LC-260_SBDC&CDC_HRA_Screening_8_030117JE.docx Executive Summary E1 This HRA report has carefully considered the conservation objectives of European sites that might be associated with activities and projects as part of the Chiltern District and South Bucks District ‘Local Plan Green Belt Preferred Options Public Consultation October – December 2016’ (GBPOPC). E2 Lepus identified nine European sites that lie within 15km of the boundaries of both districts. E3 The following nine sites feature in this HRA report: • Aston Rowant SAC • Burnham Beeches SAC; • Chilterns Beechwoods SAC; • Richmond Park SAC; • South West London Waterbodies SPA; • South West London Waterbodies Ramsar; • Thames Basin Heaths SPA; • Thursley, Ash, Pirbright & Chobham SAC; and • Windsor Forest & Great Park SAC. E4 A number of recognised threats and pressures are associated with these sites as identified by Natural England. This HRA screening report explores the extent to which, if any, the proposals associated with the release of Green Belt for the purposes of residential and employment development will exacerbate or alleviate these threats and pressures. E5 It is considered that proposed development in the GBPOPC will have a likely significant effect on Burnham Beeches SAC due to potential recreational disturbance impacts associated with public access, and potential impacts associated with air quality.

This is a requirement of Regulation 102 of the Conservation of Habitats and Species Regulations 20101 (the Habitats Regulations). 1.1.2 The following European sites were identified using a 15km area of search around the Chiltern and South Bucks districts, as well as including sites which are potentially connected (e.g. hydrologically) beyond this distance: • Aston Rowant SAC; • Burnham Beeches SAC; • Chilterns Beechwoods SAC; • Richmond Park SAC; • South West London Waterbodies SPA; • South West London Waterbodies Ramsar; • Thames Basin Heaths SPA; • Thursley, Ash, Pirbright & Chobham SAC; and • Windsor Forest & Great Park SAC. 1.1.3 Whilst Ramsar sites are not European sites, NPPF
