Black heavy clay silt was scoured from the channel bed by the dredger Lord Willingdon and deposited in vast quantities upon the site, whilst around the perimeter a strong four-foot stone wall was constructed as a safeguard against inroads from the sea. Trees were planted along the coast to keep the soil firm.
