Tree Survey in line with BS5837

All property development projects, which are located on sites with trees require Tree Survey. The main data collected are dimensions of the tree including diameter in the breast height (DBH) from which the Root Protection Area around the tree is calculated. The survey also evaluates the condition of a tree and grades it to one of the four retention categories.

Tree Retention Categories

Category A

Trees of high quality and value, with an estimated life expectancy of at least 40 years.

Category B

Trees of moderate quality and value. An estimated life expectancy of at least 20 years.

Category C

Trees of lower quality and value. An estimated life expectancy of at least 10 years, and with a stem diameter of up to 150mm measured at 1.5m from ground level.

Category U

Dead, dying or unsuitable trees for retention. Life expectancy of less than 10 years.

Tree Constraints Report

On the basis of the Tree development survey we can produce the report, which identifies constraints of the site referring to a Root Protection Area and amenity value of trees. The document help landscape architects to find opportunities for a development relating to existing tree population and summarise amenity value and retention category of trees on site.

Arboricultural Impact Assessment

The Arboricultural Impact Assessment is required as a supplement for the planning application. The report includes the Tree Protection Plan and genuine Arboricultural Method Statement, which can be detailed if the construction methods are agreed by stakeholders. We have extensive experience and expertise in producing Arboricultural Impact Assessments forsmall and large developments from building extension to large multi-unit development schemes.

Arboricultural Method Statement

Often proposed development may be subject of a planning condition. The Arboricultural Method Statement provides detailed information about the protection measures, work sequence, and methodology based on the technical evidence, site constraints. The report is used for discharging planning condition enforced by the Local Authority and serves as a definitive guide relating to existing trees for contractors. We work closely with landscape architects, construction engineers and building contractors to find most feasible solution for more challenging construction situation involving tree protection. We value expert inputs of all sides and create environmentally and economically sustainable output.
