Tree protection plan

Tree protection plan


The tree protection plan will be superimposed on a layout plan based on the topographical survey and showing all hard surfacing and other existing structures within the root protection area (RPA).


The plan will clearly indicate the precise location of protective barriers to be erected to form a construction exclusion zone around the retained trees. It will also show the extent and type of ground protection, and any additional physical measures, such as tree protection boxes, that will need to be installed to safeguard vulnerable sections of trees and their RPAs where construction activity cannot be fully or permanently excluded.


The measures will be indicated on the plan and accompanied by descriptive text as required. Barrier and ground protection offsets will be dimensioned from existing fixed points on the site to enable accurate setting out. The position of barriers and any ground protection will be shown as a polygon representing the actual alignment of the protection.


Where temporary access is to be permitted into a construction exclusion zone, the extent of the set-back of the permanent barrier will be clearly indicated, along with the temporary ground protection measures to be adopted for the duration of the works within the RPA.


To avoid disturbance to the physical protection allowance will be made for all construction operations which will be undertaken in the vicinity of trees. Factors that will be considered include, but are not limited to:


a) site construction access;


b) the intensity and nature of the construction activity;


c) contractors’ car parking;


d) phasing of construction works;


e) the space needed for foundation excavations and construction works;


f) the availability of special construction techniques;


g) the location and space needed for all temporary and permanent apparatus and service runs, including foul and surface water drains, land drains, soakaways, gas, oil, water, electricity, telephone, television or other communication cables;


h) all changes in ground level, including the location of retaining walls, steps and making adequate allowance for foundations of such walls and backfillings;


i) working space for cranes, plant, scaffolding and access during works;


j) space for site huts, temporary toilet facilities (including their drainage) and other temporary structures;


k) the type and extent of landscape works which will be needed within the protected areas, and the effects these will have on the root system;


l) space for storing (whether temporary or long-term) materials, spoil and fuel and the mixing of cement and concrete;


m) the effects of slope on the movement of potentially harmful liquid spillages towards or into protected areas.
