An archaeological strip map and sample in advance of residential development was conducted on land at 200 - 204 South Coast Road, Peacehaven, East Sussex (NGR) from the 14th of May to the 1st of June 2010. Significant quantities of residual Mesolithic and Neolithic flintwork were recovered from the site. The late Iron Age to Early Roman period is represented by a slight curvilinear boundary or drainage ditch, perhaps an outlying field boundary associated with the newly discovered settlement identified at the Peacehaven Water Treatment Works to the north-east of the site. Several other undated features were identified, including two substantial postholes.
