Arboricultural Impact Assessment

Arboricultural Impact Assessment

An Arboricultural Impact Assessment (AIA) is required by Local Planning Authorities (LPA), to support any planning application which has the potential to affect existing trees within or adjacent to a proposed development site. The report is compiled in accordance with BS 5837: 2012 ‘Trees in relation to design, demolition and construction – Recommendations’ and provides survey information on the trees including their amenity value, any hazards they may pose to the site, information on the impact of the proposed development from an arboricultural perspective. The report is then supported by a Tree Survey Plan supplying; the location, canopy size, amenity value and root protection area associated with each tree; and a Tree Protection Plan overlaying the tree locations with the proposed development, trees for removal and where protection/specialist construction is required to retain trees.

Private sector

Arboricultural Impact Assessments are not only required within large development sites. Local Planning Authorities will often require an AIA to be carried out on small private sites including domestic extensions, conservatories, driveways and any other projects which will require excavations in the proximity of existing trees. This is especially the case when the project falls within a conservation area, or there are trees subject to a TPO (Tree Preservation Order) in the location. By contacting D F Clark Bionomique for advice prior to submitting your planning application, we can save you unnecessary delays, penalties and amendments by incorporating sound arboricultural advice from the outset.

Commercial Sector

All commercial developments which have the potential to affect existing trees within or adjacent to a proposed site will require an Arboricultural Impact Assessment to satisfy planning. By contacting D F Clark Bionomique during the early stages of your project, an Arboricultural Site Appraisal can be undertaken to highlight potential development constraints from the outset. By highlighting these constraints and working with the design team during the early stages of a project, various issues may be immediately negated through careful design of the proposal. This will allow the planning application to pass without expensive and time-consuming adjustments to the scheme or lengthy delays clearing pre-commencement conditions.

Arboricultural Impact Assessment – Please don’t hesitate to contact us for detailed information

Stage 1 (Design/feasibility stage)

  • Tree survey to BS 5837:2012 ‘Trees in relation to design, demolition and construction – recommendations’
  • Tree survey sheets
  • Tree Survey Plan showing categorisation and above and below ground constraints
  • A developable area in terms of arboriculture or constraints in relation to preliminary design.
  • Short report highlighting constraints and opportunities for the design team and ongoing email/phone dialogue with the team
  • A Tree Preservation Order/conservation area check, upon request

Stage 2 (Planning application stage)

  • An Arboricultural Impact Assessment based on stage 1 and the proposed layout suitable for Local Planning Authority (LPA) submission
  • A tree surgery schedule
  • A Tree Protection Plan showing suitable tree protection, retention and removals
  • Outline for an Arboricultural Method Statement
