If there are any trees and hedges within a 10m distance where they may be affected by the development an Arboricultural survey will be required. This should include relevant data to British standard 5837:2012-Trees in Relation to Construction - recommendations. Tree trunk and canopy locations should be accurately plotted onto a scale map of the site.
Surveys should include any tree with a stem diameter of more than 75mm measured at 1.5m above ground level. A Tree survey should inform good design and sustainable development. And include the Root protection zones surrounding trees.
Arboricultural Impact Assessment (AIA)
An AIA appraises the effect of the development on trees and provides solutions to any conflicts such as suitable construction methods. This will be required if the Arboricultural survey shows that there may be conflicts between the development and the trees.
Arboricultural Method Statement (AMS)
An AMS should detail protective measures during the construction phase of the development where there are potential conflicts between development and trees. A Method Statement fully details what tree protection measures are needed for all stages of your development, using current best practice and requirements of BS5837:2012 Trees in Relation to Construction recommendations. This may be required at the time of a planning submission or could be required at a later stage as a condition of granted Planning Permission. If required, The Local Authority must approve any Method Statement prior to any work commencing on site.
What is required?
A map to a recognised metric scale, showing the location, size and species of trees/hedgerows, existing buildings, roads and the proposed development
Details of how you intend to protect the trees/hedgerows during the proposed development.
Details of any work proposed to existing trees or hedgerows.
