Construction of Lauwersmeerdijk tidal culvert marks start of unique nature projects

Attendees at the launch of the nature projects

Annette van Velde, councillor with special responsibilities Noorderzijlvest councillor with special responsibilities : “In 2023, work began on reinforcing the dike. It's wonderful that we can now also start implementing the nature projects! Together with government agencies, nature organizations, and the Ministry of Defense, we have dyke these nature projects for a healthy Wadden Sea ecosystem and a strong dyke . Together with the market, we are reinforcing the dyke significantly lower emissions and smart (re)use of raw materials. In this way, we are building the most sustainable dyke the Netherlands. I cordially invite everyone to come and see for themselves during Construction Day on Saturday, June 8.

Linda-Rose Santhagens, director of Rijkswaterstaat North Netherlands: "This Lauwersmeerdijk-Vierhuizergat project shows that it can be done! It is a wonderful combination of dike reinforcement and nature development in the Marnewaard and along the edges of the Wadden Sea. The 70 hectares of intertidal area that is being created here is truly unique in its kind and size. I am therefore proud that it has come this far, thanks in part to the commitment and conviction of all the partners involved!" 

Susan Top, deputy for the province of Groningen: "In this special part of the Netherlands, the dyke reinforcement, which is necessary for water safety, offers an opportunity to link nature projects to it. We have worked hard with all those involved to make this possible. In this way, we are taking steps together in the development of a coast that is future-proof and also provides unique nature." 

What are the nature projects? 

Over the next three years, dike workers will also be working to make the transition between land, mudflats, and water more natural by constructing: 

• Marnewaard tidal area: we are constructing a dyke passage tidal area in the Marnewaard.
• Artificial reefs and tidal pools: we are constructing an artificial reef along the dyke dyke tidal pools at the foot of the dyke . This will make the transition between the mudflats and the dyke . 
• Natural salt marsh development: we are creating a natural salt marsh along the dyke the Westpolder. 

The implementation of the nature projects will take around three years and will be completed at the same time as the dike reinforcement. 

Dike reinforcement 

Reinforcement of the dyke necessary because it no longer meets water safety standards. Once the work is complete, the dyke will once again protect against higher sea levels and extreme weather caused by climate change dyke next 50 years. The dyke reinforcement is part of the national Flood Protection Program (HWBP) and thus the national Delta Program.
