The CIR comprised two areas (C31079 and C31080) of c. 0.011ha and 0.014ha respectively, laid out using reconnaissance information gathered during ES, remote sensing and geophysical surveys and the subsequent phases of evaluation and investigation. Specific construction impacts (e.g. the temporary and permanent works required in the area) were considered. This evidence-led approach also drew upon site-specific and local topographical and geological information as well as known areas of past human activity within the immediate vicinity. The extent of the area for CIR was determined based on designs for the permanent works. Headland Archaeology ensured that the archaeological investigations were undertaken in an organised, efficient, and professional manner and had full regard for the safety of all personnel and visitors on site. This included but was not limited to any effects the archaeological evaluation had on the daily operations of the landowner, other contractors engaged in the construction of HS2 Phase One and members of the public. The earliest activity in C31079 comprised two stake holes and a ditch, all cut into the natural geology. These were sealed by a dark earth deposit containing occasional Roman finds, which covered the entire site. Cutting the dark earth deposit which sealed the earlier late Iron Age and early Roman features were structural features dated as early to late Roman. These Roman features included the remnants of two possible wall foundations which likely relate to structural remains previously recorded in C31059B. A small oven, possible wall foundation, and ditch were also recorded within C31079. Excavation in area C31080 uncovered a ditch, a post-hole, and an irregular pit, all cut into the natural geology. As in C31079, these features were overlain by a dark earth deposit. No further features were identified within this layer, which was ultimately sealed by topsoil. The activity with both areas was shown to correspond to earlier phases, with C31080 contributing further information as to the land use of the central area of the site.
