1. Adapting to Climate Change By John Thorp

3. Climate Change Predictions Hotter drier Summers Milder wetter winters More extreme rainfall events Increased wind speeds Rising Sea levels

4. What is the Impact Key Highway Service Areas –Winter Service –Trees and Vegetation –Materials and Resurfacing –Drainage and Structures

5. Winter Service Unpredictability Customer Expectations Highway Service Unavailable

6. What Measures Better Predictions Better Resilience Better Techniques Working itself out of a job

7. Trees and Vegetation Potential change in the growing season Faster growth of trees More damage claims from householders More trees falling in high wind

8. Adaptations More time on inventory of trees More time on maintenance of trees More risk management Ensure trees planted correctly Developing a Strategy for Urban Trees

9. Materials Softening and deformation under load Melting Roads Shrinkage and Cracking Potholes

10. Materials

11. Adaptations Mimic French standards Alter surfacing techniques Improve pothole repairs Waterproof Climate Change Act 2008

12. Drainage Flooding –Sea level rise –Insufficient water storage –Damage to highway –Landslip, erosion and Scour –Flood and water Management Act 2010

13. What measures Surface Water Management Plan Preliminary Flood Risk Assessment Local watercourse management Introduce SUDS Introduce permeable surfaces Change materials to cope with flooding Adapting Gulley emptying frequency Increase capacity at bridges and culverts Increase inspections to at risk structures from scour Introduce risk management to landslips
