The application proposed 34 dwellings as the third phase of development to the south east of Damask Way on the south side of Warminster and was supported by a Transport Statement produced by IMA Transport Planning in December 2017. 1.1.2 Following the planning application, the access arrangement was revised in consultation with Wiltshire Council and agreement was reached with the Local Highway Authority (LHA) on an arrangement to serve 34 dwellings. 1.1.3 The development scheme was subsequently revised to address other matters arising from the consultation responses received and a development of 28 dwellings is now proposed, served via the access arrangement agreed for the larger scheme. 1.1.4 This Transport Statement has therefore been revised to reflect the access arrangements that the LHA agreed to be suitable for the 34-dwelling scheme and the effects of reducing the scheme to 28 dwellings. 1.1.5 A section has also been added to the Transport Statement to address issues raised in a Highways Statement produced on behalf of a local residents group. 1.2 Background 1.2.1 The site is the third phase of development to the east of Upper Marsh Road. Application W/12/00687/OUT was granted consent in 2013 to construct up to 23 dwellings off an extension to Damask Way, now fully built out (reserved matters consent 14/03655/REM), with an emergency access onto Upper Marsh Road. 1.2.2 The second phase was a small extension to the first phase (consents 15/01661/OUT & 1512197/REM), adding 5 units on a shared private drive off an upgraded section of the first phase emergency access, also now built out. 1.2.3 The development site is over a spur of raised land to the south and east of the first two phases and is generally sloping away from the built-out development. 1.2.4 A pre-application inquiry (17/08219/PREAPP) was submitted to Wiltshire Council with a scheme using an upgrade to the first phase emergency access, with a left- in/right-out arrangement aimed at minimising construction works. 1.2.5 A framework document for a Transport Statement was included with the submission, which drew highway comments summarised as follows (included in full in Appendix TS-1): · The principle of residential development in this location is accepted. · Upper Marsh Road is narrow and lacks pedestrian facilities but widening proposed by the development will improve the situation. · Adequate access and visibility is essential with an all-movement junction to fully accommodate servicing, refuse collection and emergency access. · Long-sections of the access will be required to demonstrate a maximum gradient of 1 in 30 over the first 9m of the access and 1 in 12.5 thereafter. · An Automatic Traffic Count will be required to establish actual speeds and hence visibility splay requirements. · Up to 25 dwellings could be served by a 4.5m carriageway, 1.5m footway and 0.5m margin opposite, or a 5.5m shared surface with 1m verge. ___________________________________________________________________________ Transport Statement (Post-Application) – Upper Marsh Road, Warminster IMA-17-167 TS v4-1 (Post-App) March 2018 3 IMA-17-167 · If more than 25 dwellings are proposed, a 5.5m road with 2m footways either side would be required, or a 5.5m shared surface with a 2m service strip and a 0.5m margin opposite. · The Transport Statement framework sets out a satisfactory approach. · The development should upgrade and surface the existing footpath running through the site to a 3m wide shared use path, providing adequate pedestrian and cycle access to the nearby Lake Pleasure Grounds. 1.2.6 The December 2017 Transport Statement was prepared in the context of the pre- application input from the LHA. This updated document reflects the post- application negotiations carried out with the LHA regarding the access proposals. 1.3 Scope of the Report 1.3.1 The existing site and the immediate surroundings are described, including nearby committed development and local transport infrastructure. 1.3.2 The section on baseline transport data commences with a summary of the facilities that can be reached without a car. Local census data on commuting patterns is then considered. Traffic patterns on the local highway network are examined, via surveys agreed with the LHA at the pre-application stage. 1.3.3 The development proposals are described, including details of an all-movement access arrangement that has been designed in consultation with the LHA and has their agreement. Parking provision and likely trip generation by all key modes are set out, with the likely distribution of peak period traffic on the local highway network, which has been agreed by the LHA. 1.3.4 The likely change in travel demand for 34 dwellings was agreed by the LHA and this has been revised on the same basis to reflect the reduced scheme. The change in traffic patterns is quantified and illustrated diagrammatically and the implications for existing facilities and infrastructure considered, with the mitigation measures agreed with the LHA post-application set out. 1.3.5 The issues raised in a Highways Statement produced on behalf of local residents are addressed individually in the context of a scheme that has the agreement of the LHA and has since been reduced
