Comments
5. Delivery of
council’s stormwater capital works programme is slightly ahead of schedule for
the 2014/15 financial year with an actual spend of $61.94 million against a
budget of $60.09 million up to 31 May 2015. The full year forecast remains
within the approved budget of $65 million and is on track for delivery.
6. 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.
Major stormwater capital works projects
Te Auaunga Awa – Walmsley and Underwood Reserves
Rehabilitation Project
7. The primary
objective of this project is to undertake flood alleviation works to reduce
flooding and to provide for growth in the Oakley stormwater catchment at an
estimated capital cost of $20 to $22 million.
8. The preliminary
design of this project is progressing well and the detailed design is on track
to begin in the middle of this year.
9. The project
will be a fully notified consent and the application will be lodged at the end
of June 2015. To enable this the project team are working closely with the
three affected Local Boards (Whau, Albert-Eden and Puketāpapa) to gain landowner approval.
10. The project is
being delivered through a collaborative approach to ensure strong community
engagement and ownership.
11. Reflecting the
collaborative nature of this project, iwi representatives have been appointed
to the steering group and the project working group. Iwi representatives have
been working closely with the design team to incorporate matauranga Māori where possible.
12. On 14 March 2015
a community project open day was held which approximately 200 people from the
local community attended. This event included a survey of the local community
to understand how they currently use their reserves and what they would like to
see in the reserves in the future.
13. A number of
local schools have been approached and indicated a willingness to engage with
the project including Owairaka Primary, Wesley Intermediate and Wesley Primary.
The project team has also held workshops with the kids from Owairaka Primary
School asking them how they currently use the reserves and what they would like
to potentially see in their new reserve. This information has been
incorporated in the preliminary design.
14. Below are some
of the pictures that the children painted of how they would like to see their
stream. These drawings have been adopted as the project logo, as shown in
Figure One.
Figure One:
Project logo for Te Auaunga Awa
15. Council is also
investigating the possibility of addressing youth employment in the
construction phase of the project. The local community has high youth
unemployment so the project team is working with potential contractors to find
ways to address this issue within the physical works contract.
Artillery Drive Stormwater Upgrade
Project
16. This project
involves providing a large stormwater tunnel to service recently released
greenfield 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). This
project, in conjunction with the Takanini Conveyance Cascades project (see
below), will enable development of approximately 1,500 properties in Takanini.
17. Detailed design
of the project is complete. Tender documents and specifications are currently
being reviewed. An application for resource consent was lodged through the
Housing Project Office on 9 March 2015 and it is anticipated it will be
finalised within the next month.
18. Expressions of
interest have been received and evaluated for the construction phase of the
project. Subject to acceptable consent conditions being granted, a request for
tenders will be sent out to the successful contractors identified through the
expression of interest process.
Takanini Conveyance Cascades
19. This project
involves providing a large stormwater channel in the proposed Artillery Drive
Tunnel that will service recently released greenfield land in Takanini at an
estimated capital cost of approximately $20.5 million. The project objective is
to provide stormwater infrastructure for growth and remove the existing
stormwater constraints (flooding). This project, in conjunction with the
Artillery Road Stormwater Upgrade Project described above, will enable
development of approximately 1,500 properties in Takanini.
20. The project is
in the preliminary design phase. The designation for the land required to
develop the project was publicly notified in September 2014. A hearing on the
designation and related earth works consent is expected to be held during
September 2015.
Wynyard Quarter Stormwater Upgrades
21. 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.
22. The design and
construction flood alleviation works are programmed to be split into three
discreet work packages to coincide with the proposed road upgrades and development
requirements of Auckland Transport and Waterfront Auckland respectively.
23. A Memorandum of
Understanding with Auckland Transport has been signed and agreement on the
scope of the first package of works will be finalised once more information on
investment through a tendering process is complete.
24. Council is also
working with Waterfront Auckland to finalise a proposed Memorandum of
Understanding with them for their construction works. This project has also
been tendered to confirm prices and the scope of works.
Ports of Auckland Stormwater Upgrade Project
25. The objective of
this project is to rehabilitate or replace the Stanley Street outfall pipeline
which is in need of renewal. This will resolve extensive flooding in the area.
26. The scope of the
project includes construction of a substantial culvert (likely width around 3.3 metres) from the rail corridor, across Quay
Street and through Ports of Auckland land to the sea. The project will
supplement or replace the existing stormwater pipeline and will address
flooding in the lower catchment and Britomart entrance.
27. The Early
Contractor Involvement contract to develop the concept design and undertake
further investigation was awarded to McConnell Dowell. Initial consultation
with stakeholders including Ports of Auckland, Auckland Transport, KiwiRail and
iwi has been undertaken.
28. Preliminary work
to identify practicable options considering cost, risk and hydraulic
performance has been undertaken and preferred alignment corridors for the project
have been identified for further investigation.
Other major stormwater initiatives
29. 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 and
Auckland Transport
30. 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 – detailed design underway – phase 1 construction programmed for
2015/2016
· Picton
Street and Angelsea Street separation, rehabilitation and flood mitigation
works – design underway
· Franklin
Road upgrade and separation – business case approved for implementation.
Initial design and implementation meetings held with Auckland Transport and
Watercare.
· Castle
Street to Fife Street stormwater extension – design and construction to be
included in Stanmore and Fife stormwater project.
· Dorset Street – design underway
· Van Damme
Lagoon, Panmure – Auckland Manukau Eastern Tamaki Initiative wetland upgrade
project.
Special Housing Areas (SHAs)
31. The Stormwater
Special Housing Area team continues to support The Housing Project Office (HPO)
to deliver the targets of the Auckland Housing Accord.
32. The Stormwater
Management Plans (SMPs) for key SHAs such as Crows Road, Scott Point, Belmont,
Hingaia Karla, Huapai Triangle, Oruarangi Road, Wesley and Hingaia Karaka Lakes
South are all substantially complete and are in the final stages of review.
33. Stormwater
approaches are being developed and agreed for Whenuapai 2, Flat Bush, Oraha
Road (Huapai), Hingaia Summerset, and Redhills. The stormwater management
planshave required substantial collaborative effort between council staff,
Auckland Transport, private developers and their consultants. The Whenuapai
Plan change hearing was held in December 2014, the Wesley hearing was held in
May 2015 and Scott Point is scheduled for June 2016.
34. Development of
the stormwater infrastructure in partnership with the developer of the SHA at
Weymouth is progressing well and completion is expected in June 2015.
35. Detailed
negotiations are underway to agree on interim arrangements for stormwater
solutions, allowing developers to proceed, prior to final infrastructure being
completed in Hingaia, Huapai, Takanini and Tamaki. Council is also continuing
to progress the design of stormwater solutions in other SHAs in New Lynn,
Tamaki North, Takanini and Okahu Bay.
36. As part of the
collaborative approach undertaken by the SHA office, council is working closely
with mana whenua on the development of stormwater management designs for SHAs,
the most recent examples being the Hingaia Peninsula, Takinini Cascades and
Belmont SHAs.
37. Council’s water
sensitive approach to these developments, aimed at protecting streams and
floodplains and providing on-site treatment for contaminants and the protection
of stream baseflow, is strongly supported by iwi. As a result, iwi and the
council have been working together with developers on designing water sensitive
stormwater solutions for SHAs.
Stormwater Bylaw
38. A stormwater
bylaw is being developed to provide a consistent regulatory approach for
stormwater management across Auckland.
39. The
deliberations meeting of the Stormwater Bylaw Hearings Panel was held on 28 May
2015. The Stormwater Bylaw was approved by the Hearing Panel to be referred to
the Governing Body for approval, subject to a few minor edits. The Stormwater
Bylaw is expected to come into force on 1 November 2015.
40. Adoption of this bylaw will enable council to ensure:
· that the
public stormwater network and private stormwater systems are of a consistently
high standard throughout Auckland
· require
on-site stormwater devices on private land to be well maintained
· manage activities on private property
that have adverse impacts on the public stormwater network.
Stormwater Network Discharge Consent
41. Council is working with Auckland
Transport to finalise an application for an Auckland-wide Stormwater Network
Discharge Consent. This is required under the Resource Management Act to give
council authority to divert and discharge stormwater from the public urban
network.
42. The aim of the consent is to set
forward a framework for how Auckland Council and Auckland Transport, as
stormwater infrastructure providers, will manage and reduce the community,
environmental and cultural effects from stormwater assets. 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.
43. Council is currently undertaking
consultation with all 21 Local Boards on the Network Discharge Consent as well
as with mana whenua who have indicated interest in this application. This
consultation focuses on the proposed framework of the consent and what that
will mean for the management of stormwater in their areas of interest.
44. Additional consultation is also
being undertaken with key stakeholders, including community, business and
recreational groups, in the Hibiscus Coast and Eastern Bay areas, to identify
their priorities for the management of stormwater infrastructure.
45. The current timeframe for
officially lodging the consent with council’s regulatory department is late
2015.
One Plus
– A consolidated asset management system for stormwater
46. Council is developing a
stormwater management asset system known as One Plus. The aim of this project
is to improve asset management practices, processes and tools, to ensure the
stormwater asset system and services are being effectively managed.
47. The
objective of the project is to establish a single asset management system for
council’s stormwater assets, thereby replacing seven Geographic Information
Systems and four asset management systems created by legacy councils. This will
have 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.
48. As at
June 2015 the overall design phase of One Plus is 95 per cent complete and the
build phase is progressing well. The project is on track for delivery with the
following milestones:
· One Plus Solution Build
complete – July 2015
· Systems Integration Testing
– August 2015
· User Acceptance Testing –
October 2015
· Training for users –
October 2015
· Go live – 30 November 2015
· Decommission legacy systems – February
2016.
Engaging with mana
whenua
49. Council routinely engages with iwi on stormwater
issues. Table One below provides a summary of the level of consultation
undertaken on stormwater projects between February 2015 and May 2015.

50. In
addition to project specific engagement, ongoing one-to-one meetings are
continuing with mana whenua who wish to engage at this level.
51. As a result of
feedback from these meetings, staff are trialing a revised consultation process
on stormwater projects for mana whenua as a means of streamlining engagement.
52. A number of
issues have also been raised by mana whenua relating to specific stormwater
projects in their area or concerns relating to their rohe. Some general themes
that have been consistently raised include the need for council to prioritise
improving water quality, protect cultural heritage and manage the stormwater
impacts of growth and development.
53. Work to address
this feedback through council’s management and development of stormwater
infrastructure is ongoing.
Consideration
Local
Board views and implications
54. 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.
55. A number of
engagement activities with local boards on specific stormwater policies and
projects have been carried out during the update period, including.
· Consultation with all 21 local boards on
the stormwater network discharge consent.
· Workshops in April 2015 with Albert-Eden,
Puketāpapa and Whau Local
Boards in relation to the Te Auaunga Awa project. Reports seeking formal
land-owner approval for project works were put to each board in May and June
2015.
· Approval in principle was given from the
Maungakiekie-Tāmaki Local
Board in May 2015 for the construction of a wetland in the Elstree Reserve and
part of the Tamaki College grounds to accommodate and manage the stormwater
from the development of the Tamaki Transformation Project. The local board
remains involved in the detailed design process for the project.
· Engagement with the Orākei Local Board portfolio holder to
discuss the Madills Farm stormwater project, and to request landowner consent
for construction equipment on site.
· Engagement with the Papakura Local Board
portfolio holder in June 2015 to update them on progress on the Elliot Street
stormwater project.
· A workshop will be held in July 2015 with
the Māngere-Ōtāhuhu Local Board to discuss the remediation plan for the Oruarangi
Awa post the dye spill two years ago.
· An agenda item was considered by the
Devonport-Takapuna Local Board in May 2015 to identify solutions to issues
relating to stormwater outfalls on Takapuna Beach. A cross-council group is
looking into further options and some alternative solutions will soon be
presented to the board for their consideration.
