7.   Banks Peninsula Zone - Monitoring Results 2017-2018

 

Committee Comment

Dr Tina Bayer, Surface Water Scientist, in addition to her written report, provided an illustrated update on Banks Peninsula’s Water Quality and Ecosystem health.

 

There was discussion following the presentation and key points included::

·        Concern about why stream sites with poor results were getting worse

·        The importance of using mahinga kai as an indicator for monitoring the health of Banks Peninsula streams.

·        Question regarding the potential source of nitrogen, given that farming stock rates have not increased in the last 10 years.

·        The need for further information about ‘tunnel gully’ erosion.

Dr Tim Davie, Chief Scientist, advised that there are four key drivers of poor ecosystem health and these all relate to habitat:

·        Sediment

·        Temperature

·        Shading

·        Water Quantity

It was noted that in Te Roto o Wairewa Lake Forsyth there is a significant declining trend in Total Phosphorous (TP) and Total Nitrogen (TN).  However trends in chlorophyll a and turbidity were not significant. 

 

Committee Decisions under Delegation

That the Banks Peninsula Water Management Zone Joint Committee:

1.         Receive the summary of monitoring information.

2.         Recommend these monitoring results be part of the knowledge base that informs decisions on any intervention projects to improve water quality and/or ecosystem health.

3.         Have an item on next month’s agenda – “How do we assess mahinga kai as part of our State of the Takiwa monitoring?”

4.         Receive more information about the investigation into the effects of stream water quality on beach swimming water quality.

 

 

8.   Okains Bay Water Supply

Banks Peninsula Water Management Zone Joint Committee

16 October 2018

 

 

 

 

7.        Matters Relating to the Zone Committee Process

Reference:

18/1056982

Presenter(s):

Olivia Smith, Zone Facilitator

 

 

1.   Purpose of Report

1.1       The purpose of this report is for the Banks Peninsula Water Management Zone Joint Committee to be updated on some matters relating to the Zone Committee process.

2.   Staff Recommendations

That the Banks Peninsula Water Management Zone Joint Committee:

1.         Receive the information in the report on matters relating to the Zone Committee process.

3.   Report

3.1       Zone Committee Recommendations to Councils

In September, the Zone Committee raised concerns about how committee recommendations are considered by Councils.  Members questioned why Zone Committee recommendations are not considered by Christchurch City Council (CCC) governance given the Zone Committee is a governance group established by CCC and Environment Canterbury.  Members also questioned how zone committees could have more effective input into Long Term Plans and Annual Plans.  These matters were raised by the Zone Committee Chair at the Christchurch City Council meeting on 6 September and the resolution below was passed.  Both Councils will report back to the Zone Committee on this matter in November 2018.

 

Council Resolved CNCL/2018/00183

That the Council:

 

1.      Receive the information in the Zone Committees’ report.

2.      Notes the request from the Banks Peninsula Water Management Zone Committee requesting Christchurch City Council consider providing Sam Hampton with an opportunity to evaluate the results of the deep bore injection trials for the Akaroa Wastewater disposal and refer the matter to staff to follow up.

3.      Request staff to meet with the Zone Committee representatives to develop a mechanism for ensuring appropriate input into relevant Council decision making processes, and report back by the end of November 2018.

Deputy Mayor/Councillor Clearwater Carried

 

Committee members also raised questions about progress with actioning recommendations. Each month, a table will be included in the Facilitators Update which outlines Zone Committee recommendations and the progress status of each.

 


 

 

3.2       Zone Committee 3 Year Action Plan

The final version of the Zone Committee 3-year Action Plan is attached to the Facilitators Update. The Action Plan will be used to inform agenda items at future meetings and at each meeting it will be made explicit what actions from the plan are being progressed.  Each quarter the Zone Committee will receive a report which details progress with implementing the plan.

 

3.3       Register of Interests

In June Zone Committee members suggested that it would be beneficial to have a register of Zone Committee member interests, like some other zone committees in Canterbury. From November there will be a standing item at the start of the agenda that includes a table listing the relevant interests of each Zone Committee member. At each Zone Committee meeting, committee members will be asked if there are any changes to the register of interests. 

 

3.4       Zone Committee Venues

The November Zone Committee meeting will be held in Wainui and will include a field trip. At the November meeting, the list of venues for the first six months of 2019 will be agreed. This will enable bookings to be made well ahead of time.

9.        Environment Canterbury Zone Team Update

Reference:

18/1057172

Presenter(s):

Gillian Jenkins, Zone Lead

 

 

1.   Purpose of Report

1.1       The purpose of this report is for the Banks Peninsula Water Management Zone Joint Committee to be briefed on the work of the Environment Canterbury Zone Team to help deliver the Zone Committee 3-Year Action Plan.

2.   Staff Recommendations

That the Banks Peninsula Water Management Zone Joint Committee:

1.         Receive the update and note that the proposed Farm Environment Plan workshop in Okains Bay will be delayed till 2019.

2.         Confirm that Committee support further work to understand and provide advice on drainage issues in Okains Bay.

3.   Report

3.1          FEP Workshops (relates to Action 8)

We have been in touch with Beef and Lamb to discuss organising the next Farm Environment Plan (FEP) workshop for Okains Bay. They are unavailable in November due to another workshop, so we will look to hold this in the New Year.  Our new Land Management Advisor will be inducted by then so will be able to take on more of a role here.

3.2          Okains Bay Drainage Issues (relates to Action 24)

The Zone Committee have previously enquired about what support the Environment Canterbury engineering team could provide to areas on Banks Peninsula that are outside the Wairewa rating district. The engineering team have advised that they have some capacity to provide advice on drainage issues including the nature of the issues, consenting requirements and a brief plan of works that would need to be undertaken. The team can also provide support with establishing a rating district if appropriate. It should be noted that rating districts are only suitable in some circumstances where ongoing, co‑ordinated maintenance is required and where there is community support.  Two members of the engineering team have offered to visit Okains Bay to provide advice on some of the issues that have previously been raised by the Zone Committee. They will do so with the Committee’s support.

3.3          Hui at Wairewa (relates to Action 16)

Environment Canterbury councillors and staff were invited to attend a hui at Wairewa Marae earlier this month with Onuku and Taumutu runangas. We continue to keep the Wairewa Bank Stabilisation Project in the forefront of minds and this was mentioned at the hui. It was a great chance to hear each Rūnanga and their concerns.


 

3.4          Port Hills Biodiversity Hub (relates to Action 26)

ECan staff and councillors attended a meeting at Living Springs on 4 October regarding a proposal to set up a biodiversity hub on the Port Hills (encompassing parts of both sides of the hills). The meeting was to gauge community interest and support for the idea. Many relevant groups were present and interested so the idea may progress further. The BPCT facilitated the meeting and was particularly interested in getting feedback on the topic and knowing which landowners should or would like to be included in discussions.

3.5          Whakaraupo/Lyttelton Harbour Catchment Management Plan (relates to Action 1)

A Programme Manager is due to be appointed soon. Their role will be to develop and implement the work programme for the plan. A fair part of this will be to engage with the community. A group will be set up and this group will be a good opportunity for the Zone Committee to tie into the plan so that activities can be co-ordinated well.

 

A more comprehensive update on the implementation of the Zone Committee 3-year Action Plan will be provided to the Zone Committee on a quarterly basis.

10.    Update on the Significant Ecological Sites Programme and Christchurch City Council Biodiversity Fund

Reference:

18/1058860

Presenter(s):

Laura Molles, Advisor Natural Environment, CCC

 

 

1.   Purpose of Report

1.1       The purpose of this report is for the Banks Peninsula Water Management Zone Joint Committee to be updated on the Significant Ecological Sites (SES) programme and the Christchurch City Council Biodiversity Fund.

2.   Staff Recommendations

That the Banks Peninsula Water Management Zone Joint Committee:

1.         Receive the Update on the Significant Ecological Sites Programme and Christchurch City Council Biodiversity Fund report.

2.         Provide advice on how to increase awareness among Banks Peninsula landowners about the SES programme and the availability of the Biodiversity Fund.

3.   Background

The Canterbury Regional Policy Statement 2013 (prepared by the Regional Council) requires the Christchurch City Council to identify areas of significant indigenous vegetation and significant habitat of indigenous fauna. These areas are called Sites of Ecological Significance, or SESs.

 

The current District Plan, like previous Christchurch City and Banks Peninsula District plans, includes policies and rules which aim to protect indigenous vegetation and habitats of indigenous fauna. This includes rules for activities such as vegetation clearance, earthworks and waterway setbacks. With several important exceptions, clearance of indigenous vegetation of types listed in the District Plan Appendix 9.1.6.6 (but not currently identified as being within an SES) and vegetation clearance within an identified SES are both activities that require resource consent. Exceptions include maintenance of fences, farm tracks, and improved pasture. The exceptions also apply regardless of whether the vegetation has been identified as an SES or is of one of the vegetation types listed in the District Plan.

 

A key benefit of the SES programme is that it provides a clearer understanding to both landowners and the Council regarding where the clearance rules apply. This is important because while some vegetation types – like mature indigenous forest – are very easy to recognise, other ecologically important habitats and species are less familiar or harder to identify.

 

To identify these sites, a Council ecologist undertakes a site assessment using a set of criteria which help to determine significance including: representativeness, rarity or distinctive features, diversity and pattern, and ecological context.

 

Many SESs have been included in schedules in the District Plan - Schedule A and Schedule B. Schedule A includes sites identified on public land and, following collaboration, where private landowners have agreed to the inclusion of the site on the schedule. Schedule B includes ecological sites on private land that require further collaboration with landowners. It is intended that as this collaborative process is completed sites will be added to Schedule A by way of plan change.

 

There is a large number of sites on Banks Peninsula that fall under the vegetation and habitat types listed in the District Plan Appendix 9.1.6.6, but which have not had an on-the-ground assessment. There are also many landowners for sites currently listed in Schedule B who have not yet had follow-up visits to discuss the site significance statements, proposed site boundaries, questions and concerns. Improving communication with these landowners is an important first step in re-starting the landowner discussion and site assessment process. A Draft question-and-answer document is being provided to the Committee for feedback; the Council would like to identify the key issues landowners would like addressed, and how to best communicate this information.

 

When a site is identified as an SES, landowners are not required to take active protection measures like fencing or removing stock. However, some landowners may be interested in taking active measures for part or all of an SES, or are already doing so, and would like assistance. To assist these landowners, the Council have established a contestable biodiversity fund of $200,000 per year. To be awarded funding a project must meet all of the following criteria:

 

·      achieve positive biodiversity outcomes; and

·      be on private land, or on land which is defined under the Te Ture Whenua Māori Act 1993 as customary land; and

·      be identified as a Site of Ecological Significance (SES) on Schedule A or B of the Christchurch City District Plan, or meet the criteria for an SES within the Christchurch City District Plan and have an agreed site of ecological significance statement; and

·      have a management plan.

 

The fund is contestable, and applications are prioritised by the following criteria: 

 

·      protection of threatened and locally rare ecosystems e.g. wetlands, dunes, cliffs, old growth forest

·      protection of threatened or locally rare species

·      have a covenant registered on the title of the land (or be entered into as part of the funding application)

·      catchment scale to ensure connectivity between land, freshwater and the coast

·      ability to provide other benefits e.g. school and community engagement, public accessibility.  

4.   Report

 

In 2018/2018 financial year, eight projects on Banks Peninsula were awarded funding through the CCC Biodiversity Fund. These projects include Okuti River, Wainui Stream, Armstrong Stream/Mabel Hope Reserve, French Peak, Duvauchelle Peak and Paua Bay, Living Springs and Orton Bradley Park. Several of these projects are stream based and have also received funding from the Immediate Steps Biodiversity Fund.

 

Laura Molles (CCC Ecologist) will attend the Zone Committee meeting and provide an update the proposed SES’s work programme for the upcoming year. This is an opportunity to discuss how the Zone Committee and CCC can work together to ensure the FEP programme, SES programme and Biodiversity Funds are co-ordinated and complement each other.

11.    Banks Peninsula Stream Labelling Project

Reference:

18/1061529

Presenter(s):

Paula Smith, Chairperson

 

 

1.   Purpose of Report

1.1       The purpose of this report is to provide the Banks Peninsula Water Management Zone Joint Committee with an update on the Stream Labelling Project and to seek feedback from the Zone Committee on how to progress this project with the Christchurch City Council.

2.   Staff Recommendations

That the Banks Peninsula Water Management Zone Joint Committee:

1.         Discuss and agree on how to progress the Stream Labelling Project with Christchurch City Council.

3.   Report

At the Banks Peninsula Water Management Zone Committee meeting on 21 August 2018 at Te Whare Tapere o Te Mata Hapuku, Birdlings Flat, it was agreed:

 

That the Banks Peninsula Water Management Zone Joint Committee:

·   recommend to NZTA that they label three streams on State Highway 75,

·   recommend that Christchurch City Council label 15 Banks Peninsula streams.

This recommendation was agreed to help progress Action 28 in the Zone Committee 3-year Action Plan.

 

I drafted a letter to the New Zealand Transport Authority but thought I had better ground truth the situation before sending it off, which I did on the way to our September meeting at the Akaroa Recreation Centre.

 

It turns out seven streams within our zone are already labelled as they pass under State Highway 75 (refer to attachment 1). The labels are:

1.    Police Culvert

2.    Okana River

3.    Barrys Bay Creek Bridge

4.    Pawsons Stream

5.    Piper Creek Culvert

6.    Robinsons Bay Culvert

7.    Takamatua Creek

State Highway 75 ends as the road enters Akaroa township. One of the series of streams within Akaroa township, Aylmers Stream, is also labelled with the standard yellow signs. Therefore, I suggest we need do nothing more about State Highway 75 streams.

 


 

The fifteen streams on local roads which we seek labels for are:

1.      Te Wharau Stream

2.      Waiake Stream

3.      Purau Stream (may also be known as Waituturi?)

4.      Te Kawa Stream

5.      Owhetoro Stream

6.      Koukourarata Stream

7.      Holmes Stream

8.      Pigeon Bay Stream (x2)

9.      Opara Stream

10.   Le Bons Stream (x3)

11.   Okuti River

12.   Opuahou Stream

13.   Hikuika Stream

14.   Hukahuka Turoa Stream, and

15.   Te Rapu Stream (which is the only one not identified on the NZMS 1:50,000 maps)

 

Peter Kingsbury enquired on our behalf about this and was advised by Christchurch City Council roading staff that as there is no budget for this project nothing could be done.

 

At our quarterly report to the full Christchurch City Council meeting on 6 September 2018 there was some discussion with the Mayor and Councillors about how Zone Committee recommendations to the Christchurch City Council get actioned. The following resolution was passed:

 

Council Resolved CNCL/2018/00183

That the Council:

 

1.    Receive the information in the Zone Committees’ report.

 

2.    Notes the request from the Banks Peninsula Water Management Zone Committee requesting Christchurch City Council consider providing Sam Hampton with an opportunity to evaluate the results of the deep bore injection trials for the Akaroa Wastewater disposal and refer the matter to staff to follow up.

 

3.    Request staff to meet with the Zone Committee representatives to develop a mechanism for ensuring appropriate input into relevant Council decision making processes, and report back by the end of November 2018.

 

Deputy Mayor/Councillor Clearwater Carried

 

The Zone Committee could raise the matter of stream labels, as part of the discussions referred to under 3, as a case study, and see if we can get some action, if not this financial year, then possibly next.  In the meantime, another possible next step would be to write directly to Christchurch City Council's CEO.

12.    Fish Passage in Stormwater Structures in Cass Bay and Cosair Bay

Reference:

18/1061830

Presenter(s):

Paula Smith, Chairperson

 

 

1.   Purpose of Report

1.1       The purpose of this report is for the Banks Peninsula Water Management Zone Joint Committee to discuss concerns about fish passage with three stormwater structures in Cass Bay and Cosair Bay.

2.   Staff Recommendations

That the Banks Peninsula Water Management Zone Joint Committee:

1.         Seek technical advice on fish passage for the three new stormwater structures in Cass Bay and Cosair Bay.

3.   Report

At the Banks Peninsula Water Management Zone Committee meeting on 21 August 2018 at Te Whare Tapere o Te Mata Hapuku, Birdlings Flat, the following recommendation was passed:

 

That the Banks Peninsula Water Management Zone Joint Committee:

·      Request staff from Environment Canterbury and the City Council to advise how the Committee could find where barriers to fish passage are located on Banks Peninsula, so the Committee can work with agencies and landowners to eliminate barriers where possible and provide alternative mechanisms, so the many indigenous diandromous fish species inhabiting our streams can complete their life cycle and enjoy breeding success.

This recommendation was agreed to help progress Action 14 in the Zone Committee 3 Year Action Plan.

 

Over the last year or so two new stormwater structures have been built at Cass Bay and another in Corsair Bay. They can be seen adjacent to the inner harbour road and were designed to take water from streams coming down the hills under the main arterial road.

 

At Corsair Bay the stream remains below ground for the rest of its length until it meets the sea at Corsair Bay beach. At Cass Bay the two streams flow through the subdivision, sometimes at the surface and sometimes underground, to meet the sea at the Cass Bay beach.  All three streams are ephemeral which means they usually dry up during mid-summer, except after rain.

 

I emailed the Fish Passage Advisory Group to find out if such structures presented a barrier to fish migration. I did not get a direct response, but my email was forwarded to the Area Supervisor Land Drainage (Banks Peninsula) Tim Ayres who wrote back saying the structures were built to both protect surrounding homes and property from flooding caused by the pipe inlets blocking, and also to ensure the public's safety by inhibiting entry into the pipes. He also advised fish passage was considered as part of the Environmental Management Planning stage of the design. However, as the streams are dry for a large proportion of the year, including fish passage in the design was considered unnecessary.

 

At the recent Nature Agents day where Lyttelton Primary School came to survey Morgans Gully Stream in Diamond Harbour I took the opportunity to ask EOS Aquatic Ecology Scientist Nick Hempston whether native fish lived in ephemeral streams. He made two comments:

 

(a)    fish migrate at the time of year when the streams are likely to be flowing, and

(b)   if there are pools upstream which do not dry up, then it is possible for fish to survive and breed in ephemeral streams.

 

It should be noted that:

·      Banded kokopu (Galaxias fasciatus), which are very good climbers, have been observed in Cass Bay Stream.

·     The upper reaches of similar steep south-facing catchments nearby, those of Whakaraupo Stream and Te Awaparahi Stream, are ranked in the top 10% of regional river rankings in the FENZ (Freshwater Ecosystems of New Zealand) database.

·   Inaka (Galaxias maculata) have been recorded from at least one of Lyttelton's steep streams.

 

The inference I make from the information received is that the three new structures ARE barriers which potentially have the effect of limiting migration and breeding of native fish. An assumption was made by the designers that, because the streams are ephemeral, fish passage was not required. This assumption may not have been valid for these catchments. If the Zone Committee shares my concern, then perhaps the Zone Committee could ask for some technical advice about this matter.

1.   Purpose of Report

1.1       The purpose of this report is for the Banks Peninsula Water Management Zone Joint Committee to provide feedback on the proposed water efficiency campaign for Banks Peninsula over the 2018/2019 summer.

2.   Staff Recommendations

That the Banks Peninsula Water Management Zone Joint Committee:

1.         Support the proposed campaign and communication strategy.

2.         Provide feedback on tactics to effectively communicate the key messages to Banks Peninsula communities.

3.   Report

This paper relates to Action 10 in the Zone committee 3-year Action Plan:

 

Action 10: Promote water efficiency and provide advice to ensure people understand how they can be more efficient and the reasons why water efficiency is important.

Contributors: landowners, CCC, ECan

ZC Role: Provide advice on an effective communication approach to engage community and share messages through networks. Consider public opportunities/events to promote messaging over summer.

 

To support the implementation of Action 10 in the Zone Committee Action plan, Environment Canterbury and Christchurch City Council (CCC) will undertake co-ordinated communications about water efficiency in Banks Peninsula over the 2018/2019 summer. 

 

Environment Canterbury propose to undertake some targeted water efficiency communications on Banks Peninsula using the proposed key message is “Leave enough for the eels (this summer)”. This campaign aims to inform people about the unique hydrology of Banks Peninsula, the importance of keeping water in local streams, and simple ways people can reduce water use. The campaign could be launched with an article from the zone committee chair in December and supported each week with advertisements about practical tips for reducing water use. These could be printed in local papers (e.g. Bay Harbour News and Akaroa Mail) and posted on the Canterbury Water Facebook page. A link to further information on Environment Canterbury webpage will be created which will include the Chairs article and the article from Gina Waibl on ‘permitted takes from springs’.

 

To complement these communications, CCC will also undertake some water efficiency communications. In previous years CCC has run a water conservation campaign with a specific focus on Banks Peninsula, however this year’s campaign is going to focus mainly on the urban area of Christchurch city.

 

Water conservation in the city may also support work towards the removal of temporary chlorination from the network. Saving water is essential in Christchurch city this summer as high water use means CCC will need to rely on all well heads in its system to ensure it can keep up with demand. This means that they can not shut any well heads down to upgrade them. This will slow the programme down and risks the Council not meeting the 12 month deadline for temporary chlorination. If summer demand reaches anywhere near last year’s peak of 250,000 m3/day, not only will water restrictions need to be introduced, but full use of chlorinated bores will be required.

 

Planning is underway on the specifics of the water conservation campaign, however it is anticipated that some of the wider generic water conservation messages will be applicable to Banks Peninsula.
