<strong>Rotterdam</strong> is protected<br />
An adaptive strategy for our dykes and waterproof building<br />
in the near-river areas (floating city concept, buildings on<br />
poles etc.)<br />
Super levees combined with city parks (flexible solutions)
<strong>Water</strong> for an attractive city!<br />
Enforce existing qualities:<br />
• Extra water where it is possible, innovative<br />
solutions where needed<br />
• Extra surface water in reconstruction areas<br />
• Development of new housing concepts in old<br />
port areas
Innovations<br />
Extra waterstorage for 2050<br />
240.000 m3<br />
in city centre and “old<br />
city neigbourhoods”
Innovations<br />
Innovative where needed?<br />
<strong>Water</strong>squares
Innovations<br />
- Storage of water<br />
- Reducing the heat island effect<br />
- Improving quality of the air<br />
- Adding more green space<br />
- Saving energy<br />
- More biological diversity<br />
Green roofs
Innovations
Implementation with our waterpartners<br />
Fast if needed, slower when possible...<br />
What are the priorities?<br />
1 urgent: now or never<br />
2 use opportunities (other developments)<br />
3 focus on attractive examples<br />
4 multipurpose
Cooperation is essential<br />
1. Different organisations, different responsabilities and<br />
tasks<br />
2. Complex challenges and high costs need a broad pact<br />
of waterpartners<br />
3. Expensive and innovative solutions ask for a broad<br />
basis and (inter)national exposure
Conclusions<br />
• We can use the threat of water for strenghtening the<br />
main ambitions of the <strong>Rotterdam</strong>:<br />
<strong>Water</strong> brings opportunities for a more attractive city<br />
• Regular solutions are not enough anymore: we do<br />
need innovations<br />
• We need to do it together
