Gunsite flood alleviation project

About the project

In recent times, the areas around the Gunsite and the bottom of Beaumont Hill have been affected by flooding. This is caused by sea water coming over the wall during storms and high spring tides.

To reduce the risk of flooding the sea wall has been raised by 30cm. 

This is carried out in three phases:

  • Phase 1: raising the sea wall from the Gunsite slipway to Le Perquage car park
  • Phase 2: from Le Perquage car park going east towards St Helier
  • Phase 3: construction of flood gates

Phase 1: Completed in 2017

Area of work: From near the Perquage car park, going west, to the Gunsite slipway.

Phase 2: Completed June 2018

Area of work: From the Perquage car park, going east towards St Helier (120 metres of sea wall).

Phase 3: September 2018

Permanent flood gates will be installed . The gates will reduce the risk of flooding in Beaumont during extreme weather.

The flood gates will remain open until needed and can be closed in minutes.

Area of work: At the end of the Gunsite access road.

Using the promenade

Pedestrians, cyclists, le Petit Train, Funbikes etc can still use the promenade.
