A total of 46 test trenches were excavated across the proposed development site. Each trench measured 1.8m in width, and in total, 1,140m of linear trenches were excavated. The topsoil ranged in depth from 0.4m to 0.98m and from a mid-brown clayey silt to an orangish brown clayey silt. The natural varied from a grey and brown gravelly clay to an orange clay to a mottled grey and brown clay.
Several modern features were noted in the trenches in the form of field drains, stone drains, service ducts, and building foundations. The possible ring-ditch identified in the geophysical survey (25R0166: Murphy 2025) was not identified in the targeted trench. However, a slightly raised mound, with gravel directly beneath the sod, could explain the anomaly on the geophysical survey. No archaeological features or deposits were observed or exposed within any of the trenches, and no archaeological artefacts were recovered.
