Implementation of Lauwersmeerdijk-Vierhuizergat reinforcement project commences
Wednesday, April 5, marked the start of the Lauwersmeerdijk-Vierhuizergat dyke reinforcement project, which was celebrated in the port of Lauwersoog. On the sea dyke , residents, administrators, and entrepreneurs sea dyke a special poem about the dyke reinforcement. This was followed by the sounding of the ship's horn by grades 7/8 of the Mandegoud primary school in Kloosterburen. This signaled the start of tomorrow's dike reinforcement. After the festive start, young and old alike enjoyed an open house with information and activities.
Water safety
The reinforcement of the dyke additional tasks for nature, recreation, economy, and traffic safety will be completed in 2026. 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 conditions caused by climate change dyke next 50 years.
Most sustainable dyke
In carrying out this dyke reinforcement, explicit attention is being paid to the reuse of materials and the reduction of emissions. For example, emission-free electrical equipment is being used, as well as renewable and fossil-free HVO diesel. This will enable the water authority to reduce water authority by up to 95%. The sea dyke Westpolder and along the Vierhuizergat will be raised and reinforced with clay and stone cladding. Material from the current dyke reused and new material will come from the region. In the harbor, the dyke will be dyke and raised with sheet piling. The Waddenkwartier consortium, formed by GMB and Heijmans, is carrying out the dyke reinforcement work.
Dyke tasks for nature, traffic, and recreation
The dyke reinforcement project will also enhance the Wadden Sea ecosystem, dyke recreational activities around the dyke , and improve traffic safety. The latter involves the construction of a second access road to the port of Lauwersoog. A walking promenade along the harbor, a bike path, and a Wadden Sea viewing platform on the rural dyke the Vierhuizergat will also be added. Regarding nature, a salt marsh will be created as a natural transition from the dyke the Wadden Sea. A dyke passage an inland tidal area in the Marnewaard, covering approximately 70 hectares, will also be created. Furthermore, a pilot project involving reef elements is underway off the coast. In this way, the measures linked to this dike reinforcement ensure a more natural transition between land, mudflats, and water. We are implementing these additional initiatives in collaboration with council , the Province of Groningen, Rijkswaterstaat (on behalf of the Programmatische Aanpak Grote Wateren), and Groninger Landschap, also on behalf of nature organizations Natuurmonumenten (Dutch Society for Nature Conservation), Staatsbosbeheer (Dutch Forestry Commission) Natuur en Milieufederatie Groningen. Eisse Luitjens, councillor with special responsibilities atNoorderzijlvest Water Authority: “The broad and enjoyable collaboration surrounding this dyke reinforcement makes me particularly proud. Together with government agencies, nature organizations, and residents, we have added benefits for nature, traffic, and recreation to a strong dyke. Together with the private sector, we are reinforcing the dyke significantly lower emissions and the smart (re)use of raw materials. In this way, we are building the most sustainable dyke the Netherlands together. I warmly invite everyone to follow and visit this project over the next four years!”
Financing
A total of €158 million has been set aside for this project. On 15 February 2023, the Board of Directors of the Noorderzijlvest Water Authority made €136 million available for the dyke reinforcement. The Flood Protection Programme contributes 90% of the costs for the water safety project. Het Hogeland council finances the second access road to the port. Funding for nature development is available from the Wadden Fund, the Programmatic Approach to Large Water Bodies (PAGW), and the Groningen provincial executive.
Why reinforce the dike?
The nine-kilometer-long Lauwersmeer Dike, stretching from the R.J. Clevering Locks to the Westpolder, has protected the Lauwersmeer region and parts of the Groningen and Friesland hinterland from flooding for more than 50 years. Seawalls are assessed for water safety every twelve years. The height of the dyke the revetment on the water side no longer meet the relevant standards. Once the dyke reinforcement is complete, this section of the dyke will again meet safety requirements dyke next fifty years, providing protection against rising sea levels and extreme weather resulting from climate change. By 2050, all Dutch flood defences must flood defences the new safety standards. That is why, over the next thirty years, approximately 1,100 kilometers dyke will be dyke and 500 locks and pumping stations . We are doing this as part of the national Flood Protection Programme HWBP), which is part of the national Delta Program.
Nature development Grote Wateren
With these nature measures, the dike reinforcement contributes to achieving the legal objectives for Natura 2000 and the Water Framework Directive. The Ministries of Infrastructure and Water Management and Agriculture, Nature, and Food Quality have launched a separate investment program for this purpose, the Programmatic Approach to Large Water Bodies (PAGW). Rijkswaterstaat (RWS), the Netherlands Enterprise Agency RVO), and Staatsbosbeheer (Dutch Forestry Commission) on behalf of the PAGW with the aforementioned project parties and, simultaneously with the dike reinforcement, on measures to make the Wadden Sea nature more climate-proof and robust. The main goal is to restore the ecosystem of the Wadden Sea.
