This Rapid Appraisal (RA) was undertaken by Border Archaeology (BA) in response to an instruction from South East Water (SEW) regarding the proposed 13-0783 Best Beech - Coggins Mill Scheme, extending to the NE of the hamlet of Coggins Mill, Mayfield, East Sussex. It is Border Archaeology's considered opinion that a programme of Archaeological Observation (commonly known as a watching brief) would be the most appropriate form of mitigation in this instance, which should be focused on southern section of the pipeline route, where the scheme passes through the settlement of Coggins Mill adjacent to the Coggins Mill Stream (from NGR TQ 59959 27742 to TQ 60058 27892).
