Never take away a citizen’s parking space!

A Problem:
20-50% of city landscape is parking space

1. Total surface Rotterdam (without water): 206,44 km²
   
2. Parking surface in Rotterdam ~ 40 - 100 km. (ref.: flat roofs in Rotterdam ~ 18 km²)
3. (and btw 23 hrs of 24 hrs, cars are just sitting still on the parking lot)

A Solution:

Wild Water Parking

1. Temporary storage of rainwater 
   
2. Good enough to park your car on top
   
3. Modular foundation to start rebuilding the city for car-free spaces
