Tools for Resilient Urban Design

4. Overview
• Adaptation assignment & spatial planning
• A planner’s perspective
• Tools to
• Quantify the assignment
• Support planning and design
• Recent developments

5. Hazards and challenges

6. Climate is changing

7. Flooding (coastal, fluvial, pluvial, groundwater)

8. Drought

9. Heat stress

10. Other relevant developments
200519701900
To be considered in our planning

11. How to plan for adaptation

12. The planning process
Initiative phase
research and analysis
programme development
Design phase
conceptual design
preliminary design
site plan
implementation plan
Stress Test
Vulnerability scan
Strategy
Selection of measures
….
…. design

13. The planning process
Tiered approach
Three steps:
1: Vulnerability scan
2: Strategy to reduce vulnerability
3: Select set of adaptation measures

Vital and vulnerable objects, networks
• Power
• Telecom
• Hospitals
• Evacuation routes
• Elderly homes
• Chemical plants
• … … …
vulnerable people, animals and
vital objects and networks
require extra protection

20. CIrcle tool to analyse chain effects in vital infra

21. Tools
• to identify the assignments
• to support planning & design

22. Many, many options:
Lots of measures can be taken

23. Soft solutionsHard solutions
flexible and cost-effectiveless flexible, extra investment
more space but multi-functionalless space required
Blue-green solutions preferred over grey ones

24. Discuss and co-design solutions
with experts and stakeholders

28. Dashboard
Ranked list of 62 blue, green and
grey adaptation measures

29. Dashboard
Dashboard with KPI’s
based on key figures, e.g.:
• Retention [m3]
• Peak flow reduction (Treturn [yr])
• Seasonal storage [m3]
• Cooling effect [oC]
• Groundwater recharge [mm/yr]
• Water quality improvement:
• Nutrients (%)
• HMs, PAHs, min. oil (%)
• Bacteriological quality
• Costs (implementation and maintenance)
• Benefits and ‘co-benefits’

30. Recent developments
First applications of these tools:
in the Netherlands
Utrecht, Dordrecht, …
abroad
London, Beira, Oaxaca, …

31. Discussion

32. Discussion
Before you leave, please tell us:
• Is this what you need?
• What would be the first thing to be improved?
• Applicability
• - in NL?
• - abroad?

33. Closing
Thank you for your attention!
