Final Version Proposed Quarry at Haddiscoe, Norfolk Environmental Impact Statement (Traffic & Highways) 13.0 TRAFFIC & HIGHWAYS Introduction 13. 1 This section of the Environmental Impact Statement assesses and considers the possible environmental impacts derived from the traffic and transport patterns associated with the proposals for the excavation of sand and gravel and associated processing facilities at Manor Farm, Haddiscoe. 13. 2 This section considers the site location, the proposed means of access and the level of vehicular traffic that is likely to be generated by the excavation proposal, and assesses the impact in terms of the current flows on the local highway network and the observed accident record for the area. 13. 3 The proposed means of vehicular access to the application site from the public highway, including the proposed upgrading, is described in detail, and the suitability of the design to accommodate the traffic associated with the development is examined. 13. 4 Scoping discussions were held with Norfolk County Council Highways (NCC) during May 2010 to discuss their requirements and identify the necessary components of the transport report. It was agreed that a Transport Assessment (TA) would be required to support the application as part of an Environmental Statement (ES). In terms of traffic assessment, NCC advised that suitable consideration of a study area comprising the A143 Church Hill/A143 Beccles Road/B1136 Loddon Road would be necessary. 13. 5 A full Transport Assessment has been prepared that is appended to this Environmental Impact Statement and concludes with a summary of the impact assessments carried out and an overview of the mitigation measures proposed, together with drawings detailing the proposed access works described within this chapter (refer to Part IV, V11). Site Location and highway network 13. 6 The application site, which comprises two parcels of land, is located immediately north and south of the B1136 Loddon Road, just west of the village of Haddiscoe, Norfolk. 13. 7 The northern parcel of land is bounded by the B1136 Loddon Road to the south, Crab Apple Lane to the west and Church Road to the north. Agricultural land forms the eastern boundary. The southern parcel is bounded to the north by the B1136 Loddon Road, with the remainder of its boundary flanked by farmland. The application site is currently grassland and agricultural use and has no established vehicular trip generation with the exception of the occasional agricultural vehicle. 13. 8 The B1136 Loddon Road is a single carriageway rural road. At the proposed access point into the southern parcel of land, the road is subject to the national speed limit of 60mph. Travelling east towards the village of Haddiscoe, the speed limit reduces to 30mph. October 2011 Created by SLR Consulting Limited - 157 - Final Version Proposed Quarry at Haddiscoe, Norfolk Environmental Impact Statement (Traffic & Highways) 13. 9 As a typical rural road, the carriageway is flanked by soft edging and although without formal street lighting benefits from centreline markings throughout with cats eyes to aid visibility for vehicles travelling in both directions. In keeping with its rural function, the road in close proximity to the application site does not have pedestrian footways and is bounded by intermittent hedgerows. 13. 10 With an average width of 5.5 metres, B1136 Loddon Road is predominantly of straight alignment from A143 Beccles Road up to its junction with Crab Apple Lane, after which the road becomes more winding with signage to advise of an approaching double bend. SLOW road markings are also provided to warn westbound drivers to lower their speeds. As a result, forward visibility on the road to the west of the proposed development site is reduced in places. 13. 11 Loddon Road, which becomes Yarmouth Road to the west, serves as a main east-west route for traffic travelling between Haddiscoe and Hales and links to the A146 Beccles Road to the west and the A143 Beccles Road to the east. There are a number of side roads and private access points joining the B1136 at regular intervals, all of different standard. The junctions are lightly trafficked; mainly serving small pockets of residential development and generally appear to operate to an acceptable level. 13. 12 To the east, B1136 Loddon Road forms a staggered priority junction with A143 Beccles Road and the opposing minor road, Rectory Road. The junction was subject to improvements to the Loddon Road approach in 2008 which have included local widening, the introduction of a new splitter island, new bi-directional road studs and new signage. 13. 13 The A143 Beccles Road serves as the main county distributor road between Great Yarmouth to the north and A146, Beccles and Bungay to the south. Beccles Road as it passes through the village is subject to a 30mph speed limit and the centreline is marked with no-overtaking markings through the series of shallow bends at this location. There is no street lighting, and footways are only provided on the opposing side of the carriageway to the Loddon Road arm, around the Rectory Road junction radii. The Proposed Development 13. 14 A full breakdown of the development to which this assessment relates is included within the description of the development, contained within Part I, Section 4.0. However, for the purposes of the Traffic and Transport Assessment, the development proposals may be summarised as follows. 13. 15 The development proposals comprise the extraction of around 1,450,000 tonnes of sand and gravel of which 1,311,000 will be extracted from the parcel lying north of Loddon Road, with the remaining 139,000 tonnes sourced from the southern parcel of land which will also form the Plant Site area. 13. 16 Upon commencement, extraction is expected to be undertaken at a rate of 75,000 tonnes per annum (tpa). Assuming that operations will begin sometime in 2012, extraction will take place over a 19 year period finishing in 2031 after which the restoration of the site is scheduled to take place over 12 months with the entire quarry restored during 2032. October 2011 Created by SLR Consulting Limited - 158 - Final Version Proposed Quarry at Haddiscoe, Norfolk Environmental Impact Statement (Traffic & Highways) 13. 17 Extraction of mineral will initially take place on the southern parcel of land, to the south of the B1136, which will be accompanied by the setting up of the Plant Site. This will include delivery of plant to the site, installation of the weighbridge and erection of the offices on the eastern part of the southern parcel. Operations will then transfer to the northern parcel of land where the extraction will continue in 10 planned phases. 13. 18 The development proposals include a new access junction onto the B1136 Loddon Road, which will serve the proposed plant area. This access would be a standard priority T- junction located at towards the north east corner of the site. As requested by Norfolk County Council and in accordance with guidance contained within TD 42/95 – ‘Geometric Design of Major / Minor Priority Junctions’, visibility splays measuring 4.5 metres x 215.0 metres will be provided. 13. 19 All mineral dug from the northern parcel will be transported to the Plant Site area on an underground conveyor which will be constructed beneath the B1136 Loddon Road. This will remove the need for any transfer of materials from the northern parcel to the southern parcel via the highway. 13. 20 After processing, mineral will be sold directly from the Plant Site Area. All material sold from the southern parcel will leave via an improved access point located onto Loddon Road. The average payload of vehicles leaving the site will be 20 tonnes. Once fully operational, the site is predicted to generate an average of approximately 32 HGV movements per day, all of which will be arriving and departing the Plant site to the south of the Loddon Road. 13. 21 To enable machinery and plant to access the northern parcel, the existing informal field access on Crab Apple Lane will be upgraded. No material will be transported via this access. Predicted Traffic Generation 13. 22 It is anticipated that the Quarry will operate on an annual output of some 75,000 tonnes of aggregate. On the basis of an average daily tonnage leaving the site of 300 tonnes, and with regards to the operation of another site operated nearby by the application, the projected traffic generation figures are as follows:- • 4 x 25t = 100t • 5 x 20t = 100t • 7 x 10t = 70t • 7 x 4.5t = 30t 13. 23 Thus there will be typically 23 aggregate vehicles per day leaving the site, of which 16 will be HGV and 7 MGV. 13. 24 It is anticipated that there will be some 30 movements of cars and light goods vehicles associated with staff, site operatives and deliveries working at or visiting the quarry site per average working day. October 2011 Created by SLR Consulting Limited - 159 - Final Version Proposed Quarry at Haddiscoe, Norfolk Environmental Impact Statement (Traffic & Highways) Baseline Conditions Review Current Transport Policy 13. 25 The site operation involves a relatively small workforce, and the site location is governed by the suitability for such a development. The suitability of the site for promoting non-car modes of travel is therefore strongly affected by the location of the site, the hours of working and the nature of the operation. However, it is still considered relevant to examine the policy background to determine the context within which the application will be assessed. National Policy 13. 26 The UK Government is committed to reducing congestion and promoting more environmentally-friendly and sustainable modes of transport through the 1998 Transport White Paper entitled ‘A New Deal for Transport: Better for Everyone’.
