This archaeological desktop assessment was commissioned by Carillion Utility Services on behalf of EDF Energy to assess the likely impact of the construction of a c. 11.5km power cable from Sundon Grid (NGR TL 0327 2679) to Leighton Buzzard (NGR SP 9278 2507). Evaluation of the archaeological, historical, aerial and cartographic evidence shows the proposed cable crosses an area of prehistoric and Romano-British activity, areas of Medieval settlement, ridge and furrow, ancient woodland and routes, and areas of quarrying for sand and gravel. Currently, the majority of the route consists of agricultural land, with numerous boundaries pre-dating the inclosures of the 18th and 19th centuries.
