Evaluation was carried out as per the brief and the WSI. Thirteen trial-trenches were machine-excavated under the supervision of a CAT archaeologist. Trenches T2-T7, T9 and T11 were 30m long and 1.8m wide; trench T1 was 21m long and 1.8m wide; trench T8 was 40m long and 1.8m wide; trench T10 was 25m long and 1.8m wide; and trenches T12 and T13 were 7m long and 1.8m wide. Trenches T7 and T11 were excavated in two sections to avoid a sewage pipe and trench T10 was positioned slightly differently from the trench plan proposed in the WSI due to the presence of trees. Trenches T12 and T13, as well as an extension some 5m long on the western side of trench T8, were excavated to uncover more of ditch F4/F5/F6/F7, at the direction of the ECC archaeological monitor. An archaeological evaluation (13 trial-trenches) was carried out on land north of 48 Woodrolfe Road, Tollesbury, Essex in advance of the construction of a new residential development. The site lies to the north of Woodrolfe Road, a medieval road linking Tollesbury with Woodrolfe Creek and the nearby marshes, and southwest of a series of Late Iron Age or Roman 'red hills'. Excavations at the site revealed a medieval ditch which was likely the product of agricultural activity, and which also produced a small amount of Late Iron Age and Roman pottery. A modern posthole, an undatable pit and a natural feature were also uncovered.
