Retreating Beach, Stabilising the Lagoon

Chesil Beach, Dorset, is continuously moving landward, reducing the size of The Fleet Lagoon and will eventually isolate the lagoon from the sea, cutting off the supply of brackish water to the lagoon and endangering important habitats.

UNESCO believes that processes of natural erosion should be preserved as a characteristic of the Outstanding Universal Value of the Jurassic Coast. Preventing Chesil Beach’s movement therefore would be detrimental to its World Natural Heritage Site status.

The ambition of this project is four-fold. Firstly, a network of tidal ponds maintain connectivity between the lagoon and sea ensuring the movement of Chesil Beach does not cut the saltwater supply to the lagoon, maintaining the salinity gradient of water within the lagoon, protecting the unique lagoon habitats. Secondly, connecting existing habitats to stabilise them, mitigating the eutrophication of the lagoon and increase biodiversity. Thirdly, a network of boardwalks and viewing platforms create a new recreational area, offering a new social value of the site. Finally, recording the change of Chesil Beach to capture important moments of a continuously changing landscape.

UNESCO believes that allowing natural erosion to continue is the most effective way to maintain the Outstanding Universal Value of the Jurassic Coast. However, this may cause isolation of The Fleet, threatening its habitats and biodiversity.

New bricks are formed using old London Bricks found along the Thames foreshore, retaining the memory of the site. This sustainable construction approach of utilising materials from the original site was also applied to the main design project.

Due to the long time span of the project the construction process was divided into three phases, preventing disturbance to sensitive ecosystems. The proposal is constructed using exclusively local building materials.

At low tide individual ponds will have different salinities and depths, providing a range of habitat conditions. At high tide ponds become connected maintaining the lagoons saltwater supply. Flooded walkways become markers of the changing landscape.
