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.
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.
Synergy!!!! Water safety Water quantity Water quality Urban planning + spatial development strategy 2030 Water = opportunity for an attractive and economically strong city!
Waterstorage contributes to an attractive city
South Park
Green Roofs mitigation + adaptation + attractive city
5 tracks Water safety City Climate Urban water management Adaptive building Accessibility
Several instruments Roadmap (1 for each track) - ambition 2025 (backcasting) - key decisions (forecasting)
Delta Programme Rotterdam Region New stormsurge barriers + new river + new dykes Existing Dykes Existing Dam Existing Storm Barriers New Dykes New Storm Barriers
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

Heijplaat
Heijplaat
RDM RDM New village Old village
Mean Height
Heijplaat is prepared for high water
Dike or fully elevate not preferable Full dike around the old village not preferable Fully elevate new village and facilties Minimizing chance
House with elevated front exit
Flood proof set up RDM buildings No solution for the old village Flood proof buildings Minimizing consequences
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.
Mounds in the public space Evacuation routes at a safe height Vertical evacuation in high buildings Stimulating recovery
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)
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
