Sea dyke requires attention in certain areas; no immediate danger

Test results

Every 12 years, the safety of the sea dykes known asflood defences in water authority terminology) in our country is assessed based on the latest knowledge and standards. For more information about the “National Assessment of Flood Risk for Primary flood defencespublished today, visit the website of the Primary flood defences Assessment flood defences Dutch Water Authorities at . 

This assessment Noorderzijlvest Water Authority that a 90-meter section of sea defence of the pumping station Drie Delfzijlen pumping station , extending to the border of the Hunze en Aa’s region , does not meet safety standards. There is no immediate danger here. Extremely high water levels (NAP +4.80 m) that we have experienced in the past would have to be significantly exceeded before any real damage to the dyke .

The lower limit of the grass covering on the sea dyke Eemshaven is too low. The asphalt covering is reaching the end of its technical lifespan. In line with the water authority duty of care, we water authority its quality closely in the coming years.

As part of the national Flood Protection Programme , an assessment Flood Protection Programme this year to determine which flood defences need to be reinforced flood defences 2050. This assessment flood defences also flood defences the sections of our flood defences that have been deemed substandard. We will develop an action plan this year outlining how we flood defences these sections of the flood defences in the coming period until they are actually reinforced. 

Lauwersmeerdijk-Vierhuizergat is already being reinforced

The Lauwersmeer dike lies between Lauwersoog and the Westpolder. The Lauwersmeer dike-Vierhuizergat section will be reinforced starting this year. This sustainable dyke completed in 2026 and will then once again meet safety standards.
