Tree Constraint Plans

A Tree Constraint Plan accompanies all of our Preconstruction Feasibility Surveys and Arboricultural Impact Assessments.

The Tree Constraint Plan is a clear and accurate plan, drawn using AutoCAD, which is plotted directly onto a topographical site survey. It contains the positions and dimensions of all trees on a site at the time of the initial survey. The Tree Constraint Plan helps to inform future tree management and tree preservation and protection plans.

The tree dimensions used on a Tree Constraint Plan include the crown spreads measured at the four cardinal compass points to create a realistic intimation of their shape. The Tree Constraint Plan will also include root protection areas to indicate both the above and below ground constraints the trees pose. The categorisations of tree quality in accordance with BS5837:2012 (2005) are also indicated on the plan and colour-coded for easy interpretation.

The Tree Constraints Plan is a tool that can be used to aid in development of a site plan that maximises the available space whilst taking into account the constraints caused by trees. Tree constraints may include shading, space for future root and crown development and routing for overhead and underground services.
