Chapter 4 described existing environmental conditions. 3.1.1.2 The current extent of the Scheme and the Scheme Study Area is shown in Figure 3-1. This is the area within which all the Scheme options described in Chapter 8 are located. Further details of the coverage of the A27 transport model is provided within the A27 Arundel PCF Stage 2 Further Consultation Combined Modelling and Appraisal Report2. 3.1.1.3 The Scheme is located in Arun District within West Sussex on the south coast of England. The Scheme is primarily within the parishes of Walberton and Arundel but extends into the neighbouring parishes of Slindon and Crossbush and Lyminster. The northern half of Arun District falls within the South Downs National Park (SDNP). The SDNP Authority is the planning authority for the SDNP. 3.2 Locality 3.2.1.1 The small historic market town of Arundel is located within the Arun District of West Sussex in the South of England. The town is positioned in a steep valley on the border of the SDNP. The SDNP covers an area of 1600km2, extending from Winchester in the west to Eastbourne in the east3. The location of Arundel in a wider south-east England geographical context is presented in Figure 3-2. 3.2.1.2 The largest population centre in the surrounding region is the city of Brighton and Hove, located approximately 29km to the east of Arundel, with a population of over 270,0004. Other nearby major urban areas include Littlehampton to the South, Worthing to the East, Bognor Regis to the south- west and Portsmouth and Chichester to the west. 1 Unless otherwise specified, the baseline information relating to transport conditions is based on the year 2015 2 HE551523-WSP-GEN-SWI-RP-TR-00017-P03 – A27 Arundel Bypass, PCF Stage 2 Further Consultation Combined Modelling and Appraisal Report (July 2019) 3 https://www.southdowns.gov.uk 4 https://www.nomisweb.co.uk (based on 2011 census) Page 3-5 August 2019 Interim Scheme Assessment Report A27 Arundel Bypass – PCF Stage 2 Further Consultation Figure 3-1 - Scheme Extents and General Scheme Study Area Page 3-6 August 2019 Interim Scheme Assessment Report A27 Arundel Bypass – PCF Stage 2 Further Consultation Figure 3-2 – Wider Geographical Context 3.2.1.3 There are a number of established major employment areas within the region, one of which is the Gatwick Diamond, a diamond-shaped geographical area, with Gatwick Airport at its centre, comprising around 45,000 businesses, many of which are global companies. The Gatwick Diamond contributes £24bn Gross Value Added (GVA5), to the UK economy and performs well above the national average on a range of different economic indicators, such as its levels of productivity, its share of high-skilled jobs, and its track record at attracting foreign investment6. The Gatwick Diamond has strong commuter links to towns along the south coast. Other major employment areas are situated in the cities of Portsmouth and Brighton and Hove for example, as well as the large town of Worthing. 3.2.1.4 Tourism is a key driver of the economic activity in the region, with West Sussex as a county receiving over 17 million visitor days per year. This contributes over £500 million to the local economy7 . 5 Regional Gross Value Added is the value generated by any unit engaged in the production of goods and services (https://www.ons.gov.uk/economy/grossvalueaddedgva) 6 http://www.gatwickdiamond.co.uk/media/95386/Gatwick-Diamond-Business-Plan-2018-to-2021.pdf 7 The GB Day Visitor Statistics 2015, Visit Britain Page 3-7 August 2019 Interim Scheme Assessment Report A27 Arundel Bypass – PCF Stage 2 Further Consultation 3.2.1.5 Pockets of deprivation are found within the county of West Sussex, especially in coastal areas. These areas suffer from a skills shortage and lack of accessibility to higher value employment sectors within the county. Some of the most deprived areas are the wards of River and Ham in Littlehampton, with three Lower Super Output Areas (LSOA’s8) in these two wards falling within the UK’s top 10% most deprived areas9. As a result of this, regeneration is underway, not just in Littlehampton, but in Bognor Regis, Shoreham and Newhaven. In Bognor Regis for example, there are proposals to develop a creative/digital hub through the implementation of 108,500m2 of employment space, generating over 4,000 jobs. 3.2.1.6 Arundel has a population of approximately 3,500 people, with an average age of 47.1 years4. The town is a popular tourist destination for its location on the border of the SDNP and for its heritage which includes three scheduled monuments, one of which is Arundel Castle and many listed buildings including Arundel Cathedral. 3.2.1.7 Employment within Arundel itself is focused on the tourism industry, with restaurants, shops, and a museum featuring alongside the historical attractions. Situated just outside of Arundel are a number of industrial areas. These include Ford Lane, Ford Road and Rudford Industrial Estates all of which are situated adjacent to Ford Road. 3.3 Existing Transport Network 3.3.1.1 This section describes the existing transport network within the wider region and the local area, including the provision for highway, public transport, and Walking, Cycling and Horse Riding (WCHR) users. 3.3.2 Highway network 3.3.2.1 The location of the scheme in the context of the wider strategic network is depicted in Figure 3-3. 8 A geographical boundary used in the production of statistics collected via the UK census 9 WSCC Public Health Research Unit - West Sussex Joint Strategic Needs Assessment Briefing - Indices of Deprivation 2015 (Arun) (https://jsna.westsussex.gov.uk/assets/core/Briefing-Indices-of-Deprivation-2015.pdf) Page 3-8 August 2019 Interim Scheme Assessment Report A27 Arundel Bypass – PCF Stage 2 Further Consultation Figure 3-3 – A27 in the Context of the Wider Strategic Road Network Page 3-9 August 2019 Interim Scheme Assessment Report A27 Arundel Bypass – PCF Stage 2 Further Consultation 3.3.2.2 The A27 is the only east-west trunk road south of the M25.
