Abstract: |
The primary aim of the archaeological mitigation was to record and advance understanding of the significance of any archaeological remains within the site prior to their destruction during construction work. According to the agreed scheme of work (Mayo 2023), this was to be realised through the achievement of the following objectives:
To establish the spatial extent date, character, condition and significance of the archaeological activity in the proposed investigation areas;
To recover information relating to the nature and function of past human activity represented by the surviving archaeological remains;
Excavate and record identified archaeological features and deposits to a level appropriate to their extent and significance;
Assess the potential for survival of environmental evidence;
To interpret the nature of human activity at the site and to place the site within its local, regional and national context as appropriate;
Assess the site formation processes and the effects that these may have had on the survival and integrity of the archaeological features and deposits;
Undertake sufficient post-excavation assessment to confidently interpret identified archaeological features;
Undertake sufficient post-excavation assessment and analysis of artefacts and environmental samples to interpret their significance;
Report and publish the results of the excavation and post-excavation analysis and place them within their local and regional context;
Compile and deposit a site archive at a suitable repository and to provide information for the local HER to ensure the long-term survival of the excavated data.
It was proposed to excavate two trenches, each 20m x c.1.8m; a contingency of a further 10m of trenching was included should this be necessary to clarify the results of the initial findings. Topsoil and any other overburden would be removed by a 360° type machine. A toothless ditching bucket was to be used to expose archaeologically sensitive levels under constant archaeological supervision. Where archaeological features were either certainly or probably present, the stripped areas were to be cleaned using appropriate hand tools. Sufficient of the archaeological features/deposits exposed would then be excavated or sampled by hand to satisfy the aims outlined above, without compromising the integrity of any archaeological features or deposits which may warrant preservation in-situ, or which might better be excavated under the conditions pertaining to full excavation. The work was to be carried out in accordance with the relevant guidelines of the Chartered Institute for Archaeologists The potential and significance of any such deposits located were to be assessed according to research priorities such as those set out in Historic England Research Agenda (HE 2017) or more local or thematic research priorities such as Research and Archaeology Revisited: a revised framework for the East of England (Medlycott 2011). The evaluation demonstrated that the site had been previously extensively disturbed. It appears that a large part of the southern and central area of site had been previously stripped of topsoil and subsoil down to the natural geology. Made ground was then dumped on this geology and then a thin topsoil was placed on top of this. In the northern part of the site, was a large modern cut or pit over 8m in length and 1.20m deep and filled with modern building materials. It truncated a small area of buried soil in the north-west of the site which sealed the natural geology. No archaeological features were recorded in this area and based on the results of this trenching, the whole site has low archaeological potential. |
