Helen Rutter, Senior Groundwater Hydrologist for Aqualinc, shared her report and expertise on what the potential impacts of sea level rise and rainfall increases could be on groundwater levels in Christchurch as a city, including coastal and low lying areas within.

Shallow Groundwater in Christchurch- how will sea level rise change it?

Groundwater will play a significant part in the cities response to hazards driven by sea level rise. What are the implications for building?

Helen Rutter, Senior Groundwater Hydrologist for Aqualinc, shared her report and expertise on what the potential impacts of sea level rise and rainfall increases could be on groundwater levels in Christchurch as a city, including coastal and low lying areas within.

 

Groundwater is often “out of sight, out of mind”, when considering risks to our urban areas. However, in many of our coastal areas, there is limited depth to groundwater. Recent monitoring have shown how dynamic groundwater level responses can be, being affected by rainfall, river flow and tides. This means that the combination of these main drivers can cause groundwater to rise to problematic levels; the effects of climate change and sea level rise will add to the existing issues.

Groundwater will play a significant part in the city’s response to hazards driven by sea level rise. What are the implications for building and mitigation? What are the uncertainties and assumptions we keep hearing about?

Helen is a hydrogeological research scientist with 28 years’ expertise. This includes 17 years with the British Geological Survey working on varied hydrogeology projects in the UK and Africa. She has expertise in resource assessment, recharge processes, groundwater flooding, catchment characterisation, geology and geochemistry, and also considerable expertise in the application of GIS techniques to assist in analysing spatial data.

Presentation approx. 1 hour, including Q&A.

Warwick Schaffer chair of CCRU presents - "Coastal Hazards Process - what we know, the gaps and our concerns: Take Two"

This was a chance to hear about what we know of the process, the gaps and concerns but most importantly a chance to ask your questions.

This was a facilitated discussion by CCRU at the invitation of the Sumner Residents Association. It was an opportunity to share and debate concerns and ask questions.

 

The following summarises some of the concerns CCRU gathered from the community both early on and at a recent similar meeting in New Brighton.

Concerns expressed by the community in early 2020:

  • That coastal suburbs are being singled out, picked on, hazards with higher likelihood exist in other areas and building is not being restricted.

  • Extreme scenarios stacked on top of each other coupled with harsh restrictions.

  • That there is a view in council or elements in it that coastal suburbs are doomed and need to be moved along. A view that influences policy development in a way that looks to withdrawal of investment or support rather than adaptability. ‘A sinking lid policy for coastal suburbs’.

  • Use of fast track processes and lack of natural justice.

  • CCC Conflict of interest (in being able to reduce risk via planning tools without direct cost).

  • Lack of community representation and critical voices on the working group

  • The working group behind closed doors, lack of meaningful inclusion

  • Experts are nameless and not available to be questioned.

  • Decisions already made regardless of community suggestion/experts/concerns.

Richard Dalman and Simon Brown present - "Designing on the Coast: Hazards & Consents"

Sponsored by DALMAN ARCHITECTS

If you are thinking about building along the coast, have tried to build, or have successfully built - we encourage you to watch this valuable and informative presentation.

 
Award winning architects Richard Dalman and Simon Brown from Dalman Architects talk about their own challenges encountered in the process of completing their house builds on the Estuary at Redcliffs and South Shore beach front.

 

Simon comments: "The reason for this is that my house is not actually in the HFHMA and just touches into the Flood Management Area (FMA), and so doesn’t quite fit the coastal hazard zones title. My intention is to talk about the specific challenges and opportunities with my house, particularly from a consenting perspective, in addition to some comments about how to approach a build in the Southshore HFHMA and Residential Unit Overlay (RUO)."

They openly discuss how they addressed the constraints and challenges such as building on sand and in a flooding hazard area, respecting and enhancing existing ecosystems, and winning an MBIE Determination against having a hazard notice placed on the Certificate of Title.

Simon Watts Presentation - Adaptation of Coastal Communities: the good, the bad, and the ugly

Simon uses case studies to support his presentation about Best Practice process, how the NZ guidance measures up against this best practice, and along the way discusses the role of scenarios, trigger points, and economics.

 
Simon Francis Watts BSc; PhD; DIC; CChem; FRSC; CEnv; FIEnvSc; MRSNZ


Simon is originally from the UK, and before coming to NZ taught at Oxford Brookes University for many years. With his wife he settled in NZ in 2007.

Gary Teear Presentation - Mitigating coastal hazards and protecting communities

We would like to change the narrative around coastal hazards from negative to finding solutions. There is very little discussion about solutions. Help us change that.

 

Gary Teear from OCEL is talking about coastal engineering solutions and the issues posed by rising seas.

 

Recently, Gary prepared an environmentally sympathetic protection plan for the South Shore Residents Association and is part of the expert group designing and implementing the estuary bund and cycleway.

 

Gary Teear has a wide range of experience, both within New Zealand and internationally, in sub-sea and coastal engineering, marine structures and soil mechanics, piling, sediment movement and dredging. Gary has had a long association with Lyttleton Port.

 

The PPT sideshow that Gary used in the presentation is available on request.
