6 Rotterdam Adaptation Strategy (RAS) Rotterdam is climate proof in 2025 This means: Climate change is incorporated in spatial planning tools in order to continuously take into account the effects of climate change while developing Rotterdam Measures have been taken to suffer the least from climate change in the next decades.

7 Rotterdam Adaptation Strategy (RAS) Rotterdam is climate proof in 2025 This means: Climate change is incorporated in spatial planning tools in order to continuously take into account the effects of climate change while developing Rotterdam Measures have been taken to suffer the least and profit the most from climate change in the next decades.

8 Synergy!!!! Water safety Water quantity Water quality Urban planning + spatial development strategy 2030 Water = opportunity for an attractive and economically strong city!

10 Waterstorage contributes to an attractive city

11 South Park

12 Green Roofs mitigation + adaptation + attractive city

13 5 tracks Water safety City Climate Urban water management Adaptive building Accessibility

14 Several instruments Roadmap (1 for each track) - ambition 2025 (backcasting) - key decisions (forecasting)

15 Delta Programme Rotterdam Region New stormsurge barriers + new river + new dykes Existing Dykes Existing Dam Existing Storm Barriers New Dykes New Storm Barriers

16 Several instruments Roadmap (1 for each track) - ambition 2025 (backcasting) - key decisions (forecasting) Climate toolbox - longlist shortlist adaptation measures - sustainability of measures - links between measures - contribution to overall project goals

17 Adaptation strategies matrix Improving resistance Improving resilience Minimizing chance Minimizing consequences Stimulating recovery Region City District Street Building

18 Water safety strategy Improving resistance Improving resilience Minimizing chance Minimizing consequences Stimulating recovery Region new Delta plan evacuation plan early warning system City improving dykes avoid vulnerable functions in vulnerable areas. allevate infrastructure use boots to transport people and goods District realize circle dykes communication double infrastructure emergency shelter allevate energy system back up energy system, water etc adapting public space Street integrate buildings in dykes safe havens sandbags pumps Building building on mounds wet proof ground floor dry proof ground floor wet proof decoration

32 Heijplaat

33 Heijplaat

34 RDM RDM New village Old village

35

36 Mean Height

37 Heijplaat is prepared for high water

38 Dike or fully elevate not preferable Full dike around the old village not preferable Fully elevate new village and facilties Minimizing chance

39 House with elevated front exit

40 Flood proof set up RDM buildings No solution for the old village Flood proof buildings Minimizing consequences

41 Flood proof set up RDM Elevating working floor Higher buildings within the existing building Elektrical equipment at a safe height Vulnerable equipment high Floor easy to clean Etc.

42 Mounds in the public space Evacuation routes at a safe height Vertical evacuation in high buildings Stimulating recovery

43 Flood proof set up RDM buildings Evacuation routes on safe height and a network of mounds in the public space Hoogwaterbestendige nieuwbouw en geschikt maken voor verticale evacuatie Small structural interventioons Communication program over water safety and developing evacuation plans Water safety strategy (proposal)

44 Conclusions Climate change as an opportunity for an attractive, livable city and economic chances Cooperation between specialists and urban planners is essential, adaptation should be incorporated in and linked to other processes Use a balance between minimizing possibility, minimizing consequences and stimulating recovery with custom made solutions per area
