Dike reinforcement Den Oever-Den Helder
The dikes between Den Oever and Den Helder protect 1.2 million North Hollanders from high water from the Wadden Sea. It concerns the Wieringer Zeewering, the Amsteldiepdijk and the Balgzanddijk. These dikes must be reinforced because they do not meet the latest safety requirements in all places.
For now, it's not unsafe. But to ensure that everyone can continue to live, work and recreate safely here and in the hinterland in the future, we are looking at which solutions are best suited. We like to do this in consultation with the environment.

Latest project status
The original plan was to submit the draft Water Act project plan and the draft environmental impact report (EIR) to our board before the 2023 summer vacation. After approval by the Provincial Executive of the province of North Holland, the public inspection would begin in mid-October. However, new insights regarding the strength of the dike require more time for in-depth research, resulting in a schedule delay. The investigations will reveal the impact on the project and what this means for the planning. More can be expected about this this fall. After sharpening the technical designs, the administrative decision-making procedure will follow as final preparation for the realization phase. The realization phase is expected to start in late 2025/early 2026.

Collaboration
The dike reinforcement is a project within the framework of the national High Water Protection Program (HWBP).
