The Benhall facility currently accommodates approximately 5700 employees, although due to the nature of the business undertaken and the constant 24-hour operation of the site, these staff are not all present concurrently. The existing NAP Benhall site comprises an out of town B1 office land use, located to the west of Cheltenham, which was developed at the beginning of the 21st century, to ensure GCHQ could continue to evolve and stay ahead of the ever intensifying demands for intelligence and security advice in the UK. The latest phase in the development of GCHQs business is therefore for the operations in Cheltenham to be consolidated onto one site. A Scoping Report was prepared and issued to Gloucestershire County Council (GCC), following a meeting with their officers in September 2008. The scope set out the principal issues that the TA would consider and established the relevant study area on which the analysis would be based. This was further informed by an extensive period of consultation which sought to engage the local community and ensure that they were fully informed of the proposed relocation programme. From a transport perspective, this approach has put transport provision at the heart of the design by providing the necessary physical environment for the promotion of sustainable travel incentives, whilst retaining the security requirements of GCHQ. Particular emphasis has been placed upon sustainable transport modes, which are accessible to the employees and users of the site and a comprehensive review of walking, cycling and public transport facilities has been undertaken as part of the TA. GCHQ have made considerable investments into the local infrastructure and services available in the vicinity of the site in recent years and are committed, through the evolution and management of their Travel Plan, to promote the use of these other modes in preference to the private motor car. In terms of vehicular trips, it has been recognised that as the existing 800 staff are already travelling to and from the Oakley site, that the relocation onto NAP Benhall will not be expected to result in the creation of any additional trips, but will redistribute the existing movements. In order to inform this, a detailed trip generation and trip distribution assessment has been undertaken, which has considered the quantum of existing trips associated with Oakley that should be substituted for the redistributed trips which will travel to and from NAP Benhall, following the relocation of the staff. As part of the scoping discussions with GCC, analysis was presented of the relative expected change in trips on the local highway network in the vicinity of the NAP Benhall site, such that the study area could be confirmed. This subsequently consisted of the primary connection points between the site and the A40 Gloucester Road and Princess Elizabeth Way. A range of capacity appraisals have been undertaken to consider the effective operation of junctions at each of the identified locations, which have confirmed a negligible impact on existing performance across the study area. Minor modifications will however be made to the Telstar Way Roundabout to minimise the level of queuing on the respective arms, whilst right turners and U turners will be allowed from the eastern arm of the roundabout. An assessment of road safety has also been undertaken by analysing the historic reported Personal Injury Accidents (PIA). This has identified that there have not been any particular clusters or trends in road safety incidents. ii Integrated Accommodation Services NAP Benhall New Build Table of Contents 1 Introduction......................................................................................... 1 1.1 Purpose ............................................................................................................................ 1 1.2 Site Location and Background ......................................................................................... 1 1.3 Structure........................................................................................................................... 1 2 Development Proposals ..................................................................... 3 2.1 Development Site ............................................................................................................. 3 2.2 Schedule of Development ................................................................................................ 3 2.3 Site Access....................................................................................................................... 4 2.4 Hours of Operation ........................................................................................................... 5 3 Legislation and Planning Policy Guidance ......................................... 8 3.2 Planning Policy Guidance 13 (PPG13) ............................................................................ 8 3.3 The Draft Regional Spatial Strategy for the South West 2006 - 2026.............................. 9 3.4 Gloucestershire Structure Plan Second Review 2011...................................................... 9 3.5 Gloucestershire Local Transport Plan 2006 – 2011 ....................................................... 10 3.6 Cheltenham Borough Local Plan Second Review (Adopted July 2006)......................... 11 3.7 Cheltenham Transport Plan 2000/2001 to 2005/2006 ................................................... 12 4 Sustainable Transport ...................................................................... 14 4.1 Introduction..................................................................................................................... 14 4.2 Pedestrian Links............................................................................................................. 15 4.3 Cycle Links .....................................................................................................................18 4.4 Public Transport Accessibility......................................................................................... 19 4.5 Travel Plan Summary..................................................................................................... 21 4.6 Overall Summary............................................................................................................ 23 5 Baseline Conditions.......................................................................... 24 5.1 Existing Highway Network.............................................................................................. 24 5.2 Transport Assessment Study Area................................................................................. 24 5.3 Transport Assessment Data Sources............................................................................. 25 5.4 Local Highway Network.................................................................................................. 26 5.5 Wider Highway Network ................................................................................................. 27 5.6 Baseline Junction Capacity Analysis.............................................................................. 28 6 Road Safety...................................................................................... 35 6.1 Personal Injury Accident (PIA) Data............................................................................... 35 iii Integrated Accommodation Services NAP Benhall New Build 6.2 Local Highway Network.................................................................................................. 35 6.3 Wider Highway Network ................................................................................................. 36 6.4 Summary .......................................................................................................................
