Ethnic Peoples Advisory Panel 21 March 2013

Report Name: Waitematā Harbour Stormwater Network Discharge Consent – Stormwater Priorities Consultation

Purpose 1. To inform the Ethnic Peoples Advisory Panel about the Waitematā Harbour stormwater

network discharge consent (NDC) process, and obtain feedback on priorities and criteria for stormwater management.

Executive Summary 2. The Stormwater Unit is seeking feedback on priorities for stormwater management in the

Waitematā Harbour consolidated receiving environment (CREs) (i.e. the area of land draining to a coastal receiving environment, such as the Waitematā Harbour).

3. Stormwater drainage is a natural process where rainwater flows by gravity across or through the ground to drains, streams, lakes, groundwater or wetlands and ultimately to the coast, or underground aquifers in some areas of Auckland. Urbanisation modifies this natural process. As a city develops the area covered by impervious surfaces also grows. This increases the quantity of water that runs off as surface flows, and the potential for flooding and erosion. Removal of streamside vegetation has also reduced the quality of urban streams. Many urban streams have previously been piped or lined with concrete during development to efficiently convey stormwater runoff and minimise erosion. As a result the extent of urban streams has been severely reduced and many areas lack a connected network of natural open stream channels, particularly in the central Auckland isthmus.

4. A number of stormwater issues have been identified around the Waitematā Harbour. These include managing growth, managing infrastructure and assets, managing flooding (or the risk of flooding), urban stream management, contamination of the estuaries and harbour, managing stormwater discharges to groundwater, and stormwater effects on the wastewater network.

5. The Stormwater Unit is aware that stakeholders with an interest in the Waitematā Harbour CRE have already been extensively consulted at a high-level for strategic planning documents such as the Auckland Plan. The past consultative effort, with respect to stormwater management, has informed the development the application documents. As a result, the Unit will attempt to avoid consulting on issues which have already been previously discussed. The Waitematā Harbour CRE NDC Consultation Process is therefore focusing on two specific questions for consultation:

a) From the stormwater issues identified, what do you think are the priorities for the Waitematā Harbour CRE and what must be most urgently addressed?

b) From the Stormwater Unit’s responsibilities, what do you think are the criteria that Council should use for selecting stormwater management priorities?

6. The Stormwater Unit would like to obtain feedback from the Ethnic Peoples Advisory Panel in relation to these two questions. Feedback received from the consultation process will be summarised and will help to inform the setting of priorities for the network consent application. Based on priority issues and the selected criteria for prioritisation, a “best practicable option” approach to managing stormwater discharges from the public network will be developed.

27

Recommendation/s That the Ethnic Peoples Advisory Panel:

a) receive the report;

b) consider providing feedback to the Stormwater Unit by the end of April 2013;

c) consider whether or not they would like to receive a presentation on the Waitematā Harbour stormwater NDC Consultation process.

d) consider whether or not they would like to receive an update on the outcomes of the Waitematā Harbour stormwater NDC Consultation process.

e) consider whether or not they would like to receive future agenda items on subsequent stormwater network discharge consents.

Discussion Background

7. Stormwater drainage is a natural process where rainwater flows by gravity across or through the ground to drains, streams, lakes, groundwater or wetlands and ultimately to the coast, or underground aquifers in some areas of Auckland. Urbanisation modifies this natural process. As a city develops the area covered by impervious surfaces also grows. This increases the quantity of water that runs off as surface flows, and the potential for flooding and erosion. Removal of streamside vegetation has also reduced the quality of urban streams. Many urban streams have previously been piped or lined with concrete during development to efficiently convey stormwater runoff and minimise erosion. As a result the extent of urban streams has been severely reduced and many areas lack a connected network of natural open stream channels, particularly in the central Auckland isthmus.

8. Contaminants are picked up by stormwater as it travels across the land, and passes through natural and man-made drainage systems. The primary contaminants of concern in the Auckland Region are sediment (soil particles), copper, zinc, lead and polycyclic aromatic hydrocarbons. These contaminants can be toxic to aquatic life, and cause harm as they are dispersed in the aquatic environment.

9. The Auckland isthmus differs from the rest of Auckland in that a large proportion of the city is located on groundwater aquifers. These aquifers play an important role in stormwater disposal, as well as supplying some of Auckland’s drinking water.

10. Many of these adverse effects are already occurring. The stormwater network discharge consents provide an opportunity to create a framework for managing and mitigating these identified effects to Auckland’s stream and coastal environment, and its public stormwater network.

11. It is neither practically possible nor affordable to address all the negative effects of stormwater discharges, including existing effects, within the next 35 years (the duration of a stormwater network consent). Effort and resources therefore need to be directed to where we can make the most difference, in accordance with identified priorities.

The Waitematā Harbour Stormwater Network Discharge Consent

12. The Auckland Council Stormwater Unit is required under the Resource Management Act (1991) to obtain resource consents to discharge stormwater from the region’s stormwater network into the natural environment. Under the Auckland Regional Plan: Air Land and Water and the Auckland Regional Plan: Coastal, stormwater discharge consents from the public stormwater network are called stormwater network discharge consents.

28


13. A high level, broad-scale assessment approach to stormwater network discharge consents is being proposed, which focuses on outcomes for Consolidated Receiving Environments (CREs) (i.e. the area of land draining to a distinct marine receiving environment or coastal catchment). Ten CREs have been identified for the Auckland region, and the first CRE to be considered is the Waitematā Harbour (see Figure 1). The Waitematā Harbour CRE priorities are important to the long term wellbeing and interests of a large number of people.

14. The Waitematā Harbour consolidated receiving environment covers around 45,000ha and contains one of the earliest and most intensely urbanised areas in New Zealand. There are 54 sub-catchments, approximately 2,204km of reticulated pipelines, 58,403 manholes and 15,896 catchpits. There is an estimated 800km to 1100km of open streams which drain, via estuaries, to the Waitematā Harbour. The Waitematā stormwater network discharge consent application focusses on priorities within the urban areas of the Waitematā Harbour consolidated receiving environment.

15. Auckland Council has published three documents explaining consultation surrounding the Waitematā Harbour network discharge consent stormwater priorities, issues and criteria:

a) Waitematā Harbour Stormwater Network Discharge Consent - Information Brochure and Request for Feedback

b) Frequently Asked Questions – including a list of detailed responses to the frequently asked questions about this project.

c) The Waitematā Harbour Stormwater Network Discharge Consent Consultation Summary Report – a detailed technical report regarding the challenges of managing the stormwater draining into the Waitematā Harbour. This report contains details regarding key issues within the Waitematā Harbour CRE, along with an explanation

Figure 1: Location of the Waitematā Harbour consolidated receiving environment

of the potential criteria for prioritisation (as shown in the tables associated with paragraphs 17 and 18 of this report).

16. These documents are attached to this report.

Questions for Consultation

17. The Auckland Council Stormwater Unit would like you to provide feedback and input into which of the following stormwater issues around the Waitematā Harbour are the highest priorities:

ISSUE Your Priority Ranking (please rank 1 – 7, where 1 is the most urgent and 7 the least urgent)

Managing growth Managing our infrastructure/ assets Managing flooding (or the risk of flooding) Managing urban streams Contamination of the estuaries and the Harbour Managing stormwater discharges to groundwater Reducing stormwater effects on the wastewater network

18. You are also asked to provide your views on the criteria that guide how, through this network discharge consent process, Auckland Council selects its priorities for stormwater management in the Waitematā Harbour and its associated sub-catchments (i.e. stream catchment areas). This criteria are tabulated below and can be ranked according to priority:

19.

MANAGING GROWTH

Proposed Criteria for selecting priorities Your Ranking (H, M, L)

Prevent/ minimise effects from future development Focus effort in growth areas within sensitive receiving environments Intensification and re-development:

(a) Council-identified priorities (b) Opportunity-driven network upgrades (c) Easy wins (d) Market led (e) Development led

MANAGING OUR INFRASTRUCTURE / ASSETS

Proposed Criteria for Selecting Priorities Your Ranking (H, M, L)

Asset condition, age and criticality (i.e. a potential for asset failure) Growth opportunities (improve stormwater assets as development occurs) Asset information (improving collection of robust asset information) Impacts on existing communities (not meeting expected levels of service)

MANAGING FLOODING AND THE RISK OF FLOODING


Frequency of flooding (a risk based approach to managing flooding issues) Existing flooding and damage Cost to manage flooding issues Redevelopment opportunities Multiple benefits of flooding projects to amenity, recreation and cultural values

30


MANAGING URBAN STREAMS


Ease of intervention (zoning, ownership and access) Ecological values Level of active community support Opportunities to leverage outcomes (linkages with other projects) Cultural significance (mauri of the water and history of the locality) Landscape integration and enhancement (create a community focal point)

CONTAMINATION OF THE ESTUARIES AND HARBOUR


Existing contaminant levels (to limit further degradation) Actual trends in contamination (where the highest level of change is predicted)

Contaminant loads Marine ecology (using benthic/seabed animals as an indicator of priority) Focus on areas of amenity, aesthetics and use Cultural significance (mauri of the water and history of the locality) Holistic contaminant management (with other organisations and agencies)

GROUNDWATER MANAGEMENT


Improved soakage performance in groundwater take areas Prior treatment of stormwater into ground in targeted areas Improved management of groundwater as opportunities arise

REDUCING STORMWATER EFFECTS ON THE WASTEWATER NETWORK


Public health risk (needs alignment with Watercare Services) Environmental risk (needs alignment with Watercare Services) Watercare opportunities taken as they arise (to work with council’s CCO) The Mauri of water (its life-force or life-giving principle is valued by Māori)

20. A description of the identified issues and criteria can be found in the Waitematā Harbour Network Discharge Consent Summary Document attached to this report.

21. If this project is considered of interest to the Panel, a feedback form has been attached to this agenda report and can be completed. Alternatively, general feedback and comment through the meeting would be welcomed.

How will the stormwater network discharge consents affect you?

22. Consolidation of the numerous authorisations will assist Auckland Council and developers by simplifying management of the consent process. The stormwater network consents will set parameters around priorities for stormwater management, and guide sub-catchment (i.e. individual stream catchments within the greater consolidated receiving environment) planning initiatives. In addition, it will assist with directing Council as to where physical works will be undertaken to improve stormwater management. The type and scale of various development activities, which can take place around the Waitematā Harbour, will still be governed by the limitations already set in the existing (e.g. the district plans) and proposed planning documents (e.g. the Unitary Plan).

31


Consideration

Local Board Views 23. Feedback is currently being sought from the local boards around the Waitematā Harbour,

and a local board cluster workshop is scheduled to be held on 22 March 2013.

Maori Impact Statement 24. Feedback is currently being sought from iwi Maori and a number of workshops with Maori

are schedule to be held towards the end of March and beginning of April 2013.

General 25. General consultation with key identified stakeholders within the Waitematā Harbour

catchment area (including internal Auckland Council staff, interested advisory panels, council-controlled organisations, government departments, environmental and recreational interest groups, community and business interest groups and the general public) is also being undertaken at present.

Implementation Issues 26. Three risks with respect to implementation of feedback from this Panel have been

identified. Firstly, it is noted that a wide range of stakeholders are being consulted. As a result, it is likely that there will be differing opinions with respect to stormwater management priorities. Secondly, there is a risk that there will be a lack of funding to implement all identified priorities. Thirdly, since the Waitematā Harbour stormwater network discharge consent application will be going through a regulatory process under the Resource Management Act (1991), and any outcomes may be open to challenge through this process.

ForewordForewordForewordForeword

This is your chance to assist Auckland Council’s Stormwater Unit in establishing priorities for

stormwater management through the Waitematā Harbour stormwater network discharge consent

process.

In te reo, Waitematā means sparkling waters, and the harbour and the streams that feed into it all

have significant cultural value to the various iwi and hapu, and the Auckland community as a whole,

that have made it their home for hundreds of years. The spiritual connection that we have is a

reflection of the vital role that this special place has in all our lives.

However, increasing levels of human activity around the harbour have degraded its environment and

caused stream erosion and flooding problems. Contaminants (pollution) in the form of excess

sediment, metals (such as zinc and copper), oils and litter has been washed into the harbour via the

urban stormwater system and our streams. Careful management of land based activities, such as

development through good land use practices, can help prevent this harm.

The Stormwater Unit is committed to the Auckland Plan vision to become the world’s most liveable

city. To be a liveable city we need to achieve a “water sensitive community”. The Stormwater Unit

key objectives of safe communities, supporting growth, and healthy and connected waterways are

leading into a water sensitive community. Key functions of the Stormwater Unit are to manage

5,900km of pipe network, 10,000 km of streams, and to look after assets worth over $2.5 billion.

The Auckland Council Stormwater Unit would like you to provide feedback and input into which of

the following stormwater issues around the Waitematā Harbour are the highest priorities:

• managing growth,

• managing infrastructure/ assets,

• managing flooding (or the risk of flooding),

• urban stream management,

• contamination of the estuaries and harbour,

• managing stormwater discharges to groundwater, and

• stormwater effects on the wastewater network.

You will also be asked to provide your views on the criteria that guide how, through this network

discharge consent process, Auckland Council selects its priorities for stormwater management in the

Waitematā Harbour and its associated sub-catchments (i.e. stream catchment areas).

This feedback will provide important information for the Waitematā Harbour stormwater network

discharge consent, a resource consent that will allow Auckland Council to continue discharging

stormwater into the Waitematā Harbour and its contributing streams. Your feedback will assist in

1.01.01.01.0 Background and IntroductionBackground and IntroductionBackground and IntroductionBackground and Introduction

The Auckland Council Stormwater Unit is required under the Resource Management Act

(1991) to obtain resource consents to discharge stormwater (water and contaminants) from

the region’s stormwater network into the natural environment. This authorisation of

stormwater discharges from the public network is known as a stormwater network discharge

consent (NDC) under the Auckland Regional Plan: Air Land and Water and the Auckland

Regional Plan: Coastal. Council is applying for a stormwater NDC consent to authorise the

following activities:

• diversion and discharge of stormwater from existing and potential future public

networks within urban areas, and in rural and coastal settlements; and

• discharge of contaminants.

At present, policies relating to NDCs are set out in the Auckland Regional Plan: Air Land and

Water, and the Auckland Regional Plan: Coastal. Figure 1 illustrates the relationship between

NDCs, Council policies, processes and statutory documents.

Figure 1 The relationship between NDCs and Auckland Council policies, processes and statutory documents.

Attachment A


Auckland Council has designed a high level, broad-scale assessment approach to stormwater

NDCs, focusing on outcomes for consolidated receiving environments (CREs). This approach

focusses on where the Stormwater Unit should prioritise expenditure and effort in order to

address key identified effects and issues. Ten CREs have been identified for the Auckland

region (Figure 2). This Consultation Summary Document focuses on the first CRE to be

considered: the Waitematā Harbour. The Waitematā Harbour NDC priorities are important to

the long term wellbeing and interests of a large number of people.

This Consultation Summary Document covers the following:

1. Explanation of the consultation process for this application (Section 2.0),

2. Explanation of the Auckland Council Stormwater Unit and its function (Section 3.0),

3. Summary of the consenting approach for the Council’s public stormwater infrastructure (Section 4.0),

4. Outline of the key stormwater issues of the Waitematā Harbour (Section 5.0), and

5. Provision of proposed criteria for prioritising the management of these issues, as the basis of your feedback (Section 6.0).

2.02.02.02.0 The Consultation ProcessThe Consultation ProcessThe Consultation ProcessThe Consultation Process

The Auckland Council Stormwater Unit intends that the stormwater NDC application for each

CRE is preceded by well-designed and focused consultation, resulting in quality engagement

with stakeholders that strengthens and consolidates the long term relationships needed for

on-going sub-catchment-based initiatives following the consent. As a result, a Consultation

Implementation Plan has been prepared for the Waitematā Harbour NDC application. The

goal of this Consultation Implementation Plan is:

To design an effective, efficient, best-practice high-level consultation process for the

Waitematā Harbour NDC that is genuinely engaging, useful to all parties, contributes

to long-term relationship-building that gives effect to the Auckland Plan, and that

fulfils the requirements of the consent process.

The consultation process outlined in the Consultation Implementation Plan for the Waitematā

Harbour NDC is centred on a core issue under consideration:

In managing stormwater discharges for the Waitematā Harbour CRE, what should the high-

level management priorities of the Auckland Council be?

The Stormwater Unit is aware that stakeholders with an interest in the Waitematā Harbour

CRE have already been extensively consulted at a high-level for strategic planning documents

such as the Auckland Plan, and the past consultative effort, with respect to stormwater

management, has informed the development of the application documents. As a result, the

Unit will attempt to avoid consulting on issues which have already been consulted on.

The Waitematā Harbour NDC Consultation Process is therefore focusing on two specific

questions for consultation:



2. From the Stormwater Unit’s responsibilities, what do you think are the criteriacriteriacriteriacriteria that

council should use for selecting stormwater management priorities?

The Stormwater Unit would like to obtain feedback on these two questions in relation to the

Waitematā Harbour NDC application documents. Specific and relevant information from the

Waitematā Harbour NDC application is included in Sections 5 and 6 of this report.

There are certain aspects of the NDC which will not be consulted on, namely:

• High level regional issues, visions, objectives and outcomes as these pertain to

stormwater because these have already been agreed to and are already determined by

pre-existing plans and policies; and

Attachment A


• The NDC’s objectives and outcomes as these are specific, management-focused,

numerous, and will be derived from the priorities.

The Stormwater Unit is applying for a non-notified consent on the basis that:

• The Auckland Regional Plan: Air, Land and Water specifically provides for these

consents to be non-notified;

• The NDC is essential infrastructure and stormwater discharges cannot be stopped;

• Consultation at the CRE level is expected to be high-level, engaging and thorough,

delivering a transparent process and contributing to a high-quality consent application;

• Consultation will be on-going with stakeholders, as the process moves down from the

high-level consent to detailed sub-catchment-based studies and then project-based

consents; and

• Stakeholders have already been extensively and recently consulted for several other

high level documents, as detailed above, as well as for the previous Council-led sub-

catchment-based work that makes up the CRE.

Overall, consultation will be undertaken within a defined timeframe, and the Stormwater Unit

hopes to lodge the application in 2013.

As mentioned previously, consultation on the Waitematā Harbour NDC application is only the

first step in developing a long term relationship with the Stormwater Unit’s stakeholders. The

Unit is committed to on-going consultation with stakeholders through the sub-catchment

management planning process, and is willing to make this commitment one of the conditions

of the NDC consent.

forms, and relevant Council contact details) is available on Council’s website at:

Council is currently consulting on, or will be consulting on, a number of other planning

initiatives such as the Unitary Plan, National Freshwater Policy Statement, the Water Strategy,

and the Marine Special Plan. As a result, the Unit will attempt not to revisit those issues

which have already been consulted on. The Council is currently developing a roadmap for

aligning future consultation around these projects. Some stakeholders have already provided

input to previous City and District council consent processes. However, under the Auckland

Council we are seeking to identify issues and priorities across the legacy council areas that

contribute to the Waitematā stormwater network consent process.

Auckland Council’s Stormwater Unit (“the Unit”) manages a network of natural assets and

approximately $2.5 billion worth of built infrastructure (including pipes, detention and

treatment devices, outfalls, culverts and channels), and also leads best practice stormwater

management advice for Auckland Council. The Unit is responsible for the operation of this

regional stormwater network and managing its effects, as outlined in the 2010 amendment of

the Local Government Act 2002. This includes the operation, maintenance and management

of the region’s public stormwater infrastructure and natural assets on public land, except for

some assets in the road corridors.

Other entities also manage stormwater assets. Assets located in parks and reserves are jointly

maintained by the Stormwater Unit and the Parks, Sports and Recreation Department.

Auckland Transport owns assets in road corridors and it has been agreed to let the Stormwater

Unit maintain these assets. This will help to ensure consistent maintenance practices and to

optimise maintenance costs. Watercare Services Ltd manages the water supply, wastewater

and combined sewer networks. A variety of private entities own and maintain stormwater

assets, including stormwater reticulation and water quality devices. In addition, streams on

private land are the management responsibility of property owners.

3.23.23.23.2 Stormwater Unit ExpenditureStormwater Unit ExpenditureStormwater Unit ExpenditureStormwater Unit Expenditure

Key functions of the Stormwater Unit are to manage 5,900km of piped network, 10,000 km of

streams. The level of expenditure allocated to the Stormwater Unit for meeting its key

functions and objectives is undertaken through the long term planning process, and is

currently defined in the Long Term Plan (LTP) 2012 – 2022. In addition to the LTP, the

Stormwater Unit undertakes asset management planning. The purpose of the Asset

Management Plan (AMP) is to ensure that present and future customer service requirements

are met, while managing assets in the most cost effective manner. Amongst other things, the

AMP outlines the long-term strategy for management of Auckland Council assets, levels of

service, performance measures and targets, management of growth, financial implications for

delivery of levels of service and growth, compliance and key areas for improvement.

The total capital expenditure for 2012/13 is about $50 million and is distributed across the

different stormwater programmes as illustrated in Figure 3. It is noted that the flood

protection programme accounts for the largest portion of the first year’s expenditure – 27%,

with asset renewal accounting for about 23% of expenditure. The environmental

improvement programme (water quality) accounts for 12% of the total budget.

Attachment A

Management Plan 2012/32)

Table 1 Capital work investment programme (Auckland Council Stormwater Asset Management Plan 2012/32)

Attachment A


Table 1 is taken from the AMP and forecasts the capital expenditure needed over the next 20

years to accommodate growth and maintain current levels of service. The Stormwater AMP

notes that the first 10 years of expenditure is aligned with the LTP 2012, but that there are

significant gaps between stormwater requirements to meet levels of service, and manage

stormwater effects, and LTP budgets in some expenditure categories in the future.

Given this funding gap, and the fact that it is neither practically possible nor affordable to

address all the negative effects of stormwater discharges, including existing effects, within the

next 35 years (the duration of a stormwater network consent), effort and resources will need

to be directed to where we can make the most difference, in accordance with identified

priorities.

The stormwater network discharge consents therefore provide Council with an opportunity to

create a prioritised framework for managing and mitigating stormwater effects to Auckland’s

stream and coastal environment, and its public stormwater network.

3.33.33.33.3 The Stormwater Unit DirectionThe Stormwater Unit DirectionThe Stormwater Unit DirectionThe Stormwater Unit Direction

The Stormwater Unit is fully committed to the Auckland Plan vision to become the world’s

most liveable city. Good management of stormwater and freshwater is an integral part of a

liveable city. Accordingly, the Stormwater Unit’s vision is a ‘water sensitive community’.

Therefore, the core Stormwater Unit objectives as illustrated in Figure 4 are:

• safe communities;

• supporting growth; and

• healthy and connected waterways.

Based on this vision, a number of Auckland Plan principles underpin and guide the Stormwater

Unit’s approach to Stormwater Management:

At present, the discharges of stormwater from Council’s stormwater network are covered by a

range of authorisations including Existing Authorisations (and applications), comprehensive

catchment consents, stormwater discharge consents and recent NDCs.

These authorisations vary in their age and the activities they cover. Importantly, stormwater

discharges over approximately half of the region’s urban area are subject to consent

applications that are more than 11 years old, some of which have not been significantly

progressed.

The Stormwater Unit considers this situation to be unsatisfactory. A patchwork of consents

and other authorisations is complex, inefficient and confusing, and leads to different

requirement across the region. In addition, the age of many of the earlier consents means

that, in some instances, they may be counter-productive to achieving good stormwater

management outcomes in that their provisions may no longer be relevant to the stormwater

management needs of the catchment and the improved understanding of stormwater effects.

As a result, the Stormwater Unit is committed to progressing network consents across the

region as a matter of priority. The NDC Framework provides the overarching approach,

direction, priorities and anticipated timing for the new NDCs. The NDC priority and estimated

timeframe is shown in Table 2 below:

The Framework takes a four-tiered approach to planning and network discharge consenting.

This framework describes how regional stormwater planning and operations will be managed,

and sets objectives, strategies and actions for stormwater management at regional, sub-

regional (CRE), stream catchment (CRE sub-catchment) and programme/ project levels. NDCs

are critical, mid-level components of that framework. Figure 4 shows the four levels together

with the outputs from these levels that contribute to the best practicable option (BPO). As

can be seen by this diagram (Figure 5), some stormwater management options are

appropriately assessed implemented at the regional level. These options include land use

planning and implementation (District, Regional and Unitary Plan), and region-wide initiatives.

At the sub-regional/ CRE level, the focus is primarily on identifying priority sub-catchments

and areas for more detailed investigation. Prioritisation will be undertaken as part of each

NDC application, and will be specific to each CRE.

Attachment A


At the stream or sub-catchment level, the focus is on developing detailed solutions to the

priority issues identified through the NDC and working at a local level to develop solutions

that, where possible, are integrated with local initiatives to deliver multiple benefits.

The 4th and final level is the programme/ project level where solutions are delivered “on-the-

ground”.

4.24.24.24.2 Consents RequiredConsents RequiredConsents RequiredConsents Required

The NDC is being sought as a restricted discretionary activity in accordance with Rule 5.5.11

of the Auckland Regional Plan: Air Land and Water, and Auckland Regional Plan: Coastal.

Council is applying for the following activities to form part of the NDC:

• the diversion of surface water in urban areas, and coastal and rural settlements (this

includes diversions associated with Auckland Transport’s urban road networks, and

state highways in urban areas where the stormwater discharges to the Council’s

network); and

• existing and future stormwater discharges from the Council’s stormwater network in

urban areas and coastal and rural settlements. This includes stormwater discharges

from the Auckland Transport road network in these areas, including those where

stormwater is discharged via a dedicated road asset. Stormwater discharges from the

state highway network that enter Council’s stormwater network are also included in

the NDC. Stormwater discharges include those to streams, rivers and lakes; the coastal

marine area; to land and groundwater; and include the contaminants normally

associated with urban runoff.

The network resource consent application will not seek consent for operation and

maintenance activities in the CMA or within streams, new structures, existing structures (as

these are generally permitted activities), private stormwater discharges that do not enter the

public network, discharge of contaminants from industrial premises, discharge of wastewater

and associated contaminants, stormwater from state highways that goes directly to streams,

the coast or ground, the accidental discharge of contaminants, and runoff from rural land.

5.15.15.15.1 IntroductionIntroductionIntroductionIntroduction

Stormwater drainage is a natural process in which rainwater flows by gravity across or through

the ground to groundwater, formal drains, streams, lakes, wetlands and ultimately to the

coast. Urbanisation modifies this natural process. As a city develops the area covered by

impervious surfaces (i.e. surfaces which do not allow rainfall to infiltrate the earth, such as

roads and roofs) also grows. This increases the quantity of water that runs off as surface

flows. Importantly, impervious surfaces also make the water runoff faster so that in heavy

rainfall, peak flows can be significantly larger than natural flows. This increases the potential

for flooding and erosion.

Urban streams are often piped, lined and channelized during development to convey

stormwater runoff and minimise erosion. As a consequence, many areas lack a contiguous

network of open stream channels and the extent of urban streams has been severely reduced,

particularly in the central Auckland isthmus.

Contaminants and sediment become entrained in stormwater as it flows from the land, and

through natural and artificial drainage systems. The type and amount of chemical

contaminants present in stormwater runoff varies in relation to the activities occurring in the

catchment and contaminant management practices. The primary contaminants of concern in

the Auckland Region are sediments, copper, zinc, lead, and polycyclic aromatic hydrocarbons

(PAHs - these are pollutants caused by the incomplete burning of coal, oil and tar – see the

Auckland Regional Plan: Coastal). These contaminants attach to sediment and organic

particles, and are dispersed and accumulated in depositional areas in the coastal zone. The

build-up of contaminants in sediments can be toxic to aquatic life.

The Auckland isthmus is also unique in that a large proportion of the city is located on the

lava flows. As lava cooled, cracks, joints and caves were formed in the basalt rock. Rain falling

in these areas soaks into the ground and flows through the fractures, where it is stored in

groundwater aquifers that ultimately flow to nearby streams or the coast. Where available,

these aquifers play an important role in stormwater disposal.

Effects from stormwater discharges are therefore linked closely to landuse, both in terms of

the type of landuse (e.g. residential, industrial or commercial), as well as the amount of

impervious area.

The purpose of the stormwater network discharge consents is therefore to avoid, remedy or

mitigate identified quality and quantity effects from Auckland’s public stormwater network.

The remainder of this section focusses on describing the stormwater issues and effects within

the Waitematā Harbour CRE (Figure 6).

5.25.25.25.2 The The The The WaitematWaitematWaitematWaitematā Harbour CREHarbour CREHarbour CREHarbour CRE

The Waitematā Harbour CRE covers around 45,000 ha and contains one of the earliest and

most intensely urbanised areas in New Zealand. Māori have occupied the area since their

arrival in Aotearoa around 700 years ago. European settlement began along the shores of

central Auckland in the 1840s and expanded out over the next 170 years. Urban development

has led to the alteration and loss of many natural features, as land was modified and

infrastructure built to support the needs of a growing city. Over much of the city’s history,

the environmental effects of stormwater, and measures taken to manage stormwater run-off

were not widely appreciated, and as a consequence, were not actively managed. Rather, the

focus for stormwater management over much of this period was on drainage, flood reduction

and sewage disposal. The history of development is therefore reflected in the extent,

characteristics and condition of the city’s stormwater infrastructure and its natural

environment.

Stormwater is only one of many issues that adversely affect the natural environment in the

Waitematā Harbour CRE. The combined effect of multiple activities has radically altered its

land, streams and coast. Today the Waitematā Harbour CRE contains a mix of landuses

ranging from:

Attachment A


• urban areas with commercial, industrial and residential development and supporting

infrastructure;

• rural and coastal townships of varying sizes;

• urban parks;

• exotic forests, plantings and scrub;

• native forest and scrub;

• rural areas with agricultural and horticultural landuse.

There are 54 sub-catchments which comprise the Waitematā Harbour CRE and these are

shown in Figure 7. These areas are important as the NDC will eventually be supported by finer

scale sub-catchment management plans for priority sub-catchments, which will be

progressively produced over the coming years. Those plans will identify specific solutions for

addressing the priority issues identified in the Waitematā Harbour CRE. Each sub-catchment

management plan will also be tailored to reflect the outcomes sought by local communities

(e.g. by giving effect to Local Board Plans). The sequencing and focus of sub-catchment

management plans will be based on the location, magnitude, characteristics and prioritisation

of the stormwater issues identified through this process.

5.3.15.3.15.3.15.3.1 GrowthGrowthGrowthGrowth

The Auckland Plan seeks to accommodate future population growth through the development

of a quality compact urban environment with well-designed, higher-density development in

the right places. Population increases will mainly occur within specific growth nodes, rather

than being evenly spread throughout the CRE (Figure 8). The desire for a compact urban form,

and targeting development around specific growth nodes, has a number of implications for

network utilities and the natural environment in the Waitematā Harbour CRE. Namely:

• Urban land and associated resources will be used more proficiently than in the past.

• Surrounding natural and productive land values will be safeguarded by constraining the

urban footprint.

• Remaining natural values within the metropolitan area will be subject to on-going

pressure. Provisions are required to retain, or where possible, improve those values.

• Existing urban areas in the catchment are already subject to infrastructural constraints.

Further development will exacerbate those problems unless network utilities are

Attachment A


upgraded, particularly in brownfield areas where higher density housing and business

activity will occur.

• Re-development creates an opportunity to improve both levels of service for urban

infrastructure and environmental outcomes.

• Innovative urban design is required to create safe, attractive, functional, resilient and

vibrant urban settings, while minimising the effects of development on natural values.

• Advanced engineering and land development techniques are required to provide

network resilience and prevent the mistakes of the past being made in greenfield areas.

Effective land use planning, coupled with Council and community led initiatives is required to

ensure that the positive aspects of the compact city growth form are fully realised.

5.3.1.15.3.1.15.3.1.15.3.1.1 Key Growth IssuesKey Growth IssuesKey Growth IssuesKey Growth Issues

Future greenfield areas, as well as infill and intensification, has been identified for parts of the

Waitematā Harbour CRE, and the way the CRE grows and develops can have an effect on the

quality and health of our receiving environments, and public safety of our communities. Four

issues have been identified relating to growth:

1. Development of greenfield areas can compromise receiving environment values and

degrade habitats.

2. Significant infill and intensification is identified for parts of the Waitematā Harbour

CRE. Infill development puts pressure on existing networks and can compromise levels

of service, which leads to more frequent and severe flooding, increased contaminants

and waterway erosion.

3. Development tends to occur in an ad-hoc manner, primarily driven by external factors

such as private and public developers.

4. Ad hoc development can also lead to developments in floodplains which causes other

stormwater issues such as flooding and effects on aquatic habitats.

The stormwater system consists of natural and built assets. Natural stormwater assets include

streams, aquifers and some overland flow paths. Built assets generally include the reticulated

network, open channels and stormwater treatment devices. The road network is an integral

part of the stormwater system as it conveys overland stormwater flows and frequently

receives stormwater discharges through kerb outlets. The road drainage system can then

become the primary means for disposal of stormwater away from properties.

The Stormwater Unit owns and manages the region’s stormwater built assets including

approximately 5,900 km of reticulated pipelines, 143,191 manholes and 108,206 catchpits.

Within the Waitematā Harbour CRE, there are 2,204 km of reticulated pipelines, 58,403

manholes and 15,896 catchpits (the majority of which are operated by Auckland Transport).

The extent and age of reticulated stormwater system varies from sub-catchment to sub-

catchment, with the CBD being among the oldest and most intensely piped. The approach to

drainage management varies across the region with some of the oldest systems functioning as

combined lines that serve both wastewater and stormwater in one common pipe. New

drainage systems are separate systems.

5.3.2.15.3.2.15.3.2.15.3.2.1 Key Asset Management IssuesKey Asset Management IssuesKey Asset Management IssuesKey Asset Management Issues

As Auckland’s most developed CRE, there are a significant number of stormwater assets

(including natural assets) and their effective management, renewal and upgrading are essential

to ensure on-going performance to meet community and environmental objectives. Quality

control of asset installation also forms a key part of this. The following issues have been

identified relating to asset management and renewals:

1. Developing hard assets/structures in streams as a first response to erosion and other

management issues will continue to degrade stream health.

2. Asset information (completeness and quality) is highly variable, with limited information

on streams, and in some areas coastal structures, and age and condition of public pipe

networks. This includes:

a. The lack of asset information, particularly asset age, material and condition, and level

and accuracy of asset information affects critical asset management and renewals

strategy.

b. Lack of asset information also limits council’s ability to demonstrate resource consent

and permitted activity compliance.

c. Natural assets need to be better understood and quantified, and fully integrated into

asset management as an essential component of the stormwater system.

3. Quality control of asset installation is an additional issue for management.

5.3.35.3.35.3.35.3.3 FloodingFloodingFloodingFlooding

As mentioned under Section 5.3.2, the stormwater system consists of a number of natural and

built assets. When the reticulated drainage system (the primary system) is overwhelmed (or

where no reticulated stormwater system exists), overland flowpaths (the secondary system)

typically take the excess. Streams are an integral part of the stormwater system. In addition

to their significant environmental, amenity and cultural value, stream corridors (i.e. the main

stream plus the riparian margin) act as natural floodplains, conveying flood flows safely away

from properties. Within urban areas, roads also frequently act as overland flowpath routes.

Despite a formally-designed primary and secondary stormwater system, flooding of buildings

does occur (Figure 9). In addition, the amalgamation of the seven councils into the one

Auckland Council has resulted in a stormwater network designed to a number of different

standards with a wide range of flooding issues.

Flood hazard mapping has been conducted across the Waitematā Harbour CRE to various

levels of detail and completeness. The most current flood hazard maps cover the Auckland

Isthmus, North Shore and parts of Waitakere, while the oldest ones are in Rodney. To help fill

the gaps, Council conducted a more general rapid flood hazard assessment (RFHA) mapping

effort across the entire Auckland Council region. While RFHA method is less accurate than

Attachment A


sub-catchment-level stormwater modelling and flood mapping, it provides an indicative level

of detail on flood extents. In addition, Council has compiled the results of the sub-catchment-

level modelling with the RFHA results into one GIS layer for the 100 year ARI flood event (as

shown in Figure 8). Council has commissioned various engineering firms to update flood

hazard maps for a number of sub-catchments across the region. Sub-catchments presently

being modelled, remapped or with recently completed models within the Waitematā Harbour

CRE include Swanson/ Lincoln, Opanuku, Oratia, Whau, Oakley, Meola, Motions, the CBD,

Kohimarama, and Epsom/ Newmarket.

According to the Auckland Council Stormwater Asset Management Plan (AMP) (July 2012 –

2023) flooded floor count map, there are approximately 3,200 flooded floors in the

Waitematā Harbour CRE during a 100 year Average Recurrence Interval (ARI) storm event.

This amount represents 41% of the approximate 7,850 total number of flooded floors across

the Auckland region. While the numbers in the AMP need updating, they do demonstrate the

relative scale of flood issues in the region (Table 3). A number of habitable floors are also at

risk of flooding due to overland flows. Little specific information on this topic exists outside of

the former North Shore City Council area. An estimate of this risk has been made, but it is not

in wide use as the data is subject to interpretation and the topic needs further investigation.

The numbers presented in Table 4 are estimates and are provided herein only for comparison

purposes as the actual number needs to be more thoroughly investigated.

Consistently, flood protection has been the major driver in stormwater management across

the region over the years. Three issues relating to flooding have been identified, namely:

1. There is widespread flooding of habitable floors across the Waitematā Harbour CRE.

Overland flow paths also pose a threat to habitable floors across the region. The

number of predicted flooded floors in the Waitematā Harbour CRE comprises

approximately 41% of the flooding in the Auckland region.

2. Infill development has proven to be a major threat to overland flow paths, often

blocking flow paths and causing flooding.

3. Flooding of critical infrastructure (hospitals, power substations, emergency roadways,

etc.) needs to be better identified and quantified, and requires protection from

flooding for up to the 200 year rainfall event.

5.3.45.3.45.3.45.3.4 WaitematWaitematWaitematWaitematā Harbour CRE: Harbour CRE: Harbour CRE: Harbour CRE: StreamsStreamsStreamsStreams

Streams are the natural drainage pathways for stormwater runoff, and are therefore an

important component of the Auckland’s drainage system. Many urban streams were piped,

straightened, lined and otherwise modified during the development of Auckland to maximise

landuse, and manage flooding and erosion (particularly in older parts of Auckland). Overall,

the Waitematā Harbour CRE is estimated to contain between 800 and 1100 km of open

streams (Figure 10). Approximately 320 km are inside the Metropolitan Urban Limit, with the

remainder predominantly running through rural or forested areas. The only significant

“natural” lake in the catchment is Western Springs, which was substantially modified during

urban development.

Urban streams in the Waitematā Harbour CRE are subject to a range of interacting stressors,

whose combined effects leads to relatively predictable set of habitat and biological responses:

• the piping and realignment of streams has reduced the overall extent of stream

habitat;

• artificial linings disconnect reaches in many streams from the groundwater system;

• poorly designed and/or installed culverts, weirs, and other in-stream structures impede

the upstream migration of freshwater fish;

Attachment A


• urban streams tend to have more frequent, larger and flashier flood flows, and as a

consequence, stream bank erosion is a problem in many areas. Engineered channel

armouring is often required to protect stream banks, further reducing the extent of

natural stream channel;

• impervious cover can reduce groundwater recharge and affect stream base flows;

• elevated stream temperatures are likely to be harmful to temperature sensitive

invertebrates and fish. Elevated temperatures can be caused by:

o the lack of shading by riparian vegetation;

o the discharge of warm water from hot impervious surfaces and stormwater

detention ponds, and

o reduced base flows from the diversion of water.

• contaminants often exceed guideline values, and are expected to negatively affect

freshwater communities.

The general consistency of effects on urban streams is internationally recognised as the “urban

stream syndrome”. Measures can be taken to reduce the effects on streams in modern

greenfield developments, but urbanisation is still likely to reduce the extent of stream habitat,

and diminish ecological opportunity and function.

Not withstanding this, urban streams can:

• enhance urban landscapes and make them more liveable for city-dwellers;

• provide natural trails that link locations, facilities and communities;

• bring people together and promote sustainability through participation in

environmental programmes;

• enhance recreational experiences;

• play a role in maintaining ecosystem goods and services that streams can provide (for

example potential tourism, amenity, flood management and provision of supplies such

as food or medicine);

• reflect cultural and heritage values.

The Council has a significant role to play in maintaining and enhancing these values, and

outcomes can be optimised by directing effort at streams with the greatest potential to

produce substantial environmental and/or community benefits.

The characteristics and values of the Waitematā Harbour CRE urban streams vary markedly

from one stream to the next, depending on their history, surrounding landuse, and community

interest in their protection and enhancement. The following key issues have been identified

relating to streams:

1. Nearly all urban streams have been physically modified, and all have reduced ecological

values resulting from effects such as:

• accelerated stream channel erosion;

• vegetation removal;

• barriers to fish passage;

• piping, lining and straightening;

Attachment A


• contaminants (temperature, pH, metals, sediments); and

• Aquatic weeds.

There is nonetheless the capacity to improve ecological outcomes for freshwater

macro-invertebrate, fish and terrestrial species.

2. Streams continue to form an essential component of the stormwater system.

3. Polluted and physically unpleasant urban streams diminish landscape and amenity

values, and discourage the utilisation of public open space.

4. Attractive urban streams enhance landscape, aesthetic, amenity and property values.

They enhance recreational experiences, and provide natural trails which link locations,

facilities and communities. They bring people together and promote sustainability

through participation in environmental programmes. However, the potential of many

urban streams within the Waitematā Harbour CRE has not been realised.

5. Rivers and streams are of cultural significance to Māori, with their protection vital for

the mauri (life giving force) of the waters.

Based on the above, the potential of many urban streams within the Waitematā has not yet

been realised.

5.3.55.3.55.3.55.3.5 GroundwaterGroundwaterGroundwaterGroundwater

Stormwater is discharged to groundwater in basalt sections of the Auckland volcanic field

(Figure 11), and in these areas, ground soakage is used as a primary method of stormwater

disposal. The aquifers underlie approximately 40% of the central urban area. Stormwater is

collected and discharged into privately and publically owned soakage pits or wells, and large

soakage tunnels operated by the Council in some areas. Stormwater is generally discharged

into the soil or unsaturated zone and percolates through the fractures of the unsaturated

aquifer to the saturated zone. Groundwater then flows to the coast along ancient, lava-filled

valleys in the underlying Waitematā Group.

The basalt groundwater aquifers are extensively utilised for stormwater disposal, with private

soakage accounting for more than 50% of soakage volume. Three issues have been identified

relating to groundwater:

1. Stormwater discharges can have an adverse effect on the capacity and quality of

groundwater aquifers, although groundwater quality currently meets drinking water

standards in most urban aquifers.

2. Our knowledge of the chronic effects of stormwater soakage on the aquifer is limited,

particularly in respect of loss of aquifer capacity/sediment build up.

3. Without soakage, a reduction in stream baseflows can be expected, especially in areas

with high imperviousness.

5.3.65.3.65.3.65.3.6 Estuaries and the Estuaries and the Estuaries and the Estuaries and the HarbourHarbourHarbourHarbour

The Waitematā Harbour is a largely, intertidal drowned valley, with a complex shoreline of

sheltered inlets and tidal creeks. The main features of the Harbour are:

Attachment A


• A constricted entrance that runs from North Head to west of the Harbour Bridge, and

a large central body with three major tributaries. These include the Upper Waitematā

Harbour, Henderson Creek and Whau River.

• Five large tributaries and several minor tributaries also feed into the Upper Harbour.

The large tributaries include: Hellyers Creek, Lucas Creek, Paremoremo Creek,

Rangitopuni Creek, Brigham Creek and Waiarohia Inlet.

• Waterview Inlet is also a conspicuous feature of the central harbour. This consists of a

large embayment on the southern shore.

• Hobson Bay and Shoal Bay are significant features of the harbour entrance. Sheltered,

muddy shorelines along these tributaries are generally lined with mangroves, which

form broad forests in a number of enclosed embayments and tidal creeks.

• Pollen and Traherne Islands, and their surrounding shellbanks, are particularly

important high tide roosts for international migratory and endemic New Zealand

wading birds, and a variety of other coastal birds.

The southern Waitematā Harbour, together with the Manukau Harbour and Tamaki Estuary,

are national “hotspots” for coastal bird diversity and nationally vulnerable (threat code 3) bird

taxa. All three areas contain extensive sand and mudflats, which are a rich food resource for

shore birds. An approximately three hour tidal difference, and the narrow distances between

the Manukau Harbour and the Waitematā Harbour and Tamaki Estuary, also allow waders to

extend their feeding times by easily moving between the west and east coasts.

The Harbour also provides habitat for a variety of fish, including a range of culturally,

commercially and recreationally important species.

Waitematā Harbour has 11 coastal protection areas (CPAs) and 25 Cultural Heritage sites are

listed in Schedules 1 and 2 of the Auckland Regional Plan: Coastal. These are related to

historic structures (such as wharves, docks, lighthouses, buildings, factories, and seawalls),

landing, careening and portage sites, and hulks and shipwrecks.

The natural shoreline of the outer harbour has been radically altered during the course of

urban development, including breakwaters, reclamation, causeways, wharves and other uses.

New Zealand’s largest port, the Devonport Navy base and 4 marinas are located within the

Harbour. Ports and their access channel are occasionally dredged to maintain navigable

depths.

Sediments in several tributaries of the Waitematā Harbour are among the most contaminated

in the Auckland Region, with relatively high concentrations of copper, lead and zinc. The

health of the harbour is routinely monitored through the State of the Environment monitoring

programme. This programme, along with modelling studies, suggests that:

Attachment A


• Highest concentrations of metals are present in sediments from sheltered, muddy

estuarine sites on the southern shore of the Waitematā between Cox’s Bay and

Henderson Creek (Figure 12).

• Sediments in the main body of the harbour are relatively clean, but concentrations of

copper and lead are slightly elevated in some parts of the upper Waitematā Harbour.

• Contaminant levels are relatively low in Hobson Bay and Shoal Bay, but some sites have

elevated levels of copper, lead and/or zinc.

• Polycyclic aromatic hydrocarbons (PAHs - contaminants caused by the incomplete

burning of coal, oil and tar) are high at the outlets of Meola and Motions creek and next

to the Chelsea sugar factory. Levels of PAHs are also elevated at the outlet of

Newmarket stream in Hobson Bay.

• Contaminant concentrations from organic pesticides (e.g. DDT or Dieldren) are

generally low, but slightly elevated in Henderson Creek and at the outlet of Meola Creek.

• Mercury concentrations are found to be slightly elevated at three sites in Whau River, at

the Paremoremo Inlet, and at the outlets to Motions and Meola Creeks.

• Dispersal patterns have a broad scale influence on zinc concentrations in the harbour.

Those sub-catchments with the largest contribution through dispersal include

Henderson, Oakley, Whau and Lucas Creeks (Figure 13).

• Rural sub-catchments of the Upper Waitematā Harbour have the greatest effect on

over-all water quality in terms of suspended solids, nutrients, and faecal coliforms in the

Waitematā Harbour CRE, and wastewater inputs from some urban sub-catchments are

also affecting water quality (Figure 14).

• Benthic health is adversely affected by contaminants (i.e. the health of those animals

living within the bottom layer of an estuary). The worst benthic health rankings were

obtained in the Whau River, upper Henderson Creek and at the outlets of Oakley, Meola,

Motions and Coxs Creeks (see Figure 15).

The sources of the contamination are manifold, and include:

• Stormwater runoff from urban areas, with high concentrations found in older parts of the city (zinc is typically associated with run-off from galvanised roofing, as is copper. Copper is also associated with traffic, as are PAHs. Lead is a legacy issue from lead based petrol).

• Closed landfills, with many contaminant hotspots found in their vicinity. This includes

various areas along the southern Waitematā such as Meola, Henderson and Motions Creeks as well as the Newmarket Stream outlet at Hobson Bay.

• Direct inputs from commercial and industrial areas

• Discharges from marinas

Attachment A


Contributions of each of these sources will vary between sub-catchments and, at this stage, is not well quantified.

The effects of stormwater on the Waitematā estuaries and Harbour are related to discharges

of chemical contaminants, sediment, litter, and consequential impacts on ecological values.

Five issues have been identified with respect to effects on the Waitematā Harbour:

1. The southern estuaries of the Waitematā Harbour have high contaminant (metals –

zinc and copper) concentration levels and there is a high risk of increasing

contamination in the future.

2. The northern estuaries have low concentrations of metals at the moment, but Lucas

and Hellyers Creek are at risk of increasing contamination in the future to beyond

guideline levels.

3. Sediment and nutrients are mainly rural landuse issues. Consequently, their effects are

most evident in the Upper Waitematā Harbour.

4. Litter is a widespread issue, and the relative contribution of the stormwater system has

not been determined.

5. There are gaps in our knowledge of the direct contributions that activities such as

marinas, landfills and industry make to harbour contamination.

5.3.75.3.75.3.75.3.7 Stormwater Effects on the Wastewater NetworkStormwater Effects on the Wastewater NetworkStormwater Effects on the Wastewater NetworkStormwater Effects on the Wastewater Network

The older parts of the city are served by a combined stormwater and wastewater system,

which is operated by Watercare Services Ltd (and therefore, not covered by this consent

application). In that system, wastewater and stormwater are carried within the same pipe. In

dry weather, wastewater is conveyed to the Mangere Wastewater Treatment Plant. Similarly,

in light rain both wastewater and stormwater are conveyed to the treatment plant. However,

during heavy rain more stormwater is generated than the wastewater section can convey, and

a mix of stormwater and wastewater is discharged onto roads, or directly to streams and the

coast. Overall there are approximately 300 km of combined pipes remaining in the city. Major

contaminants in domestic wastewater are suspended solids, nutrients, organic materials,

bacteria and pathogenic microorganisms. Wastewater from commercial premises and

industries may additionally contain substances such as oils, grease, fats, metals, solvents and

other chemicals. Newer wastewater networks are separated from the stormwater system, and

therefore less susceptible to overflows (i.e. as a result of from blockages and other operational

matters).

The effect of stormwater on the wastewater network is a key issue where the two systems

operate as a combined network. Three key issues have been identified.

1. In areas of the Waitematā Harbour CRE, particularly where there is a combined

stormwater-wastewater network, flood waters are contaminated with wastewater.

This contaminated flooding can cause a public health risk, especially in areas with high

contact recreation.

2. Some combined sewer overflows operate in excess of 100 times per annum and

discharge on average 3,500,000m3 of wastewater contaminated stormwater our

streams each year. This has a damaging effect on the receiving environment and

creates a public health risk for contact recreation in freshwaters and at bathing

beaches in the Waitematā Harbour.

3. The primary issue is the extent to which this is a stormwater issue (as opposed to

solely the responsibility of Watercare) and, if it is a stormwater issue, how priorities

would be determined through a management response.

Wastewater is typically managed by Watercare Services Ltd, so a coordinated effort between

the Stormwater Unit and Watercare will be required to resolve stormwater effects on the

wastewater network.

A number of different criteria can be used to prioritise our efforts in resolving or managing

flooding issues. These relate primarily to whether Council focusses on regular nuisance

flooding of buildings or large, infrequent events which can compromise critical infrastructure.

The following criteria could be used to prioritise flooding issues:

1.1.1.1. Flooding occurrenceFlooding occurrenceFlooding occurrenceFlooding occurrence/ Frequency of flooding / Frequency of flooding / Frequency of flooding / Frequency of flooding : : : :

Flood solutions need to be identified in priority catchments and included in the forward works

programme. These could be identified by placing emphasis on recurrent flood problem areas

and flooding of buildings and critical infrastructure which occurs more frequently than the 10

year average recurrence interval (ARI) event. This would have to form part of a risk based

approach to resolving flooding issues.

2.2.2.2. Existing flooding and damage:Existing flooding and damage:Existing flooding and damage:Existing flooding and damage:

Priorities for flood solutions can also be identified based on damage to buildings and

infrastructure. A risk based approach would be taken whereby critical infrastructure and

emergency facilities would have the highest priority.

3.3.3.3. Cost to manage flooding issues:Cost to manage flooding issues:Cost to manage flooding issues:Cost to manage flooding issues:

Priorities to manage flood issues can be identified using cost as an indicator. Those flooding

problems that can be easily remedied, and at a low cost, would be a higher priority than those

which are expensive to remedy and have a low cost-benefit ratio.

4.4.4.4. Redevelopment opportunities:Redevelopment opportunities:Redevelopment opportunities:Redevelopment opportunities:

Flood management is undertaken in those areas earmarked for growth and in catchments

where there are a high level of complaints, predicted and actual flooding.

5.5.5.5. Multiple benefitsMultiple benefitsMultiple benefitsMultiple benefits of flooding projectsof flooding projectsof flooding projectsof flooding projects::::

Those projects which support multiple outcomes in terms of enhancing amenity, cultural and

recreational values should drive the prioritisation process. Areas where amenity, recreational

and cultural values can be enhanced through flood management initiatives should be

prioritised.

6.46.46.46.4 Urban Stream ManagementUrban Stream ManagementUrban Stream ManagementUrban Stream Management

A number of different criteria can be used to prioritise our efforts in urban stream

management. These relate to protecting high value areas for biodiversity outcomes,

recognising the value that all urban streams play in maintaining ecosystem goods and services

that streams provide, or creating functional habitat and amenity value. Criteria also include

practical considerations such as land ownership and timing.

Attachment A


1.1.1.1. Ease of iEase of iEase of iEase of interventionnterventionnterventionntervention::::

The ability to influence stream management and values depend on factors such as zoning,

ownership and access. Those streams which are zoned as open space and are within public

ownership can be more easily managed by the Stormwater Unit than those under private

ownership.

2.2.2.2. Existing ecological valuesExisting ecological valuesExisting ecological valuesExisting ecological values::::

All urban streams are impacted to some degree, but remaining ecological values still vary from

stream to stream. A few high-value reaches remain in bush-clad upper catchments or on the

urban margin. Shaded urban streams with natural beds maintain fish and reduced invertebrate

values, while concrete lined or piped “drains” provide little ecological function. Prioritisation

criteria could be to protect and enhance streams of great potential for ecological value.

3.3.3.3. The level of active community supportThe level of active community supportThe level of active community supportThe level of active community support::::

Community involvement in stream management is vital. Focusing on those areas where there

is a high level of community support will assist in ensuring the long term success of stream

Stream outcomes can be greatly improved if several projects can be combined. For instance,

benefits of remediating stormwater issues are much greater if it is done in association with

park upgrades, the installation of cycleways and other public facilities, wastewater upgrades or

other projects.

5.5.5.5. Cultural significanceCultural significanceCultural significanceCultural significance

All streams have cultural significance to local iwi due to the mauri of the waters, and many

have important historical significance. These values should be protected through stream

restoration and reduction of contaminants to the waters. This will also result in enhancing

cultural and historical understanding for the area.

6.6.6.6. Landscape integration and enhancementLandscape integration and enhancementLandscape integration and enhancementLandscape integration and enhancement

Attractive, healthy looking streams enhance urban landscapes. Stream corridors link

communities and bring nature to the city. They provide natural pathways for commuters,

exercise and passive recreation. They can provide a focal point for community interaction.

6.56.56.56.5 EsEsEsEstuaries and the Harbourtuaries and the Harbourtuaries and the Harbourtuaries and the Harbour

A key question surrounding the prioritisation of contaminant effects on estuaries and the

harbour is whether or not efforts should concentrate on highly contaminated areas or healthy

estuarine/ harbour areas.

Attachment A


1.1.1.1. Existing contaminantExisting contaminantExisting contaminantExisting contaminant levels levels levels levels

Available data shows that existing levels of contamination vary widely around Waitematā

Harbour. In general, tidal creeks and embayments on the southern side of the harbour are

more contaminated than those on the northern side of the harbour. Central parts of the

harbour are relatively clean. A priority could be to ensure that already highly contaminated

areas are not further degraded.

2.2.2.2. Actual tActual tActual tActual trends in contamination: rends in contamination: rends in contamination: rends in contamination:

Predicted and measured trends in heavy metal concentrations vary around the harbour.

Models predict that copper and zinc concentrations will slowly increase in central harbour

areas and rapidly increase in many tidal creeks. However, actual trends have been more

variable. Despite the uncertainties in trend prediction, areas of highest predicted change could

be used as a criteria for prioritisation (it provides an indication of potential change in the

receiving environment).

3.3.3.3. Contaminant loads and dispersal: Contaminant loads and dispersal: Contaminant loads and dispersal: Contaminant loads and dispersal:

The environmental “footprint” of individual catchments varies widely because of differences in

their contaminant loads and dispersal patterns in the coastal environment. Prioritisation could

be based on catchments that have the most widespread influence on the water quality of the

harbour.

4.4.4.4. Marine ecology: Marine ecology: Marine ecology: Marine ecology:

Ecological responses to contamination are key environmental endpoints. The health of

benthic communities is monitored by Council and used to assess contaminant effects. Benthic

health in the harbour ranges from good to highly degraded. Highest priority could be given to

areas with the poorest health ranking.

5.5.5.5. Amenity, aesthetics and useAmenity, aesthetics and useAmenity, aesthetics and useAmenity, aesthetics and use

Amenity, aesthetic and use values vary around the harbour. Stormwater contaminants,

especially litter and sediment, can degrade those values. Note that the effects of wastewater

pollution are not covered by this consent application. Areas of contact recreation could be

prioritised jointly with Watercare Services Ltd.

6.6.6.6. Cultural significanceCultural significanceCultural significanceCultural significance

The harbour and its water are of cultural importance to many iwi in the region, with many

areas having historical significance. These areas should be protected and enhanced to protect

the mauri of the waters, as well as enhance cultural and historical understanding of the

rock matrix. Improved treatment of stormwater prior to disposal into soakage systems is

undertaken progressively and targeted in areas of highest potential for sedimentation and

clogging.

Wastewater does not contribute to stormwater priorities. Wastewater overflows are managed

by Watercare Services Ltd, so a coordinated effort between the Stormwater Unit and

Watercare will be required to resolve contaminated flooding issues. Opportunities to

implement solutions will need to be identified in coordination with Watercare Services Ltd as

they arise.

4.4.4.4. Mauri of water:Mauri of water:Mauri of water:Mauri of water:

Mauri (life giving principle) can be used as an indicator of stream health, since the mixing of

waters from two different sources or water that contains contaminants, can negatively affect

the productivity of waters. Contaminated flooding and wastewater can degrade the mauri of

The purpose of this document has been to:

1. explain the consultation process for this application,

2. provide an explanation of the Auckland Council Stormwater Unit and its function, and

3. provide a summary of the Waitematā Harbour CRE NDC application.

The Stormwater Unit is aware that stakeholders with an interest in the Waitematā Harbour

CRE have already been extensively consulted at a high-level for strategic planning documents

such as the Auckland Plan, and the past consultative effort, with respect to stormwater

management, has informed the development of the application documents. As a result, the

Unit will attempt to avoid consulting on issues which have already been consulted on.

The Waitematā Harbour NDC Consultation Process is therefore focusing on two specific

questions for consultation:

Waitematā Harbour Stormwater Network Discharge Consent: FAQs 02-2013 ii

Introduction: This is your chance to assist Auckland Council’s Stormwater Unit in establishing priorities for stormwater management through the Waitematā Harbour stormwater network discharge consent (NDC) process. In te reo, Waitematā means sparkling waters, and the harbour and the streams that feed into it all have significant cultural value to the various iwi and hapu that have made it their home for hundreds of years. That spiritual connection is a reflection of the vital role that this special place has in all our lives. However, increasing levels of human activity around the harbour have degraded its environment and caused stream erosion and flooding problems. Contaminants (pollution) in the form of excess sediment, metals (such as zinc and copper), oils and litter have been washed into the harbour via the urban stormwater system and our streams. Careful management of land based activities, such as development through good land use practices, can help prevent this harm. The Stormwater Unit is committed to the Auckland Plan vision to become the world’s most liveable city. To be a liveable city we need to achieve a “water sensitive community”. The Stormwater Unit key objectives of safe communities, supporting growth, and healthy and connected waterways are leading into a water sensitive community. Key functions of the Stormwater Unit are to manage 5,900km of pipe network, 10,000 km of streams, and to look after assets worth over $2.5 billion. The Auckland Council Stormwater Unit would like you to provide feedback to confirm which of the following stormwater issues around the Waitematā Harbour are the highest priorities:







• stormwater effects on the wastewater network. You will also be asked to provide your views on the criteria that guide how, through this NDC process, Auckland Council selects its priorities for stormwater management in the Waitematā Harbour and its associated sub-catchments (i.e. stream catchment areas). This feedback will provide important information for the Waitematā Harbour stormwater NDC, a resource consent that will allow Auckland Council to continue discharging stormwater into the Waitematā Harbour and its contributing streams. Your feedback will assist in setting out the requirements and priorities for stormwater management around this important environment. These “Frequently Asked Questions” have been designed to assist you in understanding the process we are going through, and should be read in conjunction with the other consultation material which has been prepared (see “Further Information”).

Waitematā Harbour Stormwater Network Discharge Consent: FAQs 02-2013 iv

Glossary of Terms Consolidated receiving environment: A consolidated receiving environment (CRE) describes the area of land draining to a distinct marine receiving environment or coastal catchment. For example, the Waitematā CRE drains to the Waitematā Harbour (See frequently asked question 15). Impervious Surface: means surfaces constructed of materials which are resistant to water or other fluid passing through them. Levels of Service: Levels of Service are measurable performance indicators and targets, describing how managing stormwater contributes to the delivery of the strategic goals of the organisation and how social, economic, environmental and cultural outcomes identified by the community are supported. Network discharge consent: A stormwater network discharge consent is applied for under the Resource Management Act (1991) and the Auckland Regional Plans Air, Land and Water and Coastal. It is a consent that authorises the diversion and discharge of stormwater, including associated contaminants, from existing and potential future public stormwater networks within urban areas and rural and coastal settlements. Riparian: The Auckland Plan (2012) defines riparian as the strip of land identified along the edges of natural watercourses. Sensitive Receiving Environment: With respect to stormwater, any land, or marine or fresh water body with significant social, cultural and environmental values which are susceptible to adverse effects of stormwater contaminants and flows. Stormwater: Stormwater is rainwater that flows over land (buildings, roads, etc) into drains, along waterways, eventually discharging at the coast and includes the pollutants that are picked up along the way. In urban areas, rain that falls onto roofs, roads and other hard surfaces collects in stormwater catchpits and is carried through a system of pipes to our receiving waters. These pipes have been built to protect public safety by directing water away from houses and people and to prevent flooding. Stormwater Network: The stormwater network consists of natural assets (including streams, ground aquifers and overland flow paths) and built infrastructure assets (including pipes, detention and treatment devices, outfalls, culverts and channels), which carry and manage stormwater before it is discharged to the receiving environment. Sub-catchment: A sub-catchment refers to the stream (freshwater) catchment areas which drain into a marine area. There are a number of sub-catchments within one consolidated receiving environment. Wastewater: Another term for wastewater is sewage. Sewage refers to the liquid wastes of a community, which may contain toilet wastes, sullage, trade wastes and stormwater infiltration (Auckland Regional Policy Statement, 1999).

1. What is the purpose of this consultation process?

This is your chance to help establish priorities for stormwater management in the Waitematā consolidated receiving environment (i.e. the area of land draining to a coastal receiving environment, such as the Waitematā Harbour). In te reo, Waitematā means sparkling waters, and the harbour and the streams that feed into it all have significant cultural value to the various iwi and hapu, and the Auckland community as a whole, that have made it their home for hundreds of years. The spiritual connection that we have is a reflection of the vital role that this special place has in all our lives. However, increasing levels of human activity around the harbour have degraded its environment and caused stream erosion and flooding problems. Contaminants (pollution) in the form of excess sediment, oils, chemicals and litter have been washed into the harbour via the urban stormwater system. Careful management of land based activities, such as development through good land use practices and management of stormwater, can help prevent this harm. The Auckland Council Stormwater Unit would like you to provide feedback and input into which of the following stormwater issues around the Waitematā Harbour are the highest priorities:-







• stormwater effects on the wastewater network. You will also be asked to provide your views on the criteria that guide how, through this NDC process, Auckland Council selects its priorities for stormwater management in the Waitematā Harbour and its associated sub-catchments (i.e. stream catchment areas). This feedback will provide important information for the Waitematā Harbour stormwater NDC, a resource consent that will allow Auckland Council to continue discharging stormwater into the Waitematā Harbour and its contributing streams. Your feedback will assist in setting out the requirements and priorities for stormwater management around this important environment. These “Frequently Asked Questions” will assist you in understanding the consultation process for this project, as well as different aspects of the network discharge consent process in relation to stormwater management.

2. Haven’t Auckland Council already asked us this before?

Feedback that has already been provided through previous consultation on the Auckland Plan and the Unitary Plan will be referenced, but this consultation is more focussed on the key task of getting the right balance between the various stormwater priorities. Some of you will also have provided input to previous City and District council consent processes. However, under the Auckland Council we are seeking to identify issues and priorities across the legacy council areas that contribute to the Waitematā stormwater network consent process. Where possible, relevant feedback from this consultation will also be used for the Auckland Council’s consultation relating to Council’s implementation of the National Policy Statement: Freshwater – which relates to stream catchments in detail, and to the Marine Spatial Plan -

3. What aspects of the consent application are you requesting feedback on?

The Waitematā Network Discharge Consent Consultation Process is focusing on two specific questions for consultation:

1. From the stormwater issues identified, what do you think are the priorities for the Waitematā Harbour CRE and what must be most urgently addressed?

2. From the Stormwater Unit’s responsibilities, what do you think are the criteria that

council should use for selecting stormwater management priorities? Specific information from the Waitematā Harbour stormwater network discharge consent application, which is relevant to these questions, is included in Section 5 and 6 of the “Consultation Summary Document”. This document can be found on Council’s website at: http://www.aucklandcouncil.govt.nz/haveyoursay

4. How can I provide feedback?

There are a number of different ways in which you can provide feedback:

• complete the consultation feedback form and post it to the relevant address, or

• contact us on [email protected]

5. Who should I contact for further information?

For further information please send an email to: [email protected] Alternatively contact Sue Ira on: 021 922 408

6. Where can I get a copy of the consultation information?

A copy of the relevant documentation pertaining to the Waitematā Harbour stormwater network discharge consent application is located on Council’s website at: http://www.aucklandcouncil.govt.nz/haveyoursay Alternatively, information can be viewed at the following Auckland Council local offices:

• Henderson

• Takapuna

• Orewa

• Graham Street, Auckland

• Hereford Street, Auckland

• Manukau

7. What happens to my feedback?

Feedback received from the consultation process will be summarised and will help to inform the setting of priorities for the network consent application. Based on priority issues and the selected criteria for prioritisation, a “best practicable option” approach to managing stormwater discharges from the public network will be developed (see frequently asked question 23).

8. Will the consultation be on-going after lodgement of the network consent

application?

Consultation through the Waitematā Harbour stormwater network discharge consent application process is just the first step. The Stormwater Unit is committed to building on-going and lasting relationships with its stakeholders. Consultation will be undertaken through the sub-catchment management planning process, and also at a project level. If you are interested in being part of this further consultation, please indicate this to us on the feedback form located on Council’s website at: http://www.aucklandcouncil.govt.nz/haveyoursay Consultation on other aspects of water management in the Auckland region will also provide you with the opportunity to have input on how the region’s water resources will be managed. These projects include implementation of the Nation Policy Statement for Freshwater Management http://www.mfe.govt.nz/rma/central/nps/freshwater-management.html and the New Zealand Coastal Policy Statement http://www.doc.govt.nz/publications/conservation/marine-and-coastal/new-zealand-coastal-policy-statement/new-zealand-coastal-policy-statement-2010/ which includes marine spatial planning.

9. What is stormwater?

Stormwater is rainwater that flows over land (buildings, roads, etc.) into drains, along waterways, eventually discharging at the coast. In urban areas, rain that falls onto roofs, roads and other hard surfaces collects in stormwater catchpits and is carried through a system of pipes to our receiving waters. These pipes have been built to protect public safety by directing water away from houses and people and to prevent flooding. However, as land changes from bush or farmland to hard urban (impervious) surfaces, the amount of water running off the land increases and the amount of water soaking into the ground decreases. This increased quantity of water can cause problems downstream. In addition, as stormwater runs over impervious surfaces it picks up contaminants such as sediment, hydrocarbons and trace metals such as zinc, copper and lead which can then affect the quality of our streams and harbours.

10. What are the effects of stormwater?

The three key adverse effects of urban stormwater on the environment are:

Attachment B


Water quantity effects Large areas of impervious surface cause increases in stormwater run-off, and this increases the risk of flooding and erosion. Developments which are too close to existing watercourses, or located in areas where flood waters flow or pond, are particularly susceptible to flood risks. Water quality effects Impervious surfaces contain pollutants derived from our everyday urban life. This could be anything from litter, dust, decomposing vegetation and sediment to zinc, copper and lead from building materials, and oils and exhaust emission particles from motor vehicles. These everyday pollutants can affect water quality in our streams and harbours and be deposited and build up in sediments. In addition, wastewater overflows into the stormwater system or streams can cause public health and environmental effects. Aquatic habitat and ecological effects Increased stormwater flows cause erosion and sedimentation of streams, and contamination of stormwater run-off causes a deterioration of the quality of water entering receiving environments. This altered hydrology (i.e. increased stormwater flows) and contamination of stormwater may then cause a loss of freshwater aquatic resources and degrade riparian areas. A build-up of contaminants in estuary and harbour areas can also affect benthic (sea bed) organisms such as crabs and shellfish. Many of these adverse effects are already occurring. While continued growth and redevelopment have the potential to increase existing effects, they also offer an opportunity to reduce existing effects through better land use practices and improved stormwater management. In addition, the stormwater network discharge consents provide us with an opportunity to create a framework for managing and mitigating these identified existing effects to Auckland’s stream and coastal environment, and its public stormwater network.

11. Why do we need to manage stormwater?

Stormwater drainage is a natural process in which rainwater flows by gravity across or through the ground to groundwater, formal drains, streams, lakes, wetlands and ultimately to the coast. Urbanisation modifies this natural process. As a city develops the area covered by impervious surfaces (i.e. surfaces which do not allow rainfall to infiltrate the earth, such as roads and roofs) also grows. Importantly, impervious surfaces also make the water runoff faster so that in heavy rainfall, flows can be significantly larger than natural flows. This increases the potential for flooding and erosion. Urban streams are often piped, lined and channelized during development to efficiently convey stormwater runoff and minimise erosion. As a consequence, many areas lack a network of open stream channels and the extent of urban streams has been severely reduced, particularly in the central Auckland isthmus. Contaminants and sediment become entrained in stormwater as it flows from the land, and through natural and artificial drainage systems. The type and amount of chemical contaminants present in stormwater runoff varies in relation to the activities occurring in the catchment and contaminant management practices. The primary contaminants of concern in the Auckland Region are sediments, copper, zinc, lead and hydrocarbons. These

Attachment B


contaminants attach to sediment and organic particles, and are dispersed and accumulated in depositional areas in the coastal zone. The build-up of contaminants in sediments can be toxic to aquatic life. If not effectively managed, the effects listed above can increase. This, in turn, increases the risk to our communities and natural environments. Effective management of stormwater involves minimising its generation and then conveying, managing and discharging runoff in a way that minimises potential adverse effects.

12. Who is responsible for managing stormwater?

Auckland Council’s Stormwater Unit (“the Unit”) manages a network of natural assets and approximately $2.5 billion worth of built infrastructure (including pipes, detention and treatment devices, outfalls, culverts and channels), and also leads best practice stormwater management advice for Auckland Council. The Unit is responsible for the operation of this regional stormwater network and managing its effects, as outlined in the 2010 amendment of the Local Government Act 2002. This includes the operation, maintenance and management of the region’s public stormwater infrastructure and natural assets on public land. Other entities also manage stormwater assets:

• Assets located in parks and reserves are jointly maintained by the Stormwater Unit and the Parks, Sports and Recreation Department.

• Auckland Transport owns stormwater assets in road corridors and it has been agreed that the Stormwater Unit maintains these assets. This will help to ensure consistent maintenance practices and to optimise maintenance costs.

• Watercare Services Limited manages the combined sewer network (these are pipes which discharge both wastewater and stormwater, and are located in some parts of the city).

• A variety of private entities own and maintain stormwater assets, including stormwater reticulation and water quality devices. In addition, streams on private land are the management responsibility of property owners.

13. What is a stormwater network discharge consent?

The Auckland Council Stormwater Unit is required under the Resource Management Act (1991) to obtain resource consents to discharge stormwater (water and contaminants) from the region’s stormwater network into the natural environment. Under the Auckland Regional Plan: Air Land and Water and the Auckland Regional Plan: Coastal, stormwater discharge consents from the public stormwater network are called stormwater network discharge consents (NDCs). A stormwater NDC can authorise the following activities:

• diversion and discharge of stormwater from existing and potential future public networks in urban areas, and in rural and coastal settlements, and

• discharge of contaminants (those typically carried in stormwater runoff – not from industrial or other trade processes).

At present, objectives and policies relating to NDCs are set out in the Auckland Regional Plan: Air Land and Water, and the Auckland Regional Plan: Coastal. The figure below illustrates the relationship between NDCs, Council policies and statutory documents. In the future, stormwater NDCs will be required to meet the requirements of the Auckland Council’s Unitary Plan, which is currently being prepared.

Attachment B


14. Why does Auckland Council have to apply for a stormwater network discharge

consent?

The Auckland Council Stormwater Unit is required under the Resource Management Act (1991) to obtain resource consents to discharge stormwater (water and contaminants) from the region’s stormwater network into the natural environment. This authorisation of stormwater discharges from the public network is known as a stormwater network discharge consent under the Auckland Regional Plan: Air Land and Water and the Auckland Regional Plan: Coastal.

15. What area will this consent cover?

Auckland Council has designed a high level, broad-scale assessment approach to stormwater network discharge consents, focusing on outcomes for Consolidated Receiving Environments (CREs) (i.e. the area of land draining to a coastal receiving environment, such as the Waitematā Harbour). Ten CREs have been identified for the Auckland region (see map below). The current consultation process focuses on the first CRE to be considered: the Waitematā Harbour (circled in red). The Waitematā Harbour CRE priorities are important to the long term wellbeing and interests of a large number of people. Other NDCs will be progressed over the next 5-10 years.

Attachment B


16. How does this consent application affect me?

The Waitematā Harbour stormwater network discharge consent application covers a large area, both geographically and in terms of population. It includes the rohe of 17 iwi/hapu and the constituencies of 12 Local Boards and 20 Councillors. The issues and priorities under discussion – those of flooding of homes and businesses, erosion of streams, sedimentation of streams and estuaries, and contamination by pollutants of sensitive natural habitats, fish, shellfish, birdlife, marine mammals and other biota – are of interest and concern to a wide range of stakeholders. It is neither practically possible nor affordable to address all the negative effects of stormwater discharges, including existing effects within the next 35 years (the duration of a stormwater network consent). Effort and resources therefore need to be directed to where we can make the most difference, in accordance with identified priorities. The network consent is a strategic, high level consent and seeks to set a number of high level priorities for stormwater management. These priorities will be further investigated through a sub-catchment management planning programme, during which local issues will be identified and investigated.

17. Would the consent authorise stormwater discharges from my property?

If your property is in the Waitematā Harbour Consolidated Receiving Environment catchment area and discharges into the public network (and not directly into a stream, the coast or to ground soakage), then the stormwater runoff from your property will be included within the Auckland Council’s stormwater network discharge consent. The network discharge consent will not authorise, amongst other activities, private stormwater discharges that do not enter the public network, discharge of industry related contaminants from industrial premises and discharge of wastewater and associated contaminants.

Location of the Waitematā Harbour Consolidated Receiving Environment

Attachment B


The discharges from the Auckland Transport road network, including those where the stormwater is discharged via a dedicated road asset, are included. Stormwater discharges from the state highway network that enter Council’s stormwater network are also included in the network discharge consent. The Waitematā Harbour stormwater network discharge consent will cover stormwater discharges from future development, subject to consent requirements being met (see frequently asked question 19).

18. Are streams considered part of the public network?

Streams are an important part of the wider stormwater system. However, they are also a receiving environment in their own right. Our NDC will cover discharges into streams and, as a consequence, the mitigation of adverse effects on streams. However, the NDC does not grant any right or responsibility for stream management on Auckland Council. Streams which run through publicly owned land (such as parks and reserves) are managed by Auckland Council. Streams which run through private property are not managed by Auckland Council, and are the responsibility of the private landowner.

19. Will the consent authorise stormwater discharges from future development?

Council is applying for the following activities to form part of the network discharge consent:

• the diversion of surface water in urban areas, and coastal and rural settlements; and

• existing and future stormwater discharges from the Council’s stormwater network in urban areas, and coastal and rural settlements.

In this case, “future” stormwater discharges relate to infill development, major redevelopment and new greenfields development, subject to meeting established process and performance requirements.

20. What structures are included within the authorisation of the network?

The stormwater network resource consent application will not seek consent for construction, operation and maintenance activities in the marine environment or within streams, nor for existing structures (as these are generally permitted activities). New structures will be consented separately on an ‘as needed’ basis.

21. Does the consent authorise discharges or overflows from the wastewater

system?

The stormwater network resource consent application will not seek consent to discharge of wastewater and associated contaminants. Wastewater is managed by Watercare Services Ltd who is applying, through a separate network consent process, to authorise discharges and overflows from the wastewater system. However, the Stormwater Unit and Watercare will work together to seek integrated solutions where this is possible.

22. Will the consent be notified?

The Stormwater Unit is applying for a non-notified consent on the basis that:

• The Auckland Regional Plan: Air, Land and Water specifically provides for these consents to be non-notified;

• The NDC is essential infrastructure and stormwater discharges cannot be stopped;

Attachment B


• Consultation through the NDC is expected to be high-level, engaging and thorough, thereby delivering a transparent process and contributing to a high-quality consent application

• Consultation will be on-going with stakeholders, as the process moves down from the high-level consent to detailed catchment-based studies and then project-based consents; and

• Stakeholders have already been extensively and recently consulted for several other high level documents (see frequently asked question 2), as well as for the previous Council-led catchment-based work that makes up the area covered by this NDC.

However, the final decision on notification rests with the Regulatory Authority and Independent Commissioners.

23. What is “Best Practicable Option”?

Under Section 2 of the RMA, the best practicable option (BPO) is defined as: “BPO, in relation to a discharge of a contaminant or an emission of noise, means the best method for preventing or minimising the adverse effects on the environment having regard, among other things, to:

a) The nature of the discharge or emission and the sensitivity of the receiving environment to adverse effects; and

b) The financial implications, and the effects on the environment, of that option when compared with other options; and

c) The current state of technical knowledge and the likelihood that the option can be successfully applied.”

Policy 5.4.8 of the Auckland Regional Plan: Air Land and Water further explains BPO in the context of the types of matters that the regulatory authority will have regard to when assessing stormwater network discharge consents. This includes further matters such as the timeframe in which the adverse effects can be addressed, funding availability, the extent to which the network operator is responsible for or has control over the identified effects, and the benefits of maintaining and optimising existing infrastructure. Auckland Council is undertaking a four-tiered approach to planning, network discharge consenting and delivery. The diagram below shows the four levels together with the outputs from these levels that contribute to the best practicable option (BPO). While all four levels form part of the BPO, the network consent process comprises the first two stages. The second two stages are focussed on developing, optimising and delivering solutions and improvements. Regional Tier Level: Some stormwater management options are appropriately assessed implemented at the regional level. These options include land use planning and implementation (District, Regional and Unitary Plan), and region-wide initiatives. Network Consent Tier Level: The focus is primarily on identifying priority catchments and areas for more detailed investigation. Prioritisation will be undertaken as part of each network consent application, and will be specific to each consolidated receiving environment. This consultation forms part of this process. Sub-catchment Tier Level: The focus is on developing detailed solutions to the priority issues identified through the NDC and working at a local level to develop solutions that, where possible, are integrated with local initiatives to deliver multiple benefits.

Waitematā Harbour Stormwater Network Discharge Consent: Brochure & Feedback Form 02-13 1

Waitematā Harbour Stormwater Network Discharge Consent - Protecting our Waters Stormwater Priorities Consultation - Information Brochure and Request for Feedback

Introduction: This is your chance to assist Auckland Council’s Stormwater Unit in establishing priorities for stormwater management through the Waitematā Harbour stormwater network discharge consent process. In te reo, Waitematā means sparkling waters, and the harbour and the streams that feed into it all have significant cultural value to the various iwi and hapu, and the Auckland community as a whole, that have made it their home for hundreds of years. The spiritual connection that we have is a reflection of the vital role that this special place has in all our lives. However, increasing levels of human activity around the harbour have degraded its environment and caused stream erosion and flooding problems. Contaminants (pollution) in the form of excess sediment, metals (such as zinc and copper), oils and litter have been washed into the harbour via the urban stormwater system and our streams. Careful management of land based activities, such as development through good land use practices, can help decrease this harm. The Stormwater Unit is committed to the Auckland Plan vision to become the world’s most liveable city. To be a liveable city we need to achieve a “water sensitive community”. The Stormwater Unit key objectives of safe communities, supporting growth, and healthy and connected waterways are leading into a water sensitive community. Key functions of the Stormwater Unit are to manage 5,900km of pipe network, 10,000 km of streams, and to look after assets worth over $2.5 billion. The Auckland Council Stormwater Unit would like you to provide feedback and input into which of the following stormwater issues around the Waitematā Harbour are the highest priorities:

• managing growth, • managing infrastructure/ assets, • managing flooding (or the risk of flooding), • urban stream management, • contamination of the estuaries and harbour, • managing stormwater discharges to groundwater, and • stormwater effects on the wastewater network.

You will also be asked to provide your views on the criteria that guide how, through this network discharge consent process, Auckland Council selects its priorities for stormwater management in the Waitematā Harbour and its associated sub-catchments (i.e. stream catchment areas). This feedback will provide important information for the Waitematā Harbour stormwater network discharge consent, a resource consent that will allow Auckland Council to continue discharging stormwater into the Waitematā Harbour and its contributing streams. Your feedback will assist in setting out the requirements and priorities for stormwater management around this important environment.

What we want to know: 1. From the stormwater issues identified, what do you think are the priorities for the

Waitematā Harbour area and what must be most urgently addressed? 2. From the Stormwater Unit’s responsibilities, what do you think are the criteria that


What you need to know: Stormwater drainage is a natural process where rainwater flows by gravity across or through the ground to drains, streams, lakes, groundwater or wetlands and ultimately to the coast, or underground aquifers in some areas of Auckland. Urbanisation modifies this natural process. As a city develops the area covered by impervious surfaces also grows. This increases the quantity of water that runs off as surface flows, and the potential for flooding and erosion. Removal of streamside vegetation has also reduced the quality of urban streams. Many urban streams have previously been piped or lined with concrete during development to efficiently convey stormwater runoff and minimise erosion. As a result the extent of urban streams has been severely reduced and many areas lack a connected network of natural open stream channels, particularly in the central Auckland isthmus. Contaminants are picked up by stormwater as it travels across the land, and passes through natural and man-made drainage systems. The primary contaminants of concern in the Auckland region are sediment (soil particles), copper, zinc, lead and polycyclic aromatic hydrocarbons. These contaminants can be toxic to aquatic life, and cause harm as they are dispersed in the aquatic environment. The Auckland isthmus differs from the rest of Auckland in that a large proportion of the city is located on groundwater aquifers. These aquifers play an important role in stormwater disposal, as well as supplying some of Auckland’s drinking water. Many of these adverse effects are already occurring. The stormwater network discharge consents provide an opportunity to create a framework for managing and mitigating these identified effects to Auckland’s stream and coastal environment, and its public stormwater network. It is neither practically possible nor affordable to address all the negative effects of stormwater discharges, including existing effects, within the next 35 years (the duration of a stormwater network consent). Effort and resources therefore need to be directed to where we can make the most difference, in accordance with identified priorities.

Attachment C


How Consents are managed: At present, stormwater discharges from Council’s stormwater network are covered by a range of authorisations, which vary in their age and the activities they cover. This makes their management very complicated, difficult and costly, with inconsistencies across the region. With amalgamation into a single council, Auckland Council is endeavouring to manage stormwater consistently and efficiently. Auckland Council is committed to replacing these disparate authorisations with a more strategic approach to stormwater network discharge consents, concentrating on outcomes for Auckland’s coastal areas. The Auckland region has been divided into 10 areas, known technically as Consolidated Receiving Environments (CREs). This term describes the area of land draining to a coastal receiving environment, such as the Waitematā Harbour. The stormwater network discharge consent therefore relates to the land area and streams that drain water into the consolidated receiving environment. In future this strategic consent will accelerate the consenting project process in these areas, as well as set a benchmark for best-practice stormwater management in the area.

The first consolidated receiving environment to proceed is the Waitematā Harbour. The Waitematā Harbour priorities are important to the long term wellbeing and interests of a large number of people.

Location of the Waitematā Harbour Consolidated Receiving Environment

Attachment C


The Waitematā Harbour Consolidated Receiving Environment (CRE): The Waitematā Harbour CRE covers around 45,000ha and contains one of the earliest and most intensely urbanised areas in New Zealand. There are 54 sub-catchments, approximately 2,204km of reticulated pipelines, 58,403 manholes and 15,896 catchpits. There is an estimated 800km to 1100km of open streams which drain, via estuaries, to the Waitematā Harbour. The Waitematā stormwater network discharge consent application focusses on priorities within the urban areas of the Waitematā Harbour consolidated receiving environment.

How will the stormwater network discharge consents affect you? Consolidation of the numerous authorisations will assist Auckland Council and developers by simplifying management of the consent process. The stormwater network consents will set parameters around priorities for stormwater management, and guide sub-catchment (i.e. individual stream catchments within the greater consolidated receiving environment) planning initiatives. In addition, it will assist with directing Council as to where physical works will be undertaken to improve stormwater management. The type and scale of various development activities, which can take place around the Waitematā Harbour, will still be governed by the limitations already set in the existing (i.e. the district plans) and proposed planning documents (i.e. the Unitary Plan). What next? This consultation is the start of a long-running process to connect the people and communities around the Waitematā to our streams and harbour. Key to this process is the establishment of sustainable relationships between Auckland Council and our communities that are founded on a sense of trust, good communication and a mutual understanding of the various needs and priorities across the region.

Further Information: Auckland Council has published two further documents explaining consultation surrounding the Waitematā Harbour network discharge consent stormwater priorities:

• Frequently Asked Questions – including a list of detailed responses to the frequently asked questions about this project.

• The Waitematā Harbour Stormwater Network Discharge Consent Consultation Summary Report – a detailed technical report regarding the challenges of managing the stormwater draining into the Waitematā Harbour. This report contains details regarding key issues within the Waitematā Harbour CRE, along with an explanation of the potential criteria for prioritisation.

These documents are available at http://www.aucklandcouncil.govt.nz/haveyoursay, and more information on stormwater is available on the Auckland Council website’s stormwater pages www.aucklandcouncil.govt.nz/stormwater. Alternatively, please contact us on: [email protected] Definitions: Consolidated receiving environment: A consolidated receiving environment (CRE) describes the area of land draining to a distinct marine receiving environment or coastal catchment. For example, the Waitematā CRE drains to the Waitematā Harbour (for more information, please see frequently asked question 15). Levels of Service: Levels of Service are measurable performance indicators and targets, describing how managing stormwater contributes to the delivery of the strategic goals of the organisation and how social, economic, environmental and cultural outcomes identified by the community are supported. Impervious Surface: means surfaces constructed of materials which are resistant to water or other fluid passing through them. Network discharge consent: A stormwater network discharge consent is applied for under the Resource Management Act (1991) and the Auckland Regional Plans Air, Land and Water and Coastal. It is a consent that authorises the diversion and discharge of stormwater, including associated contaminants, from existing and potential future public stormwater networks within urban areas and rural and coastal settlements. Sensitive Receiving Environment: With respect to stormwater, any land, or marine or fresh water body with significant social, cultural and environmental values which are susceptible to adverse effects of stormwater contaminants and flows. Stormwater Network: The stormwater network consists of natural assets (including streams, ground aquifers and overland flow paths) and built infrastructure assets (including pipes, detention and treatment devices, outfalls, culverts and channels), which carry and manage stormwater before it is discharged to the receiving environment.
