Arboricultural Impact Assessments
Within the planning process, an understanding is needed of how any proposed development or construction will impact the trees on site. This requires a particular type of tree survey known as an Arboricultural Impact Assessment (AIA), and is needed with the submission of a full planning application.
Tree removal is one of the most significant and recognisable impacts a development can have. However, there are many more ways in which construction can impact trees without being removed. For example, movement of construction machinery across root areas, excavation within the root area and the construction of hard surfaces can all affect a tree if it is not adequately protected.
The Arboricultural Impact Assessment (AIA)
The Assessment identifies all possible impacts of a proposed development design to the trees on a site and identifies which trees will require removal and those which can be retained with protection measures applied.
For retained trees, the Arboricultural Impact Assessment (AIA) identifies the effect of the proposed development on the impacts below ground (the roots), as well as the impacts above ground (the crown).
Arboricultural Impact Assessments also identify the impact the trees themselves will have on a future development, such as from shading and production of leaf litter. This allows designs to consider the positioning of any building or extension and avoid pressure for tree removal or pruning at a later stage.
Tree Assessment Plans
As part of the Arboricultural Impact Assessment, a Tree Assessment Plan (TAP) is produced using the Tree Constraints Plan (TCP) and the design proposals. This Tree Assessment Plan highlights where the impacts are and outlines potential mitigation and tree protection measures that will be needed to protect the trees being retained.
