The development proposals involve the demolition of the existing Aylesbury Estate and construction of 3,560 dwellings (2,647 of which replace existing units). The development proposals include construction of: Ŷ Early Years Facilities; Ŷ An Extra Care Facility; Ŷ A Learning Disabilities Centre; Ŷ Medical centre; Ŷ Community centres; Ŷ Retail units; and Ŷ Employment units. Many of the non-residential uses re-provide existing facilities within the site as part of the new masterplan, but provide new facilities tailored to the new site layout. The Aylesbury Regeneration area is well situated for travel by sustainable modes of travel, with a very low car mode share in the local area. The site is located close to local shops and facilities which are within a short walk. There are good quality bus links from the Aylesbury Regeneration area. In the future, improvements to street and bus networks are predicted to improve the accessibility (PTAL score) of the Aylesbury Regeneration area. The accident records indicate that there are no unusual accident patterns/ clusters within the study area. A number of accidents were recorded in the study area, but the causes of these accidents do not indicate any overall trends. Traffic capacity analysis indicates that the majority of the junctions in the study area are currently operating with spare capacity due to reductions in vehicle traffic in recent years. The future scenario traffic modelling indicates that the majority of the existing junctions will operate satisfactorily. Works are proposed to Albany Road to improve the public realm, create a ‘Park Road’ and increase pedestrian connectivity to Burgess Park. These measures are predicted to reduce traffic capacity at the Portland Street, Wells Way and Thurlow Street junctions. It is considered that this capacity reduction is acceptable in line with the desire to improve the environment for pedestrians and cyclists and to meet the aspirations of the AAAP. It is acknowledged that wider area cycle strategies are currently being prepared by Southwark Council that may affect the area, particularly Portland Street and Albany Road. Flexibility in the highway design has been provided to allow schemes to be developed without adversely affecting the development proposals. The pedestrian and cyclist trips from the proposed development are not predicted to have a significant impact on the local area, with trips dissipating into the permeable street network towards key destinations such as Elephant and Castle Station, Walworth High Street and local schools. It is predicted that the proposed development will have an impact on local bus services, particularly those services which run through or past the Aylesbury Regeneration area on Albany Road and Thurlow Street. A financial contribution will be made to TfL towards improving bus services through the Aylesbury Regeneration area. 5 In addition to the financial contributions, the following mitigation measures will be provided as part of the development proposals: Ŷ 16 car club parking spaces (to be operated/ managed by the Southwark Council’s car club operator Zipcar), plus a contribution towards their operation. Ŷ Improved pedestrian routes within the Aylesbury Regeneration area; Ŷ Quiet, cycle friendly streets within the Aylesbury Regeneration area; Ŷ Infrastructure for installing London Cycle Hire docking stations in the site; Ŷ Car and cycle parking; Ŷ Site-wide Travel plan; Ŷ Delivery and Servicing Plan; and Ŷ Construction Logistics Plan. During construction of the development, HGV movements will be carefully managed, with particular emphasis on cycle safety. Adjacent to the site, alternative pedestrian and cycle routes will be provided where temporary closures are required. In conclusion, this Transport Assessment has been prepared to assess the impact of the proposed Aylesbury Regeneration on the transport network surrounding the site. The site proposals are for the complete regeneration of the area with the demolition of the existing buildings and the construction of a new network of streets providing a mix of housing, flats and other facilities. The development proposals are considered to offer a positive transport benefit to the local area by: Ŷ introducing a more permeable street network for pedestrians and cyclists; Ŷ improving the environment for pedestrians and cyclists within the site; and Ŷ improving public transport services and accessibility in the local area. The proposed urban realm scheme on Albany Road also provides improvements to facilities for pedestrians and cyclists. Overall, it is considered that the transport impacts of the development are mitigated by the proposals and that there is no reason to refuse the development on transport grounds. Project number: 50600304 Dated: 23/09/2014 6 Revised: 2 Introduction 2.1 Purpose of Report 2.1.1 This document is the Transport Assessment (TA) relating to the proposed regeneration of the Aylesbury Estate in Southwark. The Transport Assessment accompanies the planning application to provide information on the implications for the transport network of the development proposals. It has been prepared so that can be read standalone document, further information on non-transport aspects of the proposals can be found in the other planning application documents. 2.1.2 A Transport Assessment considers the major modes of transport and provides a review of the existing situation, analysis of the likely conditions after development and recommends any mitigation measures that may be necessary. 2.1.3 The scope of this document was established using the Transport for London (TfL) ‘Transport Assessment Best Practice Guidance, 2010’. The details of the scope of assessment were then the subject of discussions with the London Borough of Southwark (LBS) and TfL through formal pre- application consultation. 2.1.4 The redevelopment of the area considered in this TA is being progressed as two planning applications. Ŷ Application 1 – ‘First Development Site’ detailed application; and Ŷ Application 2 – ‘Masterplan’ outline application. 2.1.5 The extent of the applications is shown on Figure 1. A site location plan that looks at the site in a wider context if provided as Figure 2. 2.1.6 This document generally considers the combined effects of development of both of the above applications and all references in this document to the development proposals should be considered to be the combination of both of the above applications. However, a separate detailed assessment of the First Development Site (FDS) is provided at Appendix A. This considers the effects should the FDS happen as a standalone development. 2.2 Report Structure 2.2.1 The remainder of Section 2 of the TA sets out some background to the development proposals, the policy that applies to the development and information about committed developments that have been taken into consideration. 2.2.2 Section 3 of the TA provides information on the existing transport conditions across all major modes of travel and provides a review of traffic accident statistics. 2.2.3 Section 4 of the TA explains how the future trip generation of the proposed development has been established and distributed onto the transport network. 2.2.4 Section 5 considers the impacts of the change in vehicle traffic levels on the road network. 2.2.5 Section 6 considers the impacts of the change in pedestrian and cycle movements on the highway network. 2.2.6 Section 7 considers the impacts of the change in public transport users
