Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 1.0 INTRODUCTION 1.1 David Tucker Associates (DTA) has been commissioned by A C Lloyds Homes Ltd to review the transport implications of the proposed development of 200 dwellings at land south of Chesterton Gardens, Sydenham, Leamington Spa. The site location is shown on Figure 1 and the indicative site masterplan is attached at Appendix A. 1.2 This Transport Assessment (TA) has been prepared in accordance with the National Planning Policy Framework (NPPF) 2019 and National Planning Practice Guidance issued in March 2014. 1.3 This report considers the transport and highways implications associated with the proposals and is structured as follows: • Chapter 2: Policy Context; • Chapter 3: Existing Conditions; • Chapter 4: Access and Movement Strategy; • Chapter 5: Development Proposals; • Chapter 6: Traffic Generation and Distribution; • Chapter 7: Traffic Impact Assessment; and • Chapter 8: Conclusions. 1.4 The scope of this TA, specifically including traffic generation, distribution and junction impacts have been discussed and agreed with Warwickshire County Council as Local Highway Authority (LHA). 1.5 This TA has been updated following refusal of planning application W/20/0617. That application is being appealed (Ref APP/T3725/W/21/3270663). Whilst WCC did not raise any objections subject to the provision of suitable contributions and works (see Appendix B), the Planning Authority refused the application with reason for refusal 1 stating: RFR1: The provision of a single vehicular access to the site via an existing residential area would result in a substandard form of development that would not provide an attractive or safe route for vehicles into the site or within that wider area due to the circuitous nature of the access through an existing residential cul-de-sac and the resulting traffic volumes. The provision of an additional 200 dwellings off a singular point of access to this development is therefore considered to be DN/20376-03 Transport Assessment 1 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment detrimental to highway safety. The proposal is therefore considered contrary to Policy TR1 of Local Plan. 1.6 This report has been updated (previous TA date July 2019) to primarily: • Reflect any changes in recorded injury accidents in the study area • Reflect changes to the public transport services in light of COVID. • Include a safety audit of the proposed access arrangements to respond to the concern raised in the RfR1 regarding the access into the site not being attractive or safe. • Introduce a concept traffic calming scheme for the local road network in response to a request from WCC for a such a scheme to be funded by the developer. • Provide clarification on distances to facilities/ amenities and bus stops. 1.7 All impact assessment work is consistent with the previous transport assessment (20376- 01a) due to the assessment year being 2021. 1.8 This TA considers the potential transport and highways impacts of the proposals including the impact of development generated traffic on the capacity and safety of the surrounding road network. 1.9 Access to the site is proposed to be via Brimstone End within the recently completed Chesterton Gardens development to the south of St Fremund Way. It will therefore, be served by the existing road network. The pre-application technical note (see Appendix C) which has thoroughly analysed these local road networks has made the following comments: “…it has been demonstrated that Chesterton Drive currently operates within its theoretical capacity and will continue to do so with the inclusion of a further 200 dwellings”. 1.10 This TA considers the potential transport and highways impacts of the proposals including the impact of development generated traffic on the capacity and safety of the surrounding road network. It is concluded that proposed development would have no material residual adverse impact on the safe operation of the local highway network. DN/20376-03 Transport Assessment 2 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 2.0 POLICY CONTEXT 2.1 National Policy National Planning Policy Framework (2019) 2.1.1 In February 2019, the Government published a revised National Planning Policy Framework (NPPF). This report should therefore be read in the context of the new NPPF. 2.1.2 Paragraph 109 of the NPPF is clear that: "Development should only be prevented or refused on highways grounds if there would be an unacceptable impact on highway safety, or the residual cumulative impacts on the road network would be severe". 2.1.3 Within this context, the NPPF identifies in Paragraph 110 that applications for development should: "a) give priority first to pedestrian and cycle movements, both within the scheme and with neighbouring areas; and second – so far as possible – to facilitating access to high quality public transport, with layouts that maximise the catchment area for bus or other public transport services, and appropriate facilities that encourage public transport use; b) address the needs of people with disabilities and reduced mobility in relation to all modes of transport; c) create places that are safe, secure and attractive – which minimise the scope for conflicts between pedestrians, cyclists and vehicles, avoid unnecessary street clutter, and respond to local character and design standards; d) allow for the efficient delivery of goods, and access by service and emergency vehicles; and e) be designed to enable charging of plug-in and other ultra-low emission vehicles in safe, accessible and convenient locations." DN/20376-03 Transport Assessment 3 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 2.1.4 Paragraph 111 of the NPPF goes on to state that: "All developments that will generate significant amounts of movement should be required to provide a travel plan, and the application should be supported by a transport statement or transport assessment so that the likely impacts of the proposal can be assessed". 2.1.5 In reinforcing the principle of supporting sustainable development, paragraph 10 stipulates that at the heart of the Framework is "...a presumption in favour of sustainable development". National P lanning P ractice Guidance (M arch 2014) 2.1.6 The Department for Communities and Local Government (CLG) published the Planning Practice Guidance (PPG), which reinforces the guidance contained in the NPPF. 2.1.7 In particular in para 32 the PPG states: “Local planning authorities must make a judgement as to whether a development proposal would generate significant amounts of movement on a case by case basis (i.e. significance may be a lower threshold where road capacity is already stretched or a higher threshold for a development in an area of high public transport accessibility). In determining whether a Transport Assessment or Statement will be needed for a proposed development local planning authority should take into account the following considerations: • The Transport Assessment and Statement policies (if any) of the Local Plan; • The scale of the proposed development and its potential for additional trip generation (smaller applications with limited impacts may not need a Transport Assessment or Statement); • Existing intensity of transport use and the availability of public transport; • Proximity to nearby environmental designations or sensitive areas; • Impact on other priorities/ strategies (such as promoting walking and cycling); • The cumulative impacts of multiple developments within a particular area; and • Whether there are particular types of impacts around which to focus the Transport Assessment or Statement (e.g. assessing traffic generated at peak times). DN/20376-03 Transport Assessment 4 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 2.1.8 The document advocates early consultation with key decision makers at an early stage through pre-application discussions to determine the scope of the technical work required to underpin the associated assessments and travel plans. The key issues it suggests that should be considered are: • The planning context of the development proposal; • Appropriate study parameters (i.e. area, scope and duration of study); • Assessment of public transport capacity, walking/ cycling capacity and road network capacity; • Road trip generation and trip distribution methodologies and/ or assumptions about the development proposal; • Measures to promote sustainable travel; • Safety implications of development; and • Mitigation measures – including scope and implementation strategy. 2.1.9 It acknowledges that the scope and level of detail in reports will vary from site to site, but suggests the following should be considered when settling the scope of the proposed assessment: • information about the proposed development, site layout, (particularly proposed transport access and layout across all modes of transport); • information about neighbouring uses, amenity and character, existing functional classification of the nearby road network; • data about existing public transport provision, including provision/ frequency of services and proposed public transport changes; • a qualitative and quantitative description of the travel characteristics of the proposed development, including movements across all modes of transport that would result from the development and in the vicinity of the site; • an assessment of trips from all directly relevant committed development in the area (i.e. development that there is a reasonable degree of certainty will proceed within the next three years); • data about current traffic flows on links and at junctions (including by different modes of transport and the volume and type of vehicles) within the study area and identification of critical links and junctions on the highways network; DN/20376-03 Transport Assessment 5 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment • an analysis of the injury accident records on the public highway in the vicinity of the site access for the most recent three-year period, or five-year period if the proposed site has been identified as within a high accident area; • an assessment of the likely associated environmental impacts of transport related to the development, particularly in relation to proximity to environmentally sensitive areas (such as air quality management areas or noise sensitive areas); • measures to improve the accessibility of the location (such as provision/ enhancement of nearby footpath and cycle path linkages) where these are necessary to make the development acceptable in planning terms; • a description of parking facilities in the area and the parking strategy of the development; • ways of encouraging environmental sustainability by reducing the need to travel; and • measures to mitigate the residual impacts of development (such as improvements to the public transport network, introducing walking and cycling facilities, physical improvements to existing roads. In general, assessments should be based on normal traffic flow and usage conditions (e.g. non- school holiday periods, typical weather conditions) but it may be necessary to consider the implications for any regular peak traffic and usage periods (such as rush hours). Projections should use local traffic forecasts such as TEMPRO drawing where necessary on National Road Traffic Forecasts for traffic data. The timeframe that the assessment covers should be agreed with the local planning authority in consultation with the relevant transport network operators and service providers. However, in circumstances where there will be an impact on a national transport network, this period will be set out in the relevant Government policy.

Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 2.2 Local Planning Policy W arw ick District Local Plan (2011-2029) 2.2.1 This document sets out the council’s policies and proposals supporting development of the district through to 2029. The purpose of the plan is to establish the long-term spatial vision of the district and how this will be delivered through a sustainable strategy. 2.2.2 This development proposes a total quantum of 200 residential units within a first phase, and will be a mix of affordable and private housing. 2.2.3 DS11 (Allocated Housing Sites) - The application site forms part of a wider allocation (H03: East of Whitnash/south of Sydenham) identified for a development of 500 dwellings under Policy DS11: Allocated Housing Sites. 2.2.4 The following are the relevant transport policies contained in the plan. TR1 (Access and Choice) Development will only be permitted which provides safe, suitable and attractive access routes for pedestrians, cyclists, public transport users, delivery vehicles and other users of motor vehicles, as appropriate. Development proposals will be expected to demonstrate that they: a) are not detrimental to highway safety; b) are designed to provide suitable access and circulation for a range of transport modes including pedestrians, cyclists and public transport services; c) create safe and secure layouts for motorised vehicles, cyclists, pedestrians and public transport and integrate the access routes into the overall development; d) incorporate facilities for charging plug-in and other ultra-low emission vehicles where the development proposals include provision for off street parking and is for one or more dwelling, and; e) have taken account of the needs of people with disabilities by all modes of transport” DN/20376-03 Transport Assessment 7 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment TR2 (Traffic Generation) TR2 Traffic Generation All large-scale developments which result in the generation of significant traffic movements, should be supported by a Transport Assessment and where necessary a Travel Plan, to demonstrate practical and effective measures to be taken to avoid the adverse impacts of traffic. Any development that results in significant negative impacts on health and wellbeing of people in the area as a result of pollution, noise or vibration caused by traffic generation will not be permitted unless effective mitigation can be achieved. Any development that results in significant negative impacts on air quality within identified Air Quality Management Areas or on the health and wellbeing of people in the area as a result of pollution should be supported an air quality assessment and, where necessary, a mitigation plan to demonstrate practical and effective measures to be taken to avoid the adverse impacts. A Transport Statement will be required for development that has relatively small transport implications in line with the Guidance on Transport Assessments. All measures required in the Policy should take full account of the cumulative impact of all development proposed in this Plan (and any other known developments) on traffic generation and air quality. TR3 (Parking) Development will only be permitted that makes provision for parking which: - a) does not encourage unnecessary car use; b) has regard to the location and accessibility of the site by means other than the private car; c) does not result in on-street car parking detrimental to highway safety; d) takes account of the parking needs of disabled car users, motorcyclists and cyclists; and e) takes account of the requirements of commercial vehicles. Development will be expected to comply with the parking standards set out in the most recent Parking Supplementary Planning Document. DN/20376-03 Transport Assessment 8 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment DM1 (Infrastructure Contributions) DM1 Infrastructure Contributions Development will be expected to provide, or contribute towards provision of: a) Measures to directly mitigate its impact and make it acceptable in planning terms; and b) Physical, social and green infrastructure to support the needs associated with the development. Infrastructure and mitigation measures will be provided in a timely manner to support the objectives of the Plan. The Council will, where appropriate, seek to secure site-specific infrastructure investments and/or contributions as well as off-site contributions and/or investments. The nature and scale of these will be related to the form of development and its potential impact on the site and surrounding area. The cumulative impact of developments will also be taken into account. Developer contributions in the form of Planning Obligations and/or Community Infrastructure Levy (CIL) will contribute towards strategic infrastructure required to support the overall development in the Plan. The Council will work in partnership with infrastructure providers and other delivery agencies in updating the Infrastructure Delivery Plan to ensure an up to date evidence base regarding infrastructure requirements and costs is maintained. Warwickshire District Council: Residential Design Guide W arw ick District Council: R esidential Design Guide 2.2.5 The guide sets out what the Council expect in terms of good design and includes advice on layout, density, character, local architectural styles, materials, access and parking, landscaping and open space. W arw ickshire’s Local Transport P lan 2.2.6 Warwickshire’s Local Transport Plan 3 presents the county’s approach to transport and the vision, goals and challenges that the county wishes to achieve and the reasons for it. The document sets out its purpose in the following passages: DN/20376-03 Transport Assessment 9 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment • To promote greater equality of opportunity for all citizens in order to promote a fairer, more inclusive society; • To seek reliable and efficient transport networks which will help promote full employment and a strong, sustainable local and sub-regional economy; • To reduce the impact of transport on people and the [built and natural] environment and improve the journey experience of transport users; • To improve the safety, security and health of people by reducing the risk of death, injury or illness arising from transport, and by promoting travel modes that are beneficial to health; • To encourage integration of transport, both in terms of policy planning and the physical interchange of modes; • To reduce transport’s emissions of carbon dioxide and other greenhouse gases, and address the need to adapt to climate change. 2.2.7 The policies relevant to Development Control are primarily set out in the land use and transportation strategies. Policies relevant to this development are: Policy LUT5: Transport assessments The County Council will require Transport Assessments/Statements to be submitted to support planning applications where it is deemed appropriate. The information should follow the general guidance on Transport Assessments as published by the Department for Transport. Where significant development is proposed, the County Council will require the use of Micro-Simulation modelling techniques to support the Transport Assessment process. The County Council will also work with applicants to scope the individual requirements for the sites/areas under assessment. Policy LUT8: Road safety audits The County Council will require an appropriately staged Safety Audit to accompany any planning application that requires certain works within the highway to be carried out, for example new junctions, ghost island junctions and significant alterations to existing junctions. It is recommended that the applicant should contact the County Council for advice and guidance on these issues at the earliest opportunity. DN/20376-03 Transport Assessment 10 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 3.0 EXISTING CONDITIONS 3.1 Site Location 3.1.1 The proposed development is located south of the Bridleway known as Greenfield Road. The site is currently a field used for agricultural purposes. It is bound to the east by open fields and to the west by the railway line which runs into Leamington Spa from Banbury. At the northern boundary of the site previous phases of residential development have been completed and fully occupied. The location of the proposed development is shown on Figure 1. 3.2 Highway Network 3.2.1 The local road network in relation to the proposed development is also shown on Figure 1. 3.2.2 Greenfield Road Bridleway directly borders the northern boundary of the site, it is a narrow lane of approximately 2.5m wide with no lighting and a loose gravel surface. Running immediately north and parallel with this is the new internal road network of Chalkhill Place within Chesterton Gardens. The network comprises carriageways including Chalkhill Place, Brimstone End, Emperor Boulevard and St Fremund Way. These carriageways are well lit, are between approximately 6.5 and 7.0m wide and are subject to a 20mph speed limit. These interconnected carriageways are linked together via priority T-junction facilities. 3.2.3 The local highway network described above can be accessed via Chesterton Drive. Chesterton Drive runs from approximately 1km north west of the site’s northern boundary, where Prospect Road, Sydenham Drive and Chesterton Drive meet at a 4-arm roundabout. From the 4-arm roundabout Chesterton Drive stems east and then south for approximately 500m where it runs into St Fremund Way. Chesterton Drive is subject to a 30mph speed limit. 3.2.4 Approximately 1km north west of the site a 4-arm roundabout provides access to central Leamington and Warwick. To the west Prospect Road runs into Tachbrook Road which provides links to the Queensway and A452. The A452 can be followed south where it links with the M40 running between Oxford (south) and Birmingham (north). To the north of the Sydenham Drive links with carriageways running north out of Leamington Spa and further to Kenilworth and Coventry. DN/20376-03 Transport Assessment 11 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 3.3 Existing Traffic Flows 3.3.1 In order to establish existing flows in the vicinity of the site, an automated traffic count (ATC) was undertaken on Chesterton Drive located approximately 1km north of the site. The ATC was undertaken between the 18th May 2018 and the 24th May 2018. The full results are attached at Appendix D. Table 1 provides summaries of the ATC results, including both volumetric and speed data. Table 1 - Summary of ATC traffic volume and speed Volumetric Speed 5-day 7-day AM PM 85th %ile Average Average Average Peak Peak (mph) (mph) Northbound 1771 1702 223 215 29.5 24.6 Southbound 1784 1712 58 111 29 23.9 3.3.2 The average peak two-way traffic flows for the weekday were recorded between 08:00- 09:00 at 281 (223 + 58) vehicles and 17:00-18:00 at 326 (215 + 111) vehicles. This demonstrates that the highest traffic flows still occur during the traditional AM and PM peak periods. 3.3.3 Table 1 in TA79/99 categorises roads into types. Those relevant to Chesterton Drive would be the classifications of either UAP3 or UAP4. They are described as: UAP3 – Variable standard road carrying mixed traffic with frontage access, side roads, bus stops and at-grade pedestrian crossings. UAP4 – Busy high street carrying predominantly local traffic with frontage activity included loading and unloading. 3.3.4 Table 2 of TA79/99 presents the one-way hourly capacity for the classification of roads. The two widths in the table similar to Chesterton Drive are 6.1m and 6.75m. 3.3.5 The results of classifying Chesterton Drive as a UAP4 road with a width of 6.1m suggests the road could cater for a busiest one-way flow of 750 vehicles and a two-way capacity of 1250 vehicles (based on the stated 60/40 split). 3.3.6 The volumetric results of the ATC survey demonstrate that the busiest two-way recorded flows above is 326 vehicles, which is significantly lower than the maximum capacity of 1250. DN/20376-03 Transport Assessment 12 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 3.3.7 The speed results of the ATC survey demonstrate that the average speed both southbound and northbound are similar at 23.9 and 24.6mph respectively. 3.3.8 The 85th percentile speed was recorded at 29.0mph southbound and 29.5mph northbound. 3.3.9 Furthermore, according to the ATC survey regarding the ‘class’ of traffic over a 12-hour average both southbound and northbound yielded comparable results with 92% of recorded traffic attributable to cars and less significant percentages to LGVs, HGVs and Motorcycles. 3.3.10 A classified turning count survey was also undertaken at the junction of Chesterton Drive and St Fremund Way. This CTC was in operation on Tuesday 22nd May 2018 during the period of the ATC. The camera which carried out the CTC survey was located to the east of the junction; the view is shown on Image 1 below. Image 1 - Camera View of Chesterton Drive Junction - CTC Undertaken Here 3.3.11 The data obtained from the CTC analysis have been compiled and used in order to generate existing condition Traffic Flow Turning diagrams for the Chesterton Drive/ St Fremund Way junction. These diagrams are shown in Image 2 and Image 3 below. DN/20376-03 Transport Assessment 13 15th March 2021

The PIC output plan and full reports are attached at Appendix E. DN/20376-03 Transport Assessment 14 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 3.4.2 The study area includes; • The junction of Sydenham Drive/ Prospect Road/ Chesterton Drive, along Chesterton Drive, Ft Fremund Way through to Emperor Boulevard; • The section of Church Lane between Whitnash Road and the railway line has also been included; and • The Bridleway along the northern boundary of the site. 3.4.3 There have been 6 PICs in the last 5-years within the analysed area. These are summarised below: • Slight - Chesterton Drive/ Packwood Close Junction – Car drove into the rear of a parked car. • Slight - Chesterton Drive/ Sydenham Drive Junction – Cyclist failed to indicate resulting in a collision with a turning vehicle. • Slight - Chesterton Drive/ Asda Junction – A vehicle turned across the path of another when turning right into the superstore car park. • Slight – St Fremund Way/ Otters Rest Junction – A cyclist left the footway and collided with a turning vehicle. • Slight – Campion School Roundabout – Two cyclists collided. • Serious – Chesterton Drive/ Moncrieff Drive Junction – Car hit rear of a turning cyclist. 3.4.4 After review of this PIC data it is clear that all of the incidents can be attributed to human behaviour errors. There are no significant existing road safety issues and the traffic generated by the proposed development would therefore not compromise road safety.

Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 4.0 ACCESS AND MOVEMENT STRATEGY 4.1 Introduction 4.1.1 The overall Access and Movement Strategy for the proposed development is based on the principle of utilising newly developed road networks which have been established to serve a completed residential development on land to the South of St Fremund Way and which are situated adjacent to the proposed site location. 4.2 Pedestrian and Cycle Access 4.2.1 The existing road network in the vicinity of the proposed development site which comprises Chalkhill Place, Brimstone End, Emperor Boulevard and St Fremund Way, has been newly developed to serve phase 1 of the residential development masterplan in Sydenham. This highway network accommodates pedestrians and cyclists with consistent on-street lighting and footways which run along both sides of all carriageways. Footways are a minimum of 2.0m wide and dropped tactile paving provided at appropriate crossing points. For example, that shown in Image 4 below where Mill Pond Meadows meets St Fremund Way at a priority T-junction. Image 4 - Priority T-junction at Mill Pond Meadows and St Fremund Way DN/20376-03 Transport Assessment 16 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 4.2.2 Along Chesterton Drive the footways remain consistently at a minimum of 2.0m wide however, in some places the footway is limited to one side of the road and this is the same for street lighting. There is one pelican crossing and some dropped tactile paving along Chesterton Drive which will enable safer crossing for pedestrians. 4.2.3 A dedicated cycleway runs along the western boundary of Sydenham Drive for approximately 800m before reaching the Chesterton Drive/ Sydenham Drive/ Prospect Road 4-arm roundabout junction. At this junction the cycleway bears east and continues along Chesterton Drives northern boundary for approximately 50m before merging with the carriageway. 4.2.4 National cycle route 41 runs approximately 2km north of the site, accessed off Radford Road and providing a primarily traffic free route east into Leamington Spa centre and west through Long Itchington. Leamington Spa is within the Cycleways area, Cycleways is a volunteer group who work to campaign for better cycling provision within Warwickshire. 4.2.5 With regard to the development site, there would be extensive provision to facilitate foot and cycle movements throughout the site. This will include provision of the following where appropriate in line with the DfT’s MfS and MfS2: • A good level of street and path lighting; • Warning signs prior to junctions; • On-site roads will be designed to 20mph; • Tactile and coloured surfacing; • Safety kerbing; • Reduced junction mouth widths to promote slower vehicle speed where appropriate; and • Signage to direct pedestrians and cyclists to key facilities and places of interest, including distances. 4.2.6 A mix of cycle parking facilities will be provided at the development to comply with local standards and will be designed and tailored to the likely needs of future occupants. Cycle parking will be provided within the confines of a dwelling/ garage, or alternatively provided in secure, well lit, covered cycle storage facilities.

Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 4.3 Bus Service Provision 4.3.1 The nearest bus services to the site are to the north on St Fremund Way, which is approximately 400m from the centre of the site’s northern boundary (700m from the south eastern corner of the site following the proposed and existing footways). The nearest stops to the west are on Whitnash Road approximately 500m away (730m from the site’s south-eastern corner). A summary of the bus services in the area are shown in Table 2 below. Table 2 - Summary of Bus Services Frequency Service Stop Route Mon-Fri Sat Sun Withy Sydenham - Every 30 mins Every 30 mins Every 30 mins 67 Bank Leamington (06:37 – 18:57) (06:57 – 18:57) (08:45 – 20:12) Church Whitnash – Leamington Every 20 mins Every 20 mins Every 30 mins 1 Lane - Warwick (06:00 – 22:48) (06:50 – 22:48) (09:15 – 18:15) 4.3.2 St Fremund Way provides access to the number 67 service operated by Stagecoach, which offers a 30 minute frequent service to Leamington Spa town centre, Monday to Saturday with a journey time of circa 17 minutes. The service frequency has been slightly reduced due to the current COVID pandemic from 20 min service. Furthermore, due to closures to The Parade in Leamington the service now takes an alternative route to the north of the Town. 4.3.3 Whitnash Road provides access to the No.1 service which is also operated by Stagecoach. The 1 generally offers a 20 minute frequent service to Leamington Spa and Warwick, Monday to Friday. The Saturday service is also every 20 minutes which increases to every 30 minutes on Sundays. Again the frequency of the service prior to the COVID pandemic was every 10 mins. 4.3.4 All services offer provision during early morning and late evening periods, providing a suitable alternative mode of travel to that of the private car. 4.3.5 Whist it is proposed the site will provide for bus stops etc through the future reserved matters applications, it is not intended to extend the service into the site for this phase. DN/20376-03 Transport Assessment 18 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 4.3.6 The stops and associated infrastructure would “future proof” the site when the land to the south in the wider allocation comes forward for development. Dwellings in those phases would likely be beyond what would be considered to be a reasonable walking distance to those existing bus stops on St Fremund Way and Whitnash Road. 4.4 Rail Service Provision 4.4.1 The nearest train station to the proposed development is Leamington Spa Station which is located approximately 2.5km north west. This translates into an approximate walking/ cycling time of 31/ 8 minutes. 4.4.2 The station is operated by Chiltern railways and provides secure bicycle parking stands with space for 198 bikes, and a car park with 706 spaces and an additional 8 accessible spaces provided. 4.4.3 Train services include half-hourly connections to and from Birmingham New Street/ Moor Street, London Marylebone and other less frequent services for example the hourly service to and from Manchester Piccadilly. 4.5 Local Facilities 4.5.1 This section of the TA considers access to the following services: • Education; • Food retail; • Doctor’s surgery; and • Employment. 4.5.2 The majority of trips that will be made by foot or cycle from the proposed development will be for the purpose of short shopping trips, access to leisure facilities, school journeys, and trips to bus stops as part of linked trips to other destinations. A Local Facilities Plan is shown at Figure 1. DN/20376-03 Transport Assessment 19 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 4.5.3 It is generally considered that for distances under 2km, walking offers the greatest potential to replace short car trips. This is confirmed by Manual for Streets (DfT 2007) which confirms that: “Walkable neighbourhoods are typically characterised by having a range of facilities within 10 minutes (up to approximately 800m) walking distance of residential areas which residents may access comfortably on foot. However, this is not defined as an upper limit and PPG13 states that walking offers the greatest potential to replace short car trips, particularly those under 2km”. Furthermore, for distances under 5km, cycling has the potential to substitute for short car trips. 4.5.4 Accessibility by foot to local amenities was determined by measuring the distances from the site access to the local amenities. Distances of 400m, 800m and 1200m for walking were measured along the most direct routes between the site and the facilities/ amenities. Distances of 1km, 2.5km and 5.0km for cycling were measured along the most direct routes between the site and the facilities/ amenities. Image 5 and Image 6 show the resulting isochrones.

Whitnash Primary School is a similar distance to the west via Church Lane. 4.5.6 St Anthony’s Catholic Primary School is located slightly further north at approximately 2.2km, this translates into walking/ cycling times of 26/ 8minutes respectively. 4.5.7 Campion Secondary School is located approximately 700-900m north of the site. Pedestrians can utilise the footway that runs parallel with the railway line northbound, this journey translates into an approximate walking/ cycling time of 10/ 2 minutes respectively. 4.5.8 The distance of all of the schools near the site are within the distance shown by the 2014 National Travel Survey, where 80% of pupils are more likely to walk to school than be driven. This increases to 90% for secondary school trips. DN/20376-03 Transport Assessment 21 15th March 2021
Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment Food Retail 4.5.9 There is an Asda Leamington Spa Superstore located off Chesterton Drive approximately 1km north of the site. This translates into a walking/ cycling time of 13/ 4 minutes. 4.5.10 Within Leamington Spa town centre there are a number of other supermarkets including Co-op and Morrisons. Additionally, there is a parade of local shops located on Home Farm Crescent in Whitnash 800m west of the site and easily accessed by pedestrians and cyclists. Doctor’s Surgery 4.5.11 In terms of access to health provisions, Croft Medical Centre is located 1.4km north of the site accessed via St Fremund Way and Chesterton Drive. The centre is open Monday- Friday between 7:00am-7:30pm providing regular GP appointments and other more specialist treatments. Employment 4.5.12 With regards to employment, a review of 2011 Census data for the Middle Super Output Area (MSOA) of Warwick 015 within which the proposed development is located shows that approximately 2% of residents live and work within the same MSOA. The majority of residents within the Warwick 015 MSOA travel to another MSOA location for work. Approximately 58% of residents work in any Warwick MSOA, 9% in Stratford-upon-Avon and a further 10% work in Coventry. 4.5.13 A summary of the Census 2011 MSOA destination of work data is shown in Table 3 below.

Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 5.0 DEVELOPMENT PROPOSALS 5.1 The current development proposals are for up to 200 residential properties. 5.2 The proposed vehicle access to the site will be from the existing highway network servicing a previous phase of the Chesterton residential development immediately north of the proposed site boundary. The access point to the site will be from Brimstone End where it meets Greenfield Road and through an existing gateway, this access will need to be widened and earthwork levelling works to be undertaken. This access plan can be found at Drawing 20376-01e. 5.3 The access proposes a formalised give way arrangement to assist with preventing vehicles turning on and off the existing bridleway. 5.4 Through discussions with regular users of the bridleway for accessing land to the east two, passing bays have been included either side of the access road. 5.5 Visibility splays with an ‘x’ distance of 2.4m back from the give way line to ‘y’ distances of 25m along the bridleway will be provided. 5.6 An independent stage 1 road safety audit has been undertaken on the proposed bridleway crossing arrangement. The audit highlighted concerns regarding the priority arrangement and interaction between users of the bridleway and the site access. The scheme has been progressed to include the majority of recommendations made. A safety audit response report has been drafted which sets out how the scheme has been progressed to respond to the issues and recommendations which is attached at Appendix G. 5.7 The bridleway also serves to provide an accepted emergency access via Church Lane to the previous phase of development. This arrangement is to be continued for this phase via an emergency access link to the northwest corner of the development as shown indicatively on the masterplan. 5.8 The bridleway provides pedestrian and cycle access to the west via Church Lane and into the south of Campion School via existing connections.

When compared with trip rates derived from ATC and address data, the trip rates from TRICS were higher in the AM peak and over a full day however, were lower in the PM peak. Table 8 - TRICS Derived Trip Rates IN OUT TOTAL AM 0.170 0.551 0.721 PM 0.372 0.187 0.558 DAILY 2.674 2.762 5.437 6.1.5 Due to evening peak hour being the busiest and that the local data represents the area more accurately, the ATC derived trip rates have been agreed with WCC for testing. However, to ensure an overly robust assessment the higher TRICS rates have been used in the assessment of the development. Therefore, using the trip rates in Table 8, a forecast traffic generation for 200 dwellings has been calculated. The results are summarised in Table 9 below.

Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 6.1.6 The forecast two-way link flow for Chesterton Drive inclusive of the proposed development during the AM Peak is 426 (281 + 145) and during the PM Peak is 439 (326 + 113). As stated in section 3.3.5; classification of Chesterton Drive as a category UAP4 road with a width of 6.1m suggests that the road is able to cater for maximum flows of 750 one way and 1250 two-way vehicle movements based upon a one-way, two-way 60/40 split. Therefore, it can be summarised that Chesterton Drive will operate at approximately one third of its maximum 1250 capacity two-way flow during both the AM and PM Peak inclusive of the proposed development. 6.2 Traffic Distribution 6.2.1 The forecast traffic generation has been distributed using the Census Journey to Work data (2011) for the Warwick 015 Middle Super Output Area (MSOA), presented in section 4.5.12 to 4.5.16, within which the proposed development is located. A breakdown of trip location distribution from this area to employment destinations is summarised in Table 4. 6.2.2 The Census 2011 data demonstrates that the three key employment areas for residents at the site are Warwick MSOAs, Stratford-Upon-Avon MSOAs and Coventry comprising 77% of the total journey locations. 6.2.3 Using the most direct route to employment destinations obtained from online routing software a development traffic distribution diagram has been generated, this is attached at Appendix F. The primary initial distributions from the proposed site are 58% west along Prospect Road, 37% north along Sydenham Drive. From here various routes are taken by traffic according to location of employment. 6.2.4 The distribution assumptions have been used in the wider S-Paramics modelling presented to WCC in the pre-application technical note(s).

Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 6.3 Background Traffic Growth 6.3.1 In accordance with DfT guidance, the base traffic flows have been factored up to a future year of 2021 when the development should be completed. Local TEMPRO growth factors have been used for the Middle Super Output Area (MSOA) Warwick 015 in which the proposed development site is located. The resulting factors (based upon an average calculation) are shown below in Table 10. Table 10 - TEMPRO Growth Factors for 2021 TEMPRO Growth Factors 2021 Area Definition Date Range Road Classification AM PM Warwickshire 015 2016-2021 1.0808 1.0798 Urban, Principle (Leamington Spa) 2018-2021 1.0462 1.0456 6.3.2 This shows that background traffic running in proximity to the proposed development site is predicted to increase 8% in the AM Peak and 8% in the PM Peak between 2016-2021. 6.3.3 The TEMPRO factors include all known committed development not captured by the recently collected traffic count data.

Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment Table 12 – Sydenham Drive/ Chesterton Drive/ Prospect Road Roundabout Junction 7.6 The results of the assessment show that the roundabout will continue to operate in both peak hours with minimal queueing and delay. 7.7 The impacts of the development on the wider highway network have been tested in WCC’s S-Paramics model which shows little impact on the local and wider network. This was contained in an exercise that tested the whole allocation to determine the need for any potential mitigation and what scale of development would trigger that mitigation. The results of this work demonstrated that prior to the delivery of 450 dwellings within the allocation no direct mitigation was required. Pre-application Technical Note 2 is attached at Appendix K. 7.8 Notwithstanding the limited impact of the development it is likely S106 contributions will be sought to wider highway schemes identified through the plan making process in support of the housing and employment allocations.

Land South of Chesterton Gardens, Sydenham, Leamington Spa Transport Assessment 8.0 CONCLUSION 8.1 This TA has reviewed the highways and transport implications of providing 200 residential dwellings on land south of Chesterton Gardens, Sydenham, Leamington Spa. 8.2 This first phase of development is south of the Bridleway known as Greenfield Road and will be within acceptable walking distances of facilities and bus stops. 8.3 Using the classifications set out in TA79/99 of the Design Manual for Roads and Bridges, it has been demonstrated that Chesterton Drive currently operates within its theoretical capacity and will continue to do so with the inclusion of a further 200 dwellings. 8.4 The junctions of Chesterton Drive/ St Fremund Way and Chesterton Drive/ Sydenham Drive have been assessed using industry standard software and is also shown to currently operate within capacity and will continue to with the inclusion of the additional housing. 8.5 It can be concluded that the first phase of development can be accommodated within the existing highway infrastructure resulting in no material impacts on either safety or capacity. 8.6 Therefore, subject to reasonable and proportional S106 contributions towards cumulative offsite impacts, there are no reasons why a first phase of development of circa 200 dwellings would not be acceptable on the grounds of highways and transport.
