How was the scheme carried out?
A new sea wall was built inland of the existing coastline.

700,000 tonnes of mud was pumped onto the area to
make up the new salt marsh.
In the June of 2006 the final landscaping took place and
the old sea walls were breached, this allowed the sea to
flood the newly created landscape.…read more

the man made salt marsh is once again a natural
haven for wetland birds.…read more
