The proposed development area is located on the south-western boundary of the settlement of Cheslyn Hay, on the east side of the Wolverhampton Road (B4156), centred on NGR SJ 9710 0640 and comprises a site currently used as a quarry. The proposed development area covers 25.7ha. Most of the proposed development area, with the exception of a field immediately south of the existing cemetery on Wolverhampton Road, has an extant planning permission for minerals use. The effects of both schemes on archaeology are considered in this report. There is little evidence for prehistoric or Roman activity within or near the proposed development area. The proposed development area is located approximately 2 kilometres south of the alignment of Watling Street Roman road. There is, however, no evidence for associated Roman activity in the area. A moated site, now destroyed and located about 150 metres west of the proposed development area, is the only evidence for medieval activity within or near the proposed development area. There has clearly been coal working within the proposed development area. The evidence indicates that this was probably of post medieval date. However, the entire proposed development area, with the exception of a field immediately south of the cemetery, measuring about 2ha, and a small area north of what was Campions Wood itself, to be retained as open space, has been quarried away. It is considered; therefore that the potential for the proposed development to impact upon archaeological remains of any date or type is negligible. Two historic features survive just within or immediately adjacent to the edge of the proposed development area. These are part of the line of Pinfold Lane and the line of the Wyrely Bank branch of the Wyrely and Essington Canal. The features will be preserved in situ by the proposed development The study has revealed that no statutory designated sites (e.g. Scheduled Monuments, Listed Buildings) are present within the application site. The closest designated site is numbers 14-16 Dundalk Road, listed at Grade II, located about 450 metres from the proposed development area. No statutorily designated or locally listed feature, or it’s setting, will be affected by the proposed development. Given that the proposed development area in general has a low potential for the survival of significant archaeological remains, and that the site has been largely quarried away, thus removing any archaeology, it is recommended that no further work be carried out with regard to archaeology in connection with proposed development at this site.
