Visual Tree Assessment (VTA)

A VTA is undertaken to assess the condition of a tree on your site. The tree will be visually assessed for signs of any structural defects, using the Visual Tree Assessment methodology, a schedule will be prepared detailing Tree Number, Species, Stem Diameter, Height, Crown Spread, Age Class, Physiological Condition, Structural Condition and Re-inspection Period. Details of any structural defects and of any works required to bring the tree into a safe condition will be provided.


Arboricultural Impact Assessment (AIA)

The Arboricultural Impact Assessment (AIA) will evaluate the direct and indirect impacts of a proposed development and consider the following factors:

  • The presence of Tree Preservation Orders (TPOs)
  •  The effect of the development of the amenity value of the trees
  • The above & below ground constraints
  • The construction of the proposed development - working space, layout etc.
  • Whether the development design can be modified to accommodate the retention of trees that may be at risk of being lost
  • Infrastructure requirements
  • End use of the space
  • The potential for new planting to provide mitigation for tree losses
  • Where appropriate a draft Tree Protection Plan will be included along with details of issues to be addressed by an Arboricultural Method Statement
  • Trees for retention
  • Trees to be removed
  • Location of protective barrier & other relevant physical protection measures (including ground protection)
