Ltd (G&J) was commissioned by Harris McCormack Architects to carry out an Interpretative Desk Study for a site located at Sconsborough Hill Farm, Knossington, Oakham. The purpose of this report is to collate and interpret information pertaining to the site from a desk-based review of available data. The scope of the study is as follows: • To determine the environmental setting of the site and its surroundings in terms of location, topography, ground conditions and land use; • To discuss the geology, hydrogeology and hydrology at, and in the vicinity of, the site; • To determine the site history and that of the surrounding area; • To assess potential contamination issues pertaining to the site with consideration of the site’s current and historic use; • To develop an initial Conceptual Site Model (CSM) linking sources of potential contamination with pathways and receptors; • To produce a Preliminary Risk Assessment for contamination in accordance with CLR11 – Model Procedures for the Management of Land Contamination; • To provide recommendations for further work and / or mitigation measures; and • To support any planning applications for development of the site. 1.1 Terms and Conditions This report has been prepared for Harris McCormack Architects in consideration of the current use of the site and a future residential development. Much of the environmental information relates to the site in its present state and should not be used in a different context without reference to G&J. 1.2 Sources of information The following sections describe the environmental setting of the site, the site history and the anticipated ground conditions based on information taken from a variety of sources, including; • Site Inspection; • Current maps and plans; 1 Harris McCormack Architects Interpretative Desk Study GJ203 May 2020 Sconsborough Hill Farm, Knossington Interpretative Desk Study • Site photographs (Appendix A); • Geological maps and records; • Environmental data (Groundsure) reports (Appendix B); • Historical maps (Appendix C); • Website of relevant authorities and organisations such as The British Geological Survey, the Environment Agency, Natural England and Historic England Much of the information reviewed as part of this assessment is contained within the historical maps and data reports obtained from Groundsure.
