Site Event/Activity record ESF22288 - Evaluation - Old Grammar School Playing Field, Bungay

Trial trench evaluation was carried out on the site of a proposed new community centre. Six trenches (total area 216 sq m) were excavated to a depth of 0.85m-1.9m, representing approximately 4% of the area most affected by the proposed development. The natural stratum was sand and gravel (of glaciofluvial or river terrace origin) with a slight downward slope from west to east. It was overlaid by generally thin and discontinuous subsoil deposits of loose sand and gravel. Two undated linear features were recorded in the north-western part of the site, cutting the natural sand and sealed by a subsoil deposit. It is unclear therefore whether these features were of natural or man-made origin. Subsoil deposits were overlaid by worked soil horizons and a buried topsoil layer. This was sealed by levelling dumps of clay, sand and soil that were spread over the lower-lying areas of the site when the grammar school playing field was created (S1).
