Leading off from the south end of the bank are a few shortish stretches of ditch (on same alignment) possibly once forming the edges of ditched trackway/droveway? More and clearer examples of which can be seen to the east (see NHER 36871). (Mapped by A Miller, but not mentioned on his recording).

Inter-tidal survey (Environmental Zone 10), Context 904:
A structure was recorded amongst Wells saltmarshes. It was formed from five or six rows of timber posts, between three of which spreads of large flint nodules were present. In a number of places patches of horizontally laid wattling were identified. An 18th to 19th century brick fragment was collected. Either side of the structure, between TF 91874 44008 and TF 91917 44069, was a low linear rise in the saltmarsh (it was no more than 0.2m high). This suggested the presence of a bank, and that the posts, flint and wattling were its eroding internal structure. Maps from 1782 and 1784 show a sea defence bank in this location, one which is more than likely to be it ((S3-4), in (S5-6)).
See assessment report (S7) for further details.
The associated archive has been deposited with the Norwich Castle Museum (NWHCM : 2017.421).
