FREQUENTLY ASKED QUESTIONS (FAQS)

TAKUTAI KĀPITI PROJECT

1) What is Takutai Kāpiti?

Takutai Kāpiti is the project name for a community-led coastal adaptation process for managing coastal change in our district.

The name Takutai Kāpiti was given to us by Council Kaumatua Koro Don Te Maipi, Te Ātiawa. Takutai is translated as sea coast, shore in te reo. The overarching meaning of Takutai Kāpiti reflects our coast, our shorelines, our Kāpiti Coast.

Takutai Kāpiti: Climate Change and Our Coast Summit was held at Ngā Purapura, Ōtaki on Sunday 8 March 2020 to launch the project. The summit conference consisted of presentations from national and local leaders and climate experts on climate change, coastal adaptation and building resilient communities. The speakers’ tent at the community event had a range of kōrero from community groups such as Energise Ōtaki, Low Carbon Kāpiti, Climate Change Action Group, individuals, and Kāpiti Coast District Council.

More information on the summit can be found here.

More information on the summit speakers can be found here.

2) Has iwi been involved in Takutai Kāpiti?

Yes, tangata whenua are involved in the Takutai Kāpiti project.  We are committed to iwi partnership, to ensure the collective environmental vision, values and position inherited and held by the iwi of Kāpiti are woven through the project. We will continue to work with mandated representatives as we shape the process going forward.

More information on tangata whenua can be found here.

3) How will the community be involved in the Takutai Kāpiti project?

Although there are multiple ways that the community can be involved in the Takutai Kāpiti project, the main will be as a volunteer in the Community Assessment Panel.

Phase Two of the Takutai Kāpiti project involves the establishment of a Community Assessment Panel in 2021. The CAP will be a working group of local people and the formal mechanism through which the wider community input, iwi and technical expertise are used to develop the medium to long-term adaptive solutions.

The Community Assessment Panel will meet regularly over a 12-month period to consider the coastal hazards and risks they represent, review a range of adaptation options, and assess cultural, social and economic impacts.

At the end of the process, the Community Assessment Panel will recommend coastal adaptation options for Council’s consideration. The recommendations should guide development of District Plan provisions to manage coastal issues and an approach for the district dealing with coastal hazards.

The wider community will be able to feed into the process in less formal ways, this will include utilising the dedicated Takutai Kāpiti website, surveys, and public open days.

4) Has this type of coastal adaptation project been done before?

Numerous coastal adaptation projects have occurred internationally and nationally.

Two examples include the Hawke’s Bay Clifton to Tongoio Coastal Hazard Strategy 2120 and the Makara Beach project in Wellington. We will draw upon these projects and looking at other emerging best practice to learn and develop our approach for Kāpiti. More information about these projects are available on our  Resources page.

5) What does the success of the Takutai Kāpiti project look like?

At the end of the Takutai Kāpiti project, we’ll have a sustainable and flexible 100-year coastal adaptation strategy for the Kāpiti Coast District that is support by sound technical expertise, and reflects the values and aspirations of tangata whenua and our community.

6) Why is the Takutai Kāpiti project focusing on adaptation and not mitigation?

Mitigation and adaptation are the two approaches for addressing climate change issues. We need both however, the focus of this project is about resilience and adapting to change.

Mitigation is an intervention to reduce emissions or enhance the sinks of greenhouse gases. It is about reducing the scale of climate change and requires global level influence

Adaptation is an adjustment in natural or human systems in response to actual or expected climatic change or its effects, which moderates harm or raises beneficial opportunities.

It is the approach taken in coastal and low lying areas to reduce vulnerability and increase resilience on a local scale. The aim is to build resilience so the impact is less.

We need both however, the focus of the Takutai Kāpiti project is about building resilience and adapting to change along our coast. How we adapt to change, and the impacts of sea level rise is our opportunity to help prepare future generations.

7) What are the cost implications for the Takutai Kāpiti project?

A key part of the Community Assessment Panel process is considering a range of adaptation options informed by technical expertise, cultural impact, social impact and economic impact assessments. Options and decisions will be considered on the basis of all these impacts. Cost modelling will be undertaken as part of this stage of the process.

8) Is it too late to make a difference to what happens on the Kāpiti Coast?

While we don’t know how significant these changes will be and how quickly they will happen, we do know that communities which plan for change, and work together, are more resilient in the face of that change.

It is important that we are dealing with the social and environmental challenges facing us, including climate change impacts.

Adapting to climate change along with ongoing development pressures on our coast will be an ongoing challenge into the future.

People within our coastal communities will need to:

  • become more aware of climate change effects;
  • consider how they become more resilient to the potential impacts of climate change.

Climate change and impacts from sea level rise will vary along the coastline and decision-makers face unavoidable uncertainty.

It is not possible, practical or sensible to wait until uncertainties are reduced before starting to consider what options might be preferred by the community.

KĀPITI COAST COASTAL HAZARDS

1) Why does Kāpiti need to prepare for the impacts of climate change and coastal hazards?

In May 2019 Council declared a climate emergency on the Kāpiti Coast. This is political recognition of the need for action in reducing our emissions, as well as the risks our communities are facing now, and will increasingly face over the coming decades, from coastal erosion, rising ground water and increased storm events.

In June 2019 a coastal vulnerability assessment ‘Preparing coastal communities for climate change’ by Mitchell Daysh and Dr Iain Dawe was released. This report was commissioned alongside our regional partners. Its purpose was to prioritise where to focus efforts across the region. A link to this report is available here.

Numerous studies have been undertaken, describing the coastal environment and dynamics along the Kāpiti Coast. These studies alongside smaller more focused projects or investigations are catalogued in Our Coastal Bibliography which can be found here.

Greater Wellington Regional Council has developed a Sea Level Rise Mapping Tool. This tool helps tell the story of what sea level rise might look like above the high tide mark around the Wellington Region. Use this tool to identify what areas will get wet first and see what an extreme sea rise will do to our region. You can find the tool here.

2) Are there any statutory and legislative requirements to deal with climate change and coastal hazards?

There are statutory and legislative requirements for Councils to manage the risks from coastal hazards and the effects of climate change. An important document is the New Zealand Coastal Policy Statement 2010 (Objective 5 and Policies 24-27) which directs councils to identify areas that may potentially be affected by coastal hazards over a timeframe of at least 100 years.

3) Why were the coastal hazard provisions withdrawn from the Kāpiti Proposed District Plan?

As a result of community and submitter concerns surrounding a number of the Proposed District Plan (PDP) provisions relating to coastal hazard provisions, Council commissioned two independent reviews of the PDP in November 2013. An independent Coastal Hazard review panel was also established.

On 24 June 2014 the Council received the two reports entitled ‘Coastal Erosion Hazard Assessment for the Kāpiti Coast: Review of the Science & Assessment Undertaken for the Proposed Kāpiti Coast District Plan’ and ‘Independent Review of the Kāpiti Coast Proposed District Plan’. The key findings of the Independent Coastal Hazard review panel was:

“The opinion of the Panel based on its review is that the existing recommended hazard lines are not sufficiently robust for incorporation into the Proposed District Plan. However, there are components of the analyses undertaken by Lumsden and Coastal Systems Limited, which if updated and combined could potentially yield scientifically–sound, best practice hazard lines for the Kāpiti Coast.”

The report then presented a series of further technical recommendations to improve the scientific evidence to quantify the coastal hazard risks posed to the Kāpiti coastline.

Sylvia Allan, in the ‘Independent Review of the Kāpiti Coast Proposed District Plan’, recommended the formal withdrawal of the coastal hazard provisions of the PDP.

4) Will there eventually be updated coastal hazard provisions in the future District Plan?

Yes, but the nature of those provisions will not be decided until the Takutai Kāpiti project has been completed. It is too early to say what such provisions could look like.

5) What coastal hazard rules apply?

Coastal hazards continue to be addressed by the Operative District Plan while the coastal hazards research continues.

The list of Operative District Plan provisions which continue to apply until replaced via future RMA Schedule 1 process can be found here: https://www.kapiticoast.govt.nz/media/28341/public-notice-withdrawal-of-coastal-hazard-provisions-from-pdp-23-oct-2016.pdf

KĀPITI COAST DISTRICT COUNCIL 

1) What else is Kāpiti Coast District Council doing about climate change?

In regards to reducing its own emissions, KCDC has been a leader in the local government sector in New Zealand in mitigation action. By the 2018/19 financial, KCDC had reduced in-house carbon emissions from 12,498 tCO2e (2009/10 baseline year) to 2,868 tonnes CO2e – that is a 77% reduction.  When we joined the scheme we set a very ambitious target to achieve an 80% reduction in emissions by 2021/22.

Additionally, council supports regional and national projects and campaigns such as;

  1. Zero Waste Education Programme;
  2. Enviroschools;
  3. Paper4Trees;
  4. Love Food Hate Waste;
  5. Green Parenting Workshops;
  6. Seaweek;
  7. Plastic Free July.

2) Which seawalls are owned and maintained by council and why?

Council build and maintain multiple seawalls (or hard protective structures) along the Kāpiti coast for the purpose of protecting council infrastructure and areas of importance such as ecological sites. A large scale example is the Paekākāriki seawall. It is not Council policy to build seawalls for the purpose of protecting private property.

3) Does this work impact the progression of the seawall in Paekakariki?

The Paekakariki sea wall project is a major project in the 2018 Long Term Plan and is aimed at protecting council roading infrastructure. It has gone through all the relevant approval processes (Greater Wellington Regional Council Consent, Building Consent, six years of community consultation and Council approval). The final design and resource consent has been approved, and there is tendering for physical works in 2020/21 financial year.

4) What are councils flood models?

The current suite of flood models were built in 2010-2012 (based on models developed for KCDC by Jacobs (then SKM) between 2006 and 2009) – the flood extent and recommended build levels are for the 1 in 100 year event with predicted 2090 mid-range impacts of climate change rainfall [16%], 0.8m sea level rise and 1 in 20 year tides.

The 1 in 100 year maps also have a dynamic freeboard applied, with 0.5m applied to flooding with open channels and 0.3m applied to discharges from Council’s network.  Freeboard takes into account uncertainties from a variety of sources, which may be relevant to this location:

  • Data limitations and modelling approximations;
    • Storm runoffs are derived based on assumptions as to rainfall patterns, ground soakage and saturation
    • Assumptions as to ground and channel roughness
  • Physical considerations;
    • Wave action caused by wind or motor vehicles
  • Effect of obstruction on flows
  • House construction limitations
  • Water ponding within 100 to 150mm of a slab or timber framed floor over any length of time can be absorbed into the structure causing damage to carpets, cladding, etc.

5) Is Kāpiti Coast District Council going to upgrade their flood models?

The tender looking for a consultant to re-build new flood models closed at the end of February 2020.  The models will be updated to include recent development which has occurred within the District.  There are also, now, opportunities to improve the models by taking advantage of updated software capability, improved computing power, improved topographic data [LiDAR] and improved information on the drainage network, updated climate change predictions, and to merge model catchments as appropriate.

OFFICIAL INFORMATION REQUESTS – PROACTIVE RELEASE 

OFFICIAL INFORMATION REQUESTS 

2019

1) Are the dunes along the Peka Peka beach accreting?

My colleague Dr Dawe at Greater Wellington Regional Council has provided the following response to your query regarding dune accretion along the Peka Peka coastline.

Historically the coast has been accreting, but in the last few decades this trend has slowed and since the mid-1990s has been relatively stable, neither accreting or eroding, but rather in a state of dynamic equilibrium. What this means is that from time to time, storm events will cause erosion to the beach and the dunes will be cut and in the ensuing months it will repair itself back to the pre-storm state. Recent years have seen increasing periods of storm cut, with the beach taking longer to regain its non-eroded state.

This is to be expected under a rising sea level which allows waves to reach higher up the beach and cause more intense storm damage. Over time the beach will want to move landward as it adjusts to this changing water level regime. So whilst the beach has accreted historically, there are signs that this has slowed to a dynamic equilibrium and may reverse to an eroding phase due to the effects of sea level rise.

GWRC have an interactive online sea level rise mapping tool that shows areas susceptible to impacts from sea level rise under different scenarios. This same tool also presents storm surge modelling that highlights areas vulnerable to current and future flooding from coastal storm events: https://mapping1.gw.govt.nz/GW/SLR/.

  • Released November 06 2019

2) What dune restoration work is planned for Peka Peka?

Kāpiti Coast District Council supports dune restoration by collaborating with Greater Wellington Regional Council in a programme of environmental weed control and strategic planting of native dune species. The programme covers the dune reserve between Te Kowhai Stream north of Peka Peka and Pharazyn Reserve to the south. Its purpose is to protect and enhance the sand dune ecosystem. As part of the programme, specialised contractors are engaged each year to control invasive exotic weeds such as marram grass and boxthorn. During this year’s winter planting season, the native sand binding plant spinifex was planted along the front of the foredune to bolster natural recovery from erosion caused by storms during the last three years.

In addition to supporting this programme, Kāpiti Coast District Council supports the Peka Peka Dune Restoration Group, based in Marram Way. If you are interested in helping this group, please contact Brenda Smith at smith.barrett@xtra.co.nz

3) What is the GIS data of sea-level rise scenarios (0.5-3m) used by the Council?

“What is the GIS data of sea-level rise scenarios (0.5-3m) used by the council and GIS data or any other format used by the council to analyse the impact of sea-level rise on local infrastructure (three waters, buildings/facilities, transport, landfills, green spaces, as defined by the Vulnerable report)?”

The most up to date sea-level rise scenarios are held by Greater Wellington Regional Council. A Sea Level Rise Tool has been developed by Greater Wellington Regional Council. For reference, this can be found at https://mapping1.gw.govt.nz/GW/SLR/

With regard to the report: Greater Wellington Regional Council – Preparing Coastal Communities for Climate Change: Wellington Regional Coastal Vulnerability Assessment 2019, LGNZ provided baseline GIS parameters and in turn Kāpiti Coast District Council provided LGNZ with information on the assets within those parameters. This report is also available on our resources page.

4) What is the estimate of the rate of current sea level rise on the coast and projected rate of future sea level rise?

“Can you please tell me your best estimate of the rate of current sea level rise on the coast, and projected rate of future sea level rise on the coast. I have read that you rely on the current rates indicated at Wellington harbour for the best estimate of current sea level rise rate, but also the mean sea level rise over the past century for the earth (1.7mm/yr). Additionally, that you rely on the guidance of MFE for future projections?”

Kāpiti Coast District Council (KCDC) relies on NIWA’s calculations of the current rate of relative sea level rise for the Wellington region for local planning purposes.  NIWA have calculated this as 2.23 mm/yr, compared to the general global rate of 1.8 mm/yr. (Please refer to NIWA: Update on relative sea-level rise and vertical land motion: Wellington region).  The relative regional rate is measured from local tide gauges dating back to 1891 and takes into account both global eustatic[1] sea level rise and local vertical land changes as a result of local plate tectonics.

KCDC also relies on Ministry for the Environment’s Coastal Hazards and Climate Change – Guidance for Local Government to guide future projections for coastal areas in New Zealand.  This document takes into account local rates of sea level rise measured from around New Zealand.

5) What are the short and long term erosion trends of erosion on the Kāpiti Coast?

“looking through your summary of the information base, you note that the coast is eroding in the south of the Kāpiti region but is accreting in the north. What is the evidence for the latter as my memory from Ōtaki about 10 years ago was that the dunes just south of the waitohu stream were eroding?”

Short term and long term erosion:

There are two types of erosion that beaches and dunes can experience – short term and long term. All beaches experience short term erosion associated with storm events that cause a loss of sand from the beach and leaves features like scarps and cuts to dunes. At a place like Waitohu Beach, where a stream comes out, there are additional effects from the stream cutting the beach and dunes during flood events. These events are dramatic and happen quickly – in a matter of hours or days.

Long term accretion:

A beach that is stable or accreting in long term, will recover from short term erosion (storm events) and over time the events average out and the shoreline continues to grow. This happens gradually and incrementally over a period of months to years. This is what happens in beaches along the northern part of the district. On average, there is more sand being accumulated on the beach than is being lost and the shoreline builds out or remains stable.

 Accretion and erosion are not fixed processes and can change over time:

Beaches that are currently stable or accreting (on average) may change into a phase of net long term erosion, as sea level rises and adds pressure on the beach to respond to storm events. Beaches that are currently in a phase of long term erosion will experience an enhanced rate of retreat.

In the case of a beach experiencing long term erosion you still get these short term erosion events, but in addition there is a long term pattern of retreat with more sand being lost from the beach than is being added ie, the beach has a sand deficit and is unable to fully recover in-between the storm events and it ends up in net long term erosion.

Waitohu stream area:

While shorter term effects on the beach from storm and flood events mean that erosion is very much part of the conversation in that area, the long term trend is that the coastline has been building out or accreting. Bear in mind that the processes in this area may change and the recent past is not necessarily a guide to what will happen in the future.

6) How has coastal erosion affected the people on the Kāpiti Coast?

“I am a year 9 at Kāpiti College. I am doing a project at school on the erosion and I was wondering if you had any information or any photos that I can have a look at. The main purpose of my project is to understand how erosion is, has, and will affect the people on the Kāpiti Coast. If you had any photos or maps that would be great to have a look at, or any information about how its affected people. Such as coastal erosion zone maps, restrictions and impacts. Any historical photos that show the difference would also be awesome.”

For ease of reading, the request has been split into four sections to be answered.

  1. Erosion;
  2. How erosion is, has, and will affect the people on the Kāpiti Coast;
  3. Coastal erosion zone maps, restrictions and impacts;
  4. Any photos or maps, including Historical photos of the coast line.

A lot of the information referred to can be found through publicly available council websites, so the links for these are provided rather than attaching documents to this response.

Erosion

 Firstly, for the purpose of clarity an outline of the processes of erosion and accretion have been added below.

  • Short term and long term erosion

There are two types of erosion that beaches and dunes can experience – short term and long term. All beaches experience short term erosion associated with storm events that cause a loss of sand from the beach and leaves features like scarps and cuts in dunes. At places where a stream comes out, there are additional effects from the stream cutting the beach and dunes during flood events. These events can be dramatic and happen quickly – in a matter of hours or days.

In the case of a beach experiencing long term erosion, you still get these short term erosion events, but in addition there is a long term pattern of retreat. This results in more sand being lost from the beach than is being added i.e., the beach has a sand deficit and is unable to fully recover in-between the storm events and it ends up in net long term erosion. This long term erosion phase is present at the southern end of the Kāpiti Coast (Paekākāriki, QEII Park and Raumati South).

  • Long term accretion

A beach that is stable or accreting in long-term, will recover from short-term erosion (storm events) and over time the events average out and the shoreline continues to grow. This happens gradually and incrementally over a period of months to years. This is what happens in beaches along the northern part of the district. On average, there is more sand being accumulated on the beach than is being lost and the shoreline builds out or remains stable.

  • Accretion and erosion are not fixed processes and can change over time

 Beaches that are currently stable or accreting (on average) may change into a phase of net long term erosion, as sea level rises and adds pressure on the beach to respond to storm events. Beaches that are currently in a phase of long term erosion will experience an enhanced rate of retreat.

How erosion is, has, and will affect the people on the Kāpiti Coast.

Below are a few examples of storm events that have caused erosion on the Kāpiti Coast:

Short term erosion in 1976 caused significant damage to the Kāpiti Coast line and private property. It also damaged council assets such as carparks, storm water drains and other infrastructure. Council has a series of aerial photographs of the coastline at this time. The full series of photos can be shown to you once the council building reopens, however I have included some of these images for your reference, in this response.

The photo below was taken in 1976 as a series of images to assess the damage and is of 36-50 Marine Parade, Paraparaumu.

A storm in 2003 was another event that caused short term erosion along the coast line effecting private property and council assets. Council took another series of photos of the coast at this time.

This photo is of 45-55 Marine Parade, Paraparaumu and was taken in 2003:

A storm in 2016 caused erosion to the dunes and properties at the southern end of Marine parade. This erosion threatened a sewer main and required immediate mitigation work to protect this infrastructure and the people who live near to it. The link below is a council announcement about this work.

https://www.kapiticoast.govt.nz/whats-on/news/2016/temporary-protection-put-in-place-on-beach/

Below is a photograph of the Wharemauku sea wall taken in August 2019 after the mitigation work was completed:

Looking forward at the potential future effects of coastal erosion, it is likely that continued short and long term erosion will continue to impact people on Kāpiti Coast. As mentioned above, there is a current trend of long-term erosion at the southern end of the Kāpiti Coast. With climate change and sea-level rise added to the mix, it is likely that this trend of erosion will continue into the future.

Coastal erosion zone maps, restrictions and impacts?

The Council is currently in a transition period, moving from the Operative District Plan (ODP) to the new, Proposed District Plan (PDP). While most rules/restrictions for the district now come from the PDP, many of the rules around coastal development are still taken from the ODP.

Chapter 9 of the ODP has rules and standards that relate to the coastal environment. An example of one rule in the ODP that restricts some coastal properties in Paekākāriki and Raumati South is beach setback lines. These line restrict where a new house can be built on beach front properties (essentially requiring them to be built 20m back from the coastal property boundary). Links to the full district plans are below.

Any photos or maps, including Historical photos of the coast line?

We have plenty of information including photos related to coastal erosion in the Kāpiti district and are happy to share them with you. As many of these are large files or in some cases not electronic, once the COVID-19 lock down restrictions are lifted we can arrange for you to come into the Council offices to view these. We would also be happy to organise a site visit so that you can see the coastal erosion impact on properties and public infrastructure (roads, water/wastewater/stormwater assets, footpaths etc.) for yourself.

There are many useful resources you can access from home for example the council GIS mapping tool found though the link below, as well as the Takutai Kāpiti website which has a catalogue of reports relevant to coastal processes on the Kāpiti coast. Both the science page and the resources page have information that will help inform you on erosion.

7) What is KCDC's budget for coastal hazards for the 2020/21 financial year?

What are the current proposals compared with the original draft?

On 30 April 2020 Council considered its budget and Annual Plan for the 2020/21 financial year in light of Covid-19 and expected economic conditions. I can confirm, that no reduction to the Coastal budget was made as a result.

How were these figures derived?

The budget for the Community-led coastal adaptation project was established through the scoping and planning of this project. The budget was based on the anticipated costs of the following key aspects of the project:

  • Establishment and operation of Community Assessment Panels
  • Community Assessment Panel expenses of External resources: Technical advisors, panel facilitator(s)
  • External assessments: Cultural values, social impact, economic impact assessments
  • Comms and engagement with the wider community on the project

These costs may be impacted by recommendations made by the co-design working group, including the number of Community Assessment Panel(s) for the project.

What does this mean for the timeline for KCDC?

The timeline for the Community-led coastal adaptation project has not changed. Work is still progressing in line with the project milestones attached to the Terms of Reference for the codesign working group.

Ways the community could alleviate the constrictions of a reduced budget.

As noted above, the budget for this project has not been reduced.

Analysis of risks.

Risks or issues are assessed and managed by the project team for the duration of the project, including risks relating to the project budget.

8) How does erosion/ climate change impact the Kāpiti Coast natural environment?

Question 1: How does erosion/ climate change impact the Kāpiti Coast natural environment?

The Kāpiti coastline is approximately 40km long. As well as being the location for significant urban development, our beautiful beaches are an important community asset with many unique characteristics and natural qualities. Like many coastal communities around Aotearoa, Kāpiti is facing significant environmental challenges from our changing climate and associated rising sea and groundwater levels.

In May 2019 Council declared a climate emergency on the Kāpiti Coast. This is political recognition of the need for action in reducing our emissions, as well as the risks our communities are facing now, and will increasingly face over the coming decades, from coastal erosion, rising ground water and increased storm events.

In June 2019 a coastal vulnerability assessment ‘Preparing coastal communities for climate change’ by Mitchell Daysh and Dr Iain Dawe was released. This report was commissioned alongside our regional partners. Its purpose was to prioritise where to focus efforts across the region. A link to this report is available here.

Numerous studies have been undertaken, describing the coastal environment and dynamics along the Kāpiti Coast. These studies alongside smaller more focused projects or investigations are catalogued in Our Coastal Bibliography which can be found here.

Greater Wellington Regional Council has developed a Sea Level Rise Mapping Tool. This tool helps tell the story of what sea level rise might look like above the high tide mark around the Wellington Region. Use this tool to identify what areas will get wet first and see what an extreme sea rise will do to our region. You can find the tool here.

 

 Question 2: How does this impact people within this location?

While we don’t know how significant these changes will be and how quickly they will happen in Kāpiti, we do know that communities which plan for change, and work together, are more resilient in the face of that change.

It is important that we are dealing with the social and environmental challenges facing us, including climate change impacts.

Adapting to climate change along with ongoing development pressures on our coasts will be an ongoing challenge into the future.

People within our coastal communities will need to:

  • become more aware of climate change effects;
  • consider how they become more resilient to the potential impacts of climate change.

Climate change and impacts from sea level rise will vary along the coastline and decision-makers face unavoidable uncertainty.

It is not possible, practical or sensible to wait until uncertainties are reduced before starting to consider what options might be preferred by the community.

Question 3: What is being done about erosion/climate change along this Coast?

Mitigation Vs. Adaptation

Mitigation and adaptation are the two approaches for addressing climate change issues. We need both however, the focus of this project is about resilience and adapting to change.

Mitigation is an intervention to reduce emissions or enhance the sinks of greenhouse gases. It is about reducing the scale of climate change and requires global level influence

Adaptation is an adjustment in natural or human systems in response to actual or expected climatic change or its effects, which moderates harm or raises beneficial opportunities.

It is the approach taken in coastal and low lying areas to reduce vulnerability and increase resilience on a local scale. The aim is to build resilience so the impact is less.

We need both however, the focus of the Takutai Kāpiti project is about building resilience and adapting to change along our coast. How we adapt to change, and the impacts of sea level rise is our opportunity to help prepare future generations.

ADAPTATION:

The Takutai Kāpiti: Our community-led coastal adaptation project.

On 8 March 2020 the Takutai Kāpiti: Climate Change and Our Coast Summit 2020 launched the Takutai Kāpiti: Our community-led coastal adaptation project

 The Takutai Kāpiti project is a community-led collaborative process working in partnership with local iwi and supported by Kāpiti Coast District Council. The project aims to encourage our Kāpiti Community to become more aware of the impacts of climate change and sea-level rise and empower them to take part in developing solutions and pathways for adapting to coming change. This will be through the establishment of a Community Assessment Panel (CAP) in 2021 consisting of iwi, community and other key stakeholder / agency representatives to consider our district’s response to the impacts of climate change on the coast.. The CAP will have access to technical advice to inform their decision making which will include the social, economic and cultural impact that coastal hazards impose on the Kāpiti community. These reports will be published on the Takutai Kāpiti website.

The Takutai Kāpiti project will follow the Ministry for the Environment’s Coastal Hazards and Climate Change Guidance for Local Government[1] and take advice and lessons learnt from the  Clifton to Tongoio Coastal Hazards Strategy 2120[2] and The Makara Beach Project[3]. The recommendations from the Ministry for the Environment is to work with communities to enable them to map out a range of adaptation solutions, based on a range of scenarios, over a 100-year period.

The outcomes for the Takutai Kāpiti project will include a range of adaptation and management options for Kāpiti, and will likely identify the areas that may be affected by various coastal hazards over the long term and the risks to public and private property, cultural sites and areas, recreational use and infrastructure services.

MITIGATION:

In regards to reducing its own emissions, Kāpiti Coast District Council has been a leader in the local government sector in New Zealand in mitigation action. By the 2018/19 financial, KCDC had reduced in-house carbon emissions from 12,498 tCO2e (2009/10 baseline year) to 2,868 tonnes CO2e – that is a 77% reduction.  When we joined the scheme we set a very ambitious target to achieve an 80% reduction in emissions by 2021/22.

Additionally, council supports regional and national projects and campaigns such as;

  • Zero Waste Education Programme;
  • Enviroschools;
  • Paper4Trees;
  • Love Food Hate Waste;
  • Green Parenting Workshops;
  • Seaweek;
  •     Plastic Free July.

Question 4: What do different people think about erosion/climate change along this Coast?

At the Takutai Kāpiti: Climate Change and our Coast summit 2020 we received the following feedback from the community:

SUMMIT FEEDBACK: TELL US WHAT YOU THINK

  1. What do you value about our coastline?
  • Accreting
  • Biodiversity and recreation
  • Wide-open, natural, shorebirds
  • It defines Kāpiti and who we are as a community
  • Clean, clear water
  • Sense of place, connection with ocean. Peace
  • Swimming every day in the moana – clean, safe, refreshing!
  • Biking and walking along beach and coastline most days!
  • View of beautiful, powerful Kāpiti island
  • Clean water and, riparian vegetation, low noise/light pollution
  • Takutai Moana Papatuanuku hoki!
  • Kaitiaki Māori are great in our area
  • He Kohinga mātaitai. Hei whāngai i te whanau, marae, hapū, hāpori
  1. How should we protect our coastline?
  • Stop building along coast
  • Shift away from hard barriers and engineered solutions – accept what is happening and seek to work with it
  • Don’t try to protect – retreat. Change housing stock to be more easily movable. Ensure the poor are not left behind
  • Whakarerea atu te hunga pākihi e tango ana i te nui o ngā kaimoana i te takutai
  • Make wise educated choices on development. Bigger is not always better
  • Tautoko full time kaitiaki on the beach – kaitiakitanga I nga wā katoa!
  • Reduce emissions
  • Dunes
  • Plant coastal vegetation
  • Protective estuaries
  • BEACHES (Don’t sacrifice them for hard defences)
  • Consult and include Māori in all decision making and processes. Utilize Māori connection with place for guidance
  • Get all vehicles off the beach apart from boat launching

 

  1. How do you want to be involved, updated and informed?
  • I’d like to see maps with projections of coastal erosion, sea level rise
  • A range of communication method:

– not everyone has a computer/internet connection/ Facebook e.t.c

– not everyone receives the local newspapers.

  • Pictorial representations
  • Newsletters in lots of different places and displays:

– Doctors, cafes, schools, kindergartens, mechanics…

– Not too wordy

  • Creative comms, e.g. similar to tsunami lines in WGTN for getting attention/making relevant.
  • Full consultation with tangata whenua!
  • Listen to tangata whenua – a direct line of contact is essential so that response to issues (eg. Cloudy bay clams stripping out the mātaitai) can be dealt with immediately.
  • Call us in for some real consultations where our (someone had added: who?) voices are heard. The speeches were interesting but one way only.
  • Call on us if non-violent direct action is needed
  • We need serious and detailed research on potential ground water table rise in Kāpiti and it’s impacts on public and private assets.
  • I’m interested in supporting korero re climate change and taiao with Ngāti Haumia, as Ngāti Haumia, Hēni Colins
  • Protect the kaimoana by keeping the water clean.
  • Proactive/(reactive) maintenance of Raumati seawall.

We hope that this information is helpful to you, if you have any further questions please don’t hesitate to ask.

We would also like to add that the Takutai Kāpiti project is looking to establish a Community Assessment Panel (CAP) in the new year.

Involving rangatahi, our youth in the Takutai Kāpiti project is very important and so if there are any students or teachers that are Kāpiti residents and would like to be involved we would encourage then to apply to be part of the CAP. Applications will be advertised in the new year.
