Situated in the Rhine delta, Rotterdam is often called the “delta metropolis”—a name that reflects both its location and the challenges it faces.

In a city that lies mostly below sea level, managing water from all directions – sea, river, groundwater, and rain – is a constant concern. So, how does Rotterdam handle the increasing precipitation?

One solution is “meervoudig ruimtegebruik,” or the multi-purpose use of public spaces. The idea is to combine essential water retention areas with valuable urban assets.

A prime example is the Zomerhofkwartier, a formerly neglected office district now serving as a test site for rainwater retention projects, focusing on de-sealing public areas.

Additionally, Rotterdam is revitalizing its unused harbor basins, integrating homes, hotels, and offices into these large waterfront spaces.
