The second Maasvlakte is located west of the (first) Maasvlakte. It is a new piece of land covering approximately 2,000 hectares. Due to its location, surrounded by the North Sea, elements such as wind and sand have free rein. The southwest wind often blows strongly in that area. As a result, sand from undeveloped construction sites reaches the outer edge of the Maasvlakte. Together with the Port of Authority of Rotterdam, ProRail has already implemented various measures. Meanwhile, we are also looking for more permanent solutions that will lead to a better controllable situation. To achieve this, we are collaborating with the knowledge institute Deltares, which specialises in water and subsurface research. This research has been completed, and the recommendations have been implemented.
