Updated procurement plan for Corban Reserve stormwater upgrade – stage one

File No.: CP2021/02610

Te take mō te pūrongo

Purpose of the report

1. To note an update on the procurement plan for stage one physical works for the Corban Reserve stormwater upgrade project.

Whakarāpopototanga matua

Executive summary

2. The Corban Reserve stormwater upgrade project is required to eliminate a known health and safety risk.

3. The project has been commissioned and designed to safeguard public health and safety through elimination of methane and leachate infiltration from the closed landfill into the existing public stormwater network.

4. The project will also alleviate flooding risk and provide for the future growth of the upstream catchment. Water quality of the Opanuku Stream is also anticipated to improve following the elimination of leachate discharge through the stormwater network.

5. The project is structured into three stages. Stage one consists of the construction of a stormwater pipe from 18 Imperial Place in Henderson to the Opanuku Stream to divert the stormwater network away from the Corban Reserve closed landfill. Stage two will decommission the existing stormwater pipe underneath Corban Reserve. Stage three will upgrade the undersized local stormwater network between 165 and 139 Henderson Valley Road, Henderson.

6. The procurement plan for the project was originally approved by the Strategic Procurement Committee in August 2019 (STR/2019/59). Due to the significant financial impacts of COVID-19, construction of the project was then deferred for 12 months through the Emergency Budget.

7. During this time the council has actively monitored and managed risks at the site.

8. More details on the procurement plan for stage one of the Corban Reserve stormwater upgrade will be provided in the confidential section of the 13 April 2021 Strategic Procurement Committee meeting.

Ngā tūtohunga

Recommendations

That the Strategic Procurement Committee:

a) note the information contained in this report on the procurement plan for stage one of the Corban Reserve stormwater upgrade project, enables transparency on the topic due for discussion in the public excluded part of the meeting

b) note that the confidential report contains commercially sensitive information relating to the procurement of the proposed works for the stormwater upgrade which could prejudice council's position in negotiations with suppliers.

Horopaki

Context

9. A stormwater pipe that runs through a closed landfill in Corban Reserve has been identified as posing an on-going health and safety risk to the public and council staff, due to the presence of landfill gases.

10. Monitoring shows that the pipe is collecting methane gas from the closed landfill at levels which are potentially explosive if ignited. A methane explosion during stormwater upgrade works at the site in 1996 resulted in a fatality.

11. Leachate from the closed landfill is also infiltrating into the stormwater pipe, resulting in elevated heavy metals and levels of ammoniacal nitrate being discharged to the Opanuku Stream.

12. In addition, flooding of residential properties upstream of the pipe is frequent due to existing downstream capacity constraints and debris blocking the inlet to the stormwater pipe. The creation of the landfill has also resulted in an embankment, blocking the natural overland flow path and flooding properties. Flooding of upstream residential properties is currently reported up to five times per year and 21 properties are at risk of flooding in a one per cent annual exceedance probability storm event.

13. Council is managing these risks in the short-term through various measures, such as close monitoring of the landfill site and the use of a ventilation system in Corban Reserve to safely disperse gases over reserve land. However, a more permanent solution is needed.

14. Analysis conducted by council staff indicates that construction of a new stormwater pipeline and decommissioning the piped section through the closed landfill is the only way to effectively eliminate these risks.

Works will be delivered in three stages

15. Auckland Council is progressing the delivery of this stormwater upgrade project in three stages. Stage one of the Corban Reserve stormwater upgrade project is to divert stormwater flows from the 78-hectare Waitaro Stream catchment away from the existing pipe under the closed landfill site at Corban Reserve. To achieve this, a new pipeline will be tunnelled along Border Road to the Opanuku Stream.

16. Stage one of the project also includes the enhancement of nearby Murillo Reserve by removing a section of pipe through the reserve; installing a low flow pipe between the main pipeline and daylighted section within Murillo Reserve; stream naturalisation upstream of Corban Reserve; and minor upgrades to Border Road Esplanade including new shared path, boardwalk and planting. A new inlet and work on the open channel upstream to reduce the likelihood of inlet blockage will be included.

17. Stage two of the works is to decommission the existing stormwater pipe underneath Corban Reserve. The reserve will then be upgraded with new signage and footpaths, recontouring to improve drainage, and planting.

18. Stage three of the works is to upgrade part of the local stormwater network between 165 and 139 Henderson Valley Road, Henderson. This will include installing a new larger pipe within the road berm and replacing the pipe across Henderson Valley Road.

Deferral of works due to financial impacts of COVID-19

19. Prior approval for stage one of the project was granted by the Strategic Procurement Committee in August 2019. The project was then deferred for 12 months due to the Emergency Budget.

20. During this time period the council has continued to monitor the site. Unmanned entry surveillance has been adopted during this time to ensure safety of operations staff.

21. Further context will be presented in the confidential section of the 13 April 2021 Strategic Procurement Committee meeting.

Tauākī whakaaweawe āhuarangi

Climate impact statement

23. The proposed project will not have a significant impact in terms of climate mitigation (reducing emissions). It will contribute to adaptation by increasing Auckland’s resilience to climate impacts. Preparing Auckland for the impacts of climate change is a key goal of Te Tāruke-ā-Tāwhiri: Auckland's Climate Plan.

24. The upgrades to the stormwater network at Corban Reserve are based on modelling of climate change impacts, including more extreme weather events. They will provide increased capacity in the stormwater network to manage these climate impacts.

25. Additional impacts arising from the procurement plan for stage one of the Corban Reserve stormwater upgrade project will be provided in the confidential section of the 13 April 2021 Strategic Procurement Committee meeting.

Ngā whakaaweawe ā-rohe me ngā tirohanga a te poari ā-rohe

Local impacts and local board views

Local impacts

26. This project will significantly reduce health and safety risks to Council and its employees by removing landfill gas from the stormwater network. It will also improve ecological values by preventing leachate entering the Lower Waitaro and Opanuku Streams. Additional ecological habitat will also be provided through daylighting the current piped network at Murillo Reserve and restoration of the Upper Waitaro Stream above the proposed pipe network.

27. The new pipeline will also help to increase the capacity of the local stormwater network and reduce flooding of residential properties upstream of the pipe under Corban Reserve.

28. The project will also have significant positive benefits for people living in the surrounding area through increased amenity at Murillo Reserve, Border Road Esplanade and Corban Reserve. The daylighting at Murillo Reserve will include a new pedestrian bridge, seating and planting. A new boardwalk and path from Taranui Place to the Border Road Esplanade will provide additional connectivity with the Twin Stream Cycleway, along with improved planting by the Border Road entrance. Corban Reserve will be upgraded as part of stage two of the Corban Reserve stormwater upgrade project incorporating new footpaths, planting and signage.

Local board views

Māori impact statement

30. A project brief was provided to mana whenua in October 2016 with an updated version presented in January 2018. Both Te Rūnanga o Ngāti Whātua and Te Kawerau ā Maki expressed an interest in the project.

31. A site visit with both iwi was hosted by Healthy Waters. The current discharge of leachate was considered by mana whenua to be severely detrimental to the mauri of both the Waitaro Stream and Opanuku Stream and the removal of leachate therefore essential. Both iwi requested that erosion of Opanuku Stream also be considered as part of project design. The potential erosion impact on Opanuku Stream has been carefully mitigated in the design of the outfall and the mauri of the Waitaro Stream will be improved by the removal of leachate.

32. The mauri of two other sections of the Waitaro Stream will also be significantly improved through the removal of the concrete lined channel, regrading, naturalisation and planting of the stream above Corban Reserve and daylighting and restoration of Waitaro Reserve at Murillo Reserve.

33. Te Rūnanga o Ngāti Whātua and Te Kawerau ā Maki confirmed their support for the project and a Cultural Impact Assessment from Te Kawerau ā Maki was received in October 2018 confirming this also.

34. The project team has continued to work in partnership with iwi on the design of the project. Specific design elements have been incorporated into the upgrade to Murillo Reserve to reflect the aspirations of iwi and their cultural history.

35. Further information will be presented in the confidential section of the 13 April 2021 Strategic Procurement Committee meeting.
