Southsea Coastal Scheme Underway


Southsea Town’s sea defences, some of which date back to World War Two, need updating and have become a potential flood risk. To help tackle this and to protect the town’s future, Portsmouth City Council has officially begun Phase 1 of The Southsea Coastal Scheme - a multi-million pound project to create new coastal defences and one which passes close to Southsea Marina. Besides providing flood protection, the Council’s aims is to improve the setting of the many historic and cultural features that make town’s seafront so unique.

The coastal scheme is the UK’s largest local authority-led coastal defence project and is set to improve the seafront for future generations. Phase 1 of the project is now officially underway with works being carried out to lay the foundations for the new sloped sea wall, known as a ‘revetment’.

Following an £100m investment funding from the Environment Agency, the new sea wall will stretch from Old Portsmouth to Eastney, and will require the construction of a compound area, demolition of the existing defences, installation of a temporary shingle working platform, installation of sheet piling, placement of precast concrete units and placement of a rock revetment.

Mariners are requested to keep a good lookout and pass at slow speed whilst the dredging and construction works are being conducted. A listening watch will be maintained on VHF Ch 11 throughout the project and the Queen’s Harbour Master will provide updated Notice to Mariners, which will be available to view here
