Archaeological monitoring was undertaken to record any archaeological deposits which would have been disturbed by the groundworks. A CAT archaeologist monitored the excavation of a 3.9m by 1.8m rectangular trench for an underground LPG tank. Archaeological monitoring was carried out at Mount Stores, The Street, Pleshey, Essex during excavations for the installation of an underground LPG tank. Despite being located in an archaeologically-sensitive area, no significant archaeological deposits or material were observed during this work.
