Six trees were assessed due to being in proximity to the proposed development as indicated on the
Draft Proposals.

Trees situated adjacent to the road outside of the development footprint which were not collected,
however, should be afforded tree protection measures due to the expected movement of vehicles
and machinery. These impacts are expected to be negligible due to the existing use and constraints
of the area and temporary fencing is proposed in order to mitigate any accidental encroachment or
storage of materials within these areas.


3.2.1 Risk Assessment
Assessment of the risk presented by the trees was undertaken using the Quantified Tree Risk
Assessment (QTRA) system. The most likely failure is deadwood or small diameter green branches.
Based on a Target value of 4; a Size value of 4 and a Probability value of 5, a Risk of Harm (RoH)
of less than 1 in 1million is calculated, ie. the tree is a Broadly Acceptable risk.
