KM/192821/Reports/192821-04 (ii) ELTHAM HIGH STREET – MIXED USE DEVELOPMENT 192821-04 TRANSPORT ADDENDUM July 2020 _________________________________________________________________________ 1.0 INTRODUCTION 1.1 Ardent Consulting Engineers (ACE) has been appointed by Quanta Homes to advise on the highways/transportation aspects of the proposed residential led development at an existing commercial unit at 260 Eltham High Street, Royal Borough of Greenwich. 1.2 This Transport Addendum has been prepared to support an appeal against the decision of the Royal Borough of Greenwich (RBG) to refuse application reference 19/4200/F. 1.3 The appeal site address is 260 Eltham High Street, Eltham, London SE9 1AA (the Site). In summary, the appeal proposal relates to a full planning application for the demolition of the existing commercial buildings on site and the erection of four buildings, ranging between 2 and 4 storeys, providing 67 apartments, 4,000sq ft (380 sq. m) of commercial floorspace, and associated development. 1.4 The description of development is: ‘Demolition of existing commercial buildings at 260 Eltham High St, partial demolition of existing buildings at 2-4 Southend Crescent and erection of 4 buildings ranging in heights of 2-4 storeys to provide approximately 380 sqm of commercial floor space and 67 residential apartments, including associated landscaping, car parking, access, refuse storage and cycle storage.’ 1.5 The RBG decision notice dated 07/04/2020 provided 7 reasons for refusal, none of which were related to highway or transportation. However, this Transport Addendum (TA) has been produced to provide clarity on the revised highways and transportation elements of the proposal, providing further detail to comments made by both Transport for London (TfL) and RBG as part of the consultation process, as well as more recent discussions with officers. KM/192821/Reports/192821-04 1 ELTHAM HIGH STREET – MIXED USE DEVELOPMENT 192821-04 TRANSPORT ADDENDUM July 2020 _________________________________________________________________________ 1.6 It is noted that RBG Highway Officers stated within the committee report that: - ‘Overall, the transportation element of the proposal is considered to be acceptable, subject to compliance with appropriate conditions and planning obligations. Therefore it is considered that the development will have an acceptable impact on the surrounding highway network. For this reason, the application is consistent with policies 6.3, 6.10, 6.11 and 6.13 of the London Plan 2016 and policy IM4 and IM(c) of the Core Strategy 2014. Report Structure 1.7 Following this introduction, this report is structured as follows: - • Section 2.0 considers the planning background and discussions with RBG Highway Officers and TfL; • Section 3.0 comments on the vehicular and pedestrian access to the site; • Section 4.0 summarises the site accessibility, existing parking situation and proposed level of parking; • Section 5.0 details cycling and sustainable travel measures; • Section 6.0 sets out detail on delivery, servicing, construction and contributions • Section 7.0 provides summary and conclusions. KM/192821/Reports/192821-04 2 ELTHAM HIGH STREET – MIXED USE DEVELOPMENT 192821-04 TRANSPORT ADDENDUM July 2020 _________________________________________________________________________ 2.0 PLANNING BACKGROUND AND OFFICER DISCUSISONS 2.1 Discussions were undertaken with highways officers both before and after submission of the application, relating to: - • proposed levels of parking, with parking surveys undertaken with the scope agreed with officers and the proposed levels of parking being accepted. • Accessibility, which was discussed in detail, particularly the site’s PTAL (Public Transport Accessibility Level), and proximity to Eltham High Street, local jobs and facilities in relation to the level of parking proposed. • Contributions sought relating to sustainability, improvements to the highway in the vicinity of the site and lighting. • Provision of improvements to the pedestrian link to the eastern side, improving connectivity to the bus stops on Southend Crescent • Requirement for the quantum and design of cycle parking to accord with the ‘intend to publish’ London Plan and London Cycle Design Standards. • Provision of a condition requiring more detail on construction to be provided, including the provision of a Construction Environmental Management Plan (CEMP)/Construction Logistics Plan (CLP). 2.2 The above has been discussed with both RBG/TfL, and the principle of these off-site works in the immediate vicinity of the site, and conditions are considered acceptable. The design itself has also been slightly amended responding to recent discussions, and the above. KM/192821/Reports/192821-04 3 ELTHAM HIGH STREET – MIXED USE DEVELOPMENT 192821-04 TRANSPORT ADDENDUM July 2020 _________________________________________________________________________ 3.0 VEHICULAR AND PEDESTRIAN ACCESS Main Vehicular Access 3.1 The site is accessed off Eltham High Street A210 via a dedicated arm of the Eltham High Street/Westmount Street/Bexley Road Southend Crescent signalised junction. 3.2 The existing vehicular access for the site is to be retained in its current location, with the current crossover arrangement to be upgraded and improved. Further detail on the access would be provided as part of the detail design/S278 agreement, with improvements made the footway in the vicinity of the access. 3.3 The indicative access arrangement is shown on ACE Drawing 192821-04 It is proposed that the existing site access would be revised, with the signal pole relocated and the induction of an loop/microwave detector type system to detect a vehicle waiting to leave the site and call the required stage/phase within the signal junction control sequence, with the existing push button arrangement removed. The site access stop line would be set back in this scenario to allow suitable space for a vehicle to access the site when a vehicle is waiting to egress. However, contrary to the existing arrangement, all infrastructure associated with the operation of the junction could be provided within the adopted highway, which is a significant improvement as the existing push button is located within private land, behind a gate. 3.4 A LinSig model for the traffic signals at Eltham High Street/Southend Crescent/Westmont Round was produced to determine both the existing and anticipated future operation of this junction, which was submitted as part of the Transport Assessment submitted with the application. 3.5 This assessment concluded that the impact of the proposed development would not result in any material change in the operation KM/192821/Reports/192821-04 4 ELTHAM HIGH STREET – MIXED USE DEVELOPMENT 192821-04 TRANSPORT ADDENDUM July 2020 _________________________________________________________________________ of the junction when comparing the existing situation with the proposed. This assessment also highlighted that, with the proposed development, the extra stage calls from the site access would generally lead to slightly reduced green times for the A210 approaches, with little change for either Westmount Road or Southend Crescent. In terms of delays to buses, the average additional delay is about 6 seconds per PCU (Passenger Car Unit) during the weekday AM peak which does not represent a material increase over a bus route, with no comment raised on this in the consultation responses from TfL/RBG. 3.6 Both TfL and RBG have accepted the modelling assessment within the TA, with no concerns or comments raised. 3.7 The proximity to the adjacent Woodcroft Club access was also discussed, although it was agreed that the detail design of this access could be agreed with TfL/RBG and addressed through conditions with RGB stating: ‘the sight lines between the [proposed site] access and that of the adjacent ‘in’ Conservative Club access and considering the signal timings, is not seen that unacceptable conflict would arise’. Secondary Pedestrian/Cycle Access 3.8 A secondary pedestrian/cycle access is located on the southeast corner of the site, off Southend Crescent which will be retained for pedestrian access,
