Ground Investigation Begins for Havre des Pas Coastal Flood Defence Scheme

Investigation work to support plans for improved coastal flood protection at Havre des Pas is under way, as Jersey prepares for the effects of rising sea levels and coastal flooding.

The Government of Jersey said specialist drilling and ground testing would be carried out at several locations along the beach and shoreline to assess ground conditions and help inform the development of the proposed flood defence scheme.

The Havre des Pas Coastal Flood Alleviation Scheme is intended to provide long-term protection to the exposed coastline, which faces the risks of wave overtopping and rising sea levels.

The investigation was expected to continue until Wednesday, with work taking place at a number of sites along the beach.

Officials said the beach would remain open to the public during the investigation. However, small sections would be temporarily fenced off for safety reasons, and some slipways would be closed for short periods.

Government project documents identify the coastline stretching from La Collette to La Grande Charrière Slipway as the island's "highest priority" for coastal flood protection.

Projections indicate that rising water levels could threaten homes, businesses and public spaces along the coastline by the early 2040s, highlighting the need for long-term measures to reduce the risk of flooding.

The latest ground investigation is expected to help inform the planning and design of measures to protect the Havre des Pas coastline in the years ahead.
