Consultation opens on 100-year sea defence plans

A public consultation has launched into government plans to protect a Jersey bay against flooding and climate change for the next 100 years.

The government's Havre des Pas Coastal Flood Alleviation Scheme aims to protect the area by extending the coastline and integrating sea defences.

It said about 350 properties in the area are at risk from a one in 200-year flood event, which could rise to 1000 properties by the year 2120, without changes.

The public consultation on the £100m project which includes promenades and safe cycle routes is open until 12 September 2025.

The government's Shoreline Management Plan said global warming was causing sea levels to rise by about 3mm per year, increasing to 9mm per year by 2070.

It said: "This means we could see our sea levels rise by 0.82m by 2120.

"At this level, many of our sea defences would struggle to provide protection against flooding."

The Harve Des Pas scheme aims to improve the resilience of the area for the next 100 years, according to the government.

It said: "Covering the coastline from La Collette to La Grande Charrière Slipway, the scheme will address the growing risk of wave overtopping and rising water levels.

"While the existing defences remain in good condition, the area has been identified as the island's highest priority for upgrades.

"This is the largest coastal defences project undertaken in Jersey since the 1800's."

The government added extending the existing shoreline as part of the defences would allow greater opportunities for "public realm enhancements".

This includes new promenades, safe cycle routes, landscaped coastal gardens, and enhanced wildlife habitats for Havre des Pas.

Drop-in sessions on the plans are due to be held at the Lido from Tuesday 22 to Thursday 24 July, offering Islanders the opportunity to speak with the project team and learn more about the plans.
