New Dune and Groon Area Renaissance: End of 4 years of work on Colleyville-Montgomery Beach.

“Without this work, the sea would undoubtedly have continued to rise on the coast and reach the promenade and cycle path that runs along the coast in this part of the Côte du Nacre. Explains Michel Vericot, Ouistreham district councilor. Four years of work to invest three and a half million euros in Caen-la-Mer, including 300,000 euros covered by the Calvados division. “But today the count has appeared, and nature is regaining its rights.” Emphasizes Romain Bell, Mayor of Ouistreham Riva Bella and Deputy Head of the Department responsible for Ports, Coasts and Tourism.

Ears rehabilitation

Fifty-eight wooden pieces were restored, or even six of them, which were badly damaged, were changed. These grooves placed in the sand perpendicular to the sea have the role of retaining sand during strong swells during storms. Strong winds in recent years have pushed sand from Lyon-sur-Mer Beach towards Ouistreham, and even further towards Merville and Cabourg. Hence these ears play a major role.

Dam restoration

Dams have also been reinforced or rejoined, including those in Lyon-sur-Mer that suffered badly from the storms. Large blocks of stone weighing several tons from the base of the dam, which had been dislodged by strong winds, had to be put back in place.

Enhancing the Colville-Montgomery Natural Sand Dune Area

Oyote plants, perennials familiar in sandy soil thanks in particular to their deep roots, have been replanted. This was not without difficulty due to the storms that swept them away. But thanks to the installation of the ganeville, these beautiful wooden fences, and the witches, a kind of embankment made of intertwined branches, the Oyats family ended up coming back to life and the sand came back, recreating natural sand dunes four to five meters high. . Enough to prevent the coast from being concreted.
