and • A main report – consisting of two volumes: ȃ Volume 1: Introduction to the Environmental Statement and Proposed Scheme which provides an introduction to HS2, an overview of the hybrid bill process and the environmental impact assessment (EIA) methodology, an introduction to consultation and engagement, the main strategic and route-wide alternatives considered; and ȃ Volume 2: Includes 26 Community Forum Area (CFA) reports, each with a separate corresponding set of drawings, which together provide the assessment of local environmental effects. An assessment of the effects of the Proposed Scheme on a route-wide basis is presented in Report 27. HS2 Ltd set up 26 community forums along the line of route of the Proposed Scheme, as a regular way of engaging with local communities.1 Volume 2 of this draft ES supports this engagement strategy by providing a draft ES report for each CFA. This is a report for the Dunsmore, Wendover and Halton area, CFA10. The draft ES has been written in a clear and accessible manner; however, on occasion it has been necessary to use technical terms. Given this, a glossary of terms and list of abbreviations for all draft ES documentation is provided. 1 Details of these community forums are provided on the HS2 Ltd website at http://www.hs2.org.uk/have-your-say/forums/community-forums.

Phase One (the Proposed Scheme), the subject of this draft ES, would involve the construction of a new railway line of approximately 230km (143 miles) between London and Birmingham that would become operational by 2026; with a connection to the West Coast Main Line (WCML) near Lichfield and to the existing HS1 line in London. The Phase One route and the 26 CFAs are shown in Figure 1. 1.1.3 On opening, Phase One would run up to 14 trains per hour (tph). HS2 trains would be up to 400 metres (m) long with 1,100 seats during peak hours. Beyond the dedicated high speed track, these high speed trains would connect with and run on the existing WCML to serve passengers beyond the HS2 network. A connection to HS1 would also allow some services to run to mainland Europe via the Channel Tunnel. 1.1.4 Phase Two would involve the construction of lines from Birmingham to Leeds and Manchester; with construction commencing around 2027, and planned to be operational by 2033. After Phase Two opens, it is expected that the frequency of train services on some parts of the Phase One route could increase up to 18tph. 1.1.5 The Government believes that the HS2 network should link to Heathrow and its preferred option is for this to be built as part of Phase Two. However, the Government has since taken the decision to pause work on the Heathrow link until after 2015 when it expects the Airports Commission to publish its final report on recommended options for maintaining the country’s status as an international aviation hub. 1.2 Purpose of this report 1.2.1 This report presents the likely significant environmental effects as a result of the construction and operation of Phase One HS2 (the Proposed Scheme) that have been identified to date within the area of Dunsmore, Wendover and Halton (CFA10).
