1.   Purpose of Report

1.1       The purpose of this report is to update the Infrastructure, Transport and Environment Committee on the development of a multi-hazard assessment approach to decision making on floodplain management for 'flat land' areas of Christchurch.  Decisions on floodplain management will directly influence the implementation of the Land Drainage Recovery Programme (LDRP).  The scope of the LDRP will be broadened to allow investigations into other hazards and will enable a broader assessment of risks from those hazards.

 

2.   Staff Recommendations

That the Infrastructure, Transport and Environment Committee:

1.         Receive the information in this report.

 

 

3.   Key Points

3.1       This report details progress towards investigations into a multi-hazard assessment approach that considers a wide range of hazards and their interactions to inform decision making on floodplain management in a particular locality.

3.1.1   A multi-hazard assessment approach for long term planning and informing decision-making on future infrastructure planning and construction is proposed.  This approach would consider a range of hazards holistically and promote effective, long term sustainable interventions to reduce risk to the community.

3.1.2   The approach will be used to answer the question: How do we make a decision on flood management in a multi-hazard environment?  A multi-hazard assessment of flood defence, and other management options will help to inform decision making on the most appropriate way to manage floodplains, now and in the future.

3.1.3   The following natural hazards are proposed to be considered:

Table 1 'Flat Land' Hazard Descriptions

Hazard group

Hazard type

Description

Earthquake

Ground shaking

Ground shaking is caused by the sudden release of energy from an earthquake.  The intensity of ground shaking depends on the energy of the earthquake, the distance from the source and the local geology.

Liquefaction

Liquefaction occurs when saturated sediments, such as sand and silt, are shaken to the point that they behave like a liquid.  Liquefaction causes ground deformation (lateral spreading, cracking and surface buckling), subsidence, deposition of sediment and flooding.

Land movement

Permanent vertical and horizontal movement of the land surface during an earthquake is caused by movement on faults and the displacement of parts of the earth’s crust.

Flooding

Regional (Fluvial)

A flood occurs when the amount of water in a river exceeds the capacity of the river channel and protection works (such as stopbanks) and inundates adjacent land.  The Waimakariri River is Christchurch's only regional flood source.  Existing flood protection works on the Waimakariri River have the capacity to contain flood flows of 6,500 m3/s - a one in 10,000 year event.

Flooding

Coastal

Local (Fluvial)

Local rivers are the main source of local flooding in Christchurch.  Long duration and/or high intensity rainstorm events cause these rivers and their tributaries to flood.

Network / Surface (Pluvial)

Pluvial flooding results from localised intense rain exceeding stormwater network capacity and is often associated with thunderstorms.  This is flooding that occurs in the system upstream of the local and regional rivers.

Groundwater

Groundwater near to, or at, surface level can cause long term land use issues.

Inundation

Coastal inundation or flooding normally occurs when there is a temporary increase in sea level due to low pressure weather systems.  These 'storm surges' can have extreme flooding effects when combined with a high tide.

Coastal

Erosion

Coastal erosion is the retreat of the shoreline caused by currents, waves and the wind.  Most coastal erosion occurs in large increments during storms when heavy swells buffet the coast.  Rising sea-level contributes to coastal erosion by allowing storm events to encroach further inland.

Tsunami

Tsunamis are an increase in the sea-level caused by the rapid displacement of a large volume of water.  Christchurch is subject to distant (generated more than three hours travel time from NZ), regional (one to three hours) and local (less than one hour) source tsunami.

 

3.1.4   The advantages of a multi-hazard approach include:

·     A fuller understanding of hazard exposure and consequences, providing a better understanding of total risk and greater clarity to the community regarding long term planning and intervention decisions

·     Greater transparency and robustness in decision making and less chance of regretting decisions made

·     A reduction in risk to the community from natural hazards

·     Improved response capability based on realistic scenarios

·     Planning and development decisions are appropriate for both current and future generations

·     Developing effective, long term and sustainable interventions is a prudent and responsible use of Council funds.

3.1.5   The disadvantages of this option include:

·     Cost and time with ensuring an adequate technical understanding across more than just the flood hazard.  The cost and programme implications of this to the LDRP will be detailed in a later report.

4.   Multi-hazards approach

4.1       ‘Flat land’ Christchurch is subject to a range of natural hazards including; earthquake induced liquefaction and land damage, fluvial and pluvial flooding, coastal flooding and coastal erosion, and tsunami.  Man-made hazards such as contamination of land are also significant.  These hazards affect different locations across the city with varying frequencies and magnitudes.

4.2       Some parts of Christchurch are subject to multiple hazards, particularly the areas adjacent to the lower reaches of our rivers. Many of these areas have been significantly impacted by the effects of the 2010 - 2016 Canterbury Earthquakes ('the earthquakes') that significantly altered the profiles of other hazards.  Long term planning decisions and more immediate infrastructure repair/remediation decisions would be better made in the context of the overall risk posed by all of these hazards. 

4.3       Since the earthquakes there has been a significant increase in our knowledge and understanding of various natural hazards.  The individual hazards have been and are being addressed through a range of council projects, programmes and processes: the development of the replacement Christchurch District Plan, the Regional Natural Hazards Work Programme, stormwater management plans, the Port Hills mass movement and rockfall protection structure programmes, and the LDRP. 

4.4       A 'multi-hazard' assessment approach considers the range of hazards which may affect an area. A multi-hazard assessment approach will provide a full picture of the total risk including likely physical damage, disruption, economic loss, and where appropriate, injuries and deaths.  The current, 'single-hazard' approach considers options for management of individual hazards and ignores costs and benefits associated with management of other hazards.  This approach may 'tie council into' considerable future additional costs for management of additional hazards, and call into question the original decision, for example if a decision was made to defend against a single hazard then subsequent decisions on other hazards could be influenced by the cost of implementing the original hazard defences.  A potential consequence of focusing on only one hazard is that actions taken to mitigate the effects of that one hazard may increase vulnerability/exposure to other hazards.

4.5       Some hazards are independent of each other and others are dependent.  There is potential for the hazards to have a cascading effect over both the short and long term, for example:

·   Additional land damage (for example, lowering of the ground surface) resulting from future earthquakes could significantly increase future flood risk (fluvial, pluvial, coastal and groundwater)

·   Land damage and subsidence could significantly increase the vulnerability to liquefaction in low lying areas - particularly where there is high groundwater

·   Sea-level rise will increase flood risk and groundwater levels and is likely to contribute to an increase in the area susceptible to liquefaction

·   Climate change is likely to result in an increase in the frequency of extreme weather events - increasing the risk of flooding, coastal inundation and coastal erosion

4.6       The interactions between the hazards are well understood at a conceptual level (Figure 1) but are not well quantified for Christchurch.  Future earthquakes could significantly change hazard and risk profiles, both directly and indirectly.

4.7       Effective risk reduction from natural hazards is only possible in Christchurch if all relevant threats are considered.  The natural system needs to be considered as a whole in an all-hazards approach.  Parts of Christchurch are vulnerable to a level of risk that for some hazards is undesirable and potentially, unacceptable.  A multi-hazard assessment would contribute significantly to a better understanding of consequences.

4.8       The most meaningful multi-hazard approach is to take account of the various effects of each hazard, and the relative probability of occurrence.  The effects of each hazard are assessed for each location, and then combined taking account of the relative probability of each hazard occurring.  Following a multi-hazard assessment, a framework will be developed to aid decision making on local intervention options.

4.9       The framework would also consider the protection of ecosystems, the integrated management of land and water, and the social and cultural impacts of the intervention options.  Options will be considered within this framework to compare costs and benefits, taking into account any uncertainties in the available information, and inform decision making.

4.10    A decision on which natural hazards to include depends on the existence and suitability of the individual hazard spatial information.  At this time the available information on the following hazards is of sufficient detail to inform a multi-hazard assessment: coastal erosion, coastal inundation, fluvial and pluvial flooding, tsunami, earthquakes (land damage and liquefaction), groundwater and contaminated land.  Further investigations into the interactions between the hazards will be required to inform hazard management options.  An investigations programme will need to be developed.

Figure 1 Impact of the Canterbury Earthquakes on Christchurch

4.11    Consideration will also need to be given to how the project interacts with external stakeholders and the public.  The strong desire, as expressed through the Tidal Barrier Pre-feasibility Study (Council Report 29 October 2015), of local stakeholder groups is to be involved in floodplain management, risk reduction options, and infrastructure decisions.  An appropriate methodology to engage with the public on the potential range of hazard intervention options will need to be developed.

4.12    The approach has been discussed with the LDRP Working Group that meets monthly for information briefings.  This working group includes Councillor representatives from the Infrastructure, Transport and Environment Committee with an invited attendee from Environment Canterbury.

Goals and objectives

4.13    The goal of a multi-hazard approach is to:

Develop and apply a robust framework to inform future infrastructure and long term planning decisions to reduce risk, and benefit current and future generations.

4.14    The objectives, that will need to be met in order to achieve this goal, are to:

·   Develop a sound base of scientific information to support hazard identification and evaluation, including quantification of interactions between hazards

·   Engage with relevant authorities to understand drivers for implementation of hazard mitigation and long term strategies

·   Test a range of hazard scenarios to establish the sensitivity of outcomes resulting from decisions to a range of possible future events

·   Develop a decision making framework based upon scenario findings to apply to LDRP and other projects

·   Develop suitable materials and information to present to the public to allow meaningful engagement

4.15    The results of the multi-hazard assessment will be useful for a range of Council roles, functions and responsibilities, including: planning and development, risk reduction decision making, consenting, and Civil Defence Emergency Management (CDEM) readiness and response.  The approach will promote risk reduction in an efficient and cost effective way through collaborative work programmes.

Regulatory, policy and strategic framework

4.16    The effective management of natural hazards, and associated risks, relies on the interaction of many statutes – Council has significant responsibilities for managing natural hazards under the Civil Defence Emergency Management Act 2002, Resource Management Act 1991, Building Act 2004, and Local Government and Official Information and Meetings Act 1987.  A multi-hazard approach would consider the cumulative adverse effects that are stated in Policy 4 of the NZ Coastal Policy Statement (2010):

Provide for the integrated management of natural and physical resources in the coastal environment, and activities that affect the coastal environment [with] particular consideration of situations where… significant adverse cumulative effects are occurring, or can be anticipated.

4.17    The replacement Christchurch District Plan addresses the risks from a range of hazards that Christchurch is exposed to using a 'single-hazard' approach (i.e. each hazard was essentially considered in isolation).  As a result the cumulative effect of multiple hazards is not well reflected for various parts of Christchurch within the plan.

4.18    The multi-hazard assessment approach fits with ISO 31000: 2009 Risk management - Principles and Guidelines, a well-established and well-accepted approach to assessing and managing risk.

4.19    The Greater Christchurch Resilience Plan is being submitted to the Urban Development Strategy Implementation Committee on 8 July 2016 for endorsement, prior to being submitted to Christchurch City Council for ratification on the 28 July 2016. The plan has identified the important building blocks for a Resilient Greater Christchurch and what we need to focus on to improve our resilience.  It recognises the interconnected complex nature of our problems and solutions in a holistic manner.  Government agencies and Councils will play a key role in a Resilient Greater Christchurch with an emphasis on consistency and collaboration that builds a trusting and participatory approach.  One of the key goals is understanding risk and becoming better prepared for future challenges acknowledging the fact that communities need to be supported to make complex decisions about how we invest for the future using clear, plain English information, with consistent language. Strong leadership at a strategic and community level will be needed to help us weigh up what our responses will be which will generically fall into three areas:

·        Risk Reduction – what can we do to avoid or mitigate risks to limit our exposure and impact of events 

·        Risk Transfer – insurance (including personal, corporate or state contingencies) is a means for us to safeguard our interests by allowing us to recover what we had.  It cannot replace lost life and the cost will reflect levels of risk

·        Risk Acceptance – We can never defend against all risks. The ultimate decision that communities and individuals therefore have to make is whether, taking other personal steps and measures, they are comfortable with the risks faced

4.20    Bringing these together, we will need to make informed decisions about our vulnerabilities, how much we are prepared to pay as communities and households to safeguard and offset those risks, and beyond this whether we can live with the residual risks, whether insured or not. 

4.21    Environment Canterbury and Canterbury territorial local authorities have developed a regional natural hazards work programme.  The first stage of the programme involves a focus on key issues and opportunities relating to roles and responsibilities, collaboration and co-ordination, regional research and communication and engagement.  The first stage will form the basis for ongoing work programmes for hazard and risk reduction initiatives. 

Current level of understanding

4.22    There have been significant and extensive investigations into some hazards since the earthquakes.  However, the current level of understanding across all hazards is not uniform and there is little quantification of the interactions between the hazards, that is, the total risk profile.  A gap analysis will be required to establish where further investigations are required.

4.23    Flooding related hazards have long been a focus of Council, given the low lying nature of Christchurch.  Post-earthquake investigations into fluvial and pluvial flood hazard have been undertaken in many catchments across Christchurch through the work of the LDRP and SCIRT, such as the Dudley Creek Long-term Flood Remediation project.  Tidal inundation has been explored within investigations initiated to inform the replacement District Plan and other investigations into topics, such as, estuary wave height and Akaroa inundation.  Many projects have considered sea level rise in accordance with Council Climate Change Policy 1995.

4.24    Other hazards have also been evaluated.  A 2014 NIWA study considered low probability tsunami events (1 in 2,500 year event) generated by a South American earthquake and potential impacts on the low lying areas.  The Earthquake Commission (EQC) have considered changes in groundwater level, liquefaction potential, subsidence and lateral spread as a result of the earthquakes.  The Ministry of Business, Innovation and Employment (MBIE) has provided considerable technical advice on how best to rebuild in liquefaction susceptible areas. Potential sites of contaminated land have been documented by Environment Canterbury.

4.25    A gap analysis may identify a number of issues that require further work, for example:

·   Statistical study into the coincidence of fluvial and tidal events

·   Estimating potential impacts of climate change and future earthquakes on Waimakariri River sediment loading and resulting potential changes in coastal processes

·   Local climate change estimates and effects on flooding drivers, such as sea level rise and storm surge, up to and beyond 100 year time horizons

·   Groundwater changes with sea level rise and potential impacts on the natural and built environment

Land Drainage Recovery Programme

4.26    The LDRP currently has scope to investigate options for flood hazard but not the other hazards within Christchurch.  The LDRP considers a range of flood management scenarios (i.e. different combinations of defence, policy intervention and adaptation).  Particular attention within the programme is being given to the downstream reaches of the Ōtākaro / Avon, Ōpāwaho / Heathcote and Pūharakekenui / Styx Rivers and areas adjacent to Ihutai (the Avon-Heathcote Estuary).  The programme will consider options to address flood risk from stormwater networks, waterways and the sea for a range of climate change, development and topographic scenarios (i.e. potential future land damage).

4.27    A question that will arise within the LDRP is: How do we make a decision on flood management in a multi-hazard environment?  A multi-hazard assessment will inform engagement and decision making on LDRP projects.  The LDRP has identified significant potential costs associated with remediation of flood risk and construction of flood defences in the lower river reaches.  A multi-hazard assessment of flood defence, and other floodplain management options will help to inform decision making on the most appropriate way to manage flood risk, now and in the future.

4.28    In applying a multi-hazard framework to aid decision making within the LDRP it is possible that the outcomes will vary from a single-hazard approach.  Future risks and costs associated with other hazards (and their cascading effects) may promote more resilient infrastructure being constructed or favour highly adaptive solutions (engineered or otherwise).

Local and international examples

4.29    There are many examples of attempts at combining natural hazards that have involved relatively simple addition of an attribute that is common to each hazard.  Local and international experience will be used in developing a multi-hazard assessment methodology.  The Council has already undertaken a similar exercise in assessing the multiple hazards of cliff collapse, rockfall and mass movement in a number of projects including the Sumner-Lyttelton Corridor and mass movement project. 

Risks and Mitigations

4.30    There is a risk to the LDRP of delays, should significant investigations be required to develop a strong scientific base of information on other hazards to inform decision making.   However applying a 'single-hazard' approach within the LDRP could lead to poor decisions or perverse outcomes.  Costs of inappropriate infrastructure investment may be financial (e.g. inappropriate engineering design, third party legal costs and cost of failure from another hazard) as well as reputational / political, environmental and social.

4.31    There is also a risk that the Council does not meet its legislative requirements under the CDEM Act 2002 and other legislation.  There are a number of possible alternatives to address these risks.

4.32    Applying a multi-hazard framework will lead to better informed engagement and decision making, however the messages will be more challenging to convey to the public.  Engagement with the community will be undertaken on the options developed for each project as they arise within the LDRP.

Next Steps

4.33    The first step will be to undertake a gap analysis and then develop an investigations programme to fill any gaps.  It is anticipated that an options report will be presented to the ITE committee for approval to progress the investigations programme.

4.34    The costs for implementation of an investigations programme has not yet been established.  Development of the investigations programme is considered within core council activities and costs are covered within existing budgets.  Any additional funding required to deliver the programme will be discussed in the next report.

1.   Purpose of Report

1.1       This report is to provide the Infrastructure, Transport and Environment Committee with a half yearly update on earthquake waste and environmental management. This includes statistical information and key environmental waste issues and locations being managed by the team.

 

2.   Staff Recommendations

That the Infrastructure, Transport and Environment Committee:

1.         Receive the information in the Waste and Environmental Management Team (WEMT) Half Yearly Report: July 2015 - December 2015.

 

 

3.   Key Points

3.1       Southern Response continued to undertake contaminated site remediation on higher risk sites using their global consents and noted a trend in uncovering historical asbestos contamination buried under replacement slabs.

3.2       The WEMT Teams experience with and knowledge of contaminated waste management has also supported non-earthquake related incidents, such as house fires involving asbestos, where the team work closely with NZ Fire Service to minimise risks and ensure effective contaminant remediation.

3.3       WEMT are now trained in the use of a hand-held X-Ray Fluorescence (XRF) Analyser. This allows for instant non-destructive alloy identification and elemental analysis, assisting in rapidly identifying a simple baseline of on-site contaminants.
