Proposed Submission Local Plan 2006-2028

Transport Impacts of Development

10.22 All new development is required to address its own transport implications.  Larger schemes are required to prepare Transport Assessments[1] and, where required, Travel Plans to illustrate how the amount of trips generated will be minimized, how the impacts will be accommodated, and how accessibility to the site by all modes of transport will be achieved.

10.23 The Strategic Road Network is formed by Motorways and Trunk Roads, National Primary and County Routes in Somerset. National Primary Routes and County Routes accord with the routes identified in the local Highway Authority's (Somerset County Council) route hierarchy. In order to prevent the unnecessary interruption of traffic flow and to prevent increase of highway hazard, the formation of new direct accesses onto these roads will not be permitted. Exceptions will only be made where the type of development is such that it requires a high order (of route hierarchy) route location, such as roadside service stations or freight transfer facilities.

10.24 Access to development proposed that will connect to rural roads carrying relatively high speed traffic should be designed according to the needs of drivers and other users to enter safely into such traffic. The advice and guidance in the Design Manual for Roads and Bridges will be appropriate in these environments, mostly rural locations. This is likely to be the case for developments related to farm diversification or for tourist attractions specific to rural locations.

10.25 Development proposals will be expected to provide or contribute towards the cost of providing transport infrastructure where this is necessary to make the development acceptable in planning terms[2].

10.26 Contributions may also be required to meet the management and maintenance of services and facilities provided. The appropriate range and level of contributions will be assessed in a comprehensive manner, taking into account strategic infrastructure requirements and using standard charges where appropriate.

10.27 The nature and scale of any planning obligations sought will be related to the form of development and its potential impact upon the surrounding area. In determining nature and scale, specific site conditions and other material considerations including viability, redevelopment of previously developed land or mitigation of contamination may be taken into account. The timing of provision of infrastructure and facilities will be carefully considered in order to ensure that appropriate provision is married against occupation of the development.

Policy TA5: Transport Impact of New Development

All new development shall be required to address its own transport implications and shall be designed to maximise the potential for sustainable transport through:

i. Safeguarding existing and new transport infrastructure, which is important to an efficient and sustainable transport network from development that would prejudice their transport use

ii. Securing inclusive, safe and convenient access on foot, cycle, and by public and private transport that addresses the needs of all;

iii. Ensuring that the expected nature and volume of traffic and parked vehicles generated by the development would not have a detrimental impact on the character or amenity of the area and would not compromise the safety and/or function of the local or strategic road networks in terms of both volume and type of traffic generated;

iv. Ensuring that proposals, which specifically require a location with direct access to the strategic road network due to the volumes and quality of traffic generated, are well located on these networks. There is a presumption against direct access from the strategic road network. Exemptions will only be made where the type of development is such that it requires a high order (of route hierarchy) route location, such as roadside service stations or freight transfer facilities;

v. Assessing the transport impact of development and ensuring delivery of the necessary transport infrastructure for the proposal and requiring larger schemes to prepare Transport Assessments.

vi. Requiring car parking and vehicle servicing at levels appropriate to the development and its location, in accordance with the approved/adopted standards identified in Policy TA6.

10.28 The following delivery bodies will be key in implementing Policy TA5:

  • South Somerset District Council;
  • Somerset County Council;
  • Developers and Landowners.
