BS 5837:2012 Tree Surveys & Reports for Planning and Development

Crofton Trees - Arboricultural Consultants If trees are located in the vicinity of a construction or demolition site, the Local Planning Authority (LPA) will normally require that a tree survey is carried out and a report produced in compliance with British Standard BS 5837:2012 Trees in relation to design, demolition and construction in support of a planning application.

This process will normally be carried out in 2 stages:

  • Stage 1:

    Survey: An initial survey of the trees on the site and any off-site trees that may be impacted on by a proposed development. We record the trees’ locations, species, dimensions, age classes, physiological and structural condition and potential; and categorise them in accordance with BS 5837. These details are then presented as a tree survey schedule.

    Tree constraints plan and short report: These detail the constraints associated with trees, both below ground (root protection areas) and above ground (existing canopy spreads). This will enable an informed design layout to be produced which considers the constraints posed by trees on or adjacent to the site and which is likely to be acceptable to the LPA.

  • Stage 2:

    Once a design layout has been finalised then we will assess the implications of the proposed site layout on trees worthy of retention; and in the absence of any significant adverse impacts likely to lead to refusal , we will produce an arboricultural impact report, prepared in accordance with BS 5837 which will be submitted to the LPA in support of a planning application along with a tree protection plan (TPP), showing how trees to be retained are to be protected from damage during development.

    Often the Local Planning Authority will place a condition once planning permission has been granted for an Arboricultural method statement (AMS) to be submitted prior to the commencement of any works. This should be prepared in accordance with BS 5837, setting out design details and demolition and / or construction methods necessary to avoid unacceptable damage to retained trees; and specifying protection measures to be deployed during development.

    Arboricultural site supervision is often also required as a condition to ensure that tree protection plans are being adhered to and to offer expert on site advice so that works can continue smoothly without interruptions.

    We work closely with Planners, Architects, Engineers and Tree Officers to achieve a successful, innovative design where trees can exist as an integral part of the overall development.
