Langstone Coastal Defence Scheme

What is the Langstone FCERM Scheme?

A Flood and Coastal Erosion Risk Management (FCERM) Scheme is being developed at Langstone, Hampshire.

Over the next 100 years, over 120 homes in Langstone are at risk of tidal flooding in an extreme event. The aim of this scheme is to develop and implement coastal management options to reduce the flood and erosion risk to the community, important heritage assets and Langstone Road (A3023) the only road crossing to Hayling Island. See background to the scheme, and progress made to date.

The options appraisal phase has now led to the development of leading options for defences. The next stage will be to develop the detailed design for these leading options.

Detailed design work will be undertaken for the leading options of the Core and Additional Scheme. For further information on what these areas include please visit the ‘Core and Additional Scheme’ page.

What is Detailed Design?

The options appraisal culminated in an outline design proposal for the most achievable solution, also known as the ‘leading options’. The detailed design phase progresses these leading options to a higher level of design detail, where we aim to refine:

• The technical details for planning, construction, and buildability
• Knowledge of the integrity of existing walls to form part of the scheme, where possible
• The impacts on heritage, landscape and environment
• The appearance, construction materials and finishes
• The whole life cost

For further detail about the scope of detailed design we have created a dedicated page, which can be found here.

Cabinet Meeting 28^th October

The Cabinet were provided with an update on the progress of the Langstone FCERM Scheme on the 28^th October 2020. The purpose of this meeting was to receive Cabinet approval on the outline design and proposed route alignment options, and further approval to commence with procurement of a professional consultant to undertake the detailed designs.
