Evaluation by E Wragg of PCA prior to development revealed a sequence of mid 17th and 18th century layers and pits, associated with domestic and possibly small-scale industrial activities. Sealed by these deposits was an apparent 13th century horizon of mixed redeposited natural sand and silt. No features were observed in this layer, although only a small area could be examined in the confines of the evaluation trench. Subsequent excavations by H Clough of PCA revealed a large, hitherto unsuspected Medieval water feature, which greatly exceeded the extent of the excavation area.
