Rising sea levels and more rainfall will increase the risk of flooding in some areas of Jersey. Our existing sea defences and drains protect us from flooding during storms, high tides and heavy rainfall. Jersey’s shoreline management plan aims to make sure that our coastal defences continue to protect the island over the next 100 years. 

The area around the Gunsite and the bottom of Beaumont was flooded on several occasions when there were storms and high spring tides and those incidents were worsening due to climate change. It was agreed that something needed to be done to improve the situation so in 2017 the seawall in this area was heightened to help combat flooding. The wall has a curve on the sea side to deflect waves. This a common shape of sea wall found around the Island and is similar to sea wall construction throughout the world.
