks for the meeting yesterday morning.

Please find below our comments regarding the latest Proposal for the Americas Cup 2021 bases.

Hobson Wharf – No change from previous comments offered.

Wynyard point – No change from previous comments offered.

Halsey Wharf - Utilising the Viaduct Event Centre for ETNZ’s base offers minimal extra challenges as it is an existing

building, the changes in the risk profile associated with the “change of use” need to be considered. The building is

currently a fully sprinklered structure with established BIC and Panel.

We see no reason for these locations to be changed.

With the introduction of the fenced compound on the northern corner of the building, the egress of persons

(spectators) off the wharf needs to considered and egress pathway designed to cope with the expected crowds.

Emergency access gates for fire appliance through this compound needs to be considered.

Water supply needs to be compliant with the COP.

General comments:

We would like to know what other structures (if any) are being proposed for the Halsey Wharf area? This could

impact on the risk profile for this area.

We understand the tight timelines that are involved with this project and do not want FENZ to be seen as causing

any undue delays to the process. Hence we encourage the designers to utilise our FEB process at an early stage.

Please contact me if you wish to discuss this further.

Regards

Barry

Hi Paul

Following up from our conversation this morning.

In relation to the AC36 “Karohirohi” option,– the final alternative scheme, the previous comments offered on behalf

of FENZ (see below) remain unchanged and valid.

In addition,

• The proposed increase in the maximum occupancy of the bases (up to 410) will need to be modelled to

prove evacuation times can be met.

• The reduction in width down to 7m for the private road at the north eastern end of the bases on Wynyard

point, will

• need to be maintained and kept clear of obstacles (parked vehicles etc) to ensure emergency access is

available at all times.

• The removal of the proposed ETNZ base from Hobson Wharf - no comment required.

Please contact me if you require further comment.

Again we appreciate the short timescale being asked again here

Called AC36 “Karohirohi” – the final alternative scheme being submitted for MBIE/ Panuku is on Friday (tomorrow )

– and is as attached. These 2 Fire Drawings again document key fire and egress aspects.

However, we / FENZ have actually reviewed these in parts of previous iterations:

1 The Wynyard Point arrangements are as per the last scheme to which you reviewed and commented 9 March (5

bases and BST / Stolthaven South gone/ Brigham St Closed )

2 The 2 base config on Halsey was part of an option reviewed prior to the iteration prior to 1 above (with different

arrangement on Wynyard)

3 The step change is thus a blend of 2 iterations- but ETNZ will move to a base on Halsey - and there will be no base

on Hobson .

The assessment report will still capture the other general comments made to previous schemes re public access and

occupancy , modelling on Halsey also for egress v access, emergency and evacuation plans, controls, water supplies

etc , and remaining Wynyard Point Hazards.

With respect to the latter, updated Sherpa and 4Risk reports do not require any special provisions for the buildings

now (given the set out and buffer zone / road) but residual risks on public access limitations to the area and the pier

need to be managed in the event of a fire / incident.

Happy to discuss over phone, but hopefully as this has been covered before, your review will be fairly simple , and

if you could comment by Friday morning that would be very much appreciated to make the submission complete

Regards

Paul

Hi Paul

Thanks for the opportunity to comment on this latest variation for the proposed AC bases to be located on Wynyard

Wharf.

Comment:

FENZ support this latest proposal.

From a risk reduction perspective, this is the best option that has been presented to us for comment to date.

With the removal of Stolthaven South and BST South from this area, the hazard profile that exists in other iterations

proposed will be markedly reduced.

There is very little change in our position from the three and four base options proposed earlier for this area (refer

to earlier comments).

• Emergency access requirements along Brigham st – no change

• If the proposed emergency access across the front of the bases (ex Brigham St) is compromised, the two 5 m

wide yard accesses shown would provide a viable secondary option for our fire appliances to the front of the

AC base buildings.

• The private road at the nor-eastern end of the bases provides a solid secondary access option for emergency

vehicles to any emergency event on Wynyard Point.

• Evacuation from the AC Bases –Fire protection systems (sprinkler systems) for the bases – unchanged from

previous comments.

• Brigade attendance points –BIC, due to this proposed layout, consideration could be given to having a

common BIC /arrival point for bases A and B, and bases C and D. Base E would be stand alone, but this point

is still open for discussion.

• Water Requirements – unchanged from previous comments.

As stated already, FENZ are open and available to discuss any further design concepts for the project.

Subject: AC36 Wynyard Point Option - proposed scheme - Further changes for comment

Hi Barry

We appreciate your time in reviewing the proposals at such short notice – and this a heads up

We have now been asked to formally submit the Wynyard Point alternative scheme based on 5 bases on Wynyard

Point Landside on Monday the 12th March. I hope you can accommodate a review prior, but I think we have covered

this mostly already.

Refer attached, and we are preparing Fire Drawings based on these layouts which I will send on – but this a heads

up;

1. BST South and Stolthaven South now both removed – so these high hazard risks go

2. 10m Access Road and Buffer zone as before to North – as before available for FENZ and also egress

3. Brigham St closed – but will have through access for FENZ and egress through all base yards

4. Will show BIC s as before to front of base buildings off Hamer

5. AC base occupancies max 300

Would welcome confirmation of any comments again, even prior to getting the Fire Drawings updated and to you

Thanks again

Paul

Hi Paul

Thanks for the opportunity to comment on this latest version of the Wynyard Point Option for the AC36 project.

And as per our discussion on this option,

Wynyard point – 1 base on the wharf and 3 bases landside on the old ASB carpark.

The following comments may need to be considered for this location in general:

We have a level of concern regarding the public access to this area during “major event days”.

A large scale evacuation from this area could be problematic if dealing with an event (spill or fire) in the tank farm

area.

Consideration needs to be given to the risks associated with area (Sherpa report), how to manage a mass evacuation

and how this will impact on an emergency vehicles responding into this area.

With the proposed relocation of the Ferry and Fishing Industry to the north-western side of Wynyard Point,

consideration needs to be given to appropriate water supplies at this location.

Previous comments remain unchanged for this area.

Halsey Wharf – 2 bases at this location.

I concur with your notes detailed below and we have no further comment on this area.

Hobson Wharf –

No change to previous FENZ comments on this location.

Subject: AC36 Wynyard Point Option - proposed scheme - FE drawings for comment

Hi Barry

It has now been decided that an alternative scheme to the Wynyard Basin option will be submitted (and next week

we have to issue out as part of process)

Called the Wynyard Point Option, but we have discussed, and you have commented on, variations to this Wynyard

Point Option since Christmas , but its final layout is now decided.

See attached for your review and comment, which are and being drawn up in CAD - as the fire FENZ and egress

drawings to be submitted with a tech report – but are based on previous considerations / comments to date

You will see that :

Hobson Wharf – 1 base - fundamentally no change to Basin Option which was previously reviewed

Wynyard Point - 1 base on wharf , 3 landside on old ASB car park. This is one base less than you just reviewed – and

Brigham St remains closed – but the fundamentals have been maintained - as we discussed / reviewed the other

week

Halsey Wharf – with 4 bases on Wynyard, and 1 on Hobson, only 2 bases now on Halsey, (so 7 in total) and it is here

you have never formally commented on the 2 base scheme (this since Basin Scheme which had 4)

I have indicated access requirements and FF provisions considered based on previous review.

It could still be a common BIC and FAP mimic for the 2 bases as we had discussed before (see MOM 05.12).

I have noted that public occupancy limits needs to be determined.

We will include comments in the text on Sprinklers, event plans and other provisions as per the MOM on basin

option with Roger

Would really appreciate if you could review and make any particular comments to this scheme now before next

Tuesday ?

Happy to talk on phone or meet up

Thanks again for your time on this

Paul

Thanks for your update on the Wynyard Point Option.

Comment are as follows:

• As stated in previous correspondence, the removal of Stolthaven South complex is the preferred option for

Fire and Emergency NZ.

• Maintaining an emergency access corridor (gated) for our fire appliances along Brigham St is acceptable to

our operations.

• Buffer Zones shown at the sides of the AC bases are engineered to an appropriate size for the perceived risk.

• The one way access road through the Buffer Zone on the north-eastern side of AC base 7 provides us with an

acceptable alternative access route to the northern end of Wynyard Point risks.

• All other comments made in the attached document relating to the Wynyard Point options (dated 23rd Jan

2018), remain valid.

Fire and Emergency NZ are keen to work with the scheme proponent on whatever option is selected to mitigate risk.

This latest update on the “Wynyard Point” option is the most suitable option to date of those proposed for AC bases

in this area.


Let me know if the planned meeting next week is still required.

Subject: Americas World Cup AC36 - Wynyard Point Option

Hi Barry

As we briefly discussed, an alternative option is now on the table for the Wynyard Point configuration which we

need to conclude assessment by mid next week

See attached

I have also included a mark-up (by Beca) on the considerations for these (FE-1003)

• Stolthaven haz tanks are removed and the land reused, with ASB, car park for 3 bases

• Buffer zones for remaining bulk fuel storage

• No high load public access on race / major days to Wynyard Point areas (controlled)

• Access road between Hamer and Brigham

• Brigham open, but access will need to be locally stopped /managed whilst boats go yard to water and back

• It remains that recommended all Sprinklered buildings

• It remains comments made on emergency plans etc

Any additional comments to this scheme welcome – we have pencilled in meet next week but if you comment prior

and don’t see the need to catch up let me know

AC 36-Wynard Point Options.

23rd January 2018

Fire and Emergency New Zealand Comments on proposals

Requested by Ms Hannah Keats – Senior Advisor, MBIE

Initial high level comments the Wynyard Point proposal provided by our National Operations

Manager – Paul Turner remain valid.

The Wynyard Point options requiring comment will result in Americas Cup (AC) base buildings being

located in three distinct areas:

• Halsey Street Extension Wharf

• Extension to Hobson Wharf

• And Wynyard Wharf/Point area (partial closure of Brigham Street)

Key considerations for Fire and Emergency are

Access

One of our primary concerns with this proposal is the reduction in access for our fire appliances

along Brigham Street to the northern end of Wynyard Point. This road provides Fire and Emergency

NZ staff with an alternative safe access route if we are required to manage an incident (fire, spill or

leak) in this tank farm area.

The proposal of the two way “link Road” between Hamer Street and Brigham Street between the

tank farm and the proposed AC Base 5 will provide us with a viable alternative option to the

northern end of Wynyard Point via Brigham Street.

This link road could potentially be compromised if we had a bulk flammable liquid fire near this road

with an unfavourable wind direction, (nor-easterly). If presented with these variables, we may need

to utilise an emergency access corridor through the hard stand areas of the proposed AC bases.

Any delays to our fire attacks in the tank farm area could potentially result in an increased impact on

the AC 36 event, environmental contamination (air and sea), higher level of disruption to the public

and general operations associated with this area.

Evacuation Strategies

An overall evacuation strategy for the combined site needs to be developed should a mass

evacuation be required for the overall AC 36 Village.

With this Wynyard Point proposal, I have been advised, the AC base buildings will have the ability to

cater for functions and other activities hosting up to 300 people at one time. Considering the risk

profile detailed in the ‘Sherpa Report”, careful consideration must be given to the number of people

and the activities these buildings will be used for.

The evacuation strategies for individual buildings should be developed to include two independent

egress pathways from the structures to the assembly areas. This provides flexibility for evacuation

of depending on the location and variables associated with the given emergency.

Building protection

As part of the risk mitigation for the structures, we strongly recommend the AC 36 Bases be sprinkler

protected structures and the system be designed and installed to the appropriate risk profile.

The sprinkler protection will minimise the damage to:

• The structure and help keep the fire isolated to building of origin

• Assist with the providing safer egress of occupants from the structure

• Minimise the impact on the AC 36 event

• Reduce the risk of fire spread and impact on neighbouring businesses.

Automatic Fire detection system should also be included in these buildings to provide early warning

of a fire for occupants.

Firefighting Water:

Available water for firefighting should be to up to the level detailed in the Code of Practices for

Firefighting Waters Supplies. Alternative options for firefighting water supplies can be discussed with

Fire and Emergency rep should this be required.

Risk Mitigation – Stolthaven South Operation.

Stolthaven South handles flammable liquids and low toxicity materials. The proposal to relocate this

operation to another site eliminates any risk posed from this site to the AC base structures and the

personnel operating in that area. Fire and Emergency NZ support this relocation option.

Should the relocation of Stolthaven South operation not be adopted, additional risk mitigation

options may be included in the AC 36 Base designs, people management processes, and surrounding

operations that will reduce the risk.

Fire and Emergency NZ will work with either option.

The remaining bulk flammable liquid storage facilities at this location should review their firefighting

infrastructure to ensure their facilities meets the “Industry best practice”.

Summary: Wynyard point options

• Fire and Emergency NZ are agreeable to the proposed two way link road between Hamer

and Brigham Streets as a workable solution for Emergency Vehicle accessing the northern

end of Wynyard point via Brigham Street.

• Firefighting water supplies are as per the Code of Practice.

• Appropriate evacuation strategies are developed for the AC Bases and the overall venue.

• We support the relocation of Stolthaven, but will work with the alternative if that is the

preferred option.

• The inclusion of the one way private link road on the Stolthaven south site could be useful

to emergency services operations given an incident in that area.

• Appropriate fire protection / detection systems be included in the AC base structures.

Fire and Emergency NZ are keen to work with the scheme proponent on whatever option is selected

to mitigate risk and address issues.

Item Action

1 Introductions

Introduction by Beca to the project, concept design and structural form, base layouts and agenda for the meeting.

A 3D visualisation of the proposed infrastructure (created by others) was viewed and discussed.

2 AC36 Concept


Three distinct areas of interest were identified by Beca:

1. Extension to Halsey Street Extension Wharf (HSEW)/ Western Viaduct Wharf;


3. Infill of sections of Wynyard Wharf South.

Layout, approximate geometry, structural form and timings were discussed.

Beca advised that the Emirates Team New Zealand (ETNZ) base on Hobson Wharf extension is the only base which would likely be permanent, with the others remaining in place for up to four years (should the 2021 defence be successful).

Beca also advised that hospitality events are anticipated at the (ETNZ) base on Hobson Wharf extension during the America’s Cup (AC) event.

It was noted that there are limited details currently available for syndicate base buildings, but it is anticipated that they are approx. 15m high, probably with more than one floor, most likely through inclusion of a mezzanine level.

3 Ambitions

Beca outlined a few key project ambitions, including:

1. Public access to the north face of the extended Halsey Street Extension Wharf / Western Viaduct Wharf and breakwater structures, for spectating;

2. Public access provided to the existing North Wharf, Karanga Plaza, Te Wero Island, Eastern Viaduct and Princes Wharf for spectating.

4 Firefighting at Syndicate Bases

Buildings on syndicate bases are effectively permanent from FENZ perspective.

RC made a strong recommendation for the syndicate base buildings to be provided with sprinkler systems, or high pressure misting systems due to the nature of the operations envisaged within syndicate base buildings, presence of flammable liquids and solvents, and burning characteristics of carbon fibre (significant amounts of which will be present in the bases). Once alight, carbon fibre burns well and produces dark, toxic smoke. As well as the inhalation risks, this can make visibility a problem when fighting the fire.

In addition to this, RC noted that there should be more than one evacuation point such that crowding down-wind of the smoke is avoided.

Due to the operations and materials noted above, in the syndicate bases, RC advised that sprinkler system design will likely require a high density of sprinklers, however they will reduce the peak firefighting flows required from the water network if compared to design for structures without sprinkler systems. A high pressure mist system would reduce the burden on the water network further, but with a higher capital cost.

RC advised that if sprinkler/mist systems are provided for one base, they should be provided for all, mindful of avoid liability issues for the race organisers and infrastructure owners and redundancy of sprinkler systems if adjacent buildings develop a significant fire.

It was noted by RC that the sprinkler system could be common throughout the bases, or zoned for each syndicate base. However, the smoke detectors should be zoned. Fire alarm panels were discussed and RC advised that individual panels or separation of alarm systems would be of benefit in determining in which base the fire has broken out. In the absence of this approach, emergency services arriving at the location would not know initially, in which syndicate base the alarm was activated.

RC also advised that a manual system whereby reliance is placed upon personnel activating the alarm, should be avoided where possible.

A main (repeater) panel in the area of the existing Viaduct Events Centre for bases 2-5 was discussed and agreed to be a sensible option.

Base 1 would have its own fire alarm panel, as would bases 6-8.

Separation (passive fire protection) of the syndicate bases was discussed, and the related building consent requirements. However, this is to be considered in more detail once the design progresses further, and syndicate buildings better defined.

For the syndicate bases on the extended Halsey Street Extension Wharf / New Western Viaduct Wharf, RC advised that 3 fire appliances would arrive in approximately 3 minutes to respond to the fire alarm. If the presence of a fire is confirmed, another 3 appliances would then be summoned. RC outlined the locations of the first, second and third appliances as likely being :

1. North of the Viaduct Events Centre, perhaps at the location of the main

(repeater) firefighting alarm panel (which would be of benefit);

2. On the south side of the Western Viaduct Wharf;

3. On the north side of the Halsey St Extension Wharf extension.

Appliance locations for syndicate base 1 on extended Hobson Wharf - 1 appliance on south side, 1 on north side. Similar approach for bases 6-8.

An over-arching Rapid Response Team (RRT) with responsibility for all the syndicate bases and wider AC event was recommended by RC. This would have a number of benefits for compliance with fire procedures (eg functioning of auto-opening gates) and general safety and security, and could be implemented once number of operational bases starts into increase – say 3+ bases operating.

It was noted that the RRT could be an extension of that which manages the fire risk for the silo/tank areas on Wynyard Point.

RC inquired if there is a sprinkler system in the maritime museum. Beca to investigate.

5 Access and Egress

Beca noted that syndicate bases and yards are secure facilities, and contents are sensitive, thus are not accessible to the general public.

RC raised the issue of crane operations during emergency. It was agreed that there should be a system in place whereby crane lifts are aborted at the sound of a fire alarm, with vessels returned to the water quickly and access routes made free from obstacles.

Mast laydown was discussed in relation to obstacles for fire appliances. It was noted by Beca that the mast was expected to accommodate this (Beca to confirm).

Access and egress was discussed in detail for syndicate bases on the Halsey and Hobson Wharf extensions :

A route was identified by RC to gain access to the northern side of the syndicate bases on the Halsey Wharf extension, via a marked corridor along the 8m wide access road. RC questioned the ability of fire appliances to turn this corner and noted that if sufficient space is provided, the fire appliances could also do a 3 point turn. The building corners could potentially be chamfered to accommodate this. Beca to check the swept path of a fire appliance turning this corner and 3 point turn and confirm.

RC noted that preferably the fire appliance would drive out forwards, via the 4.5m accessway further east.

Automated electronic gates (opening on fire alarm activation) would be required on bases 2-4 for fire appliance access and pedestrian egress.

It was agreed that the secondary egress (and egress only) routes would be utilised on the east of side of Halsey 4.5m and 2m.

Egress for pedestrians was identified as being via a marked corridor through the 8m access road, both accessways (2m and 4.5m) to the east, and (gated) emergency egress through base 2-4 (from 2m and 4.5m accessways), and base 5 (from breakwater and north face). This could be via automated electronic gates which open when the fire alarm sounds.

It was noted that when the AC race is in progress, the greatest crowding takes place, but is accompanied by a reduced fire risk due to the operations within the syndicate bases being reduced. Conversely, when the highest fire risk is present (most frequent and highest fire risk

activities in the syndicate bases – night time repairs), the anticipated number of general public on the wharves are reduced.

A turning circle location for fire appliances on Hobson Wharf extension was identified to the east of the syndicate base. Swept path to be checked by Beca.

Secondary egress from the Hobson Wharf extension was discussed by means of gangway access to the existing pontoons. This was agreed to be a potential back-up egress route.

Access and egress to the syndicate bases on Wynyard Wharf was noted to be much less restricted, with wide corridors available between buildings. However, a traffic management system will be required to facilitate egress of the public across the road as there is no footpath on the eastern of Brigham St. A RRT would be helpful for implementing this emergency traffic management.

RC questioned the structural capacity of North Wharf, Western Viaduct Wharf, Hobson Wharf and Wynyard Wharf for loading from fire appliances. Beca to investigate. Also review the potenital access route along the reclamation landward of North Wharf for accessing fires on yachts moored at North Wharf.

The operation of the Viaduct Events Centre (VEC) during the AC event was questioned by RC. Beca noted that it would likely be used for race organisation and media etc. Cabling, generators and parked vehicles would impede fire access. Measures will be required to control this such as hatched ‘no stopping’ areas on each side of the VEC, along with specific areas for storage of generators on the north or south side of the VEC.

6 Water Supply to Firefighting

RC advised new pump houses would be required for the sprinkler systems, and that firefighting inlets to be positioned at or near pump houses.

RC also noted that fire hydrants must remain available and accessible during every stage of the event, and under no means be obstructed by AC activities.

Existing hydrants on north face of existing HSEW will remain. Additional hydrants on the north face of the new HSEW extension are required, supplied by a ring main around the existing and new Halsey St/ Western Viaduct Wharves.

Droppers to harbour for seawater firefighting were discussed. RC noted that these are not a preferred option as there are associated maintenance issues with such systems, due to the rapid (within a few months) accretion of marine growth in the dropper pipe which blocks it, compromising its use.

RC inquired about the condition of the existing dropper pipes on Queens Wharf, and gave a contact name at the Wharf.

FENZ are in possession of a 2km hose carrier and as such could utilise water from the tank farm hydrants in Wynyard Quarter if need be. However, this asset is for contingency use and should not be considered as a design relief.

Marine vessel-based firefighting was raised by LC and discussed. Unlike in the previous AC event, no specific vessels are currently readily available to the FENZ. However, it is anticipated that services such as the police / coastguard / Department of Conservation could provide vessels to transport firefighting personnel if needed.
