The site is located in the London Borough (LB) of Bromley, with the council being both the planning authority and highway authority. 1.2 Marjorie McClure SEN School is an existing 100 pupil all-through school located on Hawkhood Lane in Chislehurst. The Department for Education are proposing to relocate the school to a site located adjacent to the existing Edgebury Primary School to the north of Edgebury which has been allocated in the Bromley Local Plan for educational uses. To the east and north is Slades Drive whilst to the west is Brownspring Drive. The site is located 900m to the north of Chislehurst town centre. The site location is shown within Figure 1, whilst an illustrative site layout is provided within Appendix A. 1.3 The school development will consist of a 100 space car park, drop-off area, a vehicular access off Slades Drive and a new pedestrian connection with Edgebury. 1.4 A pre-application consultation has been undertaken with LB Bromley (LBB) and their response has been provided within Appendix B. 1.5 A site visit was undertaken on 04 November 2020 to review the highway conditions. 1.6 This Transport Assessment follows advice from Central Government in the form of the National Planning Policy Framework [NPPF] (February 2019) and the Planning Practice Guidance [NPPG] (March 2014). 1.7 The site is located close to numerous bus routes and therefore the proposed development will be designed to promote sustainable travel and to reduce the impact of private vehicle use on the highway network. To reinforce this, a framework School Travel Plan will accompany this Transport Assessment to encourage staff members and visitors to access information on sustainable travel options. Ref: 004_4200426_DK 1 Issue 2: 03 February 2021 2.0 Policy Review 2.1 This section provides a brief review of the key national, regional and local policy documents which underpin the development of the site from a transport and highways perspective and those which have been taken into account through both the masterplanning process as well as the drafting of this Assessment. The Planning Statement submitted in support of the proposed development will provide a more comprehensive overview of all relevant planning policy. National Policy National Planning Policy Framework (NPPF) and Guidance (NPPG) 2.2 The national policy documents, which set the context for this development proposal, include: • The Future of Transport White Paper - A Network for 2030 (2004); • National Planning Policy Framework (NPPF – February 2019); and • National Planning Practice Guidance on Travel Plans and Transport Assessments (2014). 2.3 A key thread of national policy is to ensure the provision of a transport network that can meet the challenges of a growing economy and the increasing demand for travel, but can also achieve social and environmental objectives to support strong but sustainable communities. As with the previous NPPFs issued in 2012 and 2018, the updated policy continues to encourage a presumption in favour of sustainable development which is tailored to local circumstances. 2.4 The NPPF seeks to integrate planning and transport at the national, regional, strategic and local level in order to: • Balance transport systems in favour of sustainable transport modes; • Promote accessibility to jobs, shopping, leisure facilities and services by public transport, walking and cycling; • Promote social interaction and support healthy lifestyles through the provision of street layouts with good pedestrian and cycling connections between neighbourhoods; • Ensure safe and suitable access to the site can be achieved by all people; and • Minimise the length of routes to key facilities such as primary schools and local shops. 2.5 The NPPF also identifies that transport issues should be considered from the earliest stages of a project, so that: • Potential impacts on transport networks can be addressed; • Opportunities from existing or proposed transport infrastructure can be realised; • Opportunities to promote walking, cycling and public transport use are identified and pursued; • The environmental impacts of the traffic and transport infrastructure can be identified, assessed and taken into account; and Ref: 004_4200426_DK 2 Issue 2: 03 February 2021 • High quality places can be designed once the patterns of movement, streets, parking and other transport issues have been considered. 2.6 The Policy document also states that planning applications should: • Support the appropriate mix of uses and within larger sites, minimise the number and length of journeys needed for employment, shopping, leisure, education and other activities; • Actively involve the local highway authorities and other transport infrastructure providers such that strategies for supporting sustainable transport are aligned; • Identify and protect routes which are critical in developing infrastructure to widen transport choices; and • Provide high quality walking and cycling networks and supporting features such as cycle parking. 2.7 Likewise developments should also ensure: • Appropriate opportunities to promote sustainable transport modes that can be taken up, given the type of development and its location; • Safe and suitable access can be achieved for all users; and • Any significant impact on capacity and congestion or on highway safety can be mitigated. 2.8 Whilst opportunities to maximise sustainable travel use should be actively encouraged, the NPPF recognises that these opportunities will vary between urban and
