The evaluation at Harvey's Depot, Pinwell Road, Lewes, revealed substantial deposits of made ground in the western part of the site. Historic maps indicate that the site was formerly within a floodplain area associated with the Winterbourne Stream, and it is therefore likely that the ground level was built up in the 19th century to prevent flooding. Once it was established that the new development was unlikely to significantly affect any buried archaeological deposits, which may yet be present beneath the made ground, it was decided that not all the proposed trenches needed to be excavated.
