17 trenches, 5% sample of Areas 1-3, along an 8.4km long pipeline. The three areas of trenching were identified following consultation between Suffolk County Council Archaeological Service and AECOM. Area 1 was selected for trench evaluation on the basis of records of multi-period find scatters and the site of the post-medieval mill; Area 2 targeted findspots of medieval and Romano-British artefacts; Area 3 correlates with a Romano-British artefact scatter. The uncovered features comprised seven ditches, six gullies, two postholes/pits and a peat deposit, and were found in nine of the trial trenches. The distribution of the 'positive' trenches indicates archaeological remains are present across the pipeline route, albeit with no particular concentration. Two of the ditches (both in Area 1) are post-medieval (late 17th-18th century AD). The remainder of the features are undated; it is therefore uncertain how they relate to the existing records of findspots in their vicinity. A medieval silver penny (Richard II; 1377 to 1399 AD) recovered from metal detecting in Area 2 complements other similar finds from the vicinity, however. Assessment of the soil samples indicates that there is some potential for the recovery of environmental evidence from some of the features. Overall, the evaluation has met its aims and objectives, within the constraints of the generally limited evidence hindering a better understanding of the excavated features.
