BS 5837 Trees In Relation To Design, Demolition And Construction
"Providing a comprehensive, cost effective service to aid planning conditions relating to trees"
BS5837 ‘Trees in relation to design, demolition and construction’
The Town and Country Planning Act (1990) places a duty on the Local Planning Authority to consider the impact of development proposals on existing trees within a site, whether subject to statutory protection or not. British Standard 5837:2012 Trees in Relation to Design, demolition and Construction- Recommendations provides current Best Practice advice. This standard requires that arboricultural advice is obtained at the very outset of any development, and that advice and supervision is continued through to final completion.
BS5837 Tree Survey
We will undertake an initial Tree Survey of the site grading the quality and size of trees and other vegetation according to their condition, prospective longevity and amenity value within the landscape. The tree survey will also identify the extent of structural tree roots and canopies. Dangerous trees, or those with a very short life expectancy are normally recommended for removal, with the remaining trees graded as high, moderate or low. Root protection areas are calculated and included on a tree constraints plan, together with potential height and shade cast by relevant tree species, where these have a future potential to impact further on the site.
The proposed development area is clearly defined together with the initial tree protection measures. This plan provides a design tool on which to develop initial site layouts. If followed, it will greatly reduce potential conflicts between the layout and the planning system, significantly reducing the time spent on design amendments.
Constraints reports are useful when considering purchasing some land for a project or when design is still in the conceptual stage. An initial BS 5837 Survey will be carried out to collect data and grade trees on site. Following this you are provided with a Constraints Report/Tree Plan which identifies significant trees on site that will need to be considered during planning. In the long term, this can save money in two ways. For clients considering the purchase of land knowing constraints prior to purchase can be invaluable and aid in decision making regarding the purchase. For clients in the early stages of design knowing constraints from the outset means that architects can design with constraints in mind and incorporate specialist techniques where necessary limiting design amendments at a later stage.
Arboricultural Impact Assessments
We provide assessments of proposed layouts, highlighting areas of conflict between the design and trees that need to be overcome at the design stage. This minimises delays during the planning process. Where minor conflicts cannot be resolved, special engineering measures can be devised to overcome any impact with retained trees.
Arboricultural Method Statements & Tree Protection Plan
This document provides detailed advice on specialised design requirements, construction/demolition techniques and all tree protection requirements from site initiation through to final completion. It aims to support the Planning Application, to discharge Planning Conditions and provide a working document for site personnel. The document also provides substantial support should an application progress to Appeal or Inquiry.
Protecting existing mature trees saves money whilst increasing property values providing new builds with a mature feel. The value such trees provide is almost impossible to replace. These trees also provide important habitats for species including nesting birds, bats and other wildlife protected by legislation, helping developers score BREEAM points and benefit future communities.
