A fluxgate gradiometer survey of land east of Warren Lane, Stanway, Colchester, was undertaken by ASE Archaeology in February 2016, prior to the deterimation of a planning application for residential development (CBC planning application 152826). The survey area consisted of three sites totalling approximately c.2.6 hectares of pasture land, bounded by hedgerows and wire fences.<1> The most compelling evidence for possible archaeological features was represented by a positive anomaly on higher gravels in the east of the site. This anomaly may represent part of a rectilinear cut feature such as an infilled enclosure ditch. Further moderate positive anomalies representing possible ditches correspond to two features seen on aerial photography. These features appear to relate to a possible palaeochannel system flowing into the Roman River valley. A large area of weak positive magnetic enhancement corresponds to the broad area of the features noted on aerial photography. Several weak discrete and linear positive anomalies may relate to cut features such as pits and ditches but a natural origin cannot be discounted. Linear anomalies may also relate to plough scarring.
