Site Use and It is understood that the site is proposed for the development of residential properties comprising of two Development semi-detached dwellings. Summary The site is bounded to the north by two dwellings which front onto Ansely Common (B4114), to the east by a local shop and west by residential properties. To the south lies open land, beyond which is a playground. Geological mapping indicates the site to be underlain by Pennine Middle Coal Measures (Secondary A Aquifer); no superficial deposits are recorded as being present across the site. Geoenvironmental A number of surface water features are present within 1km of the site including the Bar Pool Brook and Setting numerous drains and ponds. It is considered based on the readily available information that groundwater flows towards the East (i.e. towards Bar Pool Brook). Overall, the environmental sensitivity of the site is considered to be Low to Medium. The potential exists for localised residual contamination to be present, predominantly associated with the historical use of the site for a small scale engineering works. Where landscaped areas will exist in the proposed residential development site users may be exposed to residual contamination which might be present within the subsurface. The permeable nature of the underlying bedrock geology means it is likely to easily transmit Preliminary Risk contamination. However as the current site use and proposed site use are considered to represent a low Assessment risk of contamination generation, it is considered unlikely that any significant impact on controlled waters will occur. There is the potential for elevated concentrations of sulphate to be present in Made Ground that could impact building foundations. However, this can be managed by appropriate classification of concrete. Buildings will require appropriate concrete foundations and water supply pipes. Based on the information contained in this report and with due regard to the re - development of the site for a residential use, it is the opinion of WSP that the site represents a low risk with respect to contaminated land liability issues. As with any development site, an initial phase of ground investigation will be required to inform the development. The re-use of any materials from an off-site source or on-site materials would require Recommendations regulatory approval or management under the CL:AIRE code of practice, which would require the preparation of a materials management plan and the chemical and geotechnical characterisation of the materials. Prior to any redevelopment an asbestos demolition survey will be required. In the event that the site is not redeveloped and is used for on-going operation of the site an asbestos management survey and asbestos management plan will be required. 00033031-R01 Geo-environmental Desk Study, 45 Ansley Common 3 1 INTRODUCTION 1.1 AUTHORISATION WSP Environment & Energy (WSP) was commissioned by Andrew Large Surveyors Ltd on behalf of Annie Green to undertake a Geoenvironmental Desk Study of a site located at 45, Ansley Common, Nuneaton, Warwickshire. A site location plan is included as Figure 1. 1.2 AIMS AND OBJECTIVES The works are required to qualitatively assess the potential geotechnical and environmental risks associated with the proposed development. This report will be used to inform the planning application process. The general limitations to the nature of the assessment are outlined in the Notes on Limitations presented in Appendix A. 1.3 DEVELOPMENT DETAILS It is understood that Annie Green considering the redevelopment of the site, it is intended that this land will be developed as two semi-detached residential dwellings with small gardens. The site is currently occupied by a small industrial warehouse building. No planning conditions or proposed development layout are currently available for the site. 1.4 SCOPE OF WORKS Site walkover to provide a visual assessment of the site and assess potential environmental concerns both on-site and in relation to nearby receptors. Review of historic Ordnance Survey maps - to assess the historical usage of the site. Review of information regarding the geology, hydrogeology and hydrology of the site and surrounding area to assess ground conditions and the presence of sensitive environmental targets. Obtain and review a Coal Mining Report. Obtain and review Landmark Envirocheck database information regarding the presence of landfill sites and waste treatment facilities, fuel station entries, contaminated land register entries, pollution incidents to controlled waters, discharge consents and abstraction licenses etc. Liaison with the relevant regulatory authorities (if deemed necessary) following the review of the Envirocheck data to obtain further details on any nearby past and present waste disposal sites, licensed water abstractions and pollution incidents. Prepare a qualitative conceptual site model to assess whether any sources of contamination (if any) pose a significant risk to the investment and future redevelopment. This will be undertaken in accordance with current UK guidance on risk assessment, and will review the presence of source - pathway – receptor relationships (pollution linkages) in the context of the site and surrounding area. 00033031-R01 Geo-environmental Desk Study, 45 Ansley Common 4 2 SITE LOCATION AND SETTING 2.1 SITE DETAILS Table 2.1 – Site Details Site Address 45 Ansley Common, Nuneaton, Warwickshire, CV10 0PP Ordnance Survey Grid Reference 431910, 293350 Planning Application Boundary 0.03 hectares The site is rectangular in shape and is located approximately 4km northwest of Site Location Nuneaton Town Centre in a predominantly residential area. Current Use The site is currently occupied by a small industrial warehouse building. The site is bounded to the north by two dwellings which front onto Ansley Common Surrounding Land Use (B4114), to the west by residential properties, to the east by a local shop and to the south by open land, beyond which lies an allotment and a playground. The boundary of the site area is presented on Figure 1. 2.2 SITE RECONNAISSANCE 2.2.1 General A walk over survey of the site was carried out by Kerry Murray of WSP on Thursday 2nd August 2012. All external and internal areas of the site were accessible. Selected photographs of the site are presented in Appendix B. 2.2.2 Topography and Surface Cover The topography of the area is generally flat. The site is covered completely by the warehouse building with no external areas. The adjacent roadway to the east and south comprise a hardstanding shared access. We understand that the shared access falls outside the proposed planning application boundary. 2.2.3 Site Use and Buildings The subject site comprises a 0.03 hectare plot of land which is accessed from the adjacent Ansley Common Road. The site is roughly rectangular and comprises a single storey brick warehouse with steel frames supporting the roof. Anecdotal evidence provided by the client suggests that the warehouse has been previously used for small scale engineering of metal parts, a butchers and window manufacturing. The warehouse is currently used for storage of goods including suntan cream, washing powder, cleaning fluids (e.g. bleach) and electrical kitchen goods. Two smaller rooms are present in the north of the warehouse building and are currently used for an office and a toilet. A battery powered forklift truck is used to transport the goods around the warehouse. The site appears to be heated by gas boiler and blower, the site contact confirmed that the heating was not currently in use. During the site walkover, no back-up generator or oil storage was noted during the site walkover. 2.2.4 Waste and Fly Tipping Based on the site walkover, no significant waste streams are currently being produced at the site. Evidence of some fly tipping (approximately four bags of general household waste) was noted within the southern boundary of the site, located on the shared access driveway. 00033031-R01 Geo-environmental Desk Study, 45 Ansley Common 5 2.2.5 Observations of Contamination No evidence of contamination was noted during the site inspection (e.g. staining, vegetation distress). 2.2.6 Bulk Fuel Storage No evidence of either above or below ground tanks (e.g.
