The development is to be carried out by the Grwp Cynefin Housing Association. 1.2 The report will consider the impact of the proposed development on the highway network both during construction and operation and will assess the proposal in relation to planning policy and guidance. 2.0 SITE DETAILS 2.1 The proposed development site is a roughly rectangular plot of land 0.4Ha in area abutting the southwestern side of Station Road, Bethesda, 150m from the A5 Bangor Road. 2.2 A site location plan is included at Appendix A . 2.3 Bangor Road is part of the historic A5 trunk road between London and Holyhead and locally forms the high street of Bethesda. At its junction with Station Road it is straight and level with a carriageway 7.3m in width with footways on both sides. It is provided with street lighting and is subject to the normal urban speed limit of 30mph. There is a daytime waiting restriction on the Station Road side of the carriageway. 2.4 Station Road leaves Bangor Road perpendicularly and runs straight for 60m at which point it bifurcates at a shallow angle. It is bounded initially to the right (northwest) by houses and to the left by a small supermarket (Londis). 2.5 The left leg, Lon Sarnau provides access to houses, a large industrial unit and the rugby ground. 2.6 The right leg serves the Army Cadet Force premises and a new medical centre. After 70m it turns through 90degrees and forms the eastern boundary of and access to the proposed development site. It ends at a scaffolding company depot to the north of the site. 2.7 In all 18 residential properties gain access from Station Road and Lon Sarnau. 2.8 The first 60m section of Station Road has a 9.5 metre-wide level carriageway and a footway fronting the houses. It has street lighting and there is a 24-hour waiting restriction in force on the left (south-easterly) side for a distance of 50m from the A5 junction. 2.9 Beyond the junction with Lon Sarnau the carriageway is of variable width, generally about 8m. It is bounded by the above properties on the right and a stone wall to the left 1.3m in height. There is a footway around the frontage of the health centre and limited street lighting. 2.10 Lon Sarnau has a carriageway 4.5m in width with an arrow footway fronting the houses. 5084.06 / April 2017 1 RESIDENTIAL DEVELOPMENT, CLWB RYGBI, STATION ROAD, BETHESDA Transport Statement 2.0 SITE DETAILS (continued) 2.11 There is a broken edge marking across the Station Road/Lon Sarnau junction giving priority to Lon Sarnau. Because of the shallow intersection angle between the two roads the bellmouth is very wide, 25m at the give-way line. The boundary wall has been partially demolished at the junction, reducing in height from 1.3m to nothing over the last 18m. 2.12 The first section of Station Road and Lon Sarnau is a public highway (as far as the factory entrance). The adoption status of the section of Station Road from the junction to the proposed site is unclear. The above roads are subject to the normal urban 30mph speed restriction. 2.13 The Station Road/ Bangor Road junction is controlled by a double broken “give way” line. At this point the Bangor Road footway is 1.8m and 1.5m wide to the north and south respectively. To the right the adjacent building immediately abuts it. To the left there is a small yard to the front of the houses bounded by a wall 0.8m high. As a result of the above visibility of and from vehicles emerging from the minor road is limited. 2.14 The proposed site is level with a 105m frontage to Station Road. It takes the form of a single- storey building with surrounding parking/servicing areas. The building is used as a social club, the premises of the Clwb Rygbi Bethesda and the Bethesda AFC Bingo Club. 2.15 The Environment Act 1995 requires local authorities to review and assess air quality in their areas. In order to achieve their aims authorities are empowered to declare air quality management areas within which they can introduce measures to secure the required standards. 2.16 The site is not in an air quality management area. 3.0 ROAD SAFETY 3.1 The Council maintains records of reported collisions within the highway and enquiries have been made of the Authority with regard to the record in the vicinity of the site. The search covered Station Road; Lon Sarnau and Bangor Road within 50m of Station Road Road. The search period was 2010 to 2014, the latest five-year period for which data are available. 3.2 There were 3 collisions in the search area during the 5-year period all at the Bangor Road/Station Road junction. All three collisions took place in fine, dry conditions, one of them at night under street lighting and all were described as slight in severity. 3.3 Two of the collisions were similar in nature, being rear-end shunts of cars travelling northwards along Bangor Road. The first involved a car striking a parked vehicle, pushing into a second parked vehicle. The second involved a line of four cars colliding at the rear after the front vehicle had been temporarily held up. 5084.06 / April 2017 2 RESIDENTIAL DEVELOPMENT, CLWB RYGBI, STATION ROAD, BETHESDA Transport Statement 3.0 ROAD SAFETY (continued) 3.4 The third collision occurred when an elderly lady crossed Station Road into the path of a car turning right from Bangor Road. 3.5 Details of the collisions are at Appendix B . 4.0 TRAFFIC VOLUME AND SPEED 4.1 In order to assess the level of traffic on the surrounding highway network the following traffic counts were carried out. ••• Manual evening peak hour turning count at the A5/ Station Road junction on 3 February 2016. ••• An Automatic Traffic Count (ATC)for one week commencing 14 January 2016 in Station Road 15m from the A5 junction. ••• An ATC for one week commencing 14 January 2016 in A5 Bangor Road 25m north of Station Road. ••• An ATC for one week commencing 14 January 2016 in A5 Bangor Road 25m south of Station Road. 4.2 The results of the above ATCs are included at Figures 1-3 of Appendix C. The results of the turning count are shown in Figure 4. 4.3 Weekday 24-hour two-way flows at the A5 North, A5 south and Station Road sites were 7772, 7338 and 1207 vehicles respectively. Peak hour flows for the am (0800-0900) were 717, 689 and 96 vehicles. For the pm peak (1600-1700) the corresponding flows were 705, 674 and128 vehicles. 4.4 For the purpose of assessing the capacity of junctions, traffic flows are expressed in terms of passenger car units (PCU) that take account of the sizes of the different classes of vehicle. No classification of vehicles counted above is available and so the measured flows have been increased by a factor of 1.15 to allow for a proportion of HGVs of approximately 10%. 4.5 The peak hour flows have been apportioned in accordance with the results of the turning count to produce the base year turning flows used in the assessment of the capacity of the A5/ Station Road junction. 4.6 The base year flows are shown in Figures 5 and 6 of Appendix C . 4.7 The counts also measured traffic speeds. The 85%-ile speeds measured over the full 7-day period at the A5 north site were 27.9 mph and 28.6 mph south-east and north-westbound respectively. For the southern site the corresponding speeds were 27.9 and 28.7mph. 5084.06 / April 2017 3 RESIDENTIAL DEVELOPMENT, CLWB RYGBI, STATION ROAD, BETHESDA Transport Statement 4.0 TRAFFIC VOLUME AND SPEED (continued) 4.8 For the purpose of assessing junction visibility splay requirements wet weather speeds are used and dry weather survey figures are adjusted accordingly. During the January survey period the weather was predominantly wet and so no adjustment of the measured speeds has been required. 5.0 PUBLIC TRANSPORT 5.1 The area surrounding the site is served by public transport in the form of the 6/6A; 66/66A/67/67A bus services.
