Transport Statements and Assessments in Wiltshire

What transport evidence a Wiltshire planning application needs, the parking standards that apply, and the policies an assessment should address.

Which document do you need?

National policy asks for a Transport Statement or a Transport Assessment wherever a development will generate significant amounts of movement.

Transport Statement

A shorter document for smaller schemes where transport issues are limited: access, parking, trips and sustainable travel.

Transport Assessment

A full assessment for larger schemes: trip generation, network impact, junction capacity and mitigation.

Parking standards

Wiltshire's Core Strategy (January 2015), Core Policy 64, bases residential parking on minimum standards and limits private non-residential parking to maximum standards, taken from the council's Car Parking Strategy (adopted February 2011). Check the current standards with the Council early.
