A tree constraints plan is one kind of design tool which if used in the preliminary round of designing any site would be of great help to designers, developers, residents and authorities. Any professional and experienced environmental consultant knows that a tree constraints plan is a layout plan for the development site which is prepared to scale and show the surrounding buildings, the proposed development as well as any trees that are there around the site in question. The things that tree constraints plan should include are following:
- Age class
- Category grading
- Stem diameter taken at 1.5m from ground level
- Height
- Physiological condition
- Height of crown clearance above ground
- Structural condition
- Preliminary management requirements
- Tree species
- Estimated safe useful life expectancy
- Branch spread (in four directions North, East, South and West)
The tree constraints plan will show the stem, canopy spread, and root protection area of each tree. Hence, in order to consider trees at the outset of the development, it is good to have such thorough tree survey so that the development of the site can be saved from the refusal of the planning permission. As, the planning authority has the right to reject the development proposal to on the grounds that trees were not considered in the plan. The tree constraints plan must have correct information gathered during topographical survey and an accurate tree survey. The topographical survey will have information on the location of all trees surrounding the development site, shrubs and hedges and other relevant features such as streams, buildings and spot level heights. Now, in order to carry out tree survey, you need to take the help of environmental consultant as it needs to be carried out in accordance with BS 5837 (2005). Professional ecological consultancy has specialist Arboriculture team which knows what it is to create tree constraints plan as part of powerful and cost-effective Arboriculture solutions.
