Comments
Major
stormwater capital works projects
6. As stated in
the executive summary, overall expenditure on stormwater capital works is
tracking slightly ahead of schedule for 2015/2016, with expenditure of $52.9
million against a budget of $49.3 million up to 31 March 2016.
7. The full year
forecast remains within the approved budget in the Long-term Plan 2015-2025 of
$73.9 million and is on track for successful delivery.
8. A progress
update on five major stormwater capital works projects is provided below. This
describes project objectives, scope and key achievements during the update
period.
Wynyard
Quarter Stormwater Upgrades
9. The objective
of this project is to undertake flood alleviation works to reduce flooding of
commercial floors and frequent flooding of roads in the Wynyard Quarter at an
estimated capital cost of $10 million. The project also supports the proposed
further development of Wynyard Quarter.
10. The design and
construction flood alleviation works have been split into three discreet work
packages (or stages) to coincide with the proposed road upgrades and
development requirements of Auckland Transport and Panuku Development Auckland
respectively.
11. Individual
memorandums of understanding have been signed with Auckland Transport and
Panuku Development Auckland for the Stage One works and construction is
underway in the vicinity of Halsey Street and Madden Street.
12. The design of
the Stage Two works located at the north western end of Wynyard Quarter is
complete. The implementation of the works will be programmed to coincide with
Auckland Transport works and developments as they proceed.
13. The design of
the Stage Three works located at the south western end of Wynyard Quarter is
currently on hold until the implementation timings of the Stage Two works are
known.
14. Engagement with
mana whenua on the project is being undertaken by Auckland Transport as the lead
delivery agency.
Te Auaunga
Awa – Walmsley and Underwood Reserves Rehabilitation Project
15. The primary
objective of this project is to reduce risk of flooding and to provide for
growth in the Oakley stormwater catchment at an estimated capital cost of $24
million.
16. The project
involves stream widening and restoration of 1.3 kilometres of Te Auaunga Awa,
between Sandringham Road Extension and Richardson Road. The existing culverts
at Richardson Road and Beagle Avenue will be replaced with new road bridges to
improve conveyance of flood flows. A number of other assets will also be
provided through the project such as pedestrian bridges, cycleways and an
outdoor classroom.
17. The project will
enable provision of new housing through flood plain reduction. It will also
enhance social connectedness through providing additional walking and cycling
connections and improve the health of the awa (creek).
18. The design of
the project is complete and resource consent for the project was granted in
February 2016.
19. A report seeking
approval of the procurement plan for construction of the project will go to the
Tenders and Procurement Committee in May 2016. Construction works are
programmed to begin in January 2017.
20. Engagement
with mana whenua: Iwi were invited to engage from the inception of the
project. Five iwi indicated a desire to engage (Ngāti Tamaoho, Ngāti
Whātua Ōrakei, Ngāi Tai Ki Tāmaki, Te Kawerau a Maki and Te
Akitai Waiohua).
21. Representatives
of these iwi were included in the operational group for the project, which met
monthly, and were also involved in all design workshops. A mana whenua
representative was also selected by iwi to sit on the project steering group.
22. Feedback from
mana whenua was incorporated throughout the design process, leading to a number
of changes in the project scope. For example, the project was renamed Te
Auaunga Awa, more wetlands and swales were included in the design to improve
water quality, Māori artworks will be incorporated into the bridge and
other infrastructural elements, and traditional Māori games will be
recognised in the design of playgrounds.
23. Engagement with
mana whenua will be ongoing throughout the construction phase.
Ports of
Auckland Stormwater Upgrade Project
24. The objectives
of this project are to rehabilitate the existing stormwater culvert through
Ports of Auckland and to construct additional conveyance capacity to reduce
flood risk in the lower section of the catchment. The project has an estimated
capital cost of $25 to $35 million.
25. The scope of the
project includes construction of twin pipes from the rail corridor, across Quay
Street and through Ports of Auckland land to the sea. The project will replace
the existing stormwater pipeline and will address flooding in the lower
catchment to reduce the risk of flooding to Britomart Station.
26. The early
contractor involvement contract to develop the project was awarded to McConnell
Dowell. Preliminary design of the project is due to be complete in June 2016.
27. A draft contract
works offer will be received in September 2016 and, subject to successful
negotiations and approvals by the Tenders and Procurement Committee, a design
build contract is expected to be awarded in November 2016, with a start date in
the first half of 2017, subject to receiving the necessary consents.
28. Consultation
with stakeholders, including Ports of Auckland, Auckland Transport, KiwiRail
and iwi, is ongoing. A memorandum of understanding between the Ports of
Auckland and Auckland Council is being prepared.
29. Engagement
with mana whenua: Council has provided information about the project to all
iwi with an interest in this rohe. To date Ngāti Tamaoho, Ngāti
Paoa, Ngāi Tai ki Tāmaki, Ngāti Maru and Ngāti Whatua Ōrākei have attended either a site visit
or workshop on the project.
30. Key concerns
raised by mana whenua have included the potential for the project to improve
water quality in the project area. Improving water quality is challenging to
address through this project, given the focus on flooding reduction and
replacement of an existing pipeline,
31. However, this
feedback is being addressed through a separate review of contaminants of
concerns across the city centre catchment and treatment opportunities. This
will inform the development of a strategy for stormwater treatment across the
city centre area.
Artillery
Drive Stormwater Upgrade Project
32. This project
involves providing a large stormwater tunnel to service greenfields land in
Takanini at an estimated capital cost of approximately $22 million. The project
objective is to provide stormwater infrastructure for growth and to remove the
existing stormwater constraints (flooding).
33. This project, in
conjunction with the Takanini Conveyance Cascades project (see below) and Grove
Road Box Culvert Stormwater Upgrade, will enable development of approximately
1,500 properties in Takanini.
34. Construction of
this project is underway and it is expected to be completed by June 2017.
35. Engagement with mana whenua: A site walkover and workshop were offered to all 13 iwi with an
interest in the rohe. Representatives from Ngati Tamaoho, Te Akitai Waiohua and
Ngai Tai ki Tamaki attended.
36. Overall iwi supported the project but raised some key issues of
concerns such as the quality of
stormwater being discharged to Pahurehure Inlet and the need for iwi monitoring
of some aspects of construction.
37. Iwi also expressed interest in being involved in the design of the
outlet – by introducing design elements to the structures (e.g. railings and
decal designs on the concrete structure) to reflect local history and the
significance of Pahurehure Inlet to iwi.
38. Council has
integrated this feedback into the design of the project in various ways – for
example, iwi will monitor some aspects of construction and Māori design elements will be introduced
into the outlet.
Takanini
Conveyance Cascades
39. This project
involves the construction of a large stream to provide stormwater
infrastructure for growth in Takanini and remove existing flooding. It will
deliver flows from the 160 hectare catchment to Grove Road culvert and
ultimately the McLennan Wetland and Artillery Drive Tunnel at an estimated
capital cost of approximately $40 million.
40. This project,
in conjunction with the Artillery Road Tunnel (described above) and the Grove
Road Box Culvert will enable development of approximately 1,500 to 2,500
properties in Takanini, the majority of which are Special Housing Areas.
41. The
designation for the land required to develop the project was notified in
September 2014. The resource consent will be notified during May 2016 and a
combined designation and consent hearing is expected in July or August 2016.
42. Engagement
with mana whenua: Five iwi have indicated a desire to be engaged on the
project: Ngāti Tamaoho, Ngāti te Ata, Ngai Tai Ki Tamaki and Te
Akitai Waiohua. A hui was held last year to discuss how mana whenua values
could incorporated into the project. Ngāti Tamaoho, Ngāti te Ata and
Te Akitai Waiohua attended.
43. Iwi indicated
their general support for the project and a desire to be part of the design
team. This will be implemented through a series of design workshops during the
detailed design component of the project. The first of these will be held in
June or July this year.
44. Māori
artworks will be incorporated into the design and, where possible, training
schemes run by local mana whenua for planting of the constructed stream.
Other
major stormwater initiatives
45. In addition to
the capital works projects described above council is also working on a number
of other major projects to improve our stormwater management. These are
described below:
Collaboration with
Watercare, Auckland Transport, Panuku Development Auckland and the New Zealand
Transport Agency (NZTA)
46. Council actively
collaborates with Watercare and Auckland Transport on joint stormwater
projects. A number of opportunities for future collaboration are being
investigated and reviewed, including, but not limited to:
· Okahu Bay Separation – the design of the
works to separate wastewater and stormwater pipes is now complete. The project
will be delivered in two stages. The first stage involves works to support the
Special Housing Area at Bastion Point and tendering is expected to begin in
June 2016. The construction works for the second stage are currently being
programmed.
· Picton Street and Angelsea Street
separation, rehabilitation and flood mitigation works – the design and
geotechnical investigations are underway.
· Franklin Road upgrade and separation of
wastewater and stormwater pipes – tenders for the construction works have been
received and negotiations are underway. The tender award is expected to occur
in May or June 2016 with works scheduled to be completed by January 2018.
· Dorset Street – works to separate
wastewater and stormwater are underway.
· Van Damme Lagoon, Panmure – Auckland
Manukau Eastern Tamaki Initiative wetland upgrade project is now complete.
· Waiheke Island – council’s stormwater
team provides input into the design of Auckland Transport renewal projects.
· Three Kings separation of wastewater and
stormwater – tenders for the construction works have been received.
· St Mary’s Bay Water Quality Improvements
– an initial workshop between Watercare, Panuku Development Auckland and
council staff was held to look at water quality issues and potential options
for improvements. Further workshops are planned during May and June 2016.
· Transform Manukau - council’s stormwater
team is providing input into the redevelopment of the Manukau city centre and
crown land holdings being undertaken by Panuku with the objective of achieving
improved water quality outcomes
· East – West Connection
- council’s stormwater team is providing input into NZTA’s options analysis and
design to achieve improved water quality outcomes.
Special
Housing Areas (SHAs)
47. The stormwater
Special Housing Area team continues to support Auckland Council to deliver the
targets of the Auckland Housing Accord by supporting plan variations and
qualifying developments, engineering approvals and infrastructure funding
agreements.
48. Council’s water
sensitive design approach to new developments, aimed at protecting streams and
floodplains and providing on-site treatment for contaminants and the protection
of stream baseflow, has been well received by developers, iwi and their consultants.
49. This approach
has enabled significant new development as controlling stormwater at source
means that council is not reliant on creating large communal stormwater devices
on land under the control of third parties. This reduces the potential for significant
delays to development, which can often be caused by creating such communal
stormwater devices.
Stormwater
Network Discharge Consent
50. The stormwater department is in
the process of finalising the consent application documentation for an Auckland-wide
Stormwater Network Discharge Consent. It is intended that the consent will be
lodged with the regulatory arm of Auckland Council in June 2016. The consent is
required under the Resource Management Act to give council authority to divert
and discharge stormwater from the public urban network.
51. The aim of the consent is to set
forward a framework for how Auckland Council, as stormwater infrastructure
providers, will manage and reduce the community, environmental and cultural
effects from stormwater assets under its control. These include effects from
poor performing assets, growth, flooding, stream, coastal and groundwater
health, as well as effects on the operation of the wastewater network
52. Consultation with all 21 local
boards on the Network Discharge Consent is complete.
53. Engagement with mana whenua:
All 19 iwi were asked to give input into the Auckland-wide Network Discharge
Consent. This consultation focused on the proposed framework of the consent and
what that will mean for the management of stormwater in their rohe.
54. Feedback to date on the consent includes:
· Maori have kaitiakitanga responsibilities
to ensure the mauri of water is preserved. Water in all its forms is a
fundamental resource and a taonga to the Māori people. Stormwater management across all receiving environments
is a high priority for iwi and mātauranga Māori should be incorporated into stormwater management practices.
· Priority should be given to reducing
contaminant loads and holistic contaminant management is very important.
Wastewater contaminating waterways is a significant concern to iwi.
· Council should be proactively promoting
best practice stormwater management and should lead by example, such as through
greater use of systems and technologies such as rain gardens or other
innovative ways of treatment.
· A big concern is the piping of streams
and allowance of on-line ponds (ponds within a stream). Streams should at least
be maintained, but should be enhanced if possible.
· There was general concern expressed about council’s regulation of
development. Iwi would like to have a greater level of input in the concept
design for all new developments.
55. Feedback received has been incorporated and
reflected into the consent conditions, which are currently in the process of
being drafted. Ongoing consultation with iwi on the consent is programmed for
June 2016.
One Plus – A
consolidated asset management system for stormwater
56. Council has developed a
stormwater management asset system known as One Plus. The aim of this project
was to improve asset management practices, processes and tools, to ensure the
stormwater asset system and services are being effectively managed.
57. By
establishing a single asset management system for council’s stormwater assets
council has replaced seven geographic information systems and four asset
management systems created by legacy councils. This completed project is
generating a number of benefits including:
· savings on license fees for
software
· improved ability to
efficiently capture, manage and share asset based information
· enhanced decision making in relation to
asset management.
58. One Plus became operational in
December 2015. Work is underway to identify additional system improvements and
efficiencies.
Engaging
with mana whenua
59. Stormwater has streamlined its
process for engaging with mana whenua on stormwater projects. All mana whenua
are now receiving a monthly update on stormwater projects across the region.
Closed landfill and contaminated land response projects are also being included
in the list. This approach allows mana whenua to prioritise the projects that
are of most importance to them for further engagement.
60. Through this process iwi are
giving feedback on a wide range of stormwater projects, including through site
visits, kaitiaki reports or Cultural Impact Assessment (CIA)s. Table One below
provides a summary on the level of consultation during the update period:

61. Council’s
stormwater team is also carrying out ongoing work to ensure that mana whenua
engagement on major stormwater projects starts early in the design process and
leads to meaningful outcomes.
Consideration
Local
Board views and implications
62. Information
about major capital stormwater projects is provided to local boards through
regular quarterly performance update reports. Council officers also work
closely with local boards on regional stormwater issues and projects within
their local board areas.
63. A number of
engagement activities with local boards on specific stormwater projects have
been carried out during the update period, including:
· the environmental portfolio holder for
the Puketāpapa Local Board
was involved in the steering group for the Te Auaunga Awa stormwater project.
· a workshop was held with the Ōrākei Local Board on the Portland Road stormwater issue and regular
updates provided on the Madills Farm stormwater project.
· regular updates provided to Manurewa
Local Board on the Wattles Down project.
· update to the Albert-Eden Local Board on
the Daventry Road Waterview separation and stormwater upgrade project.
Māori
impact statement
64. Stormwater and environmental
management have integral links with the mauri of the environment and concepts
of kaitiakitanga.
65. As described above in the body of
the report, council recognises the significance of stormwater management to
mana whenua and is undertaking in-depth engagement on a number of major
stormwater projects.
