A programme of archaeological monitoring and recording (AMR) was undertaken during the installation of a culvert and the ground reduction for the basin for a new wetland. During the investigations it was noted that the ground disturbance works were not impacting levels below the subsoil. As such, in consultation with Wiltshire Council Archaeology Service, it was determined that no further monitoring of groundworks was required. The watching archaeologist monitored all mechanical excavations associated with the works specified above. No archaeological features were observed during the investigation, though a possible palaeochannel was recorded. Spoil from machine stripping and hand-excavated archaeological deposits was visually scanned for the purposes of finds retrieval. Artefacts were collected and bagged by context. All artefacts from excavated contexts were retained, although those from features of modern date (19th century or later) were recorded on site and not retained. All exposed deposits and features were recorded using Wessex Archaeology's pro forma recording system. Due to unforeseen circumstances, it was not possible to survey the monitored locations using a Leica GNSS connected to Leica's SmartNet service. Instead, the location of the AMR and the works observed have been related to client plans of the development. A full photographic record of the works was made. No archaeological features were observed during the works, though some burnt flint and struck flint was recovered, suggestive of a background of early land use within the site and the surrounding area. Fluvial deposits with a distinctive iron-rich clay were recorded on an approximate south-east - north-west alignment and may pertain to a palaeochannel traversing the site.
