30th November 2015 The University of Reading c/o Mr Imran Shah Assistant Project Manager Parsons Brinckerhoff Management Services - Sustainable Building Solutions South URS Building, Whiteknights Campus The University of Reading Shinfield Road Reading RG6 6AX Dear Imran, URS Building, The University of Reading, Whiteknights Campus – Phase 2 Bat Surveys Further to my colleague Emma Heath’s letter dated 13th February 2015, addressed to Mr Paul McAteer, which detailed the results of an Ecological Appraisal and Bat Building Inspection alongside arising recommendations, I am writing to provide the full results of the Phase 2 Bat Surveys at the URS Building. The following should be read in conjunction with the site Ecological Appraisal and Bat Building Inspection letter (EPR, 13th February 2015). This letter provides a summary of the methods and results of Phase 2 Bat Surveys carried out to assess the presence/likely absence of bats roosting in the building and using the site. An evaluation of the potential impacts of the proposals is described and recommendations provided for required mitigation in order for redevelopment to proceed in line with applicable nature conservation legislation and policy. As the full extent of the redevelopment plans have not yet been finalised, the advice provided within this letter should help inform the development of the proposals. If the final proposals extend beyond works including renovation works, cosmetic alterations such as the replacement of cladding and enclosing the existing under croft to increase the amount of usable space within the building, the advice provided within this letter may need to be updated and further surveys may need to be conducted. Project Background The URS building is situated at the centre of the University of Reading Whiteknights Campus (National Grid Reference: SU 7332 7172) within a complex of office and teaching blocks, interspersed with amenity gardens and ornamental planting (Map 1). The campus lies to the south- west of Reading city centre within a largely residential urban setting (Map 2). For full details of habitats and ecological features present at the Site please refer to the Ecological Appraisal and Bat Building Inspection letter. Current proposals entail renovation works, cosmetic alterations such as the replacement of cladding and enclosing the existing under croft to increase the amount of usable space within the building. In order to identify potential ecological constraints and opportunities associated with the plans, a full Ecological Appraisal of the Site was completed in January 2015 and the potential Zone of Influence of current proposals was assessed. As part of this assessment, existing biodiversity records within 5 km of the site were requested (Map 3). During the Ecological Appraisal and Bat Building Inspection, to determine the potential for the Site to support Protected Species, features suitable to support roosting bats were recorded on the building (Map 1 and Map 4) and any features suitable to support or evidence of any other Protected Species was looked for. Given the results of the Ecological Appraisal and Bat Building Inspection, it was recommended that further species specific Phase 2 survey works be completed in order to fully assess the potential impacts of current proposals at the Site. Zone of Influence In order to identify the full extent of the potential ecological implications associated with redevelopment of the Site, I have considered the likely Zone of Influence (ZoI) of the proposals (IEEM, 2006; refer to Appendix 1). Taking into account the type and scale of current proposals, I consider that the potential ZoI of the scheme, for the majority of biophysical changes, is likely to extend only to the existing building and immediately surrounding university grounds and will not extend beyond the redline Site boundary (Map 1). The proposed works are only due to occur within the redline Site boundary. For bats, it is considered that, in most cases, the ZoI of the redevelopment proposals is unlikely to extend beyond the redline Site boundary and immediately adjacent habitats, except where changes to onsite and boundary habitats and environmental conditions may impact upon bat roosts within the local area, for example due to increased lighting or loss of commuting/foraging areas upon which local roost(s) may be dependant. Relevant Guidance, Legislation and Policy Legislation and policy relevant to the Phase 2 surveys is set out under Appendix 1 and summarised below. In undertaking this assessment, I have referred to best practice guidance, including that detailed within the Guidelines for Ecological Impact Assessment (EcIA) in the United Kingdom (IEEM, 2006) and the Bat Conservation Trust (BCT) Bat Surveys, Good Practice Guidelines (BCT, 2012). In preparing my recommendations, due consideration has been given to relevant wildlife legislation, planning policy and nature conservation priorities, both national and international, including: The National Planning Policy Framework (NPPF); National and international wildlife legislation, including the Conservation of Habitats and Species Regulations 2010 (the ‘Habitats Regulations’) and the Wildlife and Countryside Act 1981 (as amended); Biodiversity conservation priorities under the Natural Environment and Rural Communities (NERC) Act 2006, and Reading Biodiversity Action Plan (BAP); and Nature conservation policy under the local planning system, namely that detailed within the existing Reading Borough Council Core Strategy (2008) (in place ahead of an emerging Local Plan document). Methodology Methods employed during Phase 2 survey work at the Site are set out under Appendix 2 to this document and summarised below. Bats Phase 2 bat survey work entailed the completion of a dusk emergence survey on 17th August 2015 and a pre-dawn re-entry survey on 28th August 2015. The results of these surveys are summarised in Table 1. Bat surveys were completed in line with best practice guidelines, including those detailed under the Bat Survey, Good Practice Guidelines 2nd Ed. 2012 (BCT). During surveys, five surveyors were positioned at previously-identified vantage points, with uninterrupted sight lines of the building, to observe any bats as they exited/re-entered roosts and record any bat activity in its vicinity. Each surveyor was equipped with a Batbox Duet or a Patterson 240x bat detector and a Site map on which to record results. For each bat pass, the time, species, behaviour and direction of travel was noted, where known. Impact Assessment and Mitigation Methodology The below assessments of likely ecological impacts of redevelopment proposals have been reached based on guidance within the IEEM EcIA Guidelines (2006) and best practice guidance. The current proposals have been considered in order to identify any potential significant impacts (positive or negative) on bats and other species and how these relate to applicable legislation and policy, referred to Appendix 1. Where potential significant impacts have been identified, wherever possible, a variety of mitigation measures have been proposed within the below recommendations section in order to reduce or eliminate potential significant negative impacts and provide appropriate enhancement measures for ecological features within the Site. Results and Evaluation Bat Activity Survey Results Bat activity survey results are shown on Map 5 and Map 6 and summarised below in Table 1.
