Completed in 2013 at a cost of £28m, the project is the largest open-coast scheme in
Europe. It provides 1000 times better flood protection than the previous defence
system and has delivered extensive new intertidal and freshwater habitat.
The site contains 300ha of habitat of principle importance under the UK Biodiversity
Action Plan, including mudflats, reed beds, saline lagoons and grassland. This includes
183ha of newly created intertidal habitat important to wildlife on an international
level. Birds and other new wildlife began to appear at the site long before completion.
