Three Shells Lagoon report recommends long-term way forward

November 11, 2026

A report on the future of Three Shells Lagoon is recommending the removal of the existing lagoon structure and the restoration of the site to a natural beach environment.

The recommendation follows extensive technical assessment and consideration of a range of options. The report identifies restoring the site to a natural beach environment as the preferred long-term solution and the proposal will now be considered by Cabinet (16 November, item 9).

The recommendation supports the Joint Administration's commitment to resolve the long-standing issues surrounding the failed lagoon scheme and improve the surrounding environment.

Cllr Matt Dent, Cabinet Member for Business, Culture, Music and Tourism, said: "For years, Three Shells Lagoon has been a costly headache for the council and a source of frustration for residents.

“The current administration inherited a site that has consumed significant public money over many years. Management of the lagoon has become increasingly difficult with increased restrictions on what maintenance works can be done. Despite investment under previous administrations, the Lagoon remains fenced off and unusable, and there is no realistic option that avoids further substantial cost.

“We have reached the point where we need to cut our losses. The lagoon has become a monstrosity that is no longer fit for purpose, and restoring the site to a natural public beach environment is the most practical and sustainable long-term solution.

“This administration made a commitment to tackle the long-running issues surrounding the lagoon, and this recommendation represents an important step towards finally resolving them.”
