Caldicot and Wentloog Levels
[2] The levels are formed from tidal deposits and alluvium, which have been recurrently inundated and reclaimed from the Severn Estuary by humans since Roman times.The Levels have been reclaimed from the sea at different times during the historic period, preserving evidence of patterns of settlement, enclosure and drainage systems.In 1531, Henry VIII set up Courts of Sewers to improve drainage, but without any powers to oblige landowners to carry out work.In 1828 the Commissioners for Sewers ordered a series of maps of the Caldicot and Wentloog Levels from Thomas Morris, a surveyor based in Newport.[9] In 2012, the IDB was criticised in a report by the Wales Audit Office for overpaying staff, paying for trips abroad for its members, and acting unlawfully on other occasions.
