truncated later deposits. However, there remains potential that more substantial remains might havesurvived.Impacts to any archaeology havethe potential to occur during any intrusive ground works beneath theexisting ground level, such as excavation of the basement, piling and service trench excavation and anyearth moving for levelling. In order to mitigate any likely potential impact on potential furtherprehistoric, Roman, medieval and post‐medieval buried heritage assets, further informationis requiredand as such, an intrusive archaeological evaluation will be undertaken. Followingg consultation withSouthwark Council’s Principal Archaeologistan Outline Written Scheme of Investigation (WSI)) has beenprepared. This specification presents a methodology forthe intrusive work, and forms the basis for anarchaeological contractor to complete a detailed WSI. The intrusive work will entail excavating two trialtrenchesof 10m by 2m at the northeast and southeast corners of thee Site. The results of theevaluationwill be subject to a post‐excavation assessment, and a report documenting the fieldwork willl present adigest ofinformationn on the character and significance of any buried heritage assets located within theSite. Thefindings ofthe archaeological evaluation will allow the appropriate mitigation measures forthe construction phase, as necessary, to be scoped and delivered. These will be secured by anappropriately worded condition on any planning consentand could, for example, , include anarchaeological watching brief during ground works.2.7 Ground Remediation WorksFull access to the swimming pool area was not possible as part of thee ground conditions assessment insome areas due to degradation of the building and a large number off pigeon faeces and algae on thefloor. However, the majority of the t building was inspected. Further tests to identify any unknowncontamination will be carried out following the completion of removal of slab and swimmingpool,foundations.A suitable thickness of clean topsoil will be placed in areas of soft landscaping to reduce the likelihood ofplants coming into direct contactt with any residual contamination. The potential for existing groundcontamination to pose a risk to human health and groundwater oncee the Development is completed andoperational will be minimal.The areaa around theElephant and Castle sustained relatively high levels of bombb damage during WorldWar II. Itwill be necessary for anunexplodedd ordnance assessment to t be undertaken.St Mary’s Residential Detailed Planning Application May 201210
