Tree constraints plan

tree constraints plan


A tree constraints plan will plot the root protection areas (RPA) and any other relevant constraints  around each of the category A, B and C trees on relevant drawings.


Root Protection Areas (RPA) represent below ground constraints. Above ground constraints might arise from the current and ultimate height and spread of the tree and species characteristics including foliage density, honeydew drip, branch drop and fruit fall.


These attributes can significantly affect potentialland use or living conditions, including the effect of the tree on daylight shading.



The following factors will also be taken into account during the design process:


a) the presence of tree preservation orders, conservation areas or other regulatory protection;


b) potential incompatibilities between the layout and trees proposed for retention;


c) the working and access space needed for the construction of the proposed development. This might involve access facilitation pruning, or the use of a height restriction bar to prohibit tall vehicles accessing a site containing trees with low canopies.;


d) the effect that construction requirements might have on the amenity value of trees, both on and near the site, including the effects of pruning to facilitate access and working space;


e) the requirement to protect the overhanging canopies of trees where they could be damaged by machinery, vehicles, barriers or scaffolding, where it will be necessary to increase the extent of the tree protection barriers to contain the canopy;


f) infrastructure requirements in relation to trees, e.g. easements for underground or above-ground apparatus; highway safety and visibility splays; and other infrastructural provisions, such as substations, refuse stores, lighting, signage, solar collectors, satellite dishes and CCTV sightlines;


g) the proposed end use of the space adjacent to retained trees;


h) the potential for new planting to provide mitigation for any losses.
