Climate change - overview

The global climate is changing – land surface temperatures have risen by around 0.7C since 1970sSome degree of further change is unavoidable and warming will continue over the next century at leastUKCP09: • increases in summer and winter temperatures • increases in winter rainfall, decreases in summer rainfall• more days of heavy rainfall• rising sea levels.

2003 heat wave: normal by 2040s, cool by 2080s?

The need to adapt to climate change

UK is already vulnerable to extreme weatherLAs already manage these risksPreparing for climate change is crucial because:1.We should improve resilience to the current weather2.Climate change will increase current risksAdapting to climate change is about resilient services

National adaptation policy

Climate Change Act 2008Climate Change Risk Assessment

National Adaptation Programme

Adaptation Reporting Power

Adaptation Sub-Committee

Climate Ready

New role for Environment Agency in 2012Climate Ready is a service that aims to help key sectors increase their resilience to climate risksProvides general information to help organisations adaptOffers a tailored support service and runs specific projects with partners (e.g. these workshops...)

UK Climate Change Risk Assessment

National overview of climate change risksDetailed analysis of 100 risks in 11 sectorsRisks evaluated by size and timing of impacts, and confidence in the assessmentFlooding identified as biggest risk in most sectors, including transportCCRA should inform adaptation response

National Adaptation Programme

National Adaptation Programme issued 1st JulyGovernment’s response to the CCRA - describes actions Government and others are taking to adapt to climate changeNAP highlights economic consequences of local transport failureSeveral actions to improve local transport resilience

Department for Transport

DfT considers that “adapting transport .... is an important part of developing and maintaining a network that supports long term economic growth“Local transport authorities have duty to improve resilience of local transport to climate changeAdaptation guidance included in several pieces of DfT guidanceIn NAP DfT pledges to continue building climate resilience into its transport and roads strategies – e.g. Roads Strategy 2013

Adaptation at the Highways Agency

Adaptation given high priority at HA HA made detailed plans for long-term resilienceCarried out assessment of climate risksMade changes in response such as:

increasing capacity of drainage standardintroduced new pavement specifications

HA believes its changes and plans will save money and protect its assets

Climate Change & Local Infrastructure

Perspective from the Profession: Local Authority

10:10-10:20

Climate Change & Highways – The Impacts

• The climate is changing in the UK • Despite mitigation efforts we are committed

to a level of climate change • Warmer summers, increased rainfall

(intensity of rainfall & flooding), increase in storm surges and high winds

Vulnerabilities of local highwaysIncreasing temperatureMelting surfaces & deformation of asphalt

More intense rainfall & flooding Bridge scour & possible collapse

Vulnerabilities of local highwaysRising sea levels, coastal erosion & floodingPermanent loss of infrastructureHigh winds, storms & storm surges Debris blown onto roads

The Big Challenges • Increasing frequency of

severe weather events

• Austerity & budgets

• Place services competing for smaller slice of the pie with People Services

What to consider……• Identifying the risks– example in guidance

document from Cheshire West & Chester• Wider service delivery & interdependency

• Reputation• Cost

Opportunities• Make the link between people and place

• Resilient local highways network = resilience for business, schools, social care

• Public Health - link to health and wellbeing agenda

ISSUES IN THE EAST OF ENGLAND? • Challenges of roads on peat soils• Cold winters• Drought damage • Under-investment and fragile asset• SUDs• Economic growth / Transport strategies• Joining up “place” services

Questions & Audience Discussion

1. Share local highway related weather/climate issues that you have experienced in your organisation

2. Identify key future threats you expect

3. Where do you currently get information and support on these issues from?

Climate projections in useCambridge University Boat House, Ely

Background to the project

• CUBC require a new home in Ely

• Complex site selection process

• Site constraints1. River Great Ouse

2. Middle Fen Bank flood defence

3. Flood zone 3

4. Dangerous existing site access

5. EA retain dredging and disposal rights

Key considerations

• Direct impact of flood waters

• Breaking through existing flood defence line

• Flood mitigation

• Surface water disposal

• Pollution/water contamination

• Vehicle site lines

• Erosion of adjacent peat soils

Entrance layout

Retaining sightlines

Protection level

Summary/lessons learnt

• Effects of climate change should be considered – even for seemingly small projects.

• Some impacts can be numerically modelled, others are require a more subjective approach.

• Consideration of exceedence/inundation events (to what degree?).

• Multi-stakeholder input required (Developers, Environment Agency., Highways Authority, Internal Drainage Boards etc.).

• Holistic approach to highway design, not just code compliance.

• Extended skill set – highways engineering, pavement engineering, drainage engineering, architectural, landscaping, maintenance etc.
