All groundworks that had the potential to impact upon archaeological deposits were undertaken whilst under the observation of an archaeologist. Mechanical excavation was conducted by use of a tracked 360� excavator, which was equipped with a toothless grading bucket. Where possible archaeological features and deposits were identified, these were subject to appropriate investigation by the archaeologist. Due to the presence of deep sections and flooding the recording of deeper interventions was undertaken from outside the excavated area. The archaeological observations identified part of a probable Roman soil/demolition layer, which was present 0.78m (106.45m aOD) below the Modern ground surface. The layer contained 2nd century Roman pottery, Roman CBM including tegula, imbrex and box-flue tile, a piece of ceramic tessera, fragments of animal bone and oyster shell. A possible stone-built drain or soakaway remained undated.
