460-Metre Rock Wall Planned to Save Trou-aux-Biches from Coastal Erosion Threat

The Ministry of Environment has launched an ambitious coastal management project at Trou-aux-Biches, designed to tackle worsening shoreline erosion through the installation of significant rock defences.

At the forefront of the initiative is the construction of a 460-metre rock revetment at the southern end of the beach.

This coastal wall will utilise two distinct structural designs to provide a long-term buffer against the elements and protect the threatened coastal zone.

Strategic Infrastructure

To further stabilise the shoreline, the project includes the installation of five groynes at the northern end of the beach.

Four of these structures will be T-shaped, specifically engineered to intercept marine currents and encourage the natural accumulation of sand.

Public and Commercial Benefits

Beyond mere protection, the Ministry aims to enhance the public space and improve local infrastructure.

The ultimate objective is to maintain a continuous sandy beach, particularly in front of hotel establishments, ensuring easier movement for beachgoers and preserving the area’s aesthetic value.

Key Project Specifications

• Total Revetment Length: 460 metres
• Location: Southern extremity of Trou-aux-Biches
• Northern Features: 5 groynes (4 T-shaped)
